Abstract:
OBJECTIVETo evaluate the craniofacial characteristics of the Class II malocclusion patients with mouth-breating by posteroanterior cephalometry.
METHODSTo measure craniofacial width of the 12 Class II malocclusion patients with mouth-breathing, and to compared these measures with corresponding measures in a group of normal children.
RESULTSThe width of the maxillary base bone (J-J) was less than that in normal children significantly (P < 0.01). The mouth-breathing children's upper and lower arch width (at first molar and cuspid) were comparatively narrower, and lateronasal width (Lap-Lap) was narrower too.
CONCLUSIONMouth breathing may lead to craniofacial morphological abnormal development in craniofacial transverse structures.
