Survey on the Morphology and Pulp Cavities of the Mandibular First and Third Molars in Egyptian Population

Abstract

The study of dental morphological characteristics is important in research as it can provide information about diversities within a population. Studying the internal and external anatomy of the permanent teeth has been the main scope of many morphological and morphometric studies in different populations. Many studies have shown different trends in the shape and number of roots and canals among different races especially in molars. So, this study was conducted to understand the morphology and pulp cavity of the mandibular first (M1) and third (M3) molars in a sample of the Egyptian population. II- Materials and methods: 1) Occlusal morphology: a- Cusp number and groove pattern Examination of M1 and M3 was done on the study casts. A cusp was considered as a pronounced elevation on the occlusal surface of a tooth terminating in a conical, rounded or flat surface (Jordan et al., 1992).
