Abstract:
Background: Premature Extraction of Primary Teeth (PEPT) is a common finding in any paediatric population. However, there are no systematic reviews or studies to date providing a reliable evidence base regarding PEPT and orthodontic need. Aims: To conduct a systematic review to systematically evaluate the effect of PEPT on malocclusion and to conduct a study in Bradford and Airedale district to explore this association. Materials and Methods: A thorough search strategy was developed and used to locate studies assessing the effect of PEPT on malocclusion and space loss. A methodological assessment was also carried out for included studies to assess risk of bias. A regional oral epidemiological survey of 12-year-old children in Bradford and Airedale was carried out in 2008/2009. As part of this oral health needs assessment, information on orthodontic need was also collected. A study group was formed of the children who had their orthodontic need assessed in the oral epidemiological survey and had their dental records available through the Salaried Dental Service (SDS). A multilevel logistic regression model was developed to explore the factors associated with orthodontic need. Results: Twenty-five studies were appraised for the systematic review. There was only one study assessing malocclusion following PEPT that fulfilled the predefined inclusion criteria which concluded that PEPT led to an increased incidence of malocclusion. Out of 366 children who were surveyed in the oral epidemiological survey from Bradford and Airedale, 116 had accessed SDS. Out of those, 107 children met the inclusion criteria. An increased total number of PEPT was positively associated with orthodontic need (odds ratio: 1.18, CI – 1.01 to 1.37). Conclusions: There was some evidence to suggest that malocclusion and thus orthodontic need was increased by the previous history of PEPT. The only predictor exhibiting significance was the total number of primary teeth lost.
