The aim of this study was to evaluate orthodontic treatment needs among Ferlo scholars. The design of the study was descriptive and transversal. For Inclusion criteria, children must live in Widou or live around Widou’s school at least 6 km, be students at primary school of Widou Thiengoly, have a general health state which permits a clinical oral examination and teacher’s and/or parent’s agreement. The investigation was exhaustive and concerned the only school of the locality. More of 4/5 schoolchildren was 10.25 years ± 2.15 old. The majority (83.74%) of children presented an overjet between 0 and 3.5 mm, 1.63% presented a crossbite and 15.45% had OIM and RC different over to 2 mm. More of 30% of schoolchildren presented an overbite between 1 and 2 mm. More of 1/10 of them had an aesthetic teeth perception classified levels 8.9 and 10 corresponding to an orthodontic treatment needed according to IOTN while 20.33% had a score of 4 and 3.25% recorded score of 5 corresponding to a high treatment needed according to IOTN.
