RESUMO

Objetivo:

Avaliar a prevalência de pacientes de Ortodontia com caninos superiores permanentes inclusos (CSPI), e sua localização e associação com a agenesia dos incisivos laterais superiores permanentes (ILSP).

Materiais e métodos:

A amostra foi constituída a partir dos prontuários de 825 pacientes, sendo o Grupo Experimental (GE) composto de 27 pacientes, 14 do sexo feminino (idades entre 10,5 anos e 15,4 anos) e 13 do sexo masculino (idades entre 11 anos e 17,6 anos), com CSPI e o Grupo Controle (GC) por 27 pacientes sem CSPI, pareados com GE de mesma idade e sexo. Analisaram-se a anamnese, o exame clínico, os modelos, as fotografias, radiografias panorâmica, periapicais e oclusais, telerradiografias cefalométrica lateral e póstero-anterior, em ambiente escurecido com negastocópio e lupa testeira (aumento 4x).

Resultados:

Observaram-se 27 pacientes (3,27%), totalizando 31 caninos inclusos, 51,85% ocorreram no sexo feminino e 48,15% no masculino; o Teste de Diferença de duas proporções verificou maior número de agenesias de ILSP(7) no GE do que no GC (1) (p = 0,0255) e que a ocorrência de agenesias concentrou-se nos pacientes comCSPI na região palatina (p = 0,0227).

Conclusão:

A prevalência de caninos superiores permanentes inclusosé de 3,27%, mais frequente por palatino e há dependência entre a prevalência aumentada de agenesia deincisivos laterais superiores permanentes e a inclusão palatina de caninos superiores.
ABSTRACT

Objective:

The purpose of this study was to evaluate the prevalence of included permanent maxillary canines (IPMC) in orthodontic patients, their location and association of agenesis of the permanent upper lateral incisors (PULI). Materials and

methods:

A sample from the medical records of 825 patients was analyzed. The experimental group (E.G.) was composed of 27 patients with IPMC, including 14 females (aged from 10.5 to 15.4 years) and 13 males (aged from 11.0 to 17.6 years). The control group (CG) was made up of 27 patients without IPMC, paired with E.G. of the same age and sex. We analyzed clinical histories and clinical examinations, models, photographs; also panoramic, periapical, occlusal and lateral radiographs, and lateral and antero-posterior cephalometric teleradiographs were examined in a darkened room with an illuminated viewbox and headband magnifier (4X magnification).

Results:

There were 27 patients (3.27%) with IPMC, totaling 31 included maxillary canines, 51,85% in females and 48.15% in males. The difference in proportions test found a higher number of cases of PULI agenesis (7) in the E.G. than in the CG (1) (p = 0.0255) and that the occurrence of agenesis was concentrated in patients with palatal IPMC (p = 0.0277).

Conclusions:

The prevalence of included permanent maxillary canines is 3.27%, more frequent in the palatine area. There is dependence between the increased prevalence of agenesis of permanent upper lateral incisors and palatal impaction of maxillary canines.
