RESUMO

OBJECTIVES: This systematic review aimed to determine the pooled prevalence of toothache in children and adolescents and to verify its association with sociodemographic characteristics and dental caries experience. MATERIAL AND METHODS: Six main and three grey literature databases were searched in February 2021. Observational studies that assessed the prevalence of toothache and associated factors were included. The methodological quality of the studies was evaluated following the guidelines by Fowkes and Fulton. Proportion and association meta-analyses were performed in MedCalc and Revman software, respectively. The certainty of the evidence was determined with the GRADE approach. RESULTS: Seventy-one studies met the inclusion criteria. Thirty-two presented high methodological quality and a low risk of bias. The overall pooled prevalence of toothache in children and adolescents was 36.2% (95%CI: 33.0-39.42; I2: 99.72%; P < 0.001). Females (OR: 1.17; 95%CI: 1.08-1.26; I2: 91%; P < 0.001) and children and adolescents whose caregivers had ≤ 8 years of schooling (OR: 1.42; 95%CI: 1.30-1.56; I2: 77%; P < 0.001) presented the higher chance of reporting toothache. Dental caries experience increased the chance of reporting toothache in 3.49 times (95%CI: 2.70-4.51; I2: 92%; P < 0.001). The certainty of the evidence was very low. CONCLUSIONS: The overall pooled prevalence of toothache was considered high. Sociodemographic characteristics (sex and caregivers' educational level) and previous dental caries experience were significantly associated with toothache reports. CLINICAL RELEVANCE: Toothache is still a recurrent issue in many countries. Thus, it is essential to understand its possible associated factors to reduce the occurrence of new episodes.

RESUMO

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

Premature loss of primary anterior teeth in deciduous arches is a controversial topic in the literature, especially due to the lack of robust scientific evidence regarding the types and magnitudes of the consequences involved. Morphological, functional, and psychosocial problems may arise from untreated premature loss of primary incisors and canines. The morphological problems include impaction and eruption disturbances of permanent successors; inclination and/or extrusion of adjacent and antagonist teeth, respectively; midline deviation; and crowding. Functional complications, such as speech disorders, aesthetic problems, and development of non-nutritive habits may occur, resulting in psychosocial implications, including a decrease in self-esteem, and even being targeted for bullying. The current critical review aimed to present and discuss the evidence available in the literature about the etiology, characteristics, implications and interventions resulting from the premature loss of primary anterior teeth. It is of utmost importance that future studies be developed to support the clinical decisions made by dental professionals on this topic.

RESUMO

To evaluate the knowledge of Brazilian dentists of sports doping through the development, validation and application of the Brazilian Knowledge Scale about Sports Doping in Dentistry (B-KSSDD). A scale with 12 items was developed to assess a dentist's ability to determine whether the use of a medication characterised sports doping according to the World Anti-Doping Agency. A preliminary study to validate the B-KSSDD was carried out with 135 dentists, allowing the evaluation of ceiling and floor effects, convergent and discriminant validity, test-retest reliability and internal consistency of the instrument. A sample size calculation using the results of the preliminary study and the B-KSSDD was completed online using SurveyMonkey® by 270 participants from all regions of the country. The B-KSSDD showed evidence of convergent and discriminant validity, good temporal stability (ICC = 0.75) and internal consistency (alpha = 0.89). In the main study, the participants obtained an average score of 4.19/12 points on the B-KSSDD, suggesting that these professionals have insufficient knowledge about sports doping. The age of participants showed a negative association with knowledge about doping, while frequency of treating athletes and frequency of performing surgeries showed positive associations with knowledge about doping. The dentists had insufficient knowledge of the subject. Age of participants and frequency with which they attend to athletes are associated with knowledge about sports doping. Professional updating and education policies on doping are necessary for dentists, as athlete patients are at risk for severe sporting and financial penalties.

RESUMO

OBJECTIVES: Assessing the evidence and comparing the levels of cytokines in gingival crevicular fluid (GCF) of periodontal healthy sites of smokers and nonsmokers. MATERIALS AND METHODS: Seven databases were surveyed for observational studies up to April 8, 2021. Studies comparing cytokine levels on GCF in periodontally healthy sites of smokers vs. nonsmokers were included in the study. The risk of bias was evaluated using NIH (2014) tool. For meta-analyses, levels in GCF were analyzed, followed by evidence certainty assessment using the GRADE approach. RESULTS: Eighteen studies were included for qualitative evaluation, and eight were included in meta-analysis. Qualitatively, despite high heterogeneity and risk of bias observed among the studies, most of them presented no significant difference in the gingival crevicular cytokine fluid levels between groups. Regarding meta-analyses, interleukin-8 (IL-8) and superoxide dismutase (SOD) levels in GCF were analyzed. The significant difference was observed only in SOD levels, where heavy smokers had lower levels compared to nonsmokers (MD - 30.06 [- 40.17, - 19.96], p = 0.07, 95%CI), as well as light smokers had lower levels compared to nonsmokers (MD - 15.22 [- 16.05, - 14.39], p < 0.00001, 95%CI). CONCLUSION: No distinct GCF cytokine profiles were detected for smokers and non-smokers. However, despite the limitations observed in the included studies, lower levels of SOD were identified in smokers. CLINICAL RELEVANCE: Indicating a distinct GCF profile of cytokines in periodontal healthy smokers may help to understand the mechanism whereby smoking may affect the host response.

RESUMO

STATEMENT OF PROBLEM: Denture adhesives improve the mastication of complete denture wearers. However, the impact of denture adhesives with different presentations on mastication remains unclear. PURPOSE: The purpose of this systematic review was to answer the focused question, "Do different presentations of denture adhesives affect the masticatory function of complete denture wearers?". MATERIAL AND METHODS: This review was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Six databases and the non-peer-reviewed literature were searched up to July 2021. Only clinical studies (randomized clinical trials and nonrandomized clinical trials) comparing the use of different denture adhesive presentations (cream, powder, or strips) were included, without language or follow-up restrictions. The risk of bias was assessed by using the Cochrane tools (RoB 2.0 and ROBINS-I). Masticatory performance, by using single and multiple sieves, masticatory performance with color-changing chewing gum (mixing ability), swallowing threshold (particle size and number of cycles), jaw kinematics, and occlusal force were considered. Meta-analyses were conducted to evaluate masticatory performance (single sieve) and occlusal force outcomes (α=.05), and the certainty of the evidence was determined with the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) evaluations. RESULTS: Nine studies (6 randomized and 3 nonrandomized clinical trials) were included. The risk of bias was considered moderate. Meta-analyses showed no differences between cream and powder denture adhesives for masticatory performance (standard mean difference=0.02; 95% CI=-0.46 to 0.50, P=.93) or between cream and strip denture adhesives for occlusal force (mean difference=14.35; 95% CI=-11.14 to 39.84, P=.27). Similarly, in qualitative analysis, cream and powder denture adhesives' performances were similar regarding masticatory performance with color-changing chewing gum (mixing ability), occlusal force, swallowing threshold (particle size and number of cycles), and jaw kinematics (P>.05). However, for resorbed ridges, cream denture adhesive resulted in a higher masticatory performance than strip (P<.05). When comparing powder to strip denture adhesives, the occlusal force was higher in the powder group (P<.05). The certainty of evidence was very low for all evaluated outcomes. CONCLUSIONS: Different presentations of denture adhesives seem to improve the masticatory function of complete denture wearers in a similar way. However, the qualitative analysis showed that, in patients with a resorbed ridge, a cream denture adhesive may be better than strips to improve mastication, although the certainty of evidence was very low.

RESUMO

BACKGROUND/AIMS: Traumatic dental injuries (TDI) are a public health problem and the search for information becomes essential to help in their management. The aim of this study was to search existing TDI applications (Apps) to critically describe the characteristics and main information found in them regarding TDI. METHODOLOGY: Searches were performed in the Play Store (Android) and App Store (iOS), using MeSH terms, synonyms and terms related to dental emergencies and TDI, in English, Spanish and Portuguese. Apps with information on the management of post-TDI emergencies or TDI prevention were included. The type of operating system (Android/iOS), cost (free/paid), target audience (dentist/patient), age of classification (free/>17 years old), language, star rating (1★ to 5★), number of downloads and post-download ratings, type of dentition (primary/permanent), reference used for classification according to TDI type and management (International Association for Dental Traumatology/Andreasen/others/not reported), and available content (prevention/emergency management/preservation/illustrations) were evaluated. RESULTS: Among 486 apps, 13 were eligible: 11 for Android and 2 for iOS. Most were free (92.3%), for patients (38.4%) and had a free age classification (90.9%). The main language was English (53.8%), and most of the Apps either had no information on star ratings (46.1%) or received 4★ (23.1%). The number of downloads was not reported (23.1%) or was fewer than 100 (23.1%). Most of the Apps were for permanent teeth (61.5%) and had explanations about dental management for TDI emergencies (92.3%) and multiple TDIs (61.5%). Most Apps addressed the importance of monitoring TDIs (76.9%) and contained illustrative images (76.9%). However, many did not report the TDI classification (46.1%), and 38.5% reported TDI prevention. CONCLUSIONS: Information on dental trauma management according to dental injury, inclusion of images, target audience, type of TDI and their prevention varied in the available Apps. However, most were focused on permanent teeth and addressed several TDI in English language only.

RESUMO

INTRODUCTION: This trial aimed to longitudinally evaluate the effect of the treatment of transverse maxillary deficiency using rapid palatal expansion (RPE) on self-perceived oral health-related quality of life (OHRQOL) in children. METHODS: Eighty participants aged 8-10 years with transverse maxillary deficiency and bilateral posterior crossbite were randomly assigned to 2 groups (n = 40 each): a group treated with RPE using hyrax-type appliances and a nontreated control group. OHRQOL was assessed by using the Child Perceptions Questionnaire for 8-10-year-olds at 4 times: before RPE, during RPE (T1), at the end of RPE (T2), and 1 month after the appliance removal (T3). Generalized mixed models were used for data analysis (α = 0.05). RESULTS: Both groups exhibited similar demographic characteristics and OHRQOL scores at baseline. All participants completed the study. RPE had a time-dependent effect on OHRQOL. At T1 and T2, this therapy is expected to increase the overall OHRQOL scores by 1.17 times (ie, ∼17% increase; T1 95% confidence interval [CI], 1.08-1.26; T2 95% CI, 1.09-1.27; P = 0.001). In contrast, the overall OHRQOL scores at T3 are expected to be 0.28 times the baseline scores (ie, ∼72% reduction; T3 95% CI, 0.26-0.31; P = 0.001). All individual domains of the OHRQOL evidenced a positive impact of treatment at T3 (P = 0.001). Only the oral symptoms and social well-being domains showed a significantly negative impact of the treatment at T1 and T2. CONCLUSIONS: Correction of the transverse maxillary deficiency by RPE in children aged 8-10 years improves OHRQOL. There is a temporary worsening of OHRQOL during the treatment of this condition using RPE. REGISTRATION: This trial was not registered. PROTOCOL: The protocol was not published before trial commencement. FUNDING: This study was financed by the Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - Brazil, Financing Code 001.

RESUMO

Periodontitis is a multifactorial disease triggered by dysbiotic biofilms, involving the host's immune response, systemic and behavioral factors, including psychosocial conditions. This systematic review aimed to investigate the possible association between periodontitis and anxiety in adults. Searches were performed in PubMed, Scopus, Web of Science, Lilacs, Cochrane, and OpenGrey databases, without language restrictions, considering studies in adults (P-Participants), with (E-Exposure) and without periodontitis (C- Comparison) in an outcome of association with anxiety (O-outcome). Methodological quality assessment was carried out using the Newcastle-Ottawa protocol for case-control and cross-sectional studies, followed by an analysis of the level of evidence using the GRADE tool. Metanalysis was not performed due to several differences in methods applied by authors in primary studies. Eleven observational studies were selected according to the inclusion criteria from the total of 6,380 studies retrieved from databases. Eight studies demonstrated higher anxiety levels in subjects with periodontitis, among which only one study presented a high risk of bias. The GRADE tool revealed a low level of evidence for the anxiety outcome measured by the State-Trait Anxiety Inventory (STAI), both for case-control and cross-sectional studies. However, since anxiety may affect the quality of life of many subjects, it reinforces the need for further studies that evaluate this association for more extended periods. Clinical Trial Registration:PROSPERO-CRD42020190445.

RESUMO

This study evaluated the antimicrobial activity of root canal filling pastes commonly used in primary teeth: iodoform paste, zinc oxide-eugenol (ZOE), and analytical grade calcium hydroxide (Ca[OH]2). The materials were evaluated in the following 6 combinations: iodoform paste (Rifocort [prednisolone + rifampicin] + iodoform + camphorated paramonochlorophenol); zinc oxide + eugenol in a proportion of 1:3; zinc oxide + eugenol in a proportion of 1:5; Ca(OH)2 + water; iodoform paste + ZOE (1:3) + Ca(OH)2; and ZOE (1:3) + Ca(OH)2. Chlorhexidine gel (0.2%) served as the positive control. A commercial strain of Enterococcus faecalis (ATCC 25175) was plated in petri dishes containing 10 mL of brain-heart infusion agar culture medium with a hole in the center. The filling pastes (3 g) were manipulated and inserted in the hole. The plates were incubated at 37°C for 48 hours, and then the inhibition zone associated with each paste was measured. The experiments were carried out in triplicate (n = 3 per group). The data were submitted to analysis of variance and Tukey tests (P < 0.05). Iodoform paste resulted in the largest mean (SD) inhibition zone, 7.06 (0.74) mm. The smallest was obtained with Ca(OH)2 + water, the mean (SD) of 0.00 (0.00) mm indicating that these specimens did not form an inhibition zone. The ZOE pastes in proportions of 1:3 and 1:5 resulted in statistically similar mean (SD) inhibition zones of 1.86 (0.50) and 1.30 (0.18) mm, respectively (P > 0.05). Of the test materials, the combination of iodoform paste + ZOE + Ca(OH)2 presented the second largest inhibition zone, 6.27 (3.08) mm, significantly different from that of the non-iodoform pastes (P < 0.05). It can be concluded that iodoform paste, alone or in combination with ZOE + Ca(OH)2, demonstrates high antimicrobial activity, while the combination of ZOE + Ca(OH)2 demonstrates moderate activity.

RESUMO

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.

RESUMO

OBJECTIVES: To evaluate the peri-implant tissue changes and esthetic outcomes of cemented and screw-retained crowns of single-tooth implants in the esthetic zone using zirconia abutments. MATERIAL AND METHODS: An electronic search was performed on nine databases. The risk-of-bias was assessed by the revised Cochrane risk-of-bias tool for randomized (RoB 2) and non-randomized (ROBINS-I) clinical trials. Marginal bone level change, soft tissue thickness, bleeding on probing, probing depth, survival rates of implants and crowns, complications, plaque and papilla indexes, and pink esthetic score data were extracted and analyzed. The certainty of evidence was accessed through the GRADE approach. RESULTS: Nine records were included and 7 were used in the meta-analyses. Screw-retained crowns presented greater marginal bone level change (MD -0.04 [-0.08, -0.00] p = 0.04, I2  = 0%) compared to cemented crowns up to 1-year. At 3 and 4 years no significant differences (p > 0.05) were observed. Soft tissue thickness did not differ between groups (p > 0.05). The bleeding on probing was higher in cemented group than in screw-retained crowns at 1-year (MD 0.17 [0.08, 0.27] p = 0.0005, I2  = 0%), at medium-term periods (3 and 4 years) no statistically significant differences (p > 0.05) were observed for this outcome. Probing depth, survival rates of implants and crowns, complications, and plaque index, as well as esthetic analysis using the papilla index and pink esthetic score did not differ statistically (p > 0.05) between both retention systems at short and medium-term periods. CONCLUSION: The connection system considering zirconia abutments presented no influence on peri-implant parameters and esthetics evaluation for medium-term periods (3 and 4 years).

RESUMO

OBJECTIVES: To summarize the clinical performance of anodized implants connected to different prostheses design after immediate/early (IL) or conventional loading (CL) protocols. MATERIALS AND METHODS: Seven databases were surveyed for randomized (RCTs) and non-randomized controlled clinical trials (CCTs). Studies comparing IL vs. CL protocol of anodized implants supporting single crown, fixed partial denture (FPD), full-arch fixed dental prosthesis (FDP), or overdenture were included. Risk-of-bias was evaluated using Cochrane Collaboration tools. Meta-analyses for different follow-up were analyzed, followed by heterogeneity source assessment and GRADE approach. The outcomes included implant survival rate, marginal bone loss (MBL), implant stability quotient (ISQ), probing depth (PD), plaque index (PI), and peri-implantitis prevalence. RESULTS: From 24 eligible studies, 22 were included for quantitative evaluation. Most RCTs (58%, n = 11) and all the 5 CCTs had high and serious risk-of-bias, respectively. Overall, pooling all prosthesis design, no difference between IL vs. CL protocols was observed for all outcomes (p > .05). However, according to prosthesis type subgroups, CL reduced MBL for full-arch FDP (p < .05). In a point-in-time assessment, with overdenture, although IL presented higher PI (12 months), it showed lower MBL (≥24 months), higher ISQ (3 months), and lower PD (6 and 12 months) (p < .05). Conversely, PD was higher for IL in single crown (3 and 6 months) (p < .05). Regarding MBL, IL demonstrated higher mean difference for full-arch FDP (36 months) and FPD (12 and 36 months) (p < .05). CONCLUSION: Within the limitations of this study, overall, there is no significant difference in the outcomes between IL and CL loading protocols.

RESUMO

BACKGROUND AND OBJECTIVES: To present a world panorama of the published papers on bruxism in children and adolescents, emphasising the characteristics of studies related to the sleep features of these patients. METHODS: Literature searches were conducted in six databases without language or date restrictions. Data on the titles, types of study, main subjects, countries of origin, keywords, years of publication, authors and their network collaborations, journals and sleep studies were extracted and analysed using VantagePoint™ software. RESULTS: A total of 725 studies met the eligibility criteria. Most included only children (75.31%), with observational design (66.34%), and risk or aetiology (53.93%) as the main subject. Brazil (18.06%) and Brazilian authors (54.84%) had the largest number of studies, with a low amount of network collaboration. The Journal of Oral Rehabilitation published most of the studies (6.2%); publications in this field have grown considerably from 2000 to 2020. Of the studies, 123 (16.96%) included sleep studies; night sweating, restless sleep, sleep talking, mouth breathing, snoring, obstructive sleep apnoea syndrome, sleep-disordered breathing, nightmares, poor sleep quality and duration, and daytime naps were significantly associated with bruxism in most. CONCLUSION: Studies on bruxism in children and adolescents have increased in the past 20 years, with most being observational, and risk or aetiology as the main subject. Brazil and the Journal of Oral Rehabilitation have published most in the field. Sleep studies have shown some features associated with bruxism, such as night sweating, restless sleep, somniloquy, snoring, breathing problems, nightmares, daytime naps, and poor sleep quality and duration.

RESUMO

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.

RESUMO

Background: Neurodegenerative diseases are a group of progressive disorders that affect the central nervous system (CNS) such as Alzheimer, Parkinson, and multiple sclerosis. Inflammation plays a critical role in the onset and progression of these injuries. Periodontitis is considered an inflammatory disease caused by oral biofilms around the tooth-supporting tissues, leading to a systemic and chronic inflammatory condition. Thus, this systematic review aimed to search for evidence in the association between neurodegenerative disorders and periodontitis. Methods: This systematic review was registered at International Prospective Register of Systematic Reviews (PROSPERO) under the code CRD 42016038327. The search strategy was performed in three electronic databases and one gray literature source-PubMed, Scopus, Web of Science, and OpenGrey, based on the PECO acronym: observational studies in humans (P) in which a neurodegenerative disease was present (E) or absent (C) to observe an association with periodontitis (O). The Fowkes and Fulton checklist was used to critically appraise the methodological quality and the risk of bias of individual studies. The quality of evidence was assessed by the Grading of Recommendations Assessment, Development and Evaluation (GRADE). Results: From 534 articles found, 12 were included, of which eight were case-control, three were cross-sectional, and one was a cohort, giving a total of 3,460 participants. All the included studies reported an association between some neurodegenerative diseases and periodontitis and presented a low risk of bias. According to the GRADE approach, the level of evidence of probing pocket depth was considered very low due to the significant heterogeneity across the studies' upgrading imprecision and inconsistency. Conclusions: Although all the included studies in this review reported an association between neurodegenerative diseases and periodontitis, the level of evidence was classified to be very low, which suggests a cautious interpretation of the results.

RESUMO

OBJECTIVE: To develop, validate, and apply an instrument for assessing the children's perception regarding pediatric dentist's appearance, based upon the influence of age, gender, previous dental experience, and anxiety. STUDY DESIGN: Images and a nine-item questionnaire were developed. The acceptability, convergent-construct validity, and reliability based on reproducibility and internal consistency were evaluated. The validated instrument was applied in a cross-sectional study, with children (n=120) aged 7-12 years asked to evaluate images of pediatric dentists wearing different dental attire (A:all-white (control); B:printed coat and cap, colorful face mask; C:printed coat, cap and face mask; and D:white coat and cap, printed face mask). Children's age, gender, and previous dental experiences were collected with the guardians. The Children's Fear Survey Schedule-Dental Subscale assessed children's anxiety. Descriptive and inferential statistics were carried out (p<0.05). RESULTS: The instrument showed excellent acceptability, construct validity with moderate and strong correlations (>0.40), satisfactory reproducibility (ICC >0.70), and internal consistency (Cronbach's alpha coefficient >0.70). Considering only the attire, the children's perceptions were more positive with the use of attire C and D (p<0.05). Intergroup analysis of all the variables did not identify a statistically significant difference (p>0.05). In the intragroup analysis, compared to attire A: younger children have higher perception scores to attire D; girls, children with previous experience and without anxiety favored attire C and D; and children without previous experience showed no difference in comparison to A but did between B and C (p<0.05). CONCLUSION: The C and D attires promoted a more positive perception of the appearance of a pediatric dentist when compared to A; however, age, gender, previous dental experience, and anxiety did not influence the perception scores.

RESUMO

Lead (Pb) is one of the most toxic and abundant elements in the earth's crust, which is pointed out that the intoxication caused by it may damage biological systems. This systematic review with meta-analysis aimed to evaluate the association between Pb exposure and neurological damage. This work was executed according to PRISMA guidelines, and seven online databases were consulted. Based on the PECO strategy, studies presenting humans as participants (populations) exposed to Pb (exposure) compared to non-exposed to Pb (control) evaluating the neurological impairment (outcome) were included. The quality and risk of bias were verified by Fowkes and Fulton checklist. Two meta-analyses were conducted considering Digit Symbol and Profile Mood tests. The certainty of the evidence was evaluated with the GRADE tool. This review identified 2019 studies, of which 12 were eligible according to the inclusion criteria. Eight were considered with a low risk of bias. All the studies elected showed that exposure to Pb is associated with neurological damage, but the meta-analysis did not show any difference for the evaluated tests, and the certainty of the evidence was considered very low. Nevertheless, the included studies showed that Pb occupational exposure is associated with neurological damage, and the main parameters evaluated for possible neurological damage were related to mnemonic aspects, reaction time, intelligence, attention disorders, and mood changes. Thus, our results revealed that a definitive demonstration of an association of Pb and neurological changes in humans is still a pending issue. Future studies should take into consideration more confident methods to answer this question.

RESUMO

Sleep bruxism (SB) is a behavior of central origin that is related to different factors. This systematic review aimed to determine the prevalence of clinical signs and symptoms of the masticatory system and their association in children with SB. A structured search in ten databases were taken. Two authors independently selected studies, extracted the data, study quality assessment and graded the evidence. A meta-analysis of proportion and association was performed under random-effect model, confidence interval of 95% and p < 0.05 for pulled values. Were included 22 studies, and their overall quality was poor. The more common clinical signs and symptoms of the masticatory system in children with SB were primary canine wear (P:84.13, 95% CI:78.13-89.32; p = 0.248; I2 25.05), dental wear (P:73.76, 95% CI:38.73-96.91; p < 0.001; I2 97.62) and headache (P:52.85, 95% CI:38.92-66.56; p < 0.001; I2 93.65). The prevalence of SB in children was 31.16% (P:31.16, 95% CI:22.18-40.92; p < 0.001; I2 98.56). There was no significant risk of dental wear and headache in children with SB. There is low to very low certainty of the evidence. The more prevalent clinical signs and symptoms of the masticatory system presented in children with SB were primary canine wear, dental wear and headache. Further studies of high quality are still needed to elucidate these important questions.
