Morphometric analysis of developing crowns of maxillary primary second molars and permanent first molars in humans.
The purpose of this study was firstly to characterize the changes occurring in size and form of the mineralizing maxillary second primary molar and first permanent molar crowns, and secondly to determine if similar changes in size and form characterize enamel apposition in the crowns of these teeth. Twenty-five primary second molars and 20 maxillary permanent first molars at various stages of d...
متن کاملAssessment of Root Morphology and Apices of First and Second Maxillary Molars in Tehran Population
Introduction: Objective: This study aimed to assess the possible variations in root canal anatomy and topography of the apices of first and second maxillary molars. Materials and methods: A total of 67 first and second maxillary permanent molars were collected. Access cavity was prepared and 2% methylene blue was injected. The teeth were demineralized by 5% nitric acid and cleared with met...
متن کاملLocation of canal isthmus and accessory canals in the mesiobuccal root of maxillary first permanent molars.
BACKGROUND Failure in surgical endodontics may be caused by many factors. Failure is commonly due to improper preparation for the root-end filling and a lack of seal of the resected root end. The aim of this study was to investigate the morphology of resected mesiobuccal (MB) root ends of maxillary first molars and to evaluate the location of the canal isthmus and accessory canals between the M...
متن کاملInvestigation of the endodontic space in maxillary first permanent molars.
The purpose of the investigation was to establish the exact number of root canals in the maxillary first permanent molar, their direction, type and relation, based upon a large number of random samples. Randomly chosen 443 maxillary first permanent molars (221 left and 222 right) were investigated with the aim to get more knowledge into the morpho logy of the endodontic space. One canal in the...
متن کاملEffect of extraction of permanent first molars on the development and eruption of third molars
BACKGROUND AND AIM: It is required in many young patients that permanent first molars (PFMs) be extracted due to poor prognosis. This study investigates whether the extraction of such teeth is effective on the development of third molars and even their crown and root morphologies.METHODS: A total of 7000 panoramic radiographs were evaluated and 128 radiographs showing a history of extraction of...
