This study reports a case of a 10-year-old boy who presented with a chief complaint of not liking the arrangement of his teeth
and the discoloration of an anterior tooth. Mother also complained of a lower lip sucking habit which he performed occasionally
and a one year history of trauma to his anterior tooth which was untreated. On assessment, a diagnosis of Angle's class II
division 1 malocclusion on skeletal pattern 2 complicated by Ellis class IV fracture of tooth 11, proclined 11 and 21,
incompetent lip seal, increased overjet, deep and traumatic overbite, buccal crossbite of 24, moderate spacings in the upper
anterior segment, mild crowding in the lower anterior segment, rotated teeth and exaggerated curve of spee in the lower arch
was made.
A multidisciplinary treatment plan of Orthodontic and Paedodontic management with a two-phase orthodontic treatment was
done. Phase 1 orthodontic treatment was a functional appliance treatment phase using Frankel 2 appliance while Phase 2 was an
upper and lower arch fixed orthodontic appliance treatment (non-extraction protocol) after a root canal treatment of tooth 11
had been carried out. Retention was achieved using a combination of upper and lower fixed lingual retainers and an upper
Hawleys' retainer.
Conclusion: This study presented a successful orthodontic-endodontic intervention in the management of a 10-year-old boy
with Angle's class II division 1 malocclusion on skeletal pattern 2 complicated by a devitalized upper central incisor over a
period of 27 months
