Efficacy of Codeine When Added to Paracetamol (Acetaminophen) and Ibuprofen for Relief of Postoperative Pain After Surgical Removal of Impacted Third Molars: A Double-Blinded Randomized Control Trial.

Purpose: The use of opioids in combination with nonopioids is common practice for acute pain management after third molar surgery. One such combination is paracetamol, ibuprofen, and codeine. The authors assessed the efficacy of codeine when added to a regimen of paracetamol and ibuprofen for pain relief after third molar surgery.

The thickness of parietal bones in a new zealand sample of cadaveric skulls in relation to calvarial bone graft.

Objectives To evaluate the average thickness of the parietal bones in their different regions to identify the ideal site(s) for calvarial bone graft harvest. Methods and Materials Thickness of the parietal bones of 25 wet cranial vaults of New Zealand European origin was measured in 135 different locations using an electronic caliper. Analyses to identify the ideal harvest sites were conducted so that the sites fit the features of an ideal harvest site described in the literature as: (1) 6 mm of minimum thickness and (2) 2 cm away from the midline.

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.

Concordance between clinical and histopathologic diagnoses of oral mucosal lesions.

Purpose: To study the epidemiology of oral soft tissue lesions in New Zealand from 2002 to 2006 and to determine the concordance between the clinical diagnosis and the definitive histopathologic diagnosis achieved by general dental practitioners and by specialists.

Materials And Methods: The details from biopsy referrals and the corresponding histopathologic reports of oral soft tissue lesions were recorded into a statistical software package, and the concordance between the clinical diagnosis and histopathologic diagnosis was determined for all the lesions.

Results: Most biopsies were benign lesions, and both clinician groups achieved a high diagnostic concordance for these lesions.
