The primary goal of the Brazilian Journal of Oral Sciences is to publish the outcomes of original investigations as well as invited reviews, case reports, short communications, and letters to the editor in the field of Dentistry and related disciplines. The Brazilian Journal of Oral Sciences is committed in publishing the scientific and technologic advances achieved by the dental community, according to the quality indicators and peer reviewed material, with the objective of assuring its acceptability at the local, regional, national and international levels.<br /><strong>Qualis</strong>:B1<br /><strong>Knowledge Area</strong>: Health Sciences<br /><strong>Foundation</strong>: 2002<br /><strong>Short title</strong>: Braz.

Due to its probability of reducing dental plaque accumulation, TCS can be added as a substance for oral hygiene. Aim: To evaluate the efficacy and antimicrobial capacity of TCS against <em>Pseudomonas aeruginosa </em>and <em>Streptococcus mutans</em>. Methods: This work evaluates the percentage of bacteria inhibition of <em>P. aeruginosa </em>(ATCC 27853) and <em>S. mutans </em>(ATCC 25175). TCS concentrations between 2 and 128 μg.mL-1 were tested. Results: An inhibitory potential of TCS was found against <em>S. mutans</em>. No percentage of inhibition was detected against <em>P. aeruginosa </em>(technical and biological triplicate). Conclusion: TCS, an antimicrobial agent used in dentifrices, can reduce <em>S. mutans </em>levels therefore these dentifrices should be indicated for patients with a high risk of caries. However, further study is needed, including antimicrobial analyses against other microbial conditions.</p> Jade Ormondes de Farias; Jamilca de Almeida do Espírito Santo; Ingrid Aquino Amorim, Taia Maria Berto Rezende Copyright (c) 2022 Jade Ormondes de Farias, Jamilca de Almeida do Espírito Santo, Ingrid Aquino Amorim, Taia Maria Berto Rezende Tue, 13 Sep 2022 00:00:00 +0000 Prevalence and influence of dental development anomalies in smile esthetics <p>Aim: To determine the prevalence of dental development anomalies and type of influence on the smile of adolescent students. Method: This was a cross-sectional and analytical study carried out in two public (A1) and two private (A2) schools chosen by lot in the city of Parnaíba-Piauí. The sample calculation was based on the target population: number of people enrolled in public and private schools between 15 and 19 years, in the city of Parnaíba-PI, which totaled 6209 students in 2020, according to a survey carried out by the Brazilian Institute of Geography and Statistics – IBGE. A questionnaire on epidemiological data and aesthetic self-perception of the smile was applied to 160 adolescents between 15 and 19 years old, from August 2020 to July 2021. The clinical examination was carried out under natural light, to check for the presence of anomaly(s) in the dental development. Students who presented only one pathology would be called group 1 (G1), those who presented two would be called group 2 (G2) and those who presented 3 or more would be called group 3 (G3). On the other hand, adolescents in whom no anomaly was evidenced would participate in the control group (CG), both in A1 and A2. Results: It was observed that 37.5% of the sample had only a type of dental anomaly, corresponding to 60 individuals. The most prevalent were enamel hypoplasia, fusion, transposition, agenesis, ectopic eruption, microdent and dens-in-dent. It was possible to verify a higher prevalence in the maxilla, private schools (76.6%) and females (86.6%). In 45% of adolescents with dental anomalies, embarrassment was observed when smiling. Conclusion: The prevalence was relatively high, highlighting the enamel hypoplasia, influencing the smile esthetics of a reasonable number of adolescents, whether for acquaintances, strangers or even for photographs.</p> Marcelo Lucio Sousa Silva Junior, Millena Lopes de Brito, Breno Wesley Leal Carvalho, Elen Maria Carvalho da Silva, Ana de Lourdes Sá de Lira Copyright (c) 2022 Marcelo Lucio Sousa Silva Junior, Millena Lopes de Brito, Breno Wesley Leal Carvalho, Elen Maria Carvalho da Silva, Ana de Lourdes Sá de Lira Tue, 06 Sep 2022 00:00:00 +0000 Effects of black tea tooth staining previously to 35% hydrogen peroxide bleaching <p>Aim: To determine if the artificial staining with black tea (BT) influences the enamel microhardness before in-office bleaching and if BT staining is necessary to evaluate the efficacy of bleaching with 35% hydrogen peroxide Methods: Enamel/dentin blocks were randomized into groups according to the staining protocol (n=5/group): (CO) control – maintained in artificial saliva solution (AS); (BT4) immersed in black tea solution for 4 h; (BT24) immersed in black tea solution for 24 h. After the staining protocols, all specimens were kept in AS for one week, followed by bleaching (three sessions of HP application for 40 min). Knoop surface microhardness (kgF/mm2) was determined at baseline (T0), after staining (T1), after 7 days of storage in AS (T2), and after bleaching (T3). The color (ΔE00) and coordinate changes (ΔL, Δa, Δb) were measured using a digital spectrophotometer at T0 and T3. Data were submitted to one-way (ΔE00, ΔL, Δa, Δb) or two-way ANOVA repeated measures (kgF/mm2) and Tukey’s test (a=5%). Results: The staining protocols (BT4 and BT24) promoted significantly lower microhardness (T1 and T2, p&lt;0.05) than CO, whereas CO was the only group to maintain microhardness values over time. Bleaching promoted perceptible ΔE00 without a significant difference among the groups regardless of the staining protocol (p=0.122). CO and BT4 showed no differences in terms of ΔL and Δa (p&gt;0.05), but BT4 displayed a higher Δb than CO. Conclusion: The artificial staining with BT negatively affected the enamel surface microhardness and was not essential to evaluate the efficacy of 35% hydrogen peroxide bleaching.</p> Samuel da Silva Palandi, Matheus Kury, Mayara Zaghi Dal Picolo, Fernando Luis Esteban Florez, Vanessa Cavalli Copyright (c) 2022 Samuel da Silva Palandi, Matheus Kury, Mayara Zaghi Dal Picolo, Fernando Luis Esteban Florez, Vanessa Cavalli Tue, 13 Sep 2022 00:00:00 +0000
