OBJECTIVE To evaluate and compare the cleaning ability of the more biocompatible 1% sodium hypochlorite (NaOCl) with passive ultrasonic irrigation (PUI) to that of 2.5% NaOCl with syringe method irrigation. MATERIAL AND METHODOLOGY Thirty-six extracted permanent single-rooted mandibular premolar teeth were decoronated at the cemento-enamel junction and divided randomly into four groups (nine ...

INTRODUCTION A coronal barrier in root-filled teeth is one of the most effective methods for prevention of coronal microleakage. The aim of this study was to compare coronal microleakage of three materials [light-cured glass-ionomer (GI), mineral trioxide aggregate (MTA), and composite resin] as coronal barriers. MATERIALS AND METHODS A total of 188 intact maxillary incisors were used. After ...

The aim of the present cross-sectional investigation was to evaluate percentage of bone loss in patients who had been one year under periodontal maintenance at the Department of Periodontology, Faculty of Dentistry, University of São Paulo by radiographic analysis. Complete sets of periapical radiographs provided data regarding percentage of alveolar bone loss, which was correlated with arches,...

OBJECTIVE The aim was to examine dental and periodontal status of adult Croatian 18th century population and compare the results with available literature data. MATERIALS AND METHODS 104 specimens from the crypt of Požega cathedral were grouped into three female and three male groups according to age. Caries was determined by visual inspection and dental probe. Ante and post mortem teeth loss...

Objectives: Microleakage is a major cause of failure of dental restorations and results in development of secondary caries, tooth hypersensitivity and pulp pathosis. This study aimed to compare the microleakage of class II cavities filled with two types of composite resins and a compomer and subjected to thermocycling. Methods: In this in vitro experimental study, class II cavities with a gi...

OBJECTIVES To establish a normal range for the radiographic distance between cementoenamel junction and alveolar bone crest and the factors affecting distances for the early assessment of periodontal disease in Dravidian pediatric population. METHODS Fifty children aged 6 to 8 years were selected based on inclusion and exclusion criteria. Clinical and radiographic examination was performed. A...

The number and the mean percentage tubular cross-sectional area of dentinal tubules per square millimetre were calculated in specimens of coronal dentine of 13 intact human third molar teeth from patients 18 to 28 years of age. The dentine was fractured at various known distances from the dentino-enamel junction. Near the dentino-enamel junction the number of tubules per square millimetre was 2...

objectives: microleakage is a major cause of failure of dental restorations and results in development of secondary caries, tooth hypersensitivity and pulp pathosis. this study aimed to compare the microleakage of class ii cavities filled with two types of composite resins and a compomer and subjected to thermocycling. methods: in this in vitro experimental study, class ii cavities with a gingi...

This study explores the internal morphology of early hominid teeth using high-resolution computed tomography. Data on Carabelli feature size, enamel thickness, and the topography of the enamel-dentine junction are considered together in order to examine the relationship among these variables in the maxillary molars of gracile and robust australopithecines from South Africa. In particular, one a...

The aim of this in vitro study was to to evaluate the impact of finishing procedures on the enamel adjacent to composite restorations and to assess if the resistance of the enamel-resin junction to leakage is affected by the use of these instruments. The surfaces of enamel at the joint with composite were observed by scanning electron microscopy, then the microleakages at the enamel margin was ...
