用影像處理分析技術分析顳顎關節症候群患者下顎髁頭圓度之變異性
Investigate the roundness variations of condyle head of the temporomandibular disorders (TMD) patients with the image processing and analysis technique
摘要
本研究主要藉由影像分析技術，進行對門診常規檢查中的口腔環口放射線攝影的下顎髁頭圓度之分析。並藉由下顎髁頭圓度的數據，期望建立一套新的顳顎關節症候群評估參數與指標。利用在醫院門診常規取得求診患者之環口放射線攝影影像，經影像處理技術取得下顎髁頭圓度，先以Kruskal-Wallis檢定和變異數分析確定本研究設計經影像處理技術取得下顎髁頭圓度方法的可行性；再將取得之患者環口放射線攝影影像，分為有症狀（SS）與無症狀（NoSS），自患者之環口放射線攝影影像，取得下顎髁頭圓度之實驗數據，再以t檢定分析其統計意義。本研究所設計之環口放射線攝影影像處理技術取得下顎髁頭圓度的方法，經Kruskal-Wallis檢定和變異數分析後，p值均低於.05，證實方法之可行性；另外，在分組研究結果中，患者之下顎髁頭圓度數據，也以t檢定發現p值低於.05，因此本研究設計的下顎髁頭圓度指標在有症狀（SS）與無症狀（NoSS）兩組中，具有統計上的意義。這代表下顎髁頭圓度指標可能成為一套新的顳顎關節症候群評估參數與指標。

Purpose: The purpose of the study was to analyze the roundness variations of condyle head in routine panoramic radiographic examination and establish a new evaluation system for temporomandibular disorders (TMDs). The panoramic radiographs of patients from hospital clinic were collected and processed to obtain the round variation of each condyle head. The processing method was analyzed with Kruskal-Wallis test and ANOVA. Then patients were divided into two groups: one was symptomatic TMDs (SS); one was no TMDs (NoSS). The roundness variations of each group were obtained and analyzed with t-test. The image processing technique of panoramic radiograph for roundness variation of condyle was confirmed to be feasible by Kruskal-Wallis test and ANOVA with p-value < .05. The results between groups were analyzed to be significant by t-test with p-value < .05. Therefore, the roundness variation of condyle head may be a new reference parameter of TMDs.
