| dc.description | During orthodontic retention phase, majority of patients complain of difficulty in pronouncing certain consonance such as ‘t’ ‘d’ ‘k’ ‘n’ and ‘s’. Consequently, patients not wearing the retainer as instructed will lead to relapse or retreatment. Retreatment will add to treatment cost, time and manpower. The purpose of this study is to prospectively evaluate the speech distortion among patient wearing Hawley retainer through acoustic approach by using PRAAT Software. Sixteen orthodontic patients (aged 15 to 31 years) who were in debonding phase were included in this study. The spectrogram analysis was carried out to determine the duration value of selected phonemes based on the recording of patients with and without the wearing of appliances. The analysis were performed before (T0), within 24h (T1), after 1 week (T2), after 2 week (T3), after 1 month (T4), after 2 month (T5) and after 3 month (T6) of wearing the retainer. A subjective evaluation by the patients was done using standardized questionnaire and was completed by patients at three points (after 1 week, 1 month and 3 months) of wearing the retainer. Statistical analysis was done using one-way repeated measures ANOVA and paired samples t test for the experimental part and Friedman two way ANOVA and Wilcoxon Signed rank test for the questionnaire part. The results showed significant (p<0.05) speech distortion was recorded with /t/, /d/, /k/ and /n/ consonant sounds. All those sounds were significantly distorted during the first 24 hours of wearing retainer (p<0.008). Patients also reported the alphabet starting on a word /s/ as the most difficult to pronounce during early part of wearing retainer. Speech distortion reduces as the duration of wearing retainer increases. The findings would be helpful for the clinician to understand and educate patient during orthodontic retention phase hence, improve the patient’s compliance.,Doktor Pergigian Klinikal Ortodontik | - |
