We studied whether obturing canals and restoring endodontic occlusal access cavities on upper premolars could provide acceptable resistance and pattern to fracture. Eighteen upper premolars were divided equally into 3 groups. Group 1 consisted of intact controls; group 2 had access cavities and root canal preparations; group 3 as in group 2 but obturated with gutta-percha and AH26, and the acce...

hyperdontia or supernumerary teeth in both arches without any syndromic manifestation are extremely rare. supernumerary teeth are commonly associated with gardner’s syndrome, cleft lip and palate, cleidocranial dysplasia and trichorhinophalangeal syndrome. five cases of non-syndromic multiple premolars of maxillary and mandibular arches in indian patients are presented here. this case series re...

Objective. To determine the structural features of root canals mandibular premolars and molars, to assess quality endodontic treatment on basis cone-beam computed tomography (CBCT). Materials methods . The structure 50 teeth (premolars molars mandible) after performed was studied retrospectively CBCT in patients. number roots, as well their angle inclination, presence additional were taken into...

Aim Compare efficacy of Dual Rinse HEDP with sodium hypochlorite to in combination a finishing rinse 17% EDTA solution remove the smear layer. Materials and methods Sixteen human maxillary single-rooted, single canalled sound premolars were used. Specimens distributed into 2 groups labeled according irrigation protocol Each group consisted 8 specimens: Group 1 50% NaOCl followed by EDTA. The Ri...

INTRODUCTION Exploration and determination of the relationship between stature and length of tooth is essential in Paleontology, Forensic Odontology and Endodontology. This study aimed to determine any association between stature and posterior tooth length in a group of patients who required root canal treatment. METHODS Age, sex and standing height of adults were considered for posterior too...

The elimination of necrotic and inflamed pulp tissue, dentin debris, microorganisms is essential for the success endodontic treatment. However, root canal’s complexity has led to incomplete cleaning disinfection. This study aims compare efficacy penetrability three different irrigation activating techniques apical third canal. Sixty sound single-rooted human mandibular premolars are prepared wi...
