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 .
The effect of the Relaxodont brain wave synchronizer on endodontic anxiety: evaluation by galvanic skin resistance, pulse rate, physical reactions, and questionnaire responses.
The effects of a brain wave synchronizer ( BWS ) on endodontic ( root canal ) anxiety  was evaluated in the clinical practice s of the senior author . The experimental groups were : ( 1 ) a verbal method ( routine calming words by dentist ) plus BWS ( N = 10 ) and ( 2 ) verbal method plus BWS and alpha relaxation tape ( N = 10 ) . The control group was verbal method alone ( N = 10 ) . All three groups were evaluated during a complete endodontic treatment by the use of galvanic skin resistance ( GSR ) , pulse rate ( PR ) , physical responses , and pre- and post-treatment question naires . Recordings were made during the following periods : ( 1 ) start ; ( 2 ) local anesthetic injection ; ( 3 ) rubber dam application ; ( 4 ) drilling ; ( 5 ) x-ray taking ; ( 6 ) instrumentation ; ( 7 ) obturation ; and ( 8) conclusion . Results showed that the experimental groups were significantly better than the control group in the reduction of endodontic anxiety . The findings reinforced the belief that local anesthetic injection is the most anxiety producing aspect of endodontic treatment
