“…An early meta-analysis reported that these microsurgeries are 1.58 times more successful than traditional surgeries with cumulative success rates of 93.52% after 6 month follow-up [ 4 ]. Their long-term success (>4 years, 82.5%) [ 5 ] and survival (8.7 years, 74%) [ 6 ] are comparable to nonsurgical retreatment. However, long-term cumulative success rates for microsurgeries in cohorts have not been reported.…”

The aim of this study was to analyze the long-term outcomes of endodontic microsurgeries in a cohort and identify their association with prognostic factors. A cohort of endodontic microsurgeries followed up periodically with complete clinical and radiographic records for at least 5 years were reviewed retrospectively. Their survival and healing status and profile characteristics were analyzed by Pearson chi-square test and logistic regression (α = 0.05) to identify prognostic factors that influenced outcomes. Of 652 cases in the cohort, 225 (34.5%) were included. The mean follow-up period was 90.4 months (range, 60–168 months). The long-term success rate was 80.5%, and the 5-year survival rate was 83.5%. Logistic regression showed higher success in anteriors compared to molars (OR = 5.405, (95% CI, 1.663–17.571; p = 0.005)) and in teeth with crown restorations (OR = 10.232, (95% CI, 3.374–31.024; p < 0.001)). Conversely, lower success was found in teeth with periodontal disease (OR = 0.170, (95% CI, 0.032–0.900; p = 0.037)) and maxillary sinus involvement (OR = 0.187, (95% CI, 0.035–0.994; p = 0.049)). Endodontic microsurgery has a highly favorable long-term outcome. Tooth position, crown restoration, periodontal disease, and maxillary sinus involvement were identified as main prognostic factors.

“…It is the recommended therapy for endodontically treated teeth with unresolved periapical lesions when the prognosis of secondary non-surgical root canal treatment is questionable 45. In comparison to the traditional apical surgical technique wherein the osteotomy is inherently large, modern surgical technique advocates a smaller access through the cortical bone in order to visualize, enucleate, and manage the resected root end.…”

Apicoectomy of maxillary anterior teeth through a piezoelectric bony-window osteotomy: two case reports introducing a new technique to preserve cortical bone

2016

Two case reports describing a new technique of creating a repositionable piezoelectric bony window osteotomy during apicoectomy in order to preserve bone and act as an autologous graft for the surgical site are described. Endodontic microsurgery of anterior teeth with an intact cortical plate and large periapical lesion generally involves removal of a significant amount of healthy bone in order to enucleate the diseased tissue and manage root ends. In the reported cases, apicoectomy was performed on the lateral incisors of two patients. A piezoelectric device was used to create and elevate a bony window at the surgical site, instead of drilling and destroying bone while making an osteotomy with conventional burs. Routine microsurgical procedures - lesion enucleation, root-end resection, and filling - were carried out through this window preparation. The bony window was repositioned to the original site and the soft tissue sutured. The cases were re-evaluated clinically and radiographically after a period of 12 - 24 months. At follow-up, radiographic healing was observed. No additional grafting material was needed despite the extent of the lesions. The indication for this procedure is when teeth present with an intact or near-intact buccal cortical plate and a large apical lesion to preserve the bone and use it as an autologous graft.

“…In a long-term perspective the orthograde retreatment of the root filling offers a more favorable outcome, 83% versus 72% for periapical surgery after 4-6 years [9]. In contrast to that a meta-analysis from Kang et al revealed a significantly higher success rate for periapical surgery in a short term perspective (less than 4 years) compared to orthograde retreatment, whereas no significant difference could be detected after more than 4 years [10]. Another study has reported a success rate of 62% when performing a revision procedure [11].…”

Aim: The first aim of this study was to evaluate the healing outcome after periapical surgery performed using an ultrasonic cleaning technique in conjunction with the use of either Intermediate Restorative Material (IRM) or mineral trioxide aggregate (MTA) as a retrograde root-end seal in teeth with apical periodontitis. A second aim was to determine if the type of coronal restoration had any impact on the healing outcome. Methodology: One hundred eighty-six consecutive teeth in 177 patients referred for periapical surgery were randomly allocated into two parallel groups, receiving either IRM or MTA as a retrograde root-end seal. The patients were reviewed 12 months after surgery. Fisher's exact test and Z-test analysis were performed. Results: One hundred sixty-six teeth in 158 patients were reviewed 12 months after surgery. Radiological evaluation and clinical examination revealed an 86% success rate for the IRM group and 85% for the MTA group. There was no statistically significant difference (p=0.829) between the two groups regarding the healing outcome (Fisher's test). The type of coronal restoration (p=0.575) had no impact on the healing outcome (Z-test). Conclusions: The tested materials, IRM and MTA, are both suitable as retrograde root-end filling materials in conjunction with an ultrasonic root-end preparation technique according to the results at the 12-month follow-up. The results of this study also show that the type of coronal restoration had no impact on the healing outcome following periapical surgery.

Outcome of nonsurgical retreatment and endodontic microsurgery: a meta-analysis

Abstract: Clinicians may consider the microsurgery as an effective way of retreatment as well as nonsurgical retreatment depending on the clinical situations.
