The aim of this study was to investigate the application of electrochemical technology in relation to the electrolysis of water in specific fields, including mouthrinses for the control of periodontal disease and the cleaning of contact lenses. A platinum (Pt) coated titanium (Ti) electrode cell (Pt/Ti cell, Dolki Korea Ltd.) was used for electrochemical experiments. Using the disinfection or oxidation potential of the Pt/Ti cell, sterilized water was prepared for clinical testing. An experimental group used mouthrinses with the sterilized water, where as the control group did not. In the experimental group, the gingival and plaque indices, the probing pocket depth and clinical attachment level all showed statistically significant decreases, but in the control group showed significant increases (P<0.05). The electrochemical sterilization of water using the Pt/Ti cell was also applied for the cleaning of contaminated contact lenses. SEM (Scanning Electron Microscope) data demonstrated that a foreign body adhered to the contract lens could be removed during the electrolysis of water containing the contaminated contact lens.

Background: Hypertension is probably the most important public health problem around the world. People with periodontal disease may be at greater risk of hypertension. The inflammatory effects of periodontal disease help to promote endothelial dysfunction in arteries which may lead to changes in blood pressure. Salivary MMP-8 has been associated with both periodontal disease and prevalent hypertension. Aim of study: This study was conducted to measure salivary matrix metalloproteinase - 8, in relation to periodontal health condition among a group of patients with hypertension in comparison with control group. Materials and methods: Ninety subjects, aged 45-50 years old were included in this study, seeking treatment for chest pain in Ibn-AlBaytar center for cardiac surgical treatments in Baghdad, Iraq. The subjects were divided into study group (45 patient) who were diagnosed to be a hypertensive patient, and a control group (45 subject), with no hypertension. Plaque status was evaluated according to the Silness and Loe, probing pocket depth and clinical attachment level. Unstimulated saliva was collected from all subjects to analyses MMP-8. Result: A high mean value of plaque index, clinical attachment level and probing pocket depth for the study group than the control group with statistically no significant difference. In addition to that, a significant positive correlation between the plaque index and the clinical attachment level among both groups. Salivary MMP-8 level showed a higher level in the study group than in the control group, with statistically significant difference between groups, and a significant positive correlation was detected between salivary MMP-8 with plaque index, among study group, Conclusions: Higher percentage of periodontal diseases was found among patients with blood hypertension. In addition, high level of salivary MMP-8 is potentially associated with periodontal status of the study group.

Introduction: Treatment of periodontal diseases done by surgical therapy depends upon extent and severity of disease. The ultimate goal of periodontal reconstructive surgery is to regenerate tissues destroyed during periodontal disease. Objective: To evaluate the effectiveness of bovine-derived xenograft with collagen membrane in treatment of intrabony defects by comparing it with open flap debridement alone. Methods: This non-randomised controlled trial was conducted after ethical clearance, at Bir hospital from 2018 March to 2019 April. The study recruited 38 patients by convenience sampling, age from 25-44 years, with chronic periodontitis, and willing to sign informed consent. Intrabony defects were treated by open flap debridement with bovine-derived xenograft and bioresorbable collagen membrane (Test group) and open flap debridement alone (Control group). Probing pocket depth, clinical attachment level, gingival recession, oral hygiene status, and gingival status were assessed at baseline and six months. Results: Six months after therapy, in Test group probing pocket depth reduction was 5.2 mm and gain in mean clinical attachment level was 4.3 mm. In Control group, mean probing pocket depth reduction was 3.8 mm and mean gain in clinical attachment level was 2.7 mm. The test treatment resulted in statistically higher probing pocket depth reduction and clinical attachment level gain than Control group. Conclusion: Both therapies resulted in significant probing pocket depth reductions and clinical attachment gains, and treatment with open flap debridement with bovine-derived xenografts and collagen membrane resulted in significantly higher probing pocket depth reduction and clinical attachment gain than treatment with open flap debridement alone.

The aim of this study was to evaluate retrospectively the periodontal conditions of teeth with fixed crowns that had been in place from 3 to 5 years before the study was conducted. Forty individuals were recalled for a follow-up visit. Full-mouth clinical examinations were carried out and Visible Plaque Index (VPI), Gingival Bleeding Index (GBI), Probing Pocket Depth (PPD), and clinical attachment level (CAL) were assessed in 6 sites per tooth. Parallel radiographs were also taken and blindly analyzed by a digital caliper (distance between the apex and the bone crest). BANA tests were performed. A contra-lateral sound tooth was considered the control. Mean values were obtained and Wilcoxon and paired sample t tests were used to compare the test and control sites. Crowns had a mean VPI value of 30.42% as compared to 49.17% for sound teeth. The GBI was 33.33% and 26.25% for test and control teeth respectively. Assessment of PPD revealed values of 2.30 and 2.14 mm, and assessment of CAL revealed averages of 2.02 and 1.89 mm for test and control teeth respectively. The mean values for radiographic distances were 12.73 and 13.67 mm, and for the BANA test, 67.50 and 50.00 for sound and crowned teeth, respectively. Statistically significant differences were observed for all parameters except for CAL and for the BANA test. It may be concluded that, with the methods used in the present study, crowns may be associated with more signs of inflammation, however not with periodontal breakdown.

This study evaluated the effects of mixture of fibrin-fibronectin sealant system(FFSS) and calcium carbonate(CC) in periodontal intrabony defects. Thirty six sites with two or three wall intrabony defect were used. 14 defects treated with periodontal flap surgery were assigned as the control group. 11 defects treated with CC implantation were designed as experimental group 1 and 11 defects, treated with CC and FFSS implantation as experimental group 2. The control and experimental groups all achieved statistically significant improvements in probing depth and clinical attachment level from the baseline (P<0.01). In mean postsurgery probing depth and gingival recession reduction, there were no statiscally significant differences between the experimental groups and the controls. However, mean postsurgery clinical attachment levels of both experimental groups improved significantly more than that of the controls. As a result, we suggest that mixture of FFSS and CC can be used effectively in intrabony defect as osteoconductive materials.

Introduction and objective: Chronic periodontitis is the most common form of periodontal disease. Progression of the disease is due to high levels of pro-inflammatory cytokines. Statins are a class of lipid-lowering drugs that used for cardiovascular disease and stroke. Statins has potential anti-inflammatory effect by blocking intermediate metabolites of the mevalonate pathway. The aim of this study was to evaluate the influence of Lovastatin and Simvastatin in improve the parameters of chronic periodontitis in the population of Khorasan Razavi province. Methods and materials: 40 subjects with chronic periodontitis were selected and informed consent was obtained from participants. Participants were divided into control and experimental groups and we scaling for patients of both groups, then control group without high blood cholesterol and treatment of patients was done without statin drugs and in case groups, patients with blood cholesterol higher than 240 mg/dl with Lovastatin 20 mg/day during 3 month treated. Periodontal indices; such as probing pocket depth (PPD), GI, PI, CAL and bleeding on probing in patients with chronic periodontitis were measured by the examiner before and after treatment in the control group and the experimental group. Also this index were measured 3 months after treatment in both groups by the same person examiner as Blind and dataes were analyzed by statistical software. Results: In this study, Mean ± SD of age was 7.93 ± 43.8 in the control group and the experimental group was 7.72 ± 47.8 and of the 40 patients in the study, 18 were males and 22 were females. Our study showed that the index of GI, CAL, BOP and probing depth were significantly different between the two groups after the intervention (P less than 0.05) and only after the intervention PI index was not significantly different between the two groups (P>0.05). Conclusion: Our findings showed that statins may improve periodontal index in patient with periodontal disease. This is probably because that statins increase bone regeneration and reduced inflammatory parameters such as CRP, MMP-9, TNF-α and the intermediate products.

Background: : Chronic periodontitis is one of the most common form of periodontal diseases which either require non-surgical periodontal therapy or open flap debridement-surgical therapy or both. To date, it is unclear as of how much changes occur after NSPT or OFD and which therapy provides the best outcome in chronic periodontitis having probing pocket depth ≥ 5-7 mm. Aim: The aim of this randomized controlled clinical trial was to evaluate the Probing Pocket Depth and Clinical Attachment Level between NSPT and OFD in chronic periodontitis patients. Materials and Methods: A total of 52 healthy patients with PPD ≥ 5-7 mm were included in the present study. Half of the patients assigned for the NSPT and half in the OFD group. The PPD and CAL were measured at baseline, three and six months. Independent sample t-test was used to compare the change in mean PPD and CAL between NSPT and OFD group at three and six months, respectively. Results: The difference in the mean decrease of PPD between NSPT and OFD group at three and six months were 0.15 mm (P<0.05) and 0.19 mm (P<0.05), respectively. The difference in the mean gain of CAL between NSPT and OFD group at three and six months were 0.03 mm (p>0.05) and 0.12 mm (P<0.05), respectively. Conclusion: Substantial improvement in periodontal status occurred with both the therapies, however, significantly higher decrease in PPD and gain in CAL were seen with surgical therapy.

In the present study, the clinical outcomes obtained using three different protocols of post-operative plaque control for the 4 weeks after surgery were compared. Thirty healthy subjects, presenting at least one periodontal pocket requiring resective surgery, were selected and randomly distributed to three different groups corresponding to respective post-surgical protocols: (A) toothbrushes + chlorhexidine + anti-discoloration system (ADS + CHX); (B) toothbrushes + chlorhexidine (CHX); (C) only toothbrushes. The full-mouth plaque score (FMPS), full-mouth bleeding score (FMBS), probing pocket depth (PPD), recession depth (REC), clinical attachment level (CAL), and bleeding on probing (BoP) were measured in six aspects per tooth (mesio-buccal (MB), buccal (B), disto-buccal (DB), disto-lingual (DL), lingual (L), and mesio-lingual (ML)) at baseline, 3 months, and 6 months after surgery. FMPS and FMBS did not significantly change (p > 0.05), whereas PPD and CAL significantly decreased, and REC significantly increased in all groups during the study (p < 0.05). Clinical results were satisfactory in all cases, with no significant differences between groups 3 months after surgery. Six months after surgery, only PPD-MB was significantly different in the three groups (p < 0.05). Nevertheless, this value was not clinically relevant because the value of PPD-B (about 2 mm) in group C was physiologic. The mechanical plaque control was proven to be fundamental and sufficient in all the six aspects per tooth to guarantee an excellent clinical outcome without the need of chemical plaque control.

ntroduction: Periodontitis is a multifactorial disease, which, when not adequately treated, is followed with progressive attachment loss which leads to tooth mobility and eventually tooth loss. Periodontal regenerative surgery aims to regenerate and reconstruct the lost periodontal tissue. Regeneration with novabone putty has shown to be effective in reducing probing pocket depth, gain in clinical attachment level and increase in horizontal bone level. Aim: This interventional clinical trial was to evaluate the osseous regenerative potential of a calcium phosphosilicate bioactive glass NOVABONE TM in the treatment of horizontal bone defects. Materials and method: A total of 20 sites with horizontal bone defect was treated with open flap debridement with intra marrow penetration and novabone putty. Statistical analysis: Plaque index, gingival index and radiographic determination were analysed by paired t test. Probing pocket depth and clinical attachment levels were analysed by Wilcoxon Signed Ranks Test. Result: There was significant reduction seen in plaque index, gingival index, probing pocket depth and radiographic crestal level when compared between baseline and 12 months respectively (2.48 ± 0.44, 2.92 ± 0.39, 6.80 ± 0.89, 8.29 ± 0.87) and (1.89 ± 0.42, 1.92± 0.51, 3.00± 0.67, 5.48 ± 0.89) and significant gain in clinical attachment level from 4.40 ± 0.96 to 1.20 ± 0.91. Conclusion: The present study showed novabone putty significantly improved the clinical parameters in horizontal bone defects.

Abstract Aim The aim of this study was to evaluate and compare the efficacy of subgingivally delivered 10% doxycycline hyclate and xanthan based chlorhexidine gels when used as an adjunct to scaling and root planing (SRP) in the treatment of chronic periodontitis. Methods and Materials A randomized, controlled, single center study was conducted involving 90 sites in 30 patients suffering from moderate to advanced chronic periodontitis. Each patient contributed three sites which were randomized to three treatment groups: SRP + insertion of doxycycline gel [SRP+DH], SRP + insertion of chlorhexidine gel [SRP+CHX]), and SRP alone [SRP]. Gingival index (GI), plaque index (PI), probing pocket depth (PPD), and clinical attachment level (CAL) were recorded at baseline, 1 month, and 3 months post therapy. Results All treatments showed significant reductions in PPD and CAL at 1 and 3 months when compared to baseline values (p<0.001). At 3 months, sites treated with SRP+DH and SRP+CHX showed an additional reduction in PPD of 0.86 ± 1.0 mm and 0.66 ± 1.58 mm, respectively, significantly greater than SRP alone (p<0.02). Differences in mean PPD reduction between SRP+DH and SRP+CHX were not significant (p=0.46). At 3 months, differences in relative CAL between both SRP+DH (0.80 ± 0.92) and SRP+CHX (0.63 ± 1.47) and SRP alone were statistically significant (p<0.02). Differences in relative CAL between SRP+DH and SRP+CHX were not significant (p=0.54). Conclusion The results suggest treatment with 10% doxycycline hyclate and xanthan based chlorhexidine gels as an adjunct to SRP improves PPD and CAL patients with periodontitis compared to SRP alone. Clinical Significance The use of local drug therapy may refocus the need for surgical periodontal therapy toward deeper pockets. Citation Gupta R, Pandit N, Aggarwal S, Verma A.

Background. Treatment of gingivitis in patients undergoing orthodontic treatment is done through different methods. Anti-inflammatory agents present in toothpaste or mouthwash are applied spontaneously by patients or used as professional treatment protocols. The present study aimed to investigate the gingivitis effectiveness of Emulgel containing 2% resveratrol in orthodontic patients. Methods. The study was conducted in three groups, namely, experimental, placebo, and control. In the experimental group, participants used an Emulgel containing 2% resveratrol. In the placebo group, subjects used an identical Emulgel without the active components in the test formulations. After brushing their teeth, the participants learned how to use 5 ml of Emulgel on the gums and massage every night for 30 s. In the control group, subjects were instructed to massage their gums for 30 s every night without any product. Evaluated criteria included bleeding on probing (BOP), gingival index (GI), hyperplastic index (HI), and probing pocket depth (PPD). Result. During 4 and 8 weeks of the study, the PPD score in the control group did not change significantly but decreased in both groups. Also, there was a decrease in the PPD score in the experimental group compared to the placebo and control groups. Similarly, in the experimental group, continuous use of Emulgel containing 2% resveratrol reduced the HI and GI scores significantly at 4 and 8 weeks after the start of the study. Here, the decrease in GI and HI scores in the experimental group was higher than that of the other groups. Conclusions. The Emulgel containing 2% resveratrol is effective in improving gingival health in orthodontic patients and can lower gingival inflammation over 8 weeks. This trial is registered with the Iranian registry of clinical trials (https://irct.ir/) IRCT20130812014333N91.
