Dental Erosion Assessment Kit for Children: A Complete Guide to GERD-Related Tooth Damage

Dental Erosion Assessment Kit for Children with GERD

A dental erosion assessment kit is a set of simple tools used to check, score, and record the loss of tooth surface caused by acid. In children with gastroesophageal reflux disease (GERD), stomach acid can reach the mouth and slowly wear away the hard outer layer of the teeth.

The kit helps to find this damage early, measure the natural defenses of the mouth, and track changes over time.

Introduction to the Dental Erosion Assessment Kit and GERD-Related Tooth Damage

Dental erosion is the loss of tooth surface caused by acid, without bacteria being involved. It differs from a cavity, which is caused by bacteria, and from wear caused by grinding teeth or brushing too hard.

The hard outer layer of a tooth is called enamel. Under it lies a softer layer called dentin. When enamel wears thin, dentin may become exposed.

GERD means that stomach contents flow back up into the food pipe (esophagus) often enough to cause symptoms or problems. Sometimes this acid reaches the mouth. Stomach acid is strong enough to soften enamel within a short time. Repeated exposure, especially when saliva flow is low, may lead to visible wear.

A dental erosion assessment kit brings together the tools needed for a structured check. It usually covers three areas: how much damage is present, how well saliva protects the teeth, and which habits or conditions may be adding acid to the mouth. This makes the kit useful for children with GERD-related dental damage.

Reflux is common in infants and often settles with time. In some children it continues and needs treatment. Not every child with reflux develops erosion. Studies suggest that erosive tooth wear may be more common in children with GERD, although results differ between studies.

The assessment is non-invasive. It uses light, a small mirror, scoring charts, and simple saliva tests. The standard kit does not use radiation, needles, or drills.

History of Dental Erosion Assessment Tools

Tooth loss from acid has been described in dental and medical writing for many decades. Early reports linked it to acid fumes in some workplaces and to very acidic foods and drinks. During the 20th century, reports also connected long-term vomiting and reflux with a typical pattern of wear, especially on the tongue-side surfaces of the upper teeth.

Early descriptions were written in words only, which made it hard to compare findings between examiners. Scoring systems were created to solve this problem. A well-known tooth wear index was published in 1984. In 2008, a simpler system called the Basic Erosive Wear Examination (BEWE) was proposed. It scores six regions of the mouth and adds the scores together.

Saliva testing developed alongside, mainly through research on cavity risk. Simple strips for pH (a measure of acidity) and buffering (the ability to neutralize acid), together with timed saliva collection, became common tests done during a dental visit. In later years these tools were combined with scoring charts, questionnaires, and photographs into ready-to-use kits for erosive tooth wear.

Adapting the approach for children needed extra steps. Baby teeth have thinner enamel than permanent teeth, so wear may look different and may progress faster. Scoring rules were adjusted in some kits, and gentler ways of collecting saliva were introduced for younger children. Photographs and caregiver-completed questionnaires became common.

Today, no single worldwide standard kit exists. Contents vary between manufacturers and clinics. Most combine a scoring index, saliva tests, photography, and a history form. Research groups also use digital scanners and laboratory tools to measure very small changes in tooth surface, but these are not part of everyday kits.

Expert consensus reports generally support early detection and regular monitoring of erosive wear.

Purpose of the Dental Erosion Assessment Kit and Where It Is Used

The kit is mainly a screening and monitoring tool. It records what is seen and measured in the mouth. It does not treat the teeth, and it does not test the food pipe. Common uses include:

Finding early enamel loss in children known to have GERD or frequent vomiting.
Scoring the extent and location of wear in each region of the mouth.
Measuring saliva flow, acidity, and buffering ability.
Recording baseline photographs and scores for later comparison.
Identifying drinks, foods, and habits that add acid to the mouth.
Supporting a decision to seek medical review of reflux when the wear pattern raises concern.
Checking whether wear is stable or progressing after reflux treatment or diet changes.
Supporting preventive education about tooth protection.

These kits are typically found in:

Pediatric dental clinics and general dental clinics.
Hospital dental units caring for children with complex medical needs.
Pediatric gastroenterology and general pediatric clinics, usually for the history and basic mouth inspection parts.
School-based and community oral health programs.
Research centers studying tooth wear.
Home settings, in a limited way. Some saliva pH strips are sold for home use, but reading them without professional guidance may be misleading.

Key Point: The kit is an assessment and monitoring tool. It is not a test for GERD. Tooth erosion has several possible causes, including acidic drinks and foods. The kit can show that acid damage is present and may suggest a likely cause, but confirming GERD needs a medical evaluation.

Different Types of Dental Erosion Assessment Kits

No single design is used everywhere. The main types are described below.

Basic Clinical Scoring Kit

This type contains a mouth mirror, cheek retractors, a scoring chart, and recording sheets. It is quick and suited to screening. It records damage but does not measure saliva.

Saliva Testing Kit

This type contains collection cups or tubes, stimulation material such as paraffin wax, a timer, and strips for pH and buffering. It measures how well the mouth protects itself against acid.

Photographic and Imaging Kit

This type contains an intraoral camera (a small camera made for the mouth) or a regular camera with retractors and mirrors. Some include software to view images side by side. It is used to build a visual record.

Impression and Study Model Kit

This type contains silicone impression material and trays. It makes copies of the teeth that can be compared later. It may be hard to use in young children because of gagging.

History and Questionnaire Kit

This type contains forms about reflux symptoms, vomiting, food and drink habits, medicines, and brushing. It helps identify possible causes of acid exposure.

Combined (Complete) Kit

This type merges the scoring, saliva, photography, and history components in one package. It suits specialist clinics that follow children over time.

Research-Grade Measurement Kit

This type uses digital 3D scanning or laboratory surface measurement to detect very small changes. It is mainly used in studies, not in routine care.

Kit Type	Main Purpose	Usual Age Range	Typical Setting	Training Needed
Basic clinical scoring	Record extent and location of wear	Any age with teeth	Clinics, schools	Basic dental training
Saliva testing	Measure protection against acid	Easier from early school age; adapted methods for younger children	Clinics, research centers	Trained staff
Photographic and imaging	Visual record over time	Any age able to cooperate	Clinics	Basic camera skills
Impression and study model	Make models for comparison	Usually older children	Dental clinics	Dental training
History and questionnaire	Find possible acid sources	Any age, with caregiver help	Any setting	Little training
Combined	Full assessment	As for each part	Specialist clinics	Trained staff
Research-grade	Measure very small changes	Mostly older children in studies	Research centers	Specialist training

Parts and Components of a Dental Erosion Assessment Kit

Exact contents differ between kits. The common parts are listed below.

Mouth Mirror and Retractors

The mirror allows a clear view of the tongue-side and back surfaces of teeth. Retractors gently hold the lips and cheeks away. Good visibility is needed to score every region correctly.

Blunt Probe

Some kits include a blunt-tipped instrument. It is used to point at surfaces or lightly check texture. Firm pressure is avoided, because acid-affected surfaces may be soft and sensitive.

Scoring Chart and Recording Sheet

The chart explains each score, often from 0 to 3. The sheet stores scores, saliva results, and notes. Using the same chart every time keeps records consistent.

Saliva Collection Set

This includes cups or graduated tubes, stimulation material, and a timer. Saliva volume divided by collection time gives the flow rate. Flow rate matters because saliva is the main natural defense against acid.

pH and Buffer Test Strips

pH strips change color to show how acidic the saliva is. Buffer strips show how well saliva can neutralize acid. Each strip is read against a color chart within a set time.

Camera and Photography Accessories

These include an intraoral camera or camera, cheek retractors, and sometimes contrast backgrounds. Standard photos taken from the same angles allow later comparison.

Impression Material and Trays

These are optional. Silicone material takes a copy of the teeth. Models made from it can be compared over months or years.

Questionnaires and Diet Diary

These forms collect information on reflux symptoms, vomiting, drinks, snacks, medicines, and brushing habits. They help link the findings in the mouth to possible causes.

Protective and Cleaning Supplies

Gloves, masks, gauze, cotton rolls, bibs, and disposal bags support hygiene. They reduce the risk of infection spreading between children.

Component	Main Function	Reusable or Single-Use	Typical Replacement Interval
Mouth mirror	Viewing hidden surfaces	Reusable	When scratched, cloudy, loose, or damaged
Cheek and lip retractors	Holding soft tissue away	Reusable or disposable	When cracked, warped, or after each use if disposable
Blunt probe	Pointing and light texture check	Reusable	When the tip is bent or damaged
Scoring chart and recording sheets	Scoring and record keeping	Chart reusable; sheets single-use	Chart when worn or outdated; sheets after each child
Saliva cups and tubes	Collecting and measuring saliva	Single-use	After each use
Stimulation material	Encouraging saliva flow	Single-use	After each use
pH and buffer strips	Estimating acidity and buffering	Single-use	After each test; discard at expiry or if exposed to moisture
Camera	Photographic record	Reusable	Per manufacturer; protective sleeves after each use
Impression material	Copying tooth surfaces	Single-use	After each use; check expiry date
Gloves and masks	Infection control	Single-use	For each child

How a Dental Erosion Assessment Kit Works

The kit works by looking at three linked areas: the damage, the defense, and the cause.

The damage. Teeth lose minerals when the acidity in the mouth rises above a critical level. For enamel, this point is often given as about pH 5.5. (On the pH scale, lower numbers mean stronger acid.) Stomach acid usually has a very low pH, roughly between 1 and 3.

Enamel softens first, and repeated exposure can remove the softened surface bit by bit. The scoring chart records this loss.

The defense. Saliva protects teeth in three ways. It washes acid away, it neutralizes acid with natural buffers, and it supplies calcium and phosphate that can help harden softened enamel again. A low saliva flow or weak buffering gives less protection. The saliva tests measure flow, pH, and buffering.

The cause. The history forms look for sources of acid, such as reflux symptoms, vomiting, acidic drinks, sour foods, and some medicines. The location of wear can give clues. Reflux acid may affect the tongue-side surfaces of the upper teeth and the chewing surfaces of the back teeth. Acidic drinks may also affect the outer surfaces of the front teeth.

These patterns are guides only, not proof.

Combining the three areas gives a fuller picture than any single test.

Step-by-Step User Guide for Dental Erosion Assessment in Children

Prepare the kit and workspace. All items are checked for completeness, cleanliness, and expiry dates. The manufacturer instructions for the exact kit are read. A clean surface and good lighting are arranged.
Explain the process to the child. A short explanation in simple words helps the child know what to expect. The mirror and collection cup are shown first. Consent from the parent or legal guardian and agreement from the child are obtained.
Take the history. Questions cover reflux symptoms (heartburn, sour taste, bringing up food), vomiting, night-time symptoms, medicines, drinks, snacks, brushing habits, and tooth sensitivity. Answers are written on the recording sheet.
Collect saliva before food or brushing. Saliva is usually collected before the mouth examination, after a period without food, drinks other than water, or tooth brushing. This period is often about one to two hours, but the kit instructions set the exact time. The child sits quietly or chews the stimulation material, and saliva is collected for a set time, commonly around five minutes.
Measure the saliva. The volume is read from the tube and divided by the minutes to give a flow rate in milliliters per minute. A pH strip is placed in fresh saliva and read against the color chart at the stated time. Buffer strips are used as the instructions describe.
Examine the teeth. Teeth are gently dried with gauze and checked with the mirror under good light. All six mouth regions (called sextants) are inspected. Notes are made of shiny or smooth surfaces, rounded dips on chewing surfaces, thin tooth edges, fillings standing above the tooth surface, and yellowish areas of exposed dentin.
Score the wear. Using the chart, the most affected surface in each region receives a score from 0 to 3. The six scores are added to give a total. For baby teeth, some kits use adjusted rules that are described in their instructions.
Take photographs or impressions if included. Baseline photographs of upper and lower teeth are taken from the same angles each time. These help show changes that are hard to notice by eye.
Record, explain, and plan follow-up. Scores, saliva values, photographs, and history are stored together. Findings are explained in simple words. A plan is made for prevention, monitoring, and medical review when reflux symptoms need evaluation.

Note: A child who is anxious or unable to cooperate may complete only part of the assessment. Trained operators are needed for consistent scoring. Manufacturer instructions take priority over any general description. Results are best interpreted together with the full dental and medical picture.

Precautions and Possible Dangers of Dental Erosion Assessment

The kit cannot confirm or rule out GERD. Assuming all wear comes from reflux may delay finding other causes.
Allergies to latex gloves, wax, or flavorings are possible. Allergy history is checked first.
Small parts, wax, and gum are choking risks in young children. Age-appropriate methods are chosen.
Children with swallowing problems, weak muscle control, or reduced alertness face a higher risk of saliva entering the airway. These children need safe positioning and may need saliva collection by suction or swab instead of spitting.
Gagging can occur with retractors, trays, and impression material. Impression steps may be skipped in young or sensitive children.
Eroded teeth may be sensitive. Strong air blasts, cold water, and firm instrument pressure are avoided.
Reusable instruments must be cleaned and sterilized between children. Single-use items are discarded after one use.
Saliva is handled as a body fluid, with gloves and standard infection control steps.
Test strips and chemicals are not for swallowing and are stored out of reach of children.
Saliva results can be unreliable if the child recently ate, drank, brushed, or chewed gum. Illness, dehydration, and some medicines that dry the mouth may also change results.
One assessment is a single snapshot. A single result should not decide treatment alone.
Photographs and records are personal health data. Consent and secure storage are needed.

Warning: A dental assessment must not replace medical care for reflux. Urgent medical attention is needed for green or bloody vomit, forceful (projectile) vomiting in a young infant, trouble breathing or repeated choking, refusal to feed with poor weight gain, pain or difficulty when swallowing, or blood in the stool or black stools.

Facial swelling, spreading gum swelling, or fever with tooth pain also need prompt dental or medical care.

How to Keep the Dental Erosion Assessment Kit Safe and Well Maintained

Cleaning and sterilizing: Reusable items are cleaned and then sterilized or disinfected between children using methods the manufacturer approves.
Single-use items: Cups, strips, sleeves, and impression material are discarded after use and never reused.
Storage of strips: Strips stay in their sealed original container in a cool, dry place away from sunlight and moisture. The test pads are not touched. The date of opening is noted, and strips are discarded at expiry.
Storage of other materials: Impression materials and other consumables are stored as their labels state.
Calibration: If the kit includes a digital pH meter or scale, it is calibrated regularly with standard solutions as the manual directs. Graduated tubes are checked for readable markings.
Color charts: Charts can fade with light exposure and are replaced when faded. Strips are read in the same lighting each time.
Servicing: Cameras, lights, and cables are inspected regularly. Lenses are cleaned with recommended wipes.
Data management: Images and scores are stored with protected child identifiers, limited access, and retention periods that follow local rules.
Software updates: Camera or record software is updated after checking compatibility, and data is backed up first.
Backup plan: Spare strips, retractors, and cups are kept on hand. Records are copied to a second secure location. Paper recording sheets are available if a device fails.
Stock checks: Contents are checked against the inventory list on a regular schedule.

Interactive FAQ: Dental Erosion Assessment Kit and Reflux in Children

Is a dental erosion assessment kit safe for children and babies?

It is generally considered safe when trained people use age-appropriate methods. The assessment is non-invasive and does not use radiation. Small risks include gagging, choking on small items, and allergic reactions to gloves or wax. Babies and toddlers usually have a simple visual check without saliva collection by spitting.

How long does a dental erosion assessment take?

A basic scoring check may take roughly 5 to 10 minutes. Saliva collection often adds another 10 to 15 minutes, because collection times are commonly about 5 minutes each. History taking and photographs add more time. A full session may take around 30 to 45 minutes, depending on the kit and the child's cooperation.

What are the different types of dental erosion assessment kits?

Main types include basic clinical scoring kits, saliva testing kits, photographic kits, impression kits, questionnaire kits, and combined kits. Research centers also use digital scanning tools. Kit contents differ between manufacturers, so the contents list should always be checked.

Does the kit involve radiation, and is it invasive?

The standard kit does not use radiation and is not invasive. It involves looking at the teeth, using a small mirror, and collecting saliva. Dental X-rays are separate and are used only when a dentist judges them necessary, for example to look for cavities.

Can a dental erosion assessment kit diagnose GERD?

No. The kit can show acid-related tooth wear and record how severe it is. It cannot prove that the acid came from the stomach. Diagnosing GERD needs a medical assessment, which may include symptom history, a trial of treatment, and in some cases tests such as pH-impedance monitoring or endoscopy.

What does the child feel during the assessment?

Most children feel a mirror and a light in the mouth, cheek stretchers if photographs are taken, and chewing on wax or sitting quietly to collect saliva. Eroded teeth may feel sensitive to air or cold. Gagging can happen with trays or impression material.

How is it different from a routine dental check-up?

A routine check-up looks at many things, such as cavities and gum health, and may note tooth wear only briefly. The kit adds a structured wear score, saliva measurements, and standard photographs, so changes can be compared over time. The kit can also be built into a routine check-up.

Who typically operates a dental erosion assessment kit?

Dentists, pediatric dentists, and trained dental team members usually carry out the assessment. Trained doctors or nurses may take the history, do a basic mouth inspection, or collect saliva. Research staff use the kit in studies. Training matters, because consistent scoring depends on it.

How accurate is a dental erosion assessment kit compared to other methods?

Visual scoring systems are simple and may give repeatable results when examiners are trained, but they depend on human judgment. Digital scanning and laboratory surface measurement can detect smaller changes, though they are mostly used in research. Saliva strips give quick estimates, while laboratory analysis is more precise. The kit is less accurate at finding the cause, because several causes produce similar wear.

Can the kit be used with braces, crowns, sealants, or medical conditions?

Yes, with adjustments. Braces, crowns, fillings, and sealants can hide or cover surfaces, so only visible natural tooth surfaces are scored. Children with cerebral palsy, developmental disabilities, or swallowing problems may need adapted saliva collection and careful positioning. Mouth sores, very dry mouth, or loose teeth may limit some steps.

How often should the assessment be repeated?

There is no single rule. A baseline is recorded first. Repeat checks are often planned about every 6 to 12 months when wear is moderate or high or when reflux is active, and less often when little or no wear is found. Photographs at each visit make comparison easier.

What happens if the child is uncooperative or anxious?

Steps can be delayed, split across several visits, or skipped. Explaining what will happen, showing the tools first, and using short, calm instructions may help. Steps that need the most cooperation, such as spitting saliva or taking impressions, are usually left until last or left out. A basic visual check is often enough at the first visit.

Can dental erosion caused by reflux be reversed?

Lost tooth tissue does not grow back. Very early softening of the enamel surface can partly harden again when acid exposure falls, and saliva and fluoride help this process. Established loss can be protected with preventive care and, if needed, dental restorations. Controlling the acid source is a key step and is decided by dental and medical professionals.

Other Methods and Alternatives to a Dental Erosion Assessment Kit

Several other methods examine tooth wear or reflux. Some are used together with the kit.

Method	Basic Principle	Common Use
Dental erosion assessment kit (this device)	Combines wear scoring, saliva tests, photographs, and history	Assessing and monitoring acid-related tooth wear in children
Visual scoring alone (BEWE-type)	Scores six mouth regions from 0 to 3	Quick screening and record keeping
General tooth wear index	Scores individual tooth surfaces by wear depth	Recording all types of tooth wear
Clinical photographs	Standard images taken at each visit	Visual monitoring over time
Study models	Copies of the teeth compared later	Long-term tracking of wear
Intraoral 3D scanner	Digital surface maps compared between visits	Detailed monitoring in specialist clinics and research
Laboratory surface measurement	Measures tiny height changes on tooth surfaces or models	Research studies
Saliva tests alone	Flow, pH, and buffering measurements	Assessing protection against acid
Food and drink diary	Lists what is eaten and drunk and when	Finding acid from diet
Esophageal pH-impedance monitoring	A thin sensor in the food pipe records reflux events	Medical diagnosis of reflux; does not assess teeth
Upper endoscopy	A small camera checks the lining of the food pipe and stomach	Looking for reflux complications
Saliva pepsin testing	Looks for a stomach enzyme in saliva	Under study as a possible reflux marker; not a standard test on its own

Frequently Overlooked Points Worth Knowing About Reflux and Tooth Erosion

Erosion, attrition (wear from tooth contact), and abrasion (wear from outside objects such as hard brushing) can look alike. More than one may be present in the same child.
Erosion may be present without pain or obvious change in tooth color, especially at early stages.
Reflux can occur without much heartburn or vomiting. Some children have few or no obvious symptoms.
Night-time reflux may be more harmful to teeth, because saliva flow and swallowing drop during sleep.
The frequency of acid contact often matters more than the amount. Frequent sipping of acidic drinks can be as harmful as a large single serving.
Foods and drinks seen as healthy, such as fruit juices, citrus fruits, and some flavored waters, can still be acidic.
Some liquid medicines are acidic or sugary, and some medicines reduce saliva flow.
Brushing straight after acid exposure may remove softened enamel. Waiting before brushing, and rinsing with plain water, are commonly advised. A fluoride rinse may help in children old enough to spit it out.
Treatment of reflux does not always remove other acid sources. The diet may still play a role.
Baby teeth have thinner enamel, so wear may reach the dentin sooner than in permanent teeth.
Saliva flow varies with time of day, hydration, mood, and recent activity. A single reading may not represent the usual level.
A single assessment shows the current state only. Repeated assessments show whether wear is progressing.

How to Read and Understand Dental Erosion Assessment Results

Result Parameter	What It Means
Sextant score (0 to 3)	Level of wear in each of six regions. 0 means no erosive wear. 1 means initial loss of surface texture. 2 means a distinct defect with tissue loss on less than half of the surface. 3 means tissue loss on half or more of the surface.
Total BEWE-type score	The sum of six sextant scores, from 0 to 18. Higher totals suggest more widespread or deeper wear.
Pattern of affected surfaces	Wear on tongue-side surfaces of upper teeth and on chewing surfaces may fit stomach acid. Wear on outer surfaces may fit acidic drinks. The pattern is a clue only.
Dentin exposure	Yellowish or darker patches show that enamel has worn through. Dentin wears faster than enamel and may cause sensitivity.
Resting (unstimulated) saliva flow	Flow without chewing or other stimulation. Very low flow gives less protection. In adults, values below about 0.1 mL per minute are often called very low. Values in children vary.
Stimulated saliva flow	Flow during chewing or other stimulation. In adults, about 1 mL per minute or more is commonly seen as normal, and below about 0.7 mL per minute as low. Children's values vary with age.
Saliva pH	Resting saliva is usually near neutral, roughly between pH 6 and 7.5. Lower readings suggest more acid in the mouth. Recent food, drinks, or reflux can shift a single reading.
Buffer capacity	Reported as high, medium, or low, often by color score. Low means a weaker ability to neutralize acid.
Reflux and diet history	Shows how often acid reaches the mouth from the stomach or from food and drinks.
Change over time	Comparison of scores and photographs between visits. Stable results and progressing wear lead to different follow-up plans.

Note: Reference values vary by age, sex, population, and the exact kit used. The numbers above are general guides, not clinical cutoffs. A trained professional interprets results together with the full history and examination.

General Guide to Total Score Levels

The original BEWE guidance, developed mainly with adults, groups total scores into risk levels. Children may be reviewed sooner, and the clinician decides the plan.

Total Score	Commonly Used Level	General Approach in the Guidance
0 to 2	None	Routine observation, with re-checks at longer intervals (about 3 years in the original guidance)
3 to 8	Low	Advice on oral hygiene and diet, observation, re-checks at longer intervals
9 to 13	Medium	Find and reduce causes, use measures that strengthen tooth surfaces, avoid restorations if possible, monitor with photographs or models, re-check about every 6 to 12 months
14 and above	High	As for medium, and consider restorative treatment if wear progresses quickly; re-check about every 6 to 12 months

Strip results seem unexpected	Expired or damp strips, or food in the mouth	Check expiry dates, open a new pack, and repeat with a clean sample
Child gags	Mirror or tray touching the back of the mouth, or retractor pressure	Slow down, use smaller retractors, distract the child, or skip that step
Teeth hard to score	Plaque, food debris, or wet surfaces	Ask for a plain water rinse, then gently dry with gauze
Glare or shiny spots in photographs	Wet tooth surfaces and reflected light	Dry the teeth with gauze and adjust the angle of the camera
Photographs differ between visits	Different angles, distance, or lighting	Use a fixed set of views and settings, and write them in the record
Scores differ between examiners	Different interpretation of the chart	Train together on the same chart, and use the same examiner for follow-up when possible
Camera does not connect or images are blurry	Loose cable, dirty lens, low battery, or software fault	Check connections, clean the lens, charge the device, restart the software, and check the manual
Impression is distorted	Incorrect mixing or movement of the child	Repeat only if the child tolerates it; otherwise rely on photographs
Saliva pH looks normal but wear is severe	Acid exposure comes in episodes, so a resting reading may miss it	Interpret the result together with history, scoring, and other saliva tests

When to Contact the Manufacturer or Service Provider
