ABSTRACT
Objective: To determine the orthodontic treatment need in Egyptian school children living in Beni-Suef Governate.
Subjects and methods: The sample included three hundred and ninety-six participants aged between 9 and 15 years (189 males, 207 females) that followed the inclusion criteria of the study. The children were assessed to determine their need for orthodontic treatment using the dental health component (DHC) and aesthetic component (AC) of IOTN (index of treatment need).
Results: Considering the total sample, 27.3% and 17.2% showed definite need for orthodontic treatment according to DHC and AC of IOTN respectively. There was no statistically significant difference between males and females in orthodontic treatment needs except in moderate need cases of the AC in which males (10.6%) showed a statistically significant higher percentage than females (3.9%). Regarding the type of dentition, there was no statistically significant difference in orthodontic treatment needs between children having a mixed dentition stage and those with permanent dentition. A strong association was noted between the DHC and AC of IOTN.
Conclusion: The treatment needs of the examined children in Beni-Suef are comparable to other populations worldwide.
