Outcome of Surgical Endodontic Treatment Performed by a Modern Technique: A Meta-analysis of Literature

Unusual Endodontic Treatment: A Surprise

“…[1] The success of peri-radicular surgery is influenced by several factors, such as: surgical procedures using different materials, clinical and radiographic evaluation, systemic conditions, and local factors. [10] …”

Classifying scientific evidence as the basis for evidence-based decision making: is strength of evidence absolute?

“…Since the introduction of LOE, several other organizations have adopted various classification systems, most of which share a lot in common (Bossuyt & Leeflang 2008;Gutmann 2009;Mileman & van den Hout 2009;Reitsma et al 2009;Rosenberg & Donald 1995;Suebnukarn et al 2010;Sutherland & Matthews 2004;Zwahlen et al 2008;Burns et al 2011; Canadian Task Force on the Periodic Health 1979). To-date, classification systems such as the system presented by the "Oxford Centre for Evidence-Based Medicine" (Oxford Centre for Evidence-based Medicine -The Oxford 2011) attempt to provide comprehensive hierarchical grading for classifying scientific evidence (Bossuyt & Leeflang 2008;Gutmann 2009;Mileman & van den Hout 2009;Reitsma et al 2009;Rosenberg & Donald 1995;Suebnukarn et al 2010;Sutherland & Matthews 2004;Zwahlen et al 2008;Burns et al 2011; Canadian Task Force on the Periodic Health 1979; Tsesis et al 2009). …”

“…The traditional hierarchical systems of classifying the evidence primarily use the study design as the basis for the grading process (Bossuyt & Leeflang 2008;Gutmann 2009;Mileman & van den Hout 2009;Reitsma et al 2009;Rosenberg & Donald 1995;Suebnukarn et al 2010;Sutherland & Matthews 2004;Zwahlen et al 2008;Burns et al 2011; Canadian Task Force on the Periodic Health 1979; Tsesis et al 2009). A clinical study may be experimental (interventional) or observational.…”

“…These observations are done either by looking forward and gathering new data (prospective), or by collecting already existing data (retrospective studies) (Sutherland 2001). As an example of the levels of evidence, in practically all LOE classification systems Randomized controlled trials (RCTs) are considered as a high LOE, as opposed to Case reports and Case series that are considered as a low LOE (Bossuyt & Leeflang 2008;Gutmann 2009;Mileman & van den Hout 2009;Reitsma et al 2009;Rosenberg & Donald 1995;Suebnukarn et al 2010;Sutherland & Matthews 2004;Zwahlen et al 2008;Burns et al 2011; Canadian Task Force on the Periodic Health 1979; Sutherland 2001; Tsesis et al 2009). …”

Update of guidelines for surgical endodontics – the position after ten years

“…These report more consistent healing outcomes of between 88% and 96%. [7][8][9] This suggests that modern surgical endodontic techniques, including appropriate case selection, are associated with a high degree of success.…”
