Background: General dental practitioners often perceive root canal treatments as complex, and specialist referrals are commonplace in general dental practice. Therefore, the aim of this study was to better understand the knowledge of Australian general dentists and their attitudes regarding endodontics in general, and specifically (RCT), to highlight barriers and facilitating factors in the provision of endodontic care.

Methods: A combined paper-based and online survey was sent to general dental practitioners. Read More

Medication-related osteonecrosis of the jaws (MRONJ) is a painful debilitating condition which is considered rare in the medical literature available to prescribers. Dentists, however, are likely to trigger this condition through extractions and implants. Anecdotally MRONJ appears more common than first thought. Read More

Macrodontia is a relatively uncommon dental anomaly and has often been reported to occur in association with other dental anomalies. Significant orthodontic and restorative challenges may arise in the management of patients with macrodont teeth. This case report demonstrates the opportune and carefully considered management of a patient presenting with both a macrodont and a supernumerary incisor tooth. Read More

This case series presents two asymptomatic cases of juvenile angiofibroma which were initially incidentally identified in pre-orthodontic radiographs. Juvenile angiofibroma is an uncommon, locally aggressive benign, vascular neoplasm with invasive growth patterns. Due to the hypervascularity of these tumours, there are biopsy associated risks and multi-slice computed tomography, magnetic resonance imaging and angiography are usually employed for diagnosis.

The goal of this systematic study was to compare the survival rate (SR), marginal bone loss (MBL) and clinical complications between extra-short implants (≤6 mm) and 6-mm-longer implants in randomized clinical trials. A systematic electronic and manual search was performed using the PubMed, Web of Science, Scopus and DOAJ databases. A meta-analysis was conducted to compare the SR and MBL between both groups.

This case report describes the presentation of a pregnant woman, a periodontist, at 39 weeks gestation to The Royal Prince Alfred Hospital emergency department (Sydney, NSW) with major haemorrhage from an oral arteriovenous malformation (AVM) and foetal distress. The lesion had grown rapidly during her pregnancy and she had presented to multiple hospitals and dental practitioners who had failed to diagnose her condition and recognize the potential for major complications for the patient and her baby. Bleeding was controlled with manual pressure while she underwent an emergency Caesarean section followed by emergency angiography and partial embolization of the lesion. Read More

Background: Occlusoproximal restorations of primary molars usually fail, so it is necessary to investigate new materials that may overcome this challenge. Thus, this trial aimed to evaluate the longevity of occlusoproximal ART restorations in primary molars using a glass ionomer cement - GIC (Equia Forte - GC Corp) and a Giomer resin composite - GCR (Beautifil Bulk Restorative - Shofu Inc) after 24 months.

Methods: One hundred and eighty-two (182) children aged from 4 to 8 years were selected and randomly assigned to GIC or GCR. Read More

Fluoride has been shown to be an effective agent in the prevention of caries during orthodontic treatment. Resin-modified glass-ionomer cements possess therapeutic anticariogenic properties acting as a fluoride reservoir and releasing fluoride into the environment, particularly at low pH where there is a threat of enamel demineralisation and white spot lesions (WSL's). Patient compliance to instructions in standard oral hygiene measures limits the success of caries prevention and the routine use of glass-ionomer cements can mitigate the lack of compliance, although RMGIC's are not a panacea against WSL's.

Hypovitaminosis C, or scurvy, is thought to be an uncommon condition. Although prevalent in the 19th century, its ease of absorption and availability in a general diet has greatly reduced its incidence. Vitamin C is necessary for a number of physiological processes and deficiency can result in a number of complications including bleeding/bruising, anaemia and gingival hyperplasia. Read More
