Clinical Efficacy of the 940-nm Diode Laser in the Treatment of Recurrent Pockets in the Periodontal Maintenance Phase

Introduction: The basis of periodontal treatments is the mechanical removal of bacterial biofilm, which is often not sufficient. Therefore, laser therapy can be effective as an adjunct treatment. The aim of the present study was to evaluate the clinical efficacy of the 940-nm diode laser in the treatment of recurrent pockets of patients in the periodontal maintenance phase. Methods: The present clinical trial study was performed on 20 patients. Clinical indices, including bleeding index (BI), probing pocket depth (PPD), and clinical attachment level (CAL) of the studied teeth were recorded before the test. The different quadrants were randomly divided into two experimental (scaling and root planing (SRP)+Laser) and control groups (SRP alone). Both groups were matched in terms of plaque index (PI). Clinical indices were re-recorded using therapeutic methods 30 and 90 days after the treatment, and data analysis was carried out using the t test and LSD. Results: There were no significant differences in PI, PPD, CAL, and BI in both groups before the treatment (P>0.05). However, there were significant differences in PPD, CAL, and BI in the two groups one month after the treatment (P<0.05); it means that improvements were more significant in the experimental group than in the control group. Comparing experimental and control groups, we found that there were no significant differences in PPD and CAL indices three months after the treatment (P>0.05); however, there were significant improvements in the BI index in both groups (P<0.05), so that the improvement was better in the experimental group than the control group. Conclusion: Both SRP+Laser and SRP alone improved clinical indices in patients. In short-term follow-up, the effect of SRP+Laser treatment on BI, CAL, PPD was significantly superior to SRP treatment alone, but in long-term follow-up, SRP+laser was more effective than SRP alone in improving the BI index.

Effect of Pudilan Keyanning antibacterial mouthwash on dental plaque and gingival inflammation in patients during periodontal maintenance phase: study protocol for double-blind, randomised clinical trial

IntroductionPlaque control plays a critical role in the prevention and treatment of periodontitis. Antibacterial mouthwash is one of the most important tools for plaque control. Pudilan, including extracts of Scutellaria baicalensis root, Taraxacum mongolicum, Bunge corydalis herb and Isatis indigotica, was reported playing the role of anti-inflammatory and anti-bacterial. However, its effect on dental plaque and periodontal inflammation remains unknown. We aimed to assess the efficacy of Pudilan Keyanning antibacterial mouthwash which contains the active essence of Pudilan and 0.03%–0.06% cetylpyridinium chloride, as well as Pudilan active essence for plaque control and gingival anti-inflammation in patients during periodontal maintenance phase.Methods and analysisIn this double-blind, randomised, placebo-controlled clinical trial, a total of 120 participants during periodontal maintenance phase will be enrolled. After supragingival scaling, they will be randomly assigned into three groups in a 1:1:1 ratio: the Pudilan Keyanning antibacterial mouthwash group, a chlorhexidine acetate mouthwash (0.12%) group or a placebo group with mouthwash containing the same components as the Pudilan Keyanning mouthwash except for Pudilan active ingredients. They will rinse with mouthwash, respectively, two times per day for 6 weeks. Clinical parameters (such as plaque index, bleeding index) and the level of volatile sulfide in the breath will be measured and analysed. The subgingival plaque will be collected and analysed microbiologically. Questionnaire feedback will be analysed.Ethics and disseminationThe study protocol (V.4) was reviewed and approved by the Medical Ethical Committee of Peking University School and Hospital of Stomatology (Ethics Approval No. PKUSSIRB-201950153b). All participants signed a written consent form.Trial registration numberChiCTR2000041253.

Perio-Prosthodontics Considerations in Removable Partial Denture: The Role of the Prosthodontist

OBJECTIVE: To review the periodontal considerations associated with removable partial denture therapy. METHODOLOGY: Using a MEDLINE search, for "removable partial dentures periodontal", a total of 712 papers from peer-reviewed journals came in results. The MEDLINE search was made more specific by applying filters to the key phrase with other key words such as "periodontal evaluation"(140), "direct retainers"(77), "non-surgical periodontal"(8), "surgical periodontal"(180), "plaque"(249), "periodontal indices"(112), "tooth mobility,"(180) "periodontal maintenance,"(60) "splinting,"(198) and "split major connector"(2). Both in vivo and in vitro studies on the Perio-prosthodontic aspects of RPD treatment were included in the study pool whereas case Series and case reports were excluded. RESULT: A total of 1206 studies were collected from the search engine. After applying the exclusion criteria and filtering the duplicates a total of 95 studies were included for the narrative review. CONCLUSIONS: Out of all the factors, recall and oral and denture hygiene have the utmost importance. KEYWORDS: Perio-prosthodontics, removable partial denture, periodontal indices.

Management of an Extrusive Luxation Concomitant with Subluxation: A Case Report with Ten-Year Follow-Up

Traumatic dental injuries (TDIs) are a public health concern with high prevalence and incidence rates. Proper intervention can significantly reduce the subsequent complications of these events. This case report describes the clinical interventions to manage a patient with traumatized maxillary incisor with severe extrusive luxation. The procedure was aimed at preserving pulp vitality and providing periodontal maintenance to the highest possible degree. Owing to timely and accurate treatments, ten years of success have been achieved in this patient, as discussed in this case report.

The effect of Topical Application of Honey Based Gel Containing Zingibar Officinale for Non Surgical Periodontal Maintenance

Introduction: Ginger and honey have shown to be effective against pathogens routinely encountered in periodontal infection. However, none of literature has shown antibacterial effect of ginger and honey on the levels of dental plaque when used as a gel. Aim: To compare the effect of honey with ginger extract on the dental plaque levels and gingival health. Methodology: Fifteen systemically healthy patients were randomly allocated to either the test group [G1(ginger and honey gel = 15 sites)] or the control group [G2 (Chlorhexidine gel = 15 sites]. Full mouth Gingival Index (GI) Full mouth Plaque Index (PI) were evaluated at baseline and on 7th day. Results: The mean PI at baseline was 0.23 ± 0.02 (G1) and 0.29 ± 0.01 (G2) which was increased to 0.36 ± 0.01 (G1) and 0.37 ± 0.01 (G2) on 7th day. However, mean GI at baseline was 0.30 ± 0.04 (G1) and 0.34 ± 0.02 (G2) which was increased to 0.38 ± 0.03 (G1) and 0.43 ± 0.03 (G2) on 7th day. Conclusion: The results of this study suggest that the chlorhexidine gel and Natural gel containing Honey and Zingibar officinale both are effective in controlling plaque during the periodontal maintenance period.
