Oral Candida carriage and species prevalence in denture stomatitis patients with and without diabetes.

The objective of this study was to assess the oral Candida carriage and species prevalence in denture stomatitis (DS) patients with and without diabetes mellitus (DM). To address the focused question "In patients receiving dentures, how does having diabetes compared to no diabetes influences the carriage and species prevalence of oral Candida?" Indexed databases were explored without time or language restrictions up to and including February 2017. Nine studies were included. In these studies, the number of diabetics ranged between 14 patients and 405 individuals with mean ages ranging between 33 years and 66.4 years. In five studies, the percentage of hyperglycemic patients in the diabetic group ranged from 14.3% to 100%. In one study, all diabetic patients were normoglycemic. Seven studies reported Candida-associated DS to be significantly higher among diabetics than non-diabetics. Candida albicans was the most prevalent species isolated among diabetics and non-diabetics with DS. Denture-wearers with DM are more susceptible to Candida-associated DS as compared to non-diabetics.

Comparison of clinical and radiographic status around immediately loaded versus conventional loaded implants placed in patients with type 2 diabetes: 12- and 24-month follow-up results.

There are no studies that have compared the clinical and radiographic status around immediately loaded (IL) and conventional loaded (CL) implants placed in patients with type 2 diabetes mellitus (T2DM). The aim was to compare the clinical and radiographic status around IL and CL implants placed in T2DM patients. One hundred and eight diabetic patients [55 with IL implants (Group 1) and 53 with CL implants (Group 2)] were included in this cross-sectional study. All implants were placed in healed sites in the maxillary and mandibular premolar and molar regions and supported single restorations. All patients underwent full mouth mechanical debridement biannually. Haemoglobin A1c (HbA1c) levels, clinical [bleeding on probing (BOP) and probing depth (PD) ≥ 4 mm] and radiographic [crestal bone loss (CBL)] peri-implant parameters were measured for both groups at 12- and 24-month follow-up. Group comparisons were performed using the Mann-Whitney U-test (P < 0·05). The mean age and duration of T2DM in groups 1 and 2 were 50·6 ± 2·2 and 51·8 ± 1·7 years, and 9·2 ± 2·4 and 8·5 ± 0·4 years, respectively. At 12- and 24-month follow-up, the mean HbA1c levels in groups 1 and 2 were 5·4% (4·8-5·5%) and 5·1% (4·7-5·4%) and 5·1% (4·7-5·2%) and 4·9% (4·5-5·2%), respectively. At 12- and 24-month follow-up, there was no statistically significant difference in peri-implant BOP, PD and CBL in both groups. It was concluded that clinical and radiographic status is comparable around IL and CL implants placed in patients with T2DM. The contribution of careful case selection, oral hygiene maintenance and glycaemic control is emphasised.

Knowledge and attitudes of dentists toward shortened dental arch therapy in Saudi Arabia.

OBJECTIVE: The aim of this study was to assess and compare the knowledge and attitudes of dentists toward shortened dental arch (SDA) therapy in Saudi Arabia. MATERIALS AND METHODS: In this cross-sectional study, self-designed-structured questionnaires were distributed among specialists (SP), residents (RES), and general dental practitioners (GDP) in Saudi Arabia. The questionnaire enquired about dentists' opinion regarding function, esthetic, and comfort in patients with SDA. It also enquired about the risks associated with SDA treatment (tooth wear, temporomandibular dysfunction (TMD), and tooth migration). Participants also graded SDA decision-making factors for their significance. Frequency distribution and Chi-square test were performed to compare the responses. RESULTS: A total of 300 questionnaires were completed. 53.9% of SP applied SDA therapy in <10% of patients. However, 54.8% of RES and 46.6% of GDP never used SDA therapy. SDA was considered by dentists to provide a satisfactory or acceptable function (76.4%), esthetics (76.1%), and comfort (76.8%). There was a significant difference in opinions of SP, GDP, and RES, in relation to the effect of SDA on esthetics (P = 0.039), tooth-wear (P < 0.001), TMD (P < 0.001), and tooth migration (P = 0.002). CONCLUSION: The knowledge of SP and GDP with regards to SDA therapy was broadly in line with current standards. Less than 10% of patients had objections towards SDA therapy. SDA therapy was clinically applied in fewer than 10% of cases.

Self-perceived oral health and whole salivary immunoglobulin G levels in habitual gutka-chewers and nonchewers.

OBJECTIVE: To assess self-perceived oral health and whole salivary immunoglobulin G (IgG) levels among habitual gutka-chewers and nonchewers (controls). MATERIALS AND METHODS: Fifty gutka-chewers and fifty controls were included. Demographic data and self-perceived oral health status (pain in teeth, pain on chewing, bleeding gums (BG), bad breath, loose teeth and daily oral hygiene protocols) were collected using a questionnaire. Unstimulated whole saliva (UWS) was collected and unstimulated whole salivary flow rate (UWSFR) was determined. Whole salivary IgG levels were determined using standard techniques. Odds ratios were calculated for oral symptoms and group differences in protein levels were compared using one-way analysis of variance (α± <5%). RESULTS: BG was more often reported by gutka-chewers than controls (P < 0.05). There was no significant difference in UWSFR and self-perceived pain in teeth, pain on chewing, bad breath and loose teeth among gutka-chewers and controls. IgG levels were significantly higher among gutka-chewers than controls (P < 0.01). Among gutka-chewers, whole salivary IgG levels were comparable individuals with and without self-perceived oral symptoms. Among controls, IgG levels in UWS were significantly higher among individuals who had BG than those who did not (P < 0.05). CONCLUSIONS: Self-perceived oral health is worse and whole salivary IgG levels are higher in gutka-chewers compared to controls.

Comparison of periodontal inflammatory conditions among habitual gutka chewers and betel quid chewers.

OBJECTIVE: The aim was to compare the periodontal inflammatory conditions among habitual gutka chewers and betel quid (BQ) chewers. MATERIAL AND METHODS: Forty-five gutka chewers, 45 BQ chewers and 50 non-chewers (controls) were included. Demographic data regarding age, gender, duration, and frequency of gutka- and BQ-chewing habits and gingival bleeding were collected using a questionnaire. Clinical periodontal parameters [plaque index (PI), bleeding on probing (BOP), probing depth (PD) and clinical attachment loss (AL)] were recorded. Marginal bone loss (MBL) was measured on digital panoramic radiographs. Group differences in periodontal inflammatory parameters were tested using univariate and multivariable analyses (α < 5%). RESULTS: Periodontal inflammatory parameters [PI, BOP, PD (4-6 and >6 mm), clinical AL and MBL] were significantly high in gutka and BQ chewers than controls. There was no significant difference in periodontal inflammatory parameters among gutka and BQ chewers. The odds for gingival bleeding were six times and 13 times higher in gutka and BQ chewers, respectively, compared to controls. Comparison of gutka and BQ chewers did not significantly increase the odds of gingival bleeding. CONCLUSION: Periodontal inflammatory conditions were comparable among habitual gutka and BQ chewers; which suggests that gutka chewers and BQ chewers are equally susceptible to periodontal disease.

Association between periodontal disease and polycystic ovary syndrome: a systematic review.

The purpose of the present study was to review systematically the association between periodontal diseases (PDs) and polycystic ovary syndrome (PCOS). To address the focused question, 'Is there a relationship between PD and PCOS?' indexed databases were searched up to October 2016 without time or language restrictions using different combinations of the following key words: PCOS, ovarian cysts, PD, periodontitis, gingival diseases and gingivitis. Letters to the Editor, commentaries, historic reviews, case-report, unpublished articles and animal/experimental studies were excluded. Seven case-control studies were included. The number of study participants ranged between 52 and 196 females aged between 15 and 45 years. In three and three studies, proinflammatory cytokines were assessed in gingival crevicular fluid and saliva samples, respectively. In one study, salivary microbes were investigated. All studies reported that a positive association exists between PD and PCOS. In conclusion, there is a positive association between PD and PCOS; however, further well-designed longitudinal controlled clinical trials are needed in this regard. It is recommended that physicians should refer patients with PCOS to oral health-care providers for comprehensive oral evaluation and treatment.

Influence of smoking on clinical parameters and gingival crevicular fluid volume in patients with chronic periodontitis.

BACKGROUND: Tobacco smoking is regarded as one of the most significant risk factors for the development and progression of periodontal disease. In particular, studies have shown an alteration in Gingival Crevicular Fluid (GCF) volume and its components in smokers. OBJECTIVE: The purpose of this study was to compare the GCF volume in smoking and non-smoking Saudi subjects with chronic periodontitis. METHODS: In this study, 30 smoking patients and 30 non-smoking patients with chronic periodontitis were enrolled. Periodontal Probing Depth (PPD), Clinical Attachment Level (CAL), Plaque Index (PI), and Bleeding on Probing (BOP) were measured to assess the pattern of periodontal destruction for each patient at six sites in selected teeth. Gingival inflammation was registered at six sites, where Gingival Crevicular Fluid (GCF) was also collected. The GCF volume was measured with a Periotron 8000®. Comparisons were made between smoking and non-smoking groups with periodontitis. RESULTS: Smokers demonstrated significantly deeper periodontal pockets (4.64±0.30 mm) than non-smokers (4.24±0.38 mm). Smoking subjects also presented significantly greater attachment loss (3.08±0.28 mm) than non-smoking subjects (2.74±0.42 mm), whereas the GCF volume was found to be significantly lower in smokers (0.25±0.04 µl) than in non-smokers (0.31±0.05 µl) (P<0.01). Among smoking subjects, lingual sites showed reduced GCF levels compared to facial sites (0.22±0.03 µl vs. 0.25±0.03 µl). CONCLUSION: Smoking appears to have considerable adverse effects on the inflammatory process, thereby promoting the progression of periodontal disease in smokers. CLINICAL SIGNIFICANCE: The adverse effect of smoking on the initiation and progression of periodontal disease is highlighted in this study. In particular, estimation of the GCF volume may serve as an indicator to assess the severity as well as the prognosis of periodontitis in smokers.
