          Pulpitis is one of the common diseases indicated by the department of stomatology that is located in the tooth and contains abundant nerve vessels. In order to evaluate the pain degree and functional recovery of patients after treatment by visual analogue pain scale (VAS) and temporomandibular joint function score, a retrospective analysis was performed on 128 patients diagnosed with pulpitis who received root canal treatment in the department of stomatology from January 2020 to March 2021. The results show that 3%NaClO combined with 0.9% sodium chloride injection can effectively relieve the pain degree of patients after treatment, and the antibacterial effect is significantly better than 3%H 2O 2 combined with 0.9% normal saline. Meanwhile, it can effectively improve the temporomandibular joint function and reduce the recurrence rate, which has good clinical application value.

          The Visual Analogue Scale for Rating, Ranking and Paired-Comparison (VAS-RRP): A new technique for psychological measurement

          Traditionally, the visual analogue scale (VAS) has been proposed to overcome the limitations of ordinal measures from Likert-type scales. However, the function of VASs to overcome the limitations of response styles to Likert-type scales has not yet been addressed. Previous research using ranking and paired comparisons to compensate for the response styles of Likert-type scales has suffered from limitations, such as that the total score of ipsative measures is a constant that cannot be analyzed by means of many common statistical techniques. In this study we propose a new scale, called the Visual Analogue Scale for Rating, Ranking, and Paired-Comparison (VAS-RRP), which can be used to collect rating, ranking, and paired-comparison data simultaneously, while avoiding the limitations of each of these data collection methods. The characteristics, use, and analytic method of VAS-RRPs, as well as how they overcome the disadvantages of Likert-type scales, ranking, and VASs, are discussed. On the basis of analyses of simulated and empirical data, this study showed that VAS-RRPs improved reliability, response style bias, and parameter recovery. Finally, we have also designed a VAS-RRP Generator for researchers’ construction and administration of their own VAS-RRPs.
