Background: Hawley retainers (HRs) and vacuum formed retainers (VFRs) are the most commonly used removable retainers in the orthodontic practice. Patients' cooperation in wearing these appliances is affected by the levels of discomfort and oral impairment. The evidence regarding their acceptably among orthodontic patients is limited. Aims: To compare the acceptability of HRs and VFRs over a 6-month period in a group of fixed orthodontic patients. Trial Design: Two-arm parallel-group randomized controlled trial...

Background: Cerebral abscess is a recognised complication of pulmonary arteriovenous malformations (PAVMs) that allow systemic venous blood to bypass the pulmonary capillary bed through anatomic right-to-left shunts. Broader implications and mechanisms remain poorly explored. Methods: Between June 2005 and December 2016, at a single institution, 445 consecutive adult patients with CT-scan confirmed PAVMs (including 403 (90.5%) with hereditary haemorrhagic telangiectasia) were recruited to a prospective series...

BACKGROUND: Biological hydroxyapatite (HA), has several mechanical and physical advantages over the commercially available synthetic apatite (CAP-HA). The aim of this in vivo study was to investigate the effect of osteoinductive "bone-like hydroxyapatite" obtained from simulated body fluid (SBF) combined with osteoinductive "boron" (B) on bone healing. MATERIALS: Bone like nanohydroxyapatite (SBF-HA) was precipitated from 10× simulated body fluid (10×SBF). Thirty Sprague-Dawley rats were randomly divided into 5 experimental groups (n = 6 each)...

BACKGROUND: Keratin has shown promising outcomes as a biomaterial due to its inherent bioactivity, biocompatibility and regenerative effects. The effect of keratin on repair and regeneration of dental tissues has never been studied before. Current therapies to treat pulp tissues involve its replacement with inert, synthetic materials that do not have a proper biological function, leading to failure and tooth loss. This study aimed to develop a biocompatible keratin hydrogel (KH) suitable for pulp therapies...

Objectives We explored the real cost of training the workforce in a range of primary health care professions in Australia with a focus on the impact of retention to contribute to the debate on how best to achieve the optimal health workforce mix. Methods The cost to train an entry-level health professional across 12 disciplines was derived from university fees, payment for clinical placements and, where relevant, cost of internship, adjusted for student drop-out. Census data were used to identify the number of qualified professionals working in their profession over a working life and to model expected years of practice by discipline...

BACKGROUND: Early language skills are critical for later academic success. Lower socioeconomic status (SES) children tend to start school with limited language skills compared to advantaged peers. We test the hypothesis that this is due in part to differences in caregiver contingent talk during infancy (how often the caregiver talks about what is in the focus of the infant's attention). METHODS: In a randomised controlled trial with high and low SES families, 142 11-month olds and their caregivers were randomly allocated to either a contingent talk intervention or a dental health control...

Periodontics cannot be practiced in isolation as frequently many patients have multiple dental needs or medical health issues requiring management. In addition, pathology may manifest in the periodontal tissues, and the onset and progression of periodontitis can be affected by systemic conditions, such as diabetes, and vice versa. The focus of this volume of Periodontology 2000 is interdisciplinary periodontics, and the articles included discuss the interactions and the interrelationshipbetween periodontal tissues/periodontal diseases and endodontics, fixed prosthodontics, implant dentistry, esthetics, gerodontology, radiology, orthodontics, pediatric dentistry, oral and maxillofacial surgery, oral pathology, special needs dentistry and general medicine...

Dental implants are regularly placed in patients with a history of periodontitis, even though peri-implant tissues are susceptible to the same host-modulated plaque-induced factors that initiate and sustain periodontitis. This article endeavors to clarify the evidence regarding the history of periodontitis as a risk factor for implant success and survival, and the role of supportive periodontal therapy in maintaining implants for individuals with a history of periodontitis.

In many countries, dental services, unlike other health-care services, are not covered by the principle of universal access. It is only in the last couple of decades that there has been a greater interaction between medicine and dentistry. Various health-care systems worldwide may provide public dental services to the young and the disadvantaged, but few provide access to all. Public policy does not appear to appreciate the vast economic, health and social implications of poor oral health on the overall health of an individual...

Endodontic-periodontal lesions present challenges to the clinician regarding diagnosis, treatment planning and prognosis. Etiologic factors, such as bacteria and viruses, as well as contributing factors, such as trauma, root resorptions, perforations, cracks and dental malformations, play an important role in the development and progression of such lesions. Treatment and prognosis of endodontic-periodontal lesions vary, depending on the etiology, pathogenesis and correct diagnosis of each specific condition...

The oral health of children and adolescents mirrors their general health. Because oral health care is often delivered in isolation from general health care, oral signs and symptoms do not always alert practitioners to their significance beyond the mouth. An important example of this is the association of a higher risk of dental caries and periodontal disease in children and adolescents with overweight, obesity and prediabetic conditions. Oral-health practitioners need to consider the health conditions that their patients may have...

Esthetic considerations are a significant contributing factor in the management of prosthodontic cases and an interdisciplinary approach is often necessary to achieve an optimal result. The visible soft-tissue architecture plays a key role in developing an esthetic smile. Furthermore, an understanding of the relationship between the restorative margin and the gingiva is important for long-term stability of the result. The gingival architecture and gingival health are important for ensuring optimal esthetics following prosthodontic work and close attention to both soft and hard tissues around the teeth, before, during and after restorative procedures, will greatly improve the likelihood of a successful outcome...

Surgical procedures of the oral cavity can be performed by a number of dental specialists and clinicians. Because of the limited number of surgical procedures that can be performed inside the oral cavity, the boundaries between specialties may become indistinct and lead to confusion for general dentists in terms of patient referrals. In this article, what the two surgical specialties of dentistry (i.e. periodontology and oral and maxillofacial surgery) have to offer is highlighted, together with clinical examples to illustrate the interdisciplinary relationship between them...

The present literature review is focused on two main areas: (i) periodontal conditions in older individuals; and (ii) the scientific data available on periodontal treatment outcomes in individuals ≥ 75 years of age. The population of older people is increasing but the data on periodontal therapies and their efficacy in this population are limited and need to be carefully reviewed. Although life expectancy has increased, this does not mean that older people are medically healthy. Several chronic systemic diseases are associated with periodontitis, and the prevalence of most chronic diseases increases with age...

Contemporary periodontal therapy has evolved to become more interdisciplinary and increasingly involves more complex treatments, including bone and soft-tissue regenerative procedures. Therapeutic options require an imaging modality or combination of techniques that are capable of providing a diagnostic osseous baseline and facilitating quantification of smaller increments of bony change, both loss and additive, which are comparable over time. Intra-oral and panoramic radiography are the modalities most commonly used to identify the location, quantify the amount and the pattern of alveolar bone loss and determine response to therapy...

Individuals with special needs are at more risk of dental disease, including periodontal diseases, and have a greater prevalence and incidence of periodontal diseases than the rest of the population. Genetic or medical conditions, and/or the use of prescription medication or recreational substances, may further increase the risk for susceptibility to periodontal disease. The success of preventing or controlling periodontal diseases amongst this group of patients has not been established. Even those individuals who access regular and comprehensive dental care appear to develop periodontal diseases as they age, and this development occurs at a rate comparable to the natural history of the disease...

Fluoride-induced ameloblast apoptosis is a key event in dental fluorosis development. Forkhead box o1 (Foxo1) is a transcription factor involved in cell apoptosis. The present study aims to investigate the effect of Foxo1 on ameloblast apoptosis induced by fluoride in vitro and to explore its possible mechanism. Ameloblast-like cells (LS8 cells) were exposed to various concentrations of NaF for up to 48 h. Foxo1 activation was modulated using lentiviral vectors, and cell apoptosis was measured by flow cytometry...
