Tooth transpositions associated with dental anomalies and treatment management in a sample of orthodontic patients

Abstract

The purpose of this study was to determine the distribution of tooth transpositions in a sample of orthodontic patients, describe the accompanying anomalies and report on the management and therapeutic outcome. Overall, the male to female ratio was 4:3, left side predominance was evident, and there was a high incidence of associated dental anomalies. Attempts to correct tooth order usually resulted in untoward effects on periodontal tissues. Consequently, individual anatomical conditions may be decisive in successful clinical management of such cases.

Prevalence of Tooth Transposition

“…15 In the remaining four studies, [19][20][21][22] the samples were relatively big, including more than 4500 patients and allowing for a margin of error between 0.011 and 0.014. 15 In one study 4 the samples were selected from school populations (pupils), in three studies 16,17,20 the samples were retrieved from university orthodontic departments or private orthodontic practices (orthodontic patients), and in the remaining five studies 1,18,19,21,22 the samples were derived from dental schools or private dental practices (dental patients). The inclusion of studies investigating tooth transposition on dental or orthodontic patients represents selection bias, since these samples may not be representative of the underlying population.…”

“…In one study 4 the diagnosis of tooth transposition was based solely upon clinical examination, whereas in the remaining eight studies 1,[16][17][18][19][20][21][22] there was a radiographic confirmation of the transposition. These different methods of diagnosis might imply a detection bias as well.…”

“…In six studies [16][17][18][19][20]22 the ages of the individuals in the sample were undetermined, whereas in one study 21 all ages were included in the sample under investigation. However, tooth transposition cannot be securely diagnosed in individuals aged younger than 7 years.…”

“…In fact, in two cases the authors were contacted about providing us with detailed data of their investigations. 17,23 The authors of the first study 17 sent all the necessary information; however, no reply was received from the authors of the second study, 23 and consequently this article was excluded from the current meta-analysis. No restrictions were applied during the identification process for the years considered, the publication status, or the language of the studies.…”
