Article Abstract
Objective: The objective of this study was to investigate differences in masseter metabolism by (31)P-Chemical Shift Imaging (CSI) in adult individuals with different vertical facial patterns. The clinical study should be supported by functional findings at the mRNA level after orthognathic surgery.
Study Design: Twenty-two male volunteers (mean age 24.6) were divided into a deep-bite (NL/ML 11.8 ± 2.3°) and open-bite group (NL/ML 34.1 ± 2.6°). Vertical jaw relationship, gonial angle, and masseter volume were defined and compared with the phosphate values obtained from the (31)P spectra. Student t test and regression analysis were used.
Results: Phosphocreatine related strongly to muscle volume (P < .001), gonial angle (P < .001), and ML/NL angle (P < .01). Pi was found to be related to gonial angle (P < .05). Muscle volume was found to be inversely related to ML/NL (P < .01) and to the gonial angle (P < .01).
Conclusions: A difference in masseter muscle metabolism between long- and short-faced subjects was confirmed at rest position.

Post-pubertal effects of the Face Mask Protocol with and without Bite Block appliance in the orthopedic treatment of Class III malocclusion: a comparative evaluation.
Eur J Orthod

Department of Faculty of Medicine and Surgery, UniCamillus International Medical University, Via di Sant'Alessandro 8, 00131 Rome, Italy.
Objectives: The purpose of this retrospective study was to compare the dento-skeletal changes observed in growing Class III patients treated with the Face Mask Protocol (FMP) with and without Bite Block (BB).
Materials: Thirty subjects (12 f, 18 m) who underwent FM/BB therapy were compared to a matched group (FM) of 29 patients (15 f, 14 m) treated without BB. All patients were evaluated before treatment (T0), at the end of active treatment (T1), and at a post-pubertal follow-up observation (T2).

Introduction: The early diagnosis of mandibular asymmetry (MA) in patients with unilateral cleft lip and palate (UCLP) can contribute to its treatment.
Objective: The aim of this study was to evaluate the occurrence and the extent of MA in UCLP patients at different growth stages.
Methods: Cone-beam computed tomography (CBCT) of 47 UCLP patients were included, and divided into two groups (prepubertal stage and pubertal stage).
Evaluation of panoramic images in the assessment of mandibular second molar impaction.

Background: To examine the relationship of various mandibular skeletal features determined from assessment of a panoramic image to the impaction of mandibular second molars in children with late mixed to early permanent dentition.
Material And Methods: Thirty-six panoramic radiographs were collected from two private orthodontic offices of consecutively screened patients in the late mixed to early permanent dentition. Gonial angle, space ratio, ramus ratio and occlusal plane to posterior ramus ratio were analyzed for any significant relationship with mandibular second molar impaction.

Background: The ability to predict the extent and direction of horizontal growth of the patient's face at an early age allows clinicians to timely identify cases that require treatment during the growth period and to ensure that appropriate treatment can be administered.
Objectives: The aim of this study was to investigate the role of the antegonial angle, gonial angle, antegonial notch depth, and the type of the antegonial notch on predicting horizontal facial growth in individuals with normal facial height.
Material And Methods: In this descriptive analytic study, lateral and panoramic radiographs of 180 patients aged 17-30 years with normal facial height who were referred to the School of Dentistry of Qazvin University of Medical Sciences and private dental clinics were investigated.
