The prevalence of malocclusion and the relationship with oral habits in Brazilian children from two public primary schools was evaluated. The sample was composed of 112 children with mean age of 61 ± 6.67 months. The results demonstrated the presence of malocclusions in 75.8% (n=85). The oral habits was related by 34.8% (n=39). The open bite was the most prevalent malocclusion in the studied population and the oral habits was the decisive etiological factor.

The TiF4 application produces a titanium coating on enamel surface, reducing solubility in presence of cariogenic challenge. However, it is not established if this titanium also penetrates inside the enamel. The aim of this study was to evaluate in vitro the presence of this superficial coat and titanium penetration into human sound and decayed enamel after TiF4 application. Twenty-four unerupted third molars were mesiodistally cut and divided into two groups (GA - sound and GB – artificial decayed). After a 4% TiF4 application, each sample was fractured longitudinally (occlusal-cervical). Through microprobe analysis with energy dispersive spectrometer (EDS), titanium penetration could be observed inside the enamel. The McNemar test (p=0.267) showed that there was no difference between the groups analyzed regarding to titanium penetration, although in group A the titanium penetrated more deeply (Wilcoxon test, p=0.047). It could be concluded that there was no difference between the groups regarding the titanium penetration, but titanium penetrated more deeply into sound enamel compared to artificially decayed enamel.

The ectodermal dysplasia constitutes a group of hereditary disorders whose clinical manifestations can be defects in ectodermal structures. The hypohidrotic and anihidrotic are commonly types of ectodermal dysplasia.The main characteristics are dental anomalies, hypotrichosis and hypohidrosis. The oral rehabilitation of this patients is important for better social living, self esteem and oral function. This paper had as objective to relate and discuss a case of anihidrotic ectodermal dysplasia, describing the positive influence of an alternative rehabilitation treatment.

The presence of supernumerary teeth can interfere in normal occlusal development. The pediatric dentist should diagnose them as soon as possible, as most of the time they are asymptomatic. The objective of this paper is to show the presence of that dental anomaly in two pediatric patients, as well as the associated clinical complications with treatment.

Objective: To evaluate TIF4 preventive and therapeutic use in caries and erosive lesions. Material and Methods: Searches were performed in six databases. Studies evaluating TiF4 use in vitro, in situ, and in vivo in caries and erosive lesions were included and imported into VantagePoint™ (VP). Data about publication year, authors, country, journal, study design, outcomes, TIF4 vehicles, application and intervention time, cariogenic challenge, erosive cycles, effects (positive/ negative /null) and approach (preventive/therapeutic) were analyzed through VP and Excel. Results: 93 published studies were included and an increase in publications was observed between 2010 and 2021. Forty-three authors published three or more articles, of which 67.4% were developed in Brazil and published in Caries Research (22.6%). 69.9% were in vitro studies with erosion assays (59.1%) and with preventive approaches (67.4%). The principal vehicle was a solution (69.9%) with a 1-min single application (58.0%) and with an intervention time of 5-7 days (22.6%). The principal cariogenic challenge in vitro was pH cycling (11.8%); in situ was sucrose + biofilm (6.2%); and in vivo, biofilm (6.2%). The most used erosive cycle was 4× per day in in vitro studies (20.4%) and 1× in vivo (2.1%). A positive effect was observed in prevention (41.9%) and treatment (24.7%) studies. Conclusion: TIF4 has shown a positive effect in prevention and therapeutic treatments for dental caries and erosion.
