[Results of follow-up after apicoectomy with 2 different root canal filling materials].

Clinical and radiological findings in two groups of patients in whom apicectomies were done are presented. In one group root canal filling was by means of phosphate cementum; in the other, Diaket and guttapercha points were used. Evaluation was according to the methods applied already by Lüders in 1990. Preoperative diagnoses most often had been chronic periapical periodontitis followed by traumatic injuries to frontal teeth and complications encountered during endodontic treatment. In those persons in whom phosphate cementum had been applied, treatment was successful in 210 teeth (77.2%) and a failure was noted in 62 teeth (22.8%). In the Diaket/guttapercha group the success rate was 167 teeth (80.7%), while treatment was without success in 40 teeth (19.3%).

[Comparative studies with apicoectomy using various surgical techniques and filling materials].

Follow-up examinations were made retrospectively on 799 apicoectomized teeth from a group of patients with a total of 3,524 apicectomies, the mean postoperative interval of observation being 4.2 years. An intraoperatively orthograde root-canal filling was performed in 51.3%, an intraoperatively retrograde in 23.7% and a preoperative filling in 25.0% of the patients. Apart from 126 teeth that had already been extracted, a further 160 teeth had been clinically and/or radiologically conspicuous, so that a total of 286 failures was to be recorded. The dentally related success graphs computed according to Kaplan and Meier (1958) showed a significantly worse success probability for the preoperative filling compared to the two other techniques. With regard to the different materials employed in orthograde application, the silver filling had a higher and the guttapercha filling a less favourable success quota compared to a titanium filling. Moreover, in the retrograde method, amalgam resulted in a significantly higher success probability than glass ionomer cement. With an attendant cyst there was a significantly improved success quota over apical parodontitis or a renewed operation. With regard to the localization of apicectomies, maxillary front teeth attained the highest success rate. The present results point unequivocally to an unfavourable outcome after preoperative endodontics and underscore the good prognosis of an intraoperatively orthograde filling. Due to the fact that biocompatibility is in the forefront today, time-tested materials, such as silver and amalgam, are clearly being used less.

[Periodontal function and oral hygiene following an operation for apicoectomy].

The author analyzes the effect of the dental root apex resection on the function of marginal periodontal tissues of the operated on tooth and oral hygiene of 103 patients with chronic periapical foci of odontogenic infection, aged 12 to 53, on the basis of the data of monitoring the changes in the content of gingival fluid, depth of the gingival grooves or pouches, and the Schiller-Pisarev test and hygiene index. The operation in question was found to essentially disorder the biologic equilibrium in the marginal periodontal tissues and to deteriorate the hygienic status of the oral cavity. The developing shifts are reversible and disappear in two weeks after surgery. The author emphasizes that such patients should be timely trained to take care of the oral cavity in order to improve its hygienic status in the postoperative period.

The use of tricure glass ionomer cement as an apical sealant after apicoectomy.

The adaptation and sealing ability of a tricure glass ionomer material (Vitremer), used in a retrograde cavity was assessed and compared with amalgam. Fifty single-rooted, extracted teeth were prepared and filled endodontically. All teeth underwent root resection and retrograde cavities were prepared. The teeth were divided into two groups. One group of 10 teeth received a layer of varnish and an amalgam filling in a retrograde cavity, while the other group of 40 teeth received a layer of primer and a glass ionomer filling. All the teeth were placed in an aqueous solution of Procion Brilliant Blue for 7 days whereafter ground sections were prepared. Micro leakage was determined according to the extend of dye penetration using an image analysis system. The results showed that significantly less dye penetration was observed in teeth filled with the glass ionomer cement than in those with the amalgam.

[Dens in dente: apicoectomy and retrograde obturation].

Dens in dente is a developmental anomaly, which, in some advanced cases, requires a combination of conventional and surgical endodontic treatment. The purpose of this article is to suggest how to treat a Type 3 (Oehlers classification) dens in dente.

Apicoectomy of an endosseous implant to relieve paresthesia: a case report.

Various radiographic and surgical techniques have been recommended to avoid paresthesia following mandibular implant placement. However, nerve impingement is sometimes inevitable, and when lingering numbness is reported, clinicians have a limited number of corrective options. This report describes a technique for cutting-back the apex of the implant, a technique that may be useful when lingering numbness persists after osseointegration has occurred.

Clinical and radiological course in apicoectomies with the Erbium:YAG laser.

OBJECTIVE: A study is made of the efficacy of the Erbium:YAG laser in granulomatous periapical lesions, based on clinical and radiographic controls. MATERIAL AND METHODS: The study comprised a series of 45 patients amenable to periapical surgical treatment of incisors, canines and premolars. A conventional surgical technique was used, with silver amalgam retrograde filling and irradiation of the bone defect and remnant root cement with the Erbium:YAG laser. Clinical and radiographic controls were made during 24 months, assessing the absence of symptoms and the presence of pain, swelling or fistula and ossification of the lesions, respectively. RESULTS: The clinical course proved asymptomatic in 95.5% of the cases. As regards remodeling of the bone cavity, 77.7% had completed ossification after 24 months, 13.3% were in an advanced stage of ossification and 4.5% in an intermediate stage, while 4.5% showed treatment failure. CONCLUSIONS: The combination of silver amalgam and irradiation with the Erbium:YAG laser in periapical surgery showed a very high clinical success rate, with a 77.7% bone cavity remodeling rate after 24 months.

Long-term, postsurgical results on teeth with periapical radiolucencies.

Reported high failure rates of endodontic surgical procedures seemed to be inconsistent with the clinical impression of a high success rate. A retrospective study of endodontic surgical cases treated longer than 10 yr ago was done to look at long-term results. Forty-one teeth in 39 patients were able to be evaluated. These teeth had either an apicoectomy, an apicoectomy with a root-end amalgam, or in two cases, a root amputation. Of the 23 teeth that had an apicoectomy, 19 (82.6%) completely healed. Of the 16 teeth that had an apicoectomy followed by a root-end amalgam, 10 (62.5%) completely healed. Surgical endodontic procedures performed before the use of magnification, newer root-end filling materials, and ultrasonics, still had a high rate of success.
