ABSTRACT
Purpose@#The aim of this study was to evaluate the relationship between the patient's occlusion and a cracked tooth by using T-scan occlusal analysis and a quantitative light-induced fluorescence (QLF) technology. @*Materials and Methods@#This study was carried out on 51 patients having cracked teeth between January, 2019 and December, 2020. The tooth crack was determined with a Q-ray pen and QLF parameters (ΔFmax and ΔRmax) were obtained by a Q-ray software. T-scan tests were conducted to all subjects and then, the occlusal force and disclosing time were analyzed. Mann-Whitney U test was performed to compare the occlusal force and disclosing time between cracked teeth groups and contra-lateral normal teeth groups (α = .05). Mann-Whitney U test was performed to compare ΔFmax and ΔRmax according to the results of cold/bite tests (α = .05). A Spearman correlation analysis was run to determine the relationship between ΔFmax or ΔRmax and occlusal force or disclosing time (α=.05). @*Results@#The mean occlusal force and disclosing time were significantly higher on cracked teeth than on normal teeth (P .05). There was no correlation between ΔFmax or ΔRmax and occlusal force or disclosing time (P > .05). @*Conclusion@#There was a significant relationship between occlusion and cracked tooth syndrome. QLF has the potential to be a valuable tool for the diagnosis of tooth crack in clinical practice.
