Adresa za dopisivanje Dr. Joycelyn Eigbobo College of Health Sciences, University Of Port Harcourt Department of Child Dental Health, 500001 Port Harcourt, Nigeria [email protected] Sažetak Svrha: Željelo se dobiti odontometrijske podatke u trima dimenzijama – meziodisalnoj i bukolingvalnoj širini, te visini kliničke krune u mliječnoj denticiji kod nigerijske djece. Materijali i metode: Uzorak se sastojao od 400 zdrave djece u dobi od tri do pet godina kojoj su niknuli svi mliječni zubi. Nasumce su bila odabrana iz šest javnih vrtića. Nakon toga su od odabranog uzorka od alginatnih otisaka izrađeni gipsani modeli. Pomičnom elektroničkom mjerkom obavljena su i mjerenja meziodistalne (MD) i vestibularne (VO) širine te vrijednosti visine kliničke krune (VKK). Deskriptivna statistika dobivena je unosom vrijednosti u program SPSS verzija 13. Rezultati: Izmjereno je ukupno osam tisuća zuba. Aritmetička sredina vrijednosti MD-a i VO-a povećavala se progresivno od bočnih sjekutića do drugoga mliječnog kutnjaka u maksilarnom luku, a kod mandibule rasla je od središnjeg sjekutića do drugoga mliječnog kutnjaka. Najveća aritmetička sredina širine MD-a od 10,20mm+0,56 pronađena je na drugom mandibularnom kutnjaku, a drugi maksilarni kutnjak imao je najveću aritmetičku srednju vrijednost BL-a 9,74mm+0,58. Kod mandibularnog očnjaka zabilježena je najveća vrijednost VKK-a – iznosila je od 5,83mm+0,61. Dječaci su kod većine zuba imali veću aritmetičku sredinu. Ustanovljena je statistički značajna razlika među visinama zuba obaju spolova (p<0,05) te varijanca unutar njihovih vrsta. Zaključak: Može se reći da djeca u Nigeriji imaju veće mliječne zube negoli bijelci te Arapi (Jordanci) i Kinezi (Tajvanci), a istodobno su manji od zuba australskih Aboriđina. Zabilježena je i sličnost u dimenzijama s djecom u Indiji.
