RESUMO
OBJECTIVE: To systematically review the literature regarding the concordance of sleep bruxism (SB) between monozygotic (MZ) and dizygotic (DZ) twins. METHODS: The registration for this systematic review was accomplished in the International Prospective Register of Systematic Reviews (PROSPERO, No. CRD42021251751). As of July 2022, four databases were searched, including PubMed, Scopus, Embase, and Web of Science, as well as the grey literature in Google Scholar and OpenGrey. Observational studies evaluating SB in MZ and DZ twins of any age and sex were included. For the evaluation of the risk of bias, the Joanna Briggs checklist was utilized. The certainty of evidence was assessed via the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. Pooled and subgroup meta-analyses were performed to estimate concordance of SB ââbetween twins (p < 0.05). RESULTS: In total, 3,155 records were identified. In the qualitative analysis, eleven studies were included; of these, seven were included in the meta-analysis. The majority of the articles exhibited a low risk of bias (63.6%). Greater SB concordance was observed between MZ twins than between DZ twins in the analysis of general concordance (OR = 1.47; 95% CI = 1.07-2.02) and also positive concordance (OR = 1.53; 95% CI = 1.29-1.81). Within the subgroup analyses, the significance of the findings remained only for the reported/self-reported SB regarding general concordance (OR = 1.44; 95% CI = 1.07-1.95) and positive concordance (OR = 1.55; 95% CI = 1.28-1.88). Low certainty of the evidence was observed for the general concordance analysis, while moderate certainty was observed for the positive concordance. CONCLUSION: There was a higher concordance of SB in MZ twins compared to DZ twins, indicating a possible genetic influence on the condition's occurrence.
RESUMO
BACKGROUND: Important evidence has been constantly produced and needs to be converted into practice. Professional consumption of such evidence may be a barrier to its implementation. Then, effective implementation of evidence-based interventions in clinical practice leans on the understanding of how professionals value attributes when choosing between options for dental care, permitting to guide this implementation process by maximizing strengthens and minimizing barriers related to that. METHODS: This is part of a broader project investigating the potential of incorporating scientific evidence into clinical practice and public policy recommendations and guidelines, identifying strengths and barriers in such an implementation process. The present research protocol comprises a Discrete Choice Experiment (DCE) from the Brazilian oral health professionals' perspective, aiming to assess how different factors are associated with professional decision-making in dental care, including the role of scientific evidence. Different choice sets will be developed, either focusing on understanding the role of scientific evidence in the professional decision-making process or on understanding specific attributes associated with different interventions recently tested in randomized clinical trials and available as newly produced scientific evidence to be used in clinical practice. DISCUSSION: Translating research into practice usually requires time and effort. Shortening this process may be useful for faster incorporation into clinical practice and beneficial to the population. Understanding the context and professionals' decision-making preferences is crucial to designing more effective implementation and/or educational initiatives. Ultimately, we expect to design an efficient implementation strategy that overcomes threats and potential opportunities identified during the DCEs, creating a customized structure for dental professionals.

AIM: To assess the impact of outpatient dental treatment on oral health-related quality of life (OHRQoL) of children and their families. MATERIALS AND METHODS: This prospective observational study was conducted with children with untreated dental caries, recruited from a public university/the pediatric dentistry clinic of a public university in the northeastern Brazil. Sociodemographic data were collected, a clinical examination was carried out before and after dental treatment, and the Early Childhood Oral Health Impact Scale (ECOHIS) questionnaire was applied to those responsible for the children, before and after dental treatment. Descriptive and bivariate statistics were used, and the Wilcoxon and Student's t tests were applied (p < 0.05). RESULTS: The study included 64 children, of both sexes, aged between 3 and 5 years old. The majority had a dmft index higher than or equal to 6 (60.9%), with a mean value of 7.11 (± 4.11). Sociodemographic conditions such as sex, age, and socioeconomic status had no impact on their OHRQoL (p > 0.05). The mean total ECOHIS questionnaire scores and those of its domains decreased after completion of the treatments (p < 0.05), except for scores in the self-image and distress domains of the parents (p > 0.05). This study reinforces the relevance of adopting oral health policies aimed at the prevention and treatment of ECC. CONCLUSION: Outpatient dental treatment had a positive impact on the OHRQoL of children and their families. CLINICAL RELEVANCE: The possibility of evaluating the services provided by the pediatric dentistry clinic.

BACKGROUND: Hypomineralised second primary molar (HSPM) is a developmental enamel defect associated with dental caries. AIM: To evaluate the impact of HSPM on oral health-related quality of life (OHRQoL) in preschoolers through hierarchical analysis. DESIGN: This population-based cross-sectional study assessed 834 5-year-old preschoolers, in Teresina, Piauí, Brazil, using sociodemographic questionnaires and Early Childhood Oral Health Impact Scale (ECOHIS). Dental examination was performed by two calibrated examiners (κ ≥ 0.80) for the diagnosis of HSPM (EAPD), dental caries (dmft and pufa indices), and malocclusion (Foster and Hamilton criteria). Analysis of the determinants of OHRQoL was stratified at three levels (P < .05). RESULTS: Severe HSPM was associated with OHRQoL in bivariate analysis (P < .05). In adjusted final multivariate analysis (model 1), the presence of dental caries with or without clinical consequences was associated with worse OHRQoL (P < .05). In model 2, after the removal of dental caries, preschoolers with severe HSPM had greater probability of having a negative impact on OHRQoL in the child impact section (RR = 2.14; 95% CI = 1.26-3.65), family impact section (RR = 1.99; 95% CI = 1.16-3.42), and total score (RR = 2.09; 95% CI = 1.25-3.49) of the ECOHIS. CONCLUSION: Severe HSPM had a negative impact on the OHRQoL of preschoolers and their families, but the presence of dental caries neutralised this impact.

PURPOSE: To determine the prevalence of probable sleep bruxism (SB) in preschoolers and associated factors. METHODS: A cross-sectional, population-based study was carried out with 862 dyads of parents/preschoolers aged 5 from Teresina, Brazil. Data collection was performed through a questionnaire answered by parents/guardians about socioeconomic, demographic, and health condition data. Each child was examined for diagnosis of probable SB based on the presence of dental wear associated or not with the report of teeth grinding by parents/guardians. The analysis of independent variables was stratified into four levels of determinants: demographic characteristics of the child (distal), characteristics of the family, environmental factors (intermediate), and health conditions (proximal). Descriptive analysis and bivariate and multivariate Poisson's regression were performed using a hierarchical approach (p < 0.05). RESULTS: The prevalence of probable SB was 36%. In the final adjusted multivariate hierarchical model, a preschooler who was the only child (PR = 1.25; 95%CI = 1.02-1.51), with breathing problems (PR = 1.43; 95%CI = 1.19-1.73), and having parents/guardians with possible sleep bruxism (PR = 1.65; 95%CI = 1.32-2.07) had a higher prevalence of probable SB. CONCLUSION: The prevalence of probable SB in preschoolers was high and associated with the condition of being an only child, the presence of breathing problems, and having parents/guardians with possible sleep bruxism.

The oromandibular limb hypogenesis syndromes (OLHS) represent a group of rare conditions characterized by congenital malformations involving the tongue, mandible, and limbs. In this report, we describe a newborn girl with paralysis of abducens and facial nerves, transverse agenesis of the distal segments of the limbs, micrognathia, cleft lip and palate, and ankyloglossia superior. This observation confirms an overlap between Moebius syndrome and ankyloglossia superior syndrome with severe limb defects. The etiology of the OLHS is not clearly understood. The intriguing link between facial and limb anomalies can result from their simultaneous development from the fourth to eighth week of gestation, making both areas susceptible to the same teratogenic stimuli. There is an overlap between OLHS conditions, supporting a clustering, rather than a divided nosology and requiring an appropriate classification of these conditions. Patients with OLHS can be successfully managed using a multidisciplinary approach.

BACKGROUND: Hypomineralized second primary molar (HSPM) is a developmental enamel defect that represents a caries-risk factor. There are few studies about HSPM epidemiology in representative populations. AIM: To determine the prevalence and factors associated with HSPM in pre-schoolers. DESIGN: This is a cross-sectional population-based study of 5-year-old pre-schoolers from Teresina, Brazil. The sample was randomly selected and stratified by geographic region of the city, type of school (public and private), and sex of the pre-schoolers (n = 811). Sociodemographic status and pre-, peri-, and post-natal conditions were collected by structured questionnaires. Two calibrated examiners diagnosed HSPM using the criteria of the European Academy of Paediatric Dentistry for molar-incisor hypomineralization. Severity, colour, location, and extent of lesions were also evaluated. Descriptive analysis of the data and a Poisson regression analysis were performed (P < .05). RESULTS: The prevalence of HSPM was 14.9. Demarcated opacities (75.6%) and white/cream colour were the most prevalent (71.4%). Pre-term pre-schoolers had 66% (PR = 1.66, 95% CI = 1.07-2.58), and those who reported asthma in the first year of life had 69% (PR = 1.69, 95% CI = 1.01-2.85) higher prevalence of HSPM. CONCLUSIONS: Pre-term birth and reported asthma in the first year of life were associated with HSPM. The prevalence of HSPM in pre-schoolers aged 5 years old in Teresina was high.

OBJECTIVE: To observe if dental alterations in premolars are associated with the rupture of the follicle bone crypt caused by a periapical lesion in the predecessor molars. STUDY DESIGN: This is a cross-sectional study. Data collection consisted of the analysis of medical records, a socioeconomic questionnaire, and dental clinical examination. Records from patients with a history of a radiographically visible periapical lesion in lower primary molars submitted to pulp therapy or extraction from a university dental clinic were selected. Successor premolars were clinically evaluated for the presence of enamel development defects, shape alterations, and eruption deviations. The descriptive analysis of data was performed, and Fisher's exact tests, linear trend chi-square, and the Student's t-test were applied. RESULTS: Forty-eight permanent teeth were from 36 patients were evaluated in this study, and 20 (41.7%) of the 48 examined premolars showed a radiographic image suggestive of the rupture of the bone crypt. Rupture of the follicle bone crypt was not associated with the occurrence of enamel alterations in premolars (p = 0.418). An association between dental alterations and age over six years at the time of intervention was observed (p = 0.043). CONCLUSION: The presence of enamel alterations of premolars was not associated with the rupture of the follicle bone crypt caused by a periapical lesion in predecessor molars.

BACKGROUND: Developmental enamel defects (DDE) represent one of the prevalent oral problems in childhood; however, few studies have evaluated its impact on quality of life in the children's own perception. AIM: To evaluate the DDE impact on quality of life of 5-year-old children. METHODS: This cross-sectional observational study assessed 566 children aged 5 years old, in Teresina, Piauí, Brazil, according to their self-perceptions. Children answered the Pediatric Quality of Life Inventory™ Version 4.0 and Oral Health Scale. The dmft index, modified DDE index and Foster and Hamilton criteria were used to diagnose dental caries, DDE and malocclusion, respectively. A single examiner performed the clinical examination. Descriptive analyses and Poisson regression with robust variance were performed. RESULTS: The prevalence of DDE was 33.7%. For children's self-reports, the presence of DDE had a negative association with oral health-related quality of life (OHRQoL; PR 1.09, 95% CI 1.02-1.15). Enamel hypoplasia had a negative impact on the physical function (PR 1.05; 95% CI 1.01-1.10) and oral health (PR 1.06, 95% CI 1.01-1.11) domains. Diffuse opacity had a negative impact on the social aspect (PR 1.09, 95% CI 1.02-1.18). CONCLUSIONS: Enamel defects had a negative impact on OHRQoL according to the self-reports of the children.

The interradicular region of primary molars is permeated by many foramina, channels and accessories that connect the pulp cavity with the periapical tissues anatomically. Thus, pulp decomposition products or drugs used in endodontic treatment can trigger inflammatory reactions. The aim of this study was to evaluate the blood cell profile of the alveolar region after extraction of primary molars treated with CTZ paste. Forty-eight primary molars were selected with clinical and radiographic signs of extraction. The sample was divided into three groups with 16 teeth each: Group 1-healthy teeth; Group 2-untreated decayed teeth; and Group 3-teeth treated with CTZ paste. Immediately after the extraction, blood from the interface of the tooth socket was collected and smears were performed for further evaluation. The slides were stained by the Fast Panoptic® method and analysed by two previously trained examiners who counted the leucocytes in sets of 100 cells/slide, differentiating them into neutrophils, lymphocytes, monocytes, eosinophils and basophils. The data were analysed statistically by the MANOVA test. The blood samples from Group 2 differed significantly from Group 1 samples for all classes of leucocytes, except basophils, with higher average for lymphocytes (62.56), monocytes (7.81) and eosinophils (2.31). For Group 3, there was a relative difference (P < 0.05) to Group 2, of monocytes and eosinophils values. The blood cellularity interface in the tooth socket of primary teeth treated with CTZ paste is similar to those of healthy, exfoliated teeth and physiologically different from untreated decayed teeth.

BACKGROUND: The etiology of molar-incisor hypomineralization (MIH) remains unknown. Studies indicate that it is multifactorial, and that genetic and environmental factors are involved. Research with twins provides important subsidy to investigate the Influence of genetics and environmental factors that act during pregnancy on the etiology of alterations. AIM: This cross-sectional study evaluated the agreement of molar incisor hypomineralization (MIH) between monozygotic and dizygotic twin pairs and the association with environmental factors. DESIGN: The sample consisted of 167 pairs of twins (8-15 years old), 94 monozygotic and 73 dizygotic. The parents answered a questionnaire on sociodemographic data and pre-, peri-, and postnatal health. A dental examination was performed by two calibrated examiners (Kappa ≥0.88) for MIH diagnosis, following the criteria proposed by the European Academy of Pediatric Dentistry in 2003. RESULTS: The prevalence of MIH was 29.3%. There was greater concordance of MIH between monozygotic twins for affected first molars and permanent incisors (P = 0.0012) and pairs of twins assessed (P = 0.0211). The presence of MIH was associated with family income between one and two wages (P = 0.009, prevalence ratio [PR] = 3.82, confidence interval [CI 95%] 1.40-10.44), above two wages (P = 0.007, PR = 4.60, 95% CI: 1.51-14.05), and gestational hemorrhage (P = 0.032, PR = 5.70, 95% CI: 1.16-28.14). CONCLUSIONS: The greater concordance in the diagnosis of MIH among monozygotic twins indicates a genetic influence, although environmental factors, such as family income and hemorrhage during pregnancy, are also associated with the occurrence of MIH.

OBJECTIVE: This study presents 38 cases of primary molars with necrotic pulps treated with antibiotics-based paste. CASE REPORT: The technique consisted of necrotic tissue removal of the pulp chamber, using spoons excavators and low speed drills. Pulp cavity was washed with saline solution and dried with sterile cotton balls. Then an antibiotic paste composed of chloramphenicol, tetracycline, zinc oxide and eugenol - CTZ paste - was inserted at the entrance of root canals. Patients were evaluated clinically and radiographically at different times. The criteria that defined clinical success were the lack of periapical abscess and mobility compatible with chronological age. Radiographic assessments consisted in absence of radiolucency in the region of root bifurcation and pathological bone resorption. CONCLUSION: There were 100% and 93% of clinical and radiographic success, respectively. The results suggest that the CTZ paste is an optional therapy for pulp of primary molars.

The main sources of fluoride intake by children are fluoridated water and toothpaste. Little has been studied regarding fluoride intake from these sources in regions with tropical climates and high temperatures throughout the year. This study aimed to determine the amount of fluoride ingested from diet and tooth brushing by children who live in a city with a tropical climate. Sixty-seven children from Teresina, Piauí, Brazil, took part in this study. The city's water supply was optimally fluoridated. The duplicate-diet method was used to determine the fluoride intake from diet. The intake of fluoride from dentifrice was determined by subtracting the amount of fluoride placed on the toothbrush and that recovered after brushing. The concentration of fluoride was measured using an ion-specific electrode and is expressed as milligrams/kilogram of body weight/day. The mean (±SD) total amount was 0.071 ± 0.036 mg F/kg body weight/day, and the relative contributions of diet and toothpaste were 0.025 ± 0.010 and 0.046 ± 0.035, respectively. The factors associated with fluoride intake from toothpaste were: use of children's toothpaste (p = 0.003), use of large amounts of toothpaste (p < 0.001), and a high frequency of tooth brushing (p = 0.003). Sixty-four percent of children had an intake of less than 0.07 mg F/kg body weight/day, which is considered the upper limit for an aesthetically tolerable fluorosis risk. The results suggest that the amount of fluoride ingested by most children who live in a Brazilian city with a tropical climate is considered safe in terms of the risk of dental fluorosis.

The aim of the study was to evaluate salivary fluoride (F) availability after toothbrushing with a high-F dentifrice. Twelve adult volunteers took part in this crossover and blind study. F concentration in saliva was determined after brushing with a high-F dentifrice (5000 µg F/g) or with a conventional F concentration dentifrice (1100 µg F/g) followed by a 15 mL distilled water rinse. Samples of nonstimulated saliva were collected on the following times: before (baseline), and immediately after spit (time = 0) and after 1, 2, 3, 4, 5, 10, 15, 20, 30, 45, 60, 90, and 120 min. F analysis was performed with a fluoride-sensitive electrode and the area under curve of F salivary concentration × time (µg F/mL × min(-1)) was calculated. At baseline, no significant difference was found among dentifrices (P > 0.05). After brushing, both dentifrices caused an elevated fluoride level in saliva; however salivary F concentration was significantly higher at all times, when high-F dentifrice was used (P < 0.01). Even after 120 min, salivary F concentration was still higher than the baseline values for both dentifrices (P < 0.001). High-F dentifrice enhanced the bioavailability of salivary F, being an option for caries management in patients with high caries risk.

A 12-year-old boy presented for dental care 35 days after he fell from his bicycle. Clinical and radiographic examinations revealed a longitudinal crown-root fracture with pulp exposure in the maxillary left central incisor. The radiograph also suggested necrosis of the maxillary right central incisor. Urgent treatment of the left central incisor involved gingivectomy followed by autogenous bonding of the tooth fragment with self-curing composite resin. Immediately after bonding, coronal access was prepared, chemical and mechanical preparation was completed, and a calcium hydroxide intracanal dressing was placed. One week after the initial appointment, endodontic treatment was initiated in the right central incisor. The root canal of the maxillary left central incisor was maintained with calcium hydroxide paste (replaced at 45-day intervals) for 1 year and then definitively obturated. At the 16-year follow-up, satisfactory periodontal, esthetic, and clinical conditions were observed, and a radiograph revealed no resorption or periapical changes.

Fracture of the anterior teeth by trauma is the most frequent type of injury affecting the permanent dentition, especially the maxillary central incisors. When the fragment is not available or its use is not recommended, donated extracted teeth (homogenous bonding) can be used. The aim of this paper is to report the successful 18-year follow up of a maxillary central incisor fracture in which homogenous bonding was performed.

Among injuries that affect permanent teeth, the most prevalent is an uncomplicated crown fracture. Currently, autogenous bonding of the fragments is still the procedure of choice to restore fractured anterior teeth if the fragments are recovered by the patient and taken to a dental office within a reasonable time in an appropriate storage medium. There is no study or case report in the literature regarding autogenous bonding of lower incisors. This study presents a case with a 17-year follow-up for a 9-year-old patient who underwent uncomplicated crown fractures of the permanent mandibular central incisors and was treated by autogenous bonding of the tooth fragments. After 17 years, clinical and radiographic dental elements present vitality, and the restorations remain without major cosmetic changes. This case shows that autogenous bonding can be considered as a treatment option in the management of fractured lower incisors.

INTRODUCTION: Knowledge of bibliometric indices on the avulsion of permanent teeth can help researchers to identify gaps in the literature. The aim of this study was to analyze the bibliometric characteristics of the 100 most-cited articles on the avulsion of permanent teeth. MATERIALS AND METHODS: Two researchers conducted an unfiltered search in the Core Collection section of the Web of Science (WoS-CC) database. The following data were extracted: position in the citation list, total number and density of citations, title, authors, institution, country, year of publication, journal, keywords, study design, tooth storage medium, and other topics of interest. Bibliometric networks were generated and analyzed using the VOSviewer software. Descriptive analysis and a Poisson regression analysis were performed (P < .05). RESULTS: The number of citations per article varied between 31 and 407. The average was 70.05, and 13 articles received more than 100 citations. J.O. Andreasen (n = 13) and M. Trope (n = 15) were the authors who contributed most often to publications. The United States was the country with the highest number of articles (n = 31). Authors associated with the University of Copenhagen, Denmark (n = 9) and University of North Carolina, USA (n = 10) showed higher productivity. In vitro/animal model studies were the most frequent study designs (n = 50), and the most-discussed topic of interest was prognosis (n = 47). There was strong clustering among 13 research groups. CONCLUSION: Observational studies, published by authors from Europe and about prognosis or treatment presented more citation ratio in WoS-CC. Clinical studies on permanent tooth avulsion are needed to increase the quality of scientific evidence and provide insights for health professionals and public policy makers.
