Il presente studio effettuato sulla popolazione italiana bianca caucasica di 14 anni ha evidenziato che la forma d’arcata più frequentemente rilevata è la ovale, sia a livello mascellare che mandibolare. La seconda forma per frequenza è la conica soprattutto a livello superiore. La forma meno frequente è la quadrata.
L’arcata superiore presenta valori millimetrici maggiori rispetto all’inferiore e per questo è più grande. Tra le forme d’arcata la conica è quella mediamente più grande, l’ovale la minore.
I maschi presentano arcate più grandi delle femmine ed hanno forma mascellare conica ed ovale in eguale percentuale, le femmine ovale. L’arcata inferiore nei maschi è di poco maggiormente conica rispetto alla forma ovale, nelle femmine è ovale.
Le ratio molari (RM) tra forme d’arcata diverse, sesso e tipo di arcata hanno valori simili.
Le ratio canine (RC) invece variano molto risultando maggiori nella forma d’arcata quadrata e minori nella conica, maggiori nelle femmine rispetto ai maschi, maggiori nell’arcata mandibolare.

Ringraziamenti
Desidero in primis ringraziare mia madre per la fiducia che ha sempre dimostrato di avere in me e per gli anni di sacrifici passati assieme.
Ringrazio la Professoressa Maria Rita Giuca per avermi insegnato il codice di comportamento che un medico deve avere nel portare rispetto agli altri e soprattutto a se stesso.
Voglio salutare i miei compagni di corso con i quali sono cresciuto durante questi sei anni che ci hanno trasportato nel divenire, da ragazzi appena usciti dal liceo, persone adulte sotto un punto di vista professionale ed etico.
Per l'amicizia che mi lega a tutti loro e che durerà nel futuro.
Ringrazio infine i miei amici, quelli veri.
Che possa la persona che son diventato essere al loro servizio sempre.
