This study evaluated the effect of sandblasting foil mesh molar tube bases on the shear bond strength obtained when bonding to first molar teeth. Fifty-two recently extracted first molar teeth were etched with 35 per cent phosphoric acid gel for 30 seconds. Twenty-six sandblasted 'A' Company molar tube attachments and 26 non-sandblasted attachments were then bonded to the teeth using Phase II o...

Retention of primary teeth beyond the expected time exfoliation is uncommon; this condition known as persistence. A retained tooth, with crown in good condition, roots, and supporting alveolar bone can serve adults for many years. Aims- To determine prevalence investigate consequences their Materials Methods- ORTHOPANTAMOGRAM (OPG) data obtained from pediatric preventive dentistry 500 patients,...

PURPOSE The purpose of this project was to establish median eruption ages of primary teeth and evaluate eruption differences between contralateral teeth by gender, ethnicity, and household income. Data was derived from a caries study of preschool children. METHODS A total of 4,277 white (non-Hispanic) and Hispanic preschool children from Arizona were visually examined for caries and tooth eru...

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...

UNLABELLED Direct placement resin composite is revolutionizing the restoration of posterior teeth. Compared to amalgam, its use not only improves aesthetics but, more importantly, promotes a minimally invasive approach to cavity preparation. Despite the benefits, the use of composite to restore load-bearing surfaces of molar and premolar teeth is not yet universally applied. This may be due to ...

Relatively few long-term studies have been performed to evaluate the clinical success of one-appointment pulpectomies in primary molar teeth. The purpose of this retrospective study was to evaluate the radiographic appearance of nonvital primary molars before and after treatment with a one-appointment formocresol pulpectomy technique. The mean length of time since pulpectomy treatment for the 6...

Traumatic injury to the primary dentition is a common occurrence in young preschoolers. The maxillary incisors and, more specifically, the central incisors, are the most commonly injured teeth. The purpose of this article is to present the immediate and long-term treatment and management of a severe case of multiple avulsions involving all maxillary incisors and canines and the right first prim...
