Do binge drinking adolescents have a greater number of traumatised teeth? A longitudinal study with 12-year-olds in Brazil.

BACKGROUND: Binge drinking has been linked to traumatic dental injury (TDI). Once drunk, adolescents are more prone to accidents, which may result in orofacial injury. AIM: This study evaluated the possible association of binge drinking with a number of traumatised teeth in a population of 12-year-old Brazilian adolescents in 2013 and 2015. DESIGN: This study was longitudinal, carried out with 588 adolescents at two moments, 2013 and 2015. TDI, overjet and lip protection were assessed by calibrated examiners. Binge drinking data were collected through the Alcohol Use Disorders Identification Test. Sociodemographic indicators were obtained through a questionnaire answered by the parents/guardians. The Poisson regression model with a random effects intercept was estimated. RESULTS: A higher prevalence of traumatised teeth was observed among adolescents who binge drink (IRR = 1.37; 95% CI: 1.05-1.80; p < .05). The prevalence was also significantly higher among adolescents in this age range with a ≥ 3-mm overjet and those with inadequate lip protection (IRR = 1.99; 95% CI: 1.44-2.76; p < .001 and IRR = 3.41; 95% CI: 2.57-4.53; p < .001, respectively). CONCLUSION: A greater number of traumatised teeth were found among adolescents who reported binge drinking and had severe overjet and inadequate lip coverage.

Association between shortened dental configurations and health outcomes: a scoping review.

This study mapped definitions of shortened dental configurations and health outcomes employed in association studies. A scoping review was conducted using the PubMed/Medline, Scopus, Web of Science, SciELO and Cochrane databases. Two trained researchers selected studies and extracted data. Studies that investigated the association between shortened dental configurations (exposure) and person-centered outcomes (general and oral health) related to health behavior (dietary patterns). Clinical outcomes were classified according to the International Classification of Functioning, Disability and Health and the International Classification of Diseases of the World Health Organization (WHO). Shortened dental configurations were defined as at least 20/21 teeth or the position of the teeth, including esthetics, dental occlusion and periodontal status (Eichner Index, Shortened Dental Arches, Functional Dentition Classification System, Posterior Occluding Pairs, Functional Tooth Units). The initial search resulted in 12,525 records in English, Portuguese and Spanish, 432 of which addressed the association of interest. General health (n = 203) and oral health (n = 201) were addressed in a similar number of studies. Most outcomes were related to general health (n = 184), the most frequent of which were endocrine, nutritional or metabolic diseases (n = 57) and mental functions (n = 26). Person-centered measures were addressed in 153 studies, most of which were about oral health and oral health-related quality of life (n = 62). Oral health outcomes were predominantly related to intake functions (n = 44) and diseases or disorders of the orofacial complex (n = 24). Dietary patterns (n = 43) and mortality (n = 38) were also studied. The cross-sectional design (n = 257) and non-probabilistic sampling (n = 218) were more frequent. The shortened dental configurations defined by the WHO were the most frequent in the studies (n = 206). The effects of shortened dental configurations have been investigated mainly in relation to endocrine, nutritional or metabolic diseases and measures of oral health-related quality of life. The findings point to a diversity of health outcomes assessed and substantial methodological variability.

Challenges to conducting research on oral health with older adults living in long-term care facilities.

BACKGROUND: The challenges to conducting oral health studies involving older people in long-term care facilities (LTCFs) must be debated. OBJECTIVE: This study aimed to investigate researchers' perceptions and experiences while conducting an epidemiological survey on oral health among older individuals residing in LTCFs. METHODS: A qualitative study was conducted involving six researchers who utilized field diaries to record their impressions during data collection through interviews (older individuals (or their proxies), caregivers, and LTCF coordinators) and oral examinations of the older people participants. Additionally, researchers responded to open-ended questions about their experiences. The collected material was subjected to content analysis by two researchers. RESULTS: The themes that emerged from the analysis were institutional context, aspects affecting the operationalization of the study, and data collection oriented by the clinical-functional profile of the older people. According to the researchers' perceptions, LTCF coordinators demonstrated concern for the study's benefits for older adults and the preservation of institutional routines during the research process. Caregivers emerged as vital sources of information, guiding researchers in navigating the challenges posed by the physical and mental complexities of the older people participants, necessitating empathy, sensitivity, and attentive listening from the researchers. The organization of materials and a streamlined data collection process proved essential for optimizing time efficiency and reducing stress for participants and researchers. CONCLUSION: The researchers recognized the important role played by LTCF coordinators and formal caregivers, underscoring the significance of empathetic methodologies and streamlined data collection processes in mitigating the challenges inherent to research conducted within LTCFs.

Bleaching effectiveness and cytotoxicity of new experimental formulation of niobium-based bleaching gel.

OBJECTIVES: The development of new bleaching agents with minimum concentration of hydrogen peroxide (HP), without adverse effects, and with bleaching effectiveness, has great clinical relevance. The aim of this study was to evaluate the bleaching efficacy and cytotoxicity of a new niobium-based bleaching gel, compared to already available HP-based gels. MATERIALS AND METHODS: For the bleaching efficacy analysis, 40 bovine incisors were randomly divided into 4 groups according to the established bleaching protocol: control, untreated; 35HP, 35% HP bleaching gel; 6HP, 6% HP bleaching gel; NbHP, niobium gel associated with 3% HP gel. The color variation was measured in a spectrophotometer and the values of ΔL, Δa, Δb, and ΔE obtained. For the cell viability assay by MTT, MC3T3 cells were exposed to bleaching gel extracts (1:500, 1:250, 1:125 dilutions; immediately and 24 h). Statistical tests were performed (P < 0.05). RESULTS: The color alteration for all bleaching gels was significant compared to control (P < 0.05), but the NbHP gel showed a significant ΔE than other gels, with expressive color alteration at 14 days (P < 0.05). The 35HP showed high cytotoxicity regarding control and the most groups in all periods and extracts analyzed (P < 0.05), while the NbHP showed greater cell viability than control in the immediate period, dilution of the 1:500 and superior to 6HP in the most extracts at 24 h. CONCLUSION: The new experimental niobium-based gel has bleaching efficacy similar to that of gels with a high concentration of HP, and it has high cytocompatibility. CLINICAL RELEVANCE: The use of this new generation of niobium-based whitening gel associated with a low concentration of hydrogen peroxide represents the possibility of a tooth whitening with lower dentin sensitivity.

Unraveling the signs and symptoms of oral conditions that affect daily life activities and oral health-related quality of life.

OBJECTIVES: Since oral conditions negatively affect oral health-related quality of life (OHRQoL), this study evaluated which oral clinical condition, signs, and symptoms are associated with the impact on OHRQoL, its domains, and specific daily life activities among adults. MATERIALS AND METHODS: Data from a probabilistic sample of adults (35-44 years old) was used. The Oral Impacts on Daily Performance (OIDP) was used to evaluate OHRQoL, its domains (physical, psychological, and social), and nine daily life activities. Signs and symptoms of oral diseases (dental caries, periodontal disease, need for dental prothesis, and tooth loss) and oral self-perception were considered. Descriptive, bivariate, and multi-level analyses were conducted. RESULTS: A total of 5,834 adults were included, of which 52.9% had some negative impact of oral conditions on OHRQoL. Difficulty in eating was the most affected daily life activity. For multiple models, dental caries lesions (cavities), filled teeth with caries, gingival bleeding, periodontal pocket, dental pain, need for upper or lower dental prosthesis, and oral health self-perception were associated (p < 0.05) with overall OHRQoL or at least one of its domains. The impact on daily life activities of each individual was associated with at least one oral condition. Dental caries lesions (cavity) and dental pain were associated (p < 0.05) with the impact on most daily life activities evaluated. CONCLUSIONS: Different signs and symptoms of prevalent oral diseases are associated with the impact on specific daily life activities among adults, which may compromise the OHRQoL. CLINICAL RELEVANCE: Knowledge of how signs, symptoms, and oral conditions affect OHRQoL and daily life activities can provide essential information for clinicians to establish proper disease management and preventive strategies focusing on improving patients' lives.

Intersectoral Collaboration to Promote Child Development: The Contributions of the Actor-Network Theory.

An integrated intersectoral care model promises to meet complex needs to promote early child development and address health determinants and inequities. Nevertheless, there is a lack of understanding of actors' interactions in producing intersectoral collaboration networks. The present study aimed to analyze the intersectoral collaboration in the social protection network involved in promoting early child growth and development in Brazilian municipalities. Underpinned by the tenets of actor-network theory, a case study was conducted with data produced from an educational intervention, entitled "Projeto Nascente." Through document analysis (ecomaps), participant observation (in Projeto Nascente seminars), and interviews (with municipal management representatives), our study explored and captured links among actors; controversies and resolution mechanisms; the presence of mediators and intermediaries; and an alignment of actors, resources, and support. The qualitative analysis of these materials identified three main themes: (1) agency fragility for intersectoral collaboration, (2) attempt to form networks, and (3) incorporation of fields of possibilities. Our findings revealed that intersectoral collaboration for promoting child growth and development is virtually non-existent or fragile, and local potential is missed or underused. These results emphasized the scarcity of action by mediators and intermediaries to promote enrollment processes to intersectoral collaboration. Likewise, existing controversies were not used as a mechanism for triggering changes. Our research supports the need to mobilize actors, resources, management, and communication tools that promote processes of interessement and enrollment in favor of intersectoral collaboration policies and practices for child development.

A systematic review of measurement instruments for oral health assessment of older adults in long-term care facilities by nondental professionals.

BACKGROUND: Regular oral health assessment of older adults living in Long-term Care Facilities (LTCF) can improve their oral health. AIMS: This study aimed to systematically review studies describing the development of instruments employed by nondental professionals to assess the oral health of older adults in LTCF and to evaluate their measurement properties. MATERIAL & METHODS: Electronic searches were conducted in the MEDLINE (PubMed), Embase, Web of Science, Scopus, and LILACS databases. Measurement properties of the identified instruments were evaluated using the Consensus-based Standards to select health Measurement Instruments (COSMIN) checklist. Studies assessing at least one measurement property (validity, reliability, or responsiveness) of instruments used to assess oral health of older adults living in LTCF by nondental professionals were considered. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) checklist was used to evaluate the quality of evidence. RESULTS: Fifteen studies reporting measurement properties of seven instruments were selected. The ohr-interRAI and the OHAT were considered to have sufficient content validity, with high and moderate evidence quality, respectively. OHAT, BOHSE, and DHI showed acceptable results on reliability but with very low quality of evidence. DHI and OHSTNP also showed acceptable results for criterion validity, but, with low quality of evidence, insufficient or unclear results were observed for the remaining measurement properties. Studies evaluating the validity criteria of BOHSE and hypotheses testing of ohr-MDS were considered to have high evidence quality. DISCUSSION AND CONCLUSION: The ohr-interRAI can be provisionally recommended for use until further evidence is provided. Further methodologically rigorous studies are needed to assess the measurement properties of the existing instruments.

Is Binge Drinking Associated with Suicidal Behaviors among Brazilian Adolescents?

OBJECTIVE: To evaluate the association between suicidal behaviors and binge drinking among Brazilian adolescents. METHODS: A cross-sectional study was conducted with 2,476 students 14 to 19 years of age from 26 public high schools in the city of Olinda, Brazil. Data collection occurred between March and June 2018 through the self-administered Youth Risk Behavior Survey. Descriptive analysis and Poisson regression (p < 0.05, 95%CI) were performed. RESULTS: The prevalence of suicidal ideation, planning and attempt in the previous 12 months was 23.7%, 17.4% and 13.5%, respectively. Suicidal ideation was associated with binge drinking one to two days (PR:1.053, 95%CI:1.011-1.096) and ≥ three days in the previous 30 days (PR:1.069, 95%CI:1.016-1.125), sadness/hopelessness in the previous 12 months (PR:1.313, 95%CI:1.267-1.360), a report of family physical aggression in the previous 12 months (PR:1.111, 95%CI:1.068-1.155), the female sex (PR:1.082, 95%CI:1.049-1.115) and a non-nuclear family (PR:1.037, 95%CI:1.004-1.071). Suicidal planning was associated with sadness/hopelessness in the previous 12 months (PR:1.257, 95%CI:1.214-1.302), report of family physical aggression in the previous 12 months (PR:1.110, 95%CI:1.065-1.156) and the female sex (PR:1.072, 95%CI:1.041-1.104). Suicide attempt was associated with binge drinking ≥ three days in the previous 30 days (PR:1.062, 95%CI:1.008-1.119), sadness/hopelessness in the previous 12 months (PR:1.202, 95%CI:1.161-1.244), report of family physical aggression in the previous 12 months (PR:1.105, 95%CI:1.060-1.153) and the female sex (PR:1.064, 95%CI:1.034-1.095). The Catholic (PR:0.938, 95%CI:0.899-0.979; PR:0.925, 95%CI:0.888-0.9865; PR:0.937, 95%CI:0.899-0.977) and Evangelical (PR:0.956, 95%CI:0.922-0.992; PR:0.954, 95%CI:0.919-0.991) religions acted as a possible protective factor against suicidal behaviors. CONCLUSIONS: Suicidal ideation and attempt were associated with binge drinking.

Trends of maxillofacial injuries resulting from physical violence in Brazil.

BACKGROUND/AIM: A large proportion of interpersonal violence results in maxillofacial injuries. The monitoring of maxillofacial injuries in the context of gender violence has been little explored. The aim of this study was to analyze trends in cases of maxillofacial injuries resulting from interpersonal physical violence considering the gender of the victim and perpetrator. MATERIALS AND METHODS: A time-series study was conducted. Data regarding maxillofacial injury cases due to interpersonal physical violence were collected from reports at a forensic institute of a city in northeastern Brazil, between 2008 and 2014 (84 months). Rates of interpersonal physical violence per 100 000 inhabitants were determined for each gender. A negative binomial regression model was used to evaluate trends. The cycle plot was used to investigate the occurrence of seasonality, considering subseries for each month. RESULTS: A total of 3561 reports were analyzed, revealing higher rates of female victims and male perpetrators throughout the series. There was no indication of seasonality. The annual percentage of injuries involving male victims reduced significantly by 6.8% (P < .001), while injuries involving female victims increased significantly by 4.5% (P = .002). Regarding perpetrators, rates remained constant over time, following the same pattern for both genders. CONCLUSIONS: The data demonstrate greater victimization involving maxillofacial injuries against women perpetrated more often by men, with a trend toward an increase in female victims and a reduction in male victims.

Education and income-based inequality in tooth loss among Brazilian adults: does the place you live make a difference?

BACKGROUND: Socioeconomic inequalities in tooth loss might be minimized or potentialized by the characteristics of the context where people live. We examined whether there is contextual variation in socioeconomic inequalities in tooth loss across Brazilian municipalities. METHODS: Data from the 2010 National Oral Health Survey of 9633 adults living in 157 Brazilian municipalities were used. The individual socioeconomic indicators were education and household income. At the municipal level, we used the Municipal Human Development Index (HDI) as our contextual indicator of socioeconomic status (low:< 0.699 versus high: > 0.70). The Relative (RII) and Slope (SII) Indexes of Inequality, Relative (RCI), and Absolute (ACI) Concentration Indexes were calculated to compare the magnitude of education and income-based inequalities among municipalities with low versus high HDI. Multilevel Poisson regression models with random intercepts and slopes were developed. RESULTS: At the individual level, adults with lower education & income reported more tooth loss. The mean number of missing teeth was 9.52 (95% CI: 7.93-11.13) and 6.95 (95% CI: 6.43-7.49) in municipalities with low and high HDI, respectively. Municipalities with high HDI showed higher relative and absolute education-based inequality. For income-based inequalities, higher SII and RCI was observed in municipalities with lower HDI. A significant cross-level interaction indicated that high-education adults reported fewer missing teeth when they lived in municipalities with high HDI compared to adults with the same education level living in low HDI municipalities. For individuals with the lowest education level, there was no difference in the number of teeth between those from municipalities with high and low HDI. CONCLUSIONS: There was a social gradient in tooth loss by education and income. Living in disadvantaged municipalities cannot overcome the risk associated with low schooling. The protective effect of higher education can be reduced when people live in disadvantaged areas.

Is reduced dentition with and without dental prosthesis associate with oral health-related quality of life? A cross-sectional study.

BACKGROUND: Oral health-related quality of life (OHRQoL) has important implications for the clinical practice of dentistry and dental research and should contribute to professional judgment about restorative treatments and prosthetic replacement in patients who had reduced dentitions. The aim was to compare the OHRQoL among adults (35-44 years) categorized according to different definitions of reduced dentition and considering the use (or non-use) of dental prosthesis. METHODS: This study used data from a probabilistic sample of adults in Sao Paulo, Brazil, 2015. OHRQoL was based on none items of Oral Impacts on Daily Performance (OIDP) index, as prevalence (at least one impact) and extent (the number of items with non-zero score). We used different criteria to assess dentition status: (1) Shortened Dental Arch (SDA): having 3-5 natural occlusal units (OUs) in posterior teeth and intact anterior region; (2) hierarchical functional classification system: a five-level stepwise classification of dentition; and (3) presence of ≥21 teeth. The use or nonuse of dental prosthesis was recorded. Negative binomial regression models involved the adjustment for social determinants of health. RESULTS: Nearly half (53.1%) of the 5753 participating adults had at least one oral health issue impacting OHRQoL. OIDP prevalence in adults with SDA did not differ from those with more OUs (PR = 1.02; 95%CI 0.91-1.13). Individuals with non-functional dentition had worse OHRQoL regardless of their use of a dental prosthesis. Adults with fewer than 21 remaining teeth, ranked significantly higher in OIDP extent, regardless of dental prosthesis use (PR = 1.38; 95%CI 1.16-1.63 with prosthesis; PR = 1.62; 95%CI 1.19-2.20 without dental prosthesis). CONCLUSIONS: Individuals with more missing teeth reported worse OHRQoL regardless of using a dental prosthesis. Preserving a functional dentition, even with missing teeth, is compatible with OHRQoL.

Longevity, effectiveness, safety, and impact on quality of life of low-concentration hydrogen peroxides in-office bleaching: a randomized clinical trial.

OBJECTIVE: The study evaluated the longevity, effectiveness, safety, and impact on the oral health-related quality of life of in-office dental bleaching using low-concentration hydrogen peroxides. MATERIALS AND METHODS: Randomized, parallel, and double-blinded clinical trial was performed with 54 participants using 6% or 15% hydrogen peroxide (HP) in-office bleaching activated via hybrid LED/laser light. Tooth color was evaluated at baseline (T1), 1 week of bleaching (T2), 2 weeks of bleaching (T3) and 1 week (T4) and 6 months (T5) after finishing the bleaching using the Classical Vita™ scale and spectrophotometer. Tooth sensitivity and gingival irritation were measured with Visual Numeric Scale and Modified Gingival Index. The impact on quality of life was evaluated using the Oral Impact on Daily Performance. The data were analyzed using the Friedman, Mann-Whitney, and McNemar tests (p < 0.05). RESULTS: The group HP15% presented significant color change (ΔE) from T1 to T4 (p = 0.002) and T1 to T5 (p < 0.001). Parameters L, a*, and b* differed significantly at T3, T4, and T5 compared T1 for both groups. At 6-month follow-up, 57.1% of HP6 and 43.7% of HP15% participants migrated from B1 to a darker color. No significant differences were observed between the groups in tooth sensitivity, gingival irritation, or impact on quality of life. CONCLUSIONS: Both agents showed bleaching effectiveness, but HP15% presented greater color stability than HP6%, at 6-month follow-up. The agents showed low levels of tooth sensitivity, gingival irritation, and did not affect the oral health-related quality of life of the participants. CLINICAL RELEVANCE: Despite the greater presence of sensitivity during treatment compared with 6% hydrogen peroxide, 15% hydrogen peroxide demonstrated better bleaching effectiveness, and greater color stability at the end of bleaching and at 6-month follow-up. The use of 15% hydrogen peroxide presents more suitable results.

Recognition of child physical abuse by a group of Brazilian primary care health professionals.

BACKGROUND: Child maltreatment is a complex social and public health problem. AIM: To evaluate the frequency of the recognition by Brazilian health professionals in primary care of child physical abuse (CPA) and associated factors. DESIGN: A representative cross-sectional study was conducted with dentists, nurses, family physicians, and pediatricians who participated in the network of the Family Health Strategy in the city of Belo Horizonte, Brazil. Data collection involved in the administration of a questionnaire validated for use in Brazil. Data were collected from 181 dentists, 235 nurses, 203 family physicians, and 96 pediatricians. RESULTS: Among the 715 health professionals, 499 (69.8%) had some type of postgraduate degree and 414 (57.9%) recognized suspected or proved cases of CPA. The recognition was associated with occupation, as pediatricians recognized 14.11-fold [OR = 14.11 (95% CI: 3.73 to 53.43)] more cases of CPA compared with dentists. The recognition was also associated with a longer period of time working in the city [OR = 2.79 (95% CI: 1.24 to 6.29)]. CONCLUSION: The recognition of cases was positively associated with the longer working time in the municipal network and with pediatricians. The dentist was the category that was least associated with the recognition of CPA.

Mothers' perception about health education in brazilian primary health care: A qualitative study.

BACKGROUND: Health education actions are strategic actions aimed at health promotion. Moreover, better health education practices have been linked to comprehensive care developed by primary health services. AIM: To understand the perception of mothers about the health education developed by the Primary Health Care (PHC) services. DESIGN: We adopted a qualitative research approach, conducted using semi-structured interviews, and assuming, as the theoretical reference, the attributes derived from PHC. Pregnant women and mothers of children under 1 year old attended by Brazilian Family Health teams were included. RESULTS: Eight pregnant women and twelve mothers of children under 1 year of age participated in the study. These mothers perceive educational actions as necessary only for primiparous mothers. They value the guidance of informal networks and maternity hospitals to the detriment of primary services, and they do not adhere to care that conflicts with their previous knowledge. The evidence shows that the educational actions of the primary health services do not adequately respond to the attributes of community orientation, family focus, and cultural competence. CONCLUSION: It is necessary to modify the educational practices in order to incorporate and value the existing knowledge in the territory, thereby adapting the care guidelines to the local context.

Correction to: User satisfaction with public oral health services in the Brazilian unified health system.

Following publication of the original article [1], the authors have reported that there is an error in Table 2 - Distribution of users concerning satisfaction with oral health services: the categories 'No' and 'Yes' should swap places.

User satisfaction with public oral health services in the Brazilian Unified Health System.

BACKGROUND: User satisfaction represents a patient-centered measure that should be used to assess the quality of oral health services. This study investigated the differences in user satisfaction with public oral health services according to the sociodemographic user profile and the quality of oral health services in primary health care in Brazil. METHODS: Secondary data from a national program obtained through interviews with users were analyzed. Satisfaction was based on the Swan' model relating to perceptions regarding the service performance, assessment of overall satisfaction and the intention to avoid the service in the future. The exploratory variables were demographic characteristics of the users and the quality of the primary service from the user's viewpoint, considering the dimensions: access; receptivity of spontaneous demand; integral health care; bonding, accountability, and coordination of care. RESULTS: A total of 37,262 users participated, and 65.51% reported satisfaction with the oral health service, that was higher among those > 20 years old and beneficiaries of the Family Grant Program and lower among users with a higher level of schooling and those who reported being employed. Users who rated oral health service positively were more satisfied. CONCLUSIONS: Socioeconomically disadvantaged user was more satisfied with oral health services and the satisfaction increased with age. The improvement in the quality of oral health services in primary care can result in greater satisfaction.

Influence of surface treatment on the performance of silorane-based composite resin in class I restorations: a randomized clinical trial.

OBJECTIVES: The aim of this study was to evaluate the clinical performance of silorane-based composite restorations applied after different surface treatments. MATERIALS AND METHODS: This controlled and randomized clinical trial included 26 patients with class I restoration indications. The teeth were randomly assigned to the following treatments: control 1/G1, silorane specific self-etching adhesive (P90 self-etch primer and bond) + silorane-based composite resin (Filtek™ P90 low shrink posterior restorative); G2, 37% phosphoric acid + silorane specific self-etching adhesive + silorane-based composite resin; G3, blasting with aluminum oxide + silorane specific self-etching adhesive + silorane-based composite resin; and control 2/G4, self-etching adhesive (Adper™ SE Plus self-etch adhesive) + dimethacrylate-based composite resin (Filtek™ P60 posterior restorative). The clinical performance was evaluated at baseline and after 1 year. RESULTS: A total of 141 restorations were made and evaluated. For all clinical criteria evaluated, no significant difference was found between the surface treatments at baseline and after 1 year (p > 0.05). After 1 year, only the group with 37% phosphoric acid + silorane specific self-etching adhesive (G2) showed a significant reduction in marginal adaptation (p < 0.05). CONCLUSION: In general, all surface treatments showed an adequate clinical performance for silorane-based composite resin in class I restorations. However, a reduction in the marginal adaptation after 1 year was found when additional phosphoric acid etching was used prior to silorane specific self-etching adhesive. CLINICAL RELEVANCE: The use of phosphoric acid etching prior to specific self-etching adhesive can adversely affect the marginal adaptation of silorane-based restorations.

Traumatic dental injuries in Brazilian children and oral health-related quality of life.

BACKGROUND/AIMS: Population-based studies that investigate the impact of TDI on oral health-related quality of life (OHRQoL) among school children and its association with socioeconomic factors are scarce and offer conflicting results. The aim of this study was to evaluate the impact of TDI on OHRQoL among school children and its association with socioeconomic status. MATERIALS AND METHODS: A cross-sectional study was conducted with 588 12-year-old children enrolled in public and private schools in the urban areas in the city of Diamantina (southeastern Brazil). Clinical examinations were performed for the diagnosis of traumatic dental injury based on Andreasen's classification. The Child Perceptions Questionnaire (CPQ11-14 ), which has been validated for the population in Brazil, was employed to evaluate oral health-related quality of life. Socioeconomic status and overjet were also analyzed. Statistical analysis involved the chi-square test and logistic regression. RESULTS: A total of 29.4% of the students exhibited some type of trauma to at least one tooth. A negative impact on oral health-related quality of life was found in 53.1% of the sample. Traumatic dental injury was associated with a high impact on oral health-related quality of life [OR = 1.61 (95% CI: 1.08-2.39)] and overjet >3 mm [OR = 5.42 (95% CI: 3.66-8.02)]. However, no statistically significant associations were found between TDI and socioeconomic status. CONCLUSIONS: Prevalence of traumatic dental injury was high among the children who participated in the study, and it was associated with a high impact on oral health-related quality of life as well as overjet >3 mm.

Dependence on others for oral hygiene and its association with hand deformities and functional impairment in elders with a history of leprosy.

OBJECTIVE: To analyse the frequency of dependence on others for oral hygiene and its association with hand deformities, frailty and dependence on others for basic activities of daily living (BADL) among elders with a history of leprosy. BACKGROUND: Dependence on others for oral hygiene has not been considered in multifunctional geriatric assessments. MATERIAL AND METHODS: Edentulous elders with a history of leprosy who used complete dentures and resided in a former leprosy colony were classified as independent or partially/completely dependent on others for brushing their dentures or rinsing and for BADL, and as frail or robust. The presence of hand deformities was assessed by an occupational therapist. RESULTS: 28.4% and 14.9% were completely/partially dependent on others for brushing and rinsing, respectively. The dependence for BADL was observed in 21.6% and hand deformities in 17.6%. A higher odds of dependence for brushing/rinsing was found among elders who were dependent on others for BADL. Brushing dependence (61.5%) was more frequent among participants with hand deformities than those without this condition (21.3%) (OR: 6.8; 95% IC: 1.2-37.9; P = .028). There was no association between frailty and brushing (P = .068) or rinsing (P = .202) dependence. CONCLUSION: Approximately one-third of elders have a dependence on others for brushing; a smaller proportion is dependent on others for rinsing. Older people who are dependent on others for BADL and who present hand deformities are more likely to be dependent on others for denture brushing and rinsing. Elders may perform oral self-care even when they present frailty.

Influence of functional dentition on satisfaction with oral health and impacts on daily performance among Brazilian adults: a population-based cross-sectional study.

BACKGROUND: Dental esthetics, chewing and speech should be preserved in a dentition denominated functional and are closely related to satisfaction with oral health (SOH), impacts caused by oral problems and have a possible association with Oral Health-Related Quality of Life. Thus, the purpose of the present study was to investigate the influence of different concepts of functional dentition (FD) on both SOH and impacts on daily performance (IDP) among Brazilian adults. METHODS: A cross-sectional study was conducted with 9564 adults (35-44 years). SOH and IDP were evaluated using the Oral Impacts on Daily Performance (OIDP) questionnaire. FD was considered based on four different definitions: I-classification of the World Health Organization (FDWHO = ≥20 teeth); II-well-distributed teeth (WDT = ≥10 teeth in each arch); III-classified by esthetics and occlusion (FDClass5 = sequential presence of one tooth in each arch, ≥10 teeth in each arch, 12 anterior teeth, ≥three posterior occluding pairs [POPs] of premolars and ≥one POP molar bilaterally); and IV-classified by esthetics, occlusion and periodontal status (FDClass6 = FDClass5 plus all sextants with CPI ≤ 3 and/or CAL ≤ 1). The proportion of adults satisfied with oral health and without overall impact (OIDP = 0) was calculated for each definition of FD. Multiple Poisson regression models were adjusted by demographic-socioeconomic characteristics, self-reported oral problems and the use of dental services for each dependent variable. RESULTS: When FDClass5 and FDClass6 were considered a greater proportion of adults reported being satisfied (52.1 and 53.1%, respectively) and have OIDP = 0 (52.4 and 53.3, respectively). In the multiple models, SOH was associated with FDClass5 (RP = 1.21) and FDClass6 (RP = 1.24) and OIDP = 0 was associated with WDT (RP = 1.14) and FDClass6 (RP = 1.21). CONCLUSIONS: The greater influence of WDT, FDClass5 and FDClass6 on aspects related to quality of life in comparison to FDWHO demonstrates the need for the establishment of a broader definition of FD that encompasses subjective aspects.
