OBJECTIVES: The aim of this study was to investigate for the first time the histological response of periodontium to mineral trioxide aggregate (MTA) and Biodentine in human experimental models. MATERIALS AND METHODS: Six patients scheduled for implant full-arch rehabilitation via the all-on-4 technique were randomly assigned to one of the two test groups: either to MTA or Biodentine treatment. For each patient, 2 teeth scheduled for strategic extraction were randomly assigned either to the test or to the control treatment...

BACKGROUND: This study aimed to examine if specific micronutrients were associated with periodontal disease using data from the United States National Health and Nutrition Examination Survey (NHANES) from 2011-2014. METHODS: Participants who were ≥ 30 years of age and received complete periodontal examinations were included. Regression analyses were performed to determine associations of variables of interest with periodontal disease. RESULTS: Data of 6,415 NHANES participants were included in the analysis...

BACKGROUND: Tooth discolouration could occur due to bacterial contamination in traumatised teeth. Hydrogen peroxide is the commonly used bleaching agent. However, due to concerns over safety, alternative-bleaching regimes such as sodium perborate (S) and thiourea-hydrogen peroxide (T) have been investigated. METHODOLOGY: Apices resected and pulp extirpated 99 premolars were divided into two groups. Group 1 and 2 was injected with blood and blood/bacteria, stored anaerobically for 35 days...

BACKGROUND: Osteonecrosis of the jaw (ONJ) is a serious complication of both radiation and antiresorptive therapies. This study aimed to determine how many patients have been treated for medication-related osteonecrosis of the jaws (MRONJ) and osteoradionecrosis (ORN), and whether the number of diagnoses has decreased over time with improved awareness and preventative measures. METHODS: Medical records at the Royal Brisbane & Women's Hospital, Gold Coast University Hospital, and Robina Hospital were reviewed to identify patients diagnosed with MRONJ and ORN between January 2003 - May 2017...

AIM: This study compares diamond burs and curettes by clinical, microbiological, biochemical, scanning electron microscopic parameters and treatment time data in the non-surgical periodontal treatment of patients with chronic periodontitis. METHODS: Two quadrants of each of the 12 patients received root planing with diamond burs whereas other 2 quadrants were treated with curettes. Clinical periodontal measurements were recorded at baseline and then 1, 3, 6 months after completion of non-surgical periodontal treatment...

BACKGROUND: There is limited information regarding the profile and outcomes of implant treatment provided in the Australian public sector. This retrospective cohort study reviewed dental implant treatment completed at the Adelaide Dental Hospital over a 20 year period. METHODS: The database of implant treatment completed between 1996 and 2015 was analysed for patient, implant, prosthesis and operator specifics together with known implant status. RESULTS: Three hundred and twenty patients (mean age = 51...

This study evaluated the associations between oral and general health behaviours, self-reported health and quality of life of 75+ year old adults living independently in South Australia METHODS: A cross-sectional study based on a self-report mailed questionnaire was conducted in 590 independently living adults aged 75+ years. Self-ratings of oral health and general health were assessed using single-item global ratings. Quality of life was measured using the Oral Health Impact Profile and the EuroQol instrument for health utility RESULTS: Overall response rate was 78%...

BACKGROUND: Calcium hydroxide is a common endodontic medicament and has an anti-microbial effect by increasing the localized pH within the root canal. However, Enterococcus faecalis has shown some resistance to calcium hydroxide. METHOD: A flow cell apparatus was used to grow an E. faecalis biofilm on dentine discs. Following 4 weeks growth in Todd Hewitt Broth, flow cells were exposed to either a rapid or slow increase to pH 11.5 or 12.5. Cellular viability was determined using serial plating and the number of colony forming units was normalised against the cellular protein content...

Peri-implant squamous cell carcinoma is an uncommon pathological manifestation, whereas peri-implantitis is commonly found in association with dental implants. Both present similarly with loss of supporting soft and hard tissue around dental implants; therefore, a careful differential diagnosis is required. The present case concerns a 62-year-old Japanese man who had a dental implant which had been in the left maxillary incisor region for 4 years who apparently developed peri-implantitis. This did not respond to localized therapy and antibiotics so was referred for specialist surgical management...

BACKGROUND: The aim was to examine the numbers of hours worked and patient visits provided by age and gender of dentists in Australia, and compare with previous estimates to describe trends. METHODS: Data were collected from a random sample (N = 2961) of Australian dentists. Private sector dentists working in clinical practise were included in the analysis. RESULTS: The response rate was 49% (N = 1345 dentists). Hours per year worked and number of patient visits per year were lower for dentists aged 65 years and older compared with younger dentists, and were higher for male compared with female dentists aged 35-45 to 55-64 years...

BACKGROUND: The Index of Dental Anxiety and Fear (IDAF-4C) was introduced to overcome the theoretical and practical shortcomings of previously developed dental fear measures. This new scale has not been tested on population samples other than in its country of origin, Australia. The aim of this study was to validate the IDAF-4C in a different cultural setting and to determine the prevalence and sociodemographic associations of dental anxiety. METHODS: A cross sectional study of a representative New Zealand adult population sample was undertaken...

The purpose of the study is to document a rare case of a peripheral odontogenic fibroma with associated cervical and coronal tooth resorption in a 38 year old woman. Histopathological features are described, the clinical management outlined and follow-up observations over 27 years detailed. The exophytic firm lesion, coral pink in appearance, located on the labial aspect of a maxillary right lateral incisor was excised, fixed in formalin and prepared for histological evaluation. The resorption cavity and adjacent soft tissue were treated by the topical application of trichloroacetic acid prior to restoration with a glass-ionomer cement and subsequent root canal treatment...

Invasive multiple cervical root resorptions after vital tooth bleaching is a rare condition. The aim of this article is to present a case of multiple external cervical root resorptions (ECRR) after a misguided home whitening treatment. A 34 year old male patient presented with slight sensitivity and mobility in several teeth. Despite the manufacturer's recommendations, the patient used a 22% carbamide peroxide-based tooth bleaching gel at home for 4 days consecutively, at night, on the upper and lower arches...

A brain abscess may result when dental infection reaches the brain through contiguous anatomic cavities such as the maxillary sinus, the ethmoid sinus and the orbital cavity. It is an important complication and should be treated aggressively. Such treatment would include the excision of the etiological factor, drainage and adjuvant antibiotic therapy. The present case concerns a 23 year old woman who presented at the General Hospital of Nova Iguaçu with complaints of pain in the right side of the face and was diagnosed with acute sinusitis...

BACKGROUND: Odontogenic infections are a common presentation to emergency departments of Australian hospitals. Due to the limited training in diagnosis and treatment of dental conditions, these patients can present a challenge for the medical practitioner. The objective of this study was to provide an evidence-based approach to the management of odontogenic infections in adults presenting to Royal Perth Hospital. METHODS: A literature search was conducted to identify evidence-based guidelines for the management of odontogenic infections in the tertiary hospital setting...
