Percentage of cases of patients that present post-operatory pain after endodontic treatment procedure in one visit or in more than one visit

Abstract

Introduction: The post-operative pain is a very prevalent adverse effect after an endodontic treatment. It is indeed of greater importance, that many associated factors can interfere in the incidence of this pain. Objectives: The main objective was to establish percentages of patients suffering pain post-endodontic treatment. We established the potential association of risk and preventive factors with the incidence of post-operative pain. Methodology: To collect our results, we distribute questionnaires addressed to 134 patients about characteristics of their endodontic treatment and rate their pain at different periods from 0 to 10. We direct a cohort studies, elaborating percentages, risk ratios and P-values of our results. We compared our results with previous published studies related to this subject. Results: Results showed that 29% of patients did experienced pain between 1 hour and 1 day after the treatment whereas 3,7% suffered persistent pain after a week. 57% of symptomatic irreversible pulpitis referred pain, compared to 47% of patient retreated, 17% of necrotic pulp, and 11% of asymptomatic irreversible pulpitis. Regarding potential associated factors, being a woman OR = 1,53, being young OR = 0,48, being older OR = 0,75, mandibular teeth OR = 0,32, complexes anatomy OR = 3,33. Multiple visits treatment have not shown significantly more risk of pain than single visits one. Conclusions: The number of patients integrated in our study did not permit elaborate concrete relationship between associated factors and post-operative pain. However, compared with previous studies, it suggested that we expect a prevalence of post-operative pain around 30%, that tends to decrease with weeks to 3-4% of persistent pain. Without sufficient significance, needing more studies, post-operative pain seems to be associated with female of middle age, multiple visits treatment, complicated posterior teeth anatomy, and symptomatic irreversible pulpitis diagnosis.
