Abstract
The article published in the January issue on infraoccluded deciduous molars (Dias C, Closs LQ, Fontanella V, de Araujo FB. Vertical alveolar growth in subjects with infraoccluded mandibular deciduous molars. Am J Orthod Dentofacial Orthop 2012;141:81-6) was well researched and resourced. The authors stated that “There are 2 main theories aimed at explaining the etiology of ankylosis: one focuses on local clinical findings, and the other on genetics.” However, I was concerned that the word “tongue” did not appear in the article, although it is known to be associated with lateral open bites of many kinds. It does not seem possible to measure long-term tongue posture, but I do not think that should be an excuse to ignore it, since we are in no position to deny that the tongue could be a major factor in some malocclusions. Vertical alveolar growth in subjects with infraoccluded mandibular deciduous molarsAmerican Journal of Orthodontics and Dentofacial OrthopedicsVol. 141Issue 1PreviewOur objective was to compare vertical alveolar growth in areas adjacent to infraoccluded deciduous molars with growth in areas of deciduous molars and normal occlusion for a period of at least 1 year by using digital subtraction radiography.
