Although clinician's skills and experience play a major role in designing and fabrication of the optimum prosthodontic restorations, the selection of denture resins is equally important, especially when the patient has been using the prostheses since long. Eighteen cases who were not satisfied with their conventional acrylic dentures were selected. They were provided flexible dentures along with a questionnaire to precisely evaluate the advantages of new material. Prosthodontic planning & observations regarding this material are discussed on various parameters.

Cases of severe attrition are a common finding in daily clinical practice. Attrition leads to loss of vertical dimension, chewing inefficiency and poor esthetics. These cases require complete oral rehabilitation which can be successfully achieved by a systematic approach integrating various concepts of prosthodontics. The primary aim of such complex treatment modalities is to regain the lost function, esthetics, comfort and confidence for the patient. The following case report describes the complete oral rehabilitation of a patient diagnosed of mutilated dentition and reduced vertical dimensions due to severe attrition. A detailed treatment plan was chalked out which included institution of proper oral hygiene measures, extraction of teeth with poor prognosis, restoration of carious teeth, endodontic treatment for carious teeth with periapical involvement. This was followed by foundation restorations of teeth that were crucial for the final prostheses. Patient was given transitional restorations for about 6 weeks with the aim of regaining the lost vertical dimensions. Final rehabilitation was done by fixed dental prostheses.

Many people would prefer to keep their natural teeth and advances in dentistry have lead to treatment of teeth that once would have been removed. In order to carry out this present day mandate, hemisection is the procedure of cutting a tooth that has two roots in half. This will create a front half and a back half. This procedure can be done by a periodontist, an experienced dentist, an endodontist, or an oral surgeon. This article describes a simple procedure for hemisection in mandibular molar and its subsequent restoration.

Success of endodontic therapy depends on the proper identification of all the canals, thorough chemo-mechanical preparation followed by three dimensional obturation with fluid tight seal. Failure of any of these steps may occur due to unusual tooth morphology. Proper knowledge of root canal anatomy is a basic prerequisite for the endodontic treatment successful. Mandibular molars may have an additional root located lingually (radix entomolaris) or buccally (radix paramolaris). Awareness and understanding of the presence of unusual external and internal root canal morphology contributes to the successful outcome of the root canal treatment.Bangladesh Journal of Dental Research and Education Vol.5(2) 2015: 66-69
