ABSTRACT

Abstract: The purpose of this review was to systematically evaluate all the existing literature on the efficacy of treatments used to relieve the signs and symptoms associated with teething. A systematic search up to February 2021, without restrictions on language or date of publication, was carried out in MEDLINE/PubMed, SCOPUS, Web of Science, The Cochrane Library, EMBASE, LILACS, BBO, OpenGrey, Google Scholar, Portal de Periódicos da CAPES, clinicaltrials.gov, and the references of the included studies. Clinical studies that evaluated the effect of any intervention to alleviate the signs and symptoms associated with teething in babies and children were included. The risk of bias was assessed using the ROB-2 and ROBINS-I tools. The characteristics and results of the individual studies were extracted and synthesized narratively. The GRADE approach was followed to rate the certainty of the evidence. Three randomized and two non-randomized clinical trials were included. The outcomes of these five articles were classified as high or serious risk of bias. Three studies using homeopathy reported improvement in appetite disorders, gum discomfort, and excess salivation. One study showed a new gel with hyaluronic acid was more effective than an anesthetic gel in improving signs and symptoms such as pain, gingival redness, and poor sleep quality. Another study applied non-pharmacological treatments, which were more effective, especially against excess salivation. Although the present systematic review suggests some therapies could have a favorable effect on signs and symptoms related to teething, definitive conclusions on their efficacy cannot be drawn because of the very low certainty of the evidence. The existing literature on the subject is scarce and heterogeneous and has methodological flaws; therefore, further high-quality investigations are necessary.

ABSTRACT

ABSTRACT Objective To describe and evaluate the xylitol products' applicability and its effects in the health area worldwide utilizing a bibliometric analysis from randomized controlled trials (RCT) with humans. Material and Methods Electronic searches were carried out in Medline/PubMed, Scopus, Cochrane Library, Web of Science, and VHL databases. The main data extracted were: year, area of applicability, type of treatment, country, journal, xylitol posology and concentration, presentation form, outcomes, and effects. Results From 1476 studies, 257 were included. These studies were published between 1973-2021. The majority was carried out in dentistry (73.9%) and under preventive treatment (67.4%). These studies were developed in the USA (15.4%) and published in Caries Research (6.6%). The posology and concentration ranged between 0.004-67 g/day and 0.002-100%, respectively. The xylitol is usually used in the chewing gum form (44.0%), and for antimicrobial activity evaluation (38.5%). A positive effect was observed in 204 studies (79.3%) and was associated with xylitol concentration ≥ 15(p=0.007). Side effects were reported in 8.2and were associated with posology ≥ 5 g/day (p=0.03). Conclusion Most studies with xylitol were conducted to prevent diseases in the dentistry field. The chewing gum form and antimicrobial activity evaluation were more frequent. Most xylitol products have a positive effect, and few studies report side effects.

ABSTRACT

Abstract This study aimed to evaluate the in vitro effect of a single application of experimental nanocomposite solutions on the prevention of dental caries around orthodontic brackets. The specimens were exposed to mesoporous silica (MS) nanocomposites containing fluoride by association with titanium tetrafluoride (TiF4) or sodium fluoride (NaF). Nanocomposites also could contain calcium and groups were described as MSCaTiF4, MSTiF4, MSCaNaF, MSNaF, and controls (TiF4, and NaF). Specimens were subjected to the formation of a multispecies biofilm to generate a cariogenic challenge. After 24h, both pH and total soluble fluoride concentration of the culture medium were assessed. Mineral loss was evaluated by percentage of surface mineral loss (%SML), mineral volume variation (ΔZ) of inner enamel and polarized light microscopy (PL). Linear (Ra) and volumetric (Sa) surface roughness and scanning electronic microscopy (SEM) were used to assess enamel topography. Statistical analyses were conducted considering p<0.05. MSNaF had the highest value of culture medium pH after cariogenic challenge, similarly to MSTiF4. All nanocomposite solutions released less fluoride than their controls NaF and TiF4 (p<0.05). All nanocomposite solutions presented lower %SML compared to their respective control groups (p<0.05). Lower Ra, Sa and ΔZ were observed for experimental groups compared to TiF4 (p<0.05). The results were confirmed by PL and SEM analysis. The experimental nanocomposite solutions contributed for lower enamel demineralization around orthodontic brackets.


RESUMO Este estudo teve como objetivo avaliar o efeito in vitro de uma única aplicação de soluções experimentais de nanocompósitos na prevenção de cárie dentária em braquetes ortodônticos. Os espécimes foram expostos a nanocompósitos de sílica mesoporosa (MS) contendo fluoreto por associação com tetrafluoreto de titânio (TiF4) ou fluoreto de sódio (NaF). Os nanocompósitos também podem conter cálcio e os grupos foram descritos como MSCaTiF4, MSTiF4, MSCaNaF, MSNaF e controles (TiF4 e NaF). Os espécimes foram submetidos à formação de um biofilme multiespécie para gerar um desafio cariogênico. Após 24h, o pH e a concentração de flúor solúvel total do meio de cultura foram avaliados. A perda mineral foi avaliada pela porcentagem de perda mineral superficial (% SML), variação do volume mineral (ΔZ) do esmalte interno e microscopia de luz polarizada (PL). A rugosidade superficial linear (Ra) e volumétrica (Sa) e a microscopia eletrônica de varredura (MEV) foram utilizadas para avaliar a topografia do esmalte. As análises estatísticas foram realizadas considerando p <0,05. MSNaF apresentou o maior valor de pH do meio de cultura após o desafio cariogênico, semelhante ao MSTiF4. Todas as soluções de nanocompósitos liberaram menos flúor do que seus controles NaF e TiF4 (p <0,05). Todas as soluções de nanocompósitos apresentaram% SML menor em comparação com seus respectivos grupos de controle (p <0,05). Ra, Sa e ΔZ menores foram observados para os grupos experimentais em comparação ao TiF4 (p <0,05). Os resultados foram confirmados por análises PL e SEM. As soluções experimentais de nanocompósitos contribuíram para a menor desmineralização do esmalte ao redor dos braquetes ortodônticos.

ABSTRACT

Abstract The objective of this work was to evaluate the relationship between factors associated with the COVID-19 pandemic and depression, anxiety, and stress (DAS) in dentists. Factors associated with the COVID-19 pandemic were evaluated using a questionnaire and scores of the Depression, Anxiety, and Stress Scales-21 were measured. The differences between the DAS scores based on the factors associated with the COVID-19 pandemic were tested through the successive application of multivariate analysis of variance (MANOVA, α = 0.05). After a sample size calculation, 998 participants with a mean age of 39.39 (± 11.69) years were included. The effect size indicated that changes in sleep quality (η2 = 0.161), eating habits (η2 = 0.057), and physical health (η2 = 0.051) were the ones that most negatively affected DAS scores. The highest DAS scores were observed in professionals who lived with someone at high-risk for COVID-19 (p < 0.001) and in those who did not engage in leisure activities during the pandemic (p < 0.001). Dentists who worked on the frontline against COVID-19 had higher scores of anxiety and stress (p = 0.029). The highest scores for anxiety, depression, and/or stress were seen in dentists living with someone at high-risk for COVID-19, who acts on the frontline, who does not practice in leisure activities during the pandemic, who completely changed eating habits, quality of sleep and physical health during the pandemic. In general, DAS levels of dentists were associated with factors related to the COVID-19 pandemic.

ABSTRACT

Introduction: Avulsion is a serious injury that causes damage to dental and supportive tissues, and is characterized by complete displacement of a tooth from its socket. In most situations, replantation is the treatment of choice for permanent tooth avulsion, and appropriate management is critical for a good prognosis in these cases. Previous studies have shown that the level of knowledge of dentists regarding the management of an avulsed tooth is deficient and have underscored the importance of continuing dental education to further the knowledge of general dentists in the urgency management of permanent avulsed teeth. Objective: This report aims to present a step-by-step clinical sequence involving the reimplantation of a mature permanent tooth that suffered avulsion,following the CARE guide. Case report: Tooth 21, stored in milk, was reimplanted 2 hours after avulsion and stabilized with flexible containment. The clinical steps were carried out according to the recommendations of the International Association of Dental Traumatology. Endodontic treatment was started five days after reimplantation, with periodic changes of intracanal medication. The patientis currently under follow-up, with no negative signs or symptoms related to avulsion. Conclusion: Dental reimplantation after avulsion should be performed after a thorough systemic and oral diagnosis and tooth storage conditions, with a clinical protocol based on scientific evidence of associations of dentoalveolar trauma.


Introdução: A avulsão é uma injuria grave que causa sérios danos aos tecidos de suporte do doente e é caracterizada pelo completo deslocamento do elemento dentário de dentro do alvéolo. O reimplante é, na maioria das situações, o tratamento de escolha para o dente permanente avulsionado e uma conduta correta é necessária para um bom prognostico nestes casos. Estudos prévios mostram que o conhecimento de dentistas sobre o manejo de um dente que sofreu avulsão é deficiente e destacam a importância da educação continuada, com a intenção de aumentar o nível de conhecimento de dentistas clínicos frente a urgências envolvendo dentes avulsionados. Objetivo: este relato tem como objetivo apresentar uma sequência clínica passo-a-passo envolvendo o reimplante de um dente permanente maduro que sofreu avulsão, seguindo o guia CARE. Relato do caso: O dente 21, armazenado em leite, foi reimplantado 2 horas após a avulsão e estabilizado com contenção flexível. As etapas clínicas foram realizadas conforme as recomendações da Associação Internacional de Traumatismos Dentários. O tratamento endodôntico foi iniciado cinco dias após o reimplante, com trocas periódicas de medicação intracanal. Atualmente o paciente encontra-se em acompanhamento, sem sinais ou sintomas negativos relacionados a avulsão. Conclusão: O reimplante dental após avulsão deve ser realizado após minucioso diagnóstico e condições de armazenamento do dente, com protocolo clínico embasado nas evidências científicas das associações de traumatismos dentoalveolares.

ABSTRACT

The presence of white spots due to dental fluorosis can cause aesthetic discomfort, being one of the factors for a search for dental treatment. Objective: Report a clinical case in which the aesthetic complaint was solved through the association of the dental bleaching to the microabrasion technique. Case report: Male patient, 13 years, attended to the Integrated Clinic of the School of Dentistry of the Federal University of Rio de Janeiro, with fluorosis, mainly in the antero-superior teeth and aesthetic complaint. Initially, it was made an immediate bleaching with hydrogen peroxide at 35%, in 3 sessions of 15 minutes each, to soften the disparity of shades between tooth-stain. The result was insufficient and the dental microabrasion technique was adopted. A pumice paste was applied together with gel of phosphoric acid at 37% under relative isolation, in a total of 8 applications (1 minute each). At the end of each application, it was made an abundant water washing, microengine mounted fine-grained disc polishing and topical application of neutral NaF2 in gel (4 minutes each application) to eliminate possible postoperative sensitivity. Conclusion: The dental bleaching and the microabrasion technique promoted satisfactory immediate clinical results that increased self-esteem of the patient in a minimally invasive way to dental structure.


Introdução: A presença de manchas brancas por fluorose dentária pode causar desconforto estético, sendo um dos fatores para busca de tratamento odontológico. Objetivo: Relatar um caso clínico em que a queixa estética foi resolvida através da associação do clareamento dentário à técnica de microabrasão. Relato do caso: Paciente do sexo masculino, 13 anos, compareceu a Clínica Integrada da Faculdade de Odontologia da UFRJ, com fluorose, principalmente nos dentes ântero-superiores e queixa estética. Inicialmente, realizou-se clareamento imediato com peróxido de hidrogênio a 35%, em 3 sessões de 15 minutos, para suavizar a disparidade de tons entre mancha-dente. O resultado obtido foi insuficiente e a técnica de microabrasão dentária foi adotada. Uma pasta de pedra pomes foi aplicada juntamente com gel de ácido fosfórico a 37% sob isolamento relativo, perfazendo um total de 8 aplicações (1 minuto cada). Ao final de cada aplicação, foi realizada lavagem abundante com água, polimento com disco de granulação fina montado em micromotor e aplicação tópica de NaF2 neutro em gel (4 minutos cada aplicação) para eliminar possível sensibilidade pós-operatória. Conclusão: O clareamento dentário e a técnica de microabrasão promoveram resultados clínicos imediatos satisfatórios que elevaram a autoestima do paciente, de maneira minimamente invasiva para estrutura dentária.

ABSTRACT

The management of fractured permanent teeth due to dental trauma in young patients is a challenge that requires an efficient approach. Objective: Describe a conservative and multidisciplinary treatment of a case of dental trauma in a 13 years-old boy. Case report: At clinical examination was verified enamel and dentin fracture in the left upper central incisor and a fracture with pulp exposure in the right upper lateral incisor, with subgingival extension of its margin at lingual surface, and no swelling or tooth displacement was observed. At radiographic evaluation, no pulp or periradicular disturbances were verified. It was proposed the surgical lengthening of the clinical crown of the right upper lateral incisor for later performing endodontic treatment. It was decided to make direct composite resin restorations in both fractured teeth, instead of doing a prosthetic treatment in the affected lateral incisor, such as the placement of a full ceramic crown, in an attempt to perform a less invasive treatment, mainly due to the age of the patient. At a two years follow-up visit was observed the maintenance of the health of periapical tissues and the absence of clinical alterations. Conclusion: The restorations were kept in good conditions and aesthetics was considered satisfactory by professionals, patient and parents.


Introdução: O manejo de dentes permanentes fraturados por traumatismo dentário em pacientes jovens é desafiador e requer uma abordagem eficiente. Objetivo: Descrever o tratamento conservador e multidisciplinar em um caso de traumatismo dentário de um menino de 13 anos de idade. Relato do caso: Ao exame clínico foi verificada uma fratura de esmalte e dentina no incisivo central superior esquerdo e uma fratura complicada no incisivo lateral superior direito, com extensão subgengival da margem na face palatina, e não foram observados edema ou deslocamento dentário. Ao exame radiográfico, não foram verificadas alterações pulpares ou perirradiculares. Foi proposta realização de aumento da coroa clínica do incisivo lateral superior direito para posterior realização do tratamento endodôntico. Para os dois dentes traumatizados foi proposta a realização de restauração direta com resina composta, proporcionando um tratamento menos invasivo ao incisivo lateral superior direito, ao invés de submetê-lo a um tratamento protético, como a colocação de uma coroa total cerâmica, principalmente devido à pouca idade do paciente. Na visita de dois anos de acompanhamento, observou-se a manutenção da saúde dos tecidos periapicais e ausência de alterações clínicas. Conclusão: As restaurações se mantiveram em boas condições e a estética foi considerada satisfatória pelos profissionais, paciente e pais.

ABSTRACT

ABSTRACT Objective: The aims of this study were to identify the main characteristics regarding the shape and size of the craniofacial region in patients with sickle cell anemia (SCA) and sickle cell trait (SCT) and in unaffected patients using geometric morphometrics and to check the efficiency of this method. Material and Methods: A cross-sectional analytical study of 45 patients (15 in each group) was performed. Lateral radiographs of the skull were used for the analysis. Seventeen landmarks and semilandmarks were placed for the measurements. The Pocrustes analysis of variance (ANOVA), regression analysis, multivariate analysis of variance, canonical variate analysis, Mahalanobis and Procrustes distances and unweighted pair group method with arithmetic mean (UPGMA) clustering were performed. Allometric effects and sex characteristics were not statistically significant (p> 0.05). Results: There were, however, significant differences (p< 0.05) in craniofacial shape among SCA, SCT and unaffected individuals. Those with SCA showed variations in the shape of the external auditory meatus and at the base of the occipital bone, in addition to the mandibular setback and upper incisor inclination, with a tendency towards prognathism. The individuals with SCT exhibited a similar craniofacial shape to those with SCA, but with slighter variations. Moreover, those with SCT were statistically closer in resemblance to unaffected individuals, given that SCT is not regarded as a disease. Conclusion: This demonstrates the efficiency of geometric morphometrics in the categorization of the assessed groups.

ABSTRACT

Abstract The aim of this study was to compare the effects of a single application of a new calcium mesoporous silica nanoparticle (Ca2+-MSN) versus other calcium and/or fluoride products against dental erosion. Enamel blocks were half-covered and assigned to six groups (n = 10): Ca2+-MSNs; casein phosphopeptide-amorphous calcium phosphate mousse (CPP-ACP); CPP-ACP/F− (900 ppm F−); titanium tetrafluoride (TiF4 1%); sodium fluoride (NaF 1.36%); and Milli-Q® water (negative control). A single application for each product was completed on the exposed areas of the blocks and were submitted to an erosive challenge. Differences in volumetric roughness (Sa), and tooth structure loss (TSL) by use of three-dimensional noncontact optical profilometry were evaluate. Scanning electron microscopy (SEM) was performed. Analysis of variance and Tukey's test for Sa and the Kruskal-Wallis and Mann-Whitney U tests (p< 0.05) for TSL, respectively. Results: When evaluating Sa, all products presented differences in roughness when compared with the control group (p< 0.05) but not with each other (p > 0.05). However, when analyzing the TSL, it was observed that Ca2+-MSNs, TiF4, and NaF were more effective in preventing dental erosion versus CPP-ACP, CPP-ACP/F−, and Milli-Q® water (p< 0.05). In the SEM images, the negative control presented the worst loss of dental structure, with more porous enamel. Ca2+-MSNs were as effective as TiF4 and NaF to reduce the tooth structure loss.


Resumo O objetivo deste estudo foi comparar os efeitos de uma única aplicação de uma nova nanopartícula de sílica mesoporosa de cálcio (Ca2+ -MSN) versus outros produtos à base de cálcio e / ou fluoreto contra a erosão dentária. Blocos de esmalte foram parcialmente cobertos e distribuídos em seis grupos (n = 10): Ca2+ -MSNs; fosfopeptídeos de caseína/fosfato de cálcio amorfo (CPP-ACP); CPP-ACP / F- (900 ppm F-); tetrafluoreto de titânio (TiF4 1%); fluoreto de sódio (NaF 1,36%); e água Milli-Q® (controle negativo). Uma única aplicação para cada produto foi realizada nas áreas expostas dos blocos e submetida a desafio erosivo. Diferenças na rugosidade volumétrica (Sa) e na perda de estrutura dentária (TSL) por meio de perfilometria tridimensional de não contato foram avaliadas. Microscopia eletrônica de varredura (MEV) foi realizada. Foram realizadas análise de variância e teste de Tukey para os testes Sa e Kruskal-Wallis e Mann-Whitney (p<0,05) para TSL, respectivamente. Na avaliação de Sa, todos os produtos apresentaram diferenças de rugosidade quando comparados ao grupo controle (p<0,05), mas não entre si (p> 0,05). No entanto, ao analisar o TSL, observou-se que Ca2+ -MSNs, TiF4 e NaF foram mais eficazes na prevenção da erosão dental versus CPP-ACP, CPP-ACP / F- e Milli-Q® (p<0,05). Nas imagens de MEV, o controle negativo apresentou a pior perda de estrutura dentária, com o esmalte mais poroso. A Ca2+ -MSNs foi tão eficaz quanto o TiF4 e o NaF para reduzir a perda da estrutura dentária.

ABSTRACT

Abstract Objective: To evaluate the effect of a calcium nanocompound on the reduction of erosive tooth wear and abrasion. Material and Methods: Bovine enamel specimens (BE), were randomly assigned to the following groups (n = 10): G1 = Calcium mesoporous silica nanoparticles (Ca2+MSNs); G2 = casein phosphopeptide-amorphous calcium phosphate (CPP-ACP, 2% CPP-ACP, GC®); G3 = casein phosphopeptide-amorphous calcium fluoride phosphate (CPP-ACFP, 2% CPP-ACP + 900 ppm F-, GC®); G4 = sodium fluoride NaF (900 ppm F-, positive control); and G5 = distilled and deionized water (negative control). Each product was applied to the exposed area for one minute, three times per day for three consecutive days, and followed by the immersion of the specimens in Sprite Zero™ - a low-pH solution (2.58) for five minutes (Coca-Cola™). After the first and last erosive challenges of the day, the specimens were submitted to abrasion in a toothbrush machine for 15 seconds (200 g/BE). The specimens were analysed using 3D non-contact optical profilometry, with tooth structure loss (TSL) measurements and scanning electron microscopy (SEM). TSL values were analysed by Kruskal-Wallis and Mann-Whitney tests (p<0.05). Results: There were no significant differences between G1 (10.95 µm) and G3 (10.80 µm) treatments for TSL values; however both resulted in significantly reduced TSL values compared with the G5 (16.00 µm) (p<0.05). The G4 (12.26 µm) showed no statistically significant difference when compared to the G5 (16.00 µm). The groups G1 and G3 presented higher surface preservation than the G5. Conclusion: Ca2+MSNs was effective for reducing tooth surface loss caused by erosive tooth wear and abrasion.

ABSTRACT

Abstract Objective: To evaluate the scientific evidence concerning the behavior rating scales efficiency to identify behavioral changes in preschool children undergoing dental treatment, through a systematic review. Material and Methods: MEDLINE/PubMed, Scopus, Cochrane Library, Web of Science, BVS databases and grey literature were searched. Also, a hand search of the included studies reference lists was conducted. Studies that evaluated healthy preschoolers' behavior before and after invasive dental treatments to observe behavioral changes were included. Two independent reviewers selected studies, extracted data and analyzed the risk of bias with a tool for before-and-after studies. The certainty of the evidence was evaluated with the GRADE approach. Results: Three studies were included. The Frankl Scale and North Carolina Behavior Scale were used in these studies. Both scales were able to identify behavioral changes in preschool children undergoing a dental intervention, although two of these included studies were considered fair with a high risk of bias, and one considered good with a low risk of bias. Conclusion: Although Frankl and North Carolina behavior scales were able to identify changes in the children`s behavior during dental treatment, these findings are not supported by strong evidence. Thus, further well-designed studies are needed to confirm this evidence.

ABSTRACT

Abstract Objective: To evaluate the influence of cavosurface vestibular bevel (CSVB) application on the clinical success (CS) of class IV restorations of traumatized permanent teeth, the influence of the number of fracture angles and dental trauma recurrence (DTR) on the restorations retention rate (RRR) and incidence of pulp necrosis (PN). Material and Methods: Fifty-seven children and adolescents with enamel and dentin fractures requiring C-IV restorations were randomly allocated in groups with CSVB and without CSVB. The primary outcomes were the CS of restorations, evaluated using modified USPHS criteria, and the incidence of PN after a 6-months follow-up. As secondary outcomes, the influence of the number of fractured angles and the DTR on the RRR and on the incidence of PN were evaluated (p>0.05). Results: Of 57 children and adolescents, 74 teeth were restored, and 71 completed the six-month follow-up analysis. Teeth restored with and without CSVB displayed similar CS as well as the same incidence of PN (p>0.05). The number of fractured angles did not influence the RRR and DTR was not associated with PN (p>0.05). DTR was associated with a lower RRR (p<0.001). Conclusion: Cavosurface vestibular bevel did not influence the clinical success of Class IV restorations or incidence of PN after 6-months follow-up. DTR did not influence the incidence of pulp necrosis, but did negatively influence the restorations retention rate. The number of fracture angles did not influenced in the restorations retention rate.

ABSTRACT

Abstract Objective: To evaluate traumatic dental injuries (TDI) in primary teeth and the association of gender and age with different injuries. Material and Methods: Records of patients with TDI in primary teeth were included. The following parameters were registered: gender and age, place of trauma, cause of trauma, affected tissue and tooth, number of injured teeth, type of injury, and gingival and bone damage. A logistic regression analysis was performed to explore the interaction between gender and age on the occurrence of types of injuries (p≤0.05). Results: The total of 721 records were evaluated and 370 records were included, being 61.6% boys and 60.5% children aged 0-3 years old, with 658 primary teeth affected. The support tissue was most affected (496/658), followed by dental tissue (139/658). Enamel/dentine fracture with pulp exposure (n=51) and intrusion (n=131) were the most common injuries of dental and support tissues, respectively. In general, boys suffered more traumas than girls, regardless of the age range. As for concussion, logistic regression confirms that gender and age are also influencers. Girls (OR=1.822, CI = 1.050-3.164, p=0.033) in the 4-6 year age group (OR=2.15, CI = 1.239-3.747, p=0.007) are more likely to have concussions. Children age 4-6 years were less likely to suffer an intrusion (OR=0.496; CI = 0.278-0.886; p=0.018). Conclusion: Gender and age influence concussion and intrusion in the primary teeth.

ABSTRACT

Abstract Objective: To evaluate the topography and microhardness of composite resin restorations submitted to different finishing and polishing systems before and after erosive challenge. Material and Methods: Thirty standardized cavities prepared in enamel-dentin blocks of bovine incisors were restored with Z350 composite resin, and randomly distributed into three groups (n=10) according to the finishing and polishing systems: G1 = Soflex 4 steps, G2 = Soflex Spiral 2 steps and G3 = PoGo (single step). The specimens were half protected with nail varnish and submitted to five immersions in Pepsi Twist®, for 10 minutes each, five times/day during six consecutive days. The initial and final challenge surface microhardness (SMHinitial and SMHfinal) of the composite resin was evaluated and the percentage of SMH loss (%SMHL) was calculated. After protection removal, the topographic change linear (Ra) and volumetric (Sa) roughness was evaluated in initial and final areas by using 3D non-contact optical profilometry and scanning electron microscopy (SEM). Data were analyzed by paired Student's t-test, Kruskal-Wallis test, and by ANOVA and Tukey's test. Results: There was significant intra-group %SMHL in composite resin (p<0.05). Differences among groups in %SMHL, Ra/Sa in resin composite were not observed (p>0.05). SEM images revealed structural changes between the initial and final surfaces for all groups. Conclusion: The three types of finishing and polishing systems had a similar influence on %SMHL, Ra and Sa in the nanofilled composite resin.

ABSTRACT

Abstract Objective There is increasingly common the consumption more times a day of foods and acidic drinks in the diet of the population. The present study aimed to evaluate and compare the effects of a calcium mesoporous silica nanoparticle single application of other calcium and/or fluoride products in reducing the progression of dental erosion. Methodology Half of the eroded area was covered of 60 blocks of enamel, after which the block was submitted to the following treatments: (Ca2+-MSN), casein phosphopeptide-amorphous calcium phosphate (CPP-ACP); CPP-ACP/F-(900 ppm F−); titanium tetrafluoride (TiF4 1%) (positive control); sodium fluoride (NaF 1.36%) (positive control); and Milli-Q® water (negative control) before being submitted to a second erosive challenge. A surface analysis was performed via a three-dimensional (3D) noncontact optical profilometry to assess the volumetric roughness (Sa) and tooth structure loss (TSL) and and through scanning electron microscopy (MEV). An analysis of variance (ANOVA) and Tukey's test were performed. Results Regarding Sa, all experimental groups exhibited less roughness than the control (p<0.05). The TSL analysis revealed that the Ca2+-MSN and NaF groups were similar (p>0.05) and more effective in minimizing tooth loss compared with the other groups (p<0.05). Conclusions The Ca2+-MSN and NaF treatments were superior compared with the others and the negative control.

ABSTRACT

Abstract This study aimed to evaluate adolescents' aesthetic perceptions and their social judgments regarding different enamel opacities. Sample size was calculated and resulted in the inclusion of 100 adolescents (aged 10 to 15 years) from a public school in Jequié, Bahia, Brazil. Images of enamel opacities were manipulated to create aesthetic enamel defects, such as enamel color changes (unilateral and bilateral white opacity, unilateral and bilateral yellowish opacity, and unilateral and bilateral yellowish opacity with loss of structure). The images of the opacities were based on Fédération Dentaire Internationale's Developmental Defects of Enamel (DDE) Index. Aesthetic perception and social judgments were evaluated using a validated questionnaire with 12 questions (six positive and six negative points) on social aspects, considering the six manipulated images and the control. The photographic analyses were projected one-by-one by computer to adolescents individually in a classroom. Participants had one minute to observe each image and answer the questionnaire. The data were analyzed by descriptions, and the Friedman Wilcoxon test (p < 0.05). The results indicate that all opacities negatively impacted social judgment (p < 0.001). The enamel aesthetic defects most affecting an individual's perception were bilateral yellow opacity with or without loss of structure (p < 0.001). Regarding social judgment, all participants showed a negative perception of all the tested opacity types (p < 0.001). In conclusion, even opacities presenting only a color change caused aesthetic dissatisfaction to the individuals and changes in their social judgment toward others. Color changes in dental enamel have several aesthetic consequences.

ABSTRACT

Abstract Here, the prevalence of oral candidiasis and denture stomatitis among diabetic patients compared to healthy ones was summarized through a systematic review with meta-analysis. Medline, Scopus, Web of Science, Lilacs, Cochrane Library, Embase, and the grey literature were searched without restriction, until May 2020. Eligibility criteria were established, data were extracted, and quality assessment was conducted by two trained examiners. Qualitative synthesis was based on the recommendations of Fowkes and Fulton. Two meta-analyses were performed on studies investigating patients with: a) oral candidiasis and b) denture stomatitis. Out of 6034 screened studies, seven were eligible for qualitative and quantitative synthesis; of these, three evaluated oral candidiasis and four evaluated denture stomatitis. Qualitative synthesis showed that the main methodological problems of the studies included sample size, source of controls, matching, and randomization. Diabetic patients had a similar chance of developing oral candidiasis to non-diabetic patients (OR1.40 [0.96; 2.04], p = 0.08, I2 = 94%). However, diabetic patients had a higher chance to present denture stomatitis compared to non-diabetic patients (OR 1.92 [1.42, 2.59] p < 0.0001, I2 = 0%). Therefore, diabetic patients have a higher chance of developing denture stomatitis compared to non-diabetic patients. However, for all analyses, the certainty of the evidence was considered to be very low.

ABSTRACT

Abstract The present study aimed to identify the scientific evidence regarding the association between crown discoloration and pulp necrosis in traumatized permanent teeth. A systematic literature search was conducted in the PubMed/Medline, Lilacs/BBO, Scopus, Web of Science, Cochrane Library databases, and grey literature. Quality assessment and bias control were carried out according to the Fowkes and Fulton guidelines. Meta-analysis was performed, and the odds ratio was calculated with a 95% confidence interval. The quality assessment of the evidence was determined for the meta-analysis outcomes using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. From 2,702 studies identified, five articles met the inclusion criteria. One among these showed no methodological soundness and was excluded from the meta-analysis, and the remaining four studies were included in the meta-analysis. The total number of traumatized permanent teeth evaluated in the meta-analysis was 367. The results showed a positive association between crown discoloration and pulp necrosis in permanent teeth. Teeth with crown discoloration showed 23 times more chance to present pulp necrosis than teeth without crown discoloration (OR 23.82 [1.25, 452.87]; p = 0.03), with a very low certainty of evidence. There is a significant association between crown discoloration and pulp necrosis of traumatized permanent teeth. Due to the very low strength of evidence according to GRADE, this result should be viewed with caution.

ABSTRACT

To evaluate the influence of mesofacial, brachyfacial and dolichofacial facial patterns on giving an individual the profile of a crime suspect in the eyes of public security agents.This study had a cross-sectional design, conducted with public security agents of both sexes (n=100), where images of facial composites (police sketches) of individuals with different facial patterns (mesofacial, brachyfacial and dolichofacial) were used. With these images in hand, a questionnaire was created, divided into three parts: the first in which all the images were presented together, allowing comparison among them; the second, in which each image was evaluated separately followed by questions and the third that consisted on a visual analog scale that presented a bar with marks going from 0 to 100, where 0 represented the untrustworthy individual, 50 the individual who could be trusted, and 100 a very trustworthy individual. When all the data had been obtained statistical analyses were performed using the Chi-square and Friedman tests. The level of significance adopted was 5% (α=0.05). The dolichofacial individual was associated with security agents as the most prone to commit crimes and became more insecure and distrustful when compared to the mesofacial and brachyfacial individuals (p <0.001). The dolichofacial profile had a negative influence on the judgment of security agents who attributed to it, a character suspected of a crime and a low level of trustworthiness


Avaliar a influência dos padrões faciais mesofacial, braquifacial e dolicofacial em conceder um perfil de suspeito a cometer crimes aos olhos dos agentes de segurança pública. Este estudo teve delineamento transversal, realizado com agentes de segurança pública de ambos os sexos (n = 100), onde imagens de retratos- falados de indivíduos com diferentes padrões faciais (mesofacial, braquifacial e dolicofacial) foram utilizadas. De posse dessas imagens, foi criado um questionário, dividido em três partes: a primeira em que todas as imagens foram apresentadas juntas, permitindo a comparação entre elas; a segunda, em que cada imagem foi avaliada separadamente seguida de perguntas e a terceira consistiu em uma escala analógica visual que apresentava uma barra com marcações de 0 a 100, onde 0 representava o indivíduo não confiável, 50 o indivíduo em quem se podia confiar, e 100 um indivíduo muito confiável. Após a obtenção dos dados, foram realizadas análises estatísticas utilizando os testes Qui-quadrado e Friedman. O nível de significância adotado foi de 5% (α = 0,05). O indivíduo dolicofacial foi associado pelos agentes de segurança como o mais propenso a cometer crimes e passou mais insegurança e desconfiança, quando comparado aos indivíduos mesofacial e braquifacial (p<0,001). O perfil dolicofacial influenciou negativamente no julgamento dos agentes de segurança que atribuíram-lhe caráter suspeito a cometer crimes e baixo grau de confiabilidade.

ABSTRACT

Introduction: Children presents high prevalence of traumatic dental injury (TDI). Objective: It is very important to detect the impact on oral health related to quality of life (OHRQoL) in this age group. Methods: Based on this, a cross sectional study was carried out using a convenience sample. Children from 8-10 years with TDI in permanent teeth were recruited over an 18 month period, from a public University. Data about OHRQoL using the Brazilian version of CPQ 8-10 (B-CPQ 8- 0 ) were collected. TDI were classified according to Andreasen criteria and grouped according to its severity. Variations in the scores and impact of TDI on OHRQoL according to age, gender and TDI severity were examined using nonparametric statistical tests (Kruskall-Wallis and Mann-Whitney test, p<0.05). Results: From a sample of 255 children, 41 healthy children that suffered TDI in permanent were included in the study. The mean B-CPQ 8-10 scores were 29.7 (SD 14.3). Emotional and social wellbeing domais had the highest negative score impact average 8.8 (SD 5.9) and 9.8 (SD 6.3), respectively. Gender or TDI severity did not present relation to impact on OHRQoL. In relation to age, 10-year-old children had more impact on their OHRQoL on the overall scale (p<0.05) and for the functional limitation subscale (p<0.05). Conclusion: TDI impacts negatively on OHRQoL of children aged from 8-10 years old.


Introdução: Crianças apresentam alta prevalência de traumatismo dentário (TD).Objetivo: Detectar o impacto do TD na qualidade de vida relacionada à saúde bucal (QVRSB) nessa faixa etária. Métodos: Um estudo transversal foi realizado com amostra de conveniência recrutando-se crianças de 8-10 anos com TD em dente permanente por um período de 18 meses em clínica pública. Dados sobre a QVRSB foram coletados através da versão brasileira do CPQ 8-10 (B-CPQ 8-10 ). O TD foi classificado de acordo com os critérios de Andreasen e agrupado de acordo com sua gravidade. As variações nos escores e o impacto do TD na QVRSB, de acordo com idade, gênero e gravidade do TD foram examinados por meio de testes estatísticos não paramétricos (teste de Kruskall-Wallis e Mann-Whitney, p <0,05). Resultados: De uma amostra de 255 crianças, 41 crianças saudáveis que sofreram TD em dentes permanentes foram incluídas no estudo. O escore médio do B-CPQ 8-10 foi 29,7 (DP 14,3). Os domínios bem-estar emocional e social apresentaram maior impacto negativo com média de 8,8 (DP 5,9) e 9,8 (DP 6,3), respectivamente. A diferença de gênero e a gravidade do TD não apresentaram relação de impacto na QVRSB. Em relação a idade, crianças de 10 anos tiveram maior impacto na escala global da QVRSB (p <0,05) e na subescala de limitação funcional (p <0,05). Conclusão: O TD impacta negativamente a QVRSB de crianças de 8 a 10 anos de idade.
