Lateral cephalometric radiography is commonly used as a standard tool in orthodontic assessment and treatment planning. The aim of this study was to evaluate the available scientific literature and existing evidence for the validation of using lateral cephalometric imaging for orthodontic treatment planning. The secondary objective was to determine the accuracy and reliability of this technique...
The aim of the study was to analyse the aesthetic evaluation of head photographs of treated individuals with clefts by laypeople and professionals and to investigate how certain cephalometric variables could be related to their rating. A set of five standardized head photos (frontal, both laterals, three-quater right and left) of 12 Caucasian patients with treated unilateral cleft lip and palat...
Most cephalometric analyses make extensive use of angular measurements. This usage is based on the assumption that angular measurements for a particular individual tend to remain relatively constant with respect to time, ie, that they are affected minimally by growth. The tenability of this assumption is challenged in several instances on the basis of the results of a cross-sectional cephalomet...
Quantification of the expectation of craniofacial growth during the pubertal growth spurt (PGS) is helpful in orthodontic diagnosis and treatment planning. Thus, this study investigated whether the stages of the vertebral maturation index (VMI) would be valid for estimating cranial and mandibular growth during the initial stages of PGS, testing the null hypothesis that these structures do not d...
STUDY OBJECTIVES The aims of this study were to comprehensively evaluate the cephalometric features of patients with obstructive sleep apnea syndrome (OSAS), and to elucidate the relationship between cephalometric variables and severity of the apnea-hypopnea index (AHI). PATIENTS The study population consisted of 62 male patients with OSAS, classified into 33 obese patients (body mass index [...
Objective: To evaluate and compare the long-term skeletodental stability of mandibular symphyseal distraction osteogenesis (MSDO) achieved with the use of tooth-borne versus hybrid distraction appliances. Materials and Methods: Posttreatment and follow-up orthodontic records were collected for 33 patients. The 14 patients who underwent distraction with a tooth-borne appliance had a mean follow-...
The aims of this study were to determine Japanese cephalometric norms in the antero-posterior and vertical dimension, and to test the hypothesis that there are racial differences in cephalometric measurements between Japanese and Caucasian norms. Radiographs were obtained from 25 healthy Japanese males (aged 25.1 +/- 2.7 years) and 24 healthy Japanese females (aged 23.6 +/- 1.3 years). Inclusio...
Objective: The aim of this study was to investigate the cephalometric parameters that impair the consistency between the Wits and ANB measurements, which are used in the determination of anteroposterior jaw relationships by logistic regression analysis in the Turkish population. Methods: This retrospective study was conducted on 207 lateral cephalometric radiographs of 100 females (mean age: 15...
The treatment of skeletal disharmonies presents better results when performed during the growth period. The physical changes that occur in every individual express growth, which is ruled by genetic, general and environmental factors. In order to identify such disharmonies and hence concentrate the clinical actions during treatment and influence facial growth, cephalometrics appears as a useful ...
INTRODUCTION Patients with obstructive sleep apnea syndrome usually present with changes in upper airway morphology and/or body fat distribution, which may occur throughout life and increase the severity of obstructive sleep apnea syndrome with age. OBJECTIVE To correlate cephalometric and anthropometric measures with obstructive sleep apnea syndrome severity in different age groups. METHOD...
