background. efficient canal preparation is the key to successful root canal treatment. this study aimed to assess the cleaning and shaping ability, preparation time and file deformation of rotary, reciprocating and manual instrumentation in canal preparation of primary molars. methods. the mesiobuccal canals of 64 extracted primary mandibular second molars were injected with india ink. the samp...

successful endodontic therapy depends on adequate mechanical and chemical debridement of the canal which requires knowledge of the canal morphology. conventional radiography has been used to evaluate the canal type; however, direct digital radiography has recently been practiced for this purpose due to the shortcomings of conventional radiography. the aim of the present study was to compare the...

introdouction: canal length measurement is essential for proper endodontic treatment. any error or miscalculation in working length determination, particularly in curved canals, can result in complications during or after root canal therapy. digital radiography has enabled accurate measurement of curved canal length. in this study, we evaluated the accuracy of calibration of a complementary met...

AIM The aim of this study was to compare the effects of preparation with conventional stainless steel Flexofiles and Gates Glidden burs versus nickel-titanium GT rotary files in the shaping of mesial root canals of extracted mandibular molars. METHODOLOGY A total of 54 canals from 27 mesial roots of mandibular molar teeth were prepared using one of two methods by novice dental students. One c...

AIM The aim of this study was to investigate the prevalence of additional canals in maxillary first molars in a selected population in Nigeria. METHODS AND MATERIALS One hundred extracted teeth were collected from the Pedodontic and Oral Surgery clinics of the University College Hospital in Ibadan, Nigeria. The teeth were identified and their root planed to remove adherent soft tissues. Each ...

background successful endodontic treatment is dependent on the knowledge of root canal anatomy. objectives this study aims to investigate the root canal anatomy of mandibular first molars in an iranian population. materials and methods one hundred human mandibular first molars were collected and stored in 5.25% naocl. radiographic images of the teeth were taken in mesial, distal, and buccal asp...

supernumerary paramolars are a rare anomaly of the maxillofacial complex. they are more common in the maxilla than the mandible. this article reports a rare case of bilateral maxillary paramolars, their complications and management.

Accurate diagnosis of the root canal morphology and anatomy is essential for thorough shaping and cleaning of the entire root canal system and consequent successful treatment. This report describes a case of maxillary second premolar with two roots and three root canals (two mesial and distal palatal canals). The case report underlines the importance of complete knowledge about root canal morph...
