Abstract: There has been an increase in the availability of oral health therapists (OHTs) in the oral health workforce in the last decade. The impact these clinicians will have on the oral health of the general public is dependent on access pathways and utilization. This study aimed to profile Australian dentists who employ or are willing to employ OHTs and to explore the degree of association between dentist characteristics and employment decisions. This cross-sectional study used a random s le of Australian dentists (n = 1169) from the Federal Australian Dental Association register in 2009. Participants were sent a postal questionnaire capturing dentist characteristics and oral health practitioner employment information. An adjusted response rate of 55% was obtained. Dentists willing to employ OHTs included non-metropolitan dentists, dentists in multiple surgery practices and those considering practice expansion. Age, gender and sector of practice were not significantly associated with retrospective employment decisions or willingness to employ in the future. Certain characteristics of dentists or of their practice are associated with their history of employment and willingness to employ OHTs. Employment decisions are more commonly related to entrepreneurial aspirations (expressed as a willingness to expand), sector of practice, surgery capacity and regionality over gender and age. Understanding the factors that influence the employment of OHTs is important in enhancing access pathways to the services provided by OHTs.

Abstract: This brief report documents teaching practice that has facilitated deeper connections between Bachelor of Oral Health (BOH) students at The University of Adelaide and community support agencies to promote increased health literacy and confidence to seek care amongst marginalised populations. The aim was to increase the capacity of marginalised groups “to access, understand, appraise and apply information to make effective decisions about health and health care” (Australian Commission on Safety and Quality in Health Care. Hlth Lit 2014. Available from: www.safetyandquality.gov.au/standards/nsqhs‐standards artnering‐consumers‐standard/health‐literacy . Accessed January 21, 2020). The health promotion curriculum in the BOH course at The University of Adelaide encourages students to focus on health literacy, equity and partnerships in the development of several small targeted health promotion programs. Students co‐create, implement and evaluate these programs, engaging community groups, supportive partners and industry stakeholders in a range of unique ways. Sustainable relationships have been established and are growing with partner organisations. As these relationships strengthen, so too does the trust, creative licence, innovation and promotion of the students’ involvement directly or indirectly with community. That leads to more frequent touch points with community and greater community buy‐in. As familiarity increases, so too does community health literacy and confidence to enter oral health care pathways. Strategically planned activity outside of dental setting has the potential to draw community members and dental service providers together, with the enhancement of health literacy and access amongst at‐risk populations, an important by‐product. There seems great potential for further benefits to be realised by oral health students and members of the public when there is multi‐stakeholder involvement in co‐created health promotion initiatives, that see students further engage with community outside clinical environments.

Abstract: PTEN (phosphatase and tensin homologue deleted on chromosome ten) proteins are dual phosphatases with both protein and phosphoinositide phosphatase activity. They modulate signalling pathways controlling growth, metabolism and apoptosis in animals and are implied in several human diseases. In the present paper we describe a novel class of PTEN pro-teins in plants, termed PTEN2, which comprises the AtPTEN (Arabidopsis PTEN) 2a and AtPTEN2b proteins in Arabidopsis. Both display low in vitro tyrosine phosphatase activity. In addition, AtPTEN2a actively dephosphorylates in vitro the 3′ phosphate group of PI3P (phosphatidylinositol 3-phosphate), PI(3,4)P2 (phosphatidylinositol 3,4-bisphosphate) and PI(3,5)P2 (phosphatidylinositol 3,5-bisphosphate). In contrast with animal PTENs, PI(3,4,5)P3 (phosphatidylinositol 3,4,5-trisphosphate) is a poor substrate. Site-directed mutagenesis of AtPTEN2a and molecular modelling of protein–phosphoinositide interactions indicated that substitutions at the PTEN2 core catalytic site of the Lys267 and Gly268 residues found in animals, which are critical for animal PTEN activity, by Met267 and Ala268 found in the eudicot PTEN2 are responsible for changes in substrate specificity. Remarkably, the AtPTEN2a protein also displays strong binding activity for PA (phosphatidic acid), a major lipid second messenger in plants. Promoter::GUS (β-glucuronidase) fusion, transcript and protein analyses further showed the transcriptional regulation of the ubiquitously expressed AtPTEN2a and AtPTEN2b by salt and osmotic stress. The results of the present study suggest a function for this novel class of plant PTEN proteins as an effector of lipid signalling in plants.

Abstract: Used routinely by dental practitioners, local anaesthetics are generally a safe and effective means of achieving pain control during invasive dental procedures. Delivery, however, is technique sensitive and the potential for patient complication exists. Although reasonably rare, ocular complications have occurred, often leaving the patient and the clinician in distress. Such reported events have almost always involved tissue responses ipsilateral to the injection site. The current case report presents an unusual event involving involuntary fasciculation or hemifacial spasm and eventual eyelid closure on the contralateral side following a routine inferior alveolar nerve block. Aspects including the patient's history, the observed response, a pathophysiological hypothesis and patient management are discussed.

Abstract: Two-month-old tomato plants were submitted to day/night cycles and to prolonged darkness in order to investigate the physiological and biochemical response to sugar starvation in sink organs. Roots appeared particularly sensitive to the cessation of photosynthesis, as revealed by the reduction of the growth rate and the decline of the carbohydrate and protein content. Therefore, excised tomato roots were used as a model to deepen the characterization of sugar starvation symptoms. In excised roots, the endogenous sugars were rapidly exhausted and significant degradation of protein was observed. Glutamine and asparagine accounted for most of the nitrogen released by protein breakdown. Respiration declined and proliferation- and growth-associated genes were repressed soon after the beginning of the sugar depletion. Among the genes studied, only the gene encoding asparagine synthetase was strongly induced. All the starvation symptoms were reversible when the roots were resupplied with sugar. When the culture conditions deteriorated, the metabolic and molecular changes led to the triggering of apoptosis of the root cells.
