Short-term and long-term effectiveness of powered toothbrushes in promoting periodontal health during orthodontic treatment: A systematic review and meta-analysis

Evaluation of dental plaque reduction using microcurrent-emitting toothbrushes in orthodontic patients: a randomized, double-blind, crossover clinical trial

This study aimed to compare the effectiveness of microcurrent-emitting toothbrushes (MCTs) and ordinary toothbrushes in reducing the dental plaque index (PI) and dental caries activity among orthodontic patients. The evaluation was performed using a crossover study design involving 22 orthodontic patients randomly assigned to the MCT or ordinary toothbrush groups. The participants used the designated toothbrush for 4 weeks and had a 1-week wash-out time before crossover to the other toothbrush. PI (Attin's index) and dental caries activity were measured at baseline and at the end of each 4-week period. Additionally, patients completed questionnaires to assess patient satisfaction for "freshness in mouth" and "cleansing degree." The results showed that the MCT group had a significant reduction in PI (p = 0.009), whereas the ordinary toothbrush group did not (p = 0.595). There was no significant difference in the dental caries activity between the two groups (p > 0.05). Patient satisfaction assessment revealed that 65% patients in the MCT group had more than "fair" experience of freshness, in contrast to 50% of patients in the ordinary toothbrush group. Satisfaction with cleansing degree was similar in both groups. Overall, these findings suggest that MCTs are more effective in reducing dental PI than ordinary toothbrushes.

Effects of chlorhexidine use on periodontal health during fixed appliance orthodontic treatment: a systematic review and meta-analysis

BACKGROUND

Proper oral hygiene and absence of periodontal inflammation is pre-requisite for orthodontic treatment. Chlorhexidine (CHX) is an established oral antiseptic used in the treatment of periodontal disease, but its role in orthodontic therapy is unclear.

OBJECTIVES

To assess the efficacy of adjunct use of CHX-containing products in maintaining gingival health among orthodontic patients with fixed appliances.

SEARCH METHODS

Five databases were searched without limitations up to August 2021.

SELECTION CRITERIA

Randomized clinical trials (RCTs) assessing Gingival Index (GI) (primary outcome), Plaque Index (PI), Bleeding Index (BI), or Pocket Probing Depth (PPD).

DATA COLLECTION AND ANALYSIS

Study selection, data extraction, and risk of bias assessment were done independently in duplicate. Random-effects meta-analyses of mean differences (MDs) or standardized mean differences (SMDs) with their 95% confidence intervals (CIs) were conducted, followed by sensitivity and Grades of Recommendations, Assessment, Development and Evaluation analysis.

RESULTS

Twenty RCTs (1001 patients) were included assessing CHX-containing mouthwashes (n = 11), toothpastes (n = 2), gels (n = 3), or varnishes (n = 4) compared to placebo/control (n = 19) or sodium fluoride-products (n = 4). In the short-term, CHX-containing mouthwash was associated with lower GI (n = 9; MD = -0.68; 95% CI = -0.97 to -0.38; P < 0.001; high quality), lower PI (n = 9; MD = -0.65; 95% CI = -0.86 to -0.43; P < 0.001; high quality), lower BI (n = 2; SMD = -1.61; 95% CI = -2.99 to -0.22; P = 0.02; low quality), and lower PPD (n = 2; MD = -0.60 mm; 95% CI = -1.06 to -0.14 mm; P = 0.01; low quality). No considerable benefits were found from the use of CHX-gel or CHX-varnish in terms of GI, PI, or PPD (P > 0.05/low quality in all instances). Use of a CHX-containing toothpaste was more effective in lowering PI (Heintze-index) than adjunct use of fluoride-containing mouthwash (n = 2; MD = -5.24; 95% CI = -10.46 to -0.02; P = 0.04), but not GI (P = 0.68) or BI (P = 0.27), while sensitivity analyses indicated robustness.

CONCLUSIONS

Adjunct use of CHX mouthwash during fixed-appliance treatment is associated with improved gingival inflammation, plaque control, and pocket depths, but caution is warranted and recommendations about CHX use during orthodontic treatment of children/adults should consider the heterogeneous patient response, cost-effectiveness, and potential adverse effects.

Effectiveness of Tooth Brushes on Gingival Health in Patients undergoing Orthodontic Treatment

Aim: To evaluate and compare the effectiveness of two different manual toothbrushes on gingival health among patients undergoing orthodontic treatment. Methodology: In the present randomized cross-over controlled trial, 60 subjects were recruited, to receive either crisscross or multilevel bristle design. Modified Gingival Index (MGI), Modified Silness and Loe Plaque Index, and Gingival Bleeding Index (GBI) and were assessed for 120 days. Statistical analysis was done using SPSS version 21 (SPSS; Chicago, IL, USA). Owing to the ordinal nature of the indices, non-parametric tests of significance were used. Results: The efficacy of the two-bristle design brush showed an overall reduction in the mean score. Overall significant differences were seen in the efficacy of the two different bristle designs. Both the study groups showed a reduction in the mean MGI, PL, and GBI with a P value less than 0.001 which was statistically significant. Conclusion: In the present study, the criss-cross bristle design was found to be significantly more effective as compared to the multilevel toothbrush design for reducing MGI, PL, and GBI scores.      

Periodontal Management in Periodontally Healthy Orthodontic Patients with Fixed Appliances: An Umbrella Review of Self-Care Instructions and Evidence-Based Recommendations

The present umbrella review aimed to characterize periodontal self-care instructions, prescriptions, and motivational methods; evaluate the associated periodontal outcomes; and provide integrated, evidence-based recommendations for periodontal self-care in periodontally healthy orthodontic patients with fixed appliances. The presently applied study protocol was developed in advance, compliant with the PRISMA statement, and registered on PROSPERO (CRD42022367204). Systematic reviews published in English without date restrictions were electronically searched until 21 November 2022 across the PROSPERO Register and Cochrane Library, Web of Science (Core Collection), Scopus, and MED-LINE/PubMed databases. The study quality assessment was conducted through the AMSTAR 2 tool. Seventeen systematic reviews were included. Powered and manual toothbrushes showed no significant differences in biofilm accumulation, although some evidence revealed significant improvements in inflammatory, bleeding, and periodontal pocket depth values in the short term with powered toothbrushes. Chlorhexidine mouthwashes, but no gels, varnishes, or pastes, controlled better biofilm accumulation and gingival inflammation as adjuncts to toothbrushing, although only for a limited period. Organic products, such as aloe vera and chamomile, proved their antimicrobial properties, and herbal-based mouthwashes seemed comparable to CHX without its side effects. Motivational methods also showed beneficial effects on periodontal biofilm control and inflammation, while no evidence supported probiotics administration.

COVID-19 Related Information on Pediatric Dental Care including the Use of Teledentistry: A Narrative Review

In addition to the direct impact of the SARS-CoV-2 infection, the COVID-19 pandemic reports multiple effects on people's health and psycho-physical well-being. In the dental field, oral hygiene sessions, regular dental check-ups, and aerosol-generating procedures were commonly postponed, thus resulting in repercussions on oral health also favored by the changing eating and oral hygiene habits during the multiple lockdowns. Furthermore, dental settings and practices were generally perceived as at high risk for SARS-CoV-2 transmission, thus unsafe, and by general and pediatric dentists themselves. Last, the consequences of stress related to deprivation of social life and playful activities should not be underestimated in children, exposing them to the deleterious effects of bad oral habits, with repercussions on the balanced growth and development of the stomatognathic system. The present work intends to analyze the medium-term and long-term impact of COVID-19 on pediatric oral and dental care provision, reviewing pediatric dentistry practice and oral and dental needs of pedodontics patients during the first peak and the various waves of the COVID-19 pandemic, and lessons learned.

Management of white spot lesions induced during orthodontic treatment with multibracket appliance: a national-based survey

OBJECTIVES

The study aimed to survey current strategies against enamel demineralization during multibracket therapy (MBT) and guide a prevention concept based on existing scientific evidence.

MATERIALS AND METHODS

The survey comprised questions on the prevention and management of white spot lesions (WSL). The questionnaire was sent via email to orthodontists working in practices and universities throughout Germany. The analysis involved descriptive statistics using the chi-square test (p < 0.05).

RESULTS

A prevention protocol was used before MBT by 80.6% of the participants. Less than a quarter of the participants regularly applied topical fluoride (gel or varnish) during MBT. According to the respondents' assessment, the prevalence of WSL during MBT is 11.6%, mainly observed in 12- to 15-year-old male patients. Orthodontists graduating after 2000 tended to recommend and apply fluoride-containing materials more often than their senior colleagues (p = 0.039). Participants from private practices applied fluoride varnish or gel more frequently than those from university clinics (p = 0.013). Fluoridation was the most common (70.7%) treatment for WSL after MBT, followed by resin infiltration (21.2%). The majority (80.9%) of the participants favor a guideline for preventing WSL.

CONCLUSIONS

WSL prevention during MBT is challenging. Males in puberty are predominantly affected. Younger orthodontists are more concerned about the prevention of WSL during MBT.

CLINICAL RELEVANCE

The non-negligible prevalence of individuals with WSL emphasizes the need for dental education and health care reform. This would help to implement standardized procedures and establish innovative applications.

Prevention of demineralization during multi-bracketed fixed orthodontic treatment: An overview of systematic reviews

BACKGROUND

Demineralization during multi-bracketed fixed orthodontic treatment is a well-known problem.

AIM

To systematically evaluate the evidence for the prevention of enamel demineralization during multi-bracketed fixed orthodontic treatment.

DESIGN

Systematic reviews (with or without meta-analysis) that have appraised the primary studies on the prevention of demineralization during multi-bracketed fixed orthodontic treatment were searched systematically and included as per pre-defined eligibility criteria. The risk of bias of the included reviews was assessed by two authors using the ROBIS tool and AMSTAR-2 tool.

RESULTS

Twenty-nine reviews conducted on 128 exclusive primary studies were included for the present overview; 23 of these reviews were assessed to be of a high risk of overall bias, 5 were of low risk, and 1 review was of unclear risk of bias.

CONCLUSIONS

Predominantly, the published reviews have focused on fluorides, whereas some reviews have also studied the role of casein phosphopeptide-amorphous calcium phosphate (CPP-ACP), reminder therapy, lasers, and sealants. Professional fluorides, sealants, reminder therapy, and lasers might be valuable interventions to prevent demineralization during orthodontic treatment based on the conclusions of reviews with high quality; however, further studies are required to elucidate the role of CPP-ACP, chlorhexidine varnish, and powered toothbrushes.

A randomized, 3-month, parallel-group clinical trial to compare the efficacy of electric 3-dimensional toothbrushes vs manual toothbrushes in maintaining oral health in patients with fixed orthodontic appliances

INTRODUCTION

The aim of this single-blinded, parallel-group, randomized clinical trial was to compare the efficacy of electric 3-dimensional (3D) toothbrushes and manual toothbrushes in removing plaque and reducing gingival inflammation in orthodontic patients.

METHODS

Eighty adolescents with fixed orthodontic appliances in both arches were randomized at a 1:1 ratio, with an equal number of both sexes, in this examiner blinded, parallel clinical trial. Eligibility criteria included subjects aged between 12 and 16 years, good general health, nonextraction orthodontic treatment, and plaque-induced gingivitis, excluding patients with active caries or periodontitis, tooth agenesis, syndromes, disabilities, and craniofacial deformities, ≥2 cervical and/or proximal fillings, dental prostheses or dental implants, and subjects smoking or using antibiotics or medication predisposing to gingival enlargement. Patients were assigned to use either an electric 3D orthodontic toothbrush (Oral-B Pro-1000 with Oral-B Ortho head; Procter & Gamble, Cincinnati, Ohio) or a manual toothbrush (Oral-B Orthodontic brush; Procter & Gamble) and instructed to brush twice daily for 2 minutes. The main outcomes were: (1) plaque removal, assessed with the Modified Silness and Löe plaque index and the Modified Full Mouth Plaque Score, and (2) gingival inflammation reduction, assessed with the Modified Silness and Löe Gingival Index and the Modified Simplified Gingival Index. Measurements were taken at baseline, 1, 2, and 3 months. Randomization was achieved with 2 random sequences, one for each brush, written and sealed in opaque numbered envelopes. Blinding was possible for outcome assessment only.

RESULTS

Considerable variability was observed among patients in the values of all dependent variables. There was no difference between interventions over time for any of the outcomes, and the main effects for treatment and time were also not statistically significant. For Modified Silness and Löe plaque index, the interaction was 0.001 (95% confidence interval, -0.011 to 0.013; P = 0.89).

CONCLUSIONS

No difference in plaque removal efficacy and gingival inflammation reduction was found between the electric 3D and manual toothbrushes in adolescents with fixed orthodontic appliances. Therefore, orthodontists should focus on enhancing their patients' dental awareness and oral hygiene, along with professional prophylaxis and other oral hygiene aids, independently of the brush used.

REGISTRATION

This trial was registered at ClinicalTrials.gov (Identifier: NCT02699931).

PROTOCOL

The protocol was not published before trial commencement.

FUNDING

Electric and manual toothbrushes and toothpastes for all participants were provided by Procter & Gamble (Oral-B). Miscellaneous costs were covered by the participating departments.

The Effect of Removable Orthodontic Appliances on Oral Microbiota: A Systematic Review

Background (1): Removable orthodontic appliances may favor plaque accumulation and oral microbe colonization. This might be associated with intraoral adverse effects on enamel or periodontal tissues. The proposed systematic review was carried out to evaluate qualitatively and quantitatively the microbiological changes occurring during orthodontic therapy with removable orthodontic appliances. Methods (2): PubMed, Cochrane Library, Embase, Web of Science, Scopus, Ovid Medline, and Dentistry and Oral Sciences Source were searched. The research included every article published up to January 2020. The Preferred Reporting Items for Reporting Systematic reviews and Meta Analyses (PRISMA) protocol and the “Swedish Council on Technology Assessment in Health Care Criteria for Grading Assessed Studies” (SBU) method were adopted to conduct this systematic review. Results (3): The current study has a moderate evidence, demonstrating that removable appliances do influence the oral microbiota. Significant alterations occur just 15 days after the beginning of therapy, independently from the type of appliance. Furthermore, the levels of oral pathogens decrease significantly or even returned to pre-treatment levels several months later the therapy end. Conclusions (4): This review suggests that orthodontic treatment with removable appliances induces changes to oral microflora, but these alterations might not be permanent.

The short-term effects of manual and interactive powered toothbrushes on the periodontal status of orthodontic patients: A randomized clinical trial

OBJECTIVE

To compare the effects of manual and interactive powered toothbrushes on periodontal status of patients during fixed orthodontic treatment.

MATERIALS AND METHODS

Thirty-six patients aged 12 to 18 years were included in this parallel design randomized clinical trial. Patients were randomly divided into two groups: manual toothbrushes (MT group) and interactive powered toothbrushes (PT group). The plaque index (PI), gingival index (GI), and bleeding on probing (BOP) scores were obtained before brushing (T0), 4 weeks (T1), 2 months (T2), and 4 months (T3) after brushing initiation. Periodontal measurements were performed by the same researcher that blinded to the groups' randomization. Data were analyzed with Mann-Whitney U and Friedman tests for the comparison of parameters between groups and times.

RESULTS

Significant differences were found in PI values at all time intervals (P < 0.001), with one exception (T2-T3 in the MT group). The GI changes between timepoints were parallel to the BOP findings of the PT group. Both groups had significantly lower bleeding scores in both T0-T2 and T0-T3 time intervals (P < 0.001). There was a significant reduction in the bleeding score of PT group between T1-T3 time interval (P < 0.05); however, there were no significant differences between the groups at any timepoint. PI and GI scores were statistically decreased in the PT group compared with the MT group from baseline to 4 months (P < 0.05).

CONCLUSION

All periodontal parameters decreased during the 4-month study period. The interactive powered toothbrushes may be an alternative to manual toothbrushes in terms of maintenance of periodontal health during fixed orthodontic treatment.

Powered toothbrushes for plaque control in fixed orthodontic patients: a network meta-analysis

BACKGROUND

Orthodontic patients are at greater risk due to the inability to clean around the components directly bonded to teeth. Hence, the aim of the present network meta-analysis is to compare the utility of powered toothbrushes in plaque control in patients with orthodontic brackets compared with manual tooth brushing.

METHODOLOGY

Necessary data were extracted and analysed for Risk of Bias. Heterogeneity was assessed using Chi-square and I² tests. Random effects model was used for both direct and mixed treatment comparisons. Standardized mean difference with 95% confidence interval was the effect estimate for plaque and bleeding scores and mean difference for pocket depth. Inconsistencies between the direct and indirect estimates were evaluated by H-statistics. GRADE approach was used to assess the quality of evidence.

RESULTS

Pooled results from 14 studies showed significantly higher plaque scores in patients using manual toothbrushes. Pooled results from 13 studies showed significant higher bleeding scores as well with manual brushes. There was a significant reduction in pocket depth with electric toothbrushes.

CONCLUSION

Powered toothbrushes are a promising alternative for plaque control in patients with fixed orthodontic brackets. Stronger evidence can be established with addition of long-term clinical trials based on the recommendations.

Contemporary practices for mechanical oral hygiene to prevent periodontal disease

It is well established that dental plaque on teeth leads to gingivitis and periodontitis, and that several mechanical and chemical methods of plaque control can prevent gingivitis. The aim of the current review is to summarize and synthesize the available scientific evidence supporting practices for mechanical oral hygiene to prevent periodontal diseases. Evidence for contemporary practices of mechanical oral hygiene to prevent periodontal disease relies on studies of gingivitis patients. General recommendations concerning the ideal oral hygiene devices and procedures are still inconclusive. However, toothbrushing and interdental cleaning remain the mainstays of prevention of periodontal diseases. The primary approach requires individually tailored instruction for implementation of a systematic oral hygiene regimen.

Do probiotics promote oral health during orthodontic treatment with fixed appliances? A systematic review

BACKGROUND

Treatment with fixed orthodontic appliances has been associated with significant biofilm accumulation, thus putting patients at a higher risk of oral health deterioration. The use of probiotics has been proposed to be useful in the prevention or treatment of oral pathologies such as caries and diseases of periodontal tissues. Our aim was to investigate the effects of probiotic use on inflammation of the gingival tissues and the decalcification of the enamel in patients being treated with fixed orthodontic appliances.

METHODS

We searched without restrictions 8 databases and performed hand searching until September 2019. We searched for randomized controlled trials (RCTs) evaluating whether individuals with fixed orthodontic appliances benefit from probiotic treatment in terms of the inflammation of the gingivae and decalcification of the enamel. Following the selection of studies and the extraction of pertinent data, we appraised the risk of bias and the confidence in the observed effects based on established methodologies.

RESULTS

From the final qualifying studies, three did not show any statistically significant effect on gingival inflammation after probiotic administration of up to 1 month. Similarly, non-significant differences were noted in another study regarding white spot lesions development (mean administration for 17 months). No adverse effects were reported and the level of evidence was considered moderate.

CONCLUSIONS

Supplementation of orthodontic patients with probiotics did not affect the development of inflammation in the gingivae and decalcification in the enamel. Additional RCTs, with longer intervention and follow-up periods, and involving different combinations of probiotic strains are required.

Systematic reviews in orthodontics: Impact of the PRISMA for Abstracts checklist on completeness of reporting

INTRODUCTION

This study evaluated and compared the completeness of reporting of abstracts of orthodontics systematic reviews before and after the publication of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension for Abstracts Checklist (PRISMA-A).

METHODS

Abstracts of systematic reviews and meta-analyses in orthodontics published in PubMed, Latin American and Caribbean Health Sciences Literature, and the Cochrane Database of Systematic Reviews databases before March 23, 2018, that met the predefined inclusion and exclusion criteria, were evaluated using the 12 items of PRISMA-A, scoring each item from 0 to 2. Abstracts were classified into 2 groups: before and after publication of the PRISMA-A checklist. Three calibrated evaluators (intraclass correlation coefficient and kappa > 0.8) assessed the scores for compliance with the checklist. The number of authors, country of affiliation of the first author, performance of meta-analysis, and topic of the article were recorded. A regression analysis was performed to assess the associations between abstract characteristics and the PRISMA-A scores.

RESULTS

Of 1034 abstracts evaluated, 389 were included in the analysis. The mean PRISMA-A score was 53.39 (95% CI, 51.83-54.96). The overall score for studies published after the publication of the checklist was significantly higher than for studies published before (P ≤ 0.0001). The components returning significantly higher scores after publication of PRISMA-A were title (P = 0.024), information from databases (P = 0.026), risk of bias (P ≤ 0.0001), included studies (P ≤ 0.0001), synthesis of results (P ≤ 0.0001), interpretation of results (P = 0.035), financing and conflict of interest (P ≤ 0.0001), and registration (P ≤ 0.0001). These results showed the positive effect of PRISMA-A had on the quality of reporting of orthodontics systematic reviews. Nevertheless, the poor adherence revealed that there is still need for improvement in the quality of abstract reporting.

CONCLUSIONS

The quality of reporting of abstracts of orthodontic systematic reviews and meta-analyses increased after the introduction of PRISMA-A.

Self-Reported Changes in Oral Hygiene Habits among Adolescents Receiving Orthodontic Treatment

The prevalence of malocclusion and a need for orthodontic treatment is high. Orthodontic appliances increase biofilm accumulation by expanding plaque retention sites. The aim of this study was to investigate the self-reported changes in oral hygiene habits among adolescents receiving orthodontic treatment. A cross-sectional study of 291 patients aged 10–17 years (mean (M) = 12.98; standard deviation (SD) = 2.36) was conducted in the Department of Orthodontics, Lithuanian University of Medical Sciences (LSMU) Hospital (Kaunas, Lithuania) during the fall semester (October–January) of the 2017/2018 study year. An anonymous self-administered questionnaire covered background information, experience of orthodontic treatment, oral hygiene habits and the seeking of professional dental care. Statistical data analysis was performed using SPSS version 22. To establish relationships between categorical variables, Chi-squared tests (χ2) were used. A p-value ≤ 0.05 was set to indicate statistically significant difference. The univariate logistic regression analysis evaluated the probability of an event given a certain risk indicator, including odds ratio (OR) and its confidence interval (95% CI). Associations were found between the usage of auxiliary measures (OR = 1.797 (1.118–2.887), p = 0.015), tongue cleaning (OR = 1.712 (1.059–2.767), p = 0.028), mouth rinsing after meals (OR = 1.707 (1.048–2.781), p = 0.032) and experience of orthodontic treatment, respectively. More orthodontic patients underwent professional oral hygiene regularly than non-orthodontic patients (p = 0.024). More patients with fixed orthodontic appliances reported significantly changed oral hygiene habits, while more orthodontic patients with removable appliances did not change their oral hygiene habits.

Systematic review versus structured critical analysis

Objective: This analysis discusses common problems with systematic reviews (SRs) and presents a novel solution, the structured critical analysis (SCA) that can be incorporated into a SR or used as an alternative literature review design.Methods: A cross-sectional survey of current SRs related to interdisciplinary restorative dentistry was obtained by evaluating 100 current SRs for their self-reported methodological quality and its effect on scientific validity.Results: The preferred reporting items for systematic reviews and meta-analyses protocol (PRISMA) was used in 99/100 SRs, but only 8/100 reported a low risk of bias. High statistical heterogeneity precluding meta-analysis was found in 44/100 SRs. Only 94 paragraphs/100 SRs provided critical analysis.Discussion: Significant problems were found with current SRs that can compromise their reliability as the premier level of evidence for clinical science research. The reader must be aware of these deficiencies to correctly interpret the SR and cannot rely on the format alone.

Macrophages mediate corticotomy-accelerated orthodontic tooth movement

Clinical evidence has suggested that surgical corticotomy of the alveolar bone can accelerate local orthodontic tooth movement (OTM), but the underlying cell and molecular mechanisms remain largely unclear. The present study examined the role of macrophages played in corticotomy-assisted OTM. Orthodontic nickel-titanium springs were applied to the left maxillary first molars of rats or mice to induce OTM with or without corticotomy. Corticotomy enhanced OTM distance by accelerating movement through induction of local osteoclastogenesis and macrophage infiltration during OTM. Further analysis showed that macrophages were polarized toward an M1-like phenotype immediately after corticotomy and then switched to an M2-like phenotype during OTM. The microenvironment of corticotomy induced macrophage infiltration and polarization through the production of TNF-α. More importantly, the amount of OTM induced by corticotomy was significantly decreased after mice were depleted of monocyte/macrophages by injection of liposome-encapsulated clodronate. Further experiments by incubating cultured macrophages with fresh tissue suspension obtained from post-corticotomy gingiva switched the cells to an M1 phenotype through activation of the nuclear factor-κB (NF-κB) signaling pathway, and to an M2 phenotype through activation of the JAK/STAT3 signaling pathway. Our results suggest that corticotomy induces macrophage polarization first by activating the NF-κB signaling pathway and later by activating the JAK/STAT3 signaling pathway, and that these processes contribute to OTM by triggering production of inflammatory cytokines and osteoclastogenesis.

Evidence-Based Update on Diagnosis and Management of Gingivitis and Periodontitis

This article is an overview to update the practicing general dental practitioner about clinically relevant evidence-based topics published in the recent past in the diagnosis, etiopathogenesis, and management of gingivitis and periodontitis.
