Purpose:
To compare the treatment effect between one-visit and multiple-visit endodontic treatment for cracked tooth with pulpitis.
Methods:
The literatures published before 2016-06-01 regarding to one-visit and multiple-visit root canal treatment for cracked tooth with pulpitis were searched through MEDLINE, CNKI, VIP, Wanfang Database et al. Then the included studies were chosen according to the inclusion criteria. Collection of features, quality evaluation and analysis of treatment effect, follow-up results (half year/1 year) and postoperative pain of the included studies were analyzed using Stata/SE12.1 software.
Results:
A total of 24 Chinese literatures were included and no eligible foreign literatures were found. There were 3065 cases including 1608 with one-visit endodontic treatment and 1457 with multiple-visit endodontic treatment. Meta analysis showed that the effective rate (96.90%) and follow-up success rate (94.90%,94.60%) of one-visit endodontic treatment were significantly higher than multiple-visit one (84.00%,81.40%,89.00%),while there was no significant difference in postoperative pain [RR=0.96,95%CI (0.82,1.13)].The results did not change after sensitivity analysis. However,there were some differences in assignment methods and operations details among the literatures.
Conclusions:
The existing limited evidences show that one-visit endodontic treatment has higher effective rate than multiple-visit endodontic treatment and its postoperative pain is acceptable. However, more standard randomized controlled trials are needed.

Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
Types of Non-structural Cracks in Concrete
Plastic shrinkage cracks typically form within hours after the concrete is poured. The concrete's surface dries faster than the bottom, creating tensile stress that the still-plastic concrete cannot withstand, leading to diagonal or randomly patterned cracks on the concrete surface.
