Impaction of mandibular second permanent molars is a rare occurrence, with prevalence rates reported to be between 0.65% and 2.0%. In the absence of systemic conditions, impactions are usually unilateral. There appears to be no consensus as to the optimal treatment for impacted mandibular second molars and treatment plans will be based upon the individual case. Treatment may involve orthodontic...

MATERIALS AND METHOD Fig: 1 Extracted Mandibular molars selected for the study

PURPOSE This study was performed to compare the accuracy of micro-computed tomography (CT) and cone-beam computed tomography (CBCT) in detecting accessory canals in primary molars. MATERIALS AND METHODS Forty-one extracted human primary first and second molars were embedded in wax blocks and scanned using micro-CT and CBCT. After the images were taken, the samples were processed using a clear...

MATERIALS AND METHOD: Methodology: 50 recently extracted molars were taken divided into two groups i.e. Group 1- Pro taper next -2 Wave One. distal root discarded mesiobuccal canals selected. Further selected scanned standa...

OBJECTIVE: To find out number of roots, root-canals and canal configuration in permanent mandibular third molars through tooth clearing technique. METHODS: In this cross-sectional study, 193 extracted human with completely formed apical foramen intact roots were collected from both genders treated at dental hospitals Peshawar, Pakistan 1st July to 31st December 2019. After collection teeth visu...

canal) in the extracted permanent maxillary first molars of a Sulaimani population. An ex vivo study on 180 extracted permanent maxillary first molars was conducted and the floor of the pulp was clearly exposed. The canal orifice was examined clinically by the aid of a chelating agent and magnifying lens. Patency of each canal was established by a no.10 k-type file. The results showed that 23.3...

In this study we used a biocomplex constructed from dental pulp stem/progenitor cells (DPCs) and a collagen sponge scaffold for oro-maxillo-facial (OMF) bone tissue repair in patients requiring extraction of their third molars. The experiments were carried out according to our Internal Ethical Committee Guidelines and written informed consent was obtained from the patients. The patients present...

A total of 139 extracted mandibular second molars were injected with India ink and demineralized. They were made clear and transparent with methyl salicylate, and the anatomy of their canals was studied. It was found that 86.3% of mandibular second molars had two roots, 9.3% had one root, and 4.3% had three roots. Ninety percent of the mesial roots of the mandibular second molars with two roots...

The objectives of this study were to measure the Furcation Entrance Dimensions of first and second permanent molars in Malaysian samples and to compare the Furcation Entrance Dimensions with the blade widths of periodontal Gracey’s curette used for root surface instrumentation. A total of 199 extracted permanent teeth were measured, which comprised of 51 mandibular first molars, 51 mandibular s...
