RESUMO
Problemas de espacio de crecimiento transversal en ambos maxilares pueden ser predichos al conocerse la distancia del ancho intercanino e intermolar. El objetivo del estudio fue determinar valores de medidas transversales de arcadas en pacientes con dentición mixta y dentición permanente del posgrado de Ortodoncia del Instituto Latinoamericano de Estudios Superiores. Estudio observacional descriptivo de corte transversal, se tomaron las distancias lineales horizontales intercaninas temporarios y permanentes, y la distancia intermolar en primeros molares permanentes en modelos de estudio de pacientes entre el 2014 y el 2019. Participaron 144 pacientes de 8 a 32 años, 41,67% tenía más de 15 años, 65,28% eran mujeres y el 52,78% tenía dentición permanente. Los promedios de distancia intercanina maxilar fueron 33,22 ± 3,95 mm en hombres y 33,34 ± 3,90 mm en mujeres, la mandibular 27,30 ± 2,81 y 27,40 ± 2,92 mm respectivamente. La distancia intermolar maxilar en hombres fue de 34,16 ± 3,27 y 34,15 ± 3,26 mm en mujeres; la mandibular fue de 33,97 ± 3,27 y 33,94 ± 3,27 mm respectivamente. Los promedios de la distancia intercanina son similares por edad y sexo, mientras que los promedios de la arcada inferior son menores a los de la arcada superior en ambos sexos. Los promedios para la distancia intermolar son similares por edad, sexo y arcada.
Transverse growth space problems in both maxillaries can be predicted by knowing the intercanine and intermolar width distance. The objective of the study was to determine values of transverse measures of arcades in patients with mixed dentition and permanent dentition of the postgraduate degree in Orthodontics of the Latin American Institute of Higher Studies. Descriptive observational cross-sectional study, the temporary and permanent intercanine horizontal linear distances were taken as well as the intermolar distance in permanent first molars in patient study models between 2014 and 2019. One hundred and forty-four patients aged from 8 to 32 years old participated, 41.67% were over 15 years old, 65.28% were women and 52.78% had permanent dentition. The mean maxillary intercanine distance was 33.22 ± 3.95 mm in men and 33.34 ± 3.90 mm in women, the mandibular 27.30 ± 2.81 and 27.40 ± 2.92 mm respectively. The maxillary intermolar distance was 34.16 ± 3.27 mm in men and 34.15 ± 3.26 mm in women, the mandibular 33.97 ± 3.27 and 33.94 ± 3.27 mm respectively. The averages of the intercanine distance were similar by age and sex, while the means of the lower arcades were lower than those of the upper arcade in both sexes. Means of the intermolar distance was similar by age, sex, and arcade.
RESUMO
Introduction: Canine impaction is an anomaly in which the tooth is prevented from erupting. It occurs when eruption has been delayed and there is radiographic evidence. Objective: To determine the prognosis of impacted canines according to their position in the maxilla by means of different analyses: Ericson & Kurol, Warford and Power & Short; in patients attending private clinics in the city of Asuncion from 2015 to 2020. Methodology: The design is observational descriptive, cross-sectional, using panoramic radiograph measurements. Results: The sample consisted of 37 patients and the 48 canines. It was found that the presence of impacted canines was more frequent in women (69.44%), with unilateral location (70.27%) and palatal position (68.75%). In more than half of the cases the prognosis was unfavorable, however, the concordance was only 75%. There was greater concordance in Warford's prognosis with that of Power & Short (95.91%), while the concordance was lower with that of Ericson & Kurol (81.25%). Conclusion: The frequency of impacted canines in a Paraguayan sample was higher in females, unilaterally located and positioned by palatine. Being unfavorable in more than half of the cases. It is suggested to combine the analyses for projection.
