periapical periodontitis maxillary sinus

The etiopathology of maxillary sinusitis of dental origin (MSDO) is well established, and chronic apical periodontitis is the second most common cause of all dental-induced sinusitis incidents. The literature presents no common treatment protocols for MSDO and very few studies address the impact of root canal treatment (RCT) in its management. The literature presents cases of maxillary sinusitis resolution after performing a multivisit nonsurgical endodontic treatment, yet none described complete healing of MSDO as a result of single-visit nonsurgical RCT...

STATEMENT OF THE PROBLEM: Odontogenic infections such as periapical lesions (PLs) can cause changes in the adjacent tissues. Infection of the maxillary posterior teeth can be easily transmitted to the maxillary sinus and cause changes in the maxillary sinus mucosa. Cone-beam computed tomography (CBCT) has high accuracy and sensitivity for detection of odontogenic lesions and is efficient for maxillary sinus assessment. PURPOSE: This study aimed to assess the maxillary sinuses for abnormalities such as mucosal thickening, polyps, and periostitis, and evaluate the periapical status of maxillary posterior teeth considering the presence of PLs, their size and distance from the sinus floor by evaluating CBCT images...

Background. This retrospective study aimed to investigate the effect of various dental and maxillary sinus variables on maxillary sinus mucosal thickness (MT). The variables included periodontal bone loss (PBL), periapical status, dental restorations of posterior maxillary teeth, and the distance from the root apices to the sinus mucosa. Methods. Cone-beam computed tomography (CBCT) images of the maxillary sinuses (n = 600) in 300 patients were examined. The sinus MT and the distance of the roots from maxillary sinuses were measured...

Although regenerative endodontic procedures (REPs) have become one of the widely accepted treatment modalities for necrotic immature teeth with apical periodontitis, little is known about the long-term outcomes and the effect of orthodontic tooth movement on this procedure. This report presents a case that underwent two REPs and orthodontic treatment over a period of seven years. A 9-year-old male was referred for evaluation of traumatized maxillary central incisors. Based on clinical and radiographic examinations, a diagnosis of pulp necrosis with acute apical abscess was established...

Background and Objectives : Odontogenic sinusitis is a frequently underestimated pathology with fewer symptoms in patients with periapical lesions, periodontal disease, or iatrogenic foreign bodies in the maxillary sinus. The aim of our study was to determine the correlation between maxillary sinusitis and periapical lesions using cone-beam computed tomography (CBCT) imaging and histological and immunohistochemical investigations. Materials and Methods: A total of 1450 initial patients diagnosed with maxillary sinusitis in the Ear-Nose-Throat (ENT) Department, University of Medicine and Pharmacy "Grigore T...

OBJECTIVE: The aim of the study was to study the structure of odontogenic sinusitis and identify iatrogenic etiological factors. MATERIAL AND METHODS: A retrospective analysis of the case histories of patients operated from 2015 to 2019 with a diagnosis of «Sinusitis» in the Clinical City Emergency Hospital in Tashkent, Republic of Uzbekistan in the department of emergency maxillofacial surgery was carried out. The total number of patients was 333 people: 105 (31...

Odontogenic infections can directly trigger maxillary sinusitis. CBCT is an excellent choice for precise examination of maxillary sinuses and hard tissues within the oral cavity. The objective of this retrospective and the cross-sectional study was to analyze the influence of odontogenic conditions on the presence and intensity of maxillary sinus mucous membrane thickening using CBCT imaging. Moreover, periodontal bone loss and anatomic relationship between adjacent teeth and maxillary sinuses were assessed to evaluate its possible impact on creating maxillary thickening...

BACKGROUND: Sagittal fractures of equine cheek teeth are commonly observed during oral examination. There are few reports on the apical and endodontic pathology associated with such fractures seen during computed tomographic (CT) examination. OBJECTIVES: This study aimed to document the prevalence of CT changes indicative of apical disease in equine cheek teeth, which have suffered a sagittal fracture involving the clinical ± reserve crown. STUDY DESIGN: This study is a retrospective case series...

BACKGROUND: The volume of residual alveolar bone is critical to the survival of dental implants. When the volume of alveolar bone in the posterior maxillary region is less than 4 mm, maxillary sinus floor elevation (MSFE) with the lateral approach is an effective option. Traditionally, this standard approach is usually conducted at 4-6 months after tooth extraction (standard MSFE). However, defective dentition due to extraction can impair mastication during the period of bone remodeling, especially if the molars on both sides are severely compromised and must be extracted...

PURPOSE: Endodontic disease is one of the most common causes of bacterial odontogenic sinusitis (ODS). Diagnosing ODS of endodontic origin involves otolaryngologists confirming sinusitis, and dental specialists confirming endodontic sources. The purpose of this study was to conduct a multidisciplinary literature review to highlight clinical and microbiological features of ODS, and the most optimal diagnostic modalities to confirm endodontic disease. METHODS: An extensive review of both medical and dental literature was performed by rhinologists, endodontists, and an infectious disease specialist...

BACKGROUND/PURPOSE: Maxillary posterior teeth have close anatomical proximity to the maxillary sinus floor. The aim of this retrospective study was to evaluate the associations between maxillary sinus membrane thickening and the adjacent teeth health by cone-beam computed tomography (CBCT). MATERIALS AND METHODS: CBCT images were collected from 235 Taiwanese patients. The sinus mucosal thickening >2 mm is considered a pathologic sinus membrane. Demographic data such as sex, age, the thickness of sinus membrane, and the adjacent teeth health were recorded, graded, and analyzed...

RATIONALE: Three root canals (mesiobuccal, distobuccal and palatal) are rarely found (frequency <1%) in the maxillary central incisor even though root canal morphology in maxillary premolars is highly variable. Therefore, research papers showed that dentists can easily miss the root canals in diagnosis and inflammatory diffusion; which could cause unsuccessful root canal treatment leading to various possible infections and no change in original inflammations. In this report, the diagnose and clinical management of an unusual case of a maxillary center incisor with three independent roots and three root canals is presented, along with a demonstration of using CBCT (Cone Beam Computed Tomography) and collaborate with other departments to successfully accomplish an accurate diagnosis of the morphology and quantity of the root canal system...

OBJECTIVE: To investigate an association between odontogenic infections (OI) and maxillary sinuses pathologic disorder (MSPD). The distance between the sinus floor and the root apex of upper posterior teeth was also assessed. METHODS: Out of 4,402 cone beam computed tomography scans, 230 were selected, and 431 teeth were evaluated regarding the presence of OI: bone loss with furcation involvement, periapical and endodontic-periodontal lesions. The maxillary sinuses were assessed regarding the presence of MSPD, which was considered as mucosal thickening, opacification of the sinus and mucous retention cyst...

BACKGROUND: The treatment of chronic odontogenic and nonodontogenic rhinosinusitis is different. It requires the elimination of odontogenic cause and optimal sinus surgical treatment. To date, there are no clear indications when sinus surgical treatment is necessary. OBJECTIVE: Our aim was to define clear indication(s) for sinus surgical treatment in patients with chronic odontogenic rhinosinusitis after elimination of odontogenic cause. METHODS: A group of 96 patients with chronic odontogenic rhinosinusitis caused by apical periodontitis completed a Sino-Nasal Outcome Test 22 (SNOT-22) questionnaire with incorporated additional symptom "malodor" before treatment...

Odontogenic sinusitis (OS) accounts for about 10-20% of all the sinusitis occurring in maxillary sinus. OS may result due to periapical pathology, severe periodontitis, peri-implantitis, or oroantral communication due to displacement of tooth root into the sinus. Very rarely OS can be due to an impacted tooth in the maxillary sinus for which very few case reports are found in literature. The author presents a case report of 24 years female suffering from unilateral chronic sinusitis since 1 year caused due to impacted third molar tooth in left maxillary sinus associated with odontogenic keratocyst that was managed both medically and surgically...

The palatogingival groove is a developmental anomaly that typically starts near the cingulum of the maxillary incisors and extends along the roots at varying lengths and depths. Severe grooves that extend to the root apex often lead to complex combined periodontal-endodontic lesions. There are various therapeutic options available for these cases; however, the prognosis is unfavorable. Here, we report the successful surgical treatment of 3 cases of maxillary lateral incisors with severe palatogingival grooves using intentional replantation with a 2-segment restoration method...
