Expression of keratins 8, 18, and 19 in epithelia of atrophic oral lichen planus.

Keratins form intermediate filaments of the cytoskeleton in keratinocytes and have roles in cell structure, signaling, intracellular transport, and cell death. Oral lichen planus (OLP) is an oral inflammatory disease with derangements in basal keratinocytes and disruption of the basal membrane. Here, we focused on epithelial expression of keratins 8, 18, and 19 because these proteins are known to modulate cell death.

Pattern of recurrence of nonsyndromic keratocystic odontogenic tumors.

Objective: To describe and analyze recurrent pattern of KOTs according to time.

Study Design: This retrospective chart study evaluated histologically confirmed nonsyndromic keratocystic odontogenic tumors (KOT) treated at our institutions between 1975 and 2012.

Results: Mean age at time of diagnosis was 48 years, and male/female ratio was 1.

Dental auto-transplantation to anterior maxillary sites.

Aim: To investigate the indications for, and the outcome of auto-transplantation of teeth to the anterior maxillary region.

Material And Methods: From 1978 to 1994, 41 teeth in 31 subjects were transplanted to anterior maxillary sites at the Department of Oral Surgery, Stavanger University Hospital, Norway. All transplantations were performed by one oral surgeon (B.

Host response to titanium dental implant placement evaluated in a human oral model.

Background: Recent reports have questioned if metal sensitivity may arise from exposure to titanium. The objective of this study was to histologically evaluate non-perforated mucosa covering submerged maxillary titanium implants with regard to induced tissue reactions.

Methods: Thirteen patients, 21 to 69 years of age, without previous implants were included.
