A MINIMAL-IVASIVE POSSIBILITY IN THE TREATMENT OF SEVERAL IDIOPATHIC SYMPTOMS OF DENTURE INTOLERANCE Introduction: Idiopathic symptom is a collective noun of complaints of unknown origin. In such cases no significant somatic data were found to establish a diagnosis, and psychotherapy also proves to be uneffective to reduce symptom perfectly. To treat such symptoms the use of combination of somatic, psychotherapeutic and physiotherapeutic methods is suggested. As a physiotherapeutic method, low induction value pulsed electromagnetic field stimulation was found effective in the treatment of vegetative neurosis, and several kinds of idiopathic pain symptom. However there is no data in the literature about the effectivity of this method in the treatment of certain symptoms of denture intolerance patients. Materials and methods: Authors investigated the effectivity of low induction value pulsed electromagnetic stimulation (induction value ranged 1pT-100AT; frequency ranged 1-2Hz-3000Hz) in the treatment of idiopathic symptom of denture intolerance patients. The use of magnetic field stimulation was combined with somatic and psychotherapeutic methods as well. The evaluation of its effectivity was based on personal opinion of patient and dentist as well as on visual analogue scale. Results: The method was introduced during the last months in the treatment schedule of denture intolerance patients of our clinic. The early experiences and impressions based on the treatment of our first patients are presented. Since there is no data in the Hungarian literature about this technique related to dentistry, several basic research data and clinical aspects are also discussed. DR. L. FEJÉRDY, DR. K. KALOCSAI, DR.

FEJÉRDY Semmelweis University, Faculty of Dentistry, Department of Prosthodontics, Budapest MONITORING TRENDS IN FIXED PARTIAL DENTURE DESIGNS BASED ON A NATIONAL SURVEY Introduction: In order to restore partially edentulous arches reasonable number of fixed partial dentures are designed in Hungary. This presentation aims to show statistical features of these restorations based on data from a large number of samples. Material and methods: Calibrated dentists of the Department of Prosthodontics performed oral health surveys according to WHO criteria. "First” survey was conducted between 1985 and 1989, “second” in 2003-2004. Subjects were interviewed and clinically examined using artificial light source, plane mouth mirrors, dental probes. After formal consent 4606 individuals, originally referred to perform x-ray lung screening examination, were enrolled in the nation-wide study. Representative sample sites from all regions of the country were selected, the patient sample comprised the population of the capital city, large towns and the rural areas. In the “first” survey data collected on 6224 FPD from 2879 participants; in the “second” survey data collected on 3676 FPD - 1460 lower and 2216 upper jaw restorations - from 1876 participants were analyzed. Besides time parameters, records were kept of number of pontic teeth, abutment teeth to pontic teeth ratio (abutment saturation), position of pontic teeth in the arch, position of abutment teeth in the arch, main features of “tooth location” adjacent to restoration (remnant tooth, crown, artificial tooth, missing tooth). Data were interpreted by SPSS 10.0.5 for Windows and statistical analysis was performed usinq two-way ANOVA. Results: Mean survival time was 9.34 years; scatter ± 8.47; median survival time 7.01; with the maximum of 47 years. Average number of FPD unit was: 6.34 for the maxillary and 4.62 for the mandibular jaw. Average number of abutment teeth: 3.58 maxillary and 2.82 mandibular teeth. Abutment saturation was: 0.76 considering the upper jaw and 0.74 for the lower jaw. Maxillary abutment teeth: canines (23%) most frequent and central incisors (19%); mandibular abutment teeth: canines (20%) most frequent, first premolars (19%) and second premolars (18%). In order of frequency: pontics of the upper jaw replaced first premolars (27%) and second premolars (23%); lawer jaw pontics replaced first molars (36%) and second premolars (21%). Conclusions: Findings of our survey demonstrated that results were much determined by the type of jaw, while the person’s sex and age influenced the outcome less. Comparison between left and right side of the arch revealed considerable symmetry. Recently collected data of 2004 show increased extension of fixed bridges with significantly higher number of abutment teeth involved. Statistical analysis of data collected on features of fixed partial dentures provide a sound basis for estimating the present oral health status of the population. Monitoring patterns of changes have also an important epidemiological relevance. Results of our present findings serve as a reliable source for planning future actions required to meet treatment needs and measuring efficiency of dental education. DR. P. FEJÉRDY, DR. K. NEMES, DR.

MADLÉNA Semmelweis University, Faculty of Dentistry, Department of Prosthodontics, Budapest PARTIALLY EDENTULOUS ARCHES, PARTIAL DENTURE DESIGNS - MONITORING CHANGES BETWEEN 1986 AND 2004 Introduction: Removable partial dentures are designed for the restoration of Class 2A, 2B, 2A/1, and Class 3 type partially edentulous arches. This presentation considers the effect of prostheses on remaining teeth and gives an overview of denture design based on data from a large number of samples.
