BackgroundDiabetes mellitus is one of the systemic disease which is show important oral manifestation and influence oral health. This study describes how diabetes mellitus affects oral health and oral health-related quality of life. The aim of this study was to evaluate the oral health and oral health-related quality of life of diabetic patients and compare the discriminative capability of Persian versions of two GOHAI and OHIP-14 questionnaires in these patients.MethodsA total of 350 patients with Type II diabetes mellitus, referring to the Diabetes Clinic, were selected and data were collected by GOHAI and OHIP-14 questionnaires completed by patients and clinical examinations. Oral health parameters (CAL,BI,GI,PLI,DMFT and xerostomia) were measured, also concurrent validity and conformity of two questionnaires were assessed. In order to test Discriminant analysis capabilities of two questionnaires, ADD and SC scores of questionnaires were divided into two parts and a logistic regression model was designed, which included subjective and objective variables.ResultsMean patients age was 55 years (with 75.4% female patients). The results showed that some oral conditions such as xerostomia, clinical attachment loss, number of missing teeth and plaque index were correlated to diabetes control level (HbA1c) and type of anti-diabetic medication. ADD and SC scores of two questionnaires were at high level. However, the effect of oral problems on decreasing OHRQoL was evident. Both questionnaires had acceptable concurrent validity and conformity. Moreover, there was a strong correlation between GOHAI and OHIP-14. OHIP-14 questionnaire had a higher discriminant analysis capability compared to GOHAI and better diagnosed patients who needed dental treatments: patients with higher GI, xerostomia and those wearing partial dentures.ConclusionDiabetic patients did not show acceptable oral health status and in some extent, oral problems affected oral health-related quality of life. Psychotherapy courses and solving oral problems of the patients can improve OHRQoL. OHIP-14 had higher discriminant analysis capability and was more effective in diagnosing oral problems.

Background and the purpose of the StudyComplementary medicine received high attention during last decades. We aimed to assess the efficacy of Green tea mouthwash on plaque-induced gingivitis as the most common form of periodontal disease.Methods and materialsWe designed a single blinded placebo controlled clinical trial. High school female students with chronic generalized plaque-induced gingivitis were distributed to receive either 5 ml of Green tea 5% two times/day or normal saline with the same dosage. Gingival index (Sillness & Loe), plaque index (Sillness & Loe) and bleeding index (Barnett) were recorded at baseline and five consecutive weeks. Comparisons were made by a general linear model, repeated measure ANOVA and a Bonferroni test applied for multiple comparisons.ResultsTwenty five students were recruited in each arm of the study. A significant improvement was observed in all periodontal indices during the study (P < 0.001). Two groups were contrasted by changing patterns of alteration of indices (P < 0.05). Although total amount of improvement was higher in mouthwash group, the differences did not reach a statistically significant level (P > 0.05, observed power for GI: 0.09, PI: 0.11 and BI: 0.07).ConclusionGreen tea mouthwash may be a safe and feasible adjunct treatment for inflammatory periodontal diseases. A future larger scale study is warranted for better evaluating the effect of green tea.

The findings high light the need of comprehensive oral examinations including periodontal therapy, restorative treatment, preventive dental treatment and follow-up care in the hemodialysis patients.

Background Mesenchymal stem cells (MSCs) derived from periodontal ligament (PDL) and gingiva can be used for the development of cell‐based regenerative approaches in dentistry and medicine. The purpose of this investigation was to establish a method for isolation of human stem cells from the PDL and gingiva, multilineage differentiation of those cells, and comparison of periodontal ligament mesenchymal stem cells (PDLMSCs) and gingival mesenchymal stem cells (GMSCs). Methods PDL and gingival tissues of third molar teeth were digested enzymatically and the proliferative potential of human PDLMSCs and GMSCs was compared by MTT assay. The expression of cell surface epitopes was analyzed by flow cytometry. To investigate the multilineage differentiation capacity of these stem cells, osteogenic and adipogenic differentiation was achieved. The specific staining of nodules was performed to evaluate differentiation, whereas the expression of alkalin phosphatase (ALP) and collagen A I (COL I) genes was analyzed by quantitative real‐time polymerase chain reaction. Results The outgrown cells derived from PDL and gingival tissues were similar, fibroblast‐like, and spindle‐shaped. Further, the proliferation potential of GMSCs was greater than PDLMSCs. Both types of stem cells expressed MSC precursor markers, including CD73, CD90, and CD105, whereas they were negative for hematopoietic markers, including CD34 and CD45. PDLMSCs demonstrated more osteogenic potential compared to GMSCs with strong mineral noduls, and significantly greater expression of up‐regulated bone‐related markers ALP and COL I. Conclusion MSCs derived from PDL and gingiva demonstrated multipotent characteristics, suggesting new therapeutic approaches in tissue engineering and PDLMSCs are more appropriate candidates for this purpose.

Aim: Scaling and root planning (SRP) is a major component of periodontal therapy which is often accompanied by painful experiences for the patient. The objective of the present study is to evaluate the pain control of two available types of ibuprofen, soft gelatin capsules and tablets, following SRP in patients with chronic periodontitis. Methodology: 75 patients with chronic periodontitis, undergoing routine periodontal SRP were selected. Following probing the amount of pain perceived was recorded as the baseline pain using visual analog scale (VAS). Further, they received either 800 mg ibuprofen tablet, 800 mg ibuprofen capsule or placebo and the pain level was measured thirty minutes thereafter. Participants underwent SRP procedure and the pain levels were recorded immediately and then at 30 and 60 minutes after SRP. Results: The mean VAS pain scores assessed immediately, thirty minutes and an hour after SRP for both ibuprofen and ibuprofen capsule groups were lower than placebo. Significant difference in the pain parameter only immediately after SRP between three groups were observed (p=0.012).The mean VAS pain score difference after thirty minutes and an hour upon SRP with baseline was insignificant in all study groups (p≤0.0001). However, the mean VAS pain score measured an hour after SRP showed significant difference between both NSAID groups and placebo group (p=0.012) Conclusions: Soft gelatin ibuprofen capsules are well suitable for pain management during SRP procedure in patients with chronic periodontitis due to reported rapid onset of action and less gasterointestinal intolerance.
