EXPERIMENTAL BASED STATISTICAL ANALYSIS FOR DENTAL CHAIR FAILURES

Abstract

With the improvement of people’s living standards and the enhancement of oral health awareness, oral health has been paid more and more attention. The dental clinic of most domestic hospitals is often overcrowded, and the number of patients treated every day is much higher than in some foreign hospitals. The dental unit is a piece of essential medical equipment in the clinic. The need to improve the dental unit, as the dental chair is an important vital tool in modern dentistry. The purpose of this research is to provide therapeutic solutions, to discuss the main common malfunctions and the development of the dental unit, and to find the most appropriate solutions available to it. In this project, the hand piece was developed and the user's performance was improved by developing lighting. A dental unit malfunction survey was conducted and a dentists requirements survey was conducted that will enhance the unit's performance. Collected from surveys and found the most common malfunctions. The lighting unit was chosen for development. Most of the questionnaire items could affect the overall satisfaction with the dental unit chair. Additionally, because the design and appearance quality, maintenance, and overall satisfaction with the water fountain and cuspidor may have the greatest impact on the overall satisfaction with the dental unit chair, the improvement of these elements may bring about the enhancement of the overall satisfaction.
