BACKGROUND This study assessed the relationship between mucosal thickness (MT) of the maxillary sinus and periodontal bone loss (PBL) and periapical condition of related teeth. We also aimed to identify the association between root apices and the inferior wall of the maxillary sinus using Cone beam computed tomography (CBCT). MATERIAL AND METHODS In this study, CBCT images of 205 patients wit...

Background: Prediction the width of unerupted permanent canines and premolars is far important in assessing the space available to them in an attempt to prevent the future malocclusion. The present study utilized the combined mesio-distal crowns widths of maxillary and mandibular central incisors and first molars to predict the combined mesio-distal crowns widths of maxillary and mandibular can...

Background: Maxillary expansion is a routine procedure performed to correct narrow maxillary arch width and posterior cross-bite. We assume, as orthodontists, that our expansion will be stable long term, but is that assumption correct? Objective: To evaluate the long-term changes in maxillary dental arch widths in patients who were treated with rapid maxillary expansion (RME) appliances followe...

Introduction: The horizontal bony canal in the lateral maxillary wall is the site of anastomosis between the arterial branches from the posterior superior alveolar artery (PSAa) and the infraorbital artery. This anatomic structure is known as the ‘alveolar antral artery’.   Materials and Methods: We performed a literature review. The anatomic location of the alveolar antral artery in the latera...

One of the most significant changes in the area of early treatment in recent decades concerns managing the developing Class III malocclusion. Twenty-five years ago, early intervention for Class III malocclusion was not common in the United States. Management usually involved chincup appliances to restrain mandibular growth, camouflage techniques to advance maxillary incisors and retract mandibu...

We have previously shown that unilateral nasal challenge with antigen causes an increase in the number of eosinophils in the ipsilateral maxillary sinus. Here we aimed to determine whether there was an eosinophil response in the contralateral maxillary sinus after unilateral nasal challenge with antigen. Twenty subjects with a history of seasonal allergic rhinitis and a positive nasal challenge...

OBJECTIVE To identify and evaluate the frequency of the different odontogenic conditions that may lead to maxillary sinusitis. STUDY DESIGN An observational and retrospective meta-analysis was carried out on 770 cases of maxillary sinusitis obtained from a literature review of 15 articles. RESULTS Maxillary sinusitis most commonly manifests itself as chronic maxillary sinusitis. It is more ...
