Comparison of self-perceived oral health, periodontal inflammatory conditions and socioeconomic status in individuals with and without prediabetes

Role of PDT as an adjunct to SRP on whole salivary RANKL and OPG ratio in type-2 diabetic and normoglycemic individuals with chronic periodontitis

OBJECTIVE

The aim was to assess the effect of scaling and root planing (SRP) with and without adjunct photodynamic therapy (PDT) on the levels of osteoprotegerin (OPG) receptor activator of NF-kappa B ligand (RANKL) in the unstimulated whole saliva (UWS) of type-2 diabetic and normoglycemic individuals with chronic periodontitis (CP).

METHODS

Type-2 diabetic and normoglycemic subjects with CP (Groups 1 and 2, respectively) were divided into test- (SRP + PDT) and control (SRP only) groups. Patient demographics were recorded; and periodontal parameters (marginal bone loss [MBL], probing depth [P.D], plaque index [PI], gingival index [GI], and clinical attachment loss [CAL]) were assessed at baseline and at 3-months-follow-up. Rate of flow of unstimulated whole saliva and levels of RANKL and osteoprotegerin were measured at both time intervals. P < 0.05 was considered statistically significant.

RESULTS

Eighty-four persons with CP (42 with and 42 without type-2 DM) were included. At baseline, clinicoradiographic parameters were comparable in all groups. At 3-months of follow-up, there was no significant difference in the clinicoradiographic parameters in all groups. At 3-months of follow-up, there was no significant reduction in whole salivary RANKL and osteoprotegerin levels among individuals in the test and control groups among CP patients with and without CP.

CONCLUSION

The whole salivary RANKL/OPG ratio remains high in patients with poorly-controlled type-2 DM after SRP with or without adjunct PDT.

Betel Quid Health Risks of Insulin Resistance Diseases in Poor Young South Asian Native and Immigrant Populations

Betel quid, traditionally prepared with areca nut, betel leaf, and slaked lime, has been consumed for thousands of years, mainly in the form of chewing. Originally used for cultural, medicinal, and ceremonial purposes mainly in South Asian countries, its use has recently spread across the globe due to its psychoactive, euphoric, and aphrodisiac properties. Now it is widely used as a social lubricant and source of financial profit. Unfortunately, the profit motive has led to high rates of habitual consumption with eventual conversion to addiction among young girls and boys. Moreover, the worrisome practice of including tobacco in quid preparations has grown, particularly among pregnant women. Major health concerns include increased rates of malignancy, oral pathology, and cardiovascular, hepatic, fertility, metabolic, and neuropsychiatric disorders. Metabolic disorders and insulin resistance disease states such as type 2 diabetes, obesity, and metabolic syndrome contribute to cognitive decline and neurodegeneration. Mechanistically, the constituents of areca nut/betel quid are metabolized to N-nitroso compounds, i.e., nitrosamines, which are carcinogenic at high doses and cause insulin resistance following chronic low-level exposures. From an epidemiological perspective, the rising tide of insulin resistance diseases including obesity, diabetes, and dementias that now disproportionately burden poor countries has been propagated by rapid commercialization and enhanced access to betel quid. Public health measures are needed to impose socially and ethically responsible barriers to yet another cause of global health disparity.

Antimicrobial efficacy of 0.8% Hyaluronic Acid and 0.2% Chlorhexidine against Porphyromonas gingivalis strains: An in-vitro study

Objective:

The aim of the present in-vitro study was to assess antimicrobial efficacy of 0.8% hyaluronic acid (HA) and 0.2% Chlorhexidine gluconate (CHX) against Porphyromonas gingivalis (P. gingivalis).

Methods:

The study was performed between December 2018 and March 2019 at the College of Dentistry at the Princess Nourah Bint Abdulrahman University, Riyadh, Saudi Arabia. The P. gingivalis biofilms were formed and grown for 72 hours at 37°C under anaerobic conditions on glass slides coated with human saliva. The slides were individually positioned and exposed to 0.8% HA or 0.2% CHX. Therapeutically, the biofilms were divided into 3 groups as follows: (a) negative group; (b) 0.8% HA group and (c) 0.2% CHX group. P-values less than 0.05 were considered statistically significant.

Results:

In the 0.8% HA group, P. gingivalis CFUs/ml were significantly higher at baseline than at 24- (P<0.05), 48 (P<0.05) and 72 hours (P<0.05) intervals. In the 0.2% CHX group, P. gingivalis CFUs/ml were significantly higher at baseline than at 72 hours interval (P<0.05). In the CHX group, there was no difference in P. gingivalis CFUs/ml between baseline, 24- and 48-hours intervals. At 48- and 72-hours intervals, the P. gingivalis CFUs/ml were significantly higher in the 0.2% CHX group compared with the 0.8% HA group.

Conclusion:

In-vitro, 0.8% HA is more effective in reducing the P. gingivalis CFUs/ml compared with 0.2% CHX.

Comparing the Frequency of Some Oral Lesions in Prediabetic and Healthy Individuals: Is There Any Difference?

BACKGROUND

Diagnosis of prediabetic stage is very important for prevention of diabetes and complications. This stage may be associated with some oral lesions. Only a few studies are available on the oral status of prediabetic patients and incidence of oral lesions in this population. This study aimed to compare some oral complications between prediabetic and healthy control groups.

METHODS

The present two-group cross-sectional study was carried out on 302 prediabetic and non-diabetic (healthy) 20- to 60-year-old subjects. In this study, data on age, gender, educational level, medications use, smoking, and some other variables were extracted through history taking. In addition, orodental examination was carried out by an oral medicine specialist to diagnose oral lesions including candidiasis, lichen planus, periodontitis, gingivitis, xerostomia, delayed wound healing, geographic tongue, fissured tongue, and burning mouth sensation. Data entry and analysis was performed by SPSS version 22 software, and P value and odds ratio (OR) were calculated to show statistical relationship between variables.

RESULTS

The most common oral lesion in prediabetic subjects was periodontitis (27.2%), followed by gingivitis (14.7%) and xerostomia (11.3%). In the control group, gingivitis (20.5%) followed by periodontitis (11.3%) are common oral lesions. Candidiasis (P = 0.036), periodontitis (P < 0.001), and xerostomia (P < 0.001) in prediabetic subjects were higher than control group that is statistically significant. Regression analysis showed that in the prediabetic group, periodontitis [OR = 2.91, confidence interval (CI): 1.54-5.49] and xerostomia (OR = 18.51, CI = 2.42-141.45) were significantly more prevalent than healthy subjects.

CONCLUSION

Based on the results, glucose intolerance stage exhibited a significantly higher oral problems such as periodontitis and xerostomia than healthy euglycemic stage.

Oral Health in Women with a History of High Gestational Diabetes Risk

We studied oral health in 115 women with and without a history of gestational diabetes (GDM), expecting poorer oral health in the GDM group. Full-mouth examinations were performed 5 years postpartum and the number of teeth, total dental index (TDI) and decayed, missing, filled teeth (DMFT) index were calculated. Bleeding on probing (BOP), probing depth (PD), visible plaque index (VPI), and clinical attachment level (CAL) were recorded. The periodontal inflammatory burden index (PIBI) was calculated. Panoramic radiographs were taken and signs of infections recorded. Oral health habits, symptoms and participants' own opinion of oral health were recorded with questionnaires. At the time of examination, 45% of the women had a history of GDM in the index pregnancy. Mild periodontitis (62%) and bleeding on probing (46%) were common. VPI (13% and 17%, p = 0.009) and PIBI (13.1 and 17.5, p = 0.041) were lower among women with a history of GDM compared with those with no history of GDM. There was no difference between groups in DMFT scores. All women reported good subjective oral health. Thus, contrary to our hypothesis, women with a history of GDM showed better oral health parameters than women without a history of GDM.

Candida sp. Infections in Patients with Diabetes Mellitus

Candidiasis has increased substantially worldwide over recent decades and is a significant cause of morbidity and mortality, especially among critically ill patients. Diabetes mellitus (DM) is a metabolic disorder that predisposes individuals to fungal infections, including those related to Candida sp., due to a immunosuppressive effect on the patient. This review aims to discuss the latest studies regarding the occurrence of candidiasis on DM patients and the pathophysiology and etiology associated with these co-morbidities. A comprehensive review of the literature was undertaken. PubMed, Scopus, Elsevier’s ScienceDirect, and Springer’s SpringerLink databases were searched using well-defined search terms. Predefined inclusion and exclusion criteria were applied to classify relevant manuscripts. Results of the review show that DM patients have an increased susceptibility to Candida sp. infections which aggravates in the cases of uncontrolled hyperglycemia. The conclusion is that, for these patients, the hospitalization periods have increased and are commonly associated with the prolonged use of indwelling medical devices, which also increase the costs associated with disease management.

Impact of jaw location on clinical and radiological status of dental implants placed in cigarette-smokers and never-smokers: 5-year follow-up results

PURPOSE

The aim of this 60 months follow-up investigation was to investigate the impact of jaw location on clinical and radiological status of dental-implant therapy in cigarette-smokers and never-smokers.

MATERIALS AND METHODS

Twenty-nine self-reported cigarette-smokers and 27 nonsmokers were assessed. All implants were categorized into three regions with reference to their location in the maxilla or mandible: (a) Anterior zone: implants located in anterior teeth; (b) Middle zone: Implants located in the premolar region; and (c) posterior zone: implants located in the molar region. Peri-implant crestal bone loss (CBL), bleeding-on-probing (BOP) and probing-depth (PD) ≥ 4 mm and were assessed. Level of statistical significance was set at P < .05.

RESULTS

Mean age of cigarette-smokers (n = 29) and never-smokers (n = 27) was 44.5 years (39-51 years) and 43.6 years (35-49 years), respectively. The average duration of cigarette-smoking was 20.3 years (17-26 years). The mean periimplant PD (P < .05) and CBL (P < .05) were significantly higher in cigarette-smokers in contrast to never-smokers in all zones. No statistically significant differences in CBL, PD, and BOP were observed in the three zones of implant location among cigarette-smokers and never-smokers.

CONCLUSION

Smoking enhanced PD and CBL around dental implants and this relationship was independent of site of implant placement and jaw location.

Self-perceived oral symptoms and periodontal inflammatory conditions in habitual naswar dippers

Objectives:

To compare self-perceived oral symptoms and clinical (plaque index [PI], bleeding on probing [BOP], clinical attachment loss [CAL]) and radiographic (marginal bone loss [MBL]) periodontal parameters among naswar (NW) and non-naswar dippers (NNW).

Methods:

One hundred and forty-two individuals (72 patients consuming naswar and 70 controls) were included. All participants completed a baseline questionnaire that included information regarding demographic characteristics and self-perceived oral symptoms. Clinical periodontal parameters (PI, BOP, PD and CAL) were recorded. MBL was measured on digital panoramic radiographs.

Results:

Pain in teeth, pain on chewing, bleeding gums and burning sensation in the mouth was significantly worse among NW than NNW (p<0.01). Clinical periodontal parameters and MBL were significantly high in NW than NNW (p<0.001). There was statistically significant influence of daily use and mean duration of naswar consumption on the severity of PI, BOP, PD (4 to 6 and >6 mm) and MBL among NW group.

Conclusions:

Self-perceived oral symptoms and periodontal parameters were worse among naswar dippers. It is highly recommended that naswar dipping should be considered a potential threat that could have major effects on periodontal tissues.

Comparison of periodontal and peri-implant inflammatory parameters among patients with prediabetes, type 2 diabetes mellitus and non-diabetic controls

OBJECTIVE

The aim was to compare periodontal and periimplant inflammatory parameters (plaque index [PI], bleeding on probing [BOP], probing depth [PD] and marginal bone loss [MBL]) among patients with prediabetes, type-2 diabetes mellitus (T2DM) and non-diabetic controls.

MATERIALS AND METHODS

Forty-five patients with prediabetes (Group-1), 43 patients with T2DM (Group-2) and 42 controls (Group-3) were included. Demographic data was recorded using a questionnaire. Full mouth and periimplant clinical (PI, BOP and PD) were assessed and the radiographic MBL were measured on digital radiographs. In all groups, haemoglobin A1c (HbA1c) levels were also measured. p values less than .05 were considered statistically significant.

RESULTS

The mean HbA1c levels of participants in groups 1, 2 and 3 were 6.1%, 8.4% and 4.8%, respectively. The mean duration of prediabetes and T2DM among patients in groups 1 and 2 were 1.9 ± 0.3 and 3.1 ± 0.5 years, respectively. Periodontal and periimplant PI, BOP, PD and MBL were higher in groups 1 (p < .05) and 2 (p < .05) than group 3. There was no difference in these parameters in groups 1 and 2.

CONCLUSIONS

Periodontal and periimplant inflammatory parameters were worse among patients with prediabetes and T2DM compared with controls; however, these parameters were comparable among patients with prediabetes and T2DM.

Influence of implant location in patients with and without type 2 diabetes mellitus: 2-year follow-up

The aim of the present cross-sectional retrospective 2-year follow-up clinical study was to assess the influence of implant location on clinical and radiographic parameters around dental implants placed in patients with and without type 2 diabetes mellitus (T2DM). Twenty-seven patients with T2DM and 25 non-diabetic controls were included. Implants were classified into three zones according to their location: (1) anterior zone: implant/s replacing anterior teeth, (2) middle zone: implant/s replacing premolars, and (3) posterior zone: implant/s replacing molars. Peri-implant bleeding on probing (BOP), probing depth (PD), and crestal bone loss (CBL) were measured. P-values less than 0.05 were considered statistically significant. The mean age of patients with T2DM was 42.5 years and that of non-diabetic controls was 40.6 years. The mean fasting blood glucose levels of patients with and without T2DM were 74.5mg/dl (66-80mg/dl) and 82.5mg/dl (79-88.1mg/dl), respectively. The mean duration of T2DM was 4.3 years. There was no significant difference in BOP, PD, or CBL around implants placed in any of the zones in the jaws of patients with and without T2DM. There is no influence of implant location on clinical and radiographic parameters around dental implants placed in patients with and without T2DM.

Efficacy of scaling and root planning with and without adjunct Nd:YAG laser therapy on clinical periodontal parameters and gingival crevicular fluid interleukin 1-beta and tumor necrosis factor-alpha levels among patients with periodontal disease: A prospective randomized split-mouth clinical study

BACKGROUND AND AIM

Limited evidence exists regarding the role of scaling and root planning (SRP) with adjunct neodymium yttrium aluminum garnet (Nd:YAG) laser therapy in reducing periodontal parameters (plaque index [PI], bleeding on probing [BOP] and probing pocket depth [PPD]) and levels of proinflammatory cytokines in the gingival crevicular fluid (GCF) among patients with periodontal disease (PD). The aim was to assess the effect of SRP with and without adjunct Nd:YAG laser therapy on clinical periodontal parameters and GCF interleukin 1-beta (IL-1β) and tumor necrosis factor-alpha (TNF-α) levels among patients with PD.

METHODS

Demographic data was collected using a questionnaire. Mandibular right and left quadrants were randomly divided into test- (SRP+Nd:YAG laser) and control-sites (SRP alone). PI, BOP and PPD were assessed and GCF IL-1β and TNF-α levels were measured at baseline and at 3- and 6-month follow-up. Level of significance was set at P<0.05.

RESULTS

Twenty-eight male patients with PD were included. At 3- and 6-month follow-up, PI (P<0.01), BOP (P<0.01) and PPD (P<0.01) were significantly higher in the control-sites than test-sites. In the test-sites, PI, BOP and PPD and GCF IL-1β and TNF-α levels were comparable at 3- and 6-month follow-up. At 6-month follow-up, IL-1β (P<0.05) and TNF-α (P<0.05) levels were significantly higher in control-sites than test-sites at 3- and 6-month follow-up.

CONCLUSION

At 3- and 6-month follow-up, SRP+Nd:YAG therapy was more effective in reducing periodontal inflammatory parameters and GCF IL-1β and TNF-α levels compared with SRP alone.

Effect of scaling and root planing with and without adjunctive use of an essential-oil-based oral rinse in the treatment of periodontal inflammation in type-2 diabetic patients

AIM

The aim was to assess the effect of scaling and root planing (SRP) with and without adjunctive use of an essential-oil (EO)-based oral rinse in the treatment of periodontal inflammation in type-2 diabetic (T2D) patients.

METHODS

Sixty T2D patients were included. In Group 1 (n = 30), SRP was performed and patients were instructed to rinse twice daily with EO-based oral rinse for 30 days. In Group 2 (n = 30), SRP was performed and participants were instructed to rinse twice daily with water for 30 days. Periodontal parameters (plaque index (PI), bleeding on probing (BOP), and probing pocket depth (PPD) ≥ 4 mm) and hemoglobin A1c (HbA1c) levels were assessed at baseline and after 90 days.

RESULTS

In both groups, periodontal parameters were similar at baseline. After 90 days of follow-up, there was a significant reduction in the severity of periodontal parameters in patients in Group 1 compared with Group 2. After 90 days of follow-up, there was also a significant reduction in HbA1c among patients in Group 1 compared with Group 2.

CONCLUSIONS

Scaling and root planing with adjunct use of an EO-based oral rinse is more effective in the treatment of periodontal inflammation in T2D patients than SRP alone. This approach also helps reduce hyperglycemia in T2D patients as compared with when SRP is performed alone.

Cross-sectional associations of impaired glucose metabolism measures with bleeding on probing and periodontitis

AIM

This study assessed the associations of pre-diabetes and insulin resistance with bleeding on probing (BOP) and periodontitis among adults.

MATERIALS AND METHODS

We included 1191 Hispanic adults aged 40-65 years, free of diabetes, enrolled in San Juan Overweight Adults Longitudinal Study. Pre-diabetes was defined as impaired fasting glucose (IFG), impaired glucose tolerance (IGT), or impaired glycated haemoglobin. Impaired one-hour plasma glucose (1hPG) was defined as levels >155 mg/dl. Insulin resistance was defined using the study population-specific 75th percentile (HOMA-IR ≥ 3.13). High BOP was defined as percentage of teeth with bleeding ≥30%. Periodontitis was defined according to the CDC/AAP definition.

RESULTS

After multivariable adjustment for age, gender, education, smoking status, alcohol consumption, physical activity, obesity, HDL-C, and plaque index, pre-diabetes with and without 1hPG, IFG, impaired 1hPG, IGT, and HOMA-IR were significantly associated with high BOP; pre-diabetes, IFG, and impaired 1hPG were significantly associated with severe periodontitis. Most of these associations remained significant when the analyses were restricted to non-smokers.

CONCLUSIONS

This study suggests associations between pre-diabetes and insulin resistance with BOP and periodontitis. Given the high prevalence of impaired glucose metabolism and periodontitis, the assessment of the temporal sequence of these associations is of utmost importance.

Crestal Bone Loss under Delayed Loading of Full Thickness Versus Flapless Surgically Placed Dental Implants in Controlled Type 2 Diabetic Patients: A Parallel Group Randomized Clinical Trial

PURPOSE

To compare crestal bone loss around dental implants using a delayed loading protocol. Bone loss was compared in patients following conventional full thickness flap and flapless surgery in controlled type 2 diabetic patients.

MATERIALS AND METHODS

Eighty-eight type 2 diabetic patients satisfying predetermined inclusion and exclusion criteria were selected for this single center, parallel group study after obtaining institutional review board approval and informed consent. These patients were randomly divided into two groups. Group I consisted of patients undergoing full thickness flap surgery for implant placement, and group II consisted of patients undergoing flapless surgery for implant placement. The mean age, duration of diabetes, glycosylated hemoglobin levels, and male-to-female ratio in both groups were matched and compared statistically. Dental implants were placed followed by delayed loading (4 months) in both groups. Crestal bone loss was assessed with intraoral periapical radiographs with the help of computer software (DBSWIN viewer). Actual implant length acted as the radiographic index, and implant-abutment junctions were used as a reference point for all measurements. Mesial and distal bone levels at baseline, 6, and 12 months post implant placement of the two groups were determined. Mesial and distal crestal bone loss from baseline to 6 and 12 months were calculated and compared with Tukey test using SPSS v15.0 statistical analysis software.

RESULTS

Tukey test revealed similar (not statistically different) mean mesial crestal bone loss between the two groups after 6 months (0.47 ± 0.08 mm vs. 0.36 ± 0.13 mm, p = 0.576) and after 12 months (1.56 ± 0.25 mm vs. 1.50 ± 0.22 mm, p = 0.891). The mean distal bone loss resulting between the two groups was not statistically different at 6 months (0.44 ± 0.08 mm vs. 0.35 ± 0.12 mm, p = 0.687) and at 12 months (1.57 ± 0.23 mm vs. 1.61 ± 0.22 mm, p = 0.947).

CONCLUSIONS

The results of this clinical randomized control trial indicated that in controlled type 2 diabetic patients, levels of crestal bone loss around dental implants placed following conventional full thickness flap surgery was comparable to crestal bone loss around dental implants placed with the flapless surgical technique. More clinical studies are required regarding controlled type 2 diabetics with larger sample sizes, for long time periods to obtain more predictable results.

Effect of Nd:YAG laser-assisted non-surgical periodontal therapy on clinical periodontal and serum biomarkers in patients with and without coronary artery disease: A short-term pilot study

BACKGROUND/OBJECTIVE

We hypothesized that nonsurgical-periodontal-therapy (NSPT) with adjunct Nd:YAG laser therapy is more effective in reducing periodontal inflammatory parameters (plaque index [PI], bleeding-on-probing [BOP], and probing-pocket-depth [PPD]) and serum interleukin-1beta (IL-1β) and matrix metalloproteinase-9 (MMP-9) levels in patients with and without coronary artery disease (CAD) than NSPT alone. The aim of this short-term pilot study was to assess the effect of NSPT + Nd:YAG laser therapy on periodontal parameters and serum IL-1β and MMP-9 levels in patients with and without CAD.

STUDY DESIGN

A prospective randomized clinical study was conducted on 87 patients who were divided into two groups: Group-1: 44 patients with CAD and periodontal disease (PD) and Group-2: 43 patients with PD alone. Treatment-wise, these individuals were randomly divided into two subgroups: (i) NSPT alone and (ii) NSPT + Nd:YAG laser therapy. Demographic information was collected using a self-completed questionnaire. Periodontal parameters (PI, BOP, and PPD) and serum IL-1β and MMP-9 levels were measured at baseline and after 3 months of treatment. P-values <0.05 were considered statistically significant.

RESULTS

At 3 months follow-up, PI (P < 0.01), BOP (P < 0.01), PPD ≥ 4 mm (P < 0.01), and serum IL-1β (P < 0.01) and MMP-9 (P < 0.01) levels were significantly higher in patients treated with NSPT alone than those treated with NSPT + Nd:YAG laser therapy. Among patients that underwent NSPT + laser therapy in both groups, periodontal parameters and serum IL-1β, and MMP-9 levels were comparable at 3-months follow-up.

CONCLUSION

NSPT + Nd:YAG laser therapy may be more effective in reducing periodontal inflammation and serum IL-1β and MMP-9 levels in patients with and without CAD than NSPT alone. Lasers Surg. Med. 48:929-935, 2016. © 2016 Wiley Periodicals, Inc.

Short-term effects of scaling and root planing with or without adjunctive use of an essential-oil-based mouthwash in the treatment of periodontal inflammation in smokers

OBJECTIVE

The aim of the present short-term follow-up study was to assess the effects of scaling and root planing (SRP) with or without adjunctive use of an essential-oil-based mouthwash in the treatment of periodontal inflammation in smokers.

METHODS

In total, 120 individuals were divided into 2 groups. In Group-1, 60 smokers with periodontal inflammation received SRP alone; and in Group-2, 60 smokers with periodontal inflammation received adjunct essential-oil mouthwash therapy. Periodontal parameters (plaque index [PI], bleeding-on-probing [BOP], and probing pocket depth [PD] ≥ 4 mm) were assessed at baseline and after 90 days of treatment.

RESULTS

There was no significant difference in periodontal parameters (PI, BOP, and PD ≥ 4 mm) among participants in Group-1 and -2. Participants in both groups showed significant reductions in PI (P < 0.01), BOP (P < 0.01), and PD ≥ 4 mm (P < 0.01) at follow-up compared to baseline. At 90 days of follow-up, PI (P < 0.05), BOP (P < 0.05), and PD ≥ 4 mm (P < 0.05) were significantly higher in Group-1 compared to Group-2.

CONCLUSIONS

SRP with adjunct essential-oil mouthwash therapy is more effective in the treatment of periodontal inflammation in smokers as compared to when SRP is performed alone.

The Association Between Pre-Diabetes With Body Mass Index and Marital Status in an Iranian Urban Population

Pre-diabetes increased the development of diabetes mellitus (type 2). The aim of study was to determine the association of body weight, education and marital status with pre-diabetes in an Iranian urban population.A sample of 788 subjects (360 men and 428 women) between the ages 30-85 years participated in our study and anthropometric measurements, educational level and fasting blood sugar of participants were recorded. The t and Chi square tests were used for continuous and categorical variables. The association of age, BMI categories, educational level and marital status to pre-diabetes was assessed by estimating the odds ratio. A p-value ≤ 0.05 were considered significant. The analysis was done using SPSS version 11.5. Our study showed that pre-diabetic subjects were older and low educated than normoglycemic subjects. Mean BMI and educational level were associated to pre-diabetes only in women. The odds of being pre-diabetes also were higher in obese women than in normal BMI women. No relationship was found between education and marital status with pre-diabetes in both men and women. Based on our finding, it is possible that advancing age and obesity has increased in pre-diabetes. This highlights the importance of population based survey to monitor blood glucose for effective prevention and control.

Comparison of an essential-oil-based oral rinse and chlorhexidine as adjuncts to scaling and root planing in the treatment of periodontal inflammation

OBJECTIVE

The aim of the present short-term follow-up study was to compare the effects of an essential oil (EO)-based oral rinse and chlorhexidine as adjuncts to scaling and root planing (SRP) in the treatment of periodontal inflammation.

METHODS

In Group-1, SRP was performed and participants were instructed to rinse with EO-based oral rinse; in Group-2, SRP was performed and participants were instructed to rinse with chlorhexidine; and in Group-3, SRP was performed and participants were instructed to rinse with water. Periodontal parameters (plaque index [PI], bleeding-on-probing [BOP], and probing pocket depth [PPD] ≥ 4 mm) were assessed at baseline and after 7 and 30 days.

RESULTS

In all groups, periodontal parameters (PI, BOP, and PPD ≥ 4 mm) were comparable at baseline. In Groups-1 and -2, there was a significant reduction in PI (P < 0.01), BOP (P < 0.01), and PD ≥ 4 mm after 7 days and 30 days of follow-up than baseline. In Group-3, there was a significant reduction in PI (P < 0.01) and BOP (P < 0.01) after 7 days of follow-up compared to baseline. There was no difference in periodontal parameters after 7 days and 30 days of follow-up in Groups-1 and -2.

CONCLUSION

EO-based oral rinses and chlorhexidine digluconate (CHX) are acceptable adjuncts to SRP in the treatment of periodontal inflammation.

Impact of scaling and root planing on clinical periodontal status and glycemic levels in prediabetic patients

OBJECTIVE

The aim was to assess the effect of scaling and root planing (SRP) on clinical periodontal parameters and glycemic levels in prediabetic patients.

METHODS

Fifty prediabetic patients with periodontal disease were included. Demographic data (age, gender, education status, duration of prediabetes, type of treatment adopted for prediabetes management, and oral hygiene maintenance protocols) were recorded using a questionnaire. Patients were randomly divided into two groups (25 patients/group). In Group 1, SRP alone was performed, in Group 2, SRP + oral doxycycline (100 mg) administration. In both groups, fasting blood glucose (FBG) levels and periodontal parameters (plaque index [PI], bleeding on probing [BOP], and probing depth [PD]) were assessed at baseline and after 6 months. Statistical analysis was performed using one-way analysis of variance.

RESULTS

Age, gender, and duration and treatment of prediabetes were comparable among patients in Groups 1 and 2. PI, BOP, and PD significantly reduced in both groups than baseline values. Reduction in periodontal parameters among Groups 1 and 2 were comparable. There was no significant reduction in FBG levels among patients in Groups 1 and 2 after 6 months of SRP.

CONCLUSION

SRP was effective in reducing periodontal inflammation in prediabetic patients. FBG levels did not show any significant difference after SRP in both groups.

The potential for glycemic control monitoring and screening for diabetes at dental visits using oral blood

OBJECTIVES

We examined the potential for glycemic control monitoring and screening for diabetes in a dental setting among adults (n = 408) with or at risk for diabetes.

METHODS

In 2013 and 2014, we performed hemoglobin A1c (HbA1c) tests on dried blood samples of gingival crevicular blood and compared these with paired "gold-standard" HbA1c tests with dried finger-stick blood samples in New York City dental clinic patients. We examined differences in sociodemographics and diabetes-related risk and health care characteristics for 3 groups of at-risk patients.

RESULTS

About half of the study sample had elevated HbA1c values in the combined prediabetes and diabetes ranges, with approximately one fourth of those in the diabetes range. With a correlation of 0.991 between gingival crevicular and finger-stick blood HbA1c, measures of concurrence between the tests were extremely high for both elevated HbA1c and diabetes-range HbA1c levels. Persons already diagnosed with diabetes and undiagnosed persons aged 45 years or older could especially benefit from HbA1c testing at dental visits.

CONCLUSIONS

Gingival crevicular blood collected at the dental visit can be used to screen for diabetes and monitor glycemic control for many at-risk patients.

Periodontal Status and Whole Salivary Cytokine Profile Among Smokers and Never-Smokers With and Without Prediabetes

BACKGROUND

Whole salivary interleukin (IL)-1β and IL-6 in smokers and never-smokers with prediabetes remains uninvestigated. The aim of this study is to assess the periodontal status and whole salivary IL-1β and IL-6 levels among smokers and never-smokers with and without prediabetes (controls).

METHODS

Ninety-five males (45 with prediabetes and 50 systemically healthy controls) were included. Twenty-seven controls and 29 patients with prediabetes were smokers. Periodontal parameters (plaque index, bleeding on probing, probing depth, clinical attachment loss, and marginal bone loss) were measured, and the number of missing teeth were recorded. Fasting blood glucose (FBG) and hemoglobin A1c (HbA1c) levels were recorded. Unstimulated whole saliva samples were collected, unstimulated whole salivary flow rate (UWSFR) was determined, and IL-1β and IL-6 levels were measured. P values <0.05 were considered statistically significant.

RESULTS

FBG (P <0.05) and HbA1c (P <0.05) levels were higher among patients with prediabetes than controls. All patients with prediabetes were hyperglycemic. UWSFR was significantly higher among controls than among patients with prediabetes (P <0.05). Periodontal parameters and whole salivary IL-1β and IL-6 levels were comparable among smokers and never-smokers with prediabetes. Among controls, periodontal parameters and whole salivary IL-1β and IL-6 levels were higher among smokers than never-smokers (P <0.05).

CONCLUSIONS

Among controls, periodontal inflammation was worse, and whole salivary IL-1β and IL-6 levels are higher in smokers than never-smokers. Among patients with prediabetes, periodontal inflammation and whole salivary IL-1β and IL-6 levels were comparable between smokers and never-smokers.

Association between glycemic status and oral Candida carriage in patients with prediabetes

OBJECTIVE

This study assessed the association between glycemic status and oral Candida carriage among patients with prediabetes.

STUDY DESIGN

This was a comparative study of oral Candida carriage among individuals with prediabetes. Oral yeast samples were collected from 150 individuals: group A was 43 patients with prediabetes (fasting blood glucose levels and hemoglobin A1c, 100 to 125 mg/dL and ≥5%, respectively); group B was 37 individuals previously considered prediabetic but having fasting blood glucose levels <100 mg/dL and hemoglobin A1c <5%; and group C was 70 medically healthy individuals. Oral yeasts were identified using standard techniques. Unstimulated whole salivary flow rate and number of missing teeth were recorded.

RESULTS

Oral Candida was isolated from 100% of patients with prediabetes and from 65.7% of control participants. Candida albicans carriage was higher among patients with prediabetes (48.7%) (P < .01) and patients in group A (51.2%) (P < .01) than among controls (25.7%). Candida carriage, unstimulated whole salivary flow rate, and number of missing teeth were similar in groups A and B.

CONCLUSIONS

Oral Candida carriage was higher in patients with prediabetes than in controls and was independent of glycemic status in patients with prediabetes.

Self-perceived oral health and periodontal parameters in chronic periodontitis patients with and without rheumatoid arthritis

AIM

It is hypothesized that self-perceived oral health and periodontal status are worse in chronic periodontitis (CP) patients with rheumatoid arthritis (RA) compared to CP patients without RA. The aim of the present study was to assess self-perceived oral health and periodontal parameters in CP patients with and without RA.

METHODS

Fifty CP patients with RA and 50 CP patients without RA were included. Information regarding sociodemographic characteristics and self-perceived oral symptoms were collected using a questionnaire. Periodontal parameters (plaque index, bleeding on probing, probing depth, clinical attachment loss, number of missing teeth, and marginal bone loss) were recorded.

RESULTS

There was no significant difference in socioeconomic status, education status, self-perceived oral symptoms, and periodontal parameters among CP patients with and without RA.

CONCLUSIONS

Self-perceived oral health and periodontal parameters are mainly governed by the intensity of CP, and the role of RA in this context seems to be rather secondary.

Effect of nonsurgical periodontal therapy (with or without oral doxycycline delivery) on glycemic status and clinical periodontal parameters in patients with prediabetes: a short-term longitudinal randomized case-control study

OBJECTIVE

The aim of the present short-term longitudinal randomized case-control study was to assess the effect of nonsurgical periodontal therapy (NSPT) (with and without oral doxycycline delivery) on glycemic status and clinical periodontal parameters in patients with prediabetes.

MATERIAL AND METHODS

Sixty-six patients with prediabetes and periodontal disease were included. Characteristics of the study cohort (age, gender, socioeconomic status [SES] education status, duration of prediabetes, and type of treatment adopted for prediabetes management) were recorded. Patients were randomly divided into two groups (33 patients/group). In group 1, scaling and root planing (SRP) was performed, and in group-2, patients underwent SRP and oral doxycycline (100 mg) administration once daily for 15 days. In each group, the following parameters were investigated at baseline and after 3 months: (a) fasting blood glucose level (FBGL), (b) hemoglobin A1c (HbA1c), and (c) periodontal parameters (plaque index [PI], bleeding on probing [BOP], probing depth [PD], and clinical attachment loss [AL]). Statistical analysis was performed using Student's t test.

RESULTS

There was no significant difference in age, gender, SES, education status, and duration and treatment of prediabetes among individuals in groups 1 and 2. Three months post-NSPT, FBGL and HbA1c were significantly reduced among patients in group 1 (P < 0.05) and group 2 (P < 0.05) compared to baseline. Three months post-NSPT, PI (P < 0.05), BOP (P < 0.05), and PD (P < 0.05) were significantly reduced among patients in group 1 (P < 0.05) and group 2 (P < 0.05) compared to baseline. There was no difference in clinical AL between the groups after 3 months of NSPT.

CONCLUSION

NSPT (with and without oral doxycycline delivery) reduces hyperglycemia and periodontal inflammation in patients with prediabetes.

Potential association between prediabetic conditions and gingival and/or periodontal inflammation

AIMS/INTRODUCTION

Prediabetic conditions, which include impaired fasting glucose (IFG) and impaired glucose tolerance (IGT), might be associated with chronic gingival and/or periodontal inflammation. However, the occurrence of this oral inflammation in prediabetic conditions is poorly understood. The present study aimed to assess the association between prediabetes and gingival and/or periodontal inflammation.

MATERIALS AND METHODS

A total of 94 Puerto Rican men and women aged 40-65 years, who were residents of San Juan, Puerto Rico, and free of diabetes, were included in the study. All participants had at least one tooth site with clinical attachment loss ≥3 mm. Fasting and 2-h plasma glucose were collected. Gingival/periodontal inflammation was assessed by bleeding on gentle probing of the sulcus at six sites per tooth.

RESULTS

Participants with the percentage of teeth with bleeding on probing (BOP) equal to or greater than the median were compared with those with the percentage of teeth with BOP less than median. Participants with high BOP tended to present higher IFG (odds ratio [OR] 5.5, 95% confidence interval [CI] 1.2-25.3) and/or prediabetic condition (OR 3.6, 95% CI 1.0-13.2) than those with a low percentage of BOP, adjusting for age, sex, smoking, alcohol consumption, waist circumference and number of missing teeth. Using the continuous form of the outcome, the corresponding adjusted least squares means of percentage of BOP were 26.8 (standard error of the mean [SEM] 2.3) and 43.8 (SEM 6.0) in normal and IFG, respectively (P = 0.01), and 27.0 (SEM 2.4) and 39.0 (SEM 5.3) among healthy and prediabetic individuals, respectively (P = 0.05).

CONCLUSION

IFG and/or prediabetes are strongly associated with BOP, a marker of chronic gingival/periodontal inflammation.

Whole salivary interleukin-6 and matrix metalloproteinase-8 levels in patients with chronic periodontitis with and without prediabetes

BACKGROUND

The cytokine profile in unstimulated whole saliva (UWS) of patients with prediabetes and chronic periodontitis (CP) remains uninvestigated. The aim of this study is to assess interleukin (IL)-6 and matrix metalloproteinase (MMP)-8 levels in UWS of patients with CP with and without prediabetes.

METHODS

Eighty-eight males (aged 39 to 51 years) were divided into three groups: group 1: 28 patients with CP and prediabetes; group 2: 30 patients with CP and without prediabetes; and group 3: 30 controls. Fasting blood glucose (FBG) and hemoglobin A1c (HbA1c) levels, periodontal parameters (plaque index, bleeding on probing, probing depth, attachment loss, and marginal bone loss), and number of missing teeth were recorded. UWS samples were collected, and UWS flow rate (UWSFR) was measured. IL-6 and MMP-8 were measured in UWS using enzyme-linked immunosorbent assay. P values <0.05 were considered statistically significant.

RESULTS

Mean FBG and HbA1c levels were significantly higher in group 1 (119.3 ± 3.1 mg/dL and 6.1% ± 0.2%) than group 2 (80.1 ± 3.5 mg/dL and 4.8% ± 0.5%; P <0.001) and group 3 (75.3 ± 2.2 mg/dL and 4.3% ± 0.2%; P <0.05). UWSFR was significantly higher in groups 2 (0.53 ± 0.1 mL/minute; P <0.05) and 3 (0.51 ± 0.1 mL/minute; P <0.01) than group 1 (0.33 ± 0.05 mL/minute). Periodontal parameters were worse in group 1 (P <0.05) and group 2 (P <0.05) than group 3. There was no difference in periodontal parameters, numbers of missing teeth, or salivary IL-6 and MMP-8 levels between patients in groups 1 and 2.

CONCLUSION

Salivary IL-6 and MMP-8 levels are elevated in patients with CP with and without prediabetes.

Histomorphometric analysis of bone regeneration using a dual layer of membranes (dPTFE placed over collagen) in fresh extraction sites: a canine model

In untreated extraction sockets, buccal bone remodeling compromises the alveolar ridge width. The aim of this study was to histologically assess the efficacy of using a dual layer of membranes (high-density polytetrafluoroethylene [dPTFE] placed over collagen) for ridge preservation in fresh extraction sites. Eight beagle dogs were used. After endodontic treatment of mandibular bilateral second (P2), third (P3), and fourth (P4) premolars, mandibular bilateral first premolars and distal roots of P2, P3, and P4 were extracted atraumatically. Animals were randomly divided into 4 treatment groups. group 1, the control group, received no treatment; in group 2, allograft was placed in the alveolum and the socket covered with dPTFE membrane; in group 3, allograft was placed in the alveolum, the buccal plate was overbuilt with allograft, and the socket was covered with dPTFE membrane; in group 4, allograft was placed in the alveolum and covered with dual layer of membranes (dPTFE placed over collagen). No intent of primary closure was performed for all groups. After 16 weeks, the animals were sacrificed and mandibular blocks were assessed histologically for buccolingual width of alveolar ridge, percentage of bone formation and bone marrow spaces, and the remaining bone particles. The buccolingual width of the alveolar ridge was significantly higher among sockets in group 4 than in group 1 (P < .05). the amount of newly formed bone in each socket was higher in extraction sockets in group 4 than in groups 1, 2, and 3 (P < .001). A significant difference was found in the percentage of bone marrow spaces among all groups (P < .001). No significant difference was found in the number of nonresorbed bone particles among the groups. Using a dual layer of membrane was more effective in ridge preservation than conventional socket augmentation protocols.

Dental clinics as potent sources for screening undiagnosed diabetes and prediabetes

INTRODUCTION

This pilot study investigated the efficacy of dental clinics as potent sources for screening diabetes and prediabetes in undiagnosed individuals.

METHODS

Data were randomly collected from 385 patients (aged 40 years and older) visiting dental clinics. Patients already having a diagnosis of diabetes and/or prediabetes were excluded. Demographic data, body mass index and family and dental histories were recorded. Signs and symptoms of diabetes were investigated. Random blood glucose levels (RBGLs) were recorded. Individuals with RBGL ≥110 mg/dL underwent the oral glucose tolerance test and the glycosylated hemoglobin test (HbA1c).

RESULTS

Of the 385 patients, 60% (232) had RBGL <110 mg/dL, whereas 40% (153) had RBGL ≥110 mg/dL. Prevalence of confirmed diabetes and prediabetes among the study participants was 16.4% and 15.8%, respectively. Body mass index was significantly higher among patients with diabetes and prediabetes as compared with healthy controls. HbA1c level was statistically significantly higher among patients with diabetes than among patients with prediabetes. Symptoms of polyuria and polydipsia were significantly higher among patients with diabetes than in those without diabetes.

CONCLUSIONS

A high percentage of undiagnosed type 2 diabetes and prediabetes among patients visiting dental clinics was found compared with that reported in the medical literature. Further studies with a lager sample size are needed to confirm these results.

Effect of glycemic control on self-perceived oral health, periodontal parameters, and alveolar bone loss among patients with prediabetes

BACKGROUND

The effect of glycemic control on severity of periodontal inflammatory parameters in patients with prediabetes is unknown. The aim of the present study is to assess the effects of glycemic control on self-perceived oral health, periodontal parameters, and marginal bone loss (MBL) in patients with prediabetes.

METHODS

A total of 303 individuals were included. Hemoglobin A1c (HbA1c) and fasting blood glucose levels (FBGLs) were recorded. Participants were divided into three groups: 1) group A: 75 patients with prediabetes (FBGLs = 100 to 125 mg/dL [HbA1c ≥5%]); 2) group B: 78 individuals previously considered prediabetic but having FBGLs <100 mg/dL (HbA1c <5%) resulting from dietary control; and 3) control group: 150 medically healthy individuals. Self-perceived oral health, socioeconomic status, and education status were determined using a questionnaire. Plaque index (PI), bleeding on probing (BOP), probing depth (PD), and clinical attachment loss (AL) were recorded. Premolar and molar MBLs were measured on panoramic radiographs.

RESULTS

Periodontal parameters (PI, BOP, PD, and AL) (P <0.01) and MBL (P <0.01) were worse among individuals in group A than those in group B. Self-perceived gingival bleeding (P <0.001), pain on chewing (P <0.001), dry mouth (P <0.001), and oral burning sensations (P <0.05) were worse among patients in group A than those in group B. There was no difference in periodontal parameters, MBL, and self-perceived oral symptoms among patients with prediabetes in group B and healthy controls.

CONCLUSIONS

Self-perceived oral health, severity of periodontal parameters, and MBL are worse in patients with prediabetes than controls. Glycemic control significantly reduces the severity of these parameters as well as the state of prediabetes in affected individuals.

Periodontal disease in habitual cigarette smokers and nonsmokers with and without prediabetes

INTRODUCTION

: Prediabetes and habitual cigarette smoking are significant risk factors contributing to periodontal disease. The aim was to assess the clinical and radiological markers of periodontal disease in habitual cigarette smokers and nonsmokers with and without prediabetes.

METHODS

Sixty-eight individuals with prediabetes (test group; 34 smokers and 34 nonsmokers) and 68 medically healthy individuals (control group; 34 smokers and 34 nonsmokers) were included. Sociodemographic information, duration of smoking habit and number of cigarettes smoked daily were recorded through a questionnaire. Fasting blood glucose levels and periodontal inflammatory conditions (plaque index [PI], bleeding on probing [BOP] and probing pocket depth [PPD] of 4 to <6 mm and ≥6 mm) were recorded. In both groups, marginal bone loss (MBL) was measured on digital panoramic radiographs.

RESULTS

Cigarette smokers and nonsmokers in the test group had significantly higher fasting blood glucose level when compared with cigarette smokers in the control group (P < 0.001). In the test group, there was no significant difference in PI, BOP, PPD (4 to <6 mm and ≥6 mm) and MBL among cigarette smokers and nonsmokers. Cigarette smokers in the control group had significantly higher PI (P < 0.001), PPD (4 to <6 mm; P < 0.001), PPD ≥6 mm (P < 0.01) and MBL (P < 0.05) than nonsmokers. BOP was significantly reduced in smokers when compared with nonsmokers in the control group (P < 0.001).

CONCLUSIONS

Cigarette smokers without prediabetes exhibit significantly severe periodontal disease than nonsmokers. In subjects with prediabetes, the severity of periodontal disease seems to be over shadowed by the hyperglycemic state, obscuring the effect of habitual smoking.

Periodontal inflammatory conditions among gutka chewers and non-chewers with and without prediabetes

BACKGROUND

It is known that gutka chewing jeopardizes periodontal health; however, severity of periodontal inflammation in gutka chewers with and without prediabetes remains unknown. The aim of this study is to investigate the association of periodontal inflammatory conditions with gutka chewing and prediabetes.

METHODS

In this cross-sectional study, the effect of gutka use on periodontal health is investigated among 44 individuals with prediabetes and 44 without prediabetes. Demographic information regarding age, sex, duration of prediabetes, and gutka-chewing habits was collected using a questionnaire. Periodontal inflammatory conditions (plaque index [PI], bleeding on probing [BOP], probing depth [PD], marginal bone loss [MBL]) and fasting blood glucose levels (FBGLs) were recorded. Group differences in periodontal inflammatory parameters were tested using univariate and multivariable analyses (α ≤5%).

RESULTS

Periodontal inflammatory parameters (PI, BOP, and PD) were significantly higher in individuals with prediabetes irrespective of gutka-chewing habit (P <0.05). Odds of periodontal inflammation in individuals with prediabetes were nine times higher than in healthy controls (95% confidence interval [CI] = 3.4 to 23.6). Gutka chewing alone, chewing among individuals with prediabetes, and chewing among healthy controls did not significantly increase the odds of periodontal inflammatory conditions. Individuals with prediabetes were significantly more likely to have periodontal inflammation than individuals without prediabetes even after controlling for sex and gutka chewing (odds ratio = 13.2; 95% CI = 4.3 to 40.7).

CONCLUSION

In medically healthy individuals, periodontal inflammatory conditions are worse in gutka chewers compared to non-chewers; in patients with prediabetes, the severity of periodontal inflammation is governed by hyperglycemia when compared to habitual gutka usage.
