Clinical ResearchFactors Related to the Outcomes of Cracked Teeth after Endodontic Treatment
Section snippets
Materials and Methods
The study was approved by Boston University’s Institutional Review Board committee (institutional review board no: H-36879). A data set that contained root canal treatments performed at the Boston University Goldman School of Dental Medicine’s postgraduate clinic and that had at least 1-year recall examination data was obtained for the time period of January 1, 2010, through December 31, 2017. However, an exception was made to include any immediate failure that occurred within 1 year. The
Results
Sixty-two samples met the inclusion criteria and were included in this study. The mean age of the collected sample was 51.2 years old (standard deviation = 11.5 years), consisting of 27 men and 35 women. The most commonly observed teeth were molars (85%). Most of the samples were previously restored, with amalgam being the most common restoration material (Table 1). The most common pulpal and periapical diagnosis in cracked teeth was pulpal necrosis with symptomatic apical periodontitis
Discussion
A literature review revealed that multiple factors are related to higher incidence rates of cracked teeth including large restorations, posterior teeth, older populations, and excursive interferences, among others4, 5, 6. In the present study, cracked teeth were most commonly found in molars (85.5%) and within the age group of 41–60 years old (67.7%). The number of female samples was slightly higher (56.5%) than males (43.5%). Almost all (90.3%) of the samples had been previously restored, and
