In a previous study in dogs, the early removal of expanded polytetrafluoroethylene (ePTFE) membrane (2 weeks after placement) showed histomorphometric results (of new bone, cementum and periodontal ligament) similar to that obtained with membrane removal at 4 weeks after placement. This study evaluated the influence of early removal of an ePTFE membrane on the treatment of Class II furcation defects. Twelve patients who provided 12 pairs of mandibular furcation defects were recruited for the study. Baseline clinical measurements were recorded: plaque index (PI), gingival index (GI), bleeding on probing (BOP), probing depth (PD), gingival margin position (GMP) and relative clinical attachment level (RCAL). Full flaps were elevated and hard tissue measurements were performed during the surgery: relative vertical (RVBL) and horizontal (RHBL) bone level. The ePTFE membranes were adapted and sutured to their correspondent tooth and removed at 2 weeks in the test group (TGr) and at 4 weeks in the control group (CGr). After 1 year all sites were re-entered, and soft and hard tissue measurements were recorded. There were no statistically significant differences between TGr and CGr for any baseline measurement. After 12 months, there were no statistically significant differences between TGr and CGr in the PD (p=0.74), GMP (p=0.76) and RCAL (p=0.44) values. However, the RHBL resolution was significant for both groups (CGr p=0.01 and TGr p=0.02), without difference between groups (p=0.39). Early removal of membranes did not affect the outcome on the treatment of Class II furcation defects.

Background: In periodontal therapy, furcation defects are one of the most therapeutically challenging periodontal therapies. Till now various treatment methods have been tried which have shown different success rates. The present study was undertaken to compare the efficacy of bioactive glass (alloplast) with Freeze dried bone allograft (FDBA) in the treatment of Class II furcation defects. Materials and Methods: Twenty patients were selected for the study which had bilateral Class II furcation defects in molars from which ten patients were male and ten patients sere female in the age group of 45-55 years. Various clinical measurements were recorded at three times i.e. at baseline, at one month and at six months post surgery which included the Turesky-Glimore-Glickman modification of the Quigley Hein plaque index, the Loe and silness gingival index, relative clinical attachment level vertical probing depth in the mid-furcation area, and horizontal probing depth in the furcation area. The statistical analysis was done using SPSS version 23.0. Results: In the relative clinical attachment levels, the mean gain in the test and control groups was 2.45 and 1.58 mm, respectively at the end of six months. In the horizontal probing depth values, the mean change in the bioactive glass graft and freeze dried bone allograft was 1.45 and 1.33 mm, respectively. Conclusion: From our study it was concluded that efficacy of Bioactive glass is much better as compared to Freeze dried bone allograft in the treatment of Class II furcation defects.

Abstract The use of bone replacement grafts with barrier membranes in class II furcation defects are aimed at improving the outcome of the regenerative technique. In this regard, however, there is a paucity of studies comparing the results obtained with bone grafts alone or in combination with barrier membranes. The aim of this study was to clinically compare an anorganic bovine bone graft plus 10% collagen (BO) with or without a bioresorbable collagen barrier (BG) in human mandibular molar class II furcation defects. Methods and Materials Twenty mandibular class II furcation defects (ten patients with bilateral defects) were treated either with BO (group I) or a combination of BO/BG (group II). Each defect was randomly assigned to either group I or group II. The soft tissue and hard tissue measurements including vertical probing depth (VPD), horizontal probing depth (HPD), clinical attachment level (CAL), gingival recession (GR), vertical depth of furcation defect (VDF), and horizontal depth of furcation defect (HDF) were recorded at baseline and six months after surgery. Results Both treatment procedures resulted in statistically significant reduction in VPD and HPD, gain in CAL, and reduction in VDF and HDF. There was a statistically significant difference between group I and group II in all soft and hard tissue parameters with the exception of VPD reduction and gingival recession. Conclusion The findings of this study suggest superior clinical results with BO/BG treatment when compared to BO treatment in mandibular class II furcation defects.

Background: Treatment of furcation involvement of molars with periodontal disease remains challenging and unpredictable. Platelet-rich fibrin (PRF) has received the attention of researchers due to its pleiotropic properties essential for periodontal wound healing. The osteoinductive property of demineralized freeze-dried bone allograft (DFDBA) has been successfully used in periodontal regeneration. Aim: The present study aimed to explore the effectiveness of PRF alone and with DFDBA in the treatment of mandibular degree II furcation defects in subjects with chronic periodontitis. Material and Methods: Patients treated were from the Department of Periodontology and Implantology, Institute of Dental Sciences, Bareilly. A total of 60 mandibular molars were treated with either open flap debridement (OFD) alone, [Formula: see text] combination or [Formula: see text] combination. The soft and hard tissue parameters such as vertical probing depth (VPD), vertical clinical attachment level (VCAL), gingival marginal level (GML), horizontal probing depth (HPD), vertical bone fill (VBF), horizontal bone fill (HBF) and furcation width (FW) were determined at baseline and 9 months postoperatively. A paired [Formula: see text]-test was conducted to assess the statistical significance between time period within each group for clinical and radiographic parameters. ANOVA and post-hoc Tukey’s tests were also conducted for intergroup comparison of soft and hard tissue parameters. Statistical significance was set at [Formula: see text]. Results and Discussion: After 9 months, all treatment groups showed significant ([Formula: see text]) improvement in soft and hard tissue parameters, except GML in all the three groups and HBF and FW in the OFD group as compared to baseline. The mean VBF change was highest in the [Formula: see text] group ([Formula: see text]) mm, followed by that in the [Formula: see text] and OFD groups ([Formula: see text] and [Formula: see text][Formula: see text]mm, respectively). Conclusions: It was shown that both [Formula: see text] and [Formula: see text] combinations were significantly advantageous for the management of mandibular degree II furcation defects. However, the [Formula: see text] combination has significantly greater benefits than [Formula: see text] combination in terms of VBF.

Absorbable porcine collagen membrane with a bovine bone graft can be considered for regenerative treatment in periodontal class II furcation defects. We evaluated the clinical efficacy of guided tissue regeneration (GTR) treatment with bovine bone xenograft and a porcine collagen membrane in molars with class II furcations. Probing depth (PD), clinical attachment level (CAL), and bone level (BL) were recorded at baseline and at 3, 6, and 9 months postoperatively. Thirty class II furcation defects from the lower and upper molars were assessed. Significant improvements in PD and CAL were observed from baseline to 9 months in all groups (p < 0.01). BL improved in all groups except group A in the upper molars in radiographic assessment (p < 0.05). The lower and upper molars showed PD reduction of 50.5% ± 7.44% and 46.2% ± 11.2%, respectively, at 9 months (p = 0.044). In furcations of 1–3 mm, the lower and upper molars showed PD reductions of 51.2% ± 4.49% and 36.5% ± 16.14%, respectively (p = 0.035). The lower and upper molars showed a CAL gain of 51.1% ± 4.64% and 33.6% ± 18.8%, respectively (p = 0.037). Thus, GTR with bovine bone graft and porcine collagen membrane yielded good results in class II furcations, with better results in the lower than in the upper molars.

Background: Mangosteen and propolis extracts (MAEC) have been potential therapeutic agents known to exhibit powerful antioxidant and anti-inflammatory properties. The aim of the current study was to evaluate the clinical and immunological efficacy of MAEC as well as safety and patient-reported outcomes (PROMs) on gingivitis and incipient periodontitis. Methods: This study was performed on 104 patients diagnosed with gingivitis or incipient periodontitis. At baseline, the participants were randomly allocated to either the test group, with daily intake of a single capsule containing 194 mg of MAEC for eight weeks, or control group, with placebo. Clinical periodontal evaluation and immunological parameters from saliva and gingival sulcular fluid were assessed at baseline, four, and eight weeks. Individual PROMs were assessed by OHIP-14 questionnaires. Results: There was a significant difference of modified gingival index at four and eight weeks between the test and control groups. In the test group, crevicular interleukin (IL)-6 was reduced, and the salivary matrix metalloproteinase (MMP)-9 was increased after eight weeks. PROMs were improved up to four weeks compared to placebo. Conclusion: Oral administration of MAEC would have a potential to reduce gingival inflammation clinically and immunologically in the patients with gingivitis and incipient periodontitis.

Abstract Background This study was aimed to investigate if the adjunctive use of erythritol air-polishing powder applied with the nozzle-system during subgingival instrumentation (SI) has an effect on the outcome of non-surgical periodontal treatment in patients with moderate to severe periodontitis. Methods Fourty-two individuals with periodontitis received nonsurgical periodontal therapy by SI without (controls, n = 21) and with adjunctive air-polishing using nozzle + erythritol powder (test, n = 21). They were analyzed for the clinical variables BOP (primary outcome at six months), probing depth (PD), attachment level, four selected microorganisms and two biomarkers at baseline, before SI as well as three and six months after SI. Statistical analysis included nonparametric tests for intra- and intergroup comparisons. Results In both groups, the clinical variables PD, attachment level and BOP significantly improved three and six months after SI. The number of sites with PD ≥ 5 mm was significantly lower in the test group than in the control group after six months. At six months versus baseline, there were significant reductions of Tannerella forsythia and Treponema denticola counts as well as lower levels of MMP-8 in the test group. Conclusions Subgingival instrumentation with adjunctive erythritol air-polishing powder does not reduce BOP. But it may add beneficial effects like reducing the probing depth measured as number of residual periodontal pocket with PD ≥ 5 mm when compared with subgingival instrumentation only. Clinical relevance The adjunctive use of erythritol air-polishing powder applied with the nozzle-system during SI may improve the clinical outcome of SI and may reduce the need for periodontal surgery.

Removal Capacity

The aim of this study was to compare the efficacy of dental plaque removal by brushing with and without conventional dentifrice. Twenty-four students aged 17 to 28 years participated in this randomized controlled clinical trial. Quadrants 1-3 or 2-4 were randomly allocated to the test group (brushing without dentifrice) or control group (brushing with dentifrice). After 72 h of cessation of oral hygiene, Quigley & Hein (Turesky) plaque index was assessed before and after brushing by a calibrated and blind examiner. Overtime and intergroup comparisons were performed by Student's paired sample t-test at 5% significance level. The results showed that both groups after toothbrushing presented statistically significant reductions in plaque, with no differences between them (from 3.06 ± 0.54 to 1.27 ± 0.26 versus from 3.07 ± 0.52 to 1.31 ± 0.23). A separate analysis of the buccal and lingual aspects also showed no significant differences between groups. It may be concluded that the use of a conventional dentifrice during toothbrushing does not seem to enhance plaque removal capacity.

Mechanical surface treatment and removal of the above and subgingival biofilm (Tartar ablation; SRP) are considered the most suitable tools for the treatment of periodontal inflammatory diseases, with the aim of destroying bacterial bioflim, reducing bacteria, and slowing down recolonization by pathogenic microorganisms. Often, however, the only S&RP are not enough, as there are patients who are experiencing relapses. Recently, laser therapy has been suggested as a potential tool to improve the outcome of periodontal non-surgical treatment. The objective of the following study was to evaluate the clinical healing of periodontal pockets treated with mechanical therapy, scaling and root planing, and diode laser application, compared to that obtained with non-surgical mechanical therapy alone. The study was designed as a randomized controlled clinical trial. Patients in the control group (13 patients) underwent conventional non-surgical therapy only, while patients in the test group (17 patients) were associated with conventional non-surgical treatment, a laser irradiation session. At baseline and after 6 months, the parameters of probing depth (PD), bleeding on probing (BOP), gingival recession (REC) were assessed The main variable of this study was the PD (probing depth) FMPS and FMBS at follow-up improved in both groups. The FMPS baseline test group 32.59 ± 6.74 - follow up 12.00 ± 3.16. The baseline of the control group showed 33.00 ± 9.55, the follow up 13.15 ± 4.85 The FMBS baseline test group found 24.29 ± 5.01 while at follow 9.65 ± 2.69. The baseline control group 30.31 ± 7.74, Follow up 11.08 ± 2.33. There is a statistical significance. (P.VALUE 0.0001) There were no significant differences between the groups in terms of PD, CAL and BOP at baseline and at follow-up. PD Test group 4,89±1,58 3,95±0,85 0,0001 Control group 5,02±1,57 4,01±0,86 CAL (mm)Test group 0,89±2,29 0,77±1,91 Control group 0,28±1,38 0,24±1,14 REC Test group 0,19±0,49 0,19±0,51 Control group 0,06±0,29 0,57±029 BOP Test group 51,2% 23,5% Control group 54,0% 20,9% The results showed differences in both baseline and follow-up for REC. Test group 0,19±0,49 0,19±0,51-Control group0,06±0,29 0,57±029 In intra-group analyzes, there are differences between baseline and follow-up for all values, except for REC in the control group. The diode laser can be used as an appropriate device for periodontal treatments, but it can offer additional and significant benefits if used according to appropriate protocols and parameters, and especially if associated with non-surgical, manual and ultrasound periodontal instrumentation, always site-specific , as it is a tool that does not replace traditional methods.

Gate Control Theory

Background. The ‘‘gate control’’ theory suggests pain can be reduced by simultaneous activation of larger diameter nerve fibers using appropriate coldness, warmth, rubbing, pressure, or vibration. This study investigated the efficacy of a device combining cold and vibration, for needle-related procedural pain in children. Methodology. A total of 51 children aged 5–12 years participated in this randomized controlled clinical trial. Half of the children were in the control group and received maxillary buccal infiltration, by injecting 1.8 ml of 2% lidocaine with 1 : 100,000 adrenaline using topical anesthesia 20% benzocaine gel for 15 seconds, while the other half were in the test group and received the same anesthesia using a commercially available external cold and a vibrating device. A face version of Visual Analogue Scale (VAS) was used as a subjective measure to assess the child’s pain experience. The parents were requested to evaluate the child’s ability to tolerate pain using a behavioral/observational pain scale. Sound, Eyes, and Motor (SEM) scale and Faces, Legs, Activity, Cry, and Consolability (FLACC) scale were used to record the child’s pain as perceived by the external evaluator. T-test or Mann–Whitney U-test was used for scale variables, paired sample T-test or Wilcoxon rank t-test was used for before and after data, and chi-square was used for categorical variable, based on the results of normality test. Results. The results showed a statistically significant reduction in pain after the injection for the test group compared with control using VAS scale (mean = 6.68 (1.09) and 8.42 (0.50); p = 0.001 ) and FLACC scale (mean = 5.92 (1.05) and 8.16 (0.54); p = 0.002 ), but not when using SEM scale (mean 3.22 (0.42) and 4.24 (2.74); p = 0.08 ). Conclusions. Combined external cold and vibrating devices can be an effective alternative in reducing experienced pain and fear in children undergoing infiltration dental anesthesia. This study was registered with clinical trial registry of the United States National Institutes of Health (NIH) at ClinicalTrials.gov (NCT03953001).

Aim. To compare implant survival rate and marginal bone loss (MBL) of immediately loaded single implants inserted by using ultrasonic implant site preparation (UISP) (test) and conventional rotary instrumentation (control). Methods. Two single implants were inserted for each patient: after randomization, test site was prepared by using an ultrasonic device (Piezosurgery Touch, Mectron, Italy) and control site was prepared by using the drills of the selected implant system (Premium AZT, Sweden & Martina, Italy), until reaching a final diameter of 3 mm in both groups. Identical implants (3.8x11.5 mm) were inserted in all sites at crestal level. Impressions were taken and screwed resin single crowns with platform-switched provisional abutments were delivered with 48 hours. Periapical radiographs were taken at provisional crown insertion (T0), 6 months (T1) and one year (T2) after prosthetic loading to measure MBL. All data were tested for normality and subsequently analyzed by paired samples t-test and forward multiple linear regression. Results. Forty-eight patients were treated in six centers with the insertion of ninety-six implants (48 test; 48 control). Four implants in four patients failed within the first six months of healing (two in test group; two in control group; no difference between groups). Forty patients (age 60.1±10.7 years; 22 female, 18 male) were included in the final analysis. Mean MBL after six months of loading was 1.39±1.03 mm in the test group and 1.42±1.16 mm in the control group (p>0.05) and after one year was 1.92±1.14 mm and 2.14±1.55 mm in test and control, respectively (p>0.05). Conclusions. No differences in survival rate and MBL were demonstrated between UISP and conventional site preparation with rotary instruments in immediately loaded dental implants: UISP, with its characteristics of enhanced surgical control and safety in proximity of delicate structures, may be used as a reliable alternative to the traditional drilling systems.
