The purpose of this study is to evaluate the efficacy of using endodontic H-files luted with Resin modified glass ionomer cement (RMGIC) in removing fractured palatal root.
This study consists of 30 patients, of which 16 were males and 14 were females with a mean age of 36 years. In which, 19 were maxillary first molar and 11 were maxillary second molar. In that, 18 were fractured at the level of apical 1/3(rd) and 12 were at the level of apical 2/3(rd). All cases were first tried with endodontic H-files, within few attempts, it was wedged tightly in the remaining pulp chamber with one or two clockwise direction and using sudden jerk with a downward pull the remnant part was removed. The cases, which fail to deliver after several attempts were taken up for study. After sufficient isolation with a rubber dam and the socket was dried using sterile gauze, under good lighting and vision again the same file was introduced, which was now luted with RMGIC, after 5 min of setting time, the same attempt using sudden jerk with a downward pull was given.
In those 30 cases, 20 cases were removed in the first few attempts using endodontic H-files. The 10 cases (7 cases were apical 2/3(rd) and 3 cases were of apical 1/3(rd)), which fails to come out were tried using endodontic H-files luted with RMGIC, in which 9 cases were successfully removed (90%) and 1 case of apical 1/3(rd) was again failed to come out.
Even though, the number of cases were too small to come to a definitive conclusion, the encouraging result (90%) and technically easy, this is a novel method of removing fractured palatal root atraumatically and devoid of any complication.
本研究旨在评估使用树脂改性玻璃离子水门汀(RMGIC)粘结的根管H锉去除腭侧根折的疗效。
本研究包括30例患者,其中男性16例,女性14例,平均年龄36岁。其中,上颌第一磨牙19例,上颌第二磨牙11例。其中,18例在根尖1/3处折断,12例在根尖2/3处折断。所有病例首先尝试使用根管H锉,在几次尝试后,将其沿顺时针方向一或两圈紧紧楔入剩余的髓腔,并突然向下拉动使其折断,将剩余部分取出。经过几次尝试仍无法取出的病例纳入研究。用橡皮障充分隔离后,用无菌纱布擦干牙槽窝,在良好的照明和视野下再次插入同一根锉,此时该锉已用RMGIC粘结,凝固5分钟后,再次突然向下拉动进行同样的操作。
在这30例病例中,20例在最初几次尝试中使用根管H锉取出。10例(7例根尖2/3折断,3例根尖1/3折断)未能取出的病例尝试使用用RMGIC粘结的根管H锉,其中9例成功取出(90%),1例根尖
