The radiographic anatomy of the superior borders of pulpal chambers of primary molars was studied to clarify interpretation of superimposing cuspal images. First and second maxillary and mandibular molars were sectioned transaxially in the cervical region. The pulpal tissue was replaced by radiopaque resin before embedding the crowns in clear plastic blocks and obtaining buccolingual radiograph...

introduction: adequate seal of iatrogenically perforated area within the root canal system can improve the long term treatment prognosis. this in vitro study evaluated the sealing ability of mineral trioxide aggregate (mta), calcium-enriched mixture (cem) cement and biodentine in repair of furcation perforation in primary molars. methods and materials: a total of 61 freshly extracted primary ma...

OBJECTIVE To describe and compare patterns of tooth loss in 2 groups of 21- to 25-year-old Hong Kong Chinese patients examined 15 years apart. MATERIALS AND METHODS The panoramic radiographs of consecutive young adult patients who attended the primary care department of the Dental School of the University of Hong Kong in 1983 and 1998 were reviewed. RESULTS The proportions of patients with ...

Caries is a tooth surface disease characterized by demineralization caused acids produced bacteria during the metabolism of sugar food. Molars are primary teeth that most prone to caries. One causes caries poor dental and oral hygiene. Preschoolers have lower awareness adherence hygiene, increasing risk The objective this study was examine description molars as well effect health education on h...

Glass ionomer cements are tooth-coloured materials that bond chemically to dental hard tissues and release fluoride for a relatively long period. They have therefore been suggested as the materials of choice for the restoration of carious primary teeth. However, the clinical performance of conventional and metal-reinforced glass ionomer restorations in primary molars is disappointing. And altho...

The behavior of pulp tissue under two concentrations of formocresol was evaluated radiographically and histologically in pu/potomized primary and young permanent monkey teeth. A faster resorption rate of the roots of the treated primary teeth was observed with both concentrations. Evidence of vital tissue as expressed by continued root development was observed in the permanent teeth of both tre...

PURPOSE The purpose of this study was to evaluate the color of primary teeth. METHODS A Vita Easyshade intraoral spectrophotometer was used to determine the color of primary teeth: (1) maxillary central incisors, canines, and first molars; and (2) mandibular central incisors, canines, and first molars. A total of 604 teeth were measured. Color difference was compared to DeltaE*=2.7 (mean=50:5...

Two clinical cases in which Portland cement (PC) was applied as a medicament after pulpotomy of mandibular primary molars in children are presented. Pulpotomy using PC was carried out in two mandibular first molars and one mandibular second molar, which were further followed-up. At the 3, 6 and 12-month follow-up appointments, clinical and radiographic examinations of the pulpotomized teeth and...
