Abstract：
OBJECTIVE: Temporomandibular disorder (TMD) is the term used to describe a pathology (dysfunction and pain) in the masticatory muscles and temporomandibular joint (TMJ). There is an apparent upward trend in the publication of dental research and a need to continually improve the quality of research. Therefore, this study was conducted to analyse the use of sample size and effect size calculations in a TMD randomised controlled trial.
METHODS: The period was restricted to the full 5 years, i.e., papers published in 2019, 2020, 2021, 2022, and 2023. The filter article type-\"Randomized Controlled Trial\" was used. The studies were graded on a two-level scale: 0-1. In the case of 1, sample size (SS) and effect size (ES) were calculated.
RESULTS: In the entire study sample, SS was used in 58% of studies, while ES was used in 15% of studies.
CONCLUSIONS: Quality should improve as research increases. One factor that influences quality is the level of statistics. SS and ES calculations provide a basis for understanding the results obtained by the authors. Access to formulas, online calculators and software facilitates these analyses. High-quality trials provide a solid foundation for medical progress, fostering the development of personalized therapies that provide more precise and effective treatment and increase patients\' chances of recovery. Improving the quality of TMD research, and medical research in general, helps to increase public confidence in medical advances and raises the standard of patient care.

摘要：
目的：颞下颌关节紊乱病（TMD）是用于描述咀嚼肌和颞下颌关节（TMJ）的病理（功能障碍和疼痛）的术语。牙科研究的出版有明显的上升趋势，需要不断提高研究质量。因此,本研究旨在分析TMD随机对照试验中样本量和效应量计算的使用.
方法：期限限制为整整5年，即，2019年、2020年、2021年、2022年和2023年发表的论文。使用过滤器文章类型-“随机对照试验”。这些研究以两级量表进行分级：0-1。在1的情况下,计算样本量(SS)和效应量(ES)。
结果：在整个研究样本中，58%的研究中使用了SS，而15%的研究使用ES。
结论：质量应该随着研究的增加而提高。影响质量的一个因素是统计水平。SS和ES计算为理解作者获得的结果提供了基础。访问公式,在线计算器和软件促进了这些分析。高质量的试验为医学进步提供了坚实的基础,促进个性化疗法的发展，提供更精确和有效的治疗，增加患者康复的机会。提高TMD研究的质量，和一般的医学研究，有助于增加公众对医疗进步的信心，并提高病人护理的标准。
