Passive Root Coverage Through Creeping Attachment of the Gingiva Before and After Scaling and Root Planning Therapy in the Mandibular Anterior Teeth: A Clinical Study.

Introduction Root coverage is one of the most imperative procedures in periodontal therapy. The demands from patients for aesthetics and sensitivity are some of the complaints in root exposure cases. Creeping attachment is a passive apical migration of the marginal gingiva and can be proposed as a noteworthy root coverage technique. The purpose of this study was to evaluate the position of the marginal gingiva and quantify the creeping attachment before and after the scaling and root planning (SRP) procedure. Materials and methods The present study was based on a single-centre clinical trial in which 30 sites from 10 patients were selected. Patients with Miller's class I gingival recession were selected. The plaque index, gingival biotype, and gingival margin position were measured at baseline and then at 10 and 21 days after SRP. The gingival biotype was measured with an endodontic file with a stopper and a digital vernier calliper. The gingival margin position was measured from the incisal surface of the tooth to the marginal gingiva with the help of a University of North Carolina (UNC) 15 periodontal probe. After recording the clinical parameters, a thorough SRP was performed using an ultrasonic scaler and manual instruments. Results The results were compared clinically at baseline and after 10 days and 21 days postoperatively. Statistical analysis was conducted for pre-SRP and post-SRP findings using the IBM SPSS Statistics for Windows, Version 19 (Released 2010; IBM Corp., Armonk, New York) software. A statistically significant improvement was seen in all the clinical parameters at baseline, at 10 days, and at 21 days postoperatively after the procedure (P < 0.01). Conclusion The position of the gingival margin was shifted towards the crown, and the creeping attachment was significantly observed from baseline to 10 and 21 days. Clinical significance Creeping attachment after the SRP procedure can be considered a significant root coverage technique. The genetic memory of the gingiva may play an important role in achieving root coverage. Once local irritants are removed, the gingiva attempts to regain its original position. In addition, the gingival phenotype plays an important role in gingival marginal positioning after basic therapy and root coverage procedures.

Comparative Study of Azithromycin Versus Doxycycline Effect on the Resistin Level in Periodontitis Patients With Type 2 Diabetes: A Randomized Controlled Clinical Trial.

AIM: The present study aimed to determine if azithromycin (AZM) and doxycycline therapy, as an adjunct to scaling and root planning (SRP), modulate host response and improve clinical outcomes in periodontitis patients with type 2 diabetes mellitus (T2DM). PATIENTS AND METHODS: Forty-five periodontal sites in 15 periodontitis patients with T2DM received nonsurgical periodontal therapy (NSPT). In Group I, patients were placebo (not receiving any medication), Group II patients received systemic AZM therapy (AZM 250 mg/day for five days), and Group III patients received doxycycline (20 mg twice per day for three months. The resistin level was collected and measured by enzyme-linked immunosorbent assay (ELISA). Gingival index (GI), probing depth (PD), and clinical attachment level (CAL) were recorded at baseline, one-month, and three-month intervals. RESULTS: All groups showed improvement in clinical parameters and resistin levels throughout the study. The mean resistin level at three months was the highest in Group I and the lowest in Group III. Patients in Group II showed a larger decrease in mean PD than those in Group I and III. Group III had the highest gain in mean CAL, with an increase of 1.78 mm in attachment. CONCLUSION: Resistin might be a useful indicator of current disease status. In addition, benefits from adjunctive systemic use of AZM and doxycycline have been administered with non-surgical periodontal therapy.

Should supragingival scaling be performed separately prior to subgingival scaling and root planning in nonsurgical periodontal therapy? A systematic review of randomized trials.

OBJECTIVE: To systematically evaluate randomized controlled trials (RCTs), with at least 6 months of follow-up, on whether professional mechanical plaque removal (PMPR) including supragingival scaling should be performed prior and separately from subgingival scaling and root planning (SRP) in nonsurgical periodontal therapy (NSPT), in terms of clinical and patient-reported outcomes (PROs) (CRD42020219759). METHODS: The MEDLINE, EMBASE, CENTRAL, LILACS and Web of Science electronic databases, as well as grey literature sources, were searched by two independent reviewers up to May 2023. The Cochrane Collaboration's Risk of Bias tool (RoB 2.0) was used for quality appraisal and GRADE for assessing the certainty of evidence. Random-effects pairwise meta-analyses compared the changes in probing pocket depth (PPD), clinical attachment loss (CAL), and bleeding on probing (BoP) of a stepwise NSPT approach (PMPR prior and separately from SRP) and conventional one-step NSPT through mean differences (MDs) and associated confidence intervals (95% CI). RESULTS: Two RCTs were included, including data of 77 participants with severe periodontitis. One RCT presents high risk of bias and the other has some concerns. No significant differences were found between the stepwise approach and performing both steps simultaneously for any clinical outcomes, with overall very low certainty on evidence. No adverse effects were detected and there was no data on PROs. CONCLUSIONS: There is very-low certainty evidence of no significant difference on PPD and BoP reductions and CAL gain between supragingival scaling performed prior and separately from SRP and conventional one-step NSPT.

The Effects of Periodontal Treatment on Rheumatoid Arthritis and of Anti-Rheumatic Drugs on Periodontitis: A Systematic Review.

Rheumatoid arthritis (RA) and periodontitis are chronic inflammatory diseases that widely spread and share the same patterns of pro-inflammatory cytokines. This systematic review aims to evaluate the effects of non-surgical periodontal treatment (NSPT) on RA and, conversely, the impact of disease-modifying anti-rheumatic drugs (DMARDs) on periodontitis. PubMed, Embase, and Web of Science were searched using the MESH terms "periodontitis" and "rheumatoid arthritis" from January 2012 to September 2023. A total of 49 articles was included in the final analysis, 10 of which were randomized controlled trials. A total of 31 records concerns the effect of NSPT on parameters of RA disease activity, including a 28-joint disease activity score, anti-citrullinated protein antibodies, rheumatoid factor, C reactive protein, erythrocyte sedimentation rate, pro-inflammatory cytokines and acute phase proteins in serum, saliva, gingival crevicular fluid, and synovial fluid. A total of 18 articles investigated the effect of DMARDs on periodontal indexes and on specific cytokine levels. A quality assessment and risk-of-bias of the studies were also performed. Despite some conflicting results, there is evidence that RA patients and periodontitis patients benefit from NSPT and DMARDs, respectively. The limitations of the studies examined are the small samples and the short follow-up (usually 6 months). Further research is mandatory to evaluate if screening and treatment of periodontitis should be performed systematically in RA patients, and if the administration of DMARDs is useful in reducing the production of cytokines in the periodontium.

Azithromycin with scaling and root planing versus scaling and root planing alone in the treatment of periodontitis: A randomized controlled trial.

Background: The growing interest in the possibilities of macrophages modulation with therapeutic purposes promotes new approaches for periodontitis treatment. Aim: The aim of this randomized controlled open clinical study was to evaluate the early clinical and immunological effects of the long-course azithromycin as an adjunct to scaling and root planing in periodontitis. Methods: 50 patients (with stage I-III, grade A/B periodontitis) and 22 periodontally healthy volunteers as the reference group were recruited. Following scaling and root planing (SRP), the patients were randomly assigned to one of two treatment modalities: SRP only (n = 25) and adjunct azithromycin (Az) treatment (n = 25). The patients were monitored at baseline, and 30 ± 5 days after therapy. Clinical attachment loss (CAL), periodontal probing depth (PPD) and bleeding on probing (BoP) were evaluated. Secondary outcome measures included mean changes in single-positive CD68 + and CD163 + macrophages (Mφs) density and ratio, evaluated by immunohistochemistry, and IL1-ß, IL-6, IL-10, TGF-ß levels, detected by ELISA. Results: At 1 month both groups showed significant improvements of CAL, PPD and BoP, without significant added benefit in terms of CAL, PPD and BoP of Az. But Az increased the density of CD68 + and CD163 + Mφs (P < 0.0001), decreased the CD68+/CD163 + ratio (P = 0.043), decreased IL-1ß (P < 0.01), IL-6 (P < 0.001) levels, and increased IL-10 (P < 0.0001) and TGF-ß (P < 0.001) levels compared to SRP and periodontitis at baseline. Conclusion: The long course of Az demonstrated modulation of CD68 + and CD163 + Mφs towards M2 polarization, which may play a significant role in achieving favorable long-term treatment outcomes.

EVIDENCE SUPPORTS SHORT-TERM CLINICAL BENEFITS OF ADJUNCTIVE ORAL PROBIOTICS FOLLOWING SCALING AND ROOT PLANING TREATMENT.

ARTICLE TITLE AND BIBLIOGRAPHIC INFORMATION: Hu D, Zhong T, Dai Q. Clinical efficacy of probiotics as an adjunctive therapy to scaling and root planning in the management of periodontitis: a systematic review and meta-analysis of randomized controlled trails. J Evid Based Dent Pract. 2021;21(2):101547. doi:10.1016/j.jebdp.2021.101547. SOURCE OF FUNDING: Self-funded. TYPE OF STUDY/DESIGN: Systematic review with meta-analysis of data.

Role of Bisphosphonates in Periodontal Diseases: Systematic Review.

Introduction: The chief aim in managing periodontal diseases is the elimination of causative factors that may vary from pathogens to physical parameters. In the current systematic review, the effectiveness of "Bisphosphonate Therapy" as a supplement to "Scaling and Root Planing (SRP)" in the management of periodontitis is calibrated from the previous studies. Materials and Methods: An extensive online search in the various databanks of EMBASE, Medline, Pubmed, and Scopus was conducted. The keywords searched were "Probing depth (PD)" which was the main endpoint, and variations in "Clinical Attachment Level (CAL)" and/or "Bone Defect (BD) fill" were the secondary variants that were searched for in the current study. The data collected were tabulated and compared using the means and the standard deviations. Using the random effect method the mean variations and the confidence intervals (95%) of the parameters were assessed. Results: Eight studies were finalized. Alendronate was utilized as a supplement to SRP in seven studies, four of which employed topical administration and three of which used oral alendronate. A substantial grade of heterogeneity for Probing depth (P < 0.0001), Clinical Attachment Level (P = 0.007), and Bone Defect fill (P < 0.0001) was observed amongst groups when comparing the properties of adjunctive BT to SRP alone. In comparison to SRP alone, SRP with bisphosphonate treatment significantly reduced PD (P = 0.002), increased CAL (P = 0.008), and filled BD (P < 0.001). Conclusions: Although BT as an adjunct appears to be successful in treating periodontitis, its practical applicability is questionable due to the possibility of developing jaw osteonecrosis and the short-range follow-up of the research.

Salivary Soluble CD44 Level in Chronic Periodontitis - A Comparative Assessment between Preoperative and Postoperative Scaling and Root Planing.

Background: Salivary biomarkers can be used to diagnose illnesses, track their course, and gauge a patient's response to therapy. Inflammatory circumstances result in higher sCD44 levels. The most typical inflammatory disorder connected to periodontal tissue is called periodontitis. Therefore, the purpose "of the current study was to compare the levels of sCD44 in patients with chronic periodontitis before and after scaling and root planing. Objectives: 1) Determining CD44 concentrations in healthy individuals' spit. 2) To quantify CD44 levels in the saliva of individuals with persistent periodontitis. The third objective is to compare the levels of CD44 that can be dissolved in saliva between those with healthy gums and those with active periodontitis. 4) Assessing CD44 levels in saliva after "scaling and root planing in patients with chronic periodontitis." Materials and Methods: Half of the study participants were classified as having chronic periodontitis, while the other half had healthy gums. Participants with healthy gums and those with chronic periodontitis had their plaque levels, gingival status, and testing depths measured. All the same, data were calculated in persons with chronic periodontitis one month after they had "scaling and root planing done. Clinical attachment levels were evaluated before scaling and root planing was performed on patients with chronic periodontitis and again one month afterwards. Patients with chronic periodontitis," those whose condition had not improved following scaling and root planing (SRP), and healthy individuals all had spit tests conducted after a month. The concentration of sCD44 in the saliva was determined with a chemically coupled immunosorbent assay. Results: Salivary sCD44 levels were substantially greater in people with chronic periodontitis than in people without the condition. After one month of scaling and root planing in patients with chronic periodontitis, sCD44 levels drastically dropped (p < 0.0001). Conclusion: Chronic periodontitis is linked to elevated levels of salivary sCD44. sCD44 can be employed as a possible salivary biomarker for chronic Periodontitis.

Microbiological and Clinical Evaluation of Efficacy of Locally Delivered Tetracycline in Conjunction with Scaling and Root Planning.

Introduction: Chronic periodontitis is an infectious disease which is multifactorial in etiology. The red complex bacteria have an enzyme capable of hydrolyzing the synthetic trypsin substrate, N-benzoyl-DL-arginine-2-napthylamide (BANA). Tetracycline as a bacteriostatic agent is used in the treatment of periodontitis. Objective: The aim of this study was to evaluate clinically and microbiologically the efficacy of tetracycline fibers in conjunction with scaling and root planning in chronic periodontitis patients. Methodology: A Split mouth clinical and microbiological randomized control study was done to compare the clinical effects of subgingivally delivered antimicrobial bioabsorbable controlled release 2 mg tetracycline fibers as an adjunct to scaling and root planning on one side and comparing the other side treated only with scaling and root planning only. Result: Showed both scaling and root planning and the use of tetracycline an adjunct with scaling and root planning are equally effective. Conclusion: It can be concluded that Scaling and root planing (SRP) with or without use of adjunct local drug delivery agent like tetracycline is effective in treating chronic periodontitis.

The "double-edged" role of progesterone in periodontitis among perimenopausal women undergoing or not undergoing scaling and root planing.

Objective: Progesterone (PG) is an important sex steroid hormone commonly administered to protect the endometrium in perimenopausal women. The present study aimed to explore differential responses of periodontitis to PG in perimenopausal women who did or did not undergo scaling and root planing (SRP). Methods: A total of 129 perimenopausal women with mild-to-moderate periodontitis were enrolled and underwent treatment as follows: SRP (n = 35); SRP + PG (n = 34); PG (n = 31); and no treatment (s) (n = 29). Pocket probing depth (PPD), clinical attachment level (CAL), sulcus bleeding index (SBI), and bleeding on probing (BOP) were measured using periodontal probes. Three inflammatory markers, including C-reactive protein (CRP), interleukin (IL)-6, and tumor necrosis factor-alpha (TNF-α) in gingival crevicular fluid (GCF) were measured using ELISA techniques. Results: PPD, CAL, SBI, BOP, and levels of inflammatory factors in GCF were all significantly decreased in perimenopausal women with periodontitis after SRP. In patients who did not undergo SRP, 6 months of PG treatment significantly elevated PPD, SBI, BOP, and GCF levels of CRP, IL-6, and TNF-α. In contrast, PG exhibited inhibitory effects on periodontal inflammation in patients who underwent SRP, evidenced by significantly decreased BOP and IL-6, and slightly decreased SBI, CRP, and TNF-α. PG-induced changes dissipated 6 months after withdrawal of PG (at 12 months). Conclusions: Among perimenopausal women with periodontitis, PG enhanced periodontal inflammation in the absence of SRP but inhibited periodontal inflammation in those who underwent SRP.

Changes in the level of cytokines in the saliva of hypertensive patients with chronic periodontitis after scaling and root planning.

INTRODUCTION: Cytokines have a key role in the pathogenesis of both hypertension and periodontitis. Salivary diagnosis is a promising field with numerous clinical applications. Since limited studies have been carried out on how salivary inflammatory cytokines can be determined and how well periodontal disease and hypertension might react to scaling and root planning (SRP). The goal of this study was to identify the pattern of changes in salivary inflammatory cytokines in chronic periodontitis subjects with hypertension after nonsurgical periodontal therapy. METHODS: It included observational trial recruited 94 chronic periodontitis patients, 44 of whom had hypertension. All subjects have undergone non- surgical periodontal treatment. The clinical periodontal parameters included gingival index (GI), plaque index (PI), and probing of pocket depth (PPD). Unstimulated saliva was collected to determine the inflammatory biomarkers (using a commercial Elisa kit) both before and after SRP RESULTS: In comparison to non-hypertensive participants, the periodontal PPD was significantly higher in hypertensive subjects. All clinical parameters in the first examination, except for PI, were significantly higher in hypertensive than in non-hypertensive subjects. Plaque Index, GI, and PPD parameters at first visit and after finishing treatment positively correlated with salivary IL-1ß, excluding pretreatment GI. The current results demonstrate the presence of a positive correlation between diastolic blood pressure and TNF (r = 0.330 and P = 0.029). All patients enrolled in this study showed a significant increase in the salivary levels of IL-4 after SRP. CONCLUSIONS: The current study offer important and valuable information concerning the practical application of pro-inflammatory and anti-inflammatory cytokines as useful biomarkers and indicators for determining the outcome of SRP and progression of chronic periodontitis in patients with hypertension.

Association of vitamin D in individuals with periodontitis: an updated systematic review and meta-analysis.

BACKGROUND: There are differences in vitamin D levels between periodontitis and healthy individuals, but the effect of vitamin D on periodontitis is controversial. The purpose of this Meta-analysis is twofold: (1) compare vitamin D levels in individuals with or without periodontitis; (2) assess the effects of vitamin D supplementation during scaling and root planing (SRP) on periodontal clinical parameters in individuals with periodontitis. METHODS: A systematic search was conducted in five databases (PubMed, Web of Science, MEDLINE, EMBASE, and Cochrane library), published from the database inception to 12 September 2022. The Cochrane Collaboration Risk of bias (ROB) assessment tool, the risk of bias in non-randomized studies of intervention (ROBINS-I) tool, the Newcastle-Ottawa Quality Assessment Scale (NOS), and Agency for Healthcare Quality and Research (AHRQ) were used to evaluate randomized controlled trial (RCT), non-RCT, case-control study, and cross-sectional study, respectively. Statistical analysis was performed using RevMan 5.3 and Stata 14.0 software, with weighted mean difference (WMD), standardized mean difference (SMD) and 95% confidence intervals (CI) as the effect measures, and heterogeneity was tested by subgroup analysis, sensitivity analysis, Meta-regression. RESULTS: A total of 16 articles were included. The results of Meta-analysis showed that periodontitis was associated with lower serum vitamin D levels compared to normal population (SMD = -0.88, 95%CI -1.75 ~ -0.01, P = 0.048), while there was no significant difference in serum or saliva 25(OH)D levels between periodontitis and normal population. Additionally, the Meta-analysis showed that SRP + vitamin D and SRP alone had a statistically significant effect on serum vitamin D levels in individuals with periodontitis (SMD = 23.67, 95%CI 8.05 ~ 32.29, P = 0.003; SMD = 1.57, 95%CI 1.08 ~ 2.06, P < 0.01). And SRP + vitamin D could significantly reduce clinical attachment level compared to SRP alone (WMD = -0.13, 95%CI -0.19 ~ -0.06, P < 0.01), but had no meaningful effect on probing depth, gingival index, bleeding index, respectively. CONCLUSION: The evidence from this Meta-analysis suggests that the serum vitamin D concentration of individuals with periodontitis is lower than that of normal people, and SRP along with vitamin D supplementation has been shown to play a significant role in improving periodontal clinical parameters. Therefore, vitamin D supplementation as an adjuvant to nonsurgical periodontal therapy has a positive impact on the prevention and treatment of periodontal disease in clinical practice.

Micro-CT evaluation of the effect of various ScRp instrumentation methods on cement loss, porosity and micro-crack formation.

OBJECTIVES: The purpose of this study was to compare the effectiveness of three different instruments on cement loss, porosity and micro-crack formation, which was not evaluated before, following scaling and root planning (SRP) using micro-computed tomography (micro-CT). METHODS: In this experimental study, 30 single-rooted extracted human teeth were used and divided into three groups. All the teeth were scanned with micro-CT before and after SRP. Group 1: SRP was performed with Gracey curettes, Group 2: SRP was performed by using an ultrasonic device, and Group 3: SRP was performed by using diamond burs. Cement loss from the root surface, porosity, and micro-crack formation in the root dentine were analysed. Micro-CT is used for qualitative and quantitative analysis of samples. The obtained data were analysed statistically (p < 0.05). RESULTS: Minimum cement loss following SRP was detected with ultrasonic scaler (26.98 mm3 ), whereas the highest was created by diamond burs (96.20 mm3 ) (p < 0.05). The total porosity values after SRP were 0.278%, 0.334% and 0.252% for Groups 1, 2 and 3, respectively. Although Group 3 had the least porosity values, there was no statistically significant difference between the groups. The highest micro-crack formation was seen in Group 2 and the lowest was in Group 1 with a significant difference (p < 0.05). CONCLUSIONS: More cement loss was observed with diamond burs. Ultrasonic devices appear to be a viable alternative to instrumentation with curettes. However, ultrasonic devices should be used carefully because of micro-crack formation since the micro-crack resulting from instrumentation with hand instruments is the least of all.

Benefits of Antimicrobial Photodynamic Therapy as an Adjunct to Non-Surgical Periodontal Treatment in Smokers with Periodontitis: A Systematic Review and Meta-Analysis.

The objective of this study was to analyze evidence of the clinical and microbiological benefits of antimicrobial photodynamic therapy (aPDT) adjunctive to scaling and root planing (SRP) in smokers with periodontitis. Randomized clinical trials (RCTs) were included, through an electronic search in PubMed/MEDLINE, LILACS, Web of Science, and the Cochrane Library for articles published in English until December 2022. The quality of the studies was assessed using the JADAD scale and the risk of bias was estimated using the Cochrane Collaboration assessment tool. Of the 175 relevant articles, eight RCTs were included. Of these, seven reported clinical results and five microbiological results, with a follow-up time of 3-6 months. A meta-analysis was performed for the probing depth (PD) reduction and clinical attachment level (CAL) gain at 3 and 6 months. The weighted mean differences (WMDs) and 95% confidence intervals (CIs) were counted for the PD and CAL. The overall effect for the PD reduction at 3 and 6 months (WMD = -0.80, 95% CI = -1.44 to -0.17, p = 0.01; WMD = -1.35, 95% CI = -2.23 to -0.46, p = 0.003) was in favor of aPDT. The CAL gain (WMD = 0.79, 95% CI = -1.24 to -0.35, p = 0.0005) was statistically significant at 6 months, in favor of aPDT. In these RCTs, aPDT was unable to demonstrate efficacy in reducing the microbial species associated with periodontitis. aPDT as an adjuvant to SRP improves the PD reduction and CAL gain more effectively than only SRP. RCTs are needed to establish standardized protocols with longer follow-up times in order to provide more results on aPDT adjunctive to SRP in smokers with periodontitis.

Minimally invasive non-surgical therapy (MINST) in stage III periodontitis patients: 6-month results of a split-mouth, randomised controlled clinical trial.

OBJECTIVES: To determine if minimally invasive non-surgical therapy (MINST) outperforms classical non-surgical periodontal therapy for stage III periodontitis with primarily suprabony (horizontal) type defects. MATERIALS AND METHODS: In a split-mouth randomised controlled trial, 20 patients' dental quadrants were randomly assigned to MINST or classical non-surgical treatment. The primary outcome variable was the number of sites with probing pocket depth ≥ 5 mm and BOP. Treatment method, tooth type, smoking status, and gender were evaluated using a multivariate multilevel logistic regression model. RESULTS: After 6 months, the percentage of sites with PD ≥ 5 mm and BOP that healed (MINST = 75.5%; control group = 74.1%; p = 0.98), and the median number of persisting sites (MINST: 6.5, control group: 7.0; p = 0.925) were similar in both groups. In the test and control groups, respectively, median probing pocket depths (2.0 mm vs. 2.1 mm) and clinical attachment level (1.7 mm vs. 2.0 mm) changed significantly (p < 0.05) but similarly. Significantly less gingival recession occurred in the MINST group's deep molar pockets compared to the control group (p = 0.037). Men (OR = 0.52, p = 0.014) and non-molars (OR = 3.84, p 0.001) had altered odds for healing of sites with PD ≥ 5 mm and BOP. CONCLUSIONS: MINST reduces gingival recession associated with molar teeth, although it performs similarly to traditional non-surgical therapy in treating stage III periodontitis with predominately horizontal-type defects. CLINICAL RELEVANCE: MINST performs similarly to non-surgical periodontal therapy in stage III periodontitis with predominantly suprabony defects.

Probiotic adjuvant treatment in combination with scaling and root planing in chronic periodontitis: a systematic review and meta-analysis.

This systematic review and meta-analysis assessed the impact of probiotic supplementation on treating chronic periodontal (CP) disease based on clinical and microbiological findings. Four databases were searched: Medline, Embase, Cochrane Library, and the Web of Science databases. The references to relevant studies were also manually searched. Analyses were conducted using the Review Manager 5.2 software, while the quality of randomised controlled trials was assessed with the Cochrane Risk of Bias tool. In total, 19 studies were included in the meta-analysis. Pooled results revealed that the adjuvant use of probiotics in the treatment of patients with periodontal disease was largely associated with good clinical efficacy. Resulting in statistically significant improvements in plaque index (P<0.05), periodontal probing depth (P<0.05), clinical attachment level (P<0.05), gingival index (P<0.05), bleeding on probing (P<0.05), deep probing depth (P<0.05), and levels of subgingival microbes (P<0.05) following probiotic supplementation. In summary, the results of this meta-analysis suggest that the administration of probiotics together with scaling and root planing can somewhat improve CP patient clinical outcomes and reduce levels of periodontal pathogens. However, more comprehensive experiments are needed to standardise probiotics and maximise their adjuvant therapy.

The effects of adjunctive use of a desiccant agent in the treatment of stage III periodontitis (Randomized controlled clinical trial).

Introduction: Several bacterial species inhabiting the dental plaque biofilms are associated with periodontitis. Objective: The main objective of this study was to compare the efficacy of the desiccant agent HYBENX (HBX) as an adjunct to scaling and root planning (SRPX) versus scaling and root planning (SRP) alone in the treatment of periodontitis. Materials and Methods: The study sample comprised 25 patients with periodontitis stage Ш (grades A and B). Each maxillary quadrant was randomly allocated to two groups: SRPX group, including 25 quadrants treated with SRP plus HYBENX, and SRP group, including 25 quadrants treated with SRP alone. The following clinical periodontal parameters were recorded at baseline (immediately after treatment, T0), and 1 month (T1), 3 months (T3), and 6 months (T6) after treatment: probing pocket depth (PPD), relative attachment level (RAL), plaque index (PLI), gingival index (GI), gingival height (GH), and bleeding on probing index (BOP). Results: Comparisons within each study group showed that all clinical parameters significantly improved (P < 0.001) at all follow-up intervals. In contrast, a statistically significant difference (P < 0.001) was observed in RAL, PPD, BOP, and GI indices at all follow-up intervals between the SRPX and SRP groups. In contrast, no significant differences (P > 0.05) were found in GH and PLI between the study groups. Conclusion: Both treatment groups showed improved periodontal parameters. However, applying desiccant gel as an adjunct to SRP was significantly effective in the treatment of stage III periodontitis.

Efficacy of a Revised Prototype Solution to Facilitate the Removal of Dental Calculus: A follow-up proof-of-concept study.

Purpose The purpose of this follow-up proof-of-concept study was to determine the efficacy of a revised calculus disruption solution in facilitating the removal of both supragingival and subgingival calculus in-vivo, as measured by time, difficulty, and pressure required to remove supragingival and subgingival calculus.Methods Patients from a dental school in Minnesota were recruited to participate in a randomized, split-mouth, cross sectional proof-of-concept study comparing time, difficulty and pressure used with hand instrumentation alone compared to the use of a calculus disruption solution and hand instrumentation. Quadrants were randomized to either treatment or control group. Descriptive and inferential statistics were used to analyze the amount of time used. A paired Student's t-test was used to analyze the primary outcome (α = 0.05). Post-treatment questionnaires were completed by the investigator and participants to score the perceived difficulty and pressure required to remove calculus.Results Thirty participants completed the study. An average of 3.1 minutes less time was needed to remove supra and subgingival calculus in the treatment quadrants although this was not statistically significant (p=0.5757). The secondary outcomes, the investigator and participants' perceived difficulty and pressure used for calculus removal showed either no difference, or slight improvements in the treatment quadrants. Overall, the product was well tolerated by participants.Conclusion Quadrants treated with a calculus disruption solution, required slightly less time than control quadrants for calculus removal with hand instruments although the difference was not statistically significant. Reformulation to increase the viscosity of the solution may improve efficacy. Future studies should include a larger sample size, using multiple operators, and a double-blind study design.

Efficacy of intraseptal anesthesia obtained by computer-controlled articaine with epinephrine delivery in scaling and root planing.

OBJECTIVES: The primary aim of this study was to compare the anesthetic efficacy of the intraseptal anesthesia (ISA) obtained with three doses of 4% articaine with 1:100,000 epinephrine (4%Ar + Ep) for scaling and root planing (SRP), using a computer-controlled local anesthetic delivery system (CCLADS). The secondary aims were to compare the clinical anesthetic parameters in relation to different jaw regions and examine the possible influence of sex and smoking habits on them. MATERIALS AND METHODS: SRP under ISA obtained with different doses (0.1 ml, 0.2 ml, and 0.3 ml) of 4%Ar + Ep was performed in 360 patients. The success rate, onset, duration of soft tissue anesthesia, and the anesthetic field widths were recorded by pinprick testing. RESULTS: The anesthesia success was high (90-95%). The onset was immediate. The duration and anesthetic field widths showed a dose-related significance, however, without a consistent sex-related or smoking-related significance. The multiple logistic regression analysis revealed a twofold higher chance of anesthesia success by increasing the dose and increased bleeding on probing-related and female sex-reduced probability of anesthesia success. CONCLUSIONS: ISA obtained with 0.3 ml of 4%Ar + Ep delivered by a computer-controlled local anesthetic delivery system provided a high anesthetic success and the adequate clinical anesthetic parameters for SRP in all regions of both jaws. CLINICAL RELEVANCE: ISA obtained with 4%Ar + Ep provides an effective anesthesia for SRP. The anesthetic success rate may be reduced in the presence of gingival inflammation and in females as well. The study was registered in a Clinical Trials database (NCT04392804, registration date May 9, 2020).

The effect of antibiotics on the periodontal treatment of diabetic patients with periodontitis: A systematic review and meta-analysis.

Background: The aim of this meta-analysis was to compare the effects of periodontal treatment with or without adjunctive antibiotic on periodontal status and blood glucose level in diabetic patients with periodontitis. Methods: A search using electronic database (MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials) and a manual search were performed up to July 2022. Eligible 13 RCTs were included according to inclusion and exclusion criteria. Reviewers independently performed data screening, data selection, data extraction, and risk of bias. Quality assessment was performed according to the Cochrane Handbook for Systematic Reviews of Interventions. Weighted mean differences and 95% confidence intervals (CIs) for continuous outcomes were calculated using random or fixed-effects models. This review is registered in the PROSPERO database (CRD42022347803). Results: Of the 13 included articles, eight were on the use of systemic antibiotics and five on topical antibiotics. The results showed statistically significant improvement in periodontal status (probing depth, clinical attachment loss and bleeding on probing) at 6 months with systematic antibiotics use (PD-6M p = 0.04, BOP-6M p < 0.0001, CAL-6M p = 0.002). The improvement in PD with topical antibiotics was statistically significant at 1 month (p = 0.0006). However, there was no statistically significant improvement in periodontal status at 3 months with adjuvant systemic antibiotics. Conclusion: Antibiotics can improve the periodontal condition of diabetic patients with periodontitis to a certain extent. In clinical practice, it is necessary to comprehensively consider the balance of benefits and risks before deciding whether to use antibiotics.
