评估有缺血性心脏病病史患者在牙科手术期间肌钙蛋白水平的早期变化

Background and Aim: This study assessed the salivary calcium level, salivary flow rate, and dental problems of patients with Sjogren's syndrome.Materials and Methods: This case-control study was conducted on 30 patients with Sjogren's syndrome and 30 healthy controls.The salivary flow rate, salivary calcium level, and the decayed, missing, and filled surfaces (DMFS) index were recorded.The total salivary concentration of calcium was assessed by atomic absorption spectrometry using Arsenazo III calcium-sensitive dye.The Kolmogorov-Smirnov test, the parametric independent t-test, and the Mann Whitney U test were used to compare the variables between the two groups.The Pearson's and the Spearman's correlation coefficients were used to analyze the relationship between quantitative variables.Results: The salivary calcium level was insignificantly higher in the case group (4.44±0.78mg/dL versus 4.22±0.51mg/dL, P=0.189, independent t-test).The salivary flow rate in patients with Sjogren's syndrome was significantly lower than that in controls (0.12±0.07 mL/minute versus 0.4±0.14mL/minute, P<0.0001, Mann Whitney U test).The cut-off point for discrimination of patients with Sjogren's syndrome was 0.165 mL/minute with 96% sensitivity and 90% specificity.The DMFS score was higher in the case group (78.08 versus 38.35, P<0.0001 based on independent t-test).The salivary flow rate was responsible for 34% of the changes in DMFS score while the calcium level was responsible for 0.2% of the changes. Conclusion:The salivary calcium level cannot serve as an indicator for the Sjogren's syndrome while 0.165 mL/min salivary flow rate is the cutoff point for accurate case detection.

Background and Aim: This study aimed to compare the cytotoxicity of AH Plus and DC Canal SE sealer after final setting.Materials and Methods: In this in vitro, experimental study, human gingival fibroblasts (HGFs) were cultured in Dulbecco's modified Eagle's medium supplemented with 10% fetal bovine serum, 100 U/mL penicillin, and 100 µg/mL streptomycin, and incubated at 37°C and 5% CO2.Cells at a density of 5000 cells/well were seeded in a 96-well plate for the methyl thiazolyl tetrazolium (MTT) assay.The cells were incubated with AH Plus and DC Canal SE sealers.Specimens of freshly mixed sealers were fabricated with 4 mm height and 10 mm diameter, and incubated at 37°C for 24 hours for setting.Each specimen was incubated with 10 mL of diluted culture medium at 37°C and 5% CO2 for 24 hours.Finally, the solution was filtered using a 0.22-µm filter.Different dilutions (1, 1/2, 1/4, 1/8) were prepared, and cell viability was assessed at 24 and 72 hours by measuring the optical density of the solutions spectrophotometrically.Data were analyzed by ANOVA and Tukey's test.Results: Cell viability in presence of all concentrations of AH Plus and DC Canal SE was significantly lower at 72 hours compared with 24 hours (P<0.001).Cell viability in presence of AH Plus was significantly higher compared with DC Canal SE at all concentrations and time points.Conclusion: Cell viability was higher in presence of AH Plus compared with DC Canal SE sealer in all concentrations and time points.

儿童糖尿病失控及近期失明情况下成功管理鼻脑毛霉菌病：一例报告

Background and Aim: Nowadays, facial esthetics has become the main concern for many people.Gummy smile (GS) is a common complaint that affects the esthetics and psychological status of patients.The aim of this study was to review GS treatment options.Materials and Methods: An electronic search was conducted in three databases of PubMed, Wiley and Cochrane Library from January 2015 up to August 2021.According to the eligibility criteria, a total of 41 relevant papers were retrieved and reviewed.Results: Based on the available data, several techniques have been reported for GS treatment, such as lip repositioning, crown lengthening, orthognathic surgery, laser application, botulinum toxin (BT) injection, hyaluronic acid injection, and micro autologous fat transplantation (MAFT).Combination of two or three of these techniques may yield a better result.Conclusion: A wide variety of procedures are available based on the cause of GS.The new, less invasive, faster and safer alternative techniques were shown to be feasible with a long-lasting result and minimal postoperative sequelae.Such treatment options for various types of GS can lead to significant improvement in smile esthetics with high patient satisfaction.

Background and Aim: Considering the significance of oral hygiene maintenance during orthodontic treatment, this study aimed to assess the oral hygiene awareness of patients undergoing orthodontic treatment and evaluate how compliant the patients are to the oral hygiene instructions given to them by dentists.Materials and Methods: Two researcher-designed questionnaires were used for assessment of oral hygiene awareness.One was given to patients between 12-40 years undergoing orthodontic treatment to assess the oral hygiene awareness of patients, and the other questionnaire was given to general dentists and orthodontists to assess their awareness regarding the provision of patients with ideal oral hygiene instructions.Each questionnaire consisted of 15 questions, and the study was conducted from June 2021 to August 2021.The questionnaires were administered online to 200 orthodontic patients and 200 dentists of various colleges in Tamil Nadu.Both male and female patients were included.The validity of the questionnaires was confirmed by a content validity index of 0.73.Results: Averagely 40% of patients did not follow the instructions given by their dentists and hence were unaware of oral hygiene maintenance measures during orthodontic treatment.The majority of patients (77%) were compliant to regular monthly appointments.Also, females were more concerned and more aware of how to maintain a good oral health, as compared to males. Conclusion:In the present study, most patients were compliant to their regular appointment schedules.A considerable number of patients did not follow the instructions given by their dentists and hence remained unaware of oral hygiene maintenance measures during orthodontic treatment.
