Infraocclusion – an anomaly in primary dentition

Infraocclusion is a developmental abnormality that affects a tooth lying below the plane of occlusion. It is most common in children with mixed dentition, past the age of six. It is usually noticeable in the posterior part of the dental arch, involving one of the deciduous molars. The presence of infraocclusion can be identified by clinical examination or on radiographs. The aim of the study was to present a literature review on the incidence of infraocclusion in primary molars in children in various populations and on further clinical management. The review covered publications from the last 20 years. The following online databases were searched: PubMed, Google Scholar, and Scopus. Eight scientific papers were eligible for the review. The inclusion criteria were as follows: children, without systemic diseases or syndromes, with infraocclusion. The analysed studies show that the process usually affects a small number of teeth – most children present two infraoccluded molars. The condition shows no predilection for any sex. Across different populations, the percentage of children affected by infraocclusion ranges from 2.8% to 21.8%. With age, there is a decrease in the incidence of
