Cephalometric comparison of obstructive sleep apnea patients and healthy controls.

Objective: This study aimed to compare the cephalometric characteristics of obstructive sleep apnea (OSA) patients with those of healthy subjects and to determine possible relationships between cephalometric measurements of OSA patients and control subjects.

Methods: Standardized lateral cephalograms of 16 OSA patients and 16 healthy controls were obtained. Airway dimensions and dentofacial parameters were measured using a cephalometric analysis program (Dolphin Imaging Cephalometric and Tracing Software, Chatsworth, CA, USA).

Effects of severity and location of nonsyndromic hypodontia on craniofacial morphology.

Objective: To evaluate the effects of severity and location of nonsyndromic hypodontia on craniofacial morphology.

Materials And Methods: A total of 154 patients with at least two or more congenitally missing teeth were selected and divided into two groups (group I [mild]: patients with two to five missing teeth; group II [severe]: patients with six or more missing teeth). The patients with hypodontia were divided into three groups according to the location of missing teeth in the dental arches (anterior, posterior, and both anterior and posterior) and location of missing teeth between the jaws (maxilla, mandible, and both maxilla and mandible).

Effects of airway problems on maxillary growth: a review.

The volume of air passing through the nose and nasopharinx is limited by its shape and diameter. Continuous airflow through the nasal passage during breathing induces a constant stimulus for the lateral growth of maxilla and for lowering of the palatal vault. Maxillary morphological differences exist between patients with airway problems and control groups, identifying a potential etiological role in these patients.
