ALMEIDA, Eliete Rodrigues de; NARVAI, Paulo Capel; FRAZAO, Paulo  and  GUEDES-PINTO, Antonio Carlos. Revised criteria for the assessment and interpretation of occlusal deviations in the deciduous dentition: a public health perspective. Cad. Saúde Pública [online]. 2008, vol.24, n.4, pp.897-904. ISSN 1678-4464.

Secondary data from a randomized sample of Brazilian preschool children were analyzed to evaluate the prevalence of occlusal deviations in the deciduous dentition that can adversely affect the permanent dentition, using revised criteria. Overjet and overbite used cut-off points described in the literature to exclude mild malocclusion cases. Overjet > 3mm and overbite > 3mm were present in 16% and 7% of the children, respectively. On the sagittal plane, only bilateral deviations were considered: molar relationship in distal step (9.7%) and mesial step (6%) and canine relationship class 2 (11%) and class 3 (2.9%). Regarding other occlusal deviations, severity criteria were not reported in the literature. Crude prevalence rates of openbite (27.9%), posterior crossbite (11.3%), and crowding in the maxillary arch (7%) and mandibular arch (11.3%) were recorded. The assessment of malocclusion in the deciduous dentition should focus on the severity of occlusal deviations for the identification of cases and non-cases that are relevant to public health. Need for further consensus and improvement in the interpretation of epidemiological data on malocclusion related to this developmental stage is emphasized.
