Pain, anxiety, and catastrophizing among pregnant women with dental pain, undergoing root canal treatment.

This prospective study aims to evaluate dental pain, anxiety, and catastrophizing levels in pregnant women undergoing root canal treatment. Sixty pregnant and non-pregnant women presenting dental pain and an indication for root canal treatment were included in the study. Dental anxiety and catastrophizing were investigated using validated questionnaires. The endodontic intervention was performed, and a numerical scale measured preoperative and postoperative dental pain. The results were analyzed using STATA software 12.0. Unadjusted analyses assessed the association between pregnancy and pain, anxiety, and catastrophizing levels. Multiple linear regression models using 'forward stepwise' entry procedures were used to assess the independent effects of variables on pain scores. The significance level was set at 0.05. Initially, most patients experienced intense dental pain. The levels of dental pain, dental anxiety, and catastrophizing did not differ between pregnant and non-pregnant women. Logistic regression showed that postoperative pain was associated with irreversible pulpitis diagnosis (OR = 4.78; 95%CI 1.55-13.55) and high catastrophizing levels (OR = 1.96; 95%CI 1.01-3.84). Preoperative and postoperative pain rates and anxiety and catastrophizing were similar between pregnant and non-pregnant patients. Postoperative pain was associated with irreversible pulpitis diagnosis and high catastrophizing levels. The similarity between pregnant and non-pregnant women regarding preoperative and postoperative dental pain and catastrophizing and anxiety levels supports the indication of root canal treatment during the gestational period whenever necessary.

Undergraduate dental students' perceptions of dental pain in children - A grounded theory study.

INTRODUCTION: There is an underuse of pain management strategies in dental care for children, possibly owing to perceived stress and discomfort when treating children, which has also been reported by dental students. The aim of this study was to explore how undergraduate dental students experience and understand pain related to dental treatment in children. MATERIALS AND METHODS: Interviews were held with 21 Swedish dental students, from 3 dental schools, all in their final 2 years of education. The interviews were transcribed verbatim and analysed according to Grounded Theory. RESULTS: A core category, seeking guidance to avoid pain, was identified and related to 6 conceptual categories. The students used different strategies to manage pain prevention in child dentistry and to become skilled dentists. They described high levels of stress, as well as having high expectations on themselves when treating children. The stress led to a surface learning approach, something the students were not fully aware of. CONCLUSION: All children should have the right to be ensured optimal pain prevention in dental care. The basis for this is laid during undergraduate education. Thus, pain management in child dentistry is an area in need of special attention in this respect. The academic staff has an important role in supporting their students in their process to gain an identity as professional dentists. To ensure that students incorporate an understanding of the importance of pain prevention when treating children there is a need to create more integration between theory and clinical training in undergraduate education.

Untangling the truth: User engagement with misinformation in toothache-related Facebook posts.

OBJECTIVE: Social media is a platform for sharing views on aspects of life, including oral health. This study aimed to characterize Facebook posts related to toothache information. METHODS: Two independent investigators retrieved 500 English-language posts with the highest level of interaction using CrowdTangleTM and analyzed their facticity, motivation, author's profile, content, sentiment, and type of post. Data were analysed descriptively and using Pearson's Chi-square and Mann-Whitney U tests and multiple logistic regression models. RESULTS: Most posts were produced by regular users and were not financially motivated, although commercial posts had significantly higher total interaction among users. While link- or video-containing posts (OR = 1.66) and posts with positive sentiments (OR = 1.53) were associated with users' total interaction, older (OR = 1.81) and link- or video-containing posts (OR = 2.04) were associated with overperforming scores. Misinformation was positively associated with financial motivation (OR = 2.03) and positive sentiments (OR = 3.79). CONCLUSION: This study highlights the importance of addressing the spread of misinformation related to oral health on social media and taking steps to ensure that accurate and reliable information is readily available. Toothache-related misinformation was associated with positive sentiments and financial motivation. Links, videos, and positive sentiments awakened greater user engagements with toothache-related posts.

Individual and Contextual Factors Associated with Adolescents' Self-Perceived Need for Treatment.

The present study aimed to investigate associations between the self-perceived dental treatment need and clinical factors, familial characteristics, and school context in adolescents. A cross-sectional study was conducted with a representative sample of 746 students aged 15 to 19 years in a medium-sized city in Brazil. Data collection involved the use of a sociodemographic questionnaire, an oral health questionnaire, and the Family Adaptability and Cohesion Scales (FACES III) instrument. Clinical examinations were performed by two trained and calibrated examiners (Kappa > 0.80) using the Nyvad criteria. A robust logistic regression analysis for complex samples was performed using a multilevel approach (α = 5%). The individual factors associated with the self-perceived treatment need were dental pain (OR = 1.08; 95% CI: 1.01-1.16), the loss of the first molars (OR = 1.09; 95% CI: 1.03-1.15), and disengaged family cohesion (OR = 1.15; 95% CI: 1.01-1.31). In terms of context, attending a public school was associated with the self-perceived treatment need (OR = 1.17; 95% CI: 1.02-1.33). Thus, the individual factors of toothache, tooth loss, and a disengaged family, as well as the school context, exerted an influence on the self-perceived treatment need.

Relationships among barodontalgia prevalence, altitude, stress, dental care frequency, and barodontalgia awareness: a survey of Turkish pilots.

Background: Gas expansion in body cavities due to pressure changes at high altitudes can cause barodontalgia. This condition may compromise flight safety. Aim: To investigate relationships among barodontalgia awareness, dental visit frequency, and barodontalgia prevalence in civilian and military pilots operating at high altitudes. Materials and Methods: Civilian pilots from Turkish Airlines and military pilots from the Turkish Air Force, flying between November 2022 and January 2023, participated in this study. A 20-question survey was administered to 750 pilots, covering topics such as barodontalgia awareness, dental visit frequency, breaks after dental treatments, in-flight pain, and pain type and severity. The voluntary surveys were distributed by email. Results: Of the 750 pilots, 526 completed the survey; 61% were aware of barodontalgia, and 81% of pilots who had experienced it reported pain at altitudes <2000 feet. The study revealed higher barodontalgia awareness among pilots who had experienced it, with the highest prevalence among jet pilots. Pilots with barodontalgia also showed a higher frequency of dental visits (p < 0.001). Additionally, this group reported more frequent interruption of flight due to dental treatment (IFDT), more problems experienced in flights after treatment (PFAT), and higher instances of bruxism or teeth clenching during flight, suggesting stress and anxiety (p < 0.05). Conclusions: Barodontalgia, a type of pain linked to stress, significantly impacts pilot performance, and can threaten flight safety, even at lower altitudes. Thus, there is a need to educate pilots about stress management, barodontalgia awareness, and the importance of regular dental check-ups.

Impact of Coronavirus disease 2019 on patients with toothache: Analysis of tweets on Weibo.

OBJECTIVE: The aim of this study is to investigate the impact of Coronavirus disease 2019 (COVID-19) on toothache patients through posts on Sina Weibo. METHODS: Using Gooseeker, we searched and screened 24,108 posts about toothache on Weibo during the dental clinical closure period of China (February 1, 2020-February 29, 2020), and then divided them into 4 categories (causes of toothache, treatments of toothache, impacts of COVID-19 on toothache treatment, popular science articles of toothache), including 10 subcategories, to analyze the proportion of posts in each category. RESULTS: There were 12,603 postings closely related to toothache. Among them, 87.6% of posts did not indicate a specific cause of pain, and 92.8% of posts did not clearly indicate a specific method of treatment. There were 38.9% of the posts that clearly showed that their dental treatment of toothache was affected by COVID-19, including 10.5% of the posts in which patients were afraid to see the dentists because of COVID-19, and 28.4% of the posts in which patients were unable to see the dentists because the dental clinic was closed. Only 3.5% of all posts were about popular science of toothache. CONCLUSIONS: We have studied and analyzed social media data about toothache during the COVID-19 epidemic, so as to provide some insights for government organizations, the media and dentists to better guide the public to pay attention to oral health through social media. Research on social media data can help formulate public health policies.

Evaluation of the efficiency of antibiotics in treating adult patients with symptomatic apical periodontitis: A protocol for systematic review and meta-analysis.

BACKGROUND: When a person feels dental pain, it brings great discomfort and damages the quality of life. Symptomatic apical periodontitis is identified as the most frequent cause that triggers dental pain. Symptomatic apical periodontitis arises from an infection or inflammation in the pulpless root canal structure. According to clinical guidelines, the primary form of therapy for such teeth entails removing the inflammation or infection source through local surgical procedures. Presently, systemic antibiotics are recommended only for cases where there is clear indication of an infectious spread or a systemic involvement. Therefore, this study aims to assess the efficacy and level of safety of using antibiotics to treat adult symptomatic apical periodontitis patients. METHODS: The present protocol study will conduct a search on electronic databases to look for randomized controlled trials (RCTs) that have evaluated the effectiveness and safety of antibiotics when used to treat adult patients with symptomatic apical periodontitis. The databases will be search from their beginning to April 2021. The search is not bound by publication status or language restrictions. The following databases will be searched: Web of Science, PubMed, the Cochrane Library, Chinese National Knowledge Infrastructure, and EMBASE. This study will employ ZETOC Conference Proceedings and OpenGrey to identify potential grey literature. Afterwards, 2 independent authors will select the studies, extract data from the studies, and conduct a risk assessment to check for bias. All discrepancies between the authors will be resolute via discussion involving a third independent author. The data synthesis and statistical analysis of this study will be done with the RevMan software (Version: 5.3). RESULTS: The present protocol report will provide high-quality evidence related to the efficacy and level of safety when using antibiotics to treat mature symptomatic apical periodontitis patients. CONCLUSION: The outcomes of the present study will update the evidence available for assessing the efficacy and safeness of using antibiotics to treat mature symptomatic apical periodontitis patients. ETHICS AND DISSEMINATION: This study does not require an ethical approval since individual patient data is not included in any form.

Structural equation modelling of the complex relationship between toothache and its associated factors among Indonesian children.

The Indonesian family life survey (IFLS) is used for formulating various government policies. Our preliminary study using data from the IFLS showed increase in the prevalence of toothache from 2007 to 2014. Hence, a need to analyse the factors associated with toothache using structural equation modelling (SEM) for identifying the direct and indirect association of factors with toothache was evident. The objective of this study is to analyse the complex relationships between toothache and its associated risk factors. This cross-sectional study was conducted on the data obtained from the IFLS in 2014. The IFLS data pertaining to toothache and its prevalence were analysed using the STATA software, and the multifaceted relationship was analysed using SEM. The prevalence of toothache among Indonesian children was 15.55% (1,959 of 12,595). SEM showed the direct association between toothache and age (p < 0.001) and parent awareness of children's health conditions (p < 0.005) and food consumption frequency (p < 0.001). Parents' education level and residential area showed an indirect association with toothache, mediated by socio-economic status and parent awareness of children's health conditions (p < 0.001). We identified the multifaceted relationship between toothache and the social covariates. Parents' awareness of their children's health conditions mediated several indirect associations, highlighting its importance.

Odontogenic Infection and dental Pain negatively impact Schoolchildren's Quality of Life.

The aim of this study is to assess the prevalence of odontogenic infection in low-income Brazilian schoolchildren and evaluate its association with the subjective variables of oral health-related quality of life and dental pain. In this cross-sectional study, 230 schoolchildren aged eight to ten years old underwent a clinical oral survey in which the DMFT/dmft and PUFA/pufa indexes were measured. Afterward, children responded individually to the Child Perceptions Questionnaire (CPQ8-10) and self-reports of dental pain were collected. Data were statistically analyzed using MannWhitney or Kruskal-Wallis test with a post-test by Dunn's and Pearson correlation. Of the children evaluated, 42.6% had odontogenic infection and 80% reported experiencing dental pain. Children's age (p = 0.034) and past experience of dental pain (p < 0.002) were associated with odontogenic sepsis, in addition to impairment of their emotional well-being (p = 0.008), social welfare (p = 0.009) and overall impact on quality of life (p = 0.019). Toothache intensity (p < 0.001), frequency (p < 0.001) and duration (p < 0.001) were correlated to the overall impact on children's quality of life. The prevalence of odontogenic infection remains high among low-income Brazilian schoolchildren. Pediatric infection and its related pain induce not only various biological disorders but also impair children's self-perception of quality of life.

O objetivo deste estudo foi avaliar a prevalência de infecção odontogênica em crianças escolares brasileiras de baixa renda e analisar a sua associação com as variáveis subjetivas da autopercepção de qualidade de vida relacionada à saúde bucal e dor dentária. Neste estudo transversal, 230 crianças escolares com 8 a 10 anos de idade realizaram exame clínico bucal no qual os índices CPO-D/ceo-d e PUFA/pufa foram mensurados. Com isso, as crianças responderam individualmente ao Child Perceptions Questionnaire (CPQ8-10) e relatos de dor dentária foram coletados. Os dados foram estatisticamente analisados utilizando-se o teste Mann-Whitney ou Kruskal-Wallis, com posterior teste da correlação de Dunn e Pearson. Dentre as crianças examinadas, 42,6% apresentavam infecção odontogênica e 80% reportou experiência de dor dentária. A idade (p=0,034) e experiência de dor dentária (p<0,002) das crianças foram associadas à infecção odontogênica, bem como o seu bem-estar emocional (p=0,008) e social (p=0,009) e impacto geral na qualidade de vida (p=0,019). Além disso, a intensidade (p<0,001), frequência (p<0,001) e duração (p<0,001) da odontalgia foram correlacionadas com o impacto geral na qualidade de vida da criança. A prevalência de infecção odontogênica permanece elevada em crianças escolares brasileiras. Infecção pediátrica e sua dor relacionada induzem não apenas diversas desordens biológicas, mas também afetam negativamente a auto-percepção de qualidade de vida das crianças.

Mode of delivery alters dental pulp nociception and pain-induced changes in cognitive performance in adults male rats.

This study examined the effects of delivery mode on the response to inflammatory pulpal pain and pain-induced changes in cognitive performance in adult rats. Experiments were done on rats born by vaginal or caesarean section (C-section) delivery. Dental pulp was irritated by intradental capsaicin (100 µg) application and then nociceptive scores were recorded for 40 min. Spatial and passive avoidance learning and memory were assessed using the Morris water maze (MWM) and shuttle box tools, respectively. Additionally, in vivo recording of field excitatory postsynaptic potential (fEPSP) in the CA1 of the hippocampus was used to verify synaptic plasticity. Capsaicin produced more significant nociceptive behavior in vaginally delivered rats compared to C-section rats (P < 0.01). C-section-delivered rats show better performance in both MWM and shuttle box tests. Likewise, C-section rats had greater fEPSP slopes compared to the vaginally delivered group (P < 0.05). Capsaicin impairs cognitive performance in rats born by each delivery route. However, capsaicin effects were more significant in rats delivered vaginally than by C-section. Overall, C-section-delivered rats show lower sensitivity to capsaicin-evoked pulpal nociception and better cognitive performance than vaginally delivered rats. These effects are in part mediated by reduced neuroinflammation and enhanced neuronal synaptic plasticity following C-section delivery.

Assessment of the impact of toothache, untreated caries and its consequences on the quality of life among poor Brazilian children / Avaliação do impacto da dor de dente, da cárie não tratada e suas consequências na qualidade de vida de crianças brasileiras

Purpose: to evaluate the impact of dental pain and the consequences of untreated dental caries on the quality of life in children of low social-economic status aged from 8 to 10 years old. Materials and Methods: in this cross-sectional study, 230 children were submitted to a clinical examination in which the caries-pufa ratio was measured, afterward, they answered to two questionnaires: one about their quality of life (CPQ8-10) and the other about dental pain. Data were statistically analyzed through Chi-square, Mann-Whitney or Kruskal-Wallis tests to evaluate the association between the variables with impact on children's OHRQoL. To establish the existence of risk factors among variables and impact on OHRQoL a Poisson Regression model was applied. Results: dental caries (p = 0.003; PR 2.39; 95% CI 1.04­1.56), severity of untreated caries (p = 0.008; PR 2.86; 95% CI 1.13­2.00), toothache (p < 0.001; PR 2.31; 95% CI 1.64­3.27) and PUFA + pufa index (p < 0.023; PR 2.68; 95% CI 1.10­1.87) were associated with and were a predictor factor for impact on overall OHRQoL. All of these variables also had an effect over the social welfare subscale (p ≤ 0.001), whereas caries presence was also statistically linked with the emotional wellbeing subscale (p = 0.008) and dental pain with all four subscales (p ≤ 0.001). Conclusion: untreated dental caries' clinical consequences and dental pain exerted a negative influence on the quality of life of schoolchildren analyzed.(AU)

Objetivo: avaliar o impacto da dor de dente e das consequências da cárie não tratada na qualidade de vida de crianças entre 8 e 10 anos com baixos indicadores socioeconômicos. Métodos: neste estudo transversal, 230 crianças escolares foram submetidas a um exame clínico, no qual foram avaliados seus CPO/ceo (Dentes cariados, perdidos e obturados) e PUFA/pufa (Envolvimento pulpar, ulceração, fístula e abscesso). Em um segundo momento, elas responderam a dois questionários: um sobre a qualidade de vida (CPQ8-10) e outro sobre odontalgia. Os dados foram analisados estatisticamente por meio dos testes de Chi-quadrado, Mann-Whitney ou Kruskal-Wallis, para avaliar a associação entre as variáveis e o impacto na qualidade de vida relacionada à saúde oral (QdVRSO) da criança. Para estabelecer a existência de fatores de risco para impacto na QdVRSO entre as variáveis, um modelo de regressão de Poisson foi aplicado. Resultados: a presença de cárie (p = 0,003; RP 2,39; 95% IC 1,04-1,56), a severidade da cárie não tratada (p = 0,008; RP 2,86; 95% IC 1,13-2,00), dor de dente (p < 0,001; RP 2,31; 95% IC 1,64-3,27) e PUFA/pufa (p < 0,023; RP 2,68; 95% IC 1,10- 1,87) foram associados com impacto na QdVRSO, assim como também foram fatores preditores para o impacto na qualidade de vida relacionada à saúde oral. Todas as então citadas variáveis também exerceram efeito sobre a subescala do bem-estar social (p ≤ 0,001), enquanto a presença de cárie esteve estatisticamente conectada com a subescala do bem-estar emocional (p = 0,008) e a dor dentária com todas as subescalas da QdVRSO (p ≤ 0,001). Conclusão: as consequências clínicas da cárie não tratada e a dor dentária exercem uma influência negativa na qualidade de vida das crianças analisadas.(AU)

Differences in the Clinical Characteristics of Persistent Idiopathic Facial Pain (Atypical Odontalgia) Patients with or Without Neurovascular Compression of the Trigeminal Nerve.

BACKGROUND: Persistent idiopathic facial pain (PIFP) is the unexplained pain along the territory of the trigeminal nerve, including nonorganic tooth pain called atypical odontalgia (AO). Though PIFP is debilitating to patients' livelihood and well-being, its pathophysiology remains poorly understood. Although neurovascular compression (NVC) of the trigeminal nerve is known to be associated with trigeminal neuralgia (TN), the relationship between NVC and other orofacial pains has not been fully elucidated. METHODS: In this study, we investigated the differences in the characteristics of PIFP (primarily AO) patients in the presence or absence of NVC. A retrospective analysis was performed on data from 121 consecutive patients who had been diagnosed with unilateral PIFP according to the criteria of the International Classification of Headache Disorders (ICHD)-3 and underwent magnetic resonance imaging scans of the head. RESULTS: In the group without NVC, characteristic findings were significant for psychiatric morbidity, somatization, and pain disability, when compared with the group with NVC. Furthermore, the group without NVC exhibited significant headache, noncardiac chest pain, shortness of breath, and pain catastrophizing. CONCLUSIONS: These results suggest that PIFP patients can be divided into two groups: one consistent with a neuropathic pain phenotype when NVC is present and a functional somatic symptom phenotype when presenting without NVC. Our findings may enable a more precise understanding of pathophysiology of PIFP and lead to better treatment strategies.

Chronic migraine headache and multiple dental pathologies causing cranial pain for 35 years: the neurodental nexus.

We report a case that illustrates how chronic migraine headaches and multiple dental pathologies caused severe and long-standing cranial pain that affected the quality of life of a man for more than 35 years. His case was investigated at several settings including the neurology outpatient clinic of the hospital without a definitive diagnosis or resolution. After investigations, multiple oral pathologies including two occult dental abscesses were diagnosed. Once both affected teeth and associated abscesses were surgically removed, with subsequent antibiotic therapy the headaches resolved.

Evaluation of pain perception during orthodontic debonding of metallic brackets with four different techniques.

OBJECTIVE: The aim of this study was to evaluate patients' pain levels during four different debonding procedures. The null hypothesis was that the pain perception of the patients undergoing four different debonding applications was not statistically significant different. MATERIAL AND METHODS: One hundred and twenty orthodontic patients who underwent orthodontic debonding were included in this study. The patients were randomly divided into 4 groups according to technique used in the patients. Debonding groups were as follows: Group 1) Conventional debonding group, Group 2) Medication group (acetaminophen was given 1 hour before debonding), Group 3) Soft bite wax group, and Group 4) Soft acrylic bite wafer group. The patients' levels of anxiety and fear of pain were evaluated before debonding, and Numerical Rating Scale (NRS) was applied to evaluate their pain perception during debonding. Mann-Whitney U and Kruskal-Wallis tests were used to evaluate non-normally distributed data. Categorical data analysis were carried by chi-square and McNemar tests. The significance level was set at p<0.05. RESULTS: Anxiety scores of the patients were not statistically significant between both genders and debonding groups. In the quadrants in which the patients were perceived, the highest pain level was in the left side of the mandible. The teeth in which the highest pain level was perceived were the lower left and upper right lateral incisors. Although there was no statistically significant difference among the pain scores of the patients in each group, quadrant scores of female patients showed significant differences, being the lowest scores in the soft bite wax group. CONCLUSIONS: Majority of the patients had no fear of pain before debonding. Pain levels of the patients in the conventional debonding group were not significantly different from those of the other groups, except quadrant scores of females in the soft bite wax group. The null hypothesis was accepted.

Jaw Exercise Therapy and Psychoeducation to Reduce Oral Parafunctional Activities for the Management of Persistent Dentoalveolar Pain.

Objective: To retrospectively analyze the effects of our original combination therapy treatment on patients with nonodontogenic persistent dentoalveolar pain. Methods: Twenty-one patients suffering from persistent dentoalveolar pain (nineteen females and two males; mean age ± standard deviation: 55.7 ± 19.6 years) participated in this study. They were treated with a therapy combination of jaw exercise and psychoeducation to reduce oral parafunctional activities every month. The intensity of pain in these subjects was evaluated using a numerical rating scale (NRS) before and after treatment. Results: The NRSs at the baseline ranged from 5 to 10 (median, 8), from 0 to 10 (median, 2) at one month after treatment, from 0 to 10 (median, 1) at three months after treatment, and from 0 to 10 (median, 0) at the end of treatment. Pain intensity after treatment improved significantly. Conclusion: There was a significant reduction in pain after our combination of therapies as nonpharmacological treatments, and therefore this treatment could be useful in the management of NPDP patients.

Association between beliefs about medicines and self-medication with analgesics among patients with dental pain.

Self-medication with analgesics in dental pain management is a common practice as most of these medicines are available over-the-counter (OTC). The study aims to examine the relationship between beliefs about medicines and self-medication with analgesics in dental pain management in Malaysia. This cross-sectional study was conducted among conveniently sampled patients attending dental clinics, located in Kuala Lumpur, Malaysia to assess association between self-medication with analgesics and patient's beliefs about medicines via Beliefs about Medicines Questionnaire. Participants were evaluated for their self-medication practices via 4 items. Further assessment was done via Quantitative Analgesic Questionnaire (QAQ) regarding the analgesics taken. Statistical analyses were performed using SPSS version 24, with 0.05 as level of significance. The prevalence of self-medication with analgesics was 29.4%, with 95.6% of the participants took analgesics when necessary. Participants practising self-medication for dental pain reported more positive beliefs in General-Necessity (13.04 vs. 9.98, p = 0.001) than those not practising self-medication. However, these participants had weaker beliefs in General-Harm (12.00 vs. 10.29, p = 0.006) and General-Overuse (11.38 vs. 10.31, p = 0.032) than those not practising self-medication. Participants beliefs in General-Harm (r = -0.243; p = 0.003) and General-Overuse (r = -0.203; p = 0.012) were negatively correlated with total QAQ point. The study found that individuals who practised self-medication had stronger beliefs about the benefits of medicines and weaker beliefs in viewing medicines as harmful and overused. Findings can guide public education to improve the safety aspects of self-medication with analgesics in dental practice.

Impact of Caries Severity/Activity and Psychological Aspects of Caregivers on Oral Health-Related Quality of Life among 5-Year-Old Children.

The aim of the present study was to evaluate the influence of the severity/activity of dental caries as well as sense of coherence (SOC) and locus of control (LOC) on oral health-related quality of life (OHRQoL) among 5-year-old children. A cross-sectional study was conducted involving 769 children at schools in a city in northeast Brazil. Parents/caregivers answered validated questionnaires addressing SOC and LOC. The children and parents/caregivers answered their respective modules of the Brazilian version of the Scale of Oral Health Outcomes for 5-year-old children (SOHO-5). Data were also collected on sociodemographic characteristics, visits to the dentist, and the occurrence of toothache. Clinical examinations were performed by 2 trained examiners. A directed acyclic graph was used to select covariates for statistical adjustment, and logistic regression for complex samples was used to test associations between the dependent and independent variables (α = 5%). For parents/caregivers, the variables associated with a negative impact on OHRQoL were the occurrence of toothache (odds ratio, OR: 10.53; 95% confidence interval, CI: 6.34-17.51; p < 0.001) and a low SOC (OR: 2.17; 95% CI: 1.37-3.43; p = 0.001). According to the children's perceptions, the following variables were associated with a negative impact on OHRQoL: toothache (OR: 3.58; 95% CI: 2.30-5.55; p < 0.001), caries activity (OR: 1.97; 95% CI: 1.07-3.62; p = 0.028), and traumatic dental injury (OR: 1.71; 95% CI: 1.15-2.53; p = 0.007). Among parents/caregivers, a low SOC led to poorer OHRQoL. For the children, however, neither psychological aspect affected OHRQoL. In the perception of both the parents/caregivers and children, toothache was the oral condition that exerted a negative impact on OHRQoL.

Effect of dental pain and caries on the quality of life of Brazilian preschool children.

OBJECTIVE: To investigate the impact of dental pain on daily performances among five-year-old Brazilian children. METHODS: The study used data of 7,280 five-year-old children participating in the 2010 Brazilian Oral Health Survey (SBBrasil 2010 Project). Children were clinically examined and their parents or carers were interviewed at their homes. The outcome was the prevalence of the oral impacts on daily performance, and the explanatory variable was dental pain in the last six months. Other independent variables were children's gender and skin color/race, family income, household overcrowding, and caries experience (dmft). Rao-Scott test and Poisson regression for complex samples were carried out. RESULTS: The prevalence of impacts on daily performances was 26.1% (95%CI 22.3-30.2). Significant associations were found between the outcome and pain, caries experience, and sociodemographic variables. After adjusting for the independent variables, only pain and caries remained significant. Impacts on daily performances were more frequent among children with pain (PR = 1.14, 95%CI 1.06-1.23) compared to those without pain. Children with low dmft (PR = 1.90, 95%CI 1.39-2.60) and those with high dmft (PR = 3.53, 95%CI 2.78-4.49) had a higher prevalence of impact than those with no caries experience. CONCLUSIONS: Dental pain and caries had strong negative impacts on the five-year-old children's daily performances regardless of their demographic and socioeconomic characteristics.
