This study investigated whether providing paper information leaflets (PILs) before performing dental procedures improved psychological well-being and reduced anxiety in Czech patients.</p><p><strong>Materials and methods: </strong>This parallel-group, single-blind randomized, prospective clinical trial was conducted at a private dental clinic in the Czech Republic in 2020. A total of 167 adult patients were randomly assigned to either the experimental group (<i>n</i> = 82), receiving both verbal information and a PIL, or the control group (<i>n</i> = 85), receiving only verbal information before their dental procedure (fillings, endodontic treatment, prosthetic restorations, or extractions). Pre- and post-procedure psychological well-being and anxiety were assessed using study-specific questionnaires. Data analysis was conducted in R using RStudio, with a significance level set at <i>P</i> < 0.05. Between-group differences were assessed while controlling for gender and education. Linear regression was used to analyze pre-procedure anxiety, and logistic regression was used to analyze post-procedure well-being outcomes (reporting \"everything was fine,\" \"unpleasant mouth sensations,\" and \"quick adjustment\"). The Benjamini-Hochberg correction was applied to control for multiple comparisons. Sensitivity analysis used the \"best-worst and worst-best case\" method to evaluate nonrandom missing data.

Post-procedure, while fewer patients in the PIL group reported that \"everything was fine\" (28/82 vs. 39/85), this difference was not statistically significant after correction for multiple comparisons (uncorrected <i>P</i> = 0.038, <i>α</i> _FDR = 0.01). No significant differences were found between groups regarding \"unpleasant mouth sensations\" (<i>P</i> = 0.84) or \"quick adjustment\" (<i>P</i> = 0.52).</p><p><strong>Conclusion: </strong>Providing PILs in addition to verbal information did not significantly impact pre-procedure anxiety or post-procedure well-being in this sample of Czech dental patients.

Mediotrusive (MT) occlusal contacts have been implicated in TMDs due to their potential to alter mandibular biomechanics and masticatory patterns.
