AIM The study aimed to investigate the proximity of maxillary posterior teeth roots to maxillary sinus and measure the distance of maxillary posterior teeth roots and the sinus floor as well as the thickness of bone between the roots and alveolar cortical bone using Denta scan®. MATERIALS AND METHODS The study samples include Denta scan® images of fifty patients with normally erupted bilatera...

Introduction/Objective. Class III malocclusion is caused by changes in skeletal and/or dentoalveolar structures with a typical mesial relationship of posterior teeth. The ?Y? appliance and the screw according to Bertoni can be used treating maxillary retrognathism period mixed dentition. aim study was determine compare on patients treated Y Bertoni. Methods. Forty were included this study. samp...

Cholesterol granuloma (CG) is a tissue reaction in response to the accumulation of cholesterol crystals rarely found in the maxillary sinus. The etiopathogenesis of maxillary sinus CG remains unclear. We reviewed the literature and added two new reports of cholesterol granuloma in maxillary sinus related to endodontically treated maxillary posterior teeth. The first report refers to a 45-year-o...

Normal craniofacial and dental growth and development is dependent on growth hormone (GH) and insulin-like growth factor I (IGF-I). Deficiencies of either during childhood cause diminished growth of the maxilla and (to a greater degree) the mandible. Dental development/eruption also is compromised. Conversely, excessive GH/insulin-like growth factor I causes overgrowth, with the mandible again ...

INTRODUCTION Transverse maxillary deficiency is frequently observed in patients who seek orthodontic treatment. In skeletally mature patients, transverse maxillary deficiency can be treated with surgically assisted rapid palatal expansion (SARPE). Forces delivered by the expander produce areas of compression in the periodontal ligament, which could lead to alveolar bone resorption and possible ...

Purpose: The aim of this study was evaluation cephalometric changes in treatment skeletal class III malocclusion using miniscrews and intermaxillary closing coil springs. Material methods: Ten patients with Class due to maxillary deficiency were selected, their age range from 12 15 years old erupted all permanent teeth. Miniscrews (Hubit, Hubit co, Korea) inserted (1.6 mm diameter, 10 length) u...

The Drosophila maxillary palpus that develops during metamorphosis is composed of two elements: the proximal maxillary socket and distal maxillary palp. The HOX protein, Proboscipedia (PB), was required for development of the proximal maxillary socket and distal maxillary palp. For growth and differentiation of the distal maxillary palp, PB was required in the cells of, or close to, the maxilla...

introduction: atypical infratemporal fossa infections are rare and potentially fatal.   case report: a case of an aspergillosis localized in the infratemporal fossa and another case of tuberculosis of the infratemporal fossa originating from the maxillary sinus, is described. the first patient was immunocompromised and showed symptoms of facial numbness; whereas the other was an immunocompetent...
