Traditionally removed mandibular central incisors and oral health-related quality of life: a cross-sectional study among adolescents in Maasai populated areas, Northern Tanzania

BackgroundThe traditional removal of mandibular anterior teeth has been existing for many years in the Sub-Saharan African countries. This study aimed to assess the prevalence and sociodemographic distribution of traditionally removed mandibular central incisors (TRMCI) and its association with oral impact on daily performance (OIDP) among adolescents in Maasai populated areas in the Northern part of Tanzania.MethodsUsing a two-stage cluster sample design, with schools as the primary sampling unit, 23 out of 66 eligible rural schools were randomly selected. From each selected school, one class, expected to contain adolescents aged 12–14 years, was identified. The students from these selected classes were invited to participate in the study. A total of 989 adolescents were invited and 906 (91.6%) accepted to participate and completed both an interview and a clinical oral examination.ResultsMean age was 13.4 years (12–17 years, SD 1.2) and 43.9% were males (n = 398). The participants from Longido district amounted to 47.1%. The Maasai group constituted 79.6% of the study participants. The frequency of the participants missing at least one mandibular central incisor were 18.5%. Multivariable logistic regression revealed that adolescents from Longido district were more likely to report at least one TRMCI (OR = 2.5, 95% CI 1.4–3.3). Adolescents from non-Maasai group were less likely to have atleast one TRMCI compared to adolescents from Maasai ethnic group (OR = 0.02, 95% CI 0.002–0.15). Adolescents with at least one TRMCI were more likely to report impacts on OIDP (OR = 3.3, 95% CI 1.9–5.7) than those without TRMCI. Independent of the TRMCI status, adolescents from Longido district were less likely than their counterparts to report oral impacts (OR = 0.4, 95% CI 0.2–0.6). Similarly, adolescents from non-Masaai group were more likely than their counterparts to report oral impacts (OR = 2.2, 95% CI 1.4–3.5).ConclusionTRMCI is common among adolescents in the Maasai populated areas in the Northern part of Tanzania and strongly associated with the district of residence and Maasai ethnicity and has a negative impact on oral health related quality of life. There is a need for oral health education in the rural Maasai communities in Tanzania to increase awareness of the negative consequences of this practice.

Evaluating complete silage for goat feeding in Gorontalo, Indonesia

Forage shortages and inconsistent quality in developing countries pose significant challenges to the small ruminant sector. Feeding ruminants with conserved forages is crucial to address this issue and ensure successful ruminant management in developing countries. The use of sorghum crops mixed with grasses as fermentation feed has gained thought because of its high protein efficiency, relatively high digestible energy, and total digestible nutrients. Therefore, this study aimed to determine feed intake, nutrient digestibility, and growth performance in Gorontalo local goats fed complete silage with varying levels of mixed concentrations of sorghum straw with grasses. Sixteen male Gorontalo local goats were preferred from the local area and randomly divided into four groups using a completely randomized design (CRD). Over 84 days, four different complete silage diets (T1, T2, T3, and T4) were given to goats. The goats' daily nutrient intake, digestibility, and growth performance were analyzed. The T1 diet consisted of 30% grass and 60% sorghum straw, the T2 diet included 20% grass and 70% sorghum straw, the T3 diet contained 10% grass and 60% sorghum straw, and the T4 diet had no grass and 90% sorghum straw. The study found that the dry matter intake (DMI) of goats ranged from 330.2 to 335.1 g/day, approximately 3% of their body weight. The digestibility values of dry matter, crude protein, crude fat, neutral detergent fiber, acid detergent fiber, and energy decreased as the amount of sorghum straw in the silage rations increased. The average daily gain (ADG) (gr/day) in T1, T2, T3, and T4 was affected, with T1 showing the highest ADG (43.2) and T4 showing the lowest (40.3). The Feed Conversion Ratio (FCR) value was also influenced, with T1 and T2 showing the best FCR (7.8 and 7.7) and T3 showing the worst (8.2). Based on these findings, it is recommended to limit the amount of sorghum straw to 60%-70% in complete silage for local goats in Gorontalo, especially in tropical areas where goats are common and sorghum is readily available.

Global perspective on child and adolescent oral health: a systematic review and meta-analysis of oral impacts on daily performance.

Several prevalence studies have estimated the region-specific impact of oral diseases on oral health-related quality of life. However, none of them reported and compared the same from a global perspective. This meta-analysis aims to evaluate pooled epidemiologic data about child-oral impacts on daily performance (C-OIDP) globally. A search was conducted in PubMed, Science Direct, SciELO, Semantic scholar, and Cochrane databases upto January 2023. Studies evaluating OIDP among 11-18-year-olds were included in the review. Quality of the included studies was evaluated using the health states quality index for cross-sectional studies. The meta-analysis used R package software version 4.3.0. A common effect model was used to calculate the pooled prevalence. The protocol was registered in the PROSPERO (CRD-NIHR) database with Reference ID CRD42023393798. The systematic literature search yielded 257 unique citations. After screening titles and abstracts, 214 irrelevant citations were excluded, leaving 55 for full-text review. Overall, 43 studies from 23 countries were included. The meta-analysis reported a pooled prevalence impact C-OIDP of 53.36% (CI: 52.78-53.95, 43 studies, 16,622 participants). The prevalence of C-OIDP scores among South America, Asia, Europe, Africa and Oceania was 83%, 63%, 58%, 33% and 47%, respectively. The maximum prevalence was reported in South America while the least prevalence was noted in the African population. Oral diseases affect the oral health-related quality of life of more than half of children and adolescents globally. Huge variations were noted in the prevalence of oral impacts across different regions. These findings can be utilized by policymakers to draft measures required for reducing impacts of oral diseases and improving the health-related quality of life.

Effects of High-Intensity Interval Training on Muscle Strength for the Prevention and Treatment of Sarcopenia in Older Adults: A Systematic Review of the Literature.

Sarcopenia is a significant health concern primarily affecting old adult individuals, characterized by age-related muscle loss, and decreased strength, power, and endurance. It has profound negative effects on overall health and quality of life, including reduced independence, mobility, and daily activity performance, osteoporosis, increased fall and fracture risks, metabolic issues, and chronic diseases like diabetes and cardiovascular conditions. Preventive strategies typically involve a combination of proper nutrition and regular physical activity. Among strength training exercises, high-intensity interval training (HIIT) stands out as the most effective approach for improving muscle function in older adults with sarcopenia. The current review identifies and summarizes the studies that have examined the effects of HIIT on muscle strength in older adults as an element of the prevention and treatment of sarcopenia. A systematic search using several computerized databases, namely, MEDLINE/PubMed, Scopus, SPORTDiscus, and Web of Science, was performed on 12 January 2023, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A total of 224 studies were initially retrieved. A total of five studies met the selection criteria. HIIT training shows improvements in body composition and functional and cardiorespiratory capacity, has benefits on muscle strength, increases muscle quality and architecture, and is associated with muscle hypertrophy in healthy older adults. Nonetheless, given the shortcomings affecting primary research in terms of the limited number of studies and the high risk of bias, further research is warranted.

Sociodemographic and Behavioural Factors Affecting the Oral-Health-Related Quality of Life as Measured with the Child-OIDP Index in Adolescents.

Environmental factors modulate oral-health-related quality of life (OHRQoL). The aim of this study was to analyse sociodemographic and behavioural factors affecting the OHRQoL in Spanish adolescents, by using the Child-OIDP (Child-Oral Impacts on Daily Performances) index. A cross-sectional study was conducted in 337 adolescent schoolchildren aged 13-15 years. A questionnaire on sociodemographic, behavioural and oral self-perception factors was administered with the Child-OIDP questionnaire. Descriptive statistics, Kruskal-Wallis and Mann-Whitney U-tests, as well as a regression model were used in the data analysis. The overall mean Child-OIDP index was 3.28±6.55. It was statistically significantly higher in females than in males (p < 0.001). Mothers having a managerial job showed statistical association with worse OHRQoL (p < 0.001). Caries experience and history of dental trauma were not associated with the oral-health-related quality of life (p > 0.05). Halitosis statistically significantly affected the activities of daily living (p < 0.001). Perceived dental problems, dental treatment needs, self-assessment of oral health status and satisfaction with oral health were associated with the impact index (p < 0.05). Mothers who were managers, female sex, presence of halitosis, and perceived dental treatment needs were the most important predictors of the impact index, while dietary habits, oral hygiene, and dental visits did not affect it. Knowledge of these factors will help dental professionals to apply adequate preventive and therapeutic measures.

Examine the Relationship between DMFT Index, Enamel Defects, and Oral Health-Related Quality of Life in Children with Celiac Disease

Background: Celiac disease (CD) is an autoimmune disorder that harms the epithelium and lamina propria of the small intestine in genetically predisposed individuals. Celiac disease negatively affects oral and dental health. Objectives: This research explored the DMFT index and enamel defects (ED), as well as their association with oral health-related quality of life in children with CD. Methods: In this descriptive-analytical cross-sectional study, 50 children with CD (case group) and 50 healthy children (control group) were examined. The World Health Organization criteria were used to determine the DMFT index. Aine's classification was employed to diagnose ED, and the standard CHILD-Oral Impacts on Daily Performances scale was used to assess child oral health-related quality of life (COHRQoL). The Chi-Square test and Mann-Whitney test were utilized for data comparison. P-values &lt; 0.05 were considered statistically significant. Results: The average DMFT was 2.58 ± 2.39 in the case group and 2.08 ± 1.61 in the control group. According to the Mann-Whitney U test, this difference was not statistically significant (P = .223). The frequency of ED in the case group was significantly higher at 52%, compared to 16% in the control group (P &lt; .001). Additionally, there was a significant difference in the frequency of ED between boys and girls in the two groups (P &lt; .001). The COHRQoL score in the case group, with an average of 24.44 ± 19.91, was significantly higher than that in the control group, which had an average of 13.35 ± 13.65 (P = .002). In both the case and control groups, a significant positive relationship was observed between the COHRQoL score in children and the DMFT index (P &lt; .001). There was also a significant relationship between the COHRQoL score in children with ED in both the case and control groups (P = 0.004). Conclusions: According to the results, there was no difference in the DMFT index between the 2 groups. However, as the DMFT index increased in both groups, the COHRQoL score also increased. The number of ED cases was higher in celiac patients, and this had a significant effect on the COHRQoL score. Additionally, the COHRQoL score was higher in celiac patients compared to the control group.

Oral Health-related Quality of Life Assessed by Child: Oral Impacts on Daily Performances Index and Their Association with Dental Caries Prevalence and Gingival Bleeding Status of 12-year-old School Children in Bhubaneswar City.

To assess the association, if any, between oral health-related quality of life (OHRQoL) measured using child oral impact on daily performances (C-OIDP) index and dental caries and gingival bleeding status among 12-year-old school children of Bhubaneswar city. A cross-sectional descriptive study was conducted, and the data were collected using child oral impacts on daily performances index, a closed-ended questionnaire among the 12-year-old school children of Bhubaneswar, Odisha, India, to find out the association between dental caries prevalence among gingival bleeding status. Data were analyzed using descriptive statistics, and Chi-squared tests were used to determine the significant differences in the variable of interest. The study population consists of 1,034 students, out of which 457 (44.2%) are males and 577 (55.8%) are females. A total of 463 (44.8%) children belonged to private schools, and 571 (55.2%) children belonged to government schools. The prevalence of dental caries among males was found to be 49.8% among males and 49.5% among females. A total of 58.8% of the school children presented the impact of oral problems in at least one of the eight daily performances evaluated by C-OIDP. According to the current study, eating was the most negatively impacted of the eight daily performances; it was also evident that dental caries, gingival bleeding, and OHRQoL were associated.

A Dynamic View of the Challenge-Hindrance Stressor Framework: a Meta-Analysis of Daily Diary Studies

Are some daily job stressors good for employees? The challenge-hindrance stressor framework (CHSF) attempts to shed light on this question by categorizing stressors according to their ability to facilitate (challenge stressors) or inhibit (hindrance stressors) growth and achievement. According to the CHSF, challenge stressors should be associated with increased performance, but also with increased strain which subsequently hurts performance. Conversely, hindrance stressors should be associated with reduced performance both directly and indirectly via strain. Prior meta-analytic investigations have focused on more stable job stressors (using cross-sectional or longitudinal primary studies), and found contradicting resulted in support of the CHSF predictions. In the current meta-analysis, we tested the validity of the CHSF using a more dynamic view of stressors, by applying it to short-term, daily experiences of stressors, strains, and performance outcomes. Results from 78 unique samples indicated that at the within-person level, hindrance stressors have both a direct and an indirect (via strain) short-term effect on performance. Challenge stressors have a positive direct effect on performance but a negative indirect effect via strain. Furthermore, we examined two performance indicators separately: task performance and organizational citizenship behaviors (OCB). The results revealed that challenge stressors have a stronger positive association with OCB than with task performance. Hindrance stressors exhibited the opposite pattern, a stronger negative association with task performance than with OCB. The results of this study suggest that all daily stressors result in strain, which negatively relates to performance, though challenge stressors also have some positive effects on daily performance.

Freezing of Gait Is Associated with Daily Activity Limitations among Individuals with Parkinson’s Disease and Mild Cognitive Impairment

This study investigated the relationship between freezing of gait and daily activities among individuals with mild cognitive impairment due to Parkinson’s disease by determining differences in caregiver-reported daily activity performance between individuals with and without freezing of gait. Cross-sectional baseline data from a longitudinal cohort study were used with 24 participants. Caregivers completed the Activities of Daily Living Questionnaire (ADLQ). Using a Mann-Whitney U test, findings indicated that participants with freezing of gait reported overall higher functional impairment levels on the ADLQ (p=.001), including the household, travel, self-care, employment and recreation, and communication subscores, indicating more perceived impairment. Findings show freezing of gait is associated with daily activity limitations in the home and the community among individuals with mild cognitive impairment due to Parkinson’s disease. Clinicians should consider assessing freezing of gait, as early detection can inform the selection of interventions and strategies to minimize its impact on the performance of daily activities.

Differences in anxiety, depression, and oral health-related quality of life among dental anxiety patients with and without reported abuse experience.

This study aimed to explore the differences in anxiety, depression, and oral health-related quality of life between people with dental anxiety who reported abuse experience (n=60) and people with dental anxiety who did not report abuse experience (n=97). Both groups attended a dental service focused on the treatment of dental anxiety intended for people with a history of physiological or psychological trauma, or odontophobia. The participants responded to a questionnaire that included the Hospital Anxiety and Depression Scale (HADS), Oral Impacts on Daily Performance (OIDP), and the Index of Dental Anxiety and Fear (IDAF-4C+ ). The differences between groups were tested for statistical significance using Welch's T-tests, and linear regression was used to adjust for gender. The participants with reported abuse experience expressed greater psychological symptoms of anxiety and poorer oral health-related quality of life. The participants with reported abuse experience also expressed a higher fear of losing control, as well as feeling shame and disgust. This study shows that individuals with dental anxiety and a history of abuse may face more complex challenges than those with dental anxiety and no history of abuse.

Technology-based instrumental activities of daily living in persons with Alzheimer's disease and related disorders.

Instrumental activities of daily living (iADLs) increasingly involve technology (e.g., making payments online, texting). The current study examined the applicability and diagnostic accuracy of technology-based iADLs in those evaluated for Alzheimer's disease and related dementias (ADRD). A total of 264 care partners of persons undergoing comprehensive interdisciplinary evaluations completed the Functional Activities Questionnaire and 11 technology-based iADL items. Technology-based iADLs applied to more than 80% of patients. Average dependence on technology-based items was overall less than for traditional iADLs. The addition of technology-based items to traditional iADL items slightly improved the ability to identify individuals with dementia. When considered separately, technology-based iADL items demonstrated comparable ability to distinguish between diagnostic stages. Technology use is common in older adults with ADRD for a range of daily activities. Accounting for technology use increases the content validity of existing iADL measures for the modern context and yields comparable diagnostic accuracy. Technology use is often integral to daily activity performance for individuals with Alzheimer's disease and related dementias (ADRD).Daily technologies, such as smartphones, were used frequently by those with ADRD.Many individuals were less dependent on technology activities than traditional activities.Adding technology questions slightly increased diagnostic accuracy for detecting dementia.

The cognitive impact of light: illuminating ipRGC circuit mechanisms.

Ever-present in our environments, light entrains circadian rhythms over long timescales, influencing daily activity patterns, health and performance. Increasing evidence indicates that light also acts independently of the circadian system to directly impact physiology and behaviour, including cognition. Exposure to light stimulates brain areas involved in cognition and appears to improve a broad range of cognitive functions. However, the extent of these effects and their mechanisms are unknown. Intrinsically photosensitive retinal ganglion cells (ipRGCs) have emerged as the primary conduit through which light impacts non-image-forming behaviours and are a prime candidate for mediating the direct effects of light on cognition. Here, we review the current state of understanding of these effects in humans and mice, and the tools available to uncover circuit-level and photoreceptor-specific mechanisms. We also address current barriers to progress in this area. Current and future efforts to unravel the circuits through which light influences cognitive functions may inform the tailoring of lighting landscapes to optimize health and cognitive function.

Design and evaluation options of multimedia applications to support the care of people with mild dementia

In order to cognitively and physically activate people with dementia (MMD) in institutional settings, there are numerous touch-based multimedia applications specifically designed for this target group that are actually being used in practice. In contrast, the use of similar applications in domestic settings has been relatively limited. This study is based on 11expert interviews guided by questions and examines design options and requirements for application content as well as requirements for study designs to provide evidence of the effectiveness of touch-based multimedia applications for MMD and their caregiving relatives (PA). There is ahigh degree of consensus regarding the criteria for requirements for touch-based multimedia applications. Acceptance is highly dependent on user competence, usage practices, experiences and incentive structures; however, there are diverse opinions about their structural and content-related design. The quality of life is mentioned as an essential evaluation parameter for multimedia applications. The highly variable individual life circumstances of MMD and their PAs, along with limited access options and alack of suitability of the multimedia applications, may be causal factors for their relatively limited use, especially in domestic settings. Daily performance capabilities and individual disease progression pose special requirements for the scientific evaluation and the demonstration of the effectiveness of touch-based multimedia applications.

Daily uncertainty may overshadow the role of perceived manager effectiveness on daily performance via experienced daily positive affect: Amultilevel study.

In this study, we expand on the existing work on daily performance by focusing on (1) within-person fluctuation in perceived manager effectiveness in relation to daily positive affective experiences and daily performance and (2) between-person fluctuations in uncertainty as a relevant boundary condition of these relationships. Multilevel data from 101 managers (1,010 measurement occasions) were used to test the hypotheses. The results showed that fluctuations in the perception of a manager's effectiveness related positively to daily positive affective experiences, and this relationship was moderated by the team member's uncertainty levels in such a way that perceived uncertainty buffered the positive effect of leadership effectiveness on positive affective experiences. Further, the findings evidenced a positive association between daily positive affective experiences and daily performance. Finally, results showed a significant indirect effect from perceived manager's effectiveness to daily fluctuations in performance via daily fluctuations in positive affective experiences. Perceived manager's effectiveness made employees feel more positive affective experiences, which contributed to their daily performance. However, uncertainty overshadows the influence of a manager's effectiveness on their workers' positive affective experiences. We discuss implications for theory and practice.

The technological advances of recent decades are having a great impact on society, modifying traditional ways of life by transforming social relationships, transactions, and jobs, among others. The physical activity and sport sectors are not immune to the technological transformation of society, and its adaptation is also taking place, resulting in great technological innovations. The implementation of technology in sports is playing an ever-increasing role by advances in modeling and materials, the design of sports equipment, the monitoring and control of physical and physiological performance, and the improvement of the daily performance of athletes, coaches, and referees.

Evaluation of the Impact of Oral Health on the Daily Activities of Users of the National Health System.

the integration of dentistry services in the Unified Health System in Brazil (SUS) is essential in primary care assistance. we aimed to develop a tool for improving demand flowby evaluating the impact of oral health on the daily activities of users of the Family Health Unitusing the Oral Impacts of Daily Performance (OIDP)tool. In Barretos, Brazil, a cross-sectional study was conducted at a Family Health Unit (FHU)including patients over 12 years old. Oral health impact was assessed using the Oral Impacts of Daily Performance (OIDP) tool, and family risk was measured with the Coelho-Savassi scale. 430 participants, including 411 adults and 19 young people, were recruited. Of the adults, 31% had an average OIDP score of 16.61. For young people, 53% reported an impact (average OIDP score: 28.61). Family risk (R1) was prevalent in 57.9% of young people and 53.3% of adults. Among adults, different activities were affected by risk: smiling without embarrassment (risk level 2), enjoying contact with people (risk level 3), and performing one's job or social role (risk level 1). Emotional state (R3) had the lowest OIDP score (p = 0.029). implementation of the OIDP scale in clinical practice enhances healthcare planning and ensures better-quality and equitable services, thus emphasizing comprehensive oral healthcare within the SUS.

The importance of visual acuity screening in dental education amongst undergraduate dental students: a straightforward method

BackgroundVisual acuity plays a pivotal role in a dental professional's daily performance and screening the students' field of vision in their early formative years ensures successful undergraduate programmes.AimsTo compare near and distance visual acuity and stereopsis in first-year and final-year dental students and investigate students' perception of their vision.MethodThis was a cross-sectional study involving 100 KCL first- and final-year dental students that underwent assessment of their vision and completed a self-perception questionnaire. Near visual acuity was assessed using a standardised near vision test chart, distance visual acuity using COMPlog (Clinical Vision Measurement Systems Ltd, London, UK) computerised software and stereopsis using the Frisby stereotest. On the basis of the Mann–Whitney test, no statistical differences were found between the first-year and final-year students’ near and distance visual acuity, nor in stereopsis difference at a significance level of α = 0.05. The null hypothesis was accepted.Results84% of first-year students and 94% in final-year students attained the highest binocular near visual acuity score of 0.50M. Distance visual acuity scores showed a median ETDRS (Early Treatment Diabetic Retinopathy Study) Letters score 94 in the first-year group and 95 in the final-year group. 8% of students were found to have correctable refractive errors in distance visual acuity. The majority of students across both year groups were able to discern 20 s arc of smallest disparity. Final-year students reported worrying about their eyesight significantly more than the first-year students.ConclusionsNo statistically significant differences were found in near and distance visual acuity, and stereopsis, between first-year and final-year dental students. However, 8% of students were identified with undiagnosed, correctable refractive errors. The importance of students' vision in clinical dentistry is highlighted and regular eye examination is recommended.

Feasibility evaluation of a thermoelectrically cooled photovoltaic module at different arrangements and working conditions: A numerical study

The performance of photovoltaic (PV) modules decreases due to heating in real working conditions. To test the feasibility of utilizing thermoelectric cooling (TEC) devices for active thermal management of PV modules, different hybrid PV-TEC systems are modeled. A numerical model is developed by finite volume method with an iterative solution procedure proposed to handle the resulting non-linear system of equations. Two different thermoelectric modules are incorporated in various numbers and spacings. Results show that if an optimum electrical current is supplied to the TEC devices, a marginal positive power gain can be obtained in most cases compared to an uncooled PV. However, the value of the optimum current is a function of TEC arrangement and also ambient conditions. The power gain of 1.17 W is observed for an insolation of 1000 W/m2 with 45 thermoelectric modules at 144 mm spacing. In general, increasing insolation and decreasing wind speed result in higher power gains in the hybrid system. The daily performance of the hybrid system with optimum electrical input improves 0.25 % and 0.1 % for a typical summer and winter day respectively, which is found to be inferior to passive cooling with fins for all investigated arrangements.

A German version of the Oral Impacts of Daily Performances—reliability and validity

ObjectiveThe Oral Impact of Daily Performances (OIDP) is a dental patient–reported outcome measure (dPROM) for the estimation of oral health–related quality of life (OHRQoL) and takes the frequency as well as the severity of problems into account; however, it is not available in German language. The aim of this study was, therefore, to evaluate the reliability and validity of the German version of the OIDP in patients of a private practice.Material and methodsTranslation of the original OIDP version was performed by a forward–backward process. Reliability was evaluated in terms of construct stability (test–retest) for the single items and the sum scores. The responsiveness to change in oral health status was assessed by pre- and post-treatment comparison, in addition. Validity was assessed as convergent validity in comparison with other dPROMs (OHIP-14; GOHAI) and objective dental findings.ResultsA total of 330 patients participated in this study (mean age: 42.0 (18.0)). The OHRQoL of the participants was relatively high (OIDP score 4.3 (SD 14.3), OHIP score 4.8 (SD 5.3), GOHAI score 54.2 (SD 5.4)). A moderate construct stability for the total OIDP-score (ICC 0.686) was found whilst reliability for the single items varied between 0.179 (social contact) to 0.559 (showing teeth). Significant correlations were found for OIDP and OHIP (p < 0.001; r = 0.361) and OIDP and GOHAI (p < 0.001; r = − 0.391) indicating moderate validity with a tendency to even stronger correlations for OIDP-s and OIDP-f (r ≥ 0.500).ConclusionsThe German version of the OIDP demonstrated sufficient reliability and validity. OIDP’s general performance should be interpreted cautiously as the outcome was detected in a specifically healthy population.Clinical relevanceThe OIDP is yet the only dPROM that evaluates both severity as well as frequency which makes validation interesting regarding specific target populations.

Associations between psychological stress, discrimination, and oral health-related quality of life: the buffering effects of social support networks.

Stress and discrimination negatively affect quality of life, but social support may buffer their effects. This study aims: (1) to examine the associations between psychological stress, discrimination, and oral health-related quality of life (OHRQoL); and (2) to assess whether social support, stress and discrimination interact to modify their associations with OHRQoL. We used cross-sectional household-based data from a study including 396 individuals aged 14 years and over from families registered for government social benefits in a city in Southern Brazil. OHRQoL was measured with the Oral Impacts on Daily Performance (OIDP) scale; psychological stress was assessed with the Perceived Stress Scale (PSS); social support was assessed based on the number of close relatives or friends of the participant, and discrimination was assessed with a short version of the Everyday Discrimination Scale. Interactions were estimated using the relative excess of risk due to interaction (RERI). Adjusted effects were calculated with logistic regression. The prevalence of oral impacts among people with higher and lower PSS scores was 81.6% and 65.5%, respectively (p < 0.01). Social support was found to have no interactions with stress levels and discrimination. The association between social discrimination and OHRQoL (OIDP score > 0) was OR = 2.03 (95%CI: 1.23; 3.34) among people with a low level of stress, but was OR = 12.6 (95%CI: 1.31; 120.9) among those with higher levels (p = 0.09, for interaction). Individuals who reported experiencing higher levels of psychological stress and discrimination had worse OHRQoL; a synergistic effect with social support was not clear.
