PATIENT-REPORTED OUTCOME MEASURES FOR PEDIATRIC DENTAL PATIENTS: A METHODOLOGICAL REVIEW AND MAPPING EXERCISE

Linking patient-reported oral and general health-related quality of life

Background

The relationship between oral and overall health is of interest to health care professionals and patients alike. This study investigated the correlation between oral health-related quality of life (OHRQoL) and health-related quality of life (HRQoL) in a general adult population.

Methods

This cross-sectional study used a convenience sample of adult participants (N = 607) attending the 2022 Minnesota County and State fairs in USA, the 5-item Oral Health Impact Profile (OHIP-5) assessed OHRQoL, and the 10-item PROMIS v.1.2 Global Health Instrument assessed HRQoL. Spearman and Pearson correlations were used to summarize the bivariable relationship between OHRQoL and HRQoL (both physical and mental health dimensions). A structural equation model determined OHRQoL-HRQoL correlations (r). Correlations' magnitude was interpreted according to Cohen's guidelines (r = 0.10, 0.30, and 0.50 to demarcate "small," "medium," and "large" effects, respectively).

Results

OHRQoL and HRQoL correlated with r = 0.52 (95% confidence interval, CI: [0.50-0.55]), indicating that the two constructs shared 27% of their information. According to Cohen, this was a "large" effect. OHRQoL, and the physical and mental HRQoL dimensions correlated with r = 0.55 (95% CI: [0.50-0.59]) and r = 0.43 (95% CI: [0.40-0.46]), respectively, indicating a "large" and a "medium" effect. OHRQoL and HRQoL were substantially correlated in an adult population.

Conclusion

Using OHIP-5 to assess their dental patients' oral health impact allows dental professionals to gain insights into patients' overall health-related wellbeing.

A critical look at outcome measures: Comparison between four dental research journals by use of a hierarchical model

AIM

To assess the status quo of outcome measures used in treatment studies in Endodontics, and potentially identify strategies for improvement, by (i) systematically assessing the outcome measures using a conceptual model and (ii) comparing these with measures used in corresponding studies in the adjacent fields.

METHODOLOGY

The International Endodontic Journal, Caries Research, The Journal of Clinical Periodontology and The Journal of Oral & Facial Pain and Headache were selected to cover four adjacent dental disciplines. In each journal, the 50 most recent consecutive publications fulfilling inclusion criteria were included. A hierarchical model for diagnostic imaging studies was modified to assess studies related to treatment. The model comprised six levels, with technical as the lowest level and societal as the highest. Extracted data included study origin, study type, and identified outcome measures. Fisher's Exact Tests with Bonferroni corrections compared studies. p < .05 was considered statistically significant.

RESULTS

Amongst 756 publications, the 200 most recent studies matching the inclusion criteria were identified. Less than half (36.5%) assessed the clinical, patient, or societal aspects of treatment; 10.0% in International Endodontic Journal, 28.0% in Caries Research, 38.0% in Journal of Clinical Periodontology, and 70.0% in Journal of Oral & Facial Pain and Headache (p < .001).

CONCLUSIONS

According to included publications, research on treatment within the endodontic field is mainly focusing on technical and biological outcomes. The benefits of patients and society were less frequently examined than in corresponding journals in adjacent disciplines. When designing studies, including higher-level outcomes should be considered.

DENTAL PATIENT-REPORTED OUTCOMES UPDATE 2023

The emergence and rapid development of disruptive innovations are quickly turning our profession into personalized dentistry, built upon evidence-based, data-oriented, and patient-centered research. In order to help improve the quality and quantity of patient-centered evidence in dentistry, further promote the wide and standard use of dental patient-reported outcomes (dPROs) and dental patient-reported outcome measures (dPROMs), the Journal of Evidence-Based Dental Practice has put together this special issue, the third of a series entitled Dental Patient-Reported Outcomes Update. A total of 7 solicited articles are collected in this issue. To put them into a broader perspective, this review provides a concise summary of key, selected PRO and dPRO articles published during 2023. A brief introduction to those articles included in this Special Issue follows. Four main domains are covered in this Special Issue: (1) dPROs and digital dentistry, (2) standardization of dPRO-related methodology, (3) current usage of dPROs and dPROMs in published research, and (iv) the significance and relevance of dPRO usage.

OHIP-5 FOR SCHOOL-AGED CHILDREN

BACKGROUND

Different dental patient-reported outcome measures (dPROMs) exist for children and adults, leading to an incompatibility in outcome assessment in these 2 age groups. However, the dental patient-reported outcomes (dPROs) Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact are the same in the 2 groups, providing an opportunity for compatible dPRO assessment if dPROMs were identical. Therefore, we adapted the 5-item Oral Health Impact Profile (OHIP-5), a recommended dPROM for adults, to school-aged children to allow a standardized dPRO assessment in individuals aged 7 years and above.

AIM

It was the aim of this study to develop a 5-item OHIP for school-aged children (OHIP-5School) and to investigate the instrument's score reliability and validity.

METHODS

German-speaking children (N = 95, mean age: 8.6 years +/- 1.3 years, 55% girls) from the Department of Pediatric Dentistry at the Medical University of Vienna, Austria and a private dental practice in Bergisch Gladbach, Germany participated. The original OHIP-5 was modified and adapted for school going children aged 7-13 years and this modified version was termed OHIP-5School. It's score reliability was studied by determining scores' internal consistency and temporal stability by calculating Cronbach's alpha and intraclass correlation coefficients, respectively. Construct validity was assessed comparing OHIP-5School scores with OHIP-5 as well as Child Perceptions Questionnaire (CPQ-G8-10) scores.

RESULTS

Score reliability for the OHIP-5School was "good" (Cronbach's alpha: 0.81) or "excellent" (Intraclass correlation coefficient: 0.92). High correlations between OHIP-5School, OHIP-5, and CPQ-G8-10 scores were observed and hypotheses about a pattern of these correlations were confirmed, providing evidence for score validity.

CONCLUSION

The OHIP-5School and the original OHIP-5 are short and psychometrically sound instruments to measure the oral health related quality of life in school-aged children, providing an opportunity for a standardized oral health impact assessment with the same metric in school-aged children, adolescents, and adults.

Update of the molar incisor hypomineralization: Würzburg concept

PURPOSE

Molar incisor hypomineralization (MIH) is playing an increasingly important role in dental practice. MIH is defined as hypomineralization of systemic origin of one to four permanent first molars, often associated with affected incisors. Affected teeth are more susceptible to caries and post-eruptive enamel loss and should be diagnosed and treated as early as possible. In 2016, the Würzburg concept was developed for German-speaking countries including a classification index-the MIH Treatment Need Index (MIH-TNI)-and a treatment plan based on it for the use in daily practice. In the meantime, the concept has also gained international recognition. The aim of this paper is to update part 2 of the Würzburg concept, the treatment plan, as knowledge about MIH has increased and the disease has been studied more extensively in the last years. Other treatment approaches are now available and therefore need to be included in the concept. Although, the evidence of the different treatment options is still weak, practitioners need guidance in their daily practice.

METHODS

The authors reviewed the available literature, including clinical and laboratory studies and published guidelines.

RESULTS

The updated version of the Würzburg concept includes additional non-invasive strategies and temporary therapy options, as well as treatment approaches for incisors. It therefore covers currently available treatment modalities for MIH-affected teeth, ranging from prophylaxis, non-invasive treatment to restorative approaches and possibly even extraction.

CONCLUSIONS

This is intended to help guide the practitioner and will need to be further validated by clinical trials.

A Bibliometric Mapping Study of the Literature on Oral Health-related Quality of Life

BACKGROUND

Oral health is an indispensable component of overall health, and oral health status significantly influences people's physical, mental, and social well-being. Oral health-related quality of life (OHRQoL), an important and widely used dental patient-reported outcome (dPRO), is attracting more and more researchers' attention and interest. This study aimed to analyze and map the existing scientific literature regarding OHRQoL through a bibliometric approach, including a summary of the characteristics of OHRQoL-related publications, the identification of prolific entities, high-frequency keywords analysis, and research trend analysis via periodic high-impact keywords.

METHODS

A literature search was conducted in the Web of Science Core Collection to collect OHRQoL-related original research and review articles. After examination and deduplication, the following bibliometric information was extracted from each article: title, abstract, keywords, authors, affiliations, geographic origin (countries/regions), year of publication, journal name, and references. Various scientometric mapping tools including Microsoft Office spreadsheet, VOSviewer, Biblioshiny R-package software, and Scimago Graphica were used to analyze basic bibliometric parameters, leading producers, high-impact keywords, and research trends.

RESULTS

A total of 3324 OHRQoL-related articles (3119 original research articles and 205 review papers) were collected, which received 65,704 citations. A total of 9950 authors from 2429 organizations contributed to this body of research. Prolific authors from Europe, USA, Brazil, New Zealand, China, and Canada were identified, and they also centered collaboration clusters in the co-author network. Community Dentistry and Oral Epidemiology was the most prolific journal. Twenty-one keywords with more than 200 occurrences, and 23 keywords with more than 150 occurrences, were identified for publications of 1994-2021 and 2012-2021, respectively. Keyword analysis revealed hot topics such as instrument development and validation, studies targeting children and adolescents, as well as clinical studies in operative dentistry, implantology, orthodontics, and community dentistry. Oral Health Impact Profile is the most commonly used instrument in OHRQoL-related research.

CONCLUSIONS

OHRQoL is an impactful topic in dental health care as it is not only useful in dental research and patient-centered clinical outcome measures but also provides valuable guidance in dental public health administration and policy making. OHRQoL-related research presents a dynamic landscape and is expected to continue presenting high productivity and broad application in the future.

HOW TO IDENTIFY SUBGROUPS IN LONGITUDINAL CLINICAL DATA: TREATMENT RESPONSE PATTERNS IN PATIENTS WITH A SHORTENED DENTAL ARCH

BACKGROUND

When dental patients seek care, treatments are not always successful,that is patients' oral health problems are not always eliminated or substantially reduced. Identifying these patients (treatment non-responders) is essential for clinical decision-making. Group-based trajectory modeling (GBTM) is rarely used in dentistry, but a promising statistical technique to identify non-responders in particular and clinical distinct patient groups in general in longitudinal data sets.

AIM

Using group-based trajectory modeling, this study aimed to demonstrate how to identify oral health-related quality of life (OHRQoL) treatment response patterns by the example of patients with a shortened dental arch (SDA).

METHODS

This paper is a secondary data analysis of a randomized controlled clinical trial. In this trial SDA patients received partial removable dental prostheses replacing missing teeth up to the first molars (N = 79) either or the dental arch ended with the second premolar that was present or replaced by a cantilever fixed dental prosthesis (N = 71). Up to ten follow-up examinations (1-2, 6, 12, 24, 36, 48, 60, 96, 120, and 180 months post-treatment) continued for 15 years. The outcome OHRQoL was assessed with the 49-item Oral Health Impact Profile (OHIP). Exploratory GBTM was performed to identify treatment response patterns.

RESULTS

Two response patterns could be identified - "responders" and "non-responders." Responders' OHRQoL improved substantially and stayed primarily stable over the 15 years. Non-responders' OHRQoL did not improve considerably over time or worsened. While the SDA treatments were not related to the 2 response patterns, higher levels of functional, pain-related, psychological impairment in particular, and severely impaired OHRQoL in general predicted a non-responding OHRQoL pattern after treatment. Supplementary, a 3 pattern approach has been evaluated.

CONCLUSIONS

Clustering patients according to certain longitudinal characteristics after treatment is generally important, but specifically identifying treatment in non-responders is central. With the increasing availability of OHRQoL data in clinical research and regular patient care, GBTM has become a powerful tool to investigate which dental treatment works for which patients.

DENTAL PATIENT-REPORTED OUTCOMES UPDATE 2022

Much progress has been made this year in patient-reported outcomes related research. A number of important articles were published, shedding light on relevant methodological issues as well as future directions. In order to further promote the wide use of dental patient-reported outcomes (dPROs) and dental patient-reported outcome measures (dPROMs) in dental research and dental practice, and to provide novel insights into relevant measurement and analytical methods, the Journal of Evidence-Based Dental Practice has put together this special issue, the second of a series entitled Dental Patient-Reported Outcomes Update. To put Special Issue articles into a broader perspective, this review will provide a concise summary of key, relevant PRO and dPRO articles published during the year of 2022. A brief introduction of those manuscripts collected in this Special Issue follows. Six main domains are covered in this Special Issue: (i) the availability and applicability of dPROs and dPROMs, (ii) the current usage of dPROs and dPROMs in published research, (iii) methodological considerations in dPRO-related research, (iv) the landscape and trends of dPRO-related research, (v) the significance and relevance of dPRO usage, and (vi) dPROs and value-based oral health care.

Does orthodontic treatment need have an impact on oral health-related quality of life?

OBJECTIVES

The aims of this study were to determine the frequency of oral health-related quality of life (OHRQoL) impairment in a national representative sample of 8 to 9 year olds in Germany and to evaluate the impact of orthodontic treatment need.

METHODS

Data were collected in the Sixth German Oral Health Study (Sechste Deutsche Mundgesundheitsstudie, DMS 6) and subjects were sampled using a multistage sampling technique. OHRQoL was measured with a modified version of the 5‑item Oral Health Impact Profile (OHIP-5) which was administered in a computer-assisted personal interview. Children were also examined for malocclusion and orthodontic treatment need.

RESULTS

In all, 1892 children aged 8-9 years were invited to take part. Finally, data of 705 children (48.6% female) could be included in the analysis. The OHIP‑5 mean was 1.3 (±2.0). There was no relevant influence from age and gender on the OHIP‑5 summary scores (r < 0.10), but the summary scores differed when analyzed separately regarding orthodontic treatment need or no orthodontic treatment need (1.5 ± 2.0 vs. 1.2 ± 1.9, p = 0.020). Nevertheless, the level appears to be low.

CONCLUSIONS

Malocclusions with orthodontic treatment need have an influence on OHRQoL.

Understanding the feelings and experiences of patients with periodontal disease: a qualitative meta-synthesis

Background

Patients’ experiences, feelings, and perceptions play key roles in quality of life and dental care quality, but they are poorly understood in periodontal disease. Therefore, this meta-synthesis aimed to gain deep insights into the feelings, experiences, and perceptions of people living with periodontal disease.

Methods

Electronic database searches in PubMed, Cochrane Library, EMBASE, Scopus, Web of Science, PsycINFO, CINAHL, and Open AIRE were conducted up to December 2021 (updated in June 2022). The JBI Critical Appraisal Tool was used for quality assessment. Then reviewers integrated findings from qualitative studies with a thematic synthesis approach.

Results

A total of 567 studies were identified, of which eight involving 131 participants met the inclusion criteria. Studies were conducted between 2008 and 2021within Europe (Sweden and UK), Asia (Korea, Indonesia, and Singapore), and Oceania (New Zealand). Three analytical themes with nine descriptive themes emerged from the qualitative data. The themes were as follows: (1) “pressure (physical, psychosocial, and financial),” (2) “coping and adaptation (avoidance of the status quo, trying to understand it, and taking responsibility for their own),” (3) “reflection and evaluation (exploring the causes, personal control, and calling for better dental care).”

Conclusions

This review provides insights into how patients perceive and cope with periodontal disease. The findings highlighted patient-centered care in PD, and based on the findings, it is possible to provide more precise and efficient interventions for better patient compliance and treatment outcomes.
