Validating evidence for the knowledge, management and involvement of dentists in a dental approach to sickle-cell disease

This study validated the content of an instrument designed to assess the knowledge, involvement (attitudes) and management (practice) of dentists relative to sickle-cell disease (KAPD-SCD). The instrument consisted of five domains composed of a total of thirteen items: I. Dentist's self-assessment relative to sickle-cell disease; II. Dentist's knowledge of the repercussions of sickle-cell disease on the stomatognathic system; III. Dentist's knowledge of the complications of sickle-cell disease in the stomatognathic system; IV. Dentist's knowledge concerning the dental management of sickle-cell disease patients; and V. Dentist's involvement in an approach to sickle-cell disease. Twelve experts assigned scores to each item of the instrument. The criteria were clarity, understanding and appropriateness, leaving open fields for comments. Descriptive and content analyses of the data were made. Each expert analyzed 39 assessment units. The percentages considered for agreement were high (>80%), medium (70%-80%), or low (<70%), and each item was maintained or revised according to the percentage observed. There was high consensus in 74% of the assessment units (the corresponding items were maintained), medium consensus in 24% of them (the corresponding items were revised), and disagreement in 2% of them, namely as regards the "appropriateness" of item 5 ("Are there oral complications in sickle-cell disease?"), which was revised. The final version of the instrument had 16 items for different applications such as in the clinical care program, teaching program, or research program, with different cut-off scores for each application. In conclusion, the level of agreement among experts showed evidence of the content validity of the instrument.

EZH2 immunoexpression in pleomorphic adenoma and adenoid cystic carcinoma and clinicopathological features

The aim of this study was to evaluate the expression of the EZH2 protein and describe the clinical and microscopic characteristics of adenoid cystic carcinoma (ACC) and pleomorphic adenoma (PA). The study included 16 ACC cases and 12 PA. All ACC and PA cases were positive for EZH2 and the ACC samples showed significantly higher EZH2 expression. The clinical and microscopic covariates were described in relation to EZH2 staining in ACC samples. The highest mean values of EZH2 were observed in cases with local metastasis, recurrence, perineural invasion, and predominantly cribriform growth pattern without solid areas. EZH2 is a potential marker of malignancy.

Oral conditions of children with microcephaly associated with congenital Zika syndrome: a cross-sectional study

The aim of the present study was to compare the oral conditions of children with congenital Zika syndrome (CZS)-associated microcephaly, non-CZS-associated microcephaly, and normotypical children, as well as to characterize their sociodemographic aspects and medical history. A paired cross-sectional study was carried out on 14 children with CZS-associated microcephaly and 24 age-matched controls, in Belo Horizonte, in southeastern Brazil. Children's oral conditions were assessed: dental caries experience (dmft/DMFT indices); developmental defects of enamel (DDE) index; dental anomalies; mucosal changes; lip sealing, and malocclusion (overjet, overbite, and/or posterior crossbite alterations). The quality of oral hygiene was analyzed by the simplified oral hygiene index. The children's mothers also answered a questionnaire about sociodemographic and medical history data. The variables were analyzed descriptively. Female participants were more prevalent (60.5%), and the mean age of the participants was 4.9 years (±1.4) (range: 2-8 years) and 92.1% of their exhibited some oral condition. All participants with CZS-associated microcephaly showed absence of lip sealing and had malocclusion (100.0%). When compared to the other groups, children with CZS had a higher percentage of dental anomalies (35.7%), mucosal changes (71.4%), and unsatisfactory oral hygiene (64.3%). In a sample composed mainly of female participants aged less than 5 years, the prevalence of oral conditions and unsatisfactory oral hygiene was higher in the group with CZS-associated microcephaly, followed by the group with non-CZS-associated microcephaly. Normotypical children had the highest percentage of dental caries experience.

Association between management, human resources, and care provided to patients with special healthcare needs in dental specialty centers in Brazil: A cross-sectional study

AIMS

This study aimed to identify the association between management and human resource factors with the performance of dental care provided to patients with special health care needs (SHCN) in secondary care in Brazil in the second cycle of the Program for Quality Improvement and Access to Dental Specialty Centers (PMAQ-CEO).

METHODS AND RESULTS

This study is a secondary data analysis from the second cycle from PMAQ-CEO, which evaluated 1097 Dental Specialty Centers (DSCs), conducted in 2018. Seventeen independent variables taken from dentists' training, and dental team management characteristics were analyzed to assess their influence on the reported "Performance of care for SHCN patients". An estimated score was generated from their performance on 23 questions related to the physical and human structure and work processes in the oral health care of SHCN patients in the DSCs. Negative binomial regression model with values p ≤ 0.05 were considered significant. Data analysis included residual deviation to the degree of freedom and the chi-square test. The patient care performance score with SHCN increases significantly when the DSC has a manager (RR = 1.019; CI = 1.011-1.026) and goal monitoring and analysis (RR = 1.012; CI = 1.007-1.005). By contrast, the DSCs in which the dentist is a statutory public servant (RR = 0.998; CI = 0.997-1.000) and performs additional unhealthy or hazardous duties (RR = 0.998; CI = 0.996-0.999) are less likely to provide a higher quality care.

CONCLUSION

The heterogeneity and low-performance scores for dental care provided to SHCN was identified in Brazilian health services. It was possible to verify that management and human resource factors of the DSCs were associated with the performance of dental care provided to SHCN patients.

E-learning as a strategy in dentistry in the context of COVID-19: a path to follow?

The current study aims to assess the effectiveness of e-learning in compliance with the new biosafety recommendations in dentistry in the context of COVID-19 applied to the clinical staff of a dental school in Brazil. A quasi-experimental epidemiological study was carried out by means of a structured, pre-tested online questionnaire, applied before and after an educational intervention, using an e-learning format. After data collection, statistical tests were performed. A total of 549 members of the clinical staff participated in the study in the two collection phases, with a return rate of 26.9%. After the e-learning stage, a reduction was found in the reported use of disposable gloves, protective goggles, and surgical masks. The course had no impact on the staff's knowledge concerning the proper sequence for donning PPE and showed 100% effectiveness regarding proper PPE doffing sequence. Knowledge about avoiding procedures that generate aerosols in the clinical setting was improved. Despite the low rate of return, it can be concluded that online intervention alone was ineffective in significantly improving learning about the new clinical biosafety guidelines. Therefore, the use of hybrid teaching and repetitive training is highly recommended.

Building an antimicrobial stewardship program: A narrative of six years under the Donabedian perspective

Introduction: Antimicrobial resistance (AMR) is increasing and represents one of the world's major challenges. AMR increase morbimortality, length of hospital stay and costs. Antimicrobial Stewardship Programs (ASP) are one of the key strategies to promote the rational use of antimicrobials since AMR is mostly driven by antimicrobial consumption. Objective: To describe the ASP implementation in a teaching hospital from the perspective of Donabedian quality assessment and the Brazilian regulatory requirements. Method: This was a descriptive study with secondary data collection, including document review of the ASP. The study setting was a general public 392-bed hospital. The ASP activities were performed by the hospital infection control committee (HICC), hospital pharmacy (HP) and diagnostic support laboratory (DSL). The description of the three services mainly involved in the ASP was based on a quality assessment model involving the dimensions of "structure", "process" and "result" proposed by Donabedian. The distribution among dimensions was guided by the checklist of essential elements of the ASP that compose the Brazilian regulatory requirements. The checklist was applied in July, 2022, and the ASP results described from 2016 to 2021. Results: ASP actions have been gradually implemented since 2008 with the implementation of HICC and improved over the years. Regarding structure, the investments in technology were mapped, quantifying 26 computers and three software programs employed to computerize the ASP processes performed in specific physical areas by HICC, HP and DSL. Institutional guidelines used by HICC, HP and DSL guided clinical practices to operationalize ASP. The evaluation metrics improved for 10 indicators and worsened for four indicators. From the 60 items composing the checklist, the hospital met the requirements in 73.3% of the items (n = 44). Conclusion: This study described the implementation of ASP in a teaching hospital, applying the Donabedian perspective. Although the hospital still does not have a classic ASP model, there were investments to improve structure, processes and results, aiming to comply with international guidelines. A high proportion of key elements of ASP in the hospital were followed according to the Brazilian regulatory requirements. Aspects related to antimicrobial consumption and the emergence of microbial resistance deserve further investigations.

Professional Factors Associated with Case Resolution without Referrals of Orofacial Pain Cases to Secondary Dental Care by Telehealth in Brazil: A Cross-Sectional Study in 2019 and 2020

This study aimed to identify professional factors associated with case resolution without a referral of orofacial pain to secondary health care by Brazilian Primary Health Care (PHC) practitioners who demanded asynchronous teleconsulting, stratified by year, in 2019 and 2020 (the COVID-19 Pandemic burst). A cross-sectional study employed secondary databases from asynchronous teleconsulting Telehealth Brazil Networks from January 2019 to December 2020. The outcome was the dichotomous variable "If referral to secondary care was avoided." As covariates: sex, healthcare professions, and category of orofacial pain doubts. A negative binomial regression model estimated each covariate's unadjusted and adjusted PR (95%CI) and p values, stratified for 2019 and 2020. There was a difference in descriptive factors associated with case resolution without a referral from 2019 to 2020. Females prevailed in both years, and the total demand decreased to a third from 2019 to 2020. The rate of resoluteness decreased by 19.1%. In 2019, nurses (PR = 0.69 CI 95% 0.57-0.83) and other professionals (PR = 0.84 CI 95% 0.73-0.97) showed less frequency of case resolution without a referral than did general dentists. In 2020, oral-cavity-related doubts (PR = 1.18 CI 95% 1.06-1.32) and temporomandibular disorders (PR = 1.33 95% 1.15-1.54) surpassed other causes of orofacial pain in case resolution without a referral, and female professionals avoided referrals more frequently than men (PR = 1.24 CI 95% 1.21-1.38). In conclusion, in 2019, oral cavity doubts and the PHC profession influenced the case resolution. Female professionals and oral cavity doubts scored the higher case resolution without a referral for the service in 2020.

Association of sociodemographic factors with the prescription pattern of opioids for dental patients: a systematic review

Aim To evaluate the association of patients' sociodemographic factors (sex, age, ethnicity, income, educational level, living environment and health insurance) with the prescription pattern of opioids provided by oral health practitioners.Methods Observational studies that evaluated the association of patients' sociodemographic factors and the likelihood of receiving an opioid prescription provided by an oral health practitioner were eligible. Electronic searches were conducted in Medline (PubMed), Embase, Scopus, Web of Science, LILACS, SciELO, Google Scholar, and OpenGrey up to March 2021. Two authors independently screened the studies, performed data extraction, and assessed the risk-of-bias using the critical appraisal tools developed by the Joanna Briggs Institute (JBI). Certainty of the evidence was assessed with the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE).Results Eight studies were included in this systematic review. Publication year ranged from 2011 to 2021. Narrative synthesis showed with very low certainty of evidence that younger individuals were more likely to receive a prescription of opioids than older individuals. Regarding the other sociodemographic factors and the prescriptions of opioids in dentistry, the evidence is controversial. Risk of bias was low for most items assessed in the included studies.Conclusion The available evidence suggests that there is an association between patients' sociodemographic factors and the prescription patterns of opioids provided by oral health practitioners.

Mother's education and family relations protect children from dental caries experience: a salutogenic approach

The objective of this study was to identify dental caries-protective factors among 5-year-old children using the salutogenic theory. A cross-sectional study was conducted in a small-sized municipality in the Southeast region of Brazil, with a representative sample of 247 children registered in preschool and their respective mothers. The data were collected through questionnaires administered to the mothers about the socioeconomic, behavioral, and biological aspects of the mother and children. Additionally, the collections included validated instruments concerning psychosocial aspects, such as a sense of coherence, resilience, family cohesion and religiosity, and intraoral examinations of the children through the decayed-missing-filled primary teeth (dmft) index. All examinations were performed by a trained and calibrated examiner. The non-adjusted and adjusted odds ratios (OR) and their respective confidence intervals (CI) were estimated using multiple logistic regression with a hierarchical model. Among the examined children, 41.7% were caries-free. In the final model, the chances of the absence of dental caries experience (dmft = 0) were greater in children with mothers who had higher education levels (> 8 years of study) (OR = 2.55 [95%CIi:1.42-4.59]) and those who lived in an environment of high family cohesion (OR = 3.66 [95%CI: 1.19-11.29]). The results indicated that mothers' level of education and family relationships are protective factors against dental caries in 5-year-old children, which overlapped with behavioral and biological factors.

Epidemiological Factors of Periodontal Disease Among South Indian Adults

Introduction

Oral conditions exist worldwide, and are related with astounding morbidity. Indian adults’ incidence of mild and moderate periodontal conditions was nearly 25%, while about 19% of adults experience severe periodontitis.

Objective

The aim of this study was to analyse epidemiological factors of periodontal disease among a south Indian population based on the role of sociodemographic factors, habitual factors and set of oral health knowledge, attitude, and behaviour measures.

Methods

A sample of 288 participants above 18 years of age residing in Tamil Nadu, India took part in this cross-sectional study. Based on WHO criteria, periodontal disease was measured in our study. Age, ethnicity, smoking, education, and oral health behavior were found to be the covariates. Ordinal logistic regression analysis using R version 3.6.1 was utilized to study the various factors that influence periodontal disease among south Indian adults.

Results

Various demographic factors such as age between 25 and 34 years (AOR = 2.25; 95% CI 1.14–4.55), 35–44 years (AOR = 1.80; 95% CI 0.89–3.64), ≥ 45 years old (AOR = 2.89; 95% CI 1.41–6.01), ethnicity (AOR = 2.71; 95% CI 1.25–5.81), smoking (AOR = 0.38; 95% CI 0.16–0.65), primary level education (AOR = 0.07; 95% CI 0.01–0.50) high school level education (AOR = 0.06; 95% CI 0.01–0.27), university level education (AOR = 0.08; 95% CI 0.01–0.36) and an individual’s oral health behavior (AOR = 0.59; 95% CI 0.32–1.08) were found to be related with periodontal disease among the south Indian population. The maximum log likelihood residual deviance value was 645.94 in the final model.

Conclusion

Based on our epidemiological findings, sociodemographic, habitual factors and oral health behavior play a vital role in an individual’s periodontal status among south Indian adults. An epidemiological model derived from the factors from our study will help to bring better understanding of the disease and to implement various preventive strategies to eliminate the causative factors.

Biosafety in Dental Health Care During the COVID-19 Pandemic: A Longitudinal Study

Background

The coronavirus disease 2019 (COVID-19) pandemic had quite an impact on dental health care. Concerns about the risk of SARS-CoV-2 transmission through contaminant fluids and droplet formation during several dental procedures highly impacted dental health care, drastically reducing the number of dental practices worldwide. To monitor SARS-CoV-2 contamination in dental clinics, a longitudinal study was carried out during the return of dental practice at university.

Methods

Dental health care professionals [(DHCPs); teachers, undergraduate dental students, and dental assistants] and patients were screened for SARS-CoV-2 RNA in a dental school clinic environment from 11th January to 12th March 2021 (9 weeks). Serological testing was performed on DHCPs in two-time points. Additionally, samples with low Ct values were sequenced to identify the circulating SARS-CoV-2 variant and possible transmission clusters.

Results

We found a low number of dental staff (5.8%), patients (0.9%), and environment sites (0.8%) positive for SARS-CoV-2. Most positive cases had asymptomatic to mild symptoms, and two asymptomatic DHCPs presented prolonged infection. In the first week after previous exposure to COVID-19, 16.2% of DHCPs had IgM or IgG antibodies against SARS-CoV-2, and 1/3 of them had undetected antibodies in the last weeks. The variant zeta (P.2) could be detected. No cross-infection was observed between participants.

Conclusion

Our study suggests that dental practice can be safely executed when adequate control measures and biosafety protocols are applied. DHCP and patient testing, patient telemonitoring, proper use of personal protection equipment, and sanitization of surfaces are essential to avoid SARS-CoV-2 cross-infection in dental practice.

Efficacy of gastric aspiration to reduce postoperative vomiting after orthognathic surgery: double-blind randomised clinical trial

Orthognathic surgery is a treatment modality indicated to correct dentofacial deformities. Postoperative vomiting can be associated with multifactorial origin mainly correlated to patient-related symptoms, anaesthetic and surgical factors. Swallowed blood has been related to one of those multifactorial vomiting causes. This present study was to compare the efficacy of gastric aspiration after bimaxillary orthognathic surgery. A double blind randomised clinical trial was carried out and patients were divided in two groups (n = 44/39 respectively). There was statistically significant difference between the control and study groups in the overall incidence of vomiting (p = 0.031) A stratified analysis by sex between both groups was performed demonstrating a four-fold eduction in the odds for vomiting events independent of patient gender (OR = 0.24; 95% CI 0.07 to 0.72). Gastric aspiration after orthognathic surgery can reduce the effects of postoperative vomiting decreasing inpatient period and, consequently, hospitalisation costs.

Perspectives on Social and Environmental Determinants of Oral Health

Most oral conditions have a multifactorial etiology; that is, they are modulated by biological, social, economic, cultural, and environmental factors. A consistent body of evidence has demonstrated the great burden of dental caries and periodontal disease in individuals from low socioeconomic strata. Oral health habits and access to care are influenced by the social determinants of health. Hence, the delivery of health promotion strategies at the population level has shown a great impact on reducing the prevalence of oral diseases. More recently, a growing discussion about the relationship between the environment, climate change, and oral health has been set in place. Certainly, outlining plans to address oral health inequities is not an easy task. It will demand political will, comprehensive funding of health services, and initiatives to reduce inequalities. This paper sought to give a perspective about the role of social and physical environmental factors on oral health conditions while discussing how the manuscripts published in this Special Issue could increase our knowledge of the topic.

Role of management and human resource factors on matrix support in secondary oral health care in Brazil

OBJECTIVES

To investigate the association between health management and human resource factors on matrix support (MS) in a nationally representative sample of Dental Specialty Centres (DSCs) in Brazil.

METHODS

This survey included 1042 DSCs (Response rate = 94.99%) in the second cycle of the National Program for the Improvement of the Quality and Access to the Dental Specialty Centres (PMAQ-CEO, in Portuguese) in 2018. Previously trained interviewers extracted information on MS, health management and human resources of the DSC by using a structured instrument. An MS score was created by adding the number of positive answers to the 10 MS questions. Negative binomial regression models were used to estimate the unadjusted and adjusted rate ratios (RR) and corresponding 95% confidence interval (CI).

RESULTS

Of all the DSCs (n = 1042), 116 (11.1%) performed all 10 MS procedures. Those DSCs with a manager who had a higher education degree in the area of Public Health or Public Management (RR = 1.01, 95% CI, 1.01-1.02) and with human resources that received incentives, bonuses or financial awards for performance related to the PMAQ-CEO result (RR = 1.01 95% CI 1.01-1.02) are more likely to perform MS, when compared to the reference categories. The DSCs that are more likely to perform MS include those that developed actions as a result of periodic planning and evaluation with confirmatory documentation (RR = 1.06, 95% CI; 1.01-1.10); those that received support for planning and organizing the work scheme (RR = 1.03, 95% CI; 1.01-1.05); those that monitored and analysed the goals set for each specialty offered at the DSC, with (RR = 1.06, 95% CI; 1.01-1.10) or without confirmatory documentation (RR = 1.06, 95%CI; 1.02-1.11); those whose team periodically performed self-assessment processes, using the Ministry of Health's formal self-assessment (AMAQ in Portuguese) (RR = 1.04, 95% CI; 1.02-1.05); those who followed clinical guidelines (with confirmatory documentation) regarding the referral of patients from primary care to the DSC (RR = 1.02, 95% CI; 1.01-1.04). On the contrary, DSCs that did not use the results achieved in previous PMAQ cycles in the organization of the DSC's team work scheme proved to be less likely to perform MS (RR = 0.98, 95% CI; 0.96-0.99).

CONCLUSIONS

Matrix support is associated with human resources and management factors in secondary oral health care in Brazil. Continuing professional development and some management characteristics are important for secondary dental care quality and could be considered in health policy initiatives.

Contextual and individual factors associated with dental pain in adolescents from Southeastern Brazil

The aim of this study was to assess the factors associated with dental pain in adolescents from the state of Minas Gerais, Brazil. Individual data on adolescents aged 15 to 19 years were collected from the SB Minas survey secondary database. Dental pain over the past 6 months, assessed by a questionnaire, was used as the dependent variable. Sex, income, skin color, prevalence of untreated dental caries, periodontal health, dental treatment needs, and time of last dental appointment were analyzed as individual covariates. Allocation factor, Human Development Index (HDI), Gini coefficient, illiteracy rate, unemployment, 50% and 25% of the Brazilian monthly minimum wage, primary healthcare coverage, oral health team coverage, access to individual healthcare, and supervised toothbrushing average rate were the analyzed contextual variables. A multilevel analysis was conducted for the individual and contextual variables. Statistical analyses used hierarchical linear and nonlinear modeling to infer an association between the different levels. Male adolescents had a lower prevalence of dental pain (OR = 0.53; 95%CI = 0.37-0.75). There was an association between dental pain and low income (OR = 1.58; 95%CI = 1.07-2.33), prevalence of untreated dental caries (OR = 1.25; 95%CI = 1.11-1.40), periodontal health (OR = 1.80; 95%CI = 1.04-3.09), and dental treatment needs (OR = 6.93; 95%CI = 3.96-12.14). Sociodemographic and clinical factors at the individual level were associated with the outcome but not with contextual variables. These findings reinforce the need to address these factors for effective community health actions.

Factors associated with oral pain and oral health-related productivity loss in the USA, National Health and Nutrition Examination Surveys (NHANES), 2015-2018

Background

Our aim was to identify clinical and sociodemographic factors associated with oral pain and oral health-related productivity loss among US adults.

Methods

We included adults aged ≥30 years who completed the dental examination, had at least one natural tooth, and provided an answer about their oral pain experience or oral health-related productivity loss in the 2015–2018 National Health and Nutrition and Examination Survey (NHANES). We performed descriptive analyses and multivariable binary logistic regression analyses on weighted data.

Results

One out of four adults had oral pain and 4% reported oral health-related productivity loss occasionally or often within the last year of the survey. The odds of oral pain were higher among non-Hispanic black (OR = 1.35; 95%CI = 1.08–1.62) and non-Hispanic Asian individuals (OR = 1.38; 95%CI = 1.07–1.78) compared to non-Hispanic white individuals, and individuals with untreated dental caries (OR = 2.06; 95%CI = 1.72–2.47). The odds for oral health-related productivity loss were 13.85 times higher among individuals who reported oral pain (95%CI = 8.07–23.77), and 2.18 times higher among individuals with untreated dental caries (95%CI = 1.65–2.89). The odds of oral pain and reported oral health-related productivity loss decreased as family income increased.

Conclusions

Factors including non-Hispanic black race/ethnicity, lower socio-economic status, and untreated dental caries are associated with oral pain experience, which increases the odds of oral health-related productivity losses. Identifying factors associated with oral pain and productivity loss will enable clinicians, policymakers, and employers to proactively target and prioritize the higher-risk groups in early interventions and policies.

Association of sociodemographic factors with the prescription pattern of opioids for dental patients: A systematic review protocol

INTRODUCTION

Oral health practitioners are responsible for a significant share of opioid prescriptions that seem to be influenced by many aspects, including sociodemographic factors. However, there is no consensus on the factors associated with opioid prescription in Dentistry.

OBJECTIVE

To identify whether patients' sociodemographic factors are associated with the prescription pattern of opioids in Dentistry.

MATERIALS AND METHODS

This systematic review will include observational studies (cross-sectional, case-control, and cohort). Electronic searches will be conducted in MEDLINE (PubMed), EMBASE, Scopus, Web of science, LILACS, SciELO, and Google Scholar. Grey literature will also be consulted. Two independent reviewers will screen all retrieved articles for eligibility, extract data, and assess the methodological quality of the included studies. The results will be presented as a narrative synthesis and, where possible, a meta-analysis will be conducted. Certainty of the evidence will be assessed with the Grading of Recommendations, Assessment, Development, and Evaluation approach.

Access to oral health care services for individuals with rare genetic diseases affecting skeletal development

OBJECTIVE

To identify factors associated with oral health care services for individuals with and without rare genetic diseases.

MATERIALS AND METHOD

A cross-sectional study was undertaken, with 140 individuals paired by sex and age (70 with rare genetic diseases and 70 without), aged between 3 and 27 years, and their parents. The sample was selected from two reference hospitals for patients with rare genetic diseases in southeastern Brazil. The parents completed a questionnaire on individual aspects and their child's medical/dental history. Participants who did and did not suffer from rare genetic diseases were examined for dental caries, malocclusion, dental anomalies, and oral hygiene. The theoretical model Directed Acyclic Graphs (DAG) was used to identify possible confounding variables in the association between rare diseases and access to dental care. Descriptive analyses and non-matched and matched logistic regression models (p < 0.05) were carried out.

RESULTS

The chance of individuals without rare genetic disease having access to oral health care service was 5.32 times higher (95% CI 2.35-12.01) than those with such conditions. Individuals who had not suffered upper respiratory tract infections had a 3.16 times greater chance of being in the group with access to oral health care service (95% CI 1.45-6.90).

CONCLUSION

Individuals with no rare genetic diseases and no history of upper respiratory tract infections had a greater chance of belonging to the group of individuals with access to a dental service. Individuals with rare genetic diseases have less access to oral health care.

Demographic and Habitual Factors of Periodontal Disease among South Indian Adults

The aim of this study was to evaluate the performance of a set of sociodemographic and habits measures on estimating periodontal disease among south Indian adults. This cross-sectional study was carried out among 288 individuals above 18 years old in Tamil Nadu, India. The outcome of the study was periodontal disease, measured by WHO criteria. The covariates were age, ethnicity, smoking and alcohol habit. The assessment of factors predicting periodontal disease was carried out by multiple logistic regression analysis using R version 3.6.1. The demographic factors like age group (AOR = 3.56; 95% CI 1.69-7.85), ethnicity (AOR = 6.07; 95% CI 2.27-18.37), non-alcoholic (AOR = 0.31; 95% CI 0.13-0.64) and non-smoking (AOR = 0.33; 95% CI 0.15-0.67) were found to be associated with the outcome. The maximum log likelihood estimate value was -30.5 and AIC was 385 for the final model, respectively. Receiver operating characteristic (ROC) curve for the periodontal disease was 0.737. We can conclude that sociodemographic factors and habits were useful for predicting periodontal diseases.

Effectiveness of local hemostatic to prevent bleeding in dental patients on anticoagulation: A systematic review and network meta-analysis

This study aimed to determine the effectiveness of hemostatic protocols to prevent bleeding in dental procedures among individuals undergoing oral anticoagulation therapy. A systematic review and network meta-analysis were accomplished. Searches of literature and grey literature were performed in different electronic databases. Clinical trials were considered as part of the inclusion criteria. Data extraction and assessment of the risk of bias of the included articles were performed. Assessment of the certainty of evidence was also performed. As results we find that the N-butyl-2-cyanoacrylate [RR -35.00 (95% CI - 107.12, -5.78)], calcium sulfate (CaSO₄) [RR -5.62 (95% CI -11.41, -1.03)], and tranexamic acid (TXA) [RR -3.46 (95% CI -7.63, -0.77)] showed beneficial effects compared to placebo. However, only TXA presented beneficial effects with moderate certainty evidence. N-butyl-2-cyanoacrylate and CaSO₄ presented very low certainty evidence. In the comparisons between the hemostatic agents, no differences were observed. For the mean bleeding time, no significant difference in the comparisons was observed as well. Concluding, bleeding events in individuals on oral anticoagulation decreased with the use of TXA compared to placebo. N-butyl-2-cyanoacrylate and CaSO₄ were also superior to placebo, but the certainty of evidence was low. For the mean bleeding time, no significant difference in hemostatic agents was observed.

Oral Health-Related Quality of Life in Anticoagulated Patients with Warfarin Treatment: A Cross-Sectional Study

To evaluate factors associated with oral health-related quality of life (OHRQoL) in patients under oral anticoagulant therapy with warfarin, a cross-sectional study was conducted. Validated questionnaires assessed self-reported periodontal disease, demographic variables, and OHRQoL using the short version of the Oral Health Impact Profile (OHIP-14) instrument. After calibration (Kappa > 0.60), an examiner evaluated patients' experience with dental caries and the need for dental prostheses. Statistical analysis involved proportions and measures of central tendency. Negative binomial regression models were used to estimate the rate ratios (RR) and the corresponding 95% confidence interval (CI). The sample consisted of 158 individuals, with a mean age of 58.8 years (SD = 12.1), of which 62.7% of the participants were women. The OHIP-14 mean was 10.62 (SD = 10.92). A higher OHIP-14 total score (worse OHRQoL) was associated with ethnic group, age, periodontal disease self-report, dental caries, and oral health self-report. Demographic and clinical factors can negatively influence the perception of anticoagulated patients on OHRQoL.

Effectiveness of hemostatic protocols for the prevention of bleeding during oral procedures among individuals receiving anticoagulation therapy: a systematic review protocol

OBJECTIVE

The objective of this review is to determine the effectiveness of hemostatic protocols for the prevention of bleeding during dental procedures among individuals receiving oral anticoagulation therapy.

INTRODUCTION

Dental procedures may increase the chance of bleeding in individuals receiving oral anticoagulation therapy. The literature suggests different hemostatic protocols for the prevention of bleeding in these individuals but offers no consensus regarding their effectiveness.

INCLUSION CRITERIA

Randomized controlled clinical trials comparing the effectiveness of different hemostatic protocols for the prevention of bleeding during oral procedures among individuals 18 years or older receiving oral anticoagulation therapy will be included.

METHODS

Computerized searches will be conducted in seven electronic databases. Gray literature and searches in the reference lists of the included articles will also be screened. Two independent reviewers will assess titles/abstracts for potential inclusion against the eligibility criteria. References that meet the eligibility criteria will be included without restriction on the language or date of publication. Assessment of the methodological quality of the included articles and data extraction will be performed. Statistical heterogeneity of meta-analysis will be assessed. In the event of high statistical heterogeneity, sensitivity analysis will be performed. Subgroup analysis will be planned. The certainty of the evidence will be evaluated with the Grading of Recommendations, Assessment, Development and Evaluation.

Câncer Bucal: Análise Socioespacial de uma Amostra Brasileira

Introdução: Medidas socioespaciais são amplamente utilizadas na pesquisa em saúde, mas ainda pouco exploradas em relação ao câncer de boca. Objetivo: Descrever as características sociodemográficas e clínicas do câncer de boca e analisar a distribuição espacial da doença em relação ao status socioeconômico do bairro, incluindo a disponibilidade de centros de saúde. Método: Foram coletados dados sociodemográficos, clínicos e histopatológicos dos pacientes atendidos no período de 2005 a 2015. Foram realizadas análises descritivas dos dados de todas as variáveis. A análise espacial foi realizada por meio do programa R. A distribuição geográfica dos endereços residenciais dos pacientes foi analisada usando a função K de Ripley e mapas de Kernel. A vulnerabilidade socioespacial foi definida pela renda familiar e adequação do domicílio. Resultados: Dos 127 pacientes incluídos, a maioria era do sexo masculino (76,4%), branca ou parda (82,7%), casada (35,4%), com baixa escolaridade (71,6%) e idade média de 59,5 anos. Os casos foram distribuídos em grupos caracterizados por menor renda mediana e condições sanitárias inadequadas. Conclusão: Os casos de câncer oral estão concentrados em regiões de baixa condição econômica. Embora os centros de atenção primária à saúde tenham sido homogeneamente distribuídos por toda a cidade, isso não é suficiente para promover o acesso dos pacientes e o câncer de boca continua sendo diagnosticado tardiamente.

Factors associated with the needs of specialised dental treatment among adults aged 35-44 years old in the state of Minas Gerais, Brazil: a multilevel cross-sectional study

This study evaluated the individual and contextual factors associated with the specialised dental treatment needs of a population of adults aged 35 to 44 years old in the state of Minas Gerais. The individual variables were obtained from the database of the SB Minas Gerais project - a survey of oral health status of the population of Minas Gerais, Brazil. The variables at the municipal level were derived from any available public databases related to oral health services. A multilevel analysis was performed to evaluate the association of independent individuals and contextual variables with or without dental treatment needs in the secondary care of the oral health network. Individuals with a higher income (OR 0.53; CI95% 0.31-0.93) and with greater access to oral health care (OR 0.94; CI95% 0.90-0.99) had less secondary care treatment needs. Income and access to oral health care are related to the needs of specialised dental treatment in Minas Gerais.

Gingival Crevicular Fluid Levels of Human Beta-defensin 2 and 3 in Healthy and Diseased Sites of Individuals with and without Periodontitis

OBJECTIVE

Human beta-defensins (hBDs) play an important role in the susceptibility to periodontitis. This study aimed to evaluate the levels of hBD-2 and hBD-3 in gingival crevicular fluid (GCF) of individuals with and without periodontitis.

METHODS

Twenty periodontally healthy individuals (H) and 20 with periodontitis (P) were recruited. GCF samples were collected from healthy sites (Hh; n=20) from H individuals; and from healthy sites (Ph; n=20), sites with gingival inflammation but no attachment loss (Pg; n=20) and sites with inflammation and attachment loss (Pp; n=20) from P individuals. Levels of hBDs (pg/mL) were determined using ELISA. Comparisons between individuals and among sites were performed through hierarchical linear modelling.

RESULTS

GCF levels [median(Q3-Q1)] of hBD-2 were: Hh=4.80 (0.00-30.69); Ph=33.29 (28.04-38.25); Pg=27.56 (23.14-35.50); and Pp=26.20 (23.20-42.54); and of hBD-3 were: Hh=0.00 (0.00-0.00); Ph=978.44 (760.48-1268.12); Pg=938.19 (806.75- 1266.38); and Pp=613.63 (325.50-854.68). Periodontitis at the individual level was associated with higher levels of hBD-2 (p=0.023) and hBD-3 (p greater than 0.001). No influence of site phenotype was observed on hBDs levels.

CONCLUSION

Individuals with periodontitis presented higher levels of hBD-2 and hBD-3 in the GCF. These levels seemed to be influenced by periodontitis at the individual level but not by periodontal site.

Assessment of patient knowledge on warfarin: An item response theory approach

WHAT IS KNOWN AND OBJECTIVE

There are no instruments to assess the patient's knowledge of oral anticoagulation with warfarin, in which the performance of the items has been evaluated through the item response theory. To evaluate psychometric properties of the Brazilian version of the Oral Anticoagulation Knowledge Test, using the item response theory.

METHODS

This methodological study was developed in an anticoagulation clinic of a university hospital with a sample of 201 patients treated with warfarin. The item response theory was used to evaluate questions regarding psychometric properties and the performance of the Brazilian version of the Oral Anticoagulation Knowledge Test items. The unidimensionality hypothesis was analysed by decomposing the polychoric correlation and the Cronbach's alpha coefficient. An item characteristic curve of the 20 items of the instrument was made to identify the discrimination power of each item of the performance scale.

RESULTS AND DISCUSSION

Correlations were positive and statistically significant among the 20 items, with a Cronbach's alpha coefficient of 0.82. The difficulty parameter ranged from -4.14 to 0.42. The discrimination parameter ranged from 0.41 to 1.89. The items regarding drug-drug/drug-food interactions were able to differentiate knowledge about oral anticoagulation with greater accuracy.

WHAT IS NEW AND CONCLUSION

This study is the first that uses this methodology to evaluate the knowledge on oral anticoagulation therapy with warfarin. The evaluation using item response theory showed that the Brazilian version of the Oral Anticoagulation Knowledge Test is suitable for assessing the patient's knowledge of oral anticoagulation with warfarin. Thus, our findings confirmed the utility of this instrument and provided an essential point of reference for the structuring of health education activities that ensure the individualization of educational interventions in patients on warfarin.

Factors associated with the performance of primary dental health care in Brazil: A multilevel approach

This study evaluated the factors associated with the performance of Brazilian Oral Health Teams (OHTs).This is multilevel research that used data from 12,386 Brazilian OHTs in 2012. The OHTs performance was estimated in previous research by using Item Response Theory model, which employed 20 questions about dental procedures in Primary Care. The first level covariates were based on OHTs procedures such as: the record of pregnant woman dental appointment, provision of dentistry home care, dental appointments scheduled choices, and OHTs in charge for more than 5000 individuals. Moreover, the use of guidelines was accessed concerning delivering prostheses in primary care, referring to secondary care, referring to suspected oral cancer, and providing care towards patients with special needs. Variables included in level 2 were GINI and Human Development Index. Multilevel linear regression models were constructed, estimating linear regression coefficients, 95% confidence intervals, and P values.OHTs performance was different among the 3,613 municipalities analyzed (P < .001), with 36.7% of the variation in the performance of the OHTs being attributed to the variability between municipalities. The adjusted model showed that higher performance OHTs reported attention to pregnant women, dentistry home care and use of dental care guidelines (P < .001). There were lower performance scores for those OHTs with more restricted scheduling (P < .05), compared to those that reported scheduling appointments at any day and time. The best OHTs and population ratio led to a better performance score (P = .010). At the municipal level, better socioeconomic status was associated with better performance of the OHTs (P < .001).OHTs with higher performance are associated with oral health services organizations and municipalities' socioeconomic status.

Socioeconomic status and family functioning influence oral health literacy among adolescents

OBJECTIVE

Evaluate socio-demographic, family and behavioral factors associated with oral health literacy (OHL) in adolescents.

METHODS

Cross-sectional study conducted with adolescents aged 15 to 19 years in Campina Grande, Brazil. Parents/guardians answered a questionnaire addressing socio-demographic data. The adolescents answered validated instruments on family cohesion and adaptability (family adaptability and cohesion evaluation scale), drug use (alcohol, smoking and substance involvement screening test), type of dental service used for last appointment and OHL (Brazilian version of the Rapid Estimate of Oral Health Literacy in Dentistry). Two dentists were trained to evaluate OHL (K = 0.87-0.88). Descriptive analysis was performed, followed by Poisson regression analysis (α = 5%). A directed acyclic graph was used to select independent variables in the study.

RESULTS

The following variables remained associated with better OHL: high mother's schooling level (RR = 1.07; 95%CI: 1.03-1.12), high income (RR = 1.04; 95%CI: 1.01-1.09), white ethnicity/skin color (RR = 1.05; 95%CI: 1.01-1.10), married parents (RR = 1.04; 95%CI: 1.01-1.09), "enmeshed" family cohesion (RR = 1.21; 95%CI: 1.12-1.30), "structured" (RR = 1.06; 95%CI: 1.01-1.12) or "rigid" (RR = 1.11; 95%CI: 1.04-1.19) family adaptability, having more than five residents in the home (RR = 1.07; 95%CI: 1.01-1.14) and having used a private dental service during the last appointment (RR = 1.08; 95%CI: 1.03-1.13).

CONCLUSION

Family functioning and socio-demographic factors influence the level of oral health literacy among adolescents.

Cross-cultural adaptation of the Clear Communication Index to Brazilian Portuguese

OBJECTIVE

To perform a cross-cultural adaptation of the Clear Communication Index instrument from the Centers for Disease Control and Prevention (CDC-CCI) from English to Brazilian Portuguese.

METHODS

This study comprised initial discussion about the conceptual equivalence of the instrument by a committee formed by experts on health education. We performed translations, synthesis of translations, back-translations, revision by the committee, and linguistic revision. Semantic equivalence was obtained by analyzing the referential and general meaning of each item by the committee, resulting in a pre-final version of the instrument. Subsequently, thirty professionals with health sciences degrees performed a pre-test. These professionals used the pre-final version of the instrument to assess a health education material. A questionnaire was applied to evaluate the acceptability of the instrument, the understanding of each of the 20 items, as well as the individual and professional variables. We analyzed the scores attributed to the health education material, the variables related to healthcare professionals, the proportions of the acceptability of the instrument, and the comprehension of each item.

RESULTS

After we obtained the conceptual equivalence of the instrument, the committee of experts, the instrument’s main author, and the linguist produced the pre-final version using two translations, a synthesis of the translations, and two back-translations. A general equivalence was maintained in 15 of the 20 items (75%), four of the items were slightly altered (20%), and one item was very altered (5%). Nineteen items presented referential equivalence or near equivalence (95%). We then carried out with the pre-test, in which the professionals used the pre-final version. Two items in the domains of “risks” and “main message” were unclear and needed to be revised.

CONCLUSION

The process of cross-cultural adaptation of the Clear Communication Index provided an adapted version to the Brazilian Portuguese language.

What Has Changed in the Dental Prosthesis Procedures in Primary Health Care In Brazil?

The study aimed to identify the changes in the provision of dental prosthetics procedures in the Brazilian primary care. Secondary data from the Brazilian "National Programme for Improving Access and Quality of Primary Care" was assessed and three similar questions related to dental prostheses execution that were answered by the same 9,698 oral health teams, in 2011/2012 and 2013/2014, were compared. There was a 4.3% increase in the number of teams that identified individuals with prosthetic needs; a 0.8% increase in the number of teams that performed impression for prosthetic purposes; and the number of teams that reported performing dental prostheses consultations increased by 0.6%. Overall, there was a small modification in the number of teams that provided dental prosthesis procedures in Brazil.

A national study on the use of opioid analgesics in dentistry

The aim of this study was to assess the frequency of opioid analgesics prescribed by Brazilian dentists, potential regional differences and their association with socioeconomic and health-related factors. Data for all opioid prescriptions by dentists was obtained from the 2012 database of the National Controlled Substances Management System, regulated by the Brazilian Health Surveillance Agency. The number of defined daily doses (DDD) and DDDs per 1,000 inhabitants per day for each Brazilian state were calculated as the primary outcomes. DDDs were compared by regions and Brazilian states. Spearman's rho correlation coefficient was used to determine the influence of the states' characteristics, such as the Human Development Index; poverty; education; number of dentists per 100,000 inhabitants; visit to the dentist; dental care plan; good or very good oral health; number of pharmaceutical establishments per 100,000/inhabitants; and ability to get all prescribed medications. Data analysis was performed using IBM SPSS Statistics 25.0. A total of 141,161 prescriptions for opioids analgesics by 36,929 dentists were recorded, corresponding to 658,855 doses of opioids dispensed in 2012. The most commonly dispensed opioids were codeine associated with paracetamol (83.2%; n = 117,493). The national DDDs per 1,000 inhabitants per day was 0.0093 (range: 0.0002-0.0216). DDD per 1,000 inhabitants per day was positively associated to visits to dentists (rs = 0.630; P < 0.001) and inversely associated to poverty (rs = -0.624; p = 0.001). There are significant differences in opioid prescriptions in dentistry among the Brazilian states. These differences may be associated with non-clinical factors.

Assessing a possible vulnerability to dental caries in individuals with rare genetic diseases that affect the skeletal development

Background

Individuals diagnosed with a rare genetic disease that affects skeletal development often have physical limitations and orofacial problems that exert an impact on oral health. The aim of the present study was to analyze the possible vulnerability to dental caries in individuals with rare genetic diseases that affect skeletal development.

Methods

A paired cross-sectional study was carried out with a sample of 140 individuals [70 with rare genetic diseases affecting skeletal development: mucopolysaccharidosis (MPS) (n = 29) and osteogenesis imperfecta (OI) (n = 41) and 70 without rare diseases] and their parents/caregivers. The participants in the first group were recruited from two reference hospitals specialized in rare genetic diseases in the city of Belo Horizonte, Brazil. All participants were examined for the evaluation of breathing type, malocclusion, dental anomalies, oral hygiene and dental caries. The parents/caregivers answered a structured questionnaire addressing the individual/behavioral characteristics and medical/dental history of the participants. Statistical analysis involved the chi-square test and multiple logistic regression analysis for the dependent variable (dental caries) (α = 5%). This study received approval from the Human Research Ethics Committee of the Universidade Federal de Minas Gerais.

Results

The mean age of the individuals was 10.34 ± 6.55 years (median: 9.50 years). Individuals with inadequate oral hygiene were 4.70–fold more likely to have dental caries (95% CI: 2.13–10.40) and those with the rare genetic diseases (MPS/OI) were 2.92-fold more likely to have dental caries (95% CI: 1.38–6.17).

Conclusion

Individuals with inadequate oral hygiene and those with MPS and OI had a greater chance of belonging to the group with dental caries. Based on the present findings, individuals with the rare genetic diseases may be considered vulnerable to caries.

Understanding oral health care team performance in primary care: A mixed-method study

Objective

This study aims to describe the primary care services carried out by Oral Health Teams (OHTs) in Brazil, and to understand the nuances that lead to different levels of OHT performance.

Material & methods

A mixed-methods study with a sequential explanatory design was developed. In the quantitative phase, secondary data from a national survey (PMAQ-AB) was used to describe the work of 12,403 OHTs. Item response theory (IRT) was applied, to evaluate the psychometric qualities of 20 oral health questions from PMAQ-AB and to identify the performance of OHT. The quantitative results guided the selection of the qualitative sample. An extreme case sampling strategy was used (opposite results). OHTs were selected from Belo Horizonte metropolitan region in Brazil using scores measured by IRT. Data were collected through semi-structured interviews. Data analysis was conducted using deductive and inductive thematic analysis.

Results

Quantitative results showed that there are OHT with high and low performance in Brazil. The IRT analysis showed that items related to prostheses and oral cancer tend to discriminate high-performance OHTs from other OHTs. Qualitative results deepened the understanding of accessing oral health services and found several access barriers, such as the insufficient number of OHTs for the population, and a very long waiting time for dental consultations other than urgency. The qualitative results confirmed that high-performance OHTs tend to emphasize oral cancer surveillance and deliver prostheses in PHC services.

Conclusion

Despite the expansion of oral health in PHC in Brazil in recent years, OHTs still face many challenges such as: access barriers; failures in prevention, early diagnosis and follow-up of oral cancer cases; and insufficient rehabilitation with prostheses.

Qualidade do cuidado: Avaliação da disponibilidade de insumos, imunobiológicos e medicamentos na Atenção Básica em município de Minas Gerais, Brasil

Objetivo: Avaliar a Atenção Básica quanto aos insumos, imunobiológicos e medicamentos disponibilizados nos serviços de saúde da família de município de Minas Gerais, Brasil. Métodos: Trata-se de pesquisa transversal, analítica, conduzida em 2014, a partir de instrumento ministerial intitulado Autoavaliação para Melhoria do Acesso e da Qualidade da Atenção Básica, de equipes de saúde da família. Oito itens foram considerados, com valores entre zero a 10 pontos, da total inadequação à total adequação da Unidade Básica de Saúde (UBS), ao item avaliado. Classificaram-se as unidades em padrões de qualidade “muito insatisfatório” a “muito satisfatório” e analisou-se conforme localização rural e urbana, nível de significância p<0,05. Resultados: Participaram 75 equipes, que apresentaram expressiva inadequação nos itens: UBS dispor todas as vacinas exigidas no calendário básico, 5,95 (±4,003); possuir insumos e medicamentos para abordagem inicial de urgência/emergência, 2,33 (±2,500); apresentar os medicamentos básicos com regularidade, 3,68 (±3,146). A classificação foi regular para 45,3% das unidades e insatisfatória para 29,3%, sem diferenças quanto à localização urbana ou rural (p=0,479). Conclusão: Evidenciou-se avaliação insatisfatória, com inadequações relativas às vacinas, à abordagem inicial nas situações de urgência e emergência e à disponibilidade dos medicamentos. Tal situação prejudica o elenco de ações e a resolutividade dos serviços, afetando a capacidade da equipe para atender, efetivamente, as demandas de saúde da população

Analysis of the oral health care network development in Minas Gerais state, Brazil

OBJECTIVES

This study aimed to analyze the development stage of the oral health care network of the Brazilian Unified Health System in the state of Minas Gerais, Brazil.

METHODS

A cross-sectional descriptive and analytical study was conducted with 205 municipal oral health coordinators from the state. Data collection was carried out through a validated questionnaire to analyze the state of development of the oral health care network. Descriptive and cluster analysis were performed, and two clusters were generated.

RESULTS

The total median score of the questionnaires classified Minas Gerais as a state with incipient oral health care networks and a minimal capacity to operate such networks, reflected in the predominance of cluster 1 in the sample. There was no statistical association between age, time since graduation, and time spent working as a coordinator and the clusters (Mann-Whitney test). The coordinators' gender and educational level were also not statistically associated with the clusters (Pearson's chi-square and Fisher's exact, respectively).

CONCLUSION

There is a great need to improve the organization of services of the oral health care network in Minas Gerais. This can be done through improvements in its operational structure, as well as investment in management training.

Caries severity declined besides persistent untreated primary teeth over a 22-year period: Trends among children in Goiânia, Brazil

BACKGROUND

Evidence of time trends in early childhood caries in low- and middle-income countries in the second decade of the year 2000 is scarce.

AIM

To assess the trends in early childhood caries prevalence and severity in 2- to 5-year-old children over a 22-year period (1993-2015) in Goiânia, Midwest Brazil. Additionally, we aimed to investigate the changes regarding affected dental arches and teeth.

DESIGN

A time-lag analysis of trends in caries was carried out using data from three cross-sectional studies based on the World Health Organization diagnostic criteria, in 1993 (N = 1362), 2001 (N = 1620), and 2015 (N = 548).

RESULTS

Caries prevalence declined from 45.1% in 1993 to 29.0% in 2015. Prevalence of severe caries (dmft ≥ 6) in 2015 was nearly one-third of that found in 1993, and the SiC index (mean dmft of the highest tertile) decreased from 4.55 to 3.32. Decline was higher in the 1993-2001 than in the 2001-2015 time-lag. Posterior teeth and second molars had the greatest reductions. High proportions of untreated caries were found in all ages and survey years.

CONCLUSION

There were significant changes in caries prevalence and severity, marked by a striking decline from 1993 to 2001, followed by a less prominent decrease up to 2015, and high levels of untreated caries.

Association of breastfeeding and malocclusion in 5-year-old children: Multilevel approach

BACKGROUND

Breastfeeding plays an important role in child health, including the development of normal dental occlusion, but large epidemiological findings on the association breastfeeding-malocclusion are lacking.

AIM

To investigate the association between the proportion of breastfed children in the city level and the prevalence of malocclusion in the primary dentition at age 5.

DESIGN

This cross-sectional analysis used data from national population surveys on oral health and on breastfeeding practices. Data refer to 5278 5-year-old children and 44 Brazilian towns. Information on malocclusion and individual sociodemographic characteristics were obtained from the 2010 Brazilian Oral Health Survey. Breastfeeding rates during the first year of life were extracted from the Breastfeeding Prevalence Survey in Brazilian Towns. Population sociodemographic data were analysed as confounder. Multilevel Poisson analyses were performed.

RESULTS

Malocclusion prevalence was 63.3%. Towns exhibiting higher prevalence of breastfeeding among 9- to 12-month-olds presented lower prevalence of malocclusion among children at age 5 (PR 0.98; 95% CI 0.98-0.99).

CONCLUSIONS

Lower prevalence of malocclusion among 5-year-old children was associated with a higher proportion of children breastfed at ages 9 to 12 months at a city level, regardless of sociodemographic factors. These findings highlight the importance of encouraging breastfeeding during a child's first year.

A Survey About Dental Instruments at the Primary Health Care in Brazil

Abstract This study describes the structure of oral health services in primary health care in Brazil and the instruments available for the provision of oral health care and to compare the number of instruments according to organizational characteristics of health services and among the macroregions. Of the 23,251 oral health teams (OHTs) in the Public Health System, 17,513 (75.3%) participated in this study. Trained researchers observed the structures of the health services and determined the presence of and whether a sufficient quantity of 36 dental instruments existed. The score of each oral health service was determined by the sum of the number of dental instruments present in sufficient quantity (0 to 36). Central tendency measures were compared along with the variability in these scores according to the organizational characteristics of the services and according to the Brazilian macroregion. No instrument was found to be present in all evaluated services. Basic, surgical and restorative instruments were the most frequently found. Periodontal, endodontic and prosthetic instruments exhibited the lowest percentages. The mean and median numbers of dental instruments were higher for teams that operated over more shifts, those with an oral health technician and those in the South and Southeast regions. The oral health services were equipped with basic, surgical and restorative instruments. Instruments designed for periodontal diagnosis, emergency care and denture rehabilitation were less frequently found in these services. The worst infrastructure conditions existed in the OHTs with the worst forms of care organization and in regions with greater social issues.

Evaluating Psychometric Properties of an Instrument Addressing Comprehensiveness of Care Among Dentists

This study aimed to evaluate the psychometric properties of an instrument to assess comprehensiveness of care from dentists using a combination of classical test theory and item response theory. A 46-item instrument was developed and tested by a panel of experts, followed by a pilot test and administration to 187 primary care dentists in a large Brazilian city. The 46 items were evaluated using the following criteria: acceptability, internal consistency, temporal stability, inter-item correlation, and tetrachoric correlation. This evaluation led to a shortened version consisting of 11 items that met all the criteria previously described. The temporal stability was measured using Cohen's kappa, and all 11 items presented values greater than 0.5. The Cronbach's alpha value was 0.72. None of the 11 items had missing data on the distribution of responses, and the model considering the discrimination as varying fit the data better than the model considering discrimination as a constant parameter (p<0.001). Item characteristic curves showed that 54.5% of items could be considered difficult, i.e., only dentists with a good understanding of comprehensiveness responded favorably. The 11-item instrument to assess comprehensiveness of care by dentists is considered to have good psychometric properties.

Impact of untreated dental caries severity on the quality of life of preschool children and their families: a cross-sectional study

PURPOSE

Untreated dental caries is a persistent oral problem among preschool children. Although there is vast evidence regarding the impact of dental caries on oral health-related quality of life (OHRQoL) in this age group, evidence on the impact of untreated caries severity is scarce. The purpose of this study was to investigate the impact of untreated caries severity on the OHRQoL of preschool children and their families.

METHODS

A cross-sectional study was conducted with 563 individuals in the city of Goiania, Brazil. Data were collected through interviews with parents/caregivers and clinical examinations of their children. The OHRQoL was measured by the Brazilian version of the Early Childhood Oral Health Impact Scale. Untreated dental caries severity was assessed using validated indices. Other independent variables were socioeconomic, toothache prevalence, and the questionnaire respondent. Statistical analysis involved bivariate comparisons and Poisson regression analyses.

RESULTS

A higher prevalence of impact on OHRQoL was found among preschool children with untreated dental caries with clinical consequences (PR 1.31; 95% CI 1.01-1.70) compared to those without caries; those aged 5 years (PR 1.47; 95% CI 1.18-1.82), compared to those aged two; and those with a toothache (PR 1.54; 95% CI 1.34-1.76), compared to those without toothache. Moreover, fathers (PR 0.71; 95% CI 0.55-0.92) and other respondents (PR 0.70; 95% CI 0.52-0.96) perceived less impact on the OHRQoL in comparison to mothers.

CONCLUSIONS

Severe untreated dental caries with clinical consequences had a negative impact on the children's OHRQoL, regardless of toothache and socioeconomic factors.

Healthy and cariogenic foods consumption and dental caries: A preschool-based cross-sectional study

OBJECTIVE

To evaluate the association of the consumption of healthy and cariogenic foods with the prevalence of untreated dental caries among preschool children.

MATERIALS AND METHODS

A cross-sectional study was conducted with 427 5-year-old preschoolers. Caries was evaluated through a clinical examination using dmft index. Parents/guardians answered a questionnaire addressing socioeconomic status, eating frequency, and oral hygiene habits.

RESULTS

The prevalence of untreated caries was 51%. The multiple models demonstrated a seven percent increase in the prevalence of untreated caries with each additional daily contact with cariogenic foods, whereas a four percent reduction in this prevalence rate was found for each additional contact with healthy foods. When the number of daily contacts with cariogenic and healthy foods was incorporated into the same model, the former reached only borderline statistical significance (p = 0.05), whereas the latter maintained an association with lower caries rates (p = 0.01).

CONCLUSION

A dietary assessment based solely on the frequency of the consumption of cariogenic foods may not be sufficient to understand the occurrence of dental caries in preschool children. It is necessary a more comprehensive evaluation of the dietary pattern, once a healthy diet can present an association with lower prevalence of caries even among preschool children who consume cariogenic foods.

Comparative study of oral and salivary parameters in patients with and without loss of bone mass

Osteoporosis is an insidious and increasingly prevalent disease that can cause fractures and affect patients' quality of life. The current study comparatively evaluates patients with and without loss of bone mass in terms of salivary calcium, viscosity, and pH. A controlled cross-sectional study was conducted in two groups of 32 postmenopausal women subjected to a bone densitometry scan and later referred for dental management at the Federal University of Minas Gerais, Brazil. The patients were assigned to two groups: Group 1 - patients with low bone mineral density (BMD) and Group 2 - patients without bone mineral changes. The following salivary parameters were evaluated: calcium concentration, flow rate, viscosity, pH, and average total protein. An oral examination was performed for assessment of DMFT variables and tongue coating. Data were analyzed using descriptive and inferential statistics, adopting a p-value < 0.05. The patients' mean age was 60 years (± 7.35). Salivary flow, pH, and viscosity were similar among the groups. Average total protein was 14.8 mg/mL and 19.0 mg/mL in Groups 1 and 2, respectively. Tongue coating and salivary calcium levels were significantly higher in Group 1 (p < 0.001). Salivary calcium is an important screening tool and may eventually be used for the diagnosis of bone mineral changes.

Regional differences in infection control conditions in a sample of primary health care services in Brazil

International guidelines have pointed out the importance of the physical environment of health care facilities in preventing and controlling infection. We aimed to describe the physical environment of dental care facilities in Brazil in 2014, focusing on characteristics designed to control infections. Exactly 16,202 dental offices in the Brazilian Unified National Health System (SUS) participated in this survey. Trained researchers extracted information about the infection control characteristics of health facilities by using a structured instrument. We used data from 12 dichotomous questions that evaluated the wall, floor, sink and tap conditions, and the presence and condition of sterilization equipment. We calculated a score by summing the number of characteristics handled appropriately for infection control, which could range from 0 to 12. Hierarchical cluster analyses were developed. None of the 12 criteria were met by all the oral health teams. Only 208 (1.3%) dental offices correctly performed all 12-infection control practices. Two clusters, with different frequencies of structure for infection control in dental offices, were identified. South and Southeast regions had the highest frequencies for Cluster 1, with better structure of infection control in dental offices. Dental care facilities of oral health teams were not typically meeting the infection control guidelines regarding clinic design and equipment. Adherence to the guidelines varied among the Brazilian geographic regions.

Risk factors for dental caries in children with developmental disabilities

The aim of the present study was to investigate risk factors for dental caries in children with developmental disabilities who were treated at a clinical reference service for patients with special needs in Belo Horizonte, MG, Brazil. This is a retrospective cohort study that evaluated 401 dental charts of individuals without dental caries or restorations in their first dental appointment. The dependent variable was the time of occurrence of new dental caries or restorations and was measured in months. Gender, age, International Code of Diseases (ICD), mother´s education, sugar consumption, use of fluoride toothpaste, oral hygiene, mouth breathing, reports of xerostomia, gingival status, use of psychotropic or asthma drugs, and history of asthma were covariates. The Cox proportional hazards regression model was used to estimate the raw and adjusted hazard ratios and their respective 95% confidence intervals. The average time that individuals remained free of dental caries/restoration was equal to 107.46 months (95%CI 95.41 to 119.51), with a median of caries-free children up to 94 months. For each point increase in the scale of sucrose consumption, the increase in caries risk was 1.07 (95%CI 1.01 to 1.15). Sucrose consumption was the only risk factor for dental caries found in this group of individuals with developmental disabilities.
