Abstract:
INTRODUCTION:The incidence of congenital hypodontia is increasing in daily practice. Early diagnosis of this dental disorder and the associated skeletal malocclusions is crucial for successful and stable final rehabilitation. AIM:Comparison of cephalometric findings of patients with hypodontia of 1-4 teeth with the measurement results of the control group without teeth agenesis. MATERIAL AND METHOD:We evaluated the lateral X-ray of 41 patients with 1-4 teeth agenesis selected from patients referred for orthodontic treatment to the Orthodontic Department of the University of Medicine and Pharmacy from Târgu Mureş within a two-year period. The results were compared with the values of the age and sex matched control group. RESULTS:Bilateral upper incisor and lower bicuspid were missing in most of the hypodontia cases. When looking at the NSGn angle predicting the growth direction of the mandible, statistically significant differences were found between the male (p = 0.012), the front (p = 0.010) and the hypodontia group (p = 0.024) and the control group. Regarding the ANB angle, which shows the sagittal position of the maxilla to the mandible, statistically significant differences were found between the subgroups (women, men, anterior or posterior hypodontia) and the control group. CONCLUSION:Larger number of skeletal class 3 and vertical hypodivergent tendency were observed in the hypodontia group. Orv Hetil. 2019; 160(6): 214-219. :Absztrakt: Bevezetés: A veleszületett csírahiány előfordulásának gyakorisága növekvő tendenciát mutat a mindennapi gyakorlatban. Az említett rendellenesség korai kórisméje ugyanúgy, mint a társult skeletalis eltéréseké, rendkívül fontos a sikeres és stabil végleges rehabilitáció tekintetében. Célkitűzés: 1–4 fogcsíra hiányában szenvedő páciensek kefalometriás leleteinek összehasonlítása a csírahiányban nem szenvedő kontrollcsoport mérési eredményeivel. Anyag és módszer: A Marosvásárhelyi Orvosi és Gyógyszerészeti Egyetem Fogszabályozás Tanszékének kétéves beteganyagából kiválasztott 41, csírahiányos páciens oldalirányú távröntgenjét értékeltük ki. Az így kapott eredményeket összehasonlítottuk a nem és életkor szerint hozzájuk rendelt kontrollcsoport értékeivel. Eredmények: A leggyakrabban kétoldali felső metsző és kétoldali alsó kisőrlő csírahiányával találkoztunk. A mandibula növekedési irányát előre jelző NSGn-szög vizsgálatakor statisztikailag szignifikáns eltéréseket találtunk a férfi (p = 0,012), az elülső (p = 0,010), illetve az oldalsó csírahiányosok (p = 0,024) csoportja és a kontrollcsoport között. A két állcsont egymáshoz viszonyított sagittalis helyzetét jelző ANB-szög vizsgálatakor statisztikai szempontból jelentős eltéréseket találtunk a nemek és a csírahiány fogíven belüli elhelyezkedése szerint elkülönített vizsgálati alcsoportok, illetve a kontrollcsoport között. Következtetés: A csírahiányos egyének skeletalis kefalometriás értékeit összevetve a nem és életkor szerint hozzájuk rendelt kontrollcsoport értékeivel, szignifikánsan több skeletalis 3. osztályt és a két állcsont síkja által bezárt szög hipodivergenciáját találtuk a csírahiányos csoportban.
