A number of surgical procedures have been advocatedfor the reconstruction of defects in the oral cavityafter ablative surgery. This includes primaryclosures, skin grafts, local regional and distantflaps. The choice of a flap for reconstruction isgoverned by the type and size of defects and theadvantages and disadvantages of the variousreconstructive options.A large number of local methods have beensuccessfully employed for intraoral reconstructionsuch as oral mucosal flaps, my mucosal island flaps, tongue flaps, local muscular flaps such as temporalisor sternoceiodomastoid transfer and buccal fat pad. The use of a pedicled BFP graft is a logical, convenient, and reliable method for reconstruction oforal defects up to 4 cm in diameter on theipsilateral side of the soft palate and posterioralveolar ridge of the maxilla. It can also be used inconjunction with other local flaps and with regionalmyofascial flaps. Since both donor and recipientsites are in the oral cavity there is no visible scarin the donor are

The persisting bacterial presence, together with a lack of thoroughly hermetic seal between the prepared tooth walls and the final finished fixed prosthesis walls allow bacterial leakage and thus may be involved in the development of recurrent caries.several species of bacteria may be isolated from plaque associated with carious lesions and pulpal inflammation. Streptococcus mutants is one of the bacteria most frequently implicated in dental caries.Antibacterial activity, during and after setting, assumes clinical relevance because this property may help in the elimination or reduction of bacteria that have remained viable in the cavity wallsor bacteria that may gain access to the cavity through micro leakage channels.
