The purpose of the study was to comparatively evaluate temporomandibular joint function and treatment response using joint vibration analysis (JVA) in patients exhibiting disc displacement with reduction (DDR), treated with three variable thickness of stabilization splints. JVA analyzed these vibrations to detect internal joint abnormalities, and their patterns were further categorized using the Piper classification was highly accurate and hence used over magnetic resonance imaging.
Randomized clinical trial.
The splint of different thicknesses, i.e., Group A (3 mm), Group B (4 mm), and Group C (5 mm) were given to the study participants for 10 week interval, and pre and posttreatment efficacy was recorded using JVA. Stress perseverance and tooth wear index were recorded with a pre and postquestionnaire.
The one way analysis of variance f test and Turkey's post hoc test for multiple comparisons were used to statistically assess the results.
The treatment response with Group A and B thickness of stabilization splints was significant (P = 0.01) and with Group C was not significant (P = 5.28). The statistical result of stress perseverance was not significant between the three groups, although reflecting female participants were affected more. The tooth wear index was significant with all the three groups (P = 0.09).
The study concluded that the splints given to Group A and Group B showed effective treatment response, while Group C showed positive response in a few individuals, but some individuals compliant of discomfort. The stress level was high in female individuals. Among all the participants, the concern of tooth wear was present.
本研究旨在比较评估采用关节振动分析(JVA)对可复性盘移位(DDR)患者使用三种不同厚度的稳定矫治器治疗时的颞下颌关节功能及治疗反应。JVA通过分析这些振动来检测关节内部异常,并且其模式使用派珀分类法进一步分类,该分类法高度准确,因此优于磁共振成像。
随机临床试验。
将不同厚度的矫治器,即A组(3毫米)、B组(4毫米)和C组(5毫米)给予研究参与者,间隔10周使用,使用JVA记录治疗前后的疗效。通过前后问卷记录应激耐力和牙齿磨损指数。
采用单因素方差分析f检验和用于多重比较的土耳其事后检验对结果进行统计学评估。
A组和B组厚度的稳定矫治器的治疗反应显著(P = 0.01),C组不显著(P = 5.28)。三组之间应激耐力的统计结果不显著,尽管显示女性参与者受影响更大。所有三组的牙齿磨损指数均显著(P = 0.09)。
该研究得出结论,A组和B组的矫治器显示出有效的治疗反应,而C组在少数个体中显示出阳性反应,但一些个体抱怨有不适感。女性个体的应激水平较高。在所有参与者中,都存在对牙齿磨损的担忧。
