Complex and unusual root canal morphology is an often occurring phenomenon. Understanding the unusual root canal morphology contributes to success in endodontic treatment. One such variant root canal morphology is the 'S' shaped or bayonet shaped root canal. This case report discusses endodontic treatment of a maxillary second premolar with an 'S' shaped root canal.

The peripheral cementifying fibroma (PCF) is a reactive gingival overgrowth occurring frequently in the maxillary anterior region in teenagers and young adults. We report a case of peripheral cementifying fibroma occurring on the buccal gingiva in relation to the mandibular left canine & first premolar region in a 27 year old female patient.

Received: 6 Sept 2012 Accepted: 21 May 2013 Abstract Background and Aim: Tooth fracture is a common complication following MOD restorations.This study sought to assess the effect of different cusp coverage patterns on fracture resistance of maxillary premolar teeth in MOD composite restorations. Materials and Methods: In this invitro experimental study, 40human maxillary sound premolar teeth we...

INTRODUCTION Transposition is an anomaly of tooth position, the most frequent of which involves the canine and the first maxillary premolar. We describe the orthodontic treatment of a unilateral transposition of an upper canine and an upper right first premolar in the permanent dentition. CASE PRESENTATION A 12-year-old Caucasian boy presented with transposition of his upper right canine and ...

This report describes a novel concept of relocating orthodontic mini-implants during dental distalization to provide unrestricted distal movement of the full maxillary dentition. The patient was an 18-year old Korean woman with a full-step Class II Division 1 malocclusion and mandibular deficiency. Mini-implants were initially placed bilaterally between the maxillary second premolar and the fir...

Endodontic-periodontal lesion has been a diagnostic challenge. The present case report describes a case of localized primary periodontal lesion with secondary endodontic involvement in maxillary premolar. Its management was done by root canal therapy followed by periodontal regenerative procedure using Guided tissue regeneration technique.

BACKGROUND When a young patient accidentally loses two neighboring maxillary incisors, the choice of treatment plan is difficult. Although implant restorations are a popular option, they cannot be placed until skeletal growth is finished. Furthermore, the use of two neighboring implant crowns represents a considerable challenge from an esthetic point of view. This case report describes an innov...

A lateral periodontal cyst (LPC) is a rare finding. Patients diagnosed with LPC younger than 40 years of age are not that common. Mostly asymptomatic LPCs can be discovered on routine radiographs as an oval radiolucency between two mandibular premolar teeth roots and vary in shape size. Most cases treated enucleation, bone curettage, or combination both, greatly depending the surgeon’s preferen...

A technique for making a matrix and wedges for amalgam restoration of deep and concave gingival outlined proximal cavities is described. Two clinical situations involving concave surfaces of the maxillary first molar and premolar are illustrated. (Received for publication November 1984.)
