本研究建構了一套智慧牙刷物聯網閘道器在多人的環境中使用，使用者學習完刷牙正確姿勢後，可以在家裡刷牙時利用手機比對自己目前刷牙的姿勢與貝氏刷牙法的有何不同。研究中開發智慧牙刷物聯網閘道器和牙醫雲端系統，智慧牙刷物聯網閘道器包含了藍牙通訊、GUI動畫呈現和SQLite資料庫，負責處理接收刷牙區塊、顯示刷牙流程及編碼並儲存個人刷牙資訊。牙醫雲端系統包含MQTT Broker與MQTT Client for Server、雲端資料庫及牙醫監測軟體，負責接收並解碼個人刷牙資訊、分析刷牙時間及顯示不同使用者的刷牙資訊給牙醫師。研究中對系統進行一連串的測試，其中包含刷牙區域判別與MQTT傳輸。在刷牙區域判別中，智慧牙刷會依序或亂數變更刷牙區塊，並讓每區塊都可以達到50次的測試，在結果可以觀察到即便變更刷牙區塊，閘道器程式也可正確判斷區塊的位置，此外在MQTT傳輸測試中，三位使用者會傳送300筆不同的Topic資料至MQTT Broker，測試MQTT Client for APP、MQTT Broker及MQTT Client for Server對資料處理能力，其結果表示MQTT Client for APP、MQTT Broker及MQTT Client for Server對於傳送或讀取都維持高度正確性。

This study established a set of smart toothbrush networking gateway for use in an environment with many people. This enables users to compare whether their current tooth brushing technique is different from the Bass technique of tooth brushing by using their mobile phone after they have learnt the correct method of tooth brushing. The user’s tooth brushing records are obtained using this system and transmitted to the cloud-based server designed in this study using MQTT. Thus, in an environment with many people, each person can use their own smart toothbrush for tooth brushing and the mobile phone gateway program will show the time taken for tooth brushing and level of completion, so that everyone can understand and maintain oral health. Dentists can also use this system to understand their patients’ current tooth brushing status, so that patients and dentists can achieve a better dentist-patient relationship.
