Results: The means of the angle of each group were categorised and compared according to dental status, age, sex, and side. The highest values were measured in Group I (right side: 39,8±5,4°, left side: 43,0±5,9°), values were already lower in Group II (right side: 38,9±4,7°, left side: 39,5±7,4°), and mean values turned out to be the lowest in Group III (right side: 29,8±6,0°, leftside: 31,9±5,2°). The correlation coefficient between age and the rate of decrease of the posterior slope of the articular eminence in Group I, II and III were 0.23, 0.35 and 0.92, respectively. The calculated values were examined by Students’ two-sample t-test and single factor variance analysis as well. No significant difference has been found between Group I and II, but Group III differed significantly from both Group I and Group II There was no significant difference between the right and the left side, neither between males and females. Conclusion: According to the data obtained, we have arrived to the conclusion that the flattening of the articular eminence is partly due to old age, however the rate of deformation is significantly higher in total edentulous patients than in patients with maintained occlusion. HUNGARIAN CEPHALOMETRIC VALUES COMPARED WITH RICKETTS’S NORMS CSÍKI, I., VÉGH, A Heim Pál Children’s Hospital, Department of Orofacial Orthopaedics and Orthodontics, Budapest, Hungary Aim of investigation: The aim of this study was to define cephalometric norms specific to Hungarian adolescents with malocclusion, and to compare these with Ricketts’s cephalometric standards. Subjects and methods: The study was carried out using digitalised lateral cephalograms of 500 adolescents diagnosed with malocclusion (238 males and 262 females; mean age: 15y1m; SD: 1y8m), without receiving any previous orthodontic treatment. The computer-aided cephalometric analysis was performed using Ricketts’s method. From 30 variables (angles and lengths) obtained the next five measurements were statistically analysed (SPSS 5.0 for Windows): craniofacial deflexion, facial convexity, facial axis angle, mandibular angle and conical angle. Results: Cranio-facial deflection angle showed a range of variation between 16.5° and 36.2°, having a mean of 27.66 ± 3.63°. Range of facial convexity was 21.4 mm (from -10.7 to 10.7mm) with a mean value of 0.8±3.2 mm. Facial axis angle height presented a minimum of 76.1° and a maximum of 101.5° with a mean of 89.4+4.6°. Mandibular angle resulted from the range of 4.3° minimal to 53.7° maximal values, presenting a mean of 20.5+7.5°. Measurements for conical angle showed a 71.78° mean, with a range of 84.6. Conclusions: In spite of diagnosed malocclusion and need of treatment, a high coincidence of measured values was found when compared to the normative data established by Ricketts. SOME ASPECTS OF EXISTENTIAL PSYCHOTHERAPY IN DENTISTRY FÁBIÁN, T.K.1, KOVÁCS, SZ.1, MÜLLER, O.2, FÁBIÁN, G.2, MARTEN, A.2, FEJÉRDY, P.1 1Clinic of Prosthetic Dentistry, Semmelweis University, Budapest; 2Clinic of Pediatric Dentistry and Orthodontics, Semmelweis University, Budapest, Hungary Existential psychotherapy suppose four basic conflicts as causes of psychopathological processes such as: transitoriness (mortal nature, death); liberty (liability, will); insulation (existential aloneness); and meaninglessness (meaninglessness of life). Based on clinical experience and theoretical considerations, authors hypothesize that these four basic conflicts may play an important role in the development of psychogenic dental problems such as dental fear, odontophobia, and several oro-facial psychosomatic manifestations as well. Especially the conflict of transitoriness (mortal nature, death) seems to be highly important. Tooth loss (especially edentulousness) symbolizes the loss of living force, and evokes a symbolic meaning of growing old, evanescence and death. Another important coupling of mouth and teeth to the conflict of transitoriness is rooted in the early phase of psychological development. The early experience of the infant related to losing somebody (the baby must be taken off the breast) and destroying something (intake of food with the use of the teeth) is strongly coupled to the oral region during the so-called oral-sadistic stage of the psychological development. Authors conclude on that, further rese arch should be carried out to clearly demonstrate the influence of the above-mentioned main conflicts on the psychogenic dental problems.
