The Tubercule Carabeli in a Moroccan Population

Abstract

Aim: The aim of our study was to determine the prevalence, degree of expression and the symmetry of the Tubercle of Carabelli “TC” in a sample of Dentistry students to highlight this sensitive area to dental caries. Materials and methods: We conducted a descriptive transversal survey of students in the 4th year of the academic year 2015/2016 at the Faculty of Dental Medicine of Casablanca. The study is made on plaster models, by measuring the mesiodistal diameter of the TC with an electronic caliper. Results: Several results were obtained: 64.29% of the study population have the CT, while it is absent in 35.71% of cases, 37.50% With a tubercle of Carabelli little developed, 26.71% With a well-developed Carabelli tubercle, 61.11% of cases exhibit TC bilaterally and 38.89% Of cases present the TC unilaterally. The results are consistent with those obtained in other surveys conducted in other countries. Conclusion: The lack of standardization of the study’s methodology makes it difficult to compare the results of various studies, hence the need for similar studies on larger samples. Clinical Significance: It has some importance in the dental, forensic, anthropological and dental industries. In orthodontics, the cause of premature caries and periodontal diseases, also in extractions, the molar extraction instruments have no housing for this cusp and can therefore lead to his fracture.
