Remarkable difference in perception among both groups was observed in picture of Diastema
closure (pic 1), pink spot (pic 2), chalky white appearance (pic 9) and altered size of lateral incisor and canine (pic 11), which were marked "good" by non-dental students.

This dissatisfaction with dental appearance showed a statistical relationship with the adolescents' sex and with some of the occlusal components, such as the following: median maxillary diastema
, mandibular irregularity, anterior open bite and the antero-posterior molar relation, evaluated by the Dental Aesthetic Index.
These include the total number of teeth in each mandibular ramus, that in "K." boyacensis is approximately 24, while in MP111209-1 is not greater than 18 (although the number of mandibular teeth may differ among individuals of the same species (Ketchum and Benson, 2011a)); the diastema
is broader in "K." boyacensis than in MP111209-1; the rib facets of the posterior cervical vertebrae are divided anteroposteriorly into two areas in "K." boyacensis, but not in MP111209-1, and the propodials are slender in "K." boyacensis compared with those of MP111209-1(table 2).
The boys assigned similar median AC scores to photos D and E, which corresponded to severe dental diastema
and mild anterior OB; and ascribed the lowest median AC score to mild ROJ and mild dental diastema
The weak extension of the canine process and short diastema
in Hexaprotodon can be considered the primitive characters of hippopotamids, occurring in taxa known from the late Miocene and early Pliocene (Coryndon, 1977, 1978; Geze, 1980; Harris, 1991).
If the patient has lost bone support, the center of resistance moves apically, and the same force against the crown produces greater pressure in the periodontal ligament of a periodontally compromised tooth than in a normally supported one intrusion of elongated incisors which is the logical solution to close the anterior diastema
. [7, 8] Due to the risks of loss of the bone support around teeth and root resorption during intrusion, very light forces should be applied.
en el que se uso el modelo generado con los datos de calibracion (60% de los datos, 40% para su validacion), esto para evitar un sobreajuste, por la gran cantidad de registros que se tenia para esta especie.
It has been suggested that relapse might occur after treatment of small initial diastema
(13) and measures must be taken to avoid relapse.
El foramen mental esta ubicado cerca al diastema
. El proceso capsular del incisivo inferior es ligeramente globoso.
