St. János Hospital, Budapest, Hungary The magnitude of sialolithiasis, beside of its relatively high prevalence, reveals itself that the inflammation of the gland and the position of the sialolith together can lead to a partial or total excision of the gland. The avoidance of these stumper surgical interventions is important because after the operation on face or neck the patient can suffer from its severe aesthetic and functional consequences. The early recognition and gentle remove of sialoliths are parts of the recent con­servative therapy of sialolithiasis. The authors’ aim is to introduce the up-to-date therapeutical devices. MANIFESTATION OF ASCARIS LUMBRICOIDES INFECTION IN THE MAXILLOFACIAL REGION BERECZKEI, Á., KATONA, J. St. János Hospital, Budapest, Hungary In the daily dental routine there are a lot of patients complaining of swellings in the maxillofacial region. In the background mainly dental or otorhinolaryngeal dis­eases are detected. In this region swellings can also manifest due to dermatological problems. We can rarely recognize certain aspecific inflammatory diseases - for example parasitic ones. This case presentation is to introduce a general Ascaris infection. The patient with a facial swelling showed up in our department. He was over dermatological examination. First we were looking for dental or oral-surgical origins. It was first suspected as a salivary adenoma. We doubted this preliminary diagnosis, because in the region of canine fossa there can only be an ectopic salivary adenoma. After surgical excision some larvaceous mass was removed from the nodule. The further histological and parasitological examinations revealed an Ascaris infection. The im­portance of this case is that in the 35 years history of our department it was the only Ascaris infection with maxillofacial manifestation. COMPARISON OF THE PALATAL IMPLANT AND A CONVENTIONAL TOOTH-CONNECTED ANCHORAGE SYSTEM IN ADOLESCENTS BORSOS, G., VÉGH, A. Heim Pál Children’s Hospital, Department of Orofacial Orthopaedics and Orthodontics, Budapest, Hungary Introduction: The purpose of this study was to com­pare the palatal implant (PI) supported anchorage with a conventional intra-oral dental anchorage (DA) in ex­traction cases requiring maximum distal anchorage for the two-phase retraction of maxillary anterior teeth in adolescent patients. The Randomized Clinical Tri­al was previously approved by the Regional Research Ethic Commission (No.:236/2000). Material and methods: 18 adolescent patients (mean age 14.16 ±_1.6 years) were randomly allocated and treated with two maxillary first premolar extractions. In the PI group (n=9, mean age 13.7 ± 0.92 years) os­­seointegrated palatal implants (Orthosystem®) were placed in the midpalate, and in each case a 1.2 mm square stainless steel rigid transpalatal wire was fixed to the implant and to the molar bands by laser-weld­ing. In the DA group (n=9, mean age 14.3 ± 1.8 years) the conventional anchorage was provided by a 0.017 X 0.025 inch heat-treated SS utility arch that joined the upper first molars to the front teeth, and this was com­bined with a TPB. For the canine retraction (Phase I) super elastic closed-coil spring (150 cN) was used be­side a 0.016 X 0.022 inch SS segment arch to ensure torque control in both groups. Sequential activation of the ‘teardrop’ closing loop of the SS contraction arch was used for incisor ‘en mass’ retraction (Phase II). Duration of Phase I and Phase II were measured. Be­fore and after these main treatment phases the 6-PTV distances in both groups were noted on the lateral ce­­phalograms. Results: No significant difference was observed be­tween the groups regarding the duration of the ex­traction’s gap closure (p < 0.975) and the first molar position (p < 0.1) during Phase I. In the PI group, the duration of Phase II was shorter than in the DA group (p < 0.04), and in the meantime a significant me­­sialization of the first molars (p < 0.01) was also ob­served in the DA patients. The duration of the whole orthodontic treatment was 7.5 months shorter in the PI
