title: Prevalence of oral health-related shame and associated factors among Brazilian schoolchildren

description: Abstract The aim of the present study was to investigate the prevalence of oral health-related shame and the associated factors among 8-to-10-year-old Brazilian schoolchildren. A cross-sectional study was conducted with 388 children randomly selected from public and private schools of Diamantina, southeastern Brazil. In order to identify the feeling of shame, self-reports were collected through a single question, “In the last month, did you feel ashamed because of your teeth or mouth? Two calibrated examiners performed the clinical examination for dental caries (DMFT/dmft index), traumatic dental injuries (O’ Brien), and malocclusion (Dental Aesthetic Index). Sociodemographic indicators were obtained through a questionnaire answered by the children’s caregivers. Descriptive analysis, chi-square test, and hierarchical Poisson regression models were performed (95%CI; p &lt; 0.05). The prevalence of shame was 38.1% (n = 148). The adjusted regression analysis demonstrated a significant association between shame and untreated dental caries (PR: 1.34; 95%CI: 1.04–1.74; p = 0.02), age of 10 years (PR: 1.36; 95%CI: 1.05–1.76; p = 0.01), and with parents with less than eight years of schooling (PR: 1.30; 95%CI: 1.00–1.68; p = 0.04). Older children with untreated dental caries and whose parents had lower education level presented a higher prevalence of oral health-related shame.

title: Use and need of removable dental prostheses in an institutionalized Brazilian elderly population: a cross-sectional study

description: Abstract The aim of this study was to assess the use and need of conventional removable prostheses (total and partial) and their associated factors among institutionalized elders. A cross-sectional study was conducted with 1003 elderly people living in non-profit private long-term care institutions in Belo Horizonte, Brazil. Inclusion criteria required a minimum Mini Mental State of Examination (MMSE) score of 21. After the test, 191 individuals were included. Oral examination and interviews were conducted to identify participants’ use (throughout the day/every day) and need (do not have/have but do not use) of removable dental prostheses. Socioeconomic health indicators and behaviours were collected from institutional records and via interviews. Bivariate analysis was performed using chi-square test (p&lt;0.05). Poisson regression with robust variance was used in multivariate analysis. Most elders were female (76.4%) and independent in their daily activities (56.5%). Elderly men (PR 1.26) and those whose dental visit was more than one year ago (PR 1.38) showed higher need of dental prostheses. Elderly women (PR 1.68) and individuals with morbidities (PR 1.33) had higher prostheses use. This study demonstrates how socio-demographic characteristics, health indicators, and oral health services impact the use and need of dental prostheses among elders and how these can contribute to public oral health policy development.

title: Rural-urban differences in oral health among older people in Southern Brazil

description: Abstract This study aimed to assess the association between oral health and rurality in an older Brazilian population. Population-based samples of 1,451 urban and 411 rural elders were obtained from two databases. Several oral health and related measures, including the number of teeth lost, use of dental prostheses, dental visits, self-reported oral health, and perceived need for a dental prosthesis, were compared. Oral health-related information was obtained by a trained research team with interviews conducted in the individuals’ homes. Regression models were used to verify the association between living in rural areas and oral health outcomes after adjusting for possible confounding factors. The elderly population mostly comprised of women in rural or urban areas, and the mean age was 70 years in both locations. Less-educated individuals (without or with complete elementary schooling) were more common in rural regions than in urban areas. After adjustment for socioeconomic characteristics, living in rural areas was associated with a lower perceived need for dental prostheses (PR 0.68, 95% CI 0.56–0.84), poor self-reported oral health (OR 1.24; 95% CI 1.05–1.46), and having fewer teeth (β -1.31; 95% CI -2.18 to -0.45). The place of residence had a significant impact on oral health indicators, with rurality negatively influencing oral health. These findings suggest that preventive and curative strategies for dental services may be needed for the Brazilian rural population.

title: Effect of educational strategy combined with ART on oral health-related quality of life: a controlled clinical trial

description: Abstract This study aimed to assess whether complementing atraumatic restorative treatment (ART) with oral health educational strategies (OHES) improves the perception of oral health-related quality of life (OHRQoL) and clinical oral outcomes. A controlled clinical trial included 93 six- to eight-year-old students from five public schools of Piracicaba, Saltinho, and Charqueada municipalities (State of São Paulo, Brazil) divided into 3 groups (31 children each) which received: OHES (caries-free), ART (dental caries), and ART plus OHES (dental caries). OHRQoL (CPQ8-10-ISF:16), dental caries, biofilm control, and gingivitis were assessed before and 1 month after interventions by one calibrated examiner. OHES consisted of an educational interactive activity performed once a week for four weeks. Data were analyzed using mixed model ANOVA, Chi-square, and Sign tests. After 1 month of follow-up, improvement in gingivitis status, OHRQoL total score, and Functional Limitations, Emotional Well-Being and Social Well-Being domains scores were found in all groups (p &lt; 0.05). The improvement in biofilm control was observed only in the OHES group (p &lt; 0.001; power = 0.98), while a decrease in Oral Symptoms scores was observed only in ART+OHES group (p &lt;0.001; power = 0.99) and a significant change in the perception of oral health was observed in the two groups that received ART (p &lt; 0.05). In conclusion, improvement in overall OHRQoL and oral status was observed in all children, although the effect of including health educational strategies in the treatment plan was determinant for the perception of an improved oral health after restorative treatment.

title: Effect of xylitol varnishes on enamel remineralization of immature teeth: in vitro and in situ studies

description: Abstract We evaluated the efficacy of xylitol varnishes on the remineralization of newly erupted permanent and deciduous teeth in vitro and in situ. Human enamel specimens were randomly allocated to 8 groups (n = 15/group). Artificial caries lesions were produced and enamel alterations were quantified by surface/subsurface hardness and transverse microradiography. The blocks were then treated with the following varnishes: DuraphatTM; 20 wt% xylitol (146 μm) varnish; 20 wt% milled xylitol (80 μm) varnish, and placebo varnish, and removed after 6 h of immersion in artificial saliva. In vitro the blocks were subjected to pH-cycles for 8 days. In situ fifteen subjects wore palatal appliances containing four pre-demineralized and treated enamel specimens, for 5 days. Data were statistically analyzed by ANOVA/Tukey and Kruskal-Wallis/Tukey’s test (p &lt; 0.05). The %SHR in both studies was significantly increased by xylitol and Duraphat™ varnishes when compared to placebo. Considering subsurface remineralization, only the xylitol varnishes were able to significantly reduce the enamel lesion. Xylitol varnishes can be promising alternatives to promote enamel remineralization of newly erupted permanent and deciduous teeth.

title: Frailty and oral health-related quality of life in community-dwelling older adults: a cross-sectional study

description: Abstract Poor oral health has been associated with frailty among older adults. However, limited evidence has been available on whether frailty can affect oral health-related quality of life (OHRQoL) in older adults. This study aimed to investigate the relationship between frailty and OHRQoL among community-dwelling older adults. A household-based cross-sectional study involving community-dwelling older adults aged 65 years and older was conducted in the city of Bauru, Brazil. Data on frailty status, sociodemographic characteristics, self-perceived dental care needs, and OHRQoL (OHIP-14) were collected through individual interviews. The use of and the need for total dental prostheses were assessed through clinical examinations. Logistic regression was used to determine whether frailty status and covariates were associated with OHRQoL prevalence measures (OHIP-14 total score ≥ 1 and OHIP-14 fairly/very often ≥ 1). The sample comprised 334 participants, among whom 58.7% and 41.3% were between 65–74 and 75–102 years old, respectively. The prevalence of moderate to severe frailty was 12.3%. Moderate to severe frailty (OR = 4.49; 95%CI 1.29–15.66), the need for lower dental prosthesis (OR = 2.20; 95%CI 1.27–3.81), and self-perceived dental care need (OR = 3.90; 95%CI 2.14–7.14) were associated with OHIP-14 total score ≥1. Moderate to severe frailty (OR = 2.95; 95%CI 1.33–6.55), being female (OR = 2.24; 95%CI 1.34–3.75), and self-perceived dental care need (OR = 4.80; 95%CI 2.86–8.03) were associated with OHIP-14 fairly/very often ≥1. Overall, our results showed that moderate to severe frailty was significantly associated with poor OHRQoL in community-dwelling older adults.

title: Guided neural regeneration with autologous fat grafting and oxygen hyperbaric therapy

description: Abstract The loss of continuity of the nerve structure interrupts the transmission of nerve impulses and leads to the disorganization of functional activities. Many methods, as the use of neurogenic factors, aid in the process of neural regeneration by accelerating or improving peripheral nerves neoformation. The adipose tissue is abundant in the human body, and it has presented promising results in the regeneration of peripheral nerves. We carried out a randomized controlled study in 9 months, using 45 male Wistar rats, 80 days old, and the sciatic nerve was chosen for analysis. The control animals were divided into three groups – Initial group (IG), Final group (FG), and denervated group (DG) – with seven animals each. The experimental groups, with twelve animals each, were polyethylene tube filled with fat (EGF) and polyethylene tube without filling (EGwf). All groups, except IG, were submitted to 10 sessions of hyperbaric oxygen treatment of 1h 45 min in alternating days. Functional evaluation by walking-track was assessed using the Catwalk XT® software and tissues were harvested and stained with 1% toluidine blue for histological analysis. Quantitative data were first analyzed with the Kolmogorov Smirnov normality test. Comparison between the four groups was analyzed by ANOVA followed by Tukey Test. We concluded that hyperbaric oxygen therapy had positive results on morphometric and functional parameters. However, no significant differences were found regarding the use of autologous fat graft.
