Assessment of Oral Diadochokinesis (DDK) using Praat Software in Removable Complete Denture Patients

Abstract

Introduction: Speech function is known to deteriorate with age and tooth loss. Dentures play a role in restoring and improving speech function of the patient. Assessing speech function with syllable repetition can be done by the Oral Diadochokinesis (DDK) method based on two parameters, Alternating Motion Rate (AMR) and Sequential Motion Rate (SMR). This research aims to determine the description of word repetition based on DDK and assess DDK using Praat software in removable complete denture patients. Methods: Analytic observational research with consecutive sampling technique was conducted on ten patients at the Prosthodontia Polyclinic of RSGM Padjadjaran University. Primary data were collected using the DDK method before and after complete denture insertion by assessing parameters of AMR and SMR. and recorded using praat. AMR were measured by pronounced of monosyllables /pa/, /ta/, and /ka/ in 20 repetitions of each in a breath. SMR were measured by pronounced of trisyllables pataka and batako in 10 repetitions of each in a breath. In addition, each assessment was performed twice and recorded using computer Praat with microphone. As control was two dentate adults with at least 28 teeth and no complaints of speech disorders. Data collected were time, pitch, intensity, and formant based on the fitures of the praat and presented descriptively. Results: The repetition time of DDK with AMR and SMR tended to accelerate after insertion but did not reach a similar assessment with the control. Pitch, intensity, and formant showed variations in increase and decrease after insertion, even surpassing the control in some point. Conclusion: There was an increase in DDK values after denture insertion but did not reach a similar assessment to dentate. Pitch, intensity, and formant varied in increase and decrease after insertion compared to dentate adults.
