Abstract:The increased desire of patients to maintain their dentition has forced dental specialist to conserve the teeth in the mouth which are planned to be removed. In the light of this finding it is known that periodontally compromised teeth with severe bone loss at furcation area or endodontically compromised teeth may well be retained of their roots. This type of surgical therapy enables clinicians to better access the remaining tooth structure for periodontal and subsequent prosthetic therapy. In this case report palatal root resection of the right first maxillary molar with a simple procedure is presented along with a brief review of root resection as a treatment modality.

Modification of cotton fabric has been carried out through chemically induced graft copolymerization of binary mixture of acrylonitrile (AN) and 4-vinyl pyridine (4-VP) using ceric ammonium nitrate, (CAN) as initiator.

A mathematical model for the elastic behaviour of two phase composite body has been formulated. The distribution of stresses for various cases have been dis cussed together with their corresponding elastic energies. It has been shown that a great deal of knowledge can be obtained even without analysing the interaction mechanism of composite. The mixture is assumed to be homogeneous on a macroscopic scale but not necessarily isotropic. However, two phases themselves are assumed to be homogeneous and isotropic. Further, no condition is placed on the shape of the inclusions which may for example be fibrous or plate like.
