RESULTS Application of the Oral Health Impact Profile ( OHIP ) demonstrated that disease of pulpal origin affects quality of life with moderate severity , primarily through physical pain and psychological discomfort , and that RCT results in broad improvement of quality of life .
Satisfaction with RCT is extremely high , but cost is the primary reason for dissatisfaction .
Anxiety and fear affect RCT patients , profoundly influencing their behaviors , including treatment avoidance , and their pain experience .
Fear of pain is " fair " to " very much " prior to RCT .
Pain is widely feared , disliked , and remembered ; however , disease of pulpal origin generally produces moderate , but not severe pain .
RCT causes a dramatic decrease in pain prevalence and severity over the week following treatment .
Survival rates of teeth after RCT are very high ; complication rates are low .
Cost is a barrier to RCT , but initial costs , lifetime costs , cost effectiveness , cost utility , and cost benefit all compare extremely well to the alternatives involving replacement using implants or fixed prostheses .
INTRODUCTION Root canal treatment ( RCT ) success criteria inform us of the path to bony healing and of prognostic factors , but tell little about how the patient perceives , feels , or values RCT .
Patients choose , undergo , and pay for RCT , they live with the result , and inform their community .
The purpose of this narrative review was to appraise patient-centered outcomes of initial non-surgical RCT and nonsurgical retreatment , in adults .
Effect of prophylactic amoxicillin on endodontic flare-up in asymptomatic, necrotic teeth.
The purpose of this prospect i ve , r and omized , double-blind , placebo-controlled study was to determine the effect of prophylactic amoxicillin on the occurrence of endodontic flare-up in asymptomatic , necrotic teeth . Seventy patients participated and had a clinical diagnosis of an asymptomatic , necrotic tooth with associated periapical radiolucency . One hour before endodontic treatment , patients r and omly received either 3 g of amoxicillin or 3 g of a placebo control in a double-blind manner . After endodontic treatment , each patient received : ibuprofen ; acetaminophen with codeine ( 30 mg ) ; and a 5 1/2-day  diary  to record pain , swelling , percussion pain , and number and type of pain medication taken . The results demonstrated 10 % of the 70 patients had a flare-up characterized by moderate-to-severe postoperative pain or swelling that began approximately 30 h after endodontic treatment and persisted for an average of 74 h. Of the seven patients who had flare-ups , 4 were in the amoxicillin group and 3 were not . Prophylactic amoxicillin did not significantly ( p = 0.80 ) influence the endodontic flare-up . We concluded that a prophylactic dose of amoxicillin before endodontic treatment of asymptomatic , necrotic teeth had no effect on the endodontic flare-up
