# Dentin Bond Strength of Calcium Silicate-Based Materials: A Systematic Review of In Vitro Studies
## 3 Results
### Quality Assessment  
Table 3 presents the results of the quality assessment, indicating an average compliance of 78% among the included studies. The scores ranged from a minimum of 64% to a maximum of 91%. Across the 42 articles reviewed, a consistent pattern emerged in terms of data quality, with clear introductions, objectives, and/or hypotheses (items 1 and 2). Methodological data and results were systematically presented (items 3 and 4), while only 17 articles addressed the calculation of sample size (item 5).

Table 3: Quality assessment of the included studies.  
Notably, points 6 to 9, which pertain to the randomization process, were not fulfilled by any of the studies. However, all studies reported the statistical analyses performed, presenting results along with their significance levels or confidence intervals (items 10 and 11). Fifteen out of the 42 articles acknowledged and addressed possible limitations in their methodologies (item 12).  
Concerning funding sources, with the exception of two studies, all articles disclosed any financial support received (item 13). Interestingly, none of the articles referenced an available protocol (item 14).
