abstract : before initiating any endodontic therapy, probability of extra canals should be considered. the incidence of three canals in mandibular second premolar has been reported to be 0.46-0.5%. the present report describes nonsurgical endodontic treatment of three mandibular second premolars with three canals. in these cases, three orifices were located in mesiobuccal, distobuccal and lingu...

Introduction Age estimation holds significant importance within the realm of forensic science, serving as a crucial tool for various purposes such validating birth certificates, aiding immigration processes, and determining eligibility retirement benefits. Additionally, age carries implications in situations involving human trafficking, offering insights into matters legal culpability, adult cl...

presence of extra roots and canals should be considered before initiation of root canal treatment for the success of endodontic treatment. a mandibular second premolar with three separate roots is very rare and its prevalence has been reported to be around 0.1%. this case report explains non-surgical endodontic treatment of a mandibular second premolar with three separate roots and three separa...

Introduction: A large number of orthodontists prefer to rebond the failed bonded brackets or use recycled brackets in some instances. The aim of this study was to compare the shear bond strength of rebonding with using recycled brackets on enamel surface. Methods: Bonding of brackets on the surface of extracted first bicuspids was tested in five different groups to compare their shear bond stre...

This study aimed at evaluating measurements relative to the mesiodistal crown width and enamel thickness of maxillary first bicuspids. The sample consisted of 40 extracted sound bicuspids (20 right and 20 left), selected from white patients (mean age: 23.7 +/- 4.2 years), who were treated orthodontically with tooth extraction at a private clinic in São Paulo, SP, Brazil. All teeth were embedded...

A total of 263 ankyloscd primary molars in 107 children aged three to 12 years was studied for four years. Forty-six children remained in the study for eight years. Observation of affected dentitions showed that the condition was likely to recur. Three clinical pa~terns for the condition are described. Typically, maxillary molars became ankylosed earlier and demonstrated more severe in[raocclus...

Electron spin resonance (ESR) measurement data of 98 teeth from atomic-bomb survivors who received various radiation doses were analyzed in terms of possible solar light exposure by tooth position. Each tooth was divided into buccal and lingual parts for independent ESR measurement. We found that average buccal doses were larger than their corresponding lingual doses by 0.48 +/- 0.30 Gy (first ...

Dentigerous cyst is a benign odontogenic cyst associated with the crowns of permanent teeth. It is usually single in occurrence and located in the mandible of middle-aged persons. The teeth commonly affected are in order of frequency, the mandibular third molars, maxillary canines, maxillary third molars and, rarely central incisors. The present case report describes the surgical enucleation of...
