CPD information

Where this course can count

In the United Kingdom, Ireland and Australia, the dental regulators do not vet CPD courses or providers. Each dentist decides whether an activity meets their requirements, and the regulators say so in their own words:

United Kingdom

26 hours of verifiable CPD, GDC development outcome C. The certificate carries each of the seven details the GDC asks providers to put on CPD evidence, listed under What your certificate shows.

Ireland

26 hours of structured CPD. The course meets the four criteria the Dental Council of Ireland sets for structured CPD: concise educational aims and objectives, clear anticipated outcomes, quality controls that include a formal opportunity for participants to provide feedback, and documentary proof of attendance from the course organiser. Separately, the Council's guide states that “activities that meet the criteria for structured CPD can be recorded as such, regardless of location.”

Australia

26 hours of clinically or scientifically based CPD, self-assessed against the Dental Board of Australia CPD guidelines.

New Zealand

Suitable as a professional development activity (PDA) for your Dental Council NZ recertification programme. The Council sets no quota of PDA hours.

Ontario

Eligible for RCDSO Category 3 CE points (self-reported). Category 3 counts for up to 30 of the 90 points in each three-year cycle.

British Columbia

Supports your BCCOHP CPD. Since April 2026, the College no longer sets a required number of hours.

Other Canadian provinces

Rules differ. Some count a course like this one in a limited category, and some count only courses from sponsors the provincial regulator recognizes. Check with yours before you rely on this course.

United States

This course does not currently count toward US state board requirements. We are working on validating it for them.

Other countries

Check your regulator's rules for online courses before you rely on this one.

Regulators can change their rules. This page describes them as of the date at the top.

How you get your certificate

Hotmart, the course platform, issues the certificate from the Certificate button in your course area. The button works once you have done these four things:

1. Finish every lesson in the course area, including Module 0 at the start and the final module, CPD: Feedback and Certificate. The certificate stays locked until every one of them is finished.
2. Pass the quiz at the end of Modules 1, 2 and 3 with at least 70%. You can retake a quiz as often as you need, and we don't show the correct answers.
3. In the final module, fill in the written feedback form (a Google form), then work through the reflection lesson. Its questions are the GDC's own, ready to copy into your CPD activity log.
4. Click Certificate. The first time, the platform asks for the name to print on it. Type your full name as it appears on your registration, because it can't be changed afterwards.

Stopped part-way? Email guilhermecabraldossantos@gmail.com and we'll send you a record of the modules you completed, with only their hours. A module counts once every lesson in it is finished and its quiz is passed. That follows GDC guidance, under which a professional is “credited only for the number of hours they were in attendance”.

What your certificate shows

One page, in English, with:

• your name and the date you completed the course
• the subject, the course title and the format (online self-study)
• the total hours of CPD: 26, for all three modules
• the post-course assessment, marked as completed, with the pass mark of 70%
• the link to the references for each module
• GDC development outcome C
• short versions of the aims and the objectives, and a summary of the learning content
• the CPD type (clinically or scientifically based) and the four criteria for structured CPD
• the provider, the author and a contact email
• our confirmation that the information is full and accurate and that the CPD has been subject to quality assurance by Dr Guilherme Ricardo Cabral dos Santos

To check that a certificate is genuine, email guilhermecabraldossantos@gmail.com with the participant's name and completion date.

How the hours are counted

The course platform reports 26 hours of lesson content. We split them by module from the length of each module's lessons, rounded down to whole hours. Breaks are not counted.

We recalculate whenever a lesson is added, removed or re-recorded. You are credited only for the modules you complete.

Aims

To give general dental practitioners a structured way to recognize, name, stage and manage non-carious disease, the tooth wear produced by tension, biocorrosion (erosion) and friction. The course works from the mechanism that produces the wear and the patient who keeps it going, not from the visible lesion alone. It starts with the tools of diagnosis (naming, the five clinical signs, staging and the educational anamnesis). It then moves through the physics, the chemistry and the signature of each mechanism and the principles of managing it. It ends with the risk groups, the four axes (gastric, psychological, dietary and sleep) and how they intersect, and with how to prioritize the patient who carries more than one risk, including when and how to involve other health professionals.

Learning objectives

By the end of each module, the participant should be able to:

Module 1 · Foundations of Diagnosis

1. Name a non-carious lesion by location first, then by the mechanisms the findings can support (tension, biocorrosion and friction, the last including attrition and abrasion), without using “abfraction” as the name of a lesion; and match the course term biocorrosion to “erosive tooth wear” in the international literature.
2. Check every patient for the five clinical signs (dentin hypersensitivity, cracks, gingival recession, non-carious lesions and pulpal damage), count how many are present, and explain why the absence of sensitivity is not a sign of health.
3. Sort anamnesis findings into stimulus (what happens) and adaptive capacity (what the system is), and relate the four axes (gastric, psychological, dietary and sleep) to the load the patient produces.
4. Stage the patient from 0 to 3 with one gate and three questions (reversibility, consequence and activity); record a successful treatment as “same stage, disease inactive”; and distinguish what the BEWE measures from what it recommends.
5. Conduct and record the educational anamnesis (the opening, the question blocks, screening instruments when the patient has given a reason, an exam guided by hypotheses), and decide when to refer, to whom, and with what clinical information in the letter.

Module 2 · The Mechanisms of Action

1. Distinguish a mechanism (the verb: flexing, dissolving, wearing) from a lesion (the noun), describe the first signature of each of the three mechanisms, and explain why, acting together, they multiply rather than add up.
2. Explain how tension produces a cervical lesion (the elastic threshold, the five load factors, the direction of force, the tooth as a fixed beam, the wedge) and how it cracks a tooth; and assess a crack (transillumination, the enamel-dentin junction, direction and prognosis).
3. Explain biocorrosion as dissolution (the five chemical properties beyond pH, chelation, the salivary defense) and trace acid from outside the body (which acid, how often, how it enters the mouth and what state the saliva is in) and from within it (GERD and silent reflux, vomiting, sleep apnea).
4. Read the shape, texture and location of a cervical lesion to infer the agent (tension, acid or friction) and whether the lesion is active, and tell abrasion apart from attrition, including wear versus recession and why the toothbrush is often wrongly blamed.
5. Select management by mechanism (control of the etiological factor, means of prevention and restoration as a principle) and apply it to described clinical cases, explaining why restoring without controlling the cause leaves the process active.

Module 3 · Risk Groups

1. Count how many risk circles a patient falls into at the same time, explain why risk multiplies at the intersection, and set the order of care (stacking versus branching; which circle feeds the others and who can move each one; the lesion as a follow-up reading, not a target).
2. Screen the psychological, sleep, gastric and dietary axes with the instruments and criteria taught (for example GAD-7 and BAI, the Epworth and STOP-BANG, GerdQ and the Peptest, the food diary and salivary tests) and decide when to involve another professional, with the finding documented.
3. Tell bruxism (a behavior of central origin) apart from damage, explain why wear alone does not prove the behavior is active, and choose the appliance and the reassessment criterion for a patient with comorbidities (psychological plus sleep; apnea screened before any splint).
4. Distinguish, from the history, the conditions that produce the same palatal acid signature (emotional reflux, bulimia nervosa, purging anorexia nervosa, rumination syndrome, binge eating disorder), approach the patient without confronting them, and explain how night reflux, dry mouth and clenching add to one another's damage during sleep.
5. Explain why athletes and workers, young people who use substances, patients with systemic disease or polypharmacy or who have had radiotherapy, and post-orthodontic patients carry higher risk (a salivary defense that fails, exposure that does not let up, mineral that weakens, an amplifier of the three mechanisms), and choose the first lever of care in each group.

What each module covers

Module 1 · Foundations of Diagnosis · 4 hours

Learning content. Naming, the five clinical signs, adaptive capacity and the four axes, staging from 0 to 3, the educational anamnesis and referral.

Anticipated outcome. Participants name, count, stage and record non-carious disease in a standard way at the first appointment, and document what they refer to other professionals.

Module 2 · The Mechanisms of Action · 8 hours

Learning content. The physics, the chemistry and the signature of each mechanism, its triggers and its management, and how the three act together.

Anticipated outcome. For each non-carious lesion, participants record the mechanism (or combination) that its shape and location point to, and the triggers to investigate, before deciding on any restoration.

Module 3 · Risk Groups · 14 hours

Learning content. The risk groups: the psychological, sleep, gastric and dietary axes and where they intersect (bruxism, eating disorders, night reflux); athletes and workers; substances and young people; systemic disease, radiotherapy and polypharmacy; post-orthodontic patients; and how to prioritize the patient in several groups at once.

Anticipated outcome. Participants identify each patient's active axes and risk groups, document what supports each suspicion, and decide the order of referrals and care when more than one risk is present.

Before Module 1, an orientation module (Module 0) explains how the course and the certificate work. After Module 3, the final module, CPD: Feedback and Certificate, holds the feedback form and the reflection lesson. Neither adds CPD hours.

Development outcome

The course maps to GDC development outcome C: maintenance and development of knowledge and skill within your field of practice.

Quality assurance

Dr Guilherme Ricardo Cabral dos Santos is responsible for the quality assurance of the course. He wrote the course and presents it. He is a dentist practicing in Brazil, with a postgraduate specialization in restorative dentistry (Zenith, Florianópolis).

Before release. We cite every source by author and year, and each module links its reference list. We teach treatments and materials by category and mechanism, and name a brand only when a product can't be identified without it.

During the course. The platform records each finished lesson, and most quiz questions are short clinical cases.

After the course. Every participant gives written feedback. We read it in January and July, looking closely at objectives rated low, reports of commercial bias, statements flagged as unsupported or out of date, and disagreement with the stated hours. We check the whole course against current evidence at least every three years, and sooner if new evidence makes a lesson inaccurate. Each change gets a new course version number, and the top of this page shows the current one.

The full quality assurance statement is available on request from guilhermecabraldossantos@gmail.com.
