Oral epithelial dysplasia: Causes, quantification, prognosis, and management challenges.

Oral epithelial dysplasia is a spectrum of architectural and cytological epithelial changes caused by accumulation of genetic changes, and is associated with an increased risk of progression to squamous cell carcinoma. It is a microscopic diagnosis of immense clinical importance. The initial reports of oral potentially malignant disorders with oral epithelial dysplasia transforming to oral cancer helped in understanding the nature of oral malignancies.

Oral mycosis fungoides: report with immune profile.

Mycosis fungoides (MF) is a cutaneous T-cell lymphoma that uncommonly involves the oral mucosa. Oral MF is an indication of systemic progression and is often associated with an unfavorable outcome. Any oral mucosal site may be affected.

Soft and Hard Tissue Response to Zirconia versus Titanium One-Piece Implants Placed in Alveolar and Palatal Sites: A Randomized Control Trial.

Background: Titanium (Ti) implants have been used in the last four decades to replace missing teeth. Alternatives to Ti such as zirconia (Zr) may offer aesthetic advantages and be more acceptable to patients and clinicians concerned about Ti allergy but must show equivalent biological acceptability to Ti.

Purpose: The research aimed to investigate soft and hard tissue response to Ti and Zr implants in edentulous patients.

Facial attractiveness of skeletal Class II patients before and after mandibular advancement surgery as perceived by people with different backgrounds.

The purpose of this study was to determine the perceived level of improvement in facial attractiveness as assessed by people with different backgrounds in skeletal Class II patients treated by mandibular advancement with bilateral sagittal split osteotomy (BSSO). The frontal and lateral pre- and post-operative photographs of 10 Caucasian patients were selected. Changes in frontal and profile attractiveness were assessed by 10 orthodontists, 10 art students, and 10 laypersons.

A nine-year review of orthognathic surgery at the University of Otago.

Objective: To describe the demographic characteristics of patients undergoing orthognathic surgery at the University of Otago over a nine-year period.

Methods: The case notes of patients who underwent orthognathic surgery procedures at the University of Otago from 2001 to 2009 were reviewed retrospectively. This was augmented with a brief literature review of surgical considerations and complications in orthognathic surgery among older patients.

A case series of odontogenic keratocysts from a New Zealand population over a 20-year period.

Purpose: To report on the clinicopathological aspects of odontogenic keratocysts (OKC)/keratocystic odontogenic tumours (KCOT) presenting in a New Zealand population.

Methods: Information on defined areas--including age at presentation, gender, anatomical sub-location, presenting features, histological subtype and the recurrence pattern--were extracted from the histopathological data available in the Oral Pathology database of the University of Otago School of Dentistry.

Results: Two hundred and twenty three cases of OKC/ KCOT were identified over the period ranging from 1987 to 2008.

Influence of a pedicle flap design on acute postoperative sequelae after lower third molar removal.

Pain, swelling, trismus, and alveolar osteitis often occur after removal of impacted third molar teeth. To minimize these complications a number of mucoperiosteal flap designs have been advocated, but, to date, a pedicle flap design has not been evaluated. In a randomized prospective split mouth study, 52 participants had bilateral symmetrically impacted mandibular third molars removed over two sessions.

Titanium allergy: could it affect dental implant integration?

Purpose: Degradation products of metallic biomaterials including titanium may result in metal hypersensitivity reaction. Hypersensitivity to biomaterials is often described in terms of vague pain, skin rashes, fatigue and malaise and in some cases implant loss. Recently, titanium hypersensitivity has been suggested as one of the factors responsible for implant failure.

Simultaneous modelling of the Michaelis-Menten kinetics of paracetamol sulphation and glucuronidation.

1. The aim of the present study was to perform an in vivo estimation of the Michaelis-Menten constants of the major metabolic pathways of paracetamol (APAP). 2.

Immediately restored, single-tapered implants in the anterior maxilla: prosthodontic and aesthetic outcomes after 1 year.

Background: Conventional implant protocols advocate a two-stage technique with a load-free, submerged healing period. Recent studies suggest that immediate restoration of single implants may be a viable treatment option.

Purpose: The purpose of this study was to evaluate prosthodontic and aesthetic peri-implant mucosal outcomes of immediately restored, Southern single-tapered implants in the anterior maxilla after 1 year.
