The aims of this study were to examine the enamel protective effect of a direct laminate veneer against acidic conditions, measure the amount of fluoride released from the veneer and which was taken up by the enamel, as well as evaluate the usefulness of the veneer for orthodontic treatment. First, a veneer was applied to rabbit incisors. Then, apart from using profile measurement microscope an...

Chronic smoking can lead to failure of Osseo integration due to decrease in local blood flow and failure of cell proliferation by by-products of smoking. This along with immediate failure of a malpositioned implant, devitalization of adjacent tooth necessitating a call for endodontic treatment or the fracture of the adjacent tooth due to malpositioned implant, fracture of the prosthesis due to ...

Dental implant prosthetics are extensively used as replacement for missing teeth in patients. However, interproximal contact loss between the and tooth has been reported by several studies. Because implants osseointegrated remain immobile within bone, wear of adjacent may impair tooth. Contact gauges commonly examination interdental separation natural dentition; however, effectiveness such fuze...

A possible cause for dental implant failure is the periapical implant lesion (PIL). In this case report we describe an apical periodontitis on a tooth adjacent to a dental implant that may have communicated with the apical region of the dental implant, and causing retrograde peri-implantitis. To our knowledge this is the first report demonstrating the concomitant successful treatment of the per...

Objective. Fusion is a dental anomaly that arises through the union of two adjacent teeth. The case report presents multidisciplinary management of a fused maxillary anterior tooth. Case Report. A 10-year-old boy was referred to the pediatric dental clinic with the chief complaint of a large upper anterior tooth. Intraoral and radiographic examinations indicated fusion between the permanent max...

odontogenic tumors are derived from epithelial, ectomesenchymal and/or mesenchymal elements that are or have been a part of the tooth-forming apparatus. of all the odontogenic tumors, calcifying epithelial odontogenic tumor accounts for 1% of the cases. approximately 200 cases have been reported to date. there is no sex predilection, with a 2:1 predilection for the mandible, mostly in the premo...

Transposition is a dental anomaly characterized by the exchange of position between two adjacent teeth, especially in relation to their roots, or development and eruption of a tooth in a position normally occupied by a nonadjacent tooth. Transposition of the maxillary canine and first premolar has a low prevalence in the population and it primarily affects maxillary canines and premolars. The a...

OBJECTIVE To assess the discrepancies in marginal integrity and contact points of Porcelain Fused to Metal (PFM) crowns and its association with caries in adjacent teeth. STUDY DESIGN Cross-sectional study. PLACE AND DURATION OF STUDY Dental Section of the Aga Khan University Hospital, Karachi, from January to August 2009. METHODOLOGY Ninety six (96) patients with PFM crowns on maxillary ...

a 48 year old patient was candidate for anterior mandibular reconstruction by 2 fixtures of branemark implant. residual infection lead to removal of one of the implants from the extracted tooth socket. afterwards, 2 fixtures of bonefit was inserted adjacent to previously placed branemark implants and final prosthesis were loaded in a joint cemented and screwed design.
