Ultra-short version of the oral health impact profile in elderly Chileans

Structural validity and reliability of the "Oral Health Assessment Tool" applied by speech-language therapists in a population of older Chilean people

BACKGROUND

A good state of oral health allows people to communicate and eat. This topic is relevant in older people given its close relationship with their general health. At present, health challenges are directed at detecting and preventing oral disorders and are seen to exclusively by dentists, because the existing instruments can only be applied by them. However, speech-language therapists undergo similar training, which would allow them to collaborate in these processes. In this context, the Oral Health Assessment Tool (OHAT) is a detection instrument with good psychometric properties that is currently available for non-dental use. The objective of this study is the translation into Chilean Spanish of the OHAT and a structural validation of that version for application by these professionals.

MATERIALS AND METHODS

A mixed qualitative-quantitative study was carried out. The OHAT instrument was adapted to Chilean Spanish and subsequently subject to structural validity and evaluation of internal consistency reliability, as well as a valuation of its reproducibility in 286 older people (166 female, 120 male) from different health contexts.

RESULTS

The cultural adaptation of the instrument proved to be semantically consistent with the original instrument. Its application was considered to be speedy and simple in the pre-test. The confirmatory factor analysis evidenced the unidimensionality of the OHAT. In addition, the instrument shows good internal consistency and test-retest reliability.

CONCLUSIONS

The OHAT instrument was considered to possess adequate structural validity and test-retest reliability properties. Its usefulness in the context of oral health disorders of this population in Chile is discussed.

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.

A 5-Year Retrospective Study Evaluating Periodontal Health and Oral Health-Related Quality of Life of Implant-Supported Overdentures With Locator and Magnetic Attachments

This study compared peri-implant vertical bone loss, the periodontal index, prosthodontic maintenance requirements and oral health-related quality of life (OHQoL) of patients using mandibular implant-supported overdentures with 2 different attachment systems after an average of 5 years of use. Sixteen mandibular overdenture patients with magnet attachments (group 3), 24 with implant-supported mandibular overdentures with Locator attachments (group 2), and 25 conventional complete denture patients (group 1) were included in the study. The existing at least 5 years old dentures of all patients were evaluated for prosthodontic maintenance by the same prosthodontist and the patients were administered the oral health impact profile-14-Turkish version (OHIP-TR-14) questionnaire. Peri-implant tissue health was evaluated clinically in terms of plaque scores, bleeding scores, probing depth, and gingival index. Radiographic evaluation was performed in terms of peri-implant vertical bone loss. Radiographic evaluations were performed 5 years after overdenture insertion. There were no statistically significant differences between the groups in terms of total OHIP-TR-14 scores (P > .05). Although the average vertical bone resorption measured in group 2 at the end of 5 years was 1.38 mm, there was an average vertical bone loss of 1.45 mm in group 3, but this difference was not statistically significant (P > .05). Among the periodontal health indicators, there were no statistically significant differences in the mean values for periodontal indexes. According to results of the study, there were no differences in peri-implant vertical bone loss in groups 2 and 3, in periodontal health in mandibular overdentures with groups 2 and 3, or between total OHIP-TR-14 scores of patients in all groups.

The Spanish Language 5-Item Oral Health Impact Profile

OBJECTIVE

To test validity and reliability of the Spanish version of the 5-item Oral Health Impact Profile (OHIP-Sp5).

METHODS

Spanish-speaking dental patients (n = 331, response rate = 61%, age: 42.9 + 12.3 years, 59% female) with a scheduled appointment at HealthPartners dental clinics in Minnesota, USA, were investigated. To assess score reliability, we computed Cronbach's alpha, expecting 'good' reliability (alpha > 0.70). To assess score validity, we correlated the OHIP-Sp5 summary score with five OHRQoL measures [49- and 14-item OHIP-Sp, the Spanish version of the General Oral Health Assessment Index (GOHAI-Sp), the Spanish version of the Oral Impacts on Daily Performances (OIDP-Sp) and a Global Oral Health Assessment]. We expected a pattern of 'very large' (r > 0.70) correlation coefficients for OHIP-Sp5 relationships with the two longer OHIP-Sp versions and 'large' (r > 0.50) correlation coefficients for the other three measures.

RESULTS

Patients had a mean OHIP-Sp5 score of 3.7 (SD = 4.0). The Instrument's reliability was, as expected, 'good', according to the Cronbach's alpha statistic of 0.83. The Instrument's validity was supported by the expected pattern of validity coefficients. OHIP-Sp5 summary scores correlated with OHIP-Sp14 as well as with OHIP-Sp49 (both r = 0.95: 'very large' effect) and with GOHAI-Sp, OIDP and the Global Oral Health Assessment with r = -0.80, 0.73, and -0.56 (absolute effect magnitude all 'very large' or 'large'), respectively.

CONCLUSIONS

The Spanish version of OHIP-5 is a brief and psychometrically sound instrument to measure oral health-related quality of life (OHRQoL) in Spanish-speaking populations. It can effectively replace longer OHIP instruments and would be applicable across all settings of clinical practice and research.
