| Abstract: | Objective To study the relation between masticating hard food and vertical root fracture. Methods 14 cases of vertical root fracture from two hospitals and their controls (matched with the ratio of 1:4) were investigated. The main contents were conditions of their masticating hard food. The results of investigations were identified by chi square test. Results x 2= 16.50 ( P < 0.01 ),the OR is 13.00 ,and its 95% confidence interval is between 3.77 and 44.85 , ARP is 92.31 % yet PARP is 79.12 %. Conclusion the correlation between masticating hard food and vertical root fracture exists. |
