Background: Cohort studies have evaluated dental arches of children. Aim: To evaluate the volumetric, linear, palatal surface area, and the dental arch superimposition of participants with bilateral complete cleft lip (BCL) and bilateral cleft lip and palate (BCLP) surgically treated in a specialized hospital. Design: One hundred and thirty six digitized dental models evaluated before cheiloplasty (T1), after cheiloplasty (T2), and after palatoplasty (T3). The stereophotogrammetry software analysed the volume, palate superimposition, linear, and area measurements. Results: In BCL group, at T2, C-C', T-T', area, and volume significantly increased (P = .000, P < .000, P = .010 e P = .003, respectively). In BCLP group, the comparison T3 × T1 showed that C-C' decreased, whereas T-T' and the area increased (P < .000, P < .000, P = .000). The volume increased at T2, but decreased at T3 (P < .000) in participants with BCLP. The intergroup analysis revealed that C-C', T-T', I-C', and I-C were significantly smaller in participants with BCLP (P < .000, P = .016, P = .001 e P = .020, respectively), whereas the volume, superimposition, and area were statistically similar between groups (P > .05). Conclusion: The comparison between bilateral orofacial clefts showed reduction in the transversal and anteroposterior linear measurements, but not in the area and volume, which was confirmed by the superimposition of the dental arches.

Abstract

Background: Cohort studies have evaluated dental arches of children. Aim: To evaluate the volumetric, linear, palatal surface area, and the dental arch superimposition of participants with bilateral complete cleft lip (BCL) and bilateral cleft lip and palate (BCLP) surgically treated in a specialized hospital. Design: One hundred and thirty six digitized dental models evaluated before cheiloplasty (T1), after cheiloplasty (T2), and after palatoplasty (T3). The stereophotogrammetry software analysed the volume, palate superimposition, linear, and area measurements. Results: In BCL group, at T2, C-C', T-T', area, and volume significantly increased (P = .000, P < .000, P = .010 e P = .003, respectively). In BCLP group, the comparison T3 × T1 showed that C-C' decreased, whereas T-T' and the area increased (P < .000, P < .000, P = .000). The volume increased at T2, but decreased at T3 (P < .000) in participants with BCLP. The intergroup analysis revealed that C-C', T-T', I-C', and I-C were significantly smaller in participants with BCLP (P < .000, P = .016, P = .001 e P = .020, respectively), whereas the volume, superimposition, and area were statistically similar between groups (P > .05). Conclusion: The comparison between bilateral orofacial clefts showed reduction in the transversal and anteroposterior linear measurements, but not in the area and volume, which was confirmed by the superimposition of the dental arches.
