RESUMO
Objectives: This study aimed to establish lactate dehydrogenase [LDH] and Beta-glucuronidase as salivary biomarkers of periodontitis among smokers and non-smokers
Methods: This cross-sectional case-control study was conducted at the Aligarh Muslim University, Aligarh, India, between January and June 2017. A total of 200 participants were divided into four groups based on their periodontal and smoking statuses. Unstimulated mixed saliva samples were collected to estimate LDH and Beta-glucuronidase levels. In addition, total protein was estimated using Lowry's method
Results: There was a significant increase in enzyme activity in the periodontitis groups compared to the nonperiodontitis groups [P <0.001]. However, significantly lower enzyme activity was observed among smokers, irrespective of periodontal status [P <0.001]. Nevertheless, a receiver operating characteristic curve analysis indicated the diagnostic potential of both enzymes to be fair-to-excellent
Conclusion: Although smoking was found to significantly alter enzyme activity, LDH and â-glucuronidase were reliable salivary biomarkers of periodontitis among both smokers and nonsmokers
RESUMO
PURPOSE: Diabetes and periodontal disease are two common diseases with high prevalence rates. Recent evidence has shown a bidirectional relationship between diabetes and periodontitis. The aim of this study was to investigate the effects of nonsurgical periodontal therapy on glycemic control in type 2 diabetes mellitus patients. METHODS: Sixty subjects aged 35-45 years with blood sugar controlled by oral hypoglycaemic agents were randomly divided equally among 3 groups: group A (scaling, mouthwash, and brushing), group B (mouthwash and brushing), and group C (brushing only). Glycated haemoglobin (HbA1c), fasting blood sugar (FBS), probing pocket depth (PPD), gingival index (GI), plaque index (PI), and the relevant drug history were recorded at baseline and after 3 months of intervention. Comparison of the mean difference among the variables was performed by parametric and nonparametric tests, which were further evaluated using multiple regression analysis. RESULTS: The mean differences between the PPD, FBS, HbA1c, GI, and PI in groups A and B were found to be statistically significant (P<0.001). Multiple regression analysis in group A showed that out of all the independent variables, GI and frequency of drug administration independently (b=0.3761 and b=0.598) showed a significantly greater impact on HbA1c (R2=0.832, P<0.05). CONCLUSIONS: Nonsurgical periodontal therapy can effectively decrease HbA1c levels in type 2 diabetes mellitus patients on medication.
