Sažetak
Introduction: Mandibular incisor crowding can occur during and at the end of adolescence when it is referred to as late crowding. The aetiology is still unclear, although several theories are proposed. Growth and development of facial bones continue throughout adolescence and some growth patterns may be associated with the occurrence of late crowding. Objective: To assess the relation between late mandibular crowding and facial growth. Materials and Methods: The sample consisted of 62 orthodontically untreated subjects(50% female), recalled for check-up every three years, from the Nittedal growth study, Norway. The Little index, a measure of amount of crowding, was assessed on subjects` plaster casts at the age of 12 and 21. Intermaxillary angle and length of the mandibular base were measured on latero-lateral cephalograms at the age of 12 and 21. Results: A significant decrease in the intermaxillary angle was observed (p<0.001). Although the decrease was significant in both genders, higher was observed in males (28.9 vs. 25.9) than in females (28.7 vs 27.0). The base of the mandible grew in length significantly during adolescence (p<0.001). Incisor crowding increased significantly at the age of 21(p<0.001). No linear correlation was found between the amount of increase in crowding and amount of decrease in the intermaxillary angle nor increase in mandibular length. Conclusion: Decrease of divergence between maxilla and mandible, lengthening of the mandibular base and late mandibular incisor crowding do occur during adolescence, however, great individual variability is present sothe relationship cannot be characterized as linear.
