Aim: Various odontogenic cysts may occur in the jawbones during childhood, including radicular cysts, dentigerous and keratocysts. Treatment for such ranges from conservative approaches to radical surgical procedures. The present study evaluates effect of only decompression method treating various children. 
 Materials Methods: A total 16 pediatric patients (four girls, 12 boys; mean age 9...
Background and Aims: Debonding at the cement-dentine interface is the main reason of failure in restoration of endodentically treated teeth with fiber posts. The aim of this study was to compare the effect of Starfill 2B danville and Panavia F2 kuraray cements on the retention of fiber posts to root canal dentin. Materials and Methods: Twenty extracted mandibular premolar teeth which had...
Background and Objective: Despite developing use of fiber reinforced composite posts (FRC), some studies disputed the effect of this kind of posts on fracture resistance of teeth. The aim of this study was to evaluate the effect of FRC posts on fracture resistance of teeth restored with crown. Materials and Methods: After root canal therapy and cutting the crown, forty human maxillary pr...
Background and Aim: White spot lesions (WSLs) are common occurrence following orthodontic treatment, this study sought to compare the remineralizing potential of fluoride, MI Paste Plus (CPP-ACP-F) and Remin Pro for treatment of WSLs. Materials and Methods: This in vitro study was conducted on 56 sound human premolars that extracted for orthodontic purposes. Teeth were cleaned and their root...
Background: Teeth have an important role in a person, the most common cause of tooth loss is caries and periodontal disease. Tooth can be overcome by making dentures, removable denture components consist dental elements, clasps, bases. The base part that rests on soft tissues oral cavity where elements are attached. One mechanical properties for bases flexural strength. Acrylic resin material h...
BACKGROUND oligodontia is a condition with developmental absence of six or more permanent teeth excluding the third molars. It is a rare finding which has not been frequently documented in Nigerian children. OBJECTIVE to report a case of non syndromic oligodontia. METHODS The details of the clinical presentation, course and outcome of a 9-year-old child with oligodontia were reviewed. The c...
The purpose of the study was to evaluate the shear bond strength of stainless steel orthodontic brackets directly bonded to extracted human premolar teeth. Fifty teeth were randomly divided into five groups: (1) System One (chemically cured composite resin), (2) Light Bond (light-cured composite resin), (3) Vivaglass Cem (self-curing glass ionomer cement), (4) Fuji Ortho LC (light-cured glass i...
INTRODUCTION The resistance to fracture of endodontically treated teeth restored with esthetic post systems has not been extensively researched. This in vitro study compared the fracture patterns of endodontically treated teeth with esthetic post systems with different analysis methods. MATERIALS AND METHODS A total of 26 recently extracted human maxillary central incisors were decoronated an...
The methods used for disaster victim identification is comparative postmortem profiling of dental and fingerprint data. Twelve dental concordant features are normally required for dental identification. The radiographic image of dental amalgam restorations has been shown to be highly significant for identification purposes. The aim of this study was to investigate the radiological morphology of...
A recent study showed that orange-red fluorescence in carious dentin could be used to detect residual caries (Lennon & others, 2002). This study compared the ability of a new fluorescence-aided caries excavation technique (FACE) with the conventional method. Forty extracted teeth with occlusal dentin caries were selected. The teeth were bisected longitudinally through the center of the lesion. ...
