introduction: marginal seal integrity is important for a successful adhesive dental restoration. alterations caused by laser irradiation in the enamel and dentin surface can affect the marginal integrity of adhesive restorations. the aim of this study was to evaluate the microleakage of a composite resin restoration in primary teeth following laser irradiation of enamel and dentin. methods: for...

pharyngeal teratomas are rare. we present a mature solid teratoma (so called “hairypolyp”) involving naso- and oro- pharynx in a female infant who presented with a gradually enlarging mass at the roof of the mouth since birth. the pharyngeal mass was protruding into the mouth through a palatine defect present posteriorly which was removed completely. subsequently she developed malposed anterior...

If there are more than 32 teeth in the oral cavity, they are called supernumerous teeth. Distomolars are the fourth molar teeth, in the distal position to the wisdom teeth. Though, paramolars are the supernumerous teeth situated beside the molars. Correct diagnosis of supernumerous teeth is not always easy to conduct basing on pantomographic x-ray pictures. Obtained results indicate that unerup...

Analysis of adjacent tooth resistance is essential in wisdom teeth extraction to prevent adjacent tooth trauma, however it lacks adequate attention nowadays. This study aims at suggesting special extraction methods based on adjacent tooth resistance analysis for prevention of adjacent tooth damage. In this study, 136 complicated mandibular third molars extracted using piezosurgery were reviewed...
