Patient Expectation and Satisfaction with Different Prosthetic Treatment Modalities.

PURPOSE: To investigate the relationships between gender, age, patients' perceptions about the dentists' conduct, number of adjustments, treatment type, and expectation prior to prosthetic treatment and patient satisfaction with their treatments.

MATERIALS AND METHODS: Data were integrated from four studies that measured patient expectations before treatment and satisfaction after treatment using a visual analog scale (VAS) from 0 to 10. These scores were given for each of four aspects of the therapeutic outcomes: chewing, esthetics, phonetics, and comfort. Patients' perceptions about the dentists' conduct was also assessed using a Likert-scale questionnaire. The total sample size, after combining the data from all four studies, was 223 subjects. Bivariate and multivariable analyses were performed. The covariates entertained were gender, age, treatment type, patients' perceptions about the dentists' conduct, number of adjustments, and expectation prior to denture fabrication.

RESULTS: In the entire sample, 115 (51.57%) patients were females and 108 (48.43%) were males. They ranged in age from 28 to 81 years old; the mean age was 53.2 years (SD = 11.5). Combining four treatments together, there was no significant difference between patients' expectation and satisfaction scores for all four items. There were no significant differences between expectation and satisfaction for different genders. Multivariable analysis showed that patient expectation, satisfaction and the difference (satisfaction score-expectation score) scores for all four aspects were associated with treatment type (implant treatments were favored), and expectation prior to prosthetic treatment (the higher the expectation, the higher the satisfaction) was associated with satisfaction and difference scores. Satisfaction and difference scores for chewing were associated with number of adjustments and satisfaction, and satisfaction and difference scores for phonetics and comfort were associated with how well the dentist explained the intended treatment before performing it.

CONCLUSIONS: Patient satisfaction was associated with treatment type (implant treatments were favored), expectations prior to prosthetic treatment (the higher the expectation, the higher the satisfaction), and how well the dentist explained the intended treatment before performing it.
