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).

Non-Rigid Connector for Managing Pier Abutment in FPD: A Case Report.

A frequent clinical situation, either in the maxillary or mandibular arch, is of a missing first premolar and first molar, resulting in fixed partial denture design in which the canine and the second molar act as terminal abutments and second premolar act as a pier abutment. It has been postulated that the tendency of terminal abutments to intrude during function results in a teetering movements, where the pier abutment act as a fulcrum. These movements will eventually result in debonding of the less retentive terminal retainer.
