OBJECTIVES: During the treatment of chronic apical periodontitis and pulp necrosis the main role is to irrigate the root canal. AIM: The aim of this in vivo study was to irrigate with 0.9% NaCl (Natrium Chloride), 2.5 % NaOCl (Sodium Hypochlorite Solution, Sigma Aldrich - Germany) and 2% CHX (Chlorhexidine Digluconate Solution, Sigma Aldrich - Spain) combined with Gaseous Ozone (Prozone WH, Austria). MATERIAL AND METHODS: This study was realised in the University Dentistry Clinical Centre of Kosovo (UDCCK), respectively in the Department of Endodontic and Dental Pathology, Dental Branch, Faculty of Medicine, Prishtina, Kosovo...

OBJECTIVES: To investigate diagnostic accuracy of panoramic radiography in detecting maxillary sinus floor septa by means of a multi-observer receiver operating characteristic (ROC) analysis and a standardized protocol for reporting (STARD protocol; Clin Chem 49(1):1-6, 2003). MATERIAL AND METHODS: From our database, 25 cone beam computed tomographies (CBCTs) were selected with one maxillary sinus floor septum (height ≥ 2.5 mm). For the same patient, a recent panoramic radiograph (PAN) had to be available in the database...

The aims of this study were to find the incidence of bifurcation of the inferior dental nerve (IDN) canal, to describe the characteristics of this variant, and to examine the sensitivity and specificity of dental panoramic tomography to identify it. We classified bifurcations by size and position relative to the main canal and the lower third molar using cone-beam computed tomography (CT) and dental panoramic tomography. In our study of 281 patients, 106 (38%) had bifurcations, and in one quarter, these were classified as large accessory canals...

Gorlin-Goltz syndrome (GGS), also known as nevoid basal cell carcinoma syndrome, is an autosomal dominant inherited disorder with high penetrance and variable expressivity. The classic triad originally described by Gorlin and Goltz in 1960 is composed of multiple nevoid basal cell carcinomas (NBCCs), odontogenic keratocysts (OKCs) in the jaws and bifid ribs. in 1977, this triad was modified by Rayner et al, and to GGS diagnosis, the OKCs had to appear in combination with calcification of the cerebellar falx or palmar and plantar pits...

The aim of this study was to analyze the influence of dental implants on the radiographic density of the peri-implant region in tomographic and radiographic examinations. A sample of 21 dental implants from 10 patients with Brånemark-protocol prostheses was evaluated based on postoperative control images, including periapical radiography (paralleling technique), panoramic radiography, and cone beam computed tomography (CBCT). The density means of 6 defined areas near dental implants were calculated and compared considering their locations and the different imaging examinations...

The ability of dental students to interpret digital panoramic radiographs (PANs) of edentulous patients has not been documented. The aim of this retrospective study was to compare the ability of second-year (D2) dental students with that of third- and fourth-year (D3-D4) dental students to interpret and identify positional errors in digital PANs obtained from patients with complete edentulism. A total of 169 digital PANs from edentulous patients were assessed by D2 (n=84) and D3-D4 (n=85) dental students at one Canadian dental school...

When planned and implemented appropriately, single-unit implant dentistry in the smile zone can be an excellent alternative to attempting to save a failing natural tooth. Historically, implant success has revolved around assessment of osseointegration and the healing of bone around the implant, without much regard for esthetics upon completion. As implant dentistry has evolved, the expectations of both restoring clinicians and patients have expanded to emphasize the esthetic outcome as well as faster treatment with immediate implant placement...

This step-by-step article describes radiographic imaging of the horse's teeth and paranasal sinuses with standard radiographic equipment. Obtaining radiographs of the horse's skull that are of diagnostic quality can be challenging. The descriptions offered in this article can help practitioners become more comfortable with obtaining diagnostic images, which will improve recognition of radiographic signs of dental and paradental pathology.

OBJECTIVE: To evaluate the clinical performance of impedance spectroscopy, laser fluorescence, and bitewing radiographs in detecting occlusal caries and compare them with visual scores. METHOD AND MATERIALS: In 62 adults, one occlusal surface per person was selected and independently examined by two examiners using the visual ICDAS scoring system, CarieScan PRO (ACIS), DIAGNOdent pen (LF-pen), and bitewing radiographs. The procedures were repeated within 1 to 4 weeks...

Cone beam computed tomography (CBCT) has obvious advantages over regular radiography in diagnosis of complex diseases. Objective of this study is to report a case of a mandibular jaw ameloblastoma recurring cyst, which represents a benign tumor of odontogenic epithelium, using CBCT imaging technology. CBCT examination of the patient suffering with recurrent lower jaw cyst (relapsing four years after surgery) showed a decrease in irregular bone density and appearance of a honeycomb pattern (3.5 cm×2.5 cm×1...

Background: Cleidocranial dysplasia is a type of skeletal dysplasia, which is primarily characterized by delayed ossification of skeletal structures. It causes facial and oral abnormalities, resulting in difficult airway management and neuraxial anesthesia. Case presentation: The patient was a 24-year-old primipara (height 138 cm, weight 42 kg) with a hypoplastic right clavicle, patent fontanelles, dental malalignment, and a high palate. She was diagnosed with cleidocranial dysplasia at birth, although gene examination has not been performed...

BACKGROUND: Forensic odontologists commonly incise the skin for post-mortem dental examinations when it is difficult to open the victim's mouth. However, it is prohibited by law to incise dead bodies without permission in Japan. Therefore, we attempted using extra-oral dental radiography, using a digital X-ray equipment with rechargeable batteries, to overcome this restriction. MATERIALS AND METHODS: A phantom was placed in the prone position on a table, and three plain dental radiographs were used per case: "lateral oblique radiographs" for left and right posterior teeth and a "contact radiograph" for anterior teeth were taken using a flat panel X-ray detector and a hand-held X-ray generator...

CONTEXT: Patients with disabilities represent a population with special needs whose dental care management constitutes a public health problem. This article describes dental care of disabled people in a hospital dental care unit to highlight the difficulties encountered and propose ways to improve this care. METHODS: A retrospective descriptive study was carried out on patients followed between 2010 and 2016 as part of the partnership between the Albert Chenevier Hospital odontology department and the RHAPSOD'IF network...

OBJECTIVE: To investigate the association between tooth loss and craniofacial factors with changes in mandibular condylar morphology. METHODS: A total of 123 patients participated in this cross-sectional study. The mandibular condylar morphology was evaluated using digital panoramic radiography. The exposure variables included gender, age group, molar relationship, facial growth pattern, facial asymmetry, dental midline, posterior crossbite, presence of fixed dental prosthesis, and tooth loss...

OBJECTIVES: The aim of this pictorial review is to illustrate the use of CBCT in a broad spectrum of musculoskeletal disorders and to compare its diagnostic merit with other imaging modalities, such as conventional radiography (CR), Multidetector Computed Tomography (MDCT) and Magnetic Resonance Imaging. BACKGROUND: Cone Beam Computed Tomography (CBCT) has been widely used for dental imaging for over two decades. DISCUSSION: Current CBCT equipment allows use for imaging of various musculoskeletal applications...

Aim: The aim of the present study is to clarify the possible application of orthopantomogram (OPG) for evaluating craniofacial specifications such as angular and linear measurements of the mandible by comparing with lateral cephalogram. Materials and Methods: OPG and lateral cephalogram were taken from 100 patients of age group 16-35 years from Chettinad Dental College and Research Institute. Linear measurements (body length and ramus height) and angular measurement (gonial angle) were assessed both in lateral cephalogram and OPG...
