Primary double teeth (PDT), referring to either gemination or fusion, are one of the most important and frequent developmental dental anomalies that can affect children’s oral health. Many clinical complications are correlated with these anomalies, such as dental caries, malocclusions, periodontal problems, and dental anomalies in permanent dentition. The aim of this report was to describe, through two cases, a case of gemination and another of fusion, the clinical management, the consequent effects, and the possible repercussions of these two developmental abnormalities on permanent successors. The first case involved gemination of the primary maxillary left central incisor (#61) in a 6-year-old boy. The patient presented with dental caries in the geminated tooth and its contiguous primary left lateral incisor (#62). The radiological examination revealed a slight developmental delay in the permanent left lateral incisor (#22). The treatment plan involved performing a pulpotomy and restoring the dental crowns of the affected teeth. The second clinical case describes a 6-year-old girl with unilateral fusion between a primary mandibular lateral incisor (#72) and a supernumerary tooth (#72’). The treatment included restoration of the deep grooves of the fused teeth using flowable composite and coronal restoration of the contiguous left primary canine (#73). Clinical and radiological follow-ups were performed every 3 months to monitor the development of teeth. No clinical and radiological symptoms were noted during the follow-up visits. PDT may require a multidisciplinary treatment. They should be diagnosed early to avoid and treat any possible complications in both the primary teeth and their permanent successors.

Introduction. The educational program assessment has always been the main objective of quality improvement in all curricula. The aim of this study was to describe the levels of competency of final-year students of the Faculty of Dental Medicine of Monastir in Tunisia in the major skills needed for a new dentist. Methods. In this cross-sectional descriptive study, 154 students filled out a questionnaire including 53 competencies, rated on a four-point Likert scale, broadly based on the competencies described in the profile and competences for the graduating dentist in Europe. Results. The response rate was 67% (145/230). For twenty items in the questionnaire, over 75% of the students reported being competent. The five items with the highest percentages were “undertaking supragingival and subgingival scaling-Item 22” (97.2%), “evaluating the periodontium, establishing a diagnosis and formulating a treatment plan-Item 2” (96.6%), “identify the location and degree of activity of dental caries-Item 24 (95.9%), “taking and interpreting dental radiographs-Item 12” (94.4%), “restoring damaged teeth-Item 25” (93.8%), and “managing primary oral health care-Item 16” (93.8%). For eighteen skills, more than 75% of students self-rated being not competent, demonstrating a need of more thorough training, notably in periodontal surgery and implantology, among these, five skills were found that demand in-depth acquisition according to the students. Conclusion. The general state of competency of the last-year dental students was described as fairly satisfactory based on the students’ self-reported responses. However, theoretical and practical backgrounds related to some subjects in the school need to be improved.

Mesiodistal dimension of the pulp cavity is not proportional to that of the dental crown. Endodontic access cavity have to be shifted to the distal and vestibular sides from the first to the second upper molar.
