Dentoalveolar Growth Inhibition Induced by Bone Denudation on Palates: A Study of Two Isolated Cleft Palates with Asymmetric Scar Tissue Distribution

Abstract

Analysis via flowmetry showed that the palatal scar tissue area was limited to the anterior tooth region on the right (unaffected) side but extended posteriorly to the premolar region on the left (affected) side in both subjects. The two girls had similar dentoalveolar structures, with the dental and alveolar arches deflected lingually at the deciduous molar area on the affected side. There were no differences in the buccolingual inclination of deciduous molars or in the vertical growth of the alveolar processes between the affected and unaffected sides. In both girls, bone denudation in the premolar region appeared to result in less than 3 mm of displacement of the teeth palatally, with no change in lingual inclination. Any effects of scar tissue on the vertical development of the alveolus were not substantiated.

Incisor and molar overjet, arch contraction, and molar relationship in the mixed dentition in repaired complete unilateral cleft lip and palate: A qualitative and quantitative appraisal

“…Ross 3,4 suggested that postsurgical scar tissue induced the periodontal ligament to pull anterior teeth backward toward the palate. Smahel et al 2 and Ishikawa et al 5 described that the lingual inclination of the dentoalveolar process on the cleft side was a result of periosteal denudation of the bone and its scar tissue. Wijdeveld et al, 23 in their histologic studies on beagle dogs, showed that the scar tissue covering denuded bone on lateral sides of the palate were mainly transversally orientated collagenous fibers that lacked blood supply and elastic fibers and had a continuation with the periodontal ligament.…”

“…The permanent central incisor is palatally inclined, [1][2][3][4] while the deciduous canine and deciduous molars are palatally inclined or displaced along with palatal collapse of the maxillary lateral segment. 5 Numerous studies of maxillary dental arch dimension in UCLP at different ages have shown significantly smaller than normal maxillary arch width and length. [6][7][8][9][10][11] While studies have described arch contraction in different regions of the arch in UCLP, maxillary arch width differences between the cleft and noncleft sides have been rarely discussed.…”

Permanent maxillary central incisor and first molar rotations in the mixed dentition in repaired complete unilateral cleft lip and palate and their relationship with absence of teeth in their vicinity

“…Ross and Johnston 2 suggested that postsurgical scar tissue induced the periodontal ligament to pull anterior teeth backward and rotated toward the palate. Ishikawa et al 15 described that the lingual inclination of the dentoalveolar process on the cleft side was a result of periosteal denudation of the bone and its scar tissue. Smahel et al 3 suggested that rotation of incisors could be a result of a lack of space at the end of the alveolar segment and might be associated with other factors such as absence of the lateral incisor and an anomaly of the dental anlage.…”

Laser Doppler flowmetry in endodontics: a review

“…Another indication of LDF is in monitoring pulpal reactions to orthodontic procedures (McDonald & Pitt Ford 1994, Barwick & Ramsay 1996, Brodin et al. 1996, Ishikawa et al. 1998, 1999, Ikawa et al.…”
