Thank you. Papers seems to be precise to what i need.

The metrics can range from a symptom-free patient who can function on the tooth or teeth, to complete formation of normal apical anatomy (based on limited input from a two-dimensional radiograph). The biggest problem appears to be long-term evaluation of all procedures performed…that means a 100% evaluation of patients treated over at least  4-year period, using exacting radiographic documentation and thorough subject and objective  evaluation…avoiding practitioner bias This down not occur routinely and dilutes the information available. The articles provided above do not deal with these issues. The literature provides a vast amount of percentages of success or tooth retention…with a large amount of variables…and even though statistics are applied to these data, this does not mean that the findings are significant as there are many variable not accounted for. The best you can do is to provide quality root canal procedures using contemporary principles and follow you patients for as long as possible…view success as tooth retention and a content patient There is no magic bullet in this assessment. We all have failures and unless you are willing to assess your failures thoroughly you will never have a set of metrics to evaluate your outcomes in a unbiased and positive manner.

Dear sir,

clinical criteria for success are

1) no tenderness to percussion or palpation

2) no evidence of subjective discomfort

3) no sign of infection or swelling

4) no sinus tract or integrated periodontal disease

5) minimal to no scarring or discolouration

6) tooth having normal form, function and esthetics

Histological evaluation

1) Absence of inflammation

2) Regeneration of periodontal ligament fibres

3) Presence of osseous repair

4) Repair of cementum

5) Absence of resorption

6) Repair of previously resorbed areas
