Retrospective Evaluation of Perforation Repairs in 6 Private Practices

Clinical and Radiographic Evaluation of the Healing after MTA Application on Mechanical Furcal Perforations in Primary Molars-part2

“…Total evaluation with different sizes refers to a result with no statistical important-difference (p-value>0.05) but this difference was clinically important. This result agree with what Pontius et al had found in their retrospective study at 2013 on perforations that had been treated by a number of specialists, and said that the larger sized-perforations had decreased the success rate of the treatment [19].…”

“…We didn't detect the size of the perforation in millimeter in our inclusion criteria because of the differences in type and size of the treated teeth, so we had to estimate the perforation size according to the tooth size, and we considered the whole destruction of the floor of the pulp chamber or the presence of more than one perforation in the floor a large sized-perforation, and except that a small sizedperforation. Criteria of perforation size-assessment in permanent teeth have differed between authors [15,19,25,65], also in primary teeth in-vitro studies were conducted on artificial perforations with different sizes (0.5 and 1 and 2 mm) [5,29,45] and they were uniform at every study and there was no comparison between two sizes or more than that. Total evaluation with different sizes refers to a result with no statistical important-difference (p-value>0.05) but this difference was clinically important.…”

“…The prognosis of the perforations depends on the capability to repair them and preventing bacterial contamination [15][16]. Numerous factors affects the ability on infection control in perforation site subsequently the material capacity on sealing the lesion, those factors include time from occurrence to repairing, size, shape, location, repairing material [5,8,11,15,17,18], patient's sex and age [19,20], tooth position in the mouth (upper/lower) [21], experiences of the clinicians [22] and the presence of lesion and/or direct communication between the perforation site and the oral cavity before the treatment [23]. The best time to repair perforations is immediately after occurrence [7,8,15,24] according to some authors who said that time is the most important factor to expect the treatment outcomes [15].…”

Mineral trioxide aggregate and other bioactive endodontic cements: an updated overview – part II: other clinical applications and complications

“…The location of the perforation and the quality of the final restoration had a significant influence on the outcome of perforation repair (Pontius et al . ), whilst the site of perforation (mid‐root and apical) and perforation size larger than 3 mm were reported as significant predictors for the recurrence of progressive inflammation following initial healing (Gorni et al . ).…”

The effects of various mixing solutions on the biocompatibility of mineral trioxide aggregate

“…In endodontics, mineral trioxide aggregate (MTA) is widely accepted as the gold standard cement for a broad spectrum of clinical applications including direct pulp capping (Bogen et al 2008, Accorinte et al 2009, Mente et al 2010, pulpotomy (Lin et al 2014), apexification (Mente et al 2013), root perforation repair (Pontius et al 2013), internal or external root resorption restoration (Ebeleseder & Kqiku 2015), root canal filling (Prati & Gandolfi 2015) and apical surgery (Chong et al 2003, Saunders 2008, von Arx et al 2014.…”
