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 (¥ÄFmax and ¥ÄRmax) 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 (¥á = .05). Mann-Whitney U test was performed to compare ¥ÄFmax and ¥ÄRmax according to the results of cold/bite tests (¥á = .05). A Spearman correlation analysis was run to determine the relationship between ¥ÄFmax or ¥ÄRmax and occlusal force or disclosing time (¥á=.05).

Results: The mean occlusal force and disclosing time were significantly higher on cracked teeth than on normal teeth (P < .05). The ¥ÄFmax or ¥ÄRmax were not significantly different according to the results of cold/bite tests (P > .05). There was no correlation between ¥ÄFmax or ¥ÄRmax 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.
