Effect of silver diamine fluoride on hyperplastic gingivitis in an adult with intellectual disability-A case report.

Spec Care Dentist 2021 Jul 22. Epub 2021 Jul 22.

National Dental Research Institute Singapore, National Dental Centre Singapore, Singapore, Singapore.

Silver diamine fluoride 38% (SDF) may possess therapeutic effects beyond desensitization, caries prevention and arresting. We report the case of a 41-year-old male with intellectual disability. He had generalized gingivitis on a reduced periodontium and presented with enlarged gingiva with mobile teeth, particularly on the upper anterior and upper left. The inflammation could not be fully resolved despite multiple debridement treatments. Due to prevalent demineralization and hypersensitive teeth on the upper left area, SDF was applied. This not only reduced the perceived hypersensitivity, but significantly improved his periodontal condition and tooth mobility over the applied areas. We discuss the potential of SDF beyond its current use.

Oral health status and barriers to care in a multiethnic mixed disability center: Rethinking disability community dental services.

Spec Care Dentist 2020 Jul 5;40(4):344-355. Epub 2020 Jun 5.

Nanyang Polytechnic, Oral Health Therapy, 180 Ang Mo Kio Ave 8, 569830, Singapore.

Aims: There are currently neither onsite services nor any known studies that addresses oral health of persons with special care needs (PSCN) within disability activity centers in Singapore. This study aims to report on the oral health status, disability-related barriers, and assess how these barriers limit care pathways.

Methods And Results: 29 PSCN from a multiethnic mixed disability day activity center were screened over two days. Their ages ranged from 18-59 years old (mean: 31.3). Proportion of Chinese, Malay and Indian ethnicity was 69.6%, 26.7% and 10.3% respectively. 11 were female. Only three PSCN were dentally fit, the average required almost four treatments each. 65.5% had "poor" to "very poor" oral hygiene. The mean number of decayed, missing and filled teeth were 2.8 (95% CI: 1.3-4.1), 1.9 (95% CI: 1.2-3.1), and 1.9 (95% CI: 1.2-3.1), respectively. DMFT had a moderate positive (Pearson's) correlation with age (r = 0.4549, P < .05). The average British Dental Association (BDA) total banded score was 16.97, categorized as "moderate complexity." 51.7% were wheelchair users, while 41.3% needed support. Pharmacological behavioral management had to be considered for 17.2%. The odds ratio was 10 and relative risk 5.26 for requiring additional behavioral modifications and requiring more than average treatment.

Conclusion: This multiethnic cohort of mixed disabilities displayed considerable unmet dental needs and a conflux of barriers to care. Pathways to care and study limitations are discussed.

Special care dentistry in a charity clinic: Demographic analysis and barriers to care in Singapore.

Ci Ji Yi Xue Za Zhi 2019 Oct-Dec;31(4):232-239. Epub 2019 Sep 16.

Dental Services, Tzu Chi Foundation Free Clinic, Singapore.

Objective: Geriatric and special care dentistry (GSD) aims to improve oral health of seniors or adults disabilities facing barriers to care. This is coherent with the philosophy of "compassion relief." Tzu Chi Singapore's Free Clinic exemplifies this through promoting health via various avenues to reach out. This article aims to provide a demographic analysis of patients with special care needs (PSCN), including age, gender, race, medical diagnoses, and treatment rendered. The patients were appraised on their complexity with the British Dental Association case mix model.

Materials And Methods: PSCN seen by a dentist in Tzu Chi Singapore from November 2016 to December 2017 were recorded. The profiling of patients was done retrospectively.

Results: Fifty-five dental PSCN were treated over 82 visits. 58.2% were seen in the free clinic, 27.3% in nursing homes, and 14.5% in oral health day programs for adults with intellectual disability. Their average age was 61.2 years, and the clinic was attended by patients of different races. Their medical profiles were grouped into seven categories, and the average case mix total banded score was 21.6, indicating that the average patient had "severe complexity". A few themes relevant to Singapore were discussed, such as specialist GSD clinics, accessing dental services, socioeconomic status, state versus charity healthcare, and provision of future GSD services.

Conclusions: Charity dental services such as free clinic can capture a niche of complex patients who may become marginalized in an established public healthcare.
