instrument breakage during treatment can lead to serious complications and carries the risk of treatment failure. when a file breaks in the canal, bypassing or removal can be difficult and the long-term prognosis of the tooth may be compromised. sometimes surgery may be indicated for removal of the broken segment. often some part of the root cannot be cleaned because of blockage by the broken f...

the developmental abnormality of tooth resulting from the infolding of enamel/dentin into the root is called dens invaginatus. management of such cases is usually challenging due to the morphological complexity of root canal system. this report presents a rare treatment protocol of a clinical case of oehler’s type iii dens invaginatus combined with an endodontic lesion in a vital maxillary late...

Due to the potential fatal complications in combination with the often very uncertain clinical and radiological signs and appearance the diagnosis is a challenge [2,6,7]. Even a biopsy or simple tooth extraction can result in a lethal haemorrhage [5]. In the literature several different treatment options like radical or conservative surgery or embolization (in combination or without) of are des...

introduction: in apical surgery, after apicoectomy and retro-preparation of canal, a retrofil material is applied to seal the apical region of the root canal. mineral trioxide aggregate (mta) is the gold standard material for this purpose. changing water/powder ratios of mta affects its properties. the purpose of this in vitro study was to determine the effect of liquid/powder ratio of retrofil...

Ventriculograms made 9-15 months after surgery in 48 patients with normal preoperative apical contraction were reviewed to determine the influence of apical venting on apical wall motion in patients undergoing coronary bypass surgery. After interpretation of postoperative apical wall motion, the patients were subdivided into two groups. One group consisted of 34 patients who were vented by inse...

OBJECTIVE To share our first experience with laparoscopic pectopexy, a new technique for apical prolapse surgery, and to evaluate the feasibility of this technique. MATERIALS AND METHODS Seven patients with apical prolapse underwent surgery with laparoscopic pectopexy. The lateral parts of the iliopectineal ligament were used for a bilateral mesh fixation of the descended structures. The medi...
