Pain Perception Before Endodontic Treatment: from Primary Care to Specialized Care

Objective: To analyze patients’ pain perception requiring endodontic treatment referred to a Dental Specialties Center. Material and Methods: Data was collected through a self-administered questionnaire for patients about their experience of pain and another for endodontists about the treatment performed. The results were analyzed descriptively using Pearson’s Chi-square test and Fisher’s Exact test, with Bonferroni correction (p≤0.05). Results: The median age of the patients was 39 years, and 71.1% were female. The median waiting time for treatment was five months. Pain was reported by 75.2% of patients, occurred more than one month earlier (63.6%), with moderate/severe intensity (66.9%), and most patients sought emergency treatment more than once (79.1%). In addition, pain was associated with sex (female; p=0.008); moderate/severe intensity (p<0.001); the number of times that patient had to go to the dentist because of the tooth treatment (twice or more; p=0.002); and type of tooth treated (posterior tooth; p=0.002). Conclusion: Severe pain episodes resulted in a repeated search for emergency services, which may overload the primary care service, especially if the waiting time for endodontic treatment is long
