Infective endocarditis (IE) is associated with significant morbidity and mortality. The prevention of infective endocarditis, for many years, has involved the identification of at risk patients undergoing medical or dental procedures and the use of pre-procedural antibiotic prophylaxis. However, evidence regarding the effectiveness of such measures is lacking while evidence is mounting for the adverse effects of inappropriate antibiotic use. International guidelines for antibiotic prophylaxis were amended, radically in some cases to reflect this. Subsequent epidemiological observations of IE have shown mixed results, strengthening calls for well conducted randomised control trials, now that there is genuine clinical equipoise among clinicians about this question.

Background and objectives
Microbial biofilm and host susceptibility play an important role in the initiation and progression of periodontitis. Periodontitis is considered the sixth complication of diabetes mellitus and a bidirectional relationship exists between diabetes and periodontitis. This cross-sectional observational study was undertaken to evaluate the glycosylated haemoglobin (HbA1c) level in chronic periodontitis.
Methods
The study involved 100 subjects. The case group consisted of 50 subjects with chronic periodontitis and the control group consisted of 50 periodontally healthy subjects. Periodontal parameters including plaque index, oral hygiene index, modified gingival index, probing pocket depth, and clinical attachment level were measured and recorded. Systemic parameters like Body Mass Index (BMI), Waist Hip Ratio (WHR), C- Reactive Protein (CRP), Glycosylated haemoglobin (HbA1c), lipid profile, fasting blood sugar, post prandial blood sugar and serum albumin were assessed in all subjects.
Results
The mean HbA1C for the case group was 6.27±1.5 and for the control was 5.36±0.4 and the difference was statistically significant (p = 0.001). The mean FBS, PPBS, LDL, WHR, CRP was statistically significant between groups (p ≤0.05). Periodontal parameters like PI, OHI, MGI, PD and CAL were significantly higher in the case group than the control group (p value ≤ 0.05). The multivariate linear regression model with the dependent variable HbA1c showed chronic periodontitis was significantly associated with HbA1c level.
Conclusion
In chronic periodontitis patients (otherwise systemically healthy) the presence of periodontal inflammation affected the glycosylated haemoglobin level and they were in prediabetes stage. Therefore, it is plausible that the prediabetes stage might be reduced via appropriate periodontal therapy.

Background: The ideal goal of periodontal therapy is regeneration of the lost periodontium. However regeneration of the lost interdental papilla has been elusive. Therefore the ability of rebuilding lost papillae in the maxillary segment has become one of the major challenges in periodontal plastic surgery. Objectives of the study: To evaluate the success and predictability of surgical technique using a sub epithelial connective tissue graft interposed in a coronally displaced flap to reconstruct the lost interdental papillae. Methods: The purpose of this study is to evaluate the success and predictability of a surgical technique using a subepithelial connective tissue graft from the palate with coronally displaced flap to regenerate the lost interdental papilla in 11 systemically healthy patients.Results: Post treatment follow up show statistically significant results from baseline to 3months and 6 months. Conclusion: The present study attempted a single surgical procedure to reconstruct the lost interdental papilla using subepithelial connective tissue graft interposed in coronally displaced flap in 11 patients with Tarnow’s class-II papillary recessions. At the end of 6 months it was found that the sites demonstrated significantly superior results as determined by percentage of reduction in the area of the black triangle both clinically (60.26%) and on the model (54.29%). Clinical Implications: Although complete regeneration of interdental papilla was not achieved, the results of this study demonstrate that a predictable and an esthetically pleasing surgical outcome can be achieved in one attempt for class II papillary recessions.

Sinus augmentation is a predictable procedure that is often required when restoring the posterior maxilla with dental implants. Even with high success rates, careful pre-surgical planning is crucial. A 3D model is a valuable aid for the clinician as it allows for pre-operative simulation, which can reduce surgical time, reduce the risk of intra-operative complications and decrease the potential for error. The aim of this case report is to focus on how such a model is useful when undertaking a sinus augmentation procedure with simultaneous implant placement.

Prevalence of peri-implant complication is expected to be on the rise with the increased number of implants being placed. Depending on the degree of osseous involvement, the clinician needs to decide if the treatment goal is to arrest the disease progression, regeneration or explantation and replacement. Host's medical status, defect configuration, aesthetic outcome, ability to access for plaque control post-treatment, and the patient's wishes are key factors to consider. The purpose of this review is to provide a contemporary synopsis on the management of peri-implantitis with emphasis on explantation. Guidance on the identification of factors/situations where salvaging an implant may be less favourable is discussed and the various techniques to remove a fractured, or peri-implantitis-affected non-mobile implant are described.

The palatal injection of anaesthesia is more painful for the patient when compared to other sites of the oral cavity. Pre-cooling (cyro anaesthesia) is a well-known method practiced to reduce pain, with the use of ice or refrigerant spray on the affected site. The already known methods of ice application to the palatal site have few practical drawbacks. Therefore, this technical note highlights the use of an iced cotton bud as a novel way of providing effective pre-cooling for palatal anaesthesia. Commercially available cotton buds were dipped in clean water and then placed in the freezer. Next the frozen cotton bud was placed on the proposed anaesthetic site for one minute and anaesthesia less than 0.5CC local anaesthetic solution was delivered at a slow pace while maintaining pressure using the iced-cotton cotton bud. All patients tested showed a 0 pain response to a visual analogue scale of 0–10. This technique can be valuable to dental practitioners who are aiming for a pain free anaesthetic experience for their patients. There is potential for further research and evaluation of this technique.

Background
Mandibular neurovascular canal contents may be vulnerable to damage during mandibular surgical procedures. Greater knowledge of the location and configuration of the mandibular canal can help in the safe performance of these procedures in the dental clinic. Cross-sectional CBCT imaging is a good modality for studying the course, location, configuration and accessory branches of the mandibular canal. The aim of this study was to observe the branching of the mandibular canal at different segments of the mandible and mandibular tooth groups.
Methods
CBCT images of 116 mandibular halves were included in this study. The presence of secondary branching of the mandibular canal in the ramus, retromolar area, molar and premolar teeth as well as the length, diameter and angle of these branches were observed.
Results
sixty nine mandibular halves (59.5%), had a main canal with no branching, There were 36 IAC (31%) with one, 8 (6.9%) with two, 2 (1.7%) with three and 1(0.9%) with 5 accessory branches. Of these secondary branches, 16 (25.4%) were in the ramus, 16(25.4%) in the retromolar, and 31(49.2%) in the molar regions.
Conclusion
Advanced cross-sectional imaging modalities especially CBCT is a suitable tool for observing anatomic characteristics of mandibular canal to preserve this vital structure in surgical procedures.

Background
To quantify participation in dental research activities in Malaysia, and investigate its association with socio-demographic and professional characteristics, and perceptions of research and development (R&D) culture.
Materials and methods
Dental academics in Malaysian dental schools were invited to complete a questionnaire by email and post. The survey comprised questions on research activities in the past 12 months, socio-demographic and professional characteristics, and the R&D Culture Index. Principal components factor analysis was carried out to confirm the factor structure of the R&D Culture Index. Chi-square test was used to identify association of research activities with R&D culture, and socio-demographic and professional characteristics. Binary logistic regression was carried to identify predicators of research activities.
Results
Of 256 potential participants contacted, 128 (50%) useable responses were returned. Three R&D Culture factors accounting for 57.4% of variance were extracted. More positive perception of R&D Support was associated with Malaysians (0.025) and those employed in Government schools (0.017). R&D Skills and Aptitude were associated with older respondents (0.050), PhD qualification (0.014) and more years in academia (0.014). R&D Intention was associated with any of the socio-demographic characteristics. Thirty (23.4%) respondents reported a peer-review research publication in the past 12 months, which was associated with having a PhD (OR 12.79, CI 1.28–127.96), after adjustment in regression analyses.
Discussion
Postgraduate research training should be encouraged to promote participation in research activities. R&D culture did not appear to impact on research productivity. Other factors such as individual attitudinal interests should be studied.
量化马来西亚牙科研究活动的参与情况,并调查其与社会人口统计学和专业特征的关系,以及对研究和发展(R&D)文化的看法。材料和方法邀请马来西亚牙科学校的牙科学者通过电子邮件和邮寄方式填写问卷。该调查的问题包括过去12个月的研究活动、社会人口和专业特征,以及研发文化指数。通过主成分因子分析,确定了研发文化指数的因子结构。使用卡方检验来确定研究活动与研发文化、社会人口统计学和专业特征的关联。采用二元逻辑回归来确定研究活动的预测因子。结果在联系的256名潜在参与者中,获得了128份(50%)可用回复。提取了三个R&D Culture因子,占方差的57.4%。马来西亚人(0.025)和在公立学校工作的人(0.017)对研发支持有更积极的看法。研发技能和天资与受访者年龄(0.050)、博士学历(0.014)和学术资历(0.014)相关。R&D意向与任何社会人口统计学特征都有关联。30名(23.4%)受访者在过去12个月内发表过同行评议的研究论文,经回归分析调整后,这与拥有博士学位相关(OR 12.79, CI 1.28-127.96)。应该鼓励研究生的研究训练,以促进他们参与研究活动。研发文化似乎对研究效率没有影响。其他因素,如个人的态度兴趣也应加以研究。
