RESUMEN
AIM: To evaluate the efficacy of different techniques to seal the alveolus (flap advancement [FA], open healing with barrier [OHB], and open healing without barrier [OHNB]) during alveolar ridge preservation (ARP) in terms of horizontal ridge width resorption. MATERIALS AND METHODS: Randomized trials of at least 2 months duration comparing at least two techniques to seal the alveolus against each other or against spontaneous healing (SH) were eligible. Searches were conducted in MEDLINE via PubMed, EMBASE, Scopus, and Cochrane Central. Conventional meta-analysis, meta-regression, and network meta-analysis (NMA) were conducted, with clinical and tomographic ridge width changes as outcomes. Predictive intervals (95% PI) were reported. RESULTS: Twenty-two studies were included, accounting for 52 study arms. Meta-regression identified that the socket sealing technique and publication year explained the observed heterogeneity. NMA showed that FA and OHB led to significantly lower ridge resorption than SH, resulting in 1.18 mm (95% PI 0.21-2.13) and 1.10 mm (95% PI 0.49-1.69) wide alveolar ridges, respectively. No significant difference between OHNB and SH was found (0.46 mm, 95% PI -0.70 to 1.64). The treatment with the largest probability for ARP was FA (52.7%), followed by OHB (39.1%) and OHNB (8.2%). CONCLUSIONS: FA and OHB are efficacious techniques to seal the alveolus during ARP.

Le Fort I osteotomy is the most common procedure for maxillary advancement in cleft patients, and a significant relapse is expected in the postoperative period. This study purpose is to evaluate the maxillary relapse and associated factors in cleft lip and palate (CLP) patients submitted to standard Le Fort I advancement. This systematic review sought studies in PubMed, SCOPUS, and Cochrane and included papers that evaluated the maxillary relapse with at least 1-year postoperative period. The quality assessment was adapted following PRISMA statement. The initial electronic search found 345 papers, and the final selection included 10 studies. In total, 275 CLP patients were evaluated 198 had unilateral CLP and 41 had bilateral CLP. Isolated maxillary advancement was performed in 166 patients, while 109 had bimaxillary surgery. The mean relapse in horizontal and vertical plane was 1.2 mm (19.7%) and 1.0 mm (29.4%), respectively. In conclusion, a relapse after maxillary advancement in patients with CLP is expected, being higher in vertical plane. Patients with UCLP and those who underwent bimaxillary surgery had a higher relapse rate. Due to the miscellaneous data and methodologies, future prospective clinical trials should apply rigorous selection of CLP patients sample and methods for variable analysis to obtain more accurate results.

AIMS: To systemically review the literature on the effect of hand and sonic/ultrasonic instruments used for the non-surgical treatment of periodontitis. MATERIALS AND METHODS: Five databases were searched for randomized clinical trials that compared the results of periodontal treatment using hand and sonic/ultrasonic for nonsurgical periodontal treatment. Four meta-analyses were performed, using the calculated mean differences (MD) between baseline and 3-months or 6-months after periodontal treatment for clinical attachment level (CAL), and probing pocket depth (PPD). RESULTS: Eighteen studies were included. All included studies showed significant improvement, in at least one periodontal parameter, in both tested periodontal therapies. The sonic/ultrasonic instruments spend significantly less time in comparison to manual instrumentation. At both 3- and 6-months after periodontal therapy, no statistically significant differences were detected for CAL gain between therapies (MD; 95%CI: 0.05; -0.21-0.30 and -0.23; -0.59-0.12). Similarly, no statistically significant differences were detected for PPD reduction between therapies at 3-months of follow-up (MD; 95%CI: -0.03; -0.34-0.28). After 6-months, the PPD reduction was 0.21 (95%CI: -0.43-0.00, p=0.05). CONCLUSION: Similar results may be expected for the periodontal treatment performed with hand and sonic/ultrasonic instruments. However, further studies with lower risk of bias are warranted.

PURPOSE: Odontogenic infections are a common problem in dentistry, and their treatment often requires the use of antibiotics besides the removal of the source of infection, which frequently makes it more difficult for clinicians to make a decision regarding the choice of antibiotic. This study aimed to answer the following questions through the Patient, Intervention, Comparison, Outcome (PICO) format: When should antibiotics be used in dental infections (DIs)? Which are the most effective drugs? How long should antibiotics be administered? MATERIALS AND METHODS: This was a systematic review using the PubMed, Scopus, and Cochrane databases without restriction as to the period researched. The variables analyzed in each article were the number of odontogenic infections in each study, type of study, surgical intervention performed, antibiotics administered, statistical differences between groups studied, and patients' evolution after treatment. RESULTS: The search included 1,109 articles. After the full reading of 46 articles, 16 were included in the final review and 30 were excluded. A sample of 2,197 DI cases was obtained, in which 15 different antibiotics were used, with a 98.2% overall cure rate. CONCLUSIONS: The studies showed that antibiotics were prescribed only in situations of regional and/or systemic body manifestations. In the case of DIs, once drainage has been performed and/or the cause of infection has been removed, all antibiotics tested are equally effective with respect to clinical cure, and the choice of antibiotics is not as successful as the local intervention treatment procedure. When the real need for antibiotic therapy is detected, antibiotics should be used for the shortest time possible until the patient's clinical cure is achieved.

O objetivo deste artigo é descrever o clareamento de dentes vitais utilizando uma combinação de técnica caseira e de consultório. Foi utilizado peróxido de hidrogênio a 35% para a técnica de consultório em combinação com a técnica caseira utilizando peróxido de hidrogênio a 16%. A paciente foi monitorada quanto à mudança de cor dos dentes, de acordo com a escala Vitapan 3D-Master. Concluiu-se que, desde que bem planejado e com correto diagnóstico, a combinação de técnicas clareadoras é uma excelente opção de tratamento estético e conservador para clareamento de dentes com alteração de cor.
The aim of this paper was to describe a vital tooth bleaching employing a combination of in-office and at-home techniques. We used a 35% hydrogen peroxide for the in-office technique combined to home bleaching using hydrogen peroxide at 16%. The patient was monitored for teeth color change, according to the Vitapan 3D-Master scale. It was concluded that, with proper planning and diagnosis, the combination of bleaching techniques is an excellent option for aesthetic and conservative treatment of teeth chromatically altered.
