Impact of calcium hydroxide and 2-hydroxyisocaproic acid on the microhardness of root dentine: an in vitro study.

To evaluate and compare the effect of calcium hydroxide [Ca(OH)] and 2-hydroxyisocaproic acid (HICA) on the microhardness of root dentine. Fifty-one matured maxillary central incisors with straight root and type I canal configuration were decoronated to a standardized length of 16 mm. The root canals were cleaned and shaped using rotary instruments up to size F5.

Micronuclei frequencies and nuclear abnormalities in oral exfoliated cells of nuclear power plant workers.

Aim: Biomonitoring provides a useful tool to estimate the genetic risk from exposure to genotoxic agents. The aim of this study was to evaluate the frequencies of Micronuclei (MN) and other Nuclear abnormalities (NA) from exfoliated oral mucosal cells in Nuclear Power Station (NPS) workers.

Materials And Methods: Micronucleus frequencies in oral exfoliated cells were done from individuals not known to be exposed to either environmental or occupational carcinogens (Group I).

A sequential approach in treatment of endo-perio lesion a case report.

Endo-perio lesions primarily occur by way of the intimate anatomic and vascular connections between the pulp and the periodontium. Endodontic-periodontal combined lesion is a clinical dilemma because making a differential diagnosis and deciding a prognosis are difficult. An untreated primary endodontic lesion may become secondarily involved with periodontal breakdown, which clinically present unusual signs and symptoms.

Embryonal rhabdomyosarcoma occurring on mandibular gingiva in an adult.

An embryonal rhabdomyosarcoma (ERMS) is a primitive, malignant, soft tissue sarcoma that recapitulates the phenotypic and biological features of embryonic skeletal muscles. Occurrence of intraoral ERMS in adults is extremely rare. This unique case report highlights the clinical, radiographic, histopathological and immunohistochemical findings of an intraoral ERMS.

Evaluation of shear bond strength of silorane resin to conventional, resin-modified glass ionomers and nano-ionomer cements.

Aim: To evaluate the shear bond strength of silorane composite resin to conventional and resin-modified glass ionomer cements.

Materials And Methods: Shear bond strengths of Vitrebond (Group I), Ketac N100 (Group II) and Ketac Bond (Group III) glass ionomer cements to the composite Filtek P90 were evaluated. The bond strength was tested using a universal testing machine at a cross-head speed of 0.
