{"title":"Does adjunctive phototherapy have better outcomes than adjunctive antibiotic therapy for the management of peri-implantitis?","authors":"Jacqueline Fraser, Vithurran Vijayenthiran","doi":"10.1038/s41432-024-01082-8","DOIUrl":"10.1038/s41432-024-01082-8","url":null,"abstract":"Elsevier’s Scopus, Web of Science and Pubmed through Medline identified 431 articles, which were reduced to 206 when duplicates were removed. 8 articles were screened, and 1 excluded after reading the full-text, leaving 7 studies. 6 of these were randomised controlled trials, and 1 a non-randomised controlled clinical trial. Studies selected were either blinded, double-blinded, split-mouth clinical studies, comparative or controlled clinical studies, or randomised controlled trials in humans. There were no limitations on year of publication or language of studies. Most studies had a control of mechanical debridement (MD) with adjuvant antibiotics; 1 was surgical therapy. The test group was MD with adjuvant phototherapy. Exclusions were in vitro reports, animal studies, treatment with sole laser therapy, treatment with no additional antimicrobial therapy alongside MD. Pre-prints, reviews, abstracts, opinion articles, editorials, case reports and case series were also excluded. Data were extracted electronically by a single author and a senior librarian from the 3 databases. Titles and abstracts of articles were screened by the author if they contained Medical Subject Headings either in free terms or with Boolean operators. Full text studies that met the inclusion criteria were included. Data were also searched manually in 6 journals. For missing or conflicting information, the author of the article was contacted for clarification. Data extracted were country of origin of article, study design, sample size, research groups, diagnostic criteria, frequency of intervention, follow-up visits, and outcome of parameters which included clinically: plaque index (PI), probing depth (PD), bleeding on probing (BOP) and radiographically: crestal bone loss (CBL). Additional data on lasers were also collected, although not all studies had complete data on this. RevMan was used for statistical analysis. Inconsistencies were evaluated using I2 value > 50% and Cochrane’s Q test, with a P value < 0.05 considered. Standard Mean Differences (SMD) were calculated and Confidence Interval was set at 95%. A random effects model was used for each meta-analysis. PI had no statistical difference, with high heterogeneity. PD had no statistical difference, with no heterogeneity. BOP had a statistically significant difference and a high level of heterogeneity, favouring adjunctive phototherapy. MBL had statistically non-significant differences between control and test groups, and no heterogeneity. The findings from the systematic review differed from the meta-analysis, suggesting that application of adjuvant phototherapy was equally as effective as adjunctive antibiotic therapy in outcomes such as PI, PD, BOP and MBL. The meta-analysis found that implants treated with adjuvant phototherapy had superior outcomes in relation to BOP only.","PeriodicalId":12234,"journal":{"name":"Evidence-based dentistry","volume":"25 4","pages":"204-205"},"PeriodicalIF":0.0,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41432-024-01082-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142617447","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Kotecha, Amelia Nadia Karim","doi":"10.1038/s41432-024-01083-7","DOIUrl":"10.1038/s41432-024-01083-7","url":null,"abstract":"Randomised control trials were identified via searches of PubMed, Embase, Web of Science and The Cochrane Library. Only randomised control trials involving adults with at least a single dental implant which had experienced peri-implant mucositis or peri-implantitis were considered. Within studies, one cohort must have been treated with a combination of mechanical debridement (MD) and non-surgical strategies, and the other solely by mechanical debridement. Outcomes were measured using periodontal indices such as bleeding on probing, and each group needed to comprise minimum five patients. Extracted information included the name of the lead author, size of patient groups, length of follow-up and the main results from the studies. The results indicated that in peri-implantitis the most effective treatment in reducing periodontal pocketing depths (PPDs) was photo biomodulation therapy and MD, while systemic antibiotics and MD were the most effective in improving clinical attachment loss and marginal bone loss. With regards to peri-implant mucositis; probiotics and MD yielded the best improvement in PPDs and plaque index, whereas systemic antibiotics with MD improved bleeding on probing the most. This analysis gives potentially useful data regarding specific treatment combinations for peri-implant disease. In light of this, it may help in guiding clinical decisions, but should be used in conjunction with recognised guidelines, and further high quality primary research is still required in the field.","PeriodicalId":12234,"journal":{"name":"Evidence-based dentistry","volume":"25 4","pages":"200-201"},"PeriodicalIF":0.0,"publicationDate":"2024-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41432-024-01083-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142617467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Manual screening of reference lists was performed, alongside searches in clinical trial registries to ensure comprehensive coverage. Only randomized controlled trials (RCTs) that compared antibiotic prophylaxis with no antibiotics or placebo in systemically healthy individuals undergoing dental implant surgery were included. Studies with a high risk of bias, non-randomized studies, and those without a placebo or control group were excluded. Studies focusing on medically compromised patients or other implant techniques (such as mini-implants or immediate placement in sites with apical pathology) were also excluded. Data extraction was carried out independently by two authors, with disagreements resolved through discussion among all review authors. The risk of bias for each included randomized controlled trial (RCT) was evaluated using the Cochrane Risk of Bias tool (RoB-2). The quality of evidence was assessed using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) framework. Meta-analyses were conducted using a random-effects model, and heterogeneity was checked with both the I² statistic and Q test. A total of 1267 studies were initially identified, with seven randomized controlled trials (RCTs) ultimately meeting the inclusion criteria, comprising data from 1,859 participants and 3014 implants. Four studies were high quality, and three were of moderate quality. Meta-analyses of these studies showed no statistically significant association between the use of antibiotic prophylaxis and a reduction in early dental implant failure (RR: 0.66, 95% CI: 0.30–1.47). The number needed to treat (NNT) to prevent one implant failure was 143, indicating a limited effect of antibiotics in preventing early implant failure. The study concluded that routine antibiotic prophylaxis does not significantly reduce the risk of early implant failure in medically fit patients. Given the very limited benefit and the concern of increasing antibiotic resistance, routine use of antibiotics in dental implant surgery should be avoided.","PeriodicalId":12234,"journal":{"name":"Evidence-based dentistry","volume":"25 4","pages":"206-207"},"PeriodicalIF":0.0,"publicationDate":"2024-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41432-024-01086-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142617549","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The search was conducted focusing on clinical studies where Enterococcus strains were isolated to assess their antimicrobial resistance. The search strategy was designed based on the PICO model, targeting patients with secondary/persistent endodontic infections (SPEI) and evaluating the resistance profiles of Enterococci to systemic antibiotics. A total of 584 studies were initially identified through database searches. After removing duplicates, 517 studies were excluded based on title and abstract screening, leading to the final inclusion of 11 clinical trials that met the eligibility criteria. The studies were conducted in various countries, including Brazil, Lithuania, Poland, Germany, Sweden, the United States, and Japan. The focus was on permanent teeth with post-treatment apical periodontitis undergoing endodontic retreatment. Data extraction was performed independently by two reviewers, who compiled details such as authorship, year of publication, country of study, sample groups, bacterial strains tested, antibiotics used, and resistance outcomes. The risk of bias was assessed using the ROB-2 platform, and all studies were considered to have a low risk of bias, with occasional minor deficiencies noted. The analysis revealed fluctuating resistance profiles of Enterococcus faecalis (E. faecalis) and Enterococcus faecium (E. faecium) to various antibiotics over time. E. faecalis isolated from teeth with SPEI showed intermediate resistance to 16 antibiotics. The most effective antibiotics identified were the combination of amoxicillin and clavulanate, followed by amoxicillin and benzylpenicillin. In patients with penicillin allergies, moxifloxacin and azithromycin were suggested as alternatives, albeit with caution due to their varying resistance levels. The antibiotics demonstrating the highest resistance patterns against E. faecalis included clindamycin, gentamicin, metronidazole, and rifampicin, which are contraindicated in SPEI cases. Ongoing monitoring of antibiotic resistance patterns is crucial for effective endodontic treatment protocols. The emergence of resistance among Enterococci, particularly E. faecalis, necessitates regular susceptibility testing to inform clinical decisions and improve treatment outcomes. The findings underscore the need for health professionals to stay informed about the evolving resistance landscape to ensure safe and effective therapeutic regimens in endodontics.","PeriodicalId":12234,"journal":{"name":"Evidence-based dentistry","volume":"25 4","pages":"194-195"},"PeriodicalIF":0.0,"publicationDate":"2024-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41432-024-01079-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142575647","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
