Older patients' perception of treating root caries with silver diamine fluoride - a qualitative study based on the Theoretical Domains Framework

The Older Adults' Intention to Use Silver Diamine Fluoride for Dental Caries Treatment

Purpose

This study aimed to determine the intention of older adults to use silver diamine fluoride (SDF) for treating tooth decay.

Patients and Methods

A group of Thai-speaking individuals between the ages of 60 and 90 were asked to participate in the study. They were provided with information about SDF and then asked to complete a questionnaire based on the Theory of Reason Action (TRA). The questionnaire consisted of 23 questions divided into seven constructs aimed at determining the determinants of the intention to use SDF. These constructs were behavioral belief, evaluation of behavioral outcome, normative belief, motivation to comply, attitude towards behavior, subjective norm, and intention. The responses were rated on a 4-point Likert scale ranging from 1 (Strongly disagree) to 4 (Strongly agree). The characteristics and TRA scores of the participants were analyzed and compared based on their intention to use SDF, using the Chi-square test and t-test. Multiple logistic regression was employed to determine the determinants of the intention to use SDF.

Results

The study involved 588 participants, with an average age of 65.3 years (SD= 5.53). Of the participants, 52.7% were women, 58.1% were unemployed or retired, 80.8% lived with family, 63.4% had less than sixth-grade education, 62.9% had a monthly family income of less than 10,000 baht, and 63.6% had underlying diseases. The study found that 82.7% of the participants intended to use SDF for dental caries treatment, with an average score of 2.86 out of 4. The study also found that age, family income, underlying diseases, dental health problems, and fear of the dentist significantly affected their intention. Behavioral beliefs and evaluations of behavioral outcomes significantly affected the intention to use SDF treatment.

Conclusion

Most older adults in the study intended to use SDF for dental caries treatment.

Acceptance of silver diamine fluoride use in community dwelling older adults, nursing home residents, and caregivers

OBJECTIVES

To compare the level of acceptance of silver diamine fluoride (SDF) treatment between different functional groups of older adults aged 65-years-old and above.

METHODS

Three groups were recruited representing functionally-independent ("Community dwelling"), frail ("Nursing home"), and functionally-dependent older adults ("Caregiver": proxy respondent involved in caring for an older adult of all functional levels). Participants viewed a video on SDF and an interviewer-led questionnaire collected demographics, dental experience and perception on SDF use.

RESULTS

The study recruited 201 participants (100 "Community dwelling", 51 "Nursing home", 50 "Caregiver"). Overall, 73 % of participants were accepting of SDF treatment. Those in the "Community dwelling" group were most accepting (85 %), followed by the "Nursing home" group (61 %) and "Caregiver" group (60 %) (p<0.001). Participants were more accepting of SDF use on posterior (73 %) compared to anterior teeth (46 %). They were more accepting when SDF was presented as a treatment to avoid infection and pain (87 %), and general anesthesia (78 %). In a regression analysis, "Nursing home" and "Caregiver" participants were three times less likely to accept SDF (OR 0.27 [95 % CI: 0.13 to 0.60], and OR 0.27 [95 % CI: 0.12 to 0.58] respectively) compared to "Community dwelling" participants. After adjusting for other factors, only the "Caregiver" group remained significant (Adjusted OR 0.32 [95 % CI: 0.13 to 0.78]).

CONCLUSIONS

Older adults were accepting of SDF and this treatment modality has the potential to be a routine treatment option in dental caries management in this population. However, this was less certain among frail and functionally dependent older adults.

CLINICAL SIGNIFICANCE

An SDF program to manage caries is likely to be well-received by functionally-independent older adults. However, the acceptance among frail and functionally-dependent older adults were lower even though SDF is mostly likely to benefit these populations. There is a need to investigate this relatively lower levels of acceptance.

Evaluation and management of dry mouth and its complications in rheumatology practice

INTRODUCTION

The symptom of dry mouth has multiple potential etiologies and can be a diagnostic clue to the presence of common systemic diseases encountered in rheumatology practice. The presence of decreased saliva flow (i.e. salivary hypofunction) defines a subset of dry mouth patients in whom there may be reversible drug effects, an iatrogenic insult such as head and neck irradiation, or a disease that directly involves the salivary glands (e.g. Sjögren's disease). The assessment of salivary hypofunction includes sialometry, salivary gland imaging, salivary gland biopsy, and an assessment for relevant systemic diseases. Optimal management of dry mouth requires accurate definition of its cause, followed by general measures that serve to alleviate its symptoms and prevent its complications.

AREAS COVERED

Through a literature search on xerostomia and salivary hypofunction, we provide an overview of the causes of dry mouth, highlight the potential impact of salivary hypofunction on oral and systemic health, detail routine evaluation methods and treatment strategies, and emphasize the importance of collaboration with oral health care providers.

EXPERT OPINION

Our Expert Opinion is provided on unmet needs in the management of dry mouth and relevant research progress in the field.
