PURPOSE: The aim of this study was to evaluate the influence of the implant diameter on marginal bone remodeling around dental implants replacing single molars after a follow-up period of 3 to 6 years. MATERIALS AND METHODS: Patients who received dental implants with an external hexagon platform in healed sites to support a single metal-ceramic crown in the molar region were recalled to the office. The implantation sites and implant length information were recorded, and the implants were divided according to the implant diameter: regular (RP) or wide (WP)...

OBJECTIVES: Plain radiography has been widely used in dentistry. Because of the variability of the quality of equipment, radiographic technique, accuracy of interpretation, and radiation risk to the patients, the field is ripe for the introduction of other newer diagnostic modalities. In this report, we demonstrate the utility of ultrasonography in the diagnostic workup of cystic or cystlike lesions of the jaw. METHODS: We used a transfacial ultrasonographic scanning approach to examine 32 patients with clinical or radiographic presentation of a jaw cyst...

OBJECTIVES: To compare the performance of panoramic radiography (PAN) and cone beam computed tomography (CBCT) in the detection of juxta-apical radiolucency (JAR), as well as to investigate, in CBCT images, if there are factors associated with the detection of JAR on PAN. METHODS: Two oral radiologists assessed the presence of JAR in PAN and CBCT images of 175 individuals (308 mandibular third molars). The cortical plates involvement and the JAR size and location were assessed on CBCT to evaluate if these factors were related to JAR detection on PAN...

OBJECTIVE: To compare the effects of different implant placement and loading protocols on the marginal bone loss (MBL) in beagles by intraoral radiography. METHODS AND MATERIALS: 61 dental implants were inserted on 9 beagle dogs at bilateral lower posteriors according to 8 different protocols: immediate implant placement and immediate loading for 3 months (IIP + IL3) or 6 months (IIP + IL6) and unloading (IIP + UL), immediate implant placement and delayed loading for 3 months (IIP + DL3) or 6 months (IIP + DL6), delayed implant placement and immediate loading for 3 months (DIP + IL3) or delayed loading for 3 months (DIP + DL3) and unloading (DIP + UL)...

Dental panoramic radiographs (DPTs) are commonly taken in dental practice in the UK with the number estimated to be 2.7 million per annum. They are used to diagnose caries, periodontal disease, trauma, pathology in the jaws, supernumerary teeth and for orthodontic assessment. Panoramic radiographs are not simple projections but involve a moving X-ray source and detector plate. Ideally only the objects in the focal trough are displayed. This is achieved with a tomographic movement and one or more centre(s) of rotation...

AIM: Dental surgeons must be aware of the most appropriate endodontic treatments and how to properly conduct them. The aim of this study was to evaluate the knowledge of dental surgeons in Burkina Faso in terms of endodontic treatment procedures. MATERIALS AND METHODS: This descriptive, cross-sectional study was performed during the regular annual conference of the National Board of Dental Surgeons of Burkina Faso, held on February 27 and 28, 2015 in Ouagadougou, through a questionnaire...

Dental pathologies are highly prevalent in pet rabbit populations, making oral radiography an essential tool in the evaluation of lagomorph dentitions. The unique anatomy of the rabbit's mouth limits the examination of the conscious animal to the rostral portion of it's mouth. In addition, the oral examination of an aradicular hypsodont tooth is restricted to the short coronal fraction of its crown. Erstwhile images obtained by the extraoral technique were once considered the most practical and informative tool in rabbit dentistry; however, limited visualization of the key structures of individual teeth became the major drawback of this technique...

INTRODUCTION: The aim of this study was to perform a descriptive analysis of the occurrence of external cervical resorption (ECR) in relation to the patients' characteristics (sex, age, and tooth type) and the potentially involved predisposing factors. METHODS: This study includes data on 284 patients (337 teeth with evidence of ECR) referred to the University Hospital Leuven (Leuven, Belgium) and Endo Rotterdam (Rotterdam, the Netherlands) for diagnosis and treatment from 2010 to 2015...

INTRODUCTION: Arteriovenous malformations (AVMs) are very rare. Only 5% of them occurs in the jaws but they can manifest with dramatic bleeding and be life-threatening. PRESENTATION OF CASE: We report the case of a 11-year-old healthy girl who presented a massive hemorrhage after extraction of the right mandibular first primary molar. This patient received a blood transfusion and was hospitalized in pediatric intensive care unit. CT angiography highlighted an AVM of the mandible...

OBJECTIVE: To evaluate the performance of conventional radiography and photostimulable phosphor (PSP) plate in the detection of simulated internal root resorption (IRR) lesions in early stages. MATERIALS AND METHODS: Twenty single-rooted teeth were X-rayed before and after having a simulated IRR early lesion. Three imaging systems were used: Kodak InSight dental film and two PSPs digital systems, Digora Optime and VistaScan. The digital images were displayed on a 20...

PURPOSE: To determine the caries prevalence and experience in Thuringian infants and to assess their caries risk. MATERIAL AND METHODS: The subjects were participants in a regional preventive programme, a birth cohort study with the aim of preventing caries. In the first year of life, children were invited to a dental examination at the Jena University Hospital. Dental caries was scored using WHO diagnostic criteria at the d1-level without radiography. Children were categorised as being of low, moderate or high risk for caries according to the caries-risk assessment tool of the American Academy of Pediatric Dentistry (AAPD)...

PURPOSE: To evaluate the influence of the collar surface topography on peri-implant marginal bone preservation. MATERIALS AND METHODS: A total of 156 patients who received at least one cylindrical implant of regular diameter with an external-hexagon platform in the posterior region of the maxilla or mandible were recalled to the office for a retrospective evaluation. Implantation sites and implant length information were recorded, and implants were divided according to the collar surface topography: machined (M) or rough (R) surface...

OBJECTIVES: The aim of this study was to identify variables that can be used for osteoporosis detection using strut analysis, fractal dimension (FD), and the gray level co-occurrence matrix (GLCM) using multiple regions of interest (ROIs) and to develop an osteoporosis detection model based on panoramic radiography. METHODS: A total of 454 panoramic radiographs from oral examinations in our dental hospital from 2012 to 2015 were randomly selected, equally distributed among osteoporotic and non-osteoporotic patients (n=227 in each group)...

BACKGROUND: Competence profiles are purposed to provide a blueprint in support to develop and/or benchmark the learning outcomes of undergraduate dental curricula. This study aims to investigate whether a competence profile as proposed by academic- and clinical experts is able to represent the real clinical reality. METHODS: A questionnaire was developed including questions about gender and age, perception about required competences, and educational organisation and was distributed among Flemish dentists via email and on paper during a symposium...

PURPOSE: Erosions and osteophytes are radiographic characteristics that are found in different stages of temporomandibular joint (TMJ) osteoarthritis. This study assessed the effectiveness of digital subtraction radiography (DSR) in diagnosing simulated osteophytes and erosions in the TMJ. MATERIALS AND METHODS: Five intact, dry human skulls were used to assess the effectiveness of DSR in detecting osteophytes. Four cortical bone chips of varying thicknesses (0...

PURPOSE: This article describes the use of rapid prototyping (RP) for diagnosis, planning, and execution of the reconstruction of hard and soft tissue in socket defects using immediate dentoalveolar restoration (IDR). SUMMARY: In cases of tissue loss in anterior dental areas, esthetic rehabilitation poses a major challenge with respect to treatment planning with the goal of long-term tissue maintenance. The IDR technique consists of immediate reconstruction in a single procedure of bone and soft tissue around implants placed immediately after extraction, and prosthetic rehabilitation...
