Oral Health Status and Salivary Parameters in Stroke Patients at a Tertiary Hospital

ABSTRACT

@#Introduction: Dental caries and impaired salivary function are very common but undertreated. The aim of this study was to investigate the oral health status and salivary parameters of stroke patients. Methods: A cross-sectional study was carried out on 54 stroke and 54 non-stroke patients attending rehabilitation treatment at Hospital Universiti Sains Malaysia. Decay, Missing and Filled Teeth (DMFT) index and plaque scores were used to evaluate patients’ oral health. Salivary parameters such as salivary cortisol, salivary flow rate, pH and buffering capacity were measured. Salivary cortisol was analysed using Cobas E6000 automated immunoassay. Results: Among the 54 stroke patients, the majority were Malays 72.2% and 63.0% were male, with a mean age of 48.1 (14) years. There was a significant difference of dental caries between stroke patients, at 17.6 (4.26), compared to 15.7 (5.38) for non-stroke patients (p=0.042). Only 53.7% of stroke patients had good oral hygiene, compared to, 85.2% among non-stroke patients’ (p-value= 0.001). Salivary parameters showed no significant differences (p>0.05). However salivary cortisol levels were higher in stroke patients 5.2(5.1) nmol/L) than in non-stroke patients 4.0 (3.6) nmol/L). There was no significant correlation between salivary parameters and DMFT index (P>0.05). Conclusion: Stroke patients had more dental caries and poor oral hygiene compared to non-stroke patients. Salivary parameters showed no significant difference between stroke and non-stroke patients.
