Retrospective Evaluation of Surgical Endodontic Treatment: Traditional versus Modern Technique

Sealing ability of MTA and amalgam in different root-end preparations and resection bevel angles: an in vitro evaluation using marginal dye leakage

“…The area exposed after apicoectomy using both instruments was not significant. This is in agreement with the findings of Lin et al (16), who demonstrated that a preparation A review of clinical studies on dental materials used in retrofillings showed that amalgam was the most frequently used material in control groups; MTA was presented as a promising material for root-end filling (2,3,7,9). Advantages associated with amalgam are its low cost, easier handling, and clinical success (1,3).…”

“…Apicoectomy at a 90 o angle only became clinically possible with the use of ultrasonic retrotips in the preparation of root-end cavities (14). The use of ultrasonic retrotips is indicated when there is a substantial risk of root perforation or when access to the apex is limited (7). Despite of these potential differences, this study showed none significant difference in terms of microleakage when comparing the use of retrotips and carbide burs in a micro-handpiece.…”

“…A 45 o buccolingual bevel is an option to facilitate the material insertion, and can be indicated when conventional handpiece is used for cavity preparation. However, it could increase the apical leakage because the permeability of the dentin tubules are more exposed by the bevel angle (2,7). In opposite, the ultrasonic instruments appear as an option for root-end preparations using perpendicular apex resections.…”

Current strategy for successful periradicular surgery

“…Location, cleaning, and filling of the apical root canal are believed to be key requirements in achieving a predictable outcome after periradicular surgery (5,33). Periradicular surgery can be performed using traditional or modern techniques.…”

A clinical guide to endodontics – update part 1

“…Tsesis et al 17 compared a signifi cant increase in the results of a microsurgical approach versus conventional surgery, 91% compared to 44%. Microsurgery has been used in medical surgical procedures for some considerable time, so perhaps modern dentistry is just catching up with its medical colleagues.…”
