Five-year Changes in Periodontal Parameters after Apical Surgery

Prognostic factors on periapical surgery: A systematic review

“…A study performed by von Arx et al . ( 2 ) found that the type of incision technique significantly affected changes in the gingival margin during the first year, both at the facial and lingual sites. The sub marginal incision permitted a gain in gingival margin of 0.02 and 0.01 mm at the facial and lingual sites, respectively.…”

“…The main objective of periapical surgery is to seal the root canal system, thereby enabling healing by forming a barrier between the irritants within the confines of the afected root and the periapical tissue. The success of periapical surgery is usually determined by both radiological signs and clinical signs and symptoms ( 1 , 2 ).…”

Five-Year Longitudinal Assessment of the Prognosis of Apical Microsurgery

“…The risk, especially in the longer-term, is that an apicomarginal bacterial pathway may develop over time when the crestal bone level is already compromised at the time of apical microsurgery (24). Such communication may not only compromise periapical healing, but it can also lead to a significant loss of periodontal attachment in the long-term, as observed in teeth that did not heal after apical microsurgery (26). Therefore, from the clinical perspective, the supporting bone level should be assessed preoperatively and carefully considered before the tooth is subjected to apical microsurgery (24).…”

Does the Papilla Preservation Flap Technique Induce Soft Tissue Modifications over Time in Endodontic Surgery Procedures?

“…These results could be comparable with those found in the present study regarding the affected tooth. One other study by von Arx et al (27) confirmed that gingival tissue recession was very low after 1 year (0.16 mm) and remained stable over time (ie, 0.24 mm after 5 years).…”
