A comparison of senior dental students and normative standards with regard to caries assessment and treatment decisions to restore occlusal surfaces of permanent teeth

Aim: The aim of this study was to evaluate caries diagnosis and treatment decisions made by undergraduate dental students based on ICDAS or Nyvad criteria. Methods: Twelve students analyzed 90 digital photographs of permanent teeth at different clinical stages of carious lesion development and chose among different treatments in three different assessments: when there was no knowledge of the criteria (described as “No knowledge (N)”; when there was theoretical knowledge of the criteria (described as “Theoretical knowledge (T)” and when there was theoretical knowledge, clinical experience about dental caries and the criteria (described as “Theoretical and clinical knowledge (TC)”. For “T” and “TC” the students were randomized into two experimental groups – ICDAS or Nyvad (experimental units: 6 students/group). The reference standard was established cooperatively by two experienced researchers. Criteria performance was evaluated by sensitivity, specificity, AUC, and Kappa statistics. Treatment decision was described in percentage by contingency tables and Spearman’s correlation with the reference standard. Results: The first assessment demonstrated a high percentage of operative treatment even for initial enamel lesions based on ICDAS criteria and treatment was proposed for both active and inactive lesions, according to the Nyvad criteria. In the second assessment, the students continued recommending treatments for initial or inactive lesions, but less frequently. In the third assessment, treatment decisions presented greater cohesion in relation to the assigned classification criterion. The criteria presented no differences between them in terms of diagnostic in the third assessment. Conclusion: Clinical experience may improve caries detection and treatment decisions with the use of ICDAS and Nyvad criteria.

Abstract Background The concept of minimal intervention dentistry (MID) includes both delayed restorative treatment and conservative caries removal, and is now recognised as an evidence-based approach for dental caries management. In order to determine if dental professionals in Russia are incorporating this concept into their clinical practice, we investigated the restorative treatment decisions of Russian dentists and dental students, and the factors associated with these decisions. Methods We included 171 general dental practitioners and dental therapists (collectively referred to here as “dentists”) from North-West Russia, and 76 dental undergraduate students from the Northern State Medical University in Arkhangelsk (response rate of 11.5% and 67.9%, respectively). Participants completed a questionnaire, which collected background information (sex, region of work, place of dental school graduation, practice type, years of working experience, working in an urban or rural area, and specialisation in restorative dentistry) and information on restorative treatment decisions for proximal and occlusal carious lesions of permanent teeth. Treatment options in accordance with MID were defined as intervention at dentin level and minimally invasive cavity preparation. Multinomial logistic regression was used for statistical analysis. Results For the proximal carious lesion, 9.4% of participants said they would employ both MID treatment options; 60.7% said they would choose only one; and 29.9% said they would use neither option. For the occlusal carious lesion, the corresponding figures were 37.2%, 52.1%, and 10.7%. No differences in restorative treatment options were observed among general dental practitioners, dental therapists, and dental students. For the proximal carious lesion, dentists from regions outside Arkhangelsk had 4.15 (95% confidence interval [CI] 1.13–15.27) times higher odds of following one versus both MID treatment options. For the occlusal carious lesion, working experience above 15 years was associated with higher odds of using only one versus both MID treatment options (adjusted odds ratio = 3.04, 95% CI 1.33–6.91). Almost all respondents preferred tooth-coloured materials for restorations; more than 75% chose resin-based composite. Conclusions The majority of Russian dentists and dental students do not apply the MID concept when treating dental caries in permanent teeth. Clinical protocols on dental caries treatment and dental school curriculums should be updated to place an enhanced focus on evidence-based practice and preventive strategies. Further studies with larger samples of Russian dentists and dental students and alternative methods of recruitment are needed to validate our results.

Dental Anatomy

The purpose of this report is to present educational material that would allow the dental student to learn to easily identify the morphologic characteristics of permanent teeth, and how they fit together (occlusion). In order to do this, macro models of permanent teeth with no attrition were carved in wax and later molded with alginate. These molds were filled with plaster, dental stone and/or cold-cured acrylic resin. The large individual dental stone tooth models were mounted on a wax base, thus obtaining maxillary and mandibular arches which were occluded. These dental arches were molded with plaster or dental stone. The authors suggest that these types of macro models allow an excellent visualization of the morphologic characteristics of permanent teeth and occlusion. Dental students are able to carve the permanent dentition in wax with great facility when they can observe macro models.

Abstract Objectives The aim of this study is to investigate the current knowledge and attitude of deep caries removal method among dental students in Malaysia. Materials and Methods A total of 303 students (n = 303) responded to the online questionnaire. The first part of questionnaire was to evaluate the demographic data of the respondents and focused on the technique and management approach used for deep caries lesion. The second part investigated the preferred treatment used for deep caries based on the designated clinical case, while the third part assessed the factors that affected the decision on deep caries management. Statistical Analysis Independent t-test was used to compare difference between the two groups. Results Seventy four percent of the students have the knowledge of the different methods of caries removal, while 25.8% were only familiar with complete caries removal. The preferred method for deep caries removal in permanent teeth was partial caries removal (53%). For primary dentition, 45.6% of the students prefer to perform pulpotomy as compared with other techniques. There was no significant difference in caries removal method for permanent teeth between undergraduate year of study (p > 0.05), which was partial caries removal at 52.7 and 53.5%, respectively. For primary dentition, the preferred caries removal method was pulpotomy for year 4 (39.8%) and year 5 (52%) students. The popular material to restore deep caries was resin composite (42%) followed by glass ionomer cement (23.3%). Conclusions This study showed that partial caries removal was the preferred method despite partial understanding on the identification of the clinical indicators of the technique.

Relevant Family History

Non-syndromic oligodontia, the agenesis of six or more teeth, has a prevalence of 0.14–0.25%. Genetic, epigenetic and environmental influences affect expression. Three brothers presented with agenesis of 14, 21 and 23 permanent teeth, respectively. They were medically well, with no relevant family history. Each case presented with caries, microdontia and attritive tooth surface loss. Comprehensive care was delivered in each case by undergraduate dental students. Individualized prevention and stabilization were completed before referral for multidisciplinary long-term planning. Primary dental care practitioners are instrumental in delivering preventive care and stabilizing the dentition in cases of dental anomaly, while sharing care with specialist teams. CPD/Clinical Relevance: An unusual presentation of non-syndromic oligodontia relevant to primary dental care practitioners who are likely to provide the first clinical contact and referral to the wider multidisciplinary team.

Background: Universal tooth numbering system is an old topic of oral anatomy course. MICAP is a new tooth notation but it is not yet in dental curriculum. Aim: To compare the learning of MICAP (new) vs Universal (old) tooth notations using lecture method. Method: Designs: A pre-test and post-test design. Settings: Islamic International Dental College – Islamabad. Period: October 2016 to February 2017. Participants: Novice undergraduate first year dental students (N=45) participated in the study. They were randomly divided into two groups. Interventions: MICAP and Universal tooth notations were taught to group A and B respectively by a 30 minute lecture prepared on power point slides in similar sequence. The study participants, before any intervention, completed fourteen randomly selected permanent teeth using Universal and MICAP notation method as pretest data and after eight weeks, posttest data were collected. Chi square test was applied for analysis. Results: The posttest showed an improved learning of two notations by both groups. Over all, no significant difference was found in correct write up of given set of fourteen teeth for two notations except ‘Maxillary right central incisor, Mandibular left canine’ and Mandibular Right 2nd Premolar (p< 0.05). Conclusion: Learning of new (MICAP) notation was as easy as the old (Universal) numbering system. However, this was a small scale study and multiple teaching centers with larger number of participants are recommended.

The Individual

This paper provides recommendations for dentists for the treatment of dental caries in children, with an emphasis on early childhood caries (ECC), primary teeth, and occlusal surfaces in permanent teeth. A consensus workshop followed by an e-Delphi consensus process was conducted with an expert panel nominated by the European Organization for Caries Research (ORCA) and European Federation of Conservative Dentistry (EFCD)/German Association of Conservative Dentistry (DGZ) boards. Based on 3 systematic reviews and a nonsystematic literature search, recommendations were developed. The caries decline has led to a more polarized disease distribution in children and adolescents along social gradients which should be taken into account when managing the caries process at all levels, such as the individual, the group, or a population. The control or reduction of caries activity is the basis for successful caries management. In children, caries management requires adequate daily oral hygiene and fluoride application via toothpaste, ensured by caregivers, and especially for ECC prevention an emphasis on sugar intake reduction is needed. These noninvasive interventions are also suitable to arrest or control initial or even cavitated dentine caries lesions in the absence of irreversible pulpitis. Fluoride varnish or silver diammine fluoride can be added as supplementary agents. In pits and fissures, composite resin materials can be used as preventive sealants and for defect-oriented minimally invasive restorations. In primary molars, preformed metal crowns are more successful than multisurface fillings, especially in caries-active patients. With persisting high caries activity, multiple lesions, and limited cooperation, caries control should consist of robust measures with high success rates, even including extraction in selected cases. This applies especially to treatments performed under general anesthesia.
