A Novel Mathematical Method to Diagnose the Transverse Growth Deficit of the Nasomaxillary Complex.

The diagnosis of transverse growth deficit of the maxilla in daily clinical practice is carried out mainly through the experience of a well-trained clinician, which implies a lack of objective criteria applicable in a protocolized manner. The objective of this study was to establish a mathematical method to diagnose maxillary compression in relation to the dimensions of the skull and mandible. Methods: Records of 97 cases with an overall mean age of 9.

Oral colonization by species in orthodontic patients before, during and after treatment with fixed appliances: A prospective controlled trial.

Background: Orthodontic treatment with fixed appliances is associated with changes in oral microbiota, including increased colonization. The fungus can cause oral lesions and infections such as candidiasis and angular cheilitis, and is harmful to both the patient and the orthodontist. Poor hygiene facilitates the colonization of these microorganisms.

Relationship between perception of smile esthetics and orthodontic treatment in Spanish patients.

One of the main objectives of orthodontic treatment is to achieve an esthetic smile. This study set out to analyze differences in the perception of smile esthetics among patients before and after receiving orthodontic treatment. 250 Spanish patients analyzed a single photograph in which, by means of computer software, midline diastema, black triangle, gingival margin of the left central incisor, and gingival ("gummy") smile were altered.
