Cell cycle aberration in ameloblastoma and adenomatoid odontogenic tumor: As evidenced by the expression of p53 and survivin.

Context: p53 and survivin are involved in cell cycle progression and inhibition of apoptosis, respectively. Survivin is a unique protein which functions in progression of cell division and inhibits apoptosis leading to cell proliferation and cell survival. According to the literature, mutation of p53 leads to promotion of survivin function.

Revelation of Viral - Bacterial Interrelationship in Aggressive Periodontitis via Polymerase Chain Reaction: A Microbiological Study.

Background: Periodontal disease is one of the most common and complex disease affecting mankind. Being multifactorial in etiology it encompasses a variety of infectious entities with various unique microbial constellations and immune responses. A bacteriologic cause alone seems insufficient in explaining several clinical features of the periodontal disease.

Modified lip repositioning: A surgical approach to treat the gummy smile.

Gummy smile has been an esthetic concern for many patients. This clinical report describes a successful surgical coverage obtained by modified lip repositioning, thus surgically treating the gummy smile. The technique was performed to limit the retraction of elevator muscles (e.

Prediction of osteoporosis using dental radiographs and age in females.

Aims And Objectives: To evaluate the role of dental radiograph as a screening tool for diagnosis of osteoporosis in females.

Materials And Methods: In the present study, 50 women between the age group of 40-60 were recruited, and patients with systemic disorder and taking calcium supplements, and women who are not willing for investigation were excluded. Their detailed medical history was obtained and dental radiographs were made, bone mineral density was measured at left radial bone using ultrasound.

Occlusion calculator.

Start with end in mind' is a popular cliché in orthodontics. This aptly applies to the therapeutic occlusion the orthodontist strives to achieve. Predicting the post treatment occlusion is an essential component of treatment planning.

Lip repositioning.

Excessive gingival display is a frequent finding that can occur because of various intraoral or extraoral etiologies. This report describes the use of surgical lip repositioning technique for the management of a gummy smile associated with vertical maxillary excess and hypermobility of the upper lip. The procedure restricts the muscle pull of the elevator lip muscles by shortening the vestibule, thus reducing the gingival display when smiling.

Transmigration of mandibular canines.

The purpose of this paper is to present the first case of unusual reverse oblique (110 degrees to midsagittal plane) migration of mandibular right canine crossing the jaw midline and piercing the lower border of the mandible at the level of the opposite canine and also to report two more cases of transmigrated mandibular canine and one case of transmigrating mandibular canine. Mandibular canines are "cornerstone" of dental arch; their importance is manifested by their efficiency in masticatory function, stability of dental arch, and aid in maintaining natural facial expression. Early detection of this anomaly can help preserving these canines by orthodontic intervention or by surgical transplantation.

Intraosseous schwannoma of the mandible.

Schwannomas (neurilemmomas) are slow-growing, benign neoplasms derived from schwann cells, the sheath cells that cover myelinated nerve fibers. These tumors most commonly arise in the soft tissues of the head and neck, as well as on the flexor surfaces of the upper and lower extremities. Intraoral lesions are uncommon, however, and intraosseous schwannomas are even rarer.

Multiple glass pieces in paranasal sinuses.

Here, a case has been reported of a road traffic accident with multiple glass pieces arranged in an unusual pattern in the left maxillary sinus, ethmoid sinus, nasopharynx and medial side of the orbit, as seen in the radiographs. Combined surgical approach through the existing wound and endoscopic surgery was successfully used to remove nearly all the glass pieces.

Use of amnion as a graft material in vestibuloplasty: a clinical study.

The need to cover the exposed periostium has meant that a number of materials including mucosal and skin grafts are regarded as suitable for grafting in oral and maxillofacial surgery. To circumvent the disadvantages of other materials such as skin, biological membranes have been suggested as options, including fetal membrane. The objective of the present study was to evaluate the clinical efficacy of amnion as a graft material for vestibuloplasty, to increase the depth of the sulcus for complete rehabilitation with dentures in 10 patients with a follow up period of 3 months.
