objective: taurodontism is a dental anomaly characterized by elongation of root body and apical displacement of the pulp chamber floor associated with shortening of roots and their narrowing at the cementoenamel junction (cej). due to having a dilated apical one-third, these teeth may cause complications during extraction, locating canal orifices and instrumentation. this study aimed to assess ...

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...

A fully bonded m~dtiloop wire appliance for the correction of ectopically erupting permanent molars is described. The appliance allows control in the anteroposterior, vertical, and transverse planes. Ectopically erupting first permanent molars are seen in about 3% of the population.~,2 Sixty-six per cent of ectopically erupting maxillary first permanent molars self-correct by jumping over the i...

BACKGROUND AND AIM: The first permanent molar is the first permanent tooth that erupted in 6-7-year-old and is very high risk for caries. Parent’s awareness has very important role in oral and dental health of children. The aim of this study was to assess the awareness of parents of 7-8-year-old children in Kerman about presence of the first permanent molar and concepts of preventive dentistry ...

A simple method of treating an ectopically erupting first permanent molar is presented which utilizes both a molar band with helical finger springs cemented to a second primary molar, and a curved tag of composite resin which is acid-etched to the occlusal surface of the affected first permanent molar. When activated and placed into proper position, the springs act at right angles to the long a...

The study investigates the gender predictability of permanent maxillary first molar teeth. Mesio distal width of 30 permanent maxillary first molar teeth from casts of 15 male and 15 female patients between the age group of 1725 were measured. Results showed that permanent maxillary first molar tooth exhibited sexual dimorphism but accuracy of gender predictability was only moderate.

Introduction: Permanent first molar is the most important unit in the chewing system. Ear-ly loss of first molars can significantly reduce chewing efficiency, increase overbite, lead to premature eruption of the permanent second and third molars, and displacement of adjacent teeth. The purpose of this study was to determine the associated factors of permanent first molar caries in 7-9 years old...

The study was a cross sectional observational study undertaken to evaluate the frequency of dental caries in mandibular first molar and its antimere in the opposite mandibular quadrant in eight to ten years old children seen at 28 Military Dental Centre. The study involved 100 male and 100 female children of age 6-10 Years. 80(80%) males exhibited evidence of simultaneous presence of dental car...
