- Abstract
Aims: To analyze differences in salivary pH before eating, and at 5, 30, and 60 minutes after eating before brushing teeth, and after brushing teeth in elderly using removable partial dentures. Materials and methods: This is a quasi-experimental study with a pretest-posttest control group design. The study included a total of 22 participants who were required to eat rice. The participant provided saliva samples before eating, and for 3 consecutive days after eating with different time intervals before and after brushing the teeth. The time intervals were categorized as 5 minutes after eating (T0), 30 minutes after eating (T1), and 60 minutes after eating (T2). On the first day, saliva samples were taken before eating, at T0 before brushing teeth, and after brushing teeth. The exact process was repeated on the 2nd and 3rd days with T1 and T2. Saliva was collected in sterile tubes, stored in a cooler box, and measured with a pH meter. The data were analyzed using the general linear model (GLM) repeated measures analysis of variance (ANOVA) (p < 0.05), one-way ANOVA test (p < 0.05), and independent t-test (p > 0.05). Results: There was a significant difference in the group after eating before brushing their teeth with an average pH of 5.86 ± 0.22 (T0); 6.48 ± 0.12 (T1); and 6.64 ± 0.15 (T2) and after eating after brushing your teeth with an average pH of 7.26 ± 0.07 (T0); 7.30 ± 0.06 (T1); and 7.32 ± 0.04 (T3), respectively. There wasn't any significant difference in the pH between the upper and lower jaw of removable partial dentures in each time group. Conclusion: Salivary pH is typically acidic in the morning. Eating causes a decline in saliva pH, and the elderly have limited saliva buffering capacity to restore pH to neutral. Brushing teeth 5 minutes after eating brings salivary pH back to neutral. There were no significant differences in salivary pH between elderly individuals using upper or lower-jaw removable partial dentures. These findings emphasize the crucial role of timely toothbrushing in preserving oral health among the elderly. Clinical significance: There were significant findings in the acidity of salivary pH in the elderly using removable partial dentures and the correct time to brush their teeth after meals. Understanding this could help prevent carries and determine the right time to brush their teeth.
