The aim of the study was to present the distribution of traumatic dental injuries in the permanent anterior teeth in 447 consecutively selected patients in the age interval of 6 to 25 years treated at the Department of Paediatric Dentistry at the University Dental Clinic in Rijeka, Croatia, in the period from 2001 to 2006. Data on age, gender, number of injured teeth and type of injury were taken from the dental records. Of all 447 consecutively selected patients with traumatic dental injury 56.2% were boys and 43.8% were girls with a male/female ratio 1.28:1 (P < 0.01). The highest frequency of tooth injuries occurred among 10- to 13-years-old children. Among 30.6% of the cases, two or more teeth were injured (38.6% in boys and 21.4% in girls). Traumatic injuries affecting teeth in the upper jaw were more frequent (P < 0.001). The most commonly affected teeth were the maxillary central incisors (42.4% of right central incisors and 38% of left central incisors). The most frequent injury was enamel and dentin fracture without pulpal involvement (38.7%). In conclusion, more attention should be paid to preventive measures.

The aim of this study was to evaluate Croatian undergraduate students' knowledge based on what they learned in the recent course, as well as the students' own judgment and opinions about geriatric dentistry education concerning temporomandibular disorders (TMDs) of the elderly. The study was carried out by means of a questionnaire administered in the last study year to students of the School of Dental Medicine, University of Zagreb and students of the Department of Dental Medicine at the School of Medicine, University of Rijeka. Th e questionnaire included questions about relevant specific knowledge on TMD, and statements related to their own opinion about geriatric dentistry education received during the study. Regarding students' knowledge related to TMDs, students from Rijeka gave more positive answers (p=0.012). Students from Rijeka gave more positive answers regarding physical therapy for treatment of TMD (p=0.004) and disc displacement and osteoarthritis as the most common disorders of the temporomandibular joint (p=0.031). Students from Zagreb were more unsatisfi ed with the skills in the field of geriatric dentistry (disagreed 57.45%) than students from Rijeka (45.83% had neutral standpoint and 37.50% agreed) (p=0.005). The level of the participants' knowledge pointed to the need of improving undergraduate dental teaching about the specific geriatric education, including knowledge about TMD.

Materijal i metode: U istraživanju su sudjelovala 32 potpuno ozubljena ispitanika (16 muškaraca i 16 žena). Inkluzijski kriteriji studije obuhvatili su asimptomatske ispitanike s normalnim okluzijskim odnosima (Angleova klasa I) u dobi od 20 do 33 godine (prosječna dob 22,6 ± 4,7 godina). Trodimenzionalni pomak kondila (anteroposteriorni, superoinferiorni i mediolateralni) između položaja centrične relacije (CR) i maksimalne interkuspidacije (MI) bio je analiziran upotrebom indikatora položaja mandibule (MPI, SAM Prazisionstechnik GmbH, München, Njemačka). Rezultati: Prosječni trodimenzionalni pomak kondila iznosio je 0,13 ± 0,12 milimetara za prijenos obraznim lukom i 0,22 ± 0,23 milimetra za prosječno montiranje. Nisu zabilježene statistički značajne razlike između spolova. Rezultati Mann-Whitneyjeva testa pokazali su statistički značajne razlike za anteroposteriorni i superoinferiorni pomak kondila (P < 0,001). Razlika u mediolateralnom pomaku nije bila statistički značajna. Zaključak: S obzirom na odstupanja unutar trodimenzionalnog pomaka kondila, prijenos obraznim lukom pokazao se točnijim u odnosu prema prosječnom montiranju u poluprilagodljivi artikulator. No prosječne vrijednosti trodimenzionalnog pomaka kondila nisu odstupale od normalnih vrijednosti, pa nemaju kliničko značenje. Prema tome, pouzdanima se mogu smatrati oba načina prijenosa (prijenos obraznim lukom i prosječno montiranje) kod asimptomatskih ispitanika s normalnom okluzijom.Ključne riječi artikulatori; centrična relacija; zglobna osovina; prijenos obraznim lukom 1 Dom zdravlja Zagreb zapad, Albaharijeva 5, 10000 ZagrebHealth center Zagreb west,
