Description

The purpose of this study was to investigate the usability of a lip and cheek retractor with soft material （LR-soft） in special needs dentistry.<br>In adult volunteers, the characteristics of the intraoral visual field by using LR-soft and the lip retractor were evaluated by an imaging study.<br>The size of area was shown to be smaller with LR-soft. The oblateness was shown to be significantly lower with LR-soft. The mobility of the lip, when the lip was pulled to the right side, was measured by the difference in horizontal length on the right and left sides independently, and the length was shown to be significantly longer with LR-soft （right p＜0.01, left p＜0.05）.<br>The impression of using LR-soft and the lip retractor was evaluated by using the modified Visual Analogue Scale （VAS）. Upon comparing the feeling when applied, soreness, and impression after using for 5 minutes, LR-soft showed significantly fewer complaints （p＜0.01）.<br>The degree of gaining the visual field by using LR-soft when tooth brushing was done by disabled persons was compared, using criteria for the difficulty of retracting the lips in the case of using LR-soft and by finger. Significantly less difficulty was shown when using LR-soft （p＜0.01）. The area where brushing was not performed due to the difficulty of retracting the lips was smaller with LR-soft.<br>Based on these findings, LR-soft provided a sufficient intraoral visual field and resulted in fewer complaints. Therefore, it is considered that LR-soft is suitable for disabled persons who present with ridged mouth closure in whom it is difficult to carry out treatment or oral care.
