Cemento-Ossifying fibromas are rare fibro-osseous lesions that affect the jaw bones and are included in the group of mesodermal odontogenic tumours. Clinically, it is a large asymptomatic tumor of aggressive appearance. Four separate categories have been identified: Periapical cemental dysplasia, benign cementoblastoma, cementifying fibroma and a rare gigantiform variety. It has been suggested that the origin of these tumour is odontogenic or from periodontal ligament. This lesions commonly seen in women in 3rd and 4th decade of life. Usually in the jaw region the lesions are found mostly in the tooth bearing area. In this article, we present two cases of unusual presentation of Central Ossifying Fibroma involving lower border of mandible and its management.

An implant-supported overdenture may be practically advantageous over conventional complete denture and removable partial denture. They reduce bone resorption and has greater prosthesis stability, improved maintenance and better esthetics. Implant supported overdenture may reduce the amount of soft-tissue coverage and extension of the prosthesis. Hygiene condition and home maintenance procedures are improved with the overdenture compared with fixed prosthesis. Implant supported overdenture limits lateral movements and consequently minimize soft-tissue trauma. Greater stability of implant-supported overdenture drives from mechanical attachment of the implant support system retaining the restoration. In severe resorption cases, this is a better alternative than the fixed restoration.

Sleep-disordered breathing (SDB) includes mouth breathing, snoring, upper airway resistance syndrome (UARS), and obstructive sleep apnoea (OSA). Obstructive sleep apnoea is defined as 5 or more episodes of complete (apnoea) or partial (hypopnea) upper airway obstruction per hour of sleep. In this case report we are describing one such case of sleep apnoea where patient is treated using devices. Satisfactory results were acquired post appliance insertion in the patient thereby indicating that in moderate cases appliances can be used to manage sleep apnoea.

Periodontal disease has been recently linked to a variety of systemic conditions such as diabetes, cardiovascular disease, preterm delivery, and oral cancer. Oral Squamous Cell Carcinoma is a lethal disease whose incidence is increasing. The most common bacteria associated with periodontal disease, Porphyromonas gingivalis (P. gingivalis) has not yet been significantly studied in the malignant gingival tissues. The objective of this study was to investigate the presence of P. gingivalis in specimens taken from the deeper tissue biopsy in squamous cell carcinoma patients. We have performed Real Time Polymerase Chain Reaction(PCR) technique to investigate the presence of P. gingivalis in deeper tissue biopsy samples of gingival squamous cell carcinoma. P. gingivalis is abundantly present in malignant oral epithelium suggesting a potential association of the bacteria with gingival squamous cell carcinoma. These observations may help to explain, in part, the predominant role that P. gingivalis plays as an infectious agentin oral malignant patients.
