thorough knowledge of the morphology and internal anatomy of the root canal system is essential, because it determines the successful outcome of endodontic treatment. the main goal of endodontic treatment is to prevent apical periodontitis and/or to promote the healing of periapical lesion. presence of two canals or roots on the palatal side of the first maxillary molar has rarely been reported...

conclusions it was observed that the success and survival rate of maxillary molar immediate implant was relatively high and similar to those of conventional delayed implants. results immediate implants were most frequently used for incisor and premolar sites and there is very little data available on immediate implantation in the molar area. in this research, we reviewed all the existing papers...

Background: The thickness of maxillary sinus floor may reduce markedly because of protrusion of root apices of posterior teeth into the sinus. The possibility of oro-antral communication after extraction is highest for a maxillary first molar, as this tooth erupts first and is frequently extracted early. Aim: To assess the relationships between the roots of the maxillary first molar and the max...

OBJECTIVES Odontogenic sinusitis usually affects the maxillary sinus but may extend to the anterior ethmoid sinuses. The purpose of this study is to determine the percentage of odontogenic maxillary sinusitis extended to the anterior ethmoid sinuses and determine also the surgical resolution differences between odontogenic maxillary sinusitis and odontogenic maxillary associated to anterior eth...

Volume Objective: To study the size of the maxillary sinus which includes linear and volume measurements. Methods: Three dimensional computed tomography (3D CT) images of 144 Malays (288 maxillary sinuses) with no clinical evidence of craniofacial and maxillary sinus abnormalities were selected. The subjects aged from 0.4 to 30 years (mean = 13.7 ; SD = 8.53), underwent the CT scanning using Ge...

OBJECTIVES The risk factors for maxillary fungal ball are largely unknown. The aim of this study was to determine whether endodontic treatment of maxillary teeth is a risk factor for fungal ball development in the maxillary sinus, and to identify other possible risk factors. METHODS One hundred and twelve case patients diagnosed with maxillary fungal ball (FB group) and age and gender matched...

OBJECTIVE Phenotypical Down syndrome includes pharyngeal and maxillary hypoplasia and, frequently, constricted maxillary arch with nasal obstruction. STUDY DESIGN This clinical trial assessed the effects of rapid maxillary expansion on ENT disorders in 24 children with Down syndrome randomly allocated to receive either rapid maxillary expansion or not. Each group received ENT and speech thera...

AIM To describe vascular anatomy of the maxillary sinus in dentate specimens dissected from human cadavers. METHODS Twenty dentate maxillary specimens were dissected, anatomically prepared, and injected with liquid latex for a better visualization of the maxillary sinus artery. RESULTS We found an intraosseous anastomosis in 100% and an extraosseous anastomosis in 90% of the cases. The ante...

Aim This study aims to investigate the root canal anatomy of human extracted permanent maxillary anterior teeth in patients reporting to our dental institution in Chennai using cone beam computed tomography (CBCT). Materials and Methods A total of 285 maxillary anterior teeth comprising of 100 central incisors, 85 lateral incisors, and 100 canines extracted from various patients reporting to ...

Background For dental implant planning in maxillary posterior region, it is essential to know their relationship with maxillary sinus. Maxillary posterior teeth affected by chronic periodontitis usually have a poor prognosis, ultimately leading to tooth loss. Following tooth loss, significant bone resorption occurs resulting in compromised remaining bone support for dental implant placement. ...
