Considering that the second inferior molar is a tooth of large anatomic variation, we have proposed ourselves to anatyse some aspects of the internal and external morphology of its roots. The external morphology, 67,64% was visually evaluea, gathering the teet with differentiated, fused or single roots. The internal morphology was examinea after wear of mesial and distal roots to altow examination in the mesiodistalginge. One hundred and two teeth have been examined. As for the external morphology we found that 75,49% show differentiated roots, 18,62% fused roors and 5188% single roots. As for

The mandibular third molar poses a challenge to dental surgeons due to it’s unpredictable morphology which leads to increased difficulty during its extraction. The root morphology of the third molar is considered to be the most variable in the human dentition. The study aims to document these variations which will be useful while undertaking procedures on the third molar. Three hundred and fifty nine panoramic views of the mandible were obtained from the Radiology division for patients seeking treatment in the School of Dental Sciences since 2010.

ABSTRACT The main goal of endodontic treatment is healing of the periapical tissues which are gained by elimination of bacteria and their byproducts from the canal and prevention from reinfection. Understanding of root canal anatomy is an essential part in endodontic treatment. Anatomic forms and variations in special teeth should be well known, one of them is extra roots/ canals. Although possible aberrations of canal anatomy should be considered for all teeth, some teeth should be highlighted. This review addresses the prevalence, diagnosis (clinical and radiographic), and endodontic managem

Materials and Methods: Hundred teeth each comprising of first, second, and third molars collected from different dental schools and clinics in India were subjected to standard dye penetration, decalcification and clearing procedure before being studied. Results: The first molar mesiobuccal roots exhibited 69% Type I, 24% Type II, 4% Type IV, 2% Type V, and 1% exhibited a Vertuccis Type VIII canal anatomy.

A meticulous knowledge of the root canal anatomy and morphology of the teeth is imperative to achieve successful root canal and also many other dental and surgical treatments on them. The purpose of this study was to study the root canal anatomy and morphology of permanent maxillary Lateral incisors in Kerman. 100 extracted intact permanent maxillary Lateral incisor teeth were collected from different dental clinics in Kerman. The anatomic and morphologic characteristics of the selected samples such as the number of roots, the apical root curve direction and the length of the teeth were determ

This case report illustrates the teeth morphology of a chimpanzee and its anatomical variations. A well-preserved skull of a male Pan troglodytes troglodyte chimpanzee was scanned using a cone-beam computed tomography machine. Measurements included tooth and crown height, root length, root canal length and width (posterior teeth), and pulp cavity length (anterior teeth). Nonmetrical parameters included number of canals and foramina per root of every root. Interestingly, the mandibular central incisor was longer than the lateral incisor, and all the mandibular anterior teeth presented with a so

The roots of 130 extracted teeth were examined for non-apical ramifications from the main canal. Following decalcification and dehydration, the root canals were identified with an Indian ink gel. Secondary canals were found in 4 of the 130 teeth (2.4%), and stumps that may represent incomplete lateral canals were identified in two teeth. We conclude that non-apical root canal ramifications are much less common in dogs compared to humans.

The occurrence of root resorption in orthodontically treated permanent incisors with partially formed roots was investigated using periapical radiographs taken before and after the orthodontic leveling in the mixed dentition. The mean age at the beginning of treatment was 9 years and the mean treatment time was 7.1 months. The findings showed that the orthodontic movement during root formation causes no root resorption. The longitudinal follow-up showed that incompletely formed roots developed normally.
