Voice Quality Changes With IANB Anesthesia

Study Overview
=================
Brief Summary
-----------------
Background: Inferior alveolar nerve block anesthesia is commonly used in dental procedures, but its effect on the voice quality is not well understood. The aim of this study is to investigate the effect of mandibular anesthesia on the acoustic voice quality index. Objective: The primary objective of this study is to determine the effect of mandibular anesthesia on the acoustic voice quality index. Design: This is a within-subject study design. Participants will be recruited from a local dental clinic and will be adults aged 18 years or older. The participants will have the acoustic voice quality index measured before and after the administration of mandibular anesthesia. The parameters that will be measured include acoustic voice quality index and self ........ The data will be analyzed using appropriate statistical techniques. Expected Outcome: The study is expected to provide insights into the effect of mandibular anesthesia on the acoustic voice quality index. The results of this study may help in understanding the impact of mandibular anesthesia on voice quality and may have implications for dental practitioners and patients who receive mandibular anesthesia.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Inferior alveolar nerve block anesthesia cohort<br>This group will consist of participants who are undergoing procedures that require mandibular anesthesia as routine part of care. Participants in this group will have voice recordings taken before and after the administration of anesthesia. The aim is to assess any changes in voice characteristics attributable to the effect of the anesthesia. | |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Acoustic Voice Analyze measurements; Motor Speech Profile (MSP) | Motor Speech Profile (MSP), is being used for accuracy and straightness of motor performance of speech. An inaccurate, inconsistent or abnormal oral-diadochokinetic performance may indicate disturbances in central nervous system or peripheral sensory motor functions. The software based on different protocols that provide different motor speech patterns such as oral diadochokinetic (DDK) rate, second formant transition rate, and syllable rate. | Immediate before inferior alveolar nerve block anesthesia, immediately after inferior alveolar nerve block anesthesia roughly 5 minutes later | 
| Change in Acoustic Voice Analyze measurements; Multi-dimensional voice program (MDVP) | Multi-dimensional voice program (MDVP), basically, it is a computer program which analyzes various aspects of voice. It can provide many of acoustic parameters from a voice sample. It is based on a continuous vowel: /a/. | Immediate before inferior alveolar nerve block anesthesia, immediately after inferior alveolar nerve block anesthesia roughly 5 minutes later | 
| Change in Acoustic Voice Analyze measurements; Analysis of dysphonia in speech and voice (ADSV) | Analysis of dysphonia in speech and voice (ADSV), evaluates frequency domain parameters. It is based on 2 different vowels ((/a/ and /i/) from Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) and 6 different sentences. Every single sentence provides different voice analyses such as, containing all the vowels, making sounds with or without glottal attack, nasal sounds or explosive sounds. | Immediate before inferior alveolar nerve block anesthesia, immediately after inferior alveolar nerve block anesthesia roughly 5 minutes later | 
| Change in Acoustic Voice Analyze measurements;Acoustic Voice Quality Index (AVQI) | Acoustic Voice Quality Index (AVQI), measures the perceived quality of a voice signal. It is based on evaluating several acoustic parameters that are known to be related to the perceived quality of speech. These parameters include measures of loudness, pitch and spectral tilt as well as measures of the presence of noise and other distortions in the signal. | Immediate before inferior alveolar nerve block anesthesia, immediately after inferior alveolar nerve block anesthesia roughly 5 minutes later | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in BORG Scale (CR-10) | A method for rating perceived effort and the CR-10 is a semi-public/semi-public tool for different boundaries and different measured structures. It is required for participants to correctly score the perceived effort against the variable during the experimental procedure. An exercise can be planned for setting the extreme points of the experience. | Exercise timing is immediate before inferior alveolar nerve block anesthesia, holding a dental mirror with only lips and tongue, for 2 minutes |
