A clinical radiographic retrospective assessment of the success rate of single‐visit root canal treatment

Abstract

Seven hundred and sixty-eight single-visit cases, of which 223 presented for a re-examination appointment ranging from 6 months to 4 years from the day of treatment, were considered. Four endodontists provided examinations for both root canal treatment and re-examinations. Clinical and radiographic data were used to form an overall impression of the outcomes for each case at the time of re-examination. Available demographics and treatment information of these 223 cases were compiled for comparison. The number of treatment visits was not determined by a pretreatment diagnosis or a re-assessment of the pulp status upon entry into the tooth; therefore both vital and necrotic cases, as well as those with and without periradicular pathosis, were included. Statistical analysis was carried out using Chi-square tests and considered variations in failure rates based on gender, provider, tooth type, position and arch. A t-test was used to evaluate data on age. The overall success rate was 89.2%. No statistically significant differences were seen based on gender, age, arch or provider. Statistically, anterior teeth were more successful than posterior teeth.

The Effect of the Distance Between Post and Residual Gutta-Percha on the Clinical Outcome of Endodontic Treatment

“…In the molar group, a gap of Ͼ2 mm between the post and the gutta-percha resulted in an unfavorable clinical outcome in all the teeth examined. These results are compatible with the findings of some studies, in which anterior tooth treatment are associated with a more favorable outcome than that of posterior teeth (2,23,29), although not with those of others (25,30). Despite the fact that they dealt with different factors related to the clinical outcome of treatment, it is likely that the anatomy of a multirooted tooth presents a greater challenge for the operator, especially for an undergraduate student.…”

“…The position of the tooth in the arch had no significant influence as previously reported in studies regarding other aspects of the clinical outcome of endodontic treatment (29,31).…”

Single Visit Endodontic in the Management of Symptomatic Irreversible Pulpitis and Pulp Necrosis with Apical Periodontitis: Report of Two Cases

“…Minute differences in periapical healing were observed among individuals undergoing single visit and multiple visit root canal treatment and bacterial growth at the second appointment had a significant negative impact on healing of the periapical lesion [4,5]. In addition to this, the clinical efficacy of sodium hypochlorite irrigation in the control of root canal infection is much more than the effectiveness of interappointment calcium hydroxide dressing, in disinfecting the root canal system and treatment outcome, indicating the need to develop more efficient inter-appointment dressings [6,7]. E. faecalis is the most resistant bacterium against calcium hydroxide while sodium hypochlorite is effective against it in both buffered and unbuffered states [8].…”

“…Recent studies have shown little or no difference in the quality of treatment or success rates between single-and multiple-visit root canal treatment [5][6][7][8][9].…”

“…With the advent of new instrumentation techniques, material science and technology, it is no more an orthodox empirical procedure for obturation of root canals [7]. However, with the introduction of magnifying loupes surgical microscopes, NiTi rotary instrument systems, ultrasonic devices, newer obturation systems (injectable obturation system), it is now considered as an acceptable alternative treatment procedure for endodontic problems [8].…”
