Improvement of periodontal parameters following intensive diabetes care and supragingival dental prophylaxis in patients with type 2 diabetes: A prospective cohort study. J Clin Periodontol 2024; 51:733-741. [PMID: 38449337 DOI: 10.1111/jcpe.13958] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2023] [Revised: 01/21/2024] [Accepted: 01/22/2024] [Indexed: 03/08/2024]
Abstract
AIM This study aimed to investigate the effects of diabetes care on periodontal inflammation. MATERIALS AND METHODS This prospective cohort study included 51 Japanese patients with type 2 diabetes who underwent intensive diabetes care including educational hospitalization and regular outpatient treatment for 6 months. Dental prophylaxis without subgingival scaling was provided three times during the observational period. Associations between changes in periodontal parameters and glycaemic control levels were evaluated using multiple regression analysis. RESULTS Overall, 33 participants (mean age: 58.7 ± 12.9) were followed up for 6 months. At baseline examination, 82% were diagnosed with Stage III or IV periodontitis. Haemoglobin A1c (HbA1c) level changed from 9.6 ± 1.8% at baseline to 7.4 ± 1.3% at 6 months. The ratio of probing pocket depth (PPD) ≥4 mm, bleeding on probing (BOP), full-mouth plaque control record (PCR), periodontal epithelial surface area (PESA) and periodontal inflamed surface area (PISA) also significantly improved. The reduction in PPD and PESA was significantly associated with changes in both HbA1c and fasting plasma glucose (FPG) levels, and the reduction in PISA was significantly associated with an improvement in FPG after adjusting for smoking, change in body mass index and full-mouth PCR. CONCLUSIONS This is the first study to report a significant improvement in PPD and BOP after intensive diabetes care and dental prophylaxis without subgingival scaling. CLINICAL TRIAL REGISTRATION NUMBER UMIN000040218.

Association of periodontal pocket area with type 2 diabetes and obesity: a cross-sectional study. BMJ Open Diabetes Res Care 2021; 9:e002139.

Abstract
INTRODUCTION The aim was to investigate the relationship of full-mouth inflammatory parameters of periodontal disease with diabetes and obesity. RESEARCH DESIGN AND METHODS This cross-sectional study conducted diabetes-related examinations and calculated periodontal inflamed and epithelial surface area (PISA and PESA) of 71 Japanese patients with type 2 diabetes. Multiple linear regression analyses were performed to evaluate associations between PISA or PESA and diabetes and obesity parameters. RESULTS Median value of body mass index (BMI), hemoglobin A1c (HbA1c) level, fasting plasma glucose (FPG) level, and visceral fat area (VFA) were 25.7 kg/m2, 9.1%, 151 mg/L, and 93.3 cm2, respectively. PISA and PESA were significantly associated with HbA1c after adjusting for age, sex, BMI, smoking status, and full-mouth plaque control level (PISA: coefficient=38.1, 95% CI 8.85 to 67.29, p=0.001; PESA: coefficient=66.89, 95% CI 21.44 to 112.34, p=0.005). PISA was also significantly associated with the highest FPG tertile (>175 mg/dL) after adjusting for confounders (coefficient=167.0, 95% CI 48.60 to 285.4, p=0.006). PISA and PESA were not significantly associated with BMI or VFA. CONCLUSION PISA was associated with FPG and HbA1c, but not with obesity parameters, independent from confounders such as full-mouth plaque control level in patients with type 2 diabetes.

Kataoka H, Miyatake N, Kitayama N, Murao S, Tanaka S. An exploratory study of relationship between lower-limb muscle mass and diabetic polyneuropathy in patients with type 2 diabetes. J Diabetes Metab Disord 2020; 19:281-287. [PMID: 32550177 DOI: 10.1007/s40200-020-00505-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/30/2019] [Accepted: 02/04/2020] [Indexed: 12/25/2022]
Abstract
Purpose This exploratory study compared the lower-limb muscle mass (thigh muscle mass [TMM] and lower-leg muscle mass [LLMM]) in type 2 diabetic patients with and without diabetic polyneuropathy (DPN). Methods A total of 130 patients with type 2 diabetes, hospitalized for glycemic control, were enrolled in this cross-sectional study. TMM and LLMM were measured using the bioelectrical impedance method. The muscle mass value was normalized by the bodyweight, and the total muscle mass was calculated by combining the muscle mass on the left and right (%TMM and %LLMM). DPN was evaluated according to the Japanese criteria. Anthropometric parameters, blood pressure, laboratory data, exercise habits, medication, related index of diabetes, and diabetic complications were analyzed. Results Sixty patients, comprising of 32 males (47.8%) and 28 females (44.4%) with type 2 diabetes (46.2%), had DPN. The %TTM and %LLMM were significantly lower in type 2 diabetic patients with DPN than in those without DPN. Multiple regression analysis identified DPN, age, and hemoglobin A1c (HbA1c) as the determinants of %TMM, and DPN and HbA1c were identified as the determinants of %LLMM in type 2 diabetic patients. Discussion The %TMM and %LLMM were significantly decreased in type 2 diabetic patients with DPN. DPN was found to be the strongest determinant of %TMM and %LLMM. Preventing and improving DPN, through active physical therapy, may increase the muscle mass of the lower limbs.
