AIM To assess the prevalence and to investigate the pathogenetic mechanisms of dental and periodontal lesions in children with X-linked hypophosphatemic rickets (XLH) examined at diagnosis or during treatment. METHODS Nine children with XLH (age 7.2 +/- 3.3 years) were enrolled in the study (at diagnosis, n = 2; during treatment with oral inorganic phosphate salts combined with 1,25-dihydroxy...

A case of bilateral fusion is presented, the definitions of fusion and gemination are reviewed, as well as the diagnostic criteria. The clinical implications of fused teeth include the probability of loss of arch length, caries susceptibility of the fissure, and missing corresponding permanent incisors. Introduction In 1963 Tannenbaum and Ailing, defined gemination as the formation of the equiv...

PURPOSE The aim of this study was to compare all ceramic inlay/onlay survival rates in vital and nonvital teeth having the same cavity design. Filling the pulp chamber with ceramic materials or not was also discussed. MATERIALS AND METHODS Ceramic class II inlays/onlays were made on 11 premolars and 30 molars: 14 vital, 27 endodontically treated. The same tooth preparation design was performe...

OBJECTIVES The purpose of this study was to examine the location and accessibility of the second mesibuccal canal in maxillary first molar of a Turkish sub-population. METHODS Presence and accessibility of the MB2 canal in 110 extracted maxillary first molars was examined with unaided vision, dental loups and the DOM. To characterize the geometrical location of MB2 canals, photographs of pulp...

Wood extractives, commonly referred to as pitch, cause major problems in the manufacturing of pulp and paper. Treatment of nonsterile southern yellow pine chips for 14 days with Pseudomonas fluorescens, Pseudomonas sp., Xanthomonas campestris, and Serratia marcescens reduced wood extractives by as much as 40%. Control treatments receiving only water lost 11% of extractives due to the growth of ...

The antimicrobial activity of visible light cure (VLC) calcium hydroxide pulp capping products was compared to self-cure products by an in vitro microbial assay. Individual microbial samples were collected from six deep carious lesions, sonicated, and plated onto duplicate T-soy blood agar. Uniform discs of each capping compound were pressed slightly below the surface of the agar and allowed to...

INTRODUCTION Dentin dysplasia is a rare hereditary disturbance of dentin formation characterized by defective dentin development with clinically normal appearing crowns, severe hypermobility of teeth and spontaneous dental abscesses or cysts. Radiographic analysis shows obliteration of all pulp chambers, short, blunted and malformed or absent roots and peri-apical radiolucencies of non carious ...

This report describes the extraction of a geminated maxillary right permanent central incisor in an 8-year-old white female followed by the autogenous transplantation of a maxillary left supernumerary incisor. A 2-year clinical and radiographic followup revealed no pathologic findings and confirmed continued root development and pulp vitality in the transplanted tooth. This report documents he ...

Capík I . , V. Ledeck ̆, A. ·evãík: Effects of Flumetazone on Exposed Dental Pulp of Dogs. Acta Vet. Brno 2003, 72: 279-283. Dental pulp metabolism plays very important role throughout the tooth life. Its role is essential particularly in the first two-three years. This is the time of the highest dentin deposition which provides sufficient firmness to withstand common everyday trauma. This study...

PURPOSE The objective of this project was to develop an in vitro model system for investigations of dentinal caries. METHODS Five extracted primary molar teeth with circular cavity preparations to the depth of the dentinoenamel junction were mounted individually in cold-cure acrylic bases constructed to fit a positioning jig in a Schick-Technologies digital radiographic imaging apparatus. The...
