A Nevus of OTA with Intraoral Involvement: A Rare Case Report

Nevus of Ota, which originally was described by Ota and Tanino in 1939. It is characterized as congenital or acquired hamartoma of dermal melanocytes, presents clinically as a blue or gray patch on the face within the distribution of the ophthalmic and maxillary branches of the fifth cranial (trigeminal) nerve. Involvement of the palatal mucosa occurs rarely in nevus of Ota, when it occurs, it usually blends with the oral mucosa and is typically irregular, ill defined and often present as a mottled patch. Nevus of Ota is rare in the Indian subcontinent. So far very less cases of nevus of ota with intraoral involvement have been documented in the English literature. We report a rare case of intraoral nevus of Ota in a 20 year-old female patient

Drug-Induced Erythema Multiforme

Erythema multiforme (EM) is an acute inflammatory, mucocutaneous, psychosomatic, and vesiculobullous condition that varies from minor to major forms. The acral distribution of target lesions is a characteristic of this condition. The aetiology of erythema multiforme is multifactorial. 90% of the cases are triggered by a herpes infection, whereas 10% occur secondary to drug intake. The offending drugs include nonsteroidal anti-inflammatory drugs, antibiotics, and anticonvulsants. The present case series discusses four cases of drug-induced erythema multiforme and their management

Surgical management of deficient alveolar ridges by means of guided bone regeneration in oral implantology: A case series

Dimensional changes in the alveolar ridge after extraction often compromises on achieving optimal implant stability and placement of implants in the right prosthodontic positions. These situations demand augmentation of the residual ridge to achieve successful implant placement and long-term survival. A minimum amount of bone width and height is essential for the successful placement of implants. Unfavourable local conditions, due to atrophy, trauma and periodontal disease, may provide insufficient bone volume or an unfavourable interarch relationship, which does not allow correct and a prosthodontically guided positioning of dental implants. Guided bone regeneration, ridge splitting, block graft, or distraction osteogenesis have all been applied for this purpose and have shown some promising results. Nonetheless, autogenous block graft remains one of the main methods for reconstructing severely resorbed maxilla. These block grafts can be harvested from intraoral or extraoral sites. Significant amounts of autogenous bone can be procured from symphysis or ramus region of the mandible. The cortical grafts of this area provide predictable increase in bone volume with a short healing time and yield a highly dense osseous architecture for implant placement.This review discusses the use of autogenous block grafts and bovine bone allograft for predictable bone augmentation in atrophic ridges
