The belief that a woman's dental health is likely to deteriorate through having children remains common and may originate from the old wives' tale "a tooth per child". As recently as 2005, about 1 in 5 US mothers believed this.1 Epidemiological studies have suggested an association between parity (the number of times a women has given birth) and tooth loss,2-5 and parity and periodontal attachment loss,6 but none has determined whether this association is causal. A number of studies have reported greater severity and extent of gingival inflammation during pregnancy...

BACKGROUND: Literature has shown dentists tend to overprescribe antibiotics and do not always prescribe in accordance with recommended guidelines. Unnecessary prescribing is one major factor that contributes to the development of antibiotic resistance. The aim of the present study was to assess the antibacterial prescribing patterns of dentists in Australia from 2013 to 2016. METHODS: Data on dental antibacterial prescriptions dispensed under the Pharmaceutical Benefits Scheme (PBS) from 2013 to 2016 was accessed and prescribing trends analysed...

This study aimed to gain insight into common practices of Australian prosthodontists when placing a post in an endodontically treated tooth (ETT). A 17-question open- and closed- format questionnaire was sent to registered Australian prosthodontists. The response rate was 55% (n=95). The majority of respondents indicated the purpose of a post was to retain a core (n=94, 99%). The decision to place a post is affected by the quantity of remaining tooth structure (n=91, 96%) and the definitive restoration (n=68, 72%)...

BACKGROUND: Significant developments have occurred in the design of resin bonded bridges (RBBs) over the past two decades. They are commonly used as an alternative treatment option for a single missing tooth. The longevity of these bridges needs to be further investigated to evaluate long term outcomes for this option to remain relevant. METHODS: A cohort of patients who received anterior resin bonded bridges (ARBBs) over two decades was studied retrospectively...

BACKGROUND: Retainers are commonly used to maintain post-orthodontic occlusion stability. We aimed to determine post-fabrication thickness and thinning rate of thermoformed retainers. MATERIALS AND METHODS: Forty-eight retainers were fabricated from polyethylenterepthalat-glycol copolyester or polypropylene blanks, using vacuum- or pressure-thermoforming. Retainer thickness was measured at multiple locations. RESULTS: Thinning rate had a broad range: the mid-labial incisor region of 1mm polyethylenterepthalat-glycol copolyester pressure-thermoformed mandibular retainers had the greatest thinning rate (68...

BACKGROUND: Maternal behaviours during pregnancy are likely to play a significant role in the development of dental caries in children. Although midwives are well placed to discuss oral health and provide information to women, dental attendance by women during pregnancy is minimal. This study aimed to explore midwives' experience of facilitating pregnant women's access to dental care and to document women's experience of receiving dental information and care during pregnancy. METHODS: Focus groups with midwives and telephone interviews with women, who were referred to Monash Health Dental Services, were conducted to explore their perspectives and experiences...

BACKGROUND: To evaluate changes in xerostomia status, salivary characteristics and gland volumes two years following radiotherapy in nasopharyngeal carcinoma patients. METHODS: Xerostomia scores, salivary flow rates, pH and buffering capacity were measured at pre-radiotherapy, mid-radiotherapy, two-weeks, three-months and two-years post-radiotherapy. Salivary gland volumes and their correlation with radiation dose were also assessed. RESULTS: Mean radiation dose to oral cavity, parotid and submandibular glands was 44...

BACKGROUND: The aim of this study was to investigate for the first time the histological response of human periodontium to mineral trioxide aggregate (MTA) and Biodentine. METHODS: Six patients scheduled for implant full-arch rehabilitation were randomly assigned to one of the two test groups: MTA or Biodentine treatment. For each patient, two teeth scheduled for strategic extraction were randomly assigned either to the test or to the control treatment. A lateral perforation was drilled on the root and either repaired with MTA/Biodentine or filled with gutta-percha(control)...

Facial Osteotomy techniques have evolved enormously over the past 20 years providing significant and often life-changing benefits to our dental patients with skeletal malocclusions. Advancements in technology and refined surgical techniques have resulted in improvements in surgical outcomes, a reduction in post-operative complications and a quicker recovery for today's patients undergoing orthognathic surgery. This paper aims to an update on the contemporary approach to the correction of skeletal malocclusions with facial osteotomies...

Dental implants have been a routine part of dental practice for many years and are performed by a variety of practitioners with different backgrounds and training. This paper will outline the principles and practical surgical aspects of 'simple' implant placement against a background of our current understanding of the literature that informs our surgical procedures. Implants need to be placed in a restoratively suitable position surrounded by sufficient bone, draped in adequate keratinised soft tissue and sufficiently separated from one another and the adjacent teeth...

The atrophic and edentulous jaw can pose a number of challenges for the implant clinician. In simple terms, the amount of bone that remains is insufficient for the conventional placement of a dental implant. A variety of treatment strategies can be employed to enable implants to be placed despite the paucity of bone stock in either the mandible or the maxilla. Conceptually these strategies follow one of two pathways: either augmentation of the bone, or the novel utilization of the remaining bone. This article will discuss patient assessment, treatment planning, and the range of contemporary options available to enable fixed implant based rehabilitation of each jaw...

The complexity of the craniofacial patient mandates the cooperation of a multidisciplinary team that can systematically evaluate each individual and ensure that a protocol-driven pathway is undertaken for the best patient care. Oral and maxillofacial surgeons contribute to surgical care in this setting with specific knowledge of growth and development of the face. This enables optimum timing for early skeletal correction where appropriate, and definitive surgery following the cessation of growth to maximize function and aesthetics...
