PREVALENCE OF MIDDLE MESIAL CANALS IN THE MESIAL ROOT OF FIRST PERMANENT MANDIBULAR MOLARS IN EGYPTIAN POPULATION: AN INVIVO COHORT RETROSPECTIVE CONE-BEAM COMPUTED TOMOGRAPHIC STUDY

Prevalence of Middle Mesial Canals in Mandibular First Molars: an In-vivo CBCT

Morphological changes related to age in mesial root canals of permanent mandibular first molars.

The aim of this study was to evaluate age-related morphological canal changes in mesial root canals of mandibular first molars of known ages. Fifty-six specimens were selected for this study and distributed into the following four age groups (n. 14): a) Group of children under 13 years, b) Group of adolescents (from 14 to 19 years), c) Group of young adults (from 20 to 39 years) and d) Group of...

Independent and Confluent Middle Mesial Root Canals in Mandibular First Molars: A Report of Four Cases

Mandibular molars demonstrate considerable variations with respect to number of roots and root canals. The possibility of additional root canals should be considered even in teeth with a low frequency of abnormal root canal anatomy. This paper discusses the endodontic management of the rare anatomical complexity middle mesial canals in mandibular first molar and also serves to remind the clinic...

Micro-computed tomography study of the internal anatomy of mesial root canals of mandibular molars.

INTRODUCTION The aim of this study was to determine the mesiodistal and buccolingual diameter, apical volume, and the presence of isthmuses at the apical level of mesial root canals of mandibular molars. METHODS Sixty extracted first and second mandibular molars were scanned by using a SkyScan 1076 micro-computed tomography system with a voxel size of 18 μm. The apical thirds of the samples w...

Prevalence of Mid-Mesial Canal and Isthmuses in Mandibular First and Second Molars in an Iranian Population

Background and Aim: It is essential to know the internal root canal anatomy to reach a successful root canal debridement and a subsequent successful root canal obturation. Due to the importance of knowing the complexity of mid-mesial (MM) canals and isthmuses and how to deal with these anatomic variations, in this study, we examined the incidence and prevalence of the MM canal and isthmuses in ...
