Patient-centered assessments: how can they be used in dental clinical trials?

Challenges in conducting clinical research in primary care dentistry

The integration of dentistry into primary health care is crucial for promoting patient well-being. However, clinical studies in dentistry face challenges, including issues with study design, transparency, and relevance to primary care. Clinical trials in dentistry often focus on specific issues with strict eligibility criteria, limiting the generalizability of findings. Randomized clinical trials (RCTs) face challenges in reflecting real-world conditions and using clinically relevant outcomes. The need for more pragmatic approaches and the inclusion of clinically relevant outcomes (CROs) is discussed, such as tooth loss or implant success. Solutions proposed include well-controlled observational studies, optimized data collection tools, and the integration of artificial intelligence (AI) for predictive modelling, computer-aided diagnostics and automated diagnosis. In this position paper advocates for more efficient trials with a focus on patient-centred outcomes, as well as the adoption of pragmatic study designs reflecting real-world conditions. Collaborative research networks, increased funding, enhanced data retrieval, and open science practices are also recommended. Technology, including intraoral scanners and AI, is highlighted for improving efficiency in dental research. AI is seen as a key tool for participant recruitment, predictive modelling, and outcome evaluation. However, ethical considerations and ongoing validation are emphasized to ensure the reliability and trustworthiness of AI-driven solutions in dental research. In conclusion, the efficient conduct of clinical research in primary care dentistry requires a comprehensive approach, including changes in study design, data collection, and analytical methods. The integration of AI is seen as pivotal in achieving these objectives in a meaningful and efficient way.

Association of children's oral health and school environment on academic performance in 12-year-old schoolchildren of Quito, Ecuador

OBJECTIVES

The primary aim of this study was to evaluate if children's oral health and oral health-related quality of life (OHRQoL) were associated with school performance. Moreover, the study aimed to examine whether school environment factors influenced this association.

METHODS

This cross-sectional study was based on a population-based sample of 998 12-year-old schoolchildren from 31 public schools in Quito, Ecuador. Trained and calibrated examiners conducted clinical exams for dental caries, dental trauma and malocclusion. Furthermore, children completed the Spanish version of the Child Perception Questionnaire (CPQ11-14 ), and their parents answered questions about socio-economic status. School coordinators provided information on the physical environment, promotion of health practices and the occurrence of negative episodes in the school. There were three outcomes: grades obtained in Spanish language and mathematics and the number of missed school days. Multilevel linear and Poisson regression models were conducted using a hierarchical approach to include the variables guided by a previously created direct acyclic graph.

RESULTS

Children with dental trauma and higher CPQ11-14 scores showed lower grades and school attendance. Schoolchildren from schools with episodes of vandalism had more school days missed.

CONCLUSION

The school performance of 12-year-old children is affected by dental trauma and by a worse OHRQoL, as well as a negative school environment. Therefore, supportive environments and promoting health measures in schools could overcome this worse academic performance in children with oral health problems.

Influence of two caries detection strategies on the quality of life of preschool children: An analysis of secondary outcomes of a 2-Year randomized clinical trial

OBJECTIVE

This randomized clinical trial aimed to evaluate the influence of two caries diagnosis strategies, and subsequent management, on oral health-related quality of life (OHRQoL) of preschoolers. Additionally, the association of the OHRQoL outcomes with the clinician-centred primary outcome used in the main study was also explored.

MATERIALS AND METHODS

This study refers to the OHRQoL secondary outcomes analyses of the so-called RCT 'CARDEC-1'. Three- to 6-year-old children were randomly allocated in two caries detection strategies in primary molars: visual inspection (VIS) or visual + radiographic (RAD) assessment. Participants were diagnosed and treated according to the allocated group and followed up for 2 years. Caregivers answered the Early Childhood Oral Health Impact Scale (ECOHIS) at baseline and after 2 years. Intention-to-treat analysis was performed. ECOHIS scores at baseline and 2 years later were compared using the Mann-Whitney test. Effect sizes, change scores and the minimally important difference (MID) were also compared between groups. Additional analysis was performed to assess if OHRQoL variables could reflect the primary clinical outcome (number of new operative interventions during the follow-up), observing if these met the Prentice criteria.

RESULTS

Two hundred and five children had the ECOHIS answered in both period times (18.7% attrition rate). There was a decrease in total ECOHIS scores, as well as for different domains for both trial groups, with effect sizes varying from 0.43 to 0.77. Comparisons between groups, however, did not show significant differences. In the additional analysis, the OHRQoL variables met the Prentice criteria and presented the same trends observed with the clinician-centred primary endpoint.

CONCLUSION

Caries detection performed by visual inspection alone or associated with radiographic method does not influence the long-term impact on OHRQoL. Furthermore, OHRQoL variables reflect clinical outcomes in this type of clinical trial.

Psychosocial associated factors of early childhood caries and oral health-related quality of life: structural equation model approach

OBJECTIVE

To identify a structural model for the identification of psychosocial associated factors of early childhood caries (ECC) and oral health-related quality of life (OHRQoL) in preschool children and their families.

METHODS

A population-based cross-sectional study was conducted with 533 preschool children from 4 to 6 years-old public and private preschools, from XXX, XXX. Parents/caregivers self-completed the Brazilian versions of the Early Childhood Oral Health Impact Scale (B-ECOHIS) and Resilience Scale as well as a structured questionnaire addressing socioeconomic status and child's oral health behavior. Two dentists who had undergone training and calibration exercises for ICDAS-epi and pufa index (Kappa≥0.95) performed the examinations for ECC. Stages of ECC were classified as free of visible carious lesion, initial caries, moderate caries, extensive caries without pulp consequences and extensive caries with pulp consequences. Data were analyzed using structural equation modeling, using Mplus version 8.6.

RESULTS

Lower socioeconomic status (b=-0.250; p<0.001) and higher frequency of free sugar consumption (b=0.122; p=0.033) were directly associated with a more severe stage of ECC. Lower parental resilience had an indirect impact on more severe stage of ECC which was mediated by the variable 'frequency of free sugar consumption' (b=-0.089; p=0.048). ECC was associated with lower child's OHRQoL (b=0.587; p<0.001) and lower family's OHRQoL (b=0.506; p<0.001).

CONCLUSION

Structural modeling revealed that the severity of ECC negatively impacted the OHRQoL of preschoolers and their families. The main associated factors of the severity of ECC were lower socioeconomic status, higher frequency of free sugar consumption and lower parental resilience.

CLINICAL SIGNIFICANCE

T The findings indicate that psychosocial and behavior variables can be associated with the severity of ECC, and ECC can be associated with negative impact on wellbeing and ability to perform daily activities of preschoolers and their families.

Self‐reported factors for improving patient's dental care: A pilot study

Objectives

Patient‐centered approach can offer valuable information in improving dental care, but literature is scarce. This study aimed to evaluate self‐reported factors beneficial for attendance in dental care.

Material and Methods

Survey data were collected during the summer of 2020 comprising both structured questionnaires and an open question on factors considered beneficial for dental attendance. Voluntary patients over 15 years of age (n = 196, 98%) agreed to fill the questionnaires, and n = 112 of them (57%) also gave open commentary in an urgent dental care clinic, City of Oulu, Finland, comprising the study population. Dental fear was assessed by Modified Dental Anxiety Scale (MDAS) sum scores (min 5, max 25). All utterances (n = 181) on an open question were evaluated by inductive content analysis to create sub‐ and main categories. Covid‐19 pandemic case counts in Finland were low at the time of the survey, but their effect on seeking dental care was asked. The distribution of patients was evaluated by cross‐tabulation, considering their age, gender, and dental fear status; the significance level was p < .05.

Results

Females dominated slightly the study population (57%). The mean age of the respondents was 44 years. Half (50%) had moderate (MDAS score 10−18), and 10% had severe dental fear (≥19). The open responses could be categorized into four main categories. The largest main category by patient count concerned factors related to personnel (29%), followed by the patient (28%) and treatment (25%) related, and administrative factors (19%). Males chose factors falling into categories of administration and treatment while females chose patient and personnel‐related factors (p = .048). Compared to the rest, fearful persons (MDAS > 9) reported more often factors related to personnel and treatment (p = .03). Of all participants, 17% reported seeking less dental care during the pandemic.

Conclusions

Patients value dental personnel and treatment‐related factors, specifically those with fear.

The implementation of PROMs/PREMs in the assessment of orthodontic treatment outcomes: A questionnaire survey

Objectives:

The aim of this study was to explore the impact of self-perceived treatment outcomes and experiences on psychological aspects, reflecting the importance of patient-reported outcome measures (PROMs) and patient-reported experience measures (PREMs) in orthodontic practice.

Materials and Methods:

A questionnaire was constructed using the PROMs/PREMs concepts. It contained five parts: “Demographic data”, “Self-perceived esthetics”, “Self-perceived functional concern”, “Satisfaction of treatment procedures”, and “Psychological aspect”. The questionnaire was piloted in five experts and 50 orthodontic patients to ensure its quality, using content validity, test-retest reliability, and Cronbach’s alpha. The validated version was provided to patients who had a complete fixed appliance orthodontic treatment. These data were analyzed using descriptive statistics, Mann-Whitney U test, and Spearman correlation. In addition, a multiple linear regression was used to analyze whether there were any influential factors on a psychological aspect. Statistical significance was taken at P < 0.05.

Results:

A total of 271 respondents completed the questionnaire. They tended to have positive perceptions toward the outcomes of orthodontic treatment. There was a significant difference in self-perceived esthetics between the male and female groups. Self-perceived esthetic and functional concerns as well as satisfaction of treatment procedures were found to have significant correlations with the psychological aspect. Sex and self-perceived esthetics were also found to be significant predictors of the psychological aspect.

Conclusion:

PROMs/PREMs should be considered as an important tool to assess treatment outcomes in orthodontic practice. There appeared to be significant impact of self-perceived esthetics on psychological aspects. Consequently, PROMs and PREMs should be introduced in orthodontic postgraduate programs to enhance the concept of patient-centered care in orthodontic practice.

Validation of the Brazilian Version of the RMS Tactile Scale (B-RMS-TS)

This study aimed to validate the Brazilian version of the RMS Tactile Scale (B-RMS-TS) in children and adolescents with visual impairment. Ten visually impaired children and adolescents between 10 and 17 years old of an Educational Center for Visually Impaired People answered the verbalized Dental Anxiety Scale (DAS), and the DAS in Braille to evaluate their dental anxiety levels. B-RMS-TS construct validity was assessed by convergent and discriminant validity. Convergent validity was tested in two ways: Pearson's correlation between the B-RMS-TS and the overall anxiety question; Pearson's correlation between B-RMS-TS and verbalized DAS and DAS in Braille. B-RMS-TS reliability was measured by internal consistency (Cronbach's alfa and McDonald's omega) and test-retest reliability (ICC). B-RMS-TS was moderately correlated to the overall anxiety question (r=0.493;p=0.147). B-RMS-TS showed excellent correlation with verbalized DAS (r=0.971;p<0.001) and DAS in Braille (r=0.934;p<0.011). B-RMS-TS was able to discriminate dental anxiety levels between male and female (p=0.008). The B-RMS-TS demonstrated excellent reliability (Cronbach's alpha=0.661, McDonald's omega=0.700 and ICC=0.987; 95%CI=0.817-0.999). B-RMS-TS is valid and reliable to measure dental anxiety levels in Brazilian children and adolescents with visual impairment.

Impact of traumatic dental injury treatment on the Oral Health-Related Quality of Life of children, adolescents, and their family: Systematic review and meta-analysis

BACKGROUND/AIM

Measures of oral health-related quality of life (OHRQoL) are useful in clinical trials to evaluate treatment outcomes. To detect the treatment impact of traumatic dental injuries (TDI) on OHRQoL is extremely relevant. The aim of this study was to assess whether there is scientific evidence of the impact of TDI treatment on OHRQoL of children, adolescents, and their families.

MATERIAL AND METHODS

A systematic review and meta-analysis were conducted selecting articles from PubMed, Web of Science, Scopus, Cochrane Library, and Virtual Health Library until May 22nd, 2020. The gray literature, clinical trial registers, and a manual search were performed. Two independent reviewers selected the studies, extracted the data, and assessed the ROBINS-I risk of bias. A meta-analysis was performed using RevMan 5.4 program. The certainty of the evidence was evaluated using the GRADE system.

RESULTS

In the electronic search, 413 abstracts and one registered study were found. After removing the duplicates and eligibility application, six studies were included. Individually, the studies presented low to moderate risk of bias and they found that TDI treatment reduces the negative impact on OHRQoL. In the meta-analysis, TDI treatment improved OHRQoL for 8- to 10-year-old children (p = .03; CI 5.19 [0.62, 9.75]) (detected by CPQ 8-10 questionnaire). In the perception of parents, the children, and adolescents who had suffered TDI also had their OHRQoL improved (p = .04; CI 14.77 [0.95, 28.60]) (detected by PPQ and P-CPQ questionnaire) but both evaluations had very low certainty of evidence.

CONCLUSION

Treatment of traumatic dental injuries reduces the impact on the OHRQoL of children and adolescents. However, more studies are necessary to detect the TDI treatment influence on OHRQoL of preschoolers and in the family as well to estimate the effects due to outcomes that had a very low certainty of evidence (#CRD42018091210).

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

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