[The use of composite materials for the orthodontic treatment of patients with the vertical form of pathological tooth abrasiveness].

The author summarizes his experience with 34 patients with localized vertical pathological teeth abrasion. The coronal defects of 189 anterior teeth were corrected using individually fitted polymeric caps and composition materials: carbodent and epacryl (USSR), evicrol (CSSR), microrest (Japan). The technique is described in detail with its advantages, indications and contraindications.

Quality evaluation of anterior restorations in private practice.

As part of a series of postgraduate courses in Cariology for dentists, a section designed to stimulate the interest in quality evaluation of fillings was included. Thus, 75 private practitioners were asked to evaluate a number of anterior restorations on their own patients. The method used was a modification of the California Dental Association (CDA) quality evaluation system. By use of a four-graded scale the following five properties were evaluated: (1) color of the filling, (2) color of the margin, (3) surface structure and anatomic form, (4) marginal integrity, and (5) caries. The criteria were related to practical-clinical measurements. Altogether 1147 fillings were assessed, most of them 2-4 years old (n = 949). The results showed that 25 different brands had been used, of which 4 composites constituted 68% of all fillings. With the exception for one composite material, no obvious difference in the quality evaluation between the materials was observed. Of the 2-4 year old fillings, approximately every fourth was rated as "not acceptable", i.e. with need for clinical treatment "soon" or "within reasonable time". Our impression was that the system used in this study is suitable for an assessment of the quality of anterior fillings in a private practice and that it should stimulate dentists to a quality thinking in dentistry in general.

Conservative technique for restoring primary molars after pulpotomy treatment.

The conservative technique provides a more esthetically pleasing result in patients where significant tooth structure remains after completion of a pulpotomy. This technique is particularly beneficial for situations where the access for the pulpotomy was made through only the occlusal surface, leaving all proximal surfaces intact.

The improvement of technical skills in preclinical courses.

One hundred fifty-four freshmen dental students were administered a fine motor ability test prior to and at the completion of a series of preclinical technique courses. The pre- and posttest performances were compared for each student to determine whether an improvement of technical skill had occurred. The pre- and posttests were also graded using the rank ordered method. The number of students who demonstrated improvement in technical skill was compared to the number of students who improved in grades to establish whether the change in grades was indicative of the observed change in technical skill. Most students improved in technical skill; however, grades did not reflect this improvement.
