Atypical courses of the mandibular canal: comparative examination of dry mandibles and x-rays.

Knowledge of the course of the mandibular canal and its anatomic variations is of great importance in oral surgery, especially in preprosthetic operations and the insertion of endosteal implants and during the planning of removable dentures prepared in cases involving extensively atrophied mandibles. We review the literature on duplicated mandibular canals, which is based exclusively on radiologic findings. Then, we compare this with an examination of dry mandibles and further radiologic studies. The incidence of duplicated mandibular canals observed in macroscopic examinations of mandibles was substantially higher than that revealed by radiographs. One case involving a novel variation, a triple mandibular canal, is reported.

[The clinical importance of the mandibular canal course variations].

The authors review the literature relating to anatomical variations of mandibular canals. They compare the results of their examinations with the literature data. The proportion of duplicated mandibular canal observed during macroscopic examinations of mandibles proved to be substantially higher than that revealed by X-ray pictures. The knowledge of the course of the mandibular canal and its anatomical variations is of great importance in certain oral surgical interventions, such as preprosthetic operations and the insertion of enosseal implants, and during the planning of removable dentures prepared in cases involving extensively atrophied mandibles. The authors review the possible consequences of the injury of accessory mandibular canal.

[Factors impeding obstructed teeth in their eruption. Case report].

With preparation of six study cases the objective of the authors was to abrow colleagues' attention to the fact that teeth remained in impactio and retention might cause complaints not only due to normal anatomical reasons but some complications might occur resulting from anomaly of development. The authors consider the topic extremely important by reason of the case's varieties and the clinical observations made recently and frequently. An increased attention to this case is reasonable since eruption of teeth might happen in case of removal of obstructic fact in time, permanent row of teeth returns to normal, and adequate dental arch might develop. It is also obvious that medical treatment of impact abnormalities derived from anomaly has lack of exact therapy theories, only general protocol can be provided.

Antimicrobial efficacy of various root canal preparation techniques: an in vitro comparative study.

In this study, we compared the antimicrobial efficacy of various root canal preparation techniques and instruments in the root canals of 40 human first maxillary premolars extracted for orthodontic reasons. After extirpation of the pulp, teeth were sterilized in an autoclave. Then, the root canals were infected with Enterococcus faecalis suspension and the teeth incubated at 37 degrees C for 24 h. Thereafter, the teeth were divided into five groups: preparation with K-file or K-Nitiflex file (step-back technique; groups 1 and 2), K-reamer (standardization technique; group 3), irrigation only (group 4), and no treatment (group 5). Before and after treatments, samples were taken for culture. Results were evaluated after 24-h incubation in E67 selective culture medium. We observed a considerable reduction in bacterial population after mechanical preparation. No significant differences were seen among the efficacy of the various preparation techniques and files used.

[Gardner syndrome. Case reports].

The authors discuss 3 cases of Gardner-syndrome, outlining malignized large intestine polyposis, multiplex osteomas and the different skin tumours as the main features. The earliest symptoms suspecting the clinical picture are usually dental and/or mandibular lesions and draw the attention to the highly malignant polyposis.
