Effect of Age on Flow-Rate, Protein and Electrolyte Composition of Stimulated Whole Saliva in Healthy, Non-Smoking Women

As relatively little is known about the effect of age on salivary electrolytes we studied the composition of saliva as function of age to provide reference values for healthy non-smoking women. All non-medicated and non-smoking 30-59-year-old subjects (n=255) selected from among 1030 women participating in a screening program formed the material of the present study. Salivary calcium, inorganic phosphate, magnesium, sodium, potassium, protein and flow-rate of stimulated whole saliva were measured. We found age-related changes in salivary calcium and phosphate concentrations (p=0.001 and p=0.004, respectively, one-way ANOVA). Peak values occurred at around 50-54 years of age. Age had no effect on flow-rate, magnesium, sodium, potassium or proteins. The concentration of sodium correlated positively, while phosphate, potassium, magnesium and protein correlated negatively with the salivary flow-rate. Calcium was the only electrolyte which had no association with flow-rate. Our study provides reference values for salivary electrolytes of 30-59-year-old women

The Impact of Oral Health on Taste Ability in Acutely Hospitalized Elderly

Objective: To investigate to what extent various oral health variables are associated with taste ability in acutely hospitalized elderly. Background: Impaired taste may contribute to weight loss in elderly. Many frail elderly have poor oral health characterized by caries, poor oral hygiene, and dry mouth. However, the possible influence of such factors on taste ability in acutely hospitalized elderly has not been investigated. Materials and Methods: The study was cross-sectional. A total of 174 (55 men) acutely hospitalized elderly, coming from their own homes and with adequate cognitive function, were included. Dental status, decayed teeth, oral bacteria, oral hygiene, dry mouth and tongue changes were recorded. Growth of oral bacteria was assessed with CRTH Bacteria Kit. Taste ability was evaluated with 16 taste strips impregnated with sweet, sour, salty and bitter taste solutions in 4 concentrations each. Correct identification was given score 1, and maximum total taste score was 16. Results: Mean age was 84 yrs. (range 70–103 yrs.). Total taste score was significantly and markedly reduced in patients with decayed teeth, poor oral hygiene, high growth of oral bacteria and dry mouth. Sweet and salty taste were particularly impaired in patients with dry mouth. Sour taste was impaired in patients with high growth of oral bacteria. Conclusion: This study shows that taste ability was reduced in acutely hospitalized elderly with caries activity, high growt

The effect of an oral health education program after three years

Three years after providing an oral health education program (OHEP) to nursing personnel, the authors analyzed the effect of the program on knowledge of the importance of oral health and on perception among the nurses of the possibility to implement oral care in patient care. The study was based on a cross-sectional survey of all nursing personnel (N = 2,901) in five municipalities in the Southwestern Sweden, of whom 950 had attended four one-hour lessons during an OHEP in 1996. The response rate to the survey questionnaire was 67% (1,930 subjects). Statistical analysis was performed by means of descriptive and analytical statistics. The program was shown to have an independent effect on the dependent variables "knowledge of oral health "and" assessment of implementation possibilities," This study has given further evidence of the feasibility of an educational program to improve both knowledge and implementation of oral health care
