Impact of Anterior Cross Bite Treatment on Children's Speech Performance

Study Overview
=================
Brief Summary
-----------------
The goal of this prospective, single-arm clinical trial is to evaluate the speech performance of children with anterior dental crossbite before and after correction. Also, to assess the impact of early interceptive orthodontic treatment in the mixed dentition stage to correct the anterior dental crossbite on the quality of life of children. Fifty children of both sexes aged from 8 to 10 years were enrolled and evaluated using the study's inclusion & exclusion criteria. before beginning interceptive orthodontic treatment, each child underwent full mouth treatment. then, using a removable anterior expansion screw along with posterior bite planes to treat the anterior crossbite. All children were subjected to the Protocol of speech evaluation before appliance insertion and after complete correction of anterior crossbite. Also, the Child Perceptions Questionnaire (CPQ 8-10) in the Brazilian version was used to gauge how the anterior crossbite affected the children's oral health-related quality of life.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: anterior crossbite treatment with evaluation of speech and quality of life<br>removable anterior expansion screw is used to correct anterior crossbite Child Perceptions Questionnaire was used to gauge how the anterior crossbite affected the children's OHRQoL. children were subjected to the Protocol of speech evaluation | Device: removable anterior expansion screw<br>* For the upper and lower arches, precise and profound alginate impressions were obtained and plaster study models were created. The removable appliance was constructed using acrylic resin with bilateral occlusal coverage for posterior teeth. The removable appliance was inserted in the patient's mouth and the patient was recalled after 24 hours to check the appliance fit. Patient was recalled every four weeks until the dental cross-bite was corrected.<br>Diagnostic Test: Speech and language evaluation<br>* speech evaluation was done by a Phoniatrician and all children were subjected to the Protocol of speech evaluation before expansion screw appliance insertion and after complete correction of anterior crossbite using an articulation test, intelligibility test, and spectrographic analysis. Articulation test: Five speech sounds were chosen to be studied /s/, /s /, /z/, /z/, /∫ /. The consonants were tested in the initial, medial, and final word positions. Speech intelligibility test : The general intelligibility score was calculated using Speech intelligibility in context: 5 -point scale: Spectrographic analysis: Using the computerized speech lab, the child was seated in an upright position & allowed to talk freely & repeated syllables were said to him/her.<br>Other: Oral Health Related Quality of Life (OHRQoL) Assessment<br>* The Child Perceptions Questionnaire (CPQ 8-10) in Brazilian version was used to gauge how the anterior cross bite affected the children's OHRQoL. It has twenty-five items total, broken down into four health domains (subscales): five questions each about oral symptoms (OS), five questions about functional limitations (FL), five questions about emotional wellbeing (EW), and ten questions about social well-being (SW). The responses never (0), once/twice (1), occasionally (2), often (3), and every day/almost every day (4) are provided for each question on an ordinal scale. The sum of the scores for all questions is used to calculate the scores for each subscale. The CPQ 8-10 was used to assess the OHRQoL before appliance insertion and after complete correction of anterior crossbite.<br>|

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| normal anterior occlusion, no anterior crossbite, normal measured Overjet and Overbite | Normal occlusion is measured as: no anterior crossbite Overbite 1 mm to 4 mm Overjet 1mm to 4 mm | 3 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| child compliance, oral health-related quality of life questionnaire | The earlier tested questionnaire is used to compare child compliance before and after anterior crossbite correction | 3 months | 
| Measured degree of speech improvement | The pre-treatment assessed speech sounds are compared with the post-treatment assessment | 3 months |
