The rectilinear Steiner tree problem (RSTP) is a classical problem having numerous real-world applications, including VLSI routing. Since the RSTP is NP-hard, developing polynomial heuristics which can produce near optimal solutions has been the primary approach to solve the RSTP. Many of these algorithms (e.g., 1-Steiner) use Hanan points. However,(More)
Central giant cell granuloma (CGCG) is a benign, non-odontogenic bone lesion of jaw. The condition is relatively infrequent and affects mainly children and young adults with a certain predominance among females and exhibits variable aggressiveness. Giant cell lesion associated with hyperparathyroidism is known as Brown tumor. Brown tumor is one of the bony(More)
OBJECTIVE The study was done to compare the clinical efficacy of vacuum formed splints and arch bar in treating minimally displaced mandibular fractures. METHOD Forty patients were included in two groups. Group 1 was treated with custom made splints and group 2 with conventional arch bar. Patients were recalled on 3rd, 7th, 14th day and on the day of(More)
Research into regenerative dentistry has contributed momentum to the field of molecular biology. Periapical surgery aims at removing periapical pathology to achieve complete wound healing and regeneration of bone and periodontal tissue. Regenerative endodontic procedures are widely being added to the current armamentarium of pulp therapy procedures. The(More)
Use of vasoconstrictors in local anaesthesia is well known. The study was done on 30 patients who underwent removal of bilateral impacted third molars. The aim of the study was to compare the efficacy of lignocaine with clonidine and lignocaine with adrenaline in respect to onset, duration of anaesthesia, and postoperative analgesia along with hemodynamic(More)
AIMS To understand and evaluate the significance of various aetiological factors in determining the incidence and dictating the patterns of mandibular fractures in Rohilkhand region. METHODS The patient records and radiographs for 144 patients treated for mandibular fractures were reviewed between the time periods from January 2012 to December 2013. Data(More)
Ablative surgery for head and neck tumors is associated with significant disfigurement and loss of function. The main aim of the surgeon is to provide functional ability and esthetics of the patient. Type and extent of tissue loss from surgery relates to loss of soft tissue and bone. Reconstructions of jaw and mouth defects represent a challenge to the(More)
ABSTRACT TMJ ankylosis is one of the most disruptive anomaly that affects the masticatory system. The inability to move the mandible has significant functional ramification, such as the inability to eat a normal diet. Additionally, speech is affected, making it difficult for some individuals to communicate and express themselves to others. As there are(More)
