Abstract
Aim To investigate predisposing aspects related to the indication for root canal treatment (RCT) at Dental Schools of Brazil. Methods Data of 207 patients referred to endodontic treatment at undergraduate Dental Schools of Brazil were collected over a period of 8 months. Patient-related data included age, gender, first dental visit, tooth brushing frequency, number of remaining teeth, and previous endodontic treatment, and tooth-related information regarding number, type, and location in the mouth of teeth that need RCT, waiting time for the endodontic treatment, endodontic diagnosis, pain report, and dental crown condition was collected for each participant. Bivariate analysis (Chi-square test; p < 0.05) associated gender and tooth/patient-related conditions. Poisson regression analysis compared multiple endodontic need and exposure variables. Results Patients were mainly comprised of women (65.2%), aged 18–39 years (69.6%). Previous RCT was significantly more prevalent in women when compared to men (p=0.005). First dental visit at later moment (after 20 years of age) demonstrated 400% greater prevalence of multiple RCT demand when compared to patients that attended the dental office at age below seven years (p=0.032). Most of the patients presented only one tooth needing RCT (80.2%), mainly premolars (44.9%). Interestingly, women underwent more RCT in maxillary teeth (p=0.016) and significantly contributed with their report to the diagnosis process when compared to men (p=0.014). Regarding dental crown condition, 45.4% of all teeth registered unsatisfactory restorations, which were more pronounced in female patients (p=0.018). Unsatisfactory restorations or dental caries had 75% and 82%, respectively, less prevalence of multiple RCT indication when compared to sound dental crown (p=0.001). Conclusions RCT was undertaken more frequently in young female adults' premolars presenting unsatisfactory restorations. First dental visit, number of teeth with previous endodontic treatment, tooth group, and dental crown condition were significantly associated with the necessity of multiple endodontic treatments.
Highlights
Worldwide population has extended life expectancy in 10 years, requiring all kinds of health care, including dentistry, to achieve a better quality of life (QOL) [1]
Some less favored population in the world may not afford a root canal treatment (RCT), and the only other option to reach oral health relies on tooth extraction/loss, which may lead to an unhealthy-look dentition and to social isolation, limited participation in community activities, and negative judgement toward society [2]
The reciprocity connecting RCT to unsatisfactory restorations can build new perspectives for efficient preventive protocols, since few studies have investigated the association between toothcrown condition and the indication for endodontic treatment [9, 14]. us, this study aimed to assess the dental crown-related conditions and patient dental history as possible influencing factors to the necessity of RCT in the northeast region of Brazil, testing the hypothesis that dental history of patients and tooth previous structure conditions do not influence the number of teeth requiring root canal treatment
Summary
Tooth- and Patient-Related Conditions May Influence Root Canal Treatment Indication. Patient-related data included age, gender, first dental visit, tooth brushing frequency, number of remaining teeth, and previous endodontic treatment, and tooth-related information regarding number, type, and location in the mouth of teeth that need RCT, waiting time for the endodontic treatment, endodontic diagnosis, pain report, and dental crown condition was collected for each participant. Previous RCT was significantly more prevalent in women when compared to men (p 0.005). 45.4% of all teeth registered unsatisfactory restorations, which were more pronounced in female patients (p 0.018). Unsatisfactory restorations or dental caries had 75% and 82%, respectively, less prevalence of multiple RCT indication when compared to sound dental crown (p 0.001). Number of teeth with previous endodontic treatment, tooth group, and dental crown condition were significantly associated with the necessity of multiple endodontic treatments
