Background
The authors conducted a systematic review to assess changes in patients’ facial profiles resulting from orthodontic treatment with and without extraction of 4 premolars and to identify cephalometric parameters that can assist decision making in borderline cases.Types of Studies Reviewed
The authors conducted a systematic review of randomized clinical trials and observational studies comparing the 2 types of treatment (with and without premolar extraction) in terms of the changes in facial profile. The authors conducted an electronic search of the databases the Cochrane Library, PubMed MEDLINE, Embase, and Latin-American and Caribbean Health Sciences Literature.Results
The authors identified 1 clinical trial with 26 participants and 5 observational cohort studies, collectively involving 362 participants. The authors assessed cephalometric parameters and esthetic outcomes. Four studies used linear regression analysis to investigate esthetic interaction between treatment strategy and initial lower lip protrusion. The 4 studies determined that if the initial lip protrusion was beyond a determined point, esthetic preferences favored extraction, and if the initial lip protrusion was not to that point, esthetic preferences favored conservative treatment.Conclusions and Practical Implications
The results of the authors’ systematic review found no significant differences between the groups in terms of the esthetic outcomes. The cephalometric parameter of initial lip protrusion can help with decision making in borderline cases. 相似文献6.

The aim of this systematic review and meta‐analysis was to evaluate whether the use of calcium hydroxide (CH) liner improves the clinical success in the treatment of deep caries lesions of primary and permanent teeth. The review was reported in accordance with the PRISMA Statement. Only studies that evaluated deep carious lesions treated with and without a CH liner were included. The required outcomes had to be obtained by clinical, radiographic or laboratory evaluations. Statistical analyses were performed with the RevMan 5.2 program (The Cochrane Collaboration, Copenhagen, Denmark) for randomized clinical trials with at least 12 months of follow‐up, using fixed‐effect models at a significance level of P < 0.05. The literature search was performed in eight databases: PubMed (MEDLINE), Lilacs, IBECS, BBO, Web of Science, Scopus, SciELO and The Cochrane Library. A total of 17 studies were included (15 in primary teeth, two in permanent teeth). The overall risk difference for CH versus adhesive system in primary teeth was 0.06 [95% CI ?0.01 to 0.13], and the overall risk difference for CH versus GIC was 0.10 [95% CI ?0.01 to 0.22], with no significant differences between materials. CH liner did not influence the clinical success of treatment for deep caries lesions of primary or permanent teeth. Although the present analysis demonstrated that use of CH liner in deep caries lesions was unnecessary, the evidence was of moderate to very low quality; thus, further well‐designed, randomized and controlled clinical trials are necessary to provide stronger recommendations. 相似文献

Aims: The purpose of this study was to evaluate the efficacy of orthodontic bonding systems containing different antimicrobial agents, as well as the influence of antimicrobial agent incorporation in the bonding properties of these materials.Methods: Eight databases were searched: PubMed (Medline), Web of Science, Scopus, Lilacs, Ibecs, BBO, Scielo and Google Scholar. Any study that evaluated antimicrobial activity in experimental or commercial orthodontic bonding systems was included.Data extraction: Data were tabulated independently and in duplicated by two authors on pre-designed data collection form.Data synthesis: The global analysis was carried out using a random-effects model, and pooled-effect estimates were obtained by comparing the standardised mean difference of each antimicrobial orthodontic adhesive with the respective control group. A p-value?.05 was considered as statistically significant.Results: Thirty-two studies were included in the qualitative analysis; of these, 22 studies were included in the meta-analysis. Antimicrobial agents such as silver nanoparticles, benzalkonium chloride, chlorhexidine, triclosan, cetylpyridinium chloride, Galla chinensis extract, acid ursolic, dimethylaminododecyl methacrylate, dimethylaminohexadecyl methacrylate, 2-methacryloyloxyethyl phosphorylcholine, 1,3,5-triacryloylhexahydro-1,3,5-triazine, zinc oxide and titanium oxide have been incorporated into orthodontic bonding systems. The antimicrobial agent incorporation in orthodontic bonding systems showed higher antimicrobial activity than the control group in agar diffusion (overall standardised mean difference: 3.71; 95% CI 2.98 to 4.43) and optical density tests (0.41; 95% CI ?0.05 to 0.86) (p?.05). However, for biofilm, the materials did not present antimicrobial activity (6.78; 95% CI 4.78 to 8.77). Regarding bond strength, the global analysis showed antimicrobial orthodontic bonding systems were statistically similar to the control.Conclusions: Although there is evidence of antibacterial activity from in vitro studies, clinical and long-term studies are still necessary to confirm the effectiveness of antibacterial orthodontic bonding systems in preventing caries disease. 相似文献

Aim
The aim of this study was to systematically review the literature to answer the questions: (i) “Is periodontal treatment effective to improve clinical and immunological conditions in obese subjects?”; (ii) “Do obese subjects present different clinical and immunological response after periodontal therapy when compared to non-obese subjects?”Methods
Searches were performed in six databases up to August 2014. Interventional studies were included if the following data were described: (1) Obesity/overweight assessment; (2) definition of periodontal disease; (3) periodontal therapy; (4) inflammatory marker in serum/plasma, and/or clinical parameters of periodontal disease. Assessment of quality was performed with the Downs and Black scale. Meta-analyses were conducted with the available data.Results
Of 489 articles, 5 were included, and only 3 proceeded to meta-analysis of clinical outcomes. Included studies presented fair methodological quality. Statistical analysis demonstrated that periodontal therapy in obese subjects was effective to improve clinical outcomes. No clinical differences between post-therapy results of obese and non-obese were observed. Effects of periodontal therapy on inflammatory markers remain unclear.Conclusions
Periodontal treatment seems to be effective to improve healing in obese individuals. No differences on periodontal healing between obese and non-obese subjects were observed; however, only limited and fragile base of evidence was available for analysis.Clinical relevance
Periodontal treatment is effective to improve clinical and immunological periodontal parameters in adults. Also, obesity seems to not modify the periodontal healing after treatment.11.

Background: Toothbrushing might be associated with the development of soft tissue lesions. This systemic review aimed to examine soft tissue lesions caused by different bristle stiffnesses and bristle end-shapes in manual toothbrushes in adult individuals. Materials and methods: Scopus, EMBASE and PubMed databases were searched to find controlled trials that evaluated manual toothbrush bristle stiffness and/or end-shape in regard to soft tissue safety. The grey literature was also included in the search strategy. Two reviewers independently performed the screening, final selection and data extraction. To be included, studies had to have been performed using at least two manual toothbrushes differing in bristle stiffness and/or end-shape, and had to report any adverse effects on oral soft tissues after at least 7 days of follow-up. A meta-ethnography strategy was used for qualitative data synthesis. The Cochrane Collaboration tool was assessed to evaluate the risk of bias. Results: Thirteen studies were included from the 1,945 initially retrieved. Toothbrush bristle end-shape was investigated in six studies, bristle stiffness in two, and both features were investigated in five studies. Hard-bristle toothbrushes produced more gingival lesions than medium- and soft-bristle brushes. A slight gingival recession width increase was identified in the end-rounded group, compared with the tapered group. Only four studies presented adverse effects as the primary outcome. Conclusion: Soft and extra-soft toothbrushes tend to be safer. Oral soft tissue injuries are similar for both tapered and end-rounded bristles. Further studies investigating adverse effects as a primary outcome are recommended.Key words: Oral hygiene, toothbrushing, dental devices, home care, gingival recession 相似文献

ObjectivesTo evaluate the clinical effectiveness of adjunctive interventions in individuals undergoing rapid maxillary expansion (RME).Materials and MethodsMEDLINE, Web of Science, Cochrane, Scopus, LILACS, and Google Scholar were searched without restrictions up to June 2020. Trials involving participants undergoing orthopedic or surgical RME, along with adjunctive interventions, were included. Risk-of-bias assessments were performed using the Cochrane tool for randomized trials-2. The certainty level of evidence was assessed through the Grading of Recommendations Assessment, Development and Evaluation tool.ResultsSix randomized clinical trials, with low to high risk of bias, were included. Low certainty of the evidence suggested that low-level laser facilitated opening of the midpalatal suture during the active phase of RME. Likewise, moderate certainty demonstrated that low-level laser accelerated the healing process of the suture during the retention phase. The clinical impact of this outcome, that is, stability and retention time, was not evaluated. Very low evidence indicated that osteoperforations along the midpalatal suture increased maxillary transverse skeletal gains in young adults undergoing RME. Low evidence suggested that platelet-rich plasma therapy did not minimize the vertical and thickness bone loss after RME in the short term.ConclusionsBased on currently available information, the use of low-level laser associated with maxillary expansion seems to provide a more efficient suture opening and bone healing. Limited evidence suggests that osteoperforations improve the skeletal effects of RME in non-growing individuals. There are no adjunctive interventions capable of reducing the periodontal side effects of RME. 相似文献

The objective of the current study was to systematically evaluate the existing evidence in relation to the safety, quality, productivity or cost-benefit, and patient satisfaction of the procedures performed by the different groups of dental providers. Due to the diversity of the procedures performed and the outcomes measured, it was not possible to create pooled estimates in a meaningful manner. Therefore, summary results of individual studies are presented and critically evaluated. 相似文献
