Abstract
AIM The aim was to assess two macronutrient interventions in a 2x2 factorial dietary design to determine their effects on oral health. MATERIALS AND METHODS Participants (65-75 years old) with a BMI between 20-35 kg/m2 of a larger RCT who consented to an oral health assessment were recruited. They had ad libitum access to one of four experimental diets (omnivorous higher fat or higher carbohydrate, semi-vegetarian higher fat or higher carbohydrate) for 4 weeks. Periodontal examination included periodontal probing depth (PPD), clinical attachment level (CAL) and bleeding on probing. Oral plaque and gingival crevicular fluid (GCF) were collected before and after the intervention. RESULTS Between baseline and follow up the number of sites with a CAL <5 mm (mean difference (MD) -5.11±9.68, P=0.039) increased and the GCF amount (MD -23.42±39.42 Periotron Units (PU), P=0.050) decreased for the semi-vegetarian high fat diet. For the mean proportion of sites with PPD reduction >1 mm and CAL gain >1 mm significant differences were calculated between the diets investigated. The clinical parameters were not associated with changes of the oral microbiota. CONCLUSION The results of this study provided evidence that a semi-vegetarian higher fat diet provides benefits to clinical parameters of periodontal health. ACTRN12616001606471.

Abstract
Various preclinical methodologies have been adopted by dental and oral health programs to develop student competence in administering dental local anesthetics (LA). Student-to-student practice is the most common preclinical training method. However, manikin simulation models have been introduced to avoid possible complications and ethical concerns with student-to-student injections. In 2017, the methodology was changed in the Bachelor of Oral Health program at The University of Sydney School of Dentistry in Australia from student-to-student practice to manikin simulation models. The aim of this study was to compare the students' learning experience, perceived confidence, and anxiety in giving their first injections to patients in these two preclinical training methods. A mixed-methods cohort design was used to compare the 2016 (n = 42) and 2017 (n = 32) oral health students' experiences and perceptions and evaluate students' clinical experience after commencing LA practice on patients. Students completed a questionnaire about their perceived level of confidence and anxiety before and after their first LA to a child and an adult for both infiltration and inferior alveolar nerve b lock (IANB) injections. Focus groups were conducted to further investigate the students' experience. The results showed that the perceived confidence and anxiety of the two cohorts did not differ significantly from each other. Although students found it difficult to transition into clinical practice without having experienced LA themselves, the manikin simulation practice provided a safe learning platform that avoided ethical and legal concerns. These findings support the use of manikin simulation models as an alte rnative method for dental local anesthetic preclinical training.

Abstract
While there is a burgeoning interest in the effects of nutrition on systemic inflammatory diseases, how dietary macronutrient balance impacts local chronic inflammatory diseases in the mouth has been largely overlooked. Here, we used the Geometric Framework for Nutrition to test how the amounts of dietary macronutrients and their interactions, as well as carbohydrate type (starch vs sucrose vs resistant starch) influenced periodontitis-associated alveolar bone height in mice. Increasing intake of carbohydrates reduced alveolar bone height, while dietary protein had no effect. Whether carbohydrate came from sugar or starch did not influence the extent of alveolar bone height. In summary, the amount of carbohydrate in the diet modulated periodontitis-associated alveolar bone height independent of the source of carbohydrates.

Abstract
OBJECTIVE Good clinical skills are crucial for all dental practitioners. The transfer of knowledge from didactic lectures to daily clinical application can be challenging for current millennial learners. This study aimed to evaluate the effectiveness of using instructional videos to teach dental local anaesthesia in an undergraduate oral health programme in 2017. METHODS The philosophical basis of this study relies on the Advanced Trauma Life Support (ATLS) course which has been proven effective in practical education. Video clips were made in 3 different formats, with the addition of a quiz-embedded version to reinforce learning and revision for practical assessments. RESULTS All the students agreed that their motivation to watch the videos was to refresh their memories before assessments. 90% of students agreed the videos helped them to learn psychomotor skills that required accuracy. There was a statistically significant correlation between the number of views of the videos on the administration of block injections and the marks received for practical assessment (r = 0.36, P = 0.05), and correlation between participating in online quizzes and theory assessment (r = 0.371, P = 0.044). Videos with narration and background music were found to be popular amongst oral health students. CONCLUSION The use of instructional videos has been found effective in complementing the ATLS approach for teaching psychomotor skills in the administration of local anaesthetics by oral health students. Further studies are required to measure the students' retention of knowledge and application of skills on a patient in clinical settings.

Abstract
Effective dental local anesthetic administration forms the basis of pain-free dentistry; therefore, the application of theoretical knowledge and the ability to deliver injections safely and competently are vital aspects of student learning. Student- to-student administration of the first local anesthetic injection has been a traditional method for preclinical training. The aim of this study was to evaluate oral health students' perceived value of such practice and the impact on their level of anxiety and confidence in giving their first injections to patients. A sequential mixed-methods cohort study design was used. After their local anesthesia training, all 42 second-year students in the oral health program at the Sydney Dental School, University of Sydney, Australia, in 2016-17 were asked to complete five short questionnaires. All 42 students completed each questionnaire, after which seven of them participated in a voluntary focus group. The students reported that they valued the one-on-one feedback from the educators during student-to-student preclinical training. The students' primary concern was the possible pain and discomfort that may arise when they perform the first infiltration or inferior alveolar nerve block injections on patients. Most students reported they felt "a little nervous" and experienced a similar level of confidence in administering the two types of injections. The oral health students valued the experiential learning of student-to-student preclinical dental local anaesthetic training. Students' level of anxiety and confidence was affected by the age of patients and type of local anesthetic injections. The level of anxiety students experienced was negatively correlated with their confidence in giving first local anesthetic injections to patients. Further investigation is needed to determine if this level changes with more clinical experience.

Abstract
Periodontitis is a chronic inflammatory disease of the supportive tissues and bone surrounding the teeth. In severe cases, it can consequently lead to tooth loss. This disease is most prevalent in rural and remote communities where regular dental visits are limited. Hence, there's a need for a periodontal screening tool for use by allied health professionals outside of dental clinics to detect periodontitis for early referral and intervention. In this paper two algorithms have been proposed and applied on two independently collected datasets in Germany and Australia with 20 and 24 participating subjects respectively; in the first algorithm, intra-oral images of before periodontitis treatment have been considered as diseased subjects and the images of after treatment have been considered as healthy subjects. Using the histogram of pixel intensity as our classification feature, the healthy and diseased subjects have been classified with an accuracy of 66.7%. In the second algorithm, using the difference between the histograms as our classification features, images of "before" and "after" treatment have been classified with an accuracy of 91.6%. If used in a smart phone application, the first algorithm can help people with limited access to dental clinics to be screened for periodontitis by allied health professionals in any healthcare setting. The second algorithm may be useful in helping non-dental personnel to monitor the progress of periodontal treatment.

Abstract
AIMS This retrospective observational study examined the association between International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM)-coded outpatient hypoglycaemic events and fall-related fractures in Medicare-covered patients with type 2 diabetes. METHODS Data were derived from healthcare claims for individuals with employer-sponsored Medicare supplemental insurance. The study period consisted of two consecutive 1-year periods; the baseline period (1 April 2008 to 31 March 2009) and the evaluation period (1 April 2009 to 31 March 2010). Patients selected for study were at least 65 years of age with evidence of type 2 diabetes during the baseline period, as identified using a Healthcare Effectiveness Data and Information Set algorithm or by at least two prescription claims for oral antidiabetic drugs. The baseline period was used to collect information on the patients' demographics and clinical characteristics. The evaluation period was used to identify the presence of hypoglycaemic events and fall-related fractures. Logistic regression was employed to examine the association between hypoglycaemic events and fall-related fractures occurring during the evaluation period, adjusting for patients' demographics and clinical characteristics. RESULTS Of 361 210 included patients, 16 936 had hypoglycaemic events during the evaluation period. Patients with hypoglycaemic events had 70% higher regression-adjusted odds (hypoglycaemic events odds ratio = 1.70; 95% confidence interval = 1.58-1.83) of fall-related fractures than patients without hypoglycaemic events. Multiple sensitivity analyses also yielded results suggesting increased odds of fall-related fractures in patients with hypoglycaemic events. CONCLUSIONS ICD-9-CM-coded outpatient hypoglycaemic events were independently associated with an increased risk of fall-related fractures. Further studies of the relationship between hypoglycaemia and the risk of fall-related fractures are warranted.

Abstract
Experience is presented of the treatment of 100 patients for routine dentistry in general dental practice under propofol (Diprivan) sedation, delivered by continuous infusion. The infusion rates were set manually according to patients' responses. There were no differences in dental treatment or propofol requirements according to gender. Propofol requirements in some cases exceeded the upper limit of the recommended dose ranges and reasons why this may have occurred are discussed. A most useful feature of propofol sedation was the associated rapid recovery, with no patients needing to remain in the surgery for the purposes of recovery. The technique met with patients' approval, as all responses returned indicated a willingness to undergo the same type of sedation in future. Propofol sedation is not appropriate for the single operator/sedationist.

Abstract
OBJECTIVE This study was carried out to examine the effectiveness of topically applied bupivacaine 0.25% with adrenaline 1:200,000, for post-operative analgesia in children undergoing dental extractions under general anaesthesia. DESIGN Randomised double blind study in a single centre. SETTING An outpatient dental clinic in a district general hospital, in England, in 1997. SUBJECTS AND METHODS Subjects were selected from children of age 7-15 years having six or less extractions, and randomised using the closed envelope technique. INTERVENTIONS The local anaesthetic used was bupivacaine 0.25% with adrenaline 1:200,000. MAIN OUTCOME MEASURES Children were asked on waking from the anaesthetic whether they had pain or not. Pain was reassessed five and ten minutes post application of swabs to determine any changes in pain. RESULTS Forty-eight children were recruited, of these 18 had no pain post-operatively and 6 were withdrawn due to a lack of cooperation. Twelve children were randomised to each group. There were 6 boys and 6 girls in the bupivacaine group (age 7-15 years), and 4 boys and 8 girls in the saline group. Bupivacaine 0.25% with adrenaline soaked swabs resulted in a significant reduction in pain in 10 children at 10 minutes (P = 0.01). CONCLUSION Bupivacaine 0.25% with adrenaline 1:200,000, on application to exposed sockets is a simple technique that may provide useful post-operative analgesia.

Abstract
This study compared the quality of anaesthesia and surgical access afforded by two techniques for the administration of anaesthesia during paediatric chair dental procedures. A total of 50 ASA 1 paediatric day case patients were randomly assigned to receive anaesthesia through either the traditional Goldman nasal mask or through a nasopharyngeal airway. Patients in the nasal mask group were judged to have significantly worse airway patency (p = 0.0001) and significantly more episodes of airway obstruction (14 vs. 4; p = 0.0032) than those in the nasopharyngeal airway group. Anaesthetic, surgical and oxygen saturation data did not differ significantly between the two groups. Operating conditions were universally graded as excellent in the nasopharyngeal airway group, while those in the nasal mask group were graded as excellent/good in only 79% of cases (p < 0.0001). These results suggest that better quality anaesthesia and operating conditions can be achieved by using a nasopharyngeal airway rather than the traditional nasal mask for the administration of anaesthesia to paediatric chair dental patients.

Abstract
The objective of this double blind study was to compare the sedation following the intravenous injections of midazolam in three dose levels (0.07, 0.10 and 0.15 mg/kg), and to assess the time taken after each dose to return to street fitness. Recovery was monitored by measurement of reaction time. The mean results for each dose were compared against placebo and each other using the Student's t-test. All doses gave a significant (p less than 0.05) lengthening of reaction time compared to placebo. The two highest doses gave similar results when compared to 0.07 mg/kg, but not when compared to each other. Reaction times always returned to control values within 3 hours of injection. The Deletion of Ps test was also employed. A significant correlation was found between the results of reaction time testing and the Deletion of Ps test.
