title: Effect of whitening dentifrices containing optical agent on the variation of color, roughness and mass of a nanoparticulate composite resin

description: Abstract Introduction Blue covarine is a pigment that promotes optical changes in dental surfaces, providing whitening. Objective To evaluate in vitro the effect of bleaching dentifrices containing Blue covarine in nanoparticulate composite resin subjected to artificial darkening. Material and method One hundred sixty (160) specimens (PBs) of FILTEK Z350XT nanoparticulate composite resin were randomly divided into two experiments: Experiment I - 8 groups (n=10) submitted to brushing with an electric toothbrush for 1 month; Experiment II - 8 groups (n=10) submitted to simulated brushing for 6, 12 and 24 months. Groups were distributed according to the solution/dentifrice tested: CG (distilled water) and 7 test groups (GT1- Coltene Herjos, GT2- Colgate Total 12 Clean Mint, GT3- Colgate Luminous White Brilliant Mint, GT4- Oral B 3D White Perfection, GT5- Close Up White Now Glacier Fresh, GT6- Close Up White Attraction Diamond and GT7- Sorriso Xtreme White Evolution). Result In Experiment I, there was greater ∆E in GT6 in relation to CG, GT2, GT4 and GT5, with no differences among them. In Experiment II, after 24 months of brushing, there was greater ∆E in groups GT6 and GT7. After 24 months of simulated brushing, there was no change in roughness or loss of mass in any group. Conclusion The whitening effect promoted by dentifrices containing the agent Blue covarine seems to be related to the association of this agent with the abrasives present in the formulations of whitening dentifrices.

title: Prevalence of open bite and associated factors in preschoolers from Salvador-BA in 2019

description: Abstract Introduction The previous open bite is one of the most frequent types of malocclusions in preschoolers, being considered one of the most difficult occlusal problems to treat, mainly due to its multifactorial etiology and its intimate relationship with deleterious oral habits. Objective Identify the prevalence of anterior open bite in preschoolers in Salvador-BA as well as factors potentially associated with it. Material and method This is a cross-sectional study of 1577 preschool children (36 to 71 months) who attended municipal public daycare centers in Salvador-BA. Result The children's average age was approximately 54 months. Most were male (50.29%). The study population was predominantly composed of blacks and browns (92.02%). The prevalence of malocclusion was 40.46%, of which 14.02% of these children had an open bite. Regarding schooling, most mothers (55.86%) and fathers (50.08%) were equal to or higher than complete primary school. The digital sucking was common in 6.73% of the children and 10.39% used pacifiers. As protective factors for open bite were found the father's education level ≥ 1st complete degree (PR = 0.62 CI = 0.41-0.95) and nail-biting (PR = 0.34 CI = 0.21-0.56). As risk factors were found the use of pacifiers (PR = 17.98 CI = 10.91-29.62) and digital suction (PR = 11.04 CI = 6.0-20.32). Conclusion Educational measures aimed at parents and guardians are essential to prevent the development of harmful habits in preschoolers. Other studies are needed for in order to deepen the understanding of the identified protection factors in this study.

title: Clinical characteristics of Parkinson’s disease associated with dental treatment-related pain

description: Abstract Introduction Parkinson's disease (PD) results in unfavorable clinical conditions for oral health and there is no published study on pain during dental treatment in PD patients. Objective To investigate association between clinical characteristics of PD and the intensity of pain due to dental treatments. Material and method A consecutive sample of 70 patients with PD was used, in which 217 invasive dental procedures were performed. PD duration was collected from dental records; PD stage was defined using the Hoehn and Yahr scale; cognitive deficit, using the Mini Mental State Examination; depression, using the Beck Depression Inventory; and motor impairment, using the UPDRS-AVD scale. Patients were asked whether in the last month they felt any numbness, tingling, burning or pain sensation; as well as difficulty in smelling or tasting. Treatment-related pain was collected using a Numerical Pain Scale with values ranging from 0 to 10. Result the level of pain perceived by patients during dental treatment was not significantly associated with PD duration, PD stage, motor impairment or occurrence of depression. The frequency of patients who reported a higher level of pain was statistically higher among those with cognitive impairment and those who reported the presence of a greater number of sensory symptoms, especially numbness and burning. Conclusion Pain related to dental treatment in PD patients is associated with non-motor symptoms of these patients, specifically the cognitive impairment and the presence of sensory symptoms.

title: Oral changes associated with the presence of atopy in children: a cross-sectional study

description: Abstract Introduction Allergic diseases appear through the interaction between the environment, the individual, their predisposition to atopy and exposure to allergens. In atopic children there is a high prevalence of mouth breathers, as well as positive response to allergic prick tests. These respiratory changes have an association with orofacial deformities especially malocclusions. Objective To identify the frequency of children and adolescents that have atopies and search for a probable association between atopy and oral aspects like malocclusion and vicious oral habits. Material and method Medical records were taken of children and adolescents seen at two educational institutions in the city of Rio de Janeiro in the period between August 2017 and July 2018. Data were collected from medical records related to medical history, history of atopies and dental history. The data were transmitted descriptively through the chi-square test (p&lt;0.05). Result A total of 136 records were considered eligible for evaluation. During the anamnesis, 49 (36.0%) parents reported a history of atopy in their children adolescents. The prevalence of vicious oral habits was found in 87 children and adolescents (64.0%), being presented in 65.3% of the patients who had atopy (p&lt;0.05). Conclusion It can be observed that the prevalence of atopy reported in this population was 34.6% and there was also a high prevalence of vicious oral habits and dento-alveolar trauma in these patients. Relevant associations between the presence of atopies and history of dental trauma, malocclusion and the presence of oral vicious habits were observed, demonstrating a correlation between atopy and some aspects of oral health.

title: Influence of immediate dentin sealing on dentin bond strength with universal adhesive system

description: Abstract Introduction Imediate dentin sealing (IDS) is a procedure where a dentin adhesive is applied on the exposed dentin surfaces after its preparation to indirect restorations and before impression procedures. Objective The objective of the study was to evaluate the effectiveness of the immediate dentin sealing technique (SDI) in adhesive resistance, using the Universal adhesive system (Single Bond Universal, 3M ESPE). Material and method 30 bovine incisors were selected and divided into 3 groups (n = 10): Groups S (Without Immediate Dentin Seal), SDI (Immediate Dentin Seal with Adhesive) and SDIF (Immediate Dentin Seal with Adhesive + Flow Resin). The vestibular surface was worn with diamond-tipped conical tips until superficial dentin exposure. The smear layer simulation was carried out with # 600 granulation sandpaper for 30s and the dentin was treated according to the respective group. To simulate the temporary restoration, blocks of bisacrylic resin were cemented with zinc oxide cement. After 7 days, the final cementation of resin blocks with dual resin cement (RelyX ARC, 3M ESPE) was carried out. The specimens were sectioned to obtain 1mm2 fillets and subjected to the microtensile test. Result The ANOVA test showed a statistical difference between the groups evaluated. Higher values of bond strength were observed for the SDIF group (23.53 MPa), differing statistically from Group S (17,65 MPa) (p = 0.008). The SDI group showed an average bond strength (19.25 MPa), which did not differ statistically from groups S (p = 0.68) and SDIF (p = 0.07). Conclusion Based on the results, it is recommended the immediate dental sealing technique with adhesive + flow resin in dental exposures caused in the dental preparation for indirect restorations.

title: Immediate and late follow-up effects of class III early correction in cleft lip and palate patients treated with maxillary protraction

description: Abstract Introduction There is no consensus about the immediate and latte follow-up effects of maxillary protraction in cleft lip and palate patients. Objective To evaluate the stability of Class III early treatment in cleft lip and palate patients through maxillary expansion and protraction. Material and method The sample consists in three lateral cephalometric radiographs of 28 patients (mean pre-treatment age of 6.7±1.8 years) who presented cleft lip and palate and were treated with maxillary expansion and Petit facial mask. The angular (SNA, SNB, ANB, SN.GoGn, FMA, Z Angle) and linear (overjet, Co-A, Co-Gn, Nperp-A, Nperp-Pg, AO-BO) cephalometric measures were evaluated through the Dolphin® software, in three moments: T0 (initial), T1 (after treatment), and T2 (follow-up). Data were submitted to the analysis of variance (ANOVA) and Tukey-Kramer test. The correlation between cephalometric measures and patient’s age was determined by Pearson’s chi-squared test. Result The SNA, ANB, and AO-BO measures increased considerably (p&lt;0.05), and they did not present any differences compared to the initial ones after the follow-up time. The overjet measure increased (p&lt;0.05) after treatment and, even with its decrease at the follow-up time, it was still higher than at the beginning (p&lt;0.05). The Z angle showed improvement with treatment and remained stable at the follow-up time. Conclusion After treatment (maxillary expansion associated with protraction), there was a skeletal pattern improvement. During the follow-up period, those alterations decreased to a measure close to the beginning. There was an improvement in the dental pattern and facial profile that continued in the follow-up period.

title: Adhesion of monospecies biofilms from Streptococcus mutans and Candida albicans to different surfaces of conventional composite resins and bulk fill

description: Abstract Introduction Composite resins are restorative alternatives, but their surface may favor the accumulation of biofilm. Objective The aim of this study was to evaluate the in vitro adhesion of Streptococcus mutans (UA159) and Candida albicans (ATCC 90028) biofilms on the surface of conventional and bulk fill composites. Material and method Four brands of conventional and bulk fill composites were used, Aura Bulk Fill - SDI®, Premisa - Kerr®, Opallis- FGM® and Filtek bulk fill flow - 3M®. Artificial saliva was used to form the salivary film for 60 min at 37 ° C. The inoculum was standardized at 1x108 CFU/mL for S. mutans and 1x106 CFU/mL for C. albicans. The specimens (n = 8/group) were placed in 24-well plates, with BHI supplemented with sucrose for bacteria and RPMI 1640 for fungi. The biofilm formation was evaluated considering the colony forming units (CFU/mL). The data were analyzed by ANOVA and Tukey test (p &lt;0.05). Result For S. mutans biofilms, there was no significant difference in the CFU/mL count between the different types of composites (p = 0.119). In the CFU / mL count for C.albicans biofilm, the CFU/mL ranged from 7.78 to 8.34. There was a significant difference between brands for Candida, especially between conventional and bulk fill composites. Conclusion The present study demonstrates that there is no difference in adhesion for S. mutans biofilms.

title: Prevalence and severity of dental caries in elementary school students in a vulnerable municipality

description: Abstract Introduction Dental caries is still a public health problem in most industrialized countries, with a higher prevalence in the most socioeconomically vulnerable populations. Objective The aim of this study was to evaluate the prevalence and severity of dental caries and curative actions performed in students from 6 to 14 years of elementary school during four months of intervention. Material and method Cross-sectional study was conducted with 130 students from Sarandi / PR. To diagnose dental caries, dmft, DMFT and ICDAS II indices were used. The students received curative care according to the needs presented associated with preventive educational activities. Result The prevalence of dental caries was 70% and 83% according to the ceo-d / CPO-D and ICDAS II index, respectively. The codes for ICDAS II with thw highest prevalence were ICDAS 5 and 6 (1.57% and 3.69% respectively), while Code 4 was the least prevalent (0.30%).Most restorative treatments were performed by the ART technique (150 restorations). Ninety applications of fluoride varnish were performed on initial carious lesions. The most complex treatments were referred to the Basic Health Unit of the municipality. Of the 32 students referred, 21 attended and endodontic treatments and primary and permanent teeth extraction were performed. Conclusion The studied population has a high prevalence of caries and after four months of intervention, it was observed that ART was decisive for most treatment needs (59.2%), presenting itself as an efficient strategy that can be implemented in places that do not offer the structure of a dental office.

title: Evaluation of the interface between the straight prosthetic component and the Morse Cone-type internal connection of the dental implant in cross section by scanning electron microscopy

description: Abstract Introduction The implant-prosthetic abutment interface and the formation of its microgaps are relevant aspects in load transfer and biological response and are linked to the success of the rehabilitation. Objective To evaluate microgaps at the internal connection interface of the Cone Morse implant and the prosthetic component surface by means of scanning electron microscopy (SEM). Material and method Twenty 3.75 x 11.0 mm Cone Morse dental implants with their respective Singular® prosthetic abutments were used (Singular Implants, RN, Brazil). The straight trunnions were attached to the implants with a 32N/cm2 torque and the ES260 Epoxy Resin-based set emerged to allow longitudinal sectioning of the sample. The samples were analyzed and the microgaps measured in SEM (JEOL JCM-5700, MA, USA), and later the data were analyzed. Result The mean and standard deviation of the largest microgaps were observed in the apical part of the right and left side 1.44±2.68 and 1.16±1.49 μm, respectively. The smallest microgaps were on the upper implant right and left sides 0.60±0.73 and 0.66±0.67 μm, respectively. However, in the Kruskal-Wallis test there was no statistically significant difference between the implant regions, both for the left side (p=0.692) and right side (p=0.865). The Mann-Whitney test, there were no statistically significant differences between the sides for the different regions of the implants. Conclusion Even with the presence of microgaps in the implant-post interface, it presents a smaller size than the one presenting biological and mechanical problems. The samples analyzed for their fitting compatibility were satisfactory.

title: Prevalence and factors associated with tooth pain - a population-based study with adults and elderly from southern Brazil

description: Abstract Introduction Dental pain, or toothache, is defined as pain of orofacial origin, which occurs as a consequence of problems that affect teeth and support structures. Objective The objective of the present study was to analyze the factors associated with dental pain in individuals aged 18 years or older in the city of Rio Grande, RS, in the south of Brazil. Material and method Cross-sectional population-based study. 1,099 individuals were interviewed at home using a questionnaire with closed questions. Demographic, socioeconomic, general and oral health habits and behaviors were obtained. The report of dental pain in the 6 months prior to the survey was the study's outcome. The analyzes were based on Poisson regression. Result The prevalence of dental pain was 18.0% (95% CI 15.6; 20.4). When analyzing by age group, the prevalence of dental pain was 23.9% (95% CI 20.3; 27.4), 14.0% (95% CI 10.6; 17.5) and 10.4% (95% CI 5.8; 15.0), considering the adult population aged 20 to 39 years old, 40 to 59 years old and elderly, respectively. The highest prevalence of dental pain was for single individuals (PR = 1.50; 95% CI 1.11; 2.03), with less education (less than 8 years of study) (PR = 1.62; 95% CI 1.16; 2.27) and with the habit of grinding the teeth (PR = 1.67; 95% CI 1.18; 2.38). The elderly, on the other hand, had lower prevalence of dental pain when compared to adult individuals (PR = 0.50; 95% CI 0.32; 0.80). Conclusion Greater attention should be given to single, less educated, who grind their teeth and young adults.

title: Association between systemic conditions and the gravity of periodontal disease in patients attended at the UFCG School clinic

description: Abstract Introduction Periodontal disease is a chronic inflammatory disease of the protective and supporting tissues of the teeth. Systemic diseases or changes, such as diabetes, cardiovascular changes, lung changes, hormonal disorders and others, do not start periodontal disease, however they can accelerate a pre-existing disease increasing its progression and tissue destruction. Objective The present study aimed to evaluated, through clinical records, a possible association between systemic conditions and the severity of periodontal disease in patients seen at the Clinical School of Dentistry, Federal University of Campina Grande, Campus CSTR (UFCG-CSTR). Material and method The study evaluated 1035 medical records of patients who sought care at the Clinical School of Dentistry of the Federal University of Campina Grande, Campus CSTR during the years 2012 to 2017. Result The studied population had a prevalence of males (50.9%) and a diagnosis of gingival and periodontal disease of 63.6% and 35.8%, respectively. The most prevalent systemic conditions were hypertension (15.0%), diabetes (7.5%) and heart disease (5.8%). About 20.2% reported being smokers or ex-smokers. The use of medication was observed in 28.3% of the cases. There was a statistically significant association between periodontal disease, male gender, older age group, arterial hypertension, smoking or history of smoking and diabetes. Conclusion A number of teeth equal to or less than 10 was observed more frequently among patients aged 60 years or more; hypertensive, diabetic, cardiac patients and smokers or ex-smokers, thus suggesting a greater severity of periodontal disease in these individuals.

title: Effect of pigmenting agents on tooth enamel staining during immediate tooth whitening: an in vitro study

description: Abstract Introduction Considering the increased search for esthetic procedures, questions emerge about the maintenance and regression of color, especially regarding the need to restrict dark foods during bleaching procedures or their influence on the stability and effectiveness of the treatment. Objective To assess the influence of staining agents on tooth enamel during immediate bleaching treatment with 35% hydrogen peroxide. Material and method Sixty bovine teeth were divided into six groups (G) (n=10): G1: distilled water (control); G2: coffee; G3: cola soft drink; G4: wine; G5: mate tea; and G6: industrialized açaí. The samples were subjected to immediate bleaching using 35% hydrogen peroxide for 21 days (three applications of 15 minutes per session, every seven days) and pigment immersion between each session for 15 minutes. The color was assessed before starting bleaching and after 21 days, using a spectrophotometer. The data obtained were subjected to one-way ANOVA and heteroscedasticity analysis by the Welch and Brown-Forsythe tests. The Tamhane test was used for group comparison. Result The color change was visible to the naked eye, considering the mean ΔE in all groups tested was higher than 3.7. However, there was no statistical difference between the control group and the groups assessed. Conclusion The contact of staining agents on bovine tooth enamel did not affect the final result of the immediate tooth bleaching.
