简要总结

This study will assess and compare the levels of pain, discomfort, and functional impairments between rapid and slow maxillary expansion in treating skeletal maxillary constriction in the early adolescence period (i.e. between 12 and 16 years).

The study sample will consist of 32 patients who suffer from a skeletal posterior crossbite. The sample will be allocated randomly into two groups: RME group and SME group.

The patients will be asked to fill out the attached questionnaires at three assessment times.

详细描述

Skeletal maxillary constriction is a popular orthodontic malocclusion that can be seen at any age. The maxillary expansion is the most important treatment choice of this skeletal problem in the upper jaw. There are many types of maxillary expansion regarding the force amount and the number of expansion times: slow maxillary expansion (SME) rapid maxillary expansion (RME), and semi-rapid maxillary expansion (SRME).

Practitioners are conscious that complaints submitted by children and adolescents during the active phase of expansion, such as pain, discomfort and oral ulcers are common symptoms. This trial of two parallel groups will compare the pain, discomfort and functional impairments accompanying the rapid and slow maxillary expansion in early adolescent patients.

RME group: A bonded modified Hyrax palatal expander will be applied. SME group: A removable palatal expansion appliance with a midline screw will be applied.

To assess the pain, discomfort and functional impairments, patients will be asked to fill out questionnaires of six questions: 1) What is the degree of pain/discomfort you have experienced?; 2) Do you have difficulty in mastication?; 3) Do you have difficulty in swallowing?; 4) Do you have a sense of tension or pressure in soft tissue?; 5) Do you have swelling in soft tissue?; and 6) How easy is the treatment procedure?.

结局指标

主要结局

Change in the difficulty in mastication

时间窗: T1: on the 1st day; T2: on the 7th day in the RME group and in the 3rd or 4th month in the SME group; T3: on the 15th day in the RME group and between the 6th and 8th month in the SME group

Patients will be asked this question about any difficulty in mastication (Item no 02): 'Do you have difficulty in mastication?' A standardized questionnaire will assess pain, discomfort and functional impairments' levels during the active phase of treatment. The 4-point Likert scale will be used consisting of: (no), (mild), (moderate) or (severe). The patient will be asked to choose one of the four options.

Change in the sensation of tension or pressure on soft tissue

时间窗: T1: on the 1st day; T2: on the 7th day in the RME group and in the 3rd or 4th month in the SME group; T3: on the 15th day in the RME group and between the 6th and 8th month in the SME group

Patients will be asked this question about any sense of tension or pressure on soft tissue (Item no 04): 'Do you have a sense of tension or pressure in soft tissue ' A standardized questionnaire will assess pain, discomfort and functional impairments' levels during the active phase of treatment. The 4-point Likert scale will be used consisting of: (no), (mild), (moderate) or (severe). The patient will be asked to choose one of the four options.

Change in the degree of swelling in soft tissues

时间窗: T1: on the 1st day; T2: on the 7th day in the RME group and in the 3rd or 4th month in the SME group; T3: on the 15th day in the RME group and between the 6th and 8th month in the SME group

Patients will be asked this question about any swelling in soft tissue (Item no 05): 'Do you have swelling in soft tissue?' A standardized questionnaire will assess pain, discomfort and functional impairments' levels during the active phase of treatment. The 4-point Likert scale will be used consisting of: (no), (mild), (moderate) or (severe). The patient will be asked to choose one of the four options.

Change in the levels of pain and discomfort

时间窗: T1: on the 1st day; T2: on the 7th day in the RME group and in the 3rd or 4th month in the SME group; T3: on the 15th day in the RME group and between the 6th and 8th month in the SME group

Patients will be asked this question about their feeling of pain and discomfort (Item no 01): 'What is the degree of pain/discomfort you have experienced?' A standardized questionnaire will be used to assess pain, discomfort and functional impairments' levels during the active phase of treatment. The patient will be asked to specify a point on the Visual Analogue Scale (VAS) which is a 10-cm horizontal line with two focal points at its beginning and end (0: there is no pain - 10: the worst pain). The score will be determined by measuring the distance from the beginning until the point identified by the patient.

Change in patient's perception of treatment ease

时间窗: T1: on the 1st day; T2: on the 7th day in the RME group and in the 3rd or 4th month in the SME group; T3: on the 15th day in the RME group and between the 6th and 8th month in the SME group

Patients will be asked this question about the ease of the treatment procedure (Item no 06): 'How easy is the treatment procedure?' A standardized questionnaire will assess pain, discomfort and functional impairments' levels during the active phase of treatment. The 4-point Likert scale will be used consisting of: (easy), (medium), (hard) or (very hard). The patient will be asked to choose one of the four options.

Change in the difficulty in swallowing

时间窗: T1: on the 1st day; T2: on the 7th day in the RME group and in the 3rd or 4th month in the SME group; T3: on the 15th day in the RME group and between the 6th and 8th month in the SME group

Patients will be asked this question about any difficulty in swallowing (Item no 03): 'Do you have difficulty in swallowing?' A standardized questionnaire will assess pain, discomfort and functional impairments' levels during the active phase of treatment. The 4-point Likert scale will be used consisting of: (no), (mild), (moderate) or (severe). The patient will be asked to choose one of the four options.
