Speech and OHRQoL in OD treatment in the maxilla
Satisfaction and quality of life
The scores of satisfaction and OHRQoL, measured using respectively the VAS and Dutch OHIP-14, reported by the patients, is shown in table 3. The mean satisfaction of both overall oral health and speech improved during treatment. The average overall satisfaction increased significantly when comparing the CD with the IOD (p:0.008; z: -2.670) and the CD with 3-year follow-up (p:0.005; z: -2.840). The total OHRQoL improved during treatment and follow-up registered with a decreasing OHIP-14 total score. At the start the mean score was 21.45/56. When the IOD was connected to the bar, the score declined significantly to 8.00/56 (p<0.001; z: -3.617). At the 3-year follow-up, a score of 6.13/56 was reported. Comparing the original denture with the IOD 3 years after connection, resulted in a significant decrease of the OHIP-14 total score (p:0.001; z: -3.240).
The patients’ satisfaction with their speech improved significantly when comparing the CD with palatal coverage and the 3 years in function (p:0.009; z: -2.613). The responses of the patients on the first question of the OHIP-14, questioning the impact of the IOD on speech, reflect the increased satisfaction with their speech. The mean scores of this questions vary from 1.70/4 at baseline to 0.95/4 after IOD connection and 0.81/4 after 3 years.
