Effect of non surgical periodontal therapy and vitamin C supplementation on total antioxidant capacity in patients with chronic generalised periodontitis - A randomised controlled trial.

Background: Periodontal inflammation are inflammation of supporting tissues of periodontium. The microbial factor can cause infection which is polymicrobial in origin and causes dysbiosis and shift in oxidative stress with compromised antioxidant capacity. This study focused at determination of the effect of nonsurgical periodontal therapy (NSPT) and vitamin C supplementation on total antioxidant capacity (TAOC) in chronic periodontitis patients (ChP). Material & method: A total of 70 ChPand 35 periodontally healthy subjects (control) were recruited in this study. Further, ChP group was subdivided into ChP1 group (n = 35) which received NSPT only and ChP 2 group (n = 35) which received NSPT with vitamin C 500 mg once daily for 3 months. Serum and saliva samples were taken at baseline and at 3 months postNSPT for measurement of TAOC. Clinical parameters measured were measured at 1-, 3-, 6- and 12-month interval. Results: Lower levels of serum and salivary TAOC levels were observed in ChP patients than healthy subjects (p < 0.05). Improvement in Clinical parameters was observed in both the groups ChP1 and ChP 2 group post therapy (p < 0.05). The periodontal treatment showed insignificant changes in serum and salivary TAOC levels (p > 0.05). The supplemental dose of vitamin C didn't have any additional benefits (p > 0.05). Conclusion: There lies an association of oxidative stress with periodontitis, low serum and salivary TAOC levels were seen in chronic periodontitis patients. NSPT improved the periodontal inflammatory status. However, benefits of vitamin C as an adjunct to NSPT remains inconclusive and needs to be further explored by multicentre longitudinal studies.

Comparison of Chlorhexidine and Hydrogen Peroxide as Preprocedural Mouthrinse during Ultrasonic Scaling: A Triple-Blinded Randomized Controlled Clinical Trial.

Background: Every year, around 2 million people suffer from hospital-acquired infections worldwide. Aerosols are produced while performing ultrasonic scaling. They are potential source of infection and cross contamination. It can result in spread of several infections including hepatitis, HIV, SARS CoV 2, etc. Preprocedural rinse before scaling is considered an effective measure to reduce the microbial load in aerosols. Materials and Methods: This study was a triple-blinded randomized controlled trial performed on 90 participants diagnosed with chronic periodontitis. Random allocation of participants into three groups, i.e., Group-1, Group-2, and Group-3, was done, wherein 0.12% chlorhexidine (CHX), 1.5% hydrogen peroxide (HP), and distilled water (DW) were used, respectively, as preprocedural mouthrinse. The participants of each group were instructed to perform mouthrinse for 60 s before the start of ultrasonic scaling sessions. Blood agar plates were kept at three locations, i.e., operator's chest area, patient's chest area, and assistant's chest area for aerosol collection after scaling. Colony-forming units (CFUs) were counted for microbiological analysis. Results: Least number of CFUs was found in the CHX group, followed by HP and DW groups. Location wise, the patient's chest area had the highest CFU count and the least was at the assistant's chest area. CFU count between the groups was statistically significant. Conclusion: Preprocedural rinse using HP can effectively be used as a method to reduce dental aerosols generated during ultrasonic scaling.

Role of nonsurgical periodontal therapy on leptin levels and total antioxidant capacity in chronic generalised periodontitis patients - A clinical trial.

INTRODUCTION: Periodontitis causes oxidative stress and reduce total antioxidant levels. The aim of this study was to determine the effect of non-surgical periodontal treatment on leptin levels and total antioxidant capacity in chronic periodontitis. MATERIALS AND METHODS: A total of 35 chronic periodontitis (ChP) patients and 35 systemically and periodontal healthy subjects were enrolled in this study. Further, the ChP group received nonsurgical periodontal therapy (NSPT). Leptin and total antioxidant capacity (TAOC) was measured in serum and saliva samples at baseline, 3 months and 6 months after non-surgical periodontal therapy. Clinical parameters measured were measured at baseline, 1, 3 and 6 months interval. RESULTS: The mean serum leptin and TAOC levels in control group were significantly higher compared to chronic periodontitis group (p < 0.05). The control group had lower mean salivary leptin levels and higher mean salivary TAOC levels as compared to periodontitis group(p < 0.05). Clinical parameters were improved in ChP group post therapy (p < 0.05). However, the periodontal treatment showed insignificant changes in serum and salivary leptin and TAOC levels. CONCLUSION: Chronic periodontitis is significantly associated with serum and salivary TAOC and leptin levels. Non surgical periodontal therapy didn't alter the local and systemic TAOC and leptin levels.

Efficacy of Preprocedural Boric Acid Mouthrinse in Reducing Viable Bacteria in Dental Aerosols Produced during Ultrasonic Scaling.

INTRODUCTION: Aerosols and droplets contaminated with bacteria and blood are produced during ultrasonic scaling. Measures to control aerosol contamination in dental clinics are recommended by the Centers for Disease Control and Prevention. This study aimed to evaluate the efficacy of preprocedural boric acid (BA) mouthrinse in reducing bacterial contamination in dental aerosols generated during ultrasonic scaling. MATERIALS AND METHODS: This was a randomised clinical trial in 90 systemically healthy subjects (25-55 yrs) diagnosed with chronic periodontitis who were allocated into three groups of 30 subjects each to receive, Group A - 0.12% chlorhexidine (CHX), Group B - 0.75% BA and Group C-water, as a preprocedural rinse for 1 min. The aerosol generated while performing ultrasonic scaling for 30 min was collected at three locations on blood agar plates. Incubation of the blood agar plates at 37°C for next 48 h for aerobic culture was performed and subsequently colony-forming units (CFUs) were counted. RESULTS: CFUs in Group A were significantly reduced compared with Group B (P < 0.001). When we compare CFUs in all the three groups, CFUs in Groups A and B were statistically significantly reduced compared with Group C (P < 0.001). Furthermore, it was also observed that the assistant's chest area had lowest CFUs whereas patient's chest area had highest. CONCLUSION: This study recommends routine use of preprocedural mouthrinse as a measure to reduce bacterial aerosols generated during ultrasonic scaling and that 0.12% CHX gluconate is more effective than 0.75% BA mouthwash in reducing CFUs count.

A randomized clinical study to examine the oral hygiene efficacy of a novel herbal toothpaste with zinc over a 6-month period.

OBJECTIVES: This clinical investigation examined the effects of brushing with a test toothpaste containing natural ingredients, that is, clove (Syzgium Aromaticum), aloe vera (Aloe Barbadensis), amla (Emblica Officinalis), neem (Azadirachta Indica), tulsi (Ocimum Basillicum) and honey (from Apis Mellifera) along with zinc salts and fluoride in comparison with a dentifrice formulated with fluoride alone on dental plaque and gingivitis over a 6-month period. MATERIALS AND METHOD: One hundred and eighty (180) subjects with mean plaque index scores greater than 1.5 (Turesky Modified Quigley Hein Plaque Index) and gingival index scores >1.0 (Loe and Silness gingival index) in good general health and who met other study criteria were enrolled in the clinical study. Subjects were evaluated for plaque and gingival index scores and were randomly assigned to perform twice-daily oral hygiene with either the test or the control toothpaste for the next 6 months. One hundred and fifty (150) subjects [test toothpaste (n = 72) and control toothpaste (n = 78)] completed the 6-month clinical study with evaluable data. Post-treatment assessments identical to baseline were conducted after 3-month and 6-month use of an assigned product after subjects refrained from oral hygiene for 12 h prior to each evaluation. Comparisons of the treatment groups with respect to baseline-adjusted gingival, plaque, and bleeding index scores at the follow-up examinations were performed using analyses of covariance (ANCOVA). All statistical tests of hypotheses were two-sided and employed a level of significance of p < 0.05. RESULTS: No significant intergroup differences were noted between treatment groups for age and gender by two-sample t-test and chi-square analyses, respectively (p > 0.05). Furthermore, the treatment groups demonstrated no differences at baseline for plaque, gingival and bleeding index scores by a two-sample t-test (p > 0.05). At 3-month and 6-month examination, the test toothpaste exhibited progressive reductions in plaque, gingival and bleeding scores as compared to control toothpaste as showed by ANCOVA (p < 0.001). In comparison with the control, the test demonstrated reductions in 23.5%, 25.6%, and 73.3% for dental plaque, gingival index and bleeding index outcomes, respectively, at the final visit. Reductions in the frequencies of sites with higher clinical scores were noted over the study with more sites registering improvements in the test group than in the control group. CONCLUSIONS: Routine oral hygiene with the test toothpaste formulated with herbal ingredients and zinc demonstrated a clinical adjunctive improvement in oral hygiene and parameters of gingival health as compared to brushing with a fluoride toothpaste.

Influence of a Low-Carbohydrate and Rich in Omega-3 Fatty Acids, Ascorbic Acid, Antioxidants, and Fiber Diet on Clinical Outcomes in Patients with Chronic Gingivitis: A Randomized Controlled Trial.

BACKGROUND: Nutrition has a significant impact on the pathophysiology of periodontal disease. Both micro- and macronutrients have an impact on periodontal health. This study aimed at the evaluation of the effects of a diet low in carbohydrate and rich in omega-3 fatty acids, ascorbic acid, antioxidants, and fiber on clinical outcomes in patients with gingival inflammation for four weeks. MATERIALS AND METHODS: Overall, 54 systemically healthy subjects were enrolled in this study. The clinical trial consisted of two groups: Group A (test group) (n = 27) was instructed to consume a diet comprising low carbohydrates, rich in omega-3 fatty acids, ascorbic acid, antioxidants, and fibers for the next four weeks; in Group B (control group) (n = 27), no alteration in dietary behavior was done, and these subjects were instructed to have their daily routine diet. Clinical parameters measured were plaque index (PI), gingival bleeding index (GI), probing depths (PD), clinical attachment level (CAL), and bleeding on probing (BOP) at one week without any dietary changes (baseline) for both the groups, followed by a one-week adaptation period; then, the parameters were checked on a weekly basis for the next four weeks. RESULTS: Primary clinical outcome BOP and secondary outcome GI showed significant changes in the test group compared with the control group (P < 0.05). However, no significant changes were seen in the plaque scores in the test group (P > 0.05). The degree of diet compliance on the clinical parameters (PI, GI, and BOP) was assessed by using regression analysis. CONCLUSION: Dietary recommendations can be beneficial in managing gingival and periodontal inflammation. Nutritional interventional studies as monotherapy are required to evaluate the clinical significance of diet in periodontal therapy.

Periosteal pedicle graft with coronally advanced flap and its comparison with modified coronally advanced flap in the treatment of multiple adjacent gingival recessions-a randomized clinical trial.

The present study aimed at evaluating clinical utility of periosteal pedicle graft with coronally advanced flap (PPG â€‹+ â€‹CAF) vs modified coronally advanced flap (M-CAF) in cases of multiple adjacent gingival recessions involving maxillary and mandibular anteriors labially. Random allocation of 40 patients with 269 gingival recessions was done into two groups. In Test group (20 patients) periosteal pedicle graft followed by coronally advanced flap (PPG â€‹+ â€‹CAF) technique was performed and in control group (20 patients) modified coronally advanced flap (M-CAF) was attempted. Primary outcome measures included percentage root coverage (PRC), gingival thickness (GT), probing depth (PD), clinical attachment level (CAL), recession depth (RD) and width of keratinized gingiva (WKG). Secondary outcomes measures were patient centred outcomes, plaque index (PI) and gingival index (GI). Patients were recalled at baseline, 3,6 and 18 months postoperatively. RESULTS: There was a significant decrease in the mean recession depth from 3.58 â€‹± â€‹0.53 â€‹mm (baseline) to 0.22 â€‹± â€‹0.01 â€‹mm (18 months) in PPG â€‹+ â€‹CAF test group and 3.7 â€‹± â€‹0.56 â€‹mm (baseline) to 0.21 â€‹± â€‹0.01 mm (18 months) in M-CAF control group. With 85% root coverage in test group and 78% root coverage in control group, the difference was statistically significant at 18 months. The test group showed significant higher clinical attachment level gain and increase in width of keratinized gingiva as compared to control group. CONCLUSION: In both the study groups PPG â€‹+ â€‹CAF and M-CAF, significant root coverage was achieved. However, in terms of increase in width of keratinized gingiva, gingival thickness and percentage root coverage, PPG â€‹+ â€‹CAF group presented significantly better results than M-CAF group at 18 months follow up. Thus, periosteum can be used as a pedicle graft along with coronally advanced flap as an alternative method in achieving better results with minimal cost.

Diode Laser - A Novel Therapeutic Approach in the Treatment of Chronic Periodontitis in Type 2 Diabetes Mellitus Patients: A Prospective Randomized Controlled Clinical Trial.

Introduction: Maturity-onset diabetes mellitus affecting the elderly population is marked by insulin resistance and decreased insulin production. The relationship between periodontitis and diabetes is bidirectional. Type 2 diabetic patients are more prone to chronic periodontitis (CP) and severe periodontitis affects the glycemic control in such patients. Recently, dental diode laser has become an effective tool in controlling CP. To date, very few studies have been conducted to check the efficacy of diode laser in control of periodontal destruction in type 2 diabetes mellitus (DM2) patients. Hence, the need of the study was to evaluate whether diode laser helps improvement of periodontal outcome and reduction in anaerobic bacteria in elderly diabetic patients with CP. Methods: Forty DM2 patients with CP were randomized into group A (control): scaling and root planing (SRP) only and group B (test): SRP followed by soft tissue dental diode laser (808 nm) application. Four patients (2 in each group) were lost during follow up. Clinical parameters, plaque samples and glycated hemoglobin levels were evaluated at both baseline and 90 days post-treatment. Results: Improvement in clinical, microbiological and glycemic parameters were noted in the group that received SRP as well as SRP + LANAP (laser-assisted new attachment procedure). The reductions in clinical parameters were statistically significant after 3 months (P<0.001). The microbial analysis of plaque samples for Aggregatibacter actinomycetemcomitans (Aa) and Porphyromonas gingivalis (Pg) decreased significantly after 3 months in group B than in group A. Glycated hemoglobin level (HbA1c) decreased significantly after 90 days in both the groups (P<0.001) with more reduction in the SRP+LANAP group (6.49%) in comparison to SRP alone (16.25% vs. 9.76%). However, on the intergroup comparison, the difference in HbA1c reduction was nonsignificant. Conclusion: Laser as an adjunct to SRP is an effective procedure for improving clinical and microbiological parameters in maturity onset diabetes mellitus patients with CP. Also, there was a better improvement in glycemic control in the test group compared to control group after 3 months. Hence, medically compromised patients like DM2 with CP with delayed wound healing can effectively be treated by laser as an adjunct to nonsurgical periodontal therapy for better results.

Solitary plexiform neurofibroma of the gingiva: unique presentation in the oral cavity.

Neurofibromas are benign tumours originating from the nerve sheath. Amongst the histological variants, plexiform types are considered exclusive. These are poorly circumscribed, locally invasive and may exhibit sarcomatous potential. Plexiform neurofibromas are key features of Neurofibromatosis - 1 and their solitary intra-oral presentation is uncommon. The following case report describes a unique case of an isolated solitary plexiform neurofibroma of the maxillary anterior gingival region in a middle aged female patient.

Correlation of periodontal status and bone mineral density in postmenopausal women: a digital radiographic and quantitative ultrasound study.

BACKGROUND: Data suggest that postmenopausal women with osteoporosis are at an increased risk for periodontal attachment loss and tooth loss; however, the extent of relationship between these two diseases is still not clear. AIM: The aim of the study was to evaluate the correlation of periodontal status and bone mineral density (BMD) in postmenopausal women. MATERIALS AND METHODS: The study population included 60 postmenopausal women aged 50-60 years (mean±SD: 55.5±3.4 years). Periodontal status was examined by plaque index, bleeding index, probing depth, and clinical attachment level (CAL). Digital panoramic radiograph was taken to measure the maxillary and mandibular alveolar bone density values. Skeletal (calcaneal) BMD was measured by quantitative ultrasound technique for T-score values. The recorded data for T-score, maxillary and mandibular alveolar bone densities, and periodontal status were subjected to statistical analysis for correlation and regression procedures. RESULTS: The results showed that mandibular alveolar (r=0.907, P<0.001) and maxillary alveolar bone density (r=0.898, P<0.001) had significant positive correlation with calcaneal T-score. Probing depth (r=-0.316, P<0.05), bleeding index (r=-0.277, P<0.05), and plaque index (r=-0.285, P<0.05) showed weak but significant negative correlation with calcaneal T-score and alveolar bone density of both the jaws, whereas CAL showed weak correlation with T-score which could not reach to a statistically significance level (r=-0.221, P>0.05). CONCLUSION: Calcaneal BMD was related to alveolar bone loss and, to a lesser extent, to clinical attachment loss, implicating postmenopausal bone loss as a risk indicator for periodontal disease in postmenopausal women.
