Objective: Visual impairment may impact on oral health through physical, social or information barriers related to the impairment, attendant medical conditions or lack of information in a suitable format. Oral disease can greatly affect their quality of life and would in turn worsen their capacity to access oral health care especially in subjects with low salivary flow rate. This study was to analyze the association of hyposalivation with oral health status, oral function and nutritional status in visual impaired patient.
Methods: The subjects were 73 visual impaired elderly (mean age, 64.3±3.4 years). Oral function (tasting, speaking, swallowing and chewing) and Mini Nutritional Assessment (MNA) were evaluated. Oral examination investigated teeth and periodontal status. Both unstimulated and stimulated whole saliva were collected for 5 minutes.
Results: Among all subjects, 43.8% were classified within the hyposalivation. Subjects within the hyposalivation group had a higher number of decayed teeth and higher prevalence of periodontitis than the normal salivation group (p＜0.05). The hyposalivation group had a lower mean MNA score then the normal salivation group (p＜0.05). Statistical analysis showed that hyposalivation was significantly associated with chewing and swallowing problems.
Conclusion: This study suggested that hyposalivation is a risk factor not only for dental caries and periodontal disease but also for oral function and malnutrition. Monitoring salivary flow is an important measure in the care of visual impaired patient.
