Purpose: Peri-implantitis is an inflammatory disease, characterized by the progressive loss of the peri-implant support bone tissue. The objective of this study was to assess whether implantoplasty is efficacious in promoting peri-implant health.Methods: In this systematic review and meta-analysis, a search without restrictions regarding language or date of publication was conducted across different databases. Grey literature search, Google Scholar search and manual searches were also carried out. Studies evaluating periimplant clinical parameters of individuals with peri-implantitis who had been submitted to implantoplasty were included. Study selection, data extraction, and risk of bias assessment were conducted. The outcome variables were implant probing depth, the percentage of implants with bleeding on probing or suppuration on probing, and the success rate of implants after implantoplasty. The predictor variable was implantoplasty and the follow-up time after implantoplasty. Data on sample size, implant location, implant diameter, and diagnostic criteria for peri-implantitis were also collected during data extraction. Meta-analysis, sensitivity analysis, and analysis of the probability of implant success after implantoplasty with the Kalan-Meier method were performed.Results: Ninety-four studies were assessed. Eight articles were included and 7 were incorporated into quantitative analyses. Subjects' mean age ranged between 50 to 70.7 years. The studies demonstrated that implantoplasty contributed to a significant improvement in the peri-implant condition, reducing the probing depth, bleeding and suppuration on probing. Overall, the included studies exhibited low risk of bias. Meta-analysis demonstrated that probing depth before implantoplasty was significantly higher than after implantoplasty (mean difference = -3.37 mm, confidence interval = -4.74; -2.00). This result was confirmed in the sensitivity analysis. The probability of success of implants at 6 months of follow-up after implantoplasty was 97.5% and at 24 months of follow-up was 94.7%.Conclusions: There is some evidence in the literature to recommend implantoplasty as a potential treatment for periimplantitis.

• Sleep should be explored in the anamnesis during prenatal care and the first childhood period. • The relationship between clock genes and amelogenesis should be further investigated. • A minacious oral examination must be performed on children whose mothers presented problems with sleep during pregnancy. Anatomical, physiological and hormonal changes occur in women during pregnancy. These phenomena can affect sleep quality, exerting a negative impact on health. Studies suggest that sleep disorders in this period can also affect the health of the fetus. Sleep disorders may interfere with the expression of genes associated with amelogenesis in the fetus. Clock genes are the basis of internal time keeping (circadian rhythm) and are involved in the formation of mineralized dental tissues. Fetal tooth formation is a complex physiological process that begins during intrauterine life, extending to around eight years of age, and can be affected by numerous internal, external, natal and postnatal events. Abnormalities in any stage of development of the dental enamel may have repercussions in the form of permanent defects and marks clinically represented by the presence of grooves, depressions and diffuse or demarcated opacities, which can compromise function and esthetics. Thus, changes in the awake/sleep pattern can affect the tooth formation process. The hypothesis proposed in this paper is that changes in sleep and the circadian rhythm can affect the molecular bases involved in enamel formation either during the intrauterine period or in the first years of life, causing enamel anomalies. This is because the maternal circadian rhythm has a relationship with the circadian clock of their offspring, demonstrating numerous consequences of the imbalance in this relationship on the child's systemic and oral health. New perspectives with regards to oral outcomes may arise from this discussion, such as a greater importance placed on sleep quality in pregnant women and infants. [ABSTRACT FROM AUTHOR]

• Chemical substances represent an option to selective removal of a deep decayed tissue. • Reduction of bacteria via photodynamic approach: an alternative for deep caries. • The use of new therapies can help minimally invasive approach. To test a chemical-mechanical method and antimicrobial photodynamic therapy (a-PDT) in combination to manage a deep dental carious lesion in a permanent molar pediatric patient. Due to specific characteristics of early-erupted teeth, as first permanent lower molars, techniques that provide less invasive tissue removal aiming keep healthy tooth parts, such as pulp tissue, are desired. Furthermore, especially to children, provide comfort, less noise and vibration are important issues that should be considered on the management of deep caries. The following case report presents an association of Papacarie Duo® (PD) and a-PDT used in a 9-year-old patient with a deep dental caries in the mandibular right first molar. After PD application, the carious tissue was carefully removed with the cavity stained for 1 min with rose bengal solution, irradiated with a high intensity LED constituting the a-PDT technique, and definitively restored with composite resin. At 6 months of follow-up, no signs of caries were verified, showing success to applied techniques. A microbiological evaluation attested the antimicrobial effects of the alternative procedures. Although it reached optimal clinical and bacterial reduction outcomes, the approach demonstrated an excessive length of time taken for the management of carious lesion. The use of new technologies should be encouraged, especially when treating deep caries aiming for a less invasive approach. [ABSTRACT FROM AUTHOR]
