Outcomes of periradicular surgery in cases with apical pathosis and untreated canals

Molar apicectomy with amalgam root-end filling: results of a prospective study in two district general hospitals

“…Such studies have inferred furthermore that lack of good RCT compromises (or is likely to compromise) the outcome. 54,58,59 We were able to confirm this latter conclusion in the case of 20 teeth where RCT was absent throughout the study period and where in all instances periradicular rarefaction supervened, involving the periapex alone in the majority (Table 10).…”

Cirurgia parendodôntica com obturação simultânea dos canais radiculares: relato de caso clínico

“…Nos casos em que isso não ocorre e existe a persistência da exsudação no canal radicular, impedindo a obturação, o hidróxido de cálcio também deve ser utilizado, para que se obtenha a desinfecção dos canais radiculares, proporcionando um resultado satisfatório após a cirurgia parendodôntica complementar. 16 No caso relatado, houve dificuldade em debelar a infecção, pois a área comprometida era extensa e, mesmo utilizando-se medicação intracanal e sistêmica, não houve o resultado esperado. Sendo assim, optou-se pela realização da obturação do canal radicular simultânea ao ato cirúrgico.…”

A prospective, randomized, comparative clinical study of resin composite and glass ionomer cement for retrograde root filling

“…Differences between the success and failure rates with RP and CS was analyzed by c 2 test. Baseline material 67 100 89 100 67 100 89 100 134 100 178 100 Root fracture 1 1 1 1 2 3 2 2 3 2 3 2 Patient could not be located 3 4 5 6 0 0 0 0 3 3 5 3 Inconclusive radiographs 3 4 6 7 3 4 6 7 6 7 12 7 Final material 60 90 77 87 62 93 81 91 122 91 158 89 Several factors have been suggested to influence the prognosis of a retrograde root filling: periodontal status [13,27,33], quality of the conventional endodontic treatment [7,13,17], tooth type [19,29], size of the periapical radiolucency [13,19,21,27], clinical symptoms [16], and quality of the coronal restoration [2]. In our material there were no significant differences between the two groups on any of the parameters recorded before surgery.…”
