Granular cell ameloblastoma is a rare variant, accounting for 1-5% (3.5%) of ameloblastomas. It has clinical behavior similar to other subtypes, and show high tendency to recur on conservative surgical approaches. It can also show metastasis, hence the treatment plan should include regular follow up of the patients, after radical surgery. Here we are presenting a case report of granular cell ameloblastoma occurring in a 45 years old male patient clinically, the lesion was occurring in the left posterior mandible creating soap bubble appearance on radiography. Histopathologically, granular cell changes were prominent. The granular appearance is due to lysosomal aggregation and their presence indicates degenerative change or related to aging phenomenon rather than aggressiveness. The lesion was treated by surgical resection and a period of 3 years follow up showed no recurrence.

All of us as clinicians at one time or another have to attend to dental emergencies involving severly fractured or even lost or avulsed anterior teeth. Treating such cases is often difficult and there is always a time factor involved. Loss of anterior teeth can affect a patient psychologically and socially. This can be minimised by an immediate replacement or replantation of the lost or avulsed teeth. Definitive treatment planning and consultation with specialists is seldom possible at the time of emergency treatment. Replantation of the avulsed tooth can restore esthetic appearance and occlusal function shortly after the injury. This article describes the management of a young female with an avulsed maxillary permanent incisor that had been air-dried for about 72 hours. The replanted incisor retained its esthetic appearance and functionality 8 months after replantation, yet the long-term prognosis remains questionable.

Hemisection is a corrective periradicular surgery, carried usually in mandibular molars to preserve the maximum amount of supporting structures of the natural dentition in a state of health and function.

Hemisection is done in mandibular molars wherein one of the two roots is devoid of bone and periodontal support. The main intention of hemisection is to retain a part of tooth root while removing the deceased part, which has a poor prognosis.

In this article hemisection for a left mandibular molar with Grade I mobility and no migration of the affected tooth No.36, with exudation from the pocket is described and discussed as a treatment approach for a lesion of primary periodontal origin with secondary endodontic involvement, similar to observations made by Hamp et a1⁹.

The indications advantages and limitations of hemisection as well as recommended literature on the subject are discussed.

Sclerosis of dentinal tubules may be a response to pathological or physiological insult in the crown & root that starts in the root and gradually extend to the crown of the tooth in case of physiological sclerotic dentin. The exact mechanism of the formation of sclerotic dentin is not known, however various authors have proposed different possible mechanisms, which are not universally accepted but, it is generally agreed that sclerotic areas of root dentin increases in size with age.

Turnaround time is an important consideration in surgical pathology. Attempts to shorten the time necessary for making a histopathological slide from the surgical tissue has been tried in various ways since many decades without compromising the quality of it. One amongst such attempt is the introduction of microwave to the field of his totechnology.

Microwaves, a form of electromagnetic wave induced heat when applied in histotechnology, reproducibly yields histolologic material of similar or superior quality to that provided by conventional processing methods making it more popular in the recent years. A laboratory microwave offers features like maximum output of 2000-3000 watts, an in built source of adjustable temperature probe, facility for ventilation of hazardous fumes, but is expensive. Considering the usefulness of microwave in histotechnology by reducing the time required for the diagnosis, replacing the conventional equipments of laboratories to microwave guided ones is a remarkable and an acceptable change.

Oral mucositis is a frequent adverse reaction of radiation therapy of head and neck malignancies. The incidence and severity of these sequelae of radiation have increased with the use of altered fractionated schedules and concurrent chemotherapy. Mucositis may confine the patient's tolerance of antineoplastic therapy, and the nutritional status is endangered. Thus, the cancer treatment may be dramatically affected along with the patient's quality of life. In order to prevent and treat this condition many treatment options are available, but the complete, effective prevention and therapy cannot be achieved. Research leading to a better understanding of the mechanisms of mucosal injury will ideally result in more specific, more targeted, and effective strategies for prevention of mucositis rather than current management algorithms that rely primarily on costly symptom management.
