OBJECTIVES To determine the border level of brightness and contrast changes in order to prevent the loss of originality of the quantitative data on digital dental radiographs. METHODS After measuring the baseline mean grey values (MGVs) of a fixed region of interest on the alveolar bone and an aluminium step wedge, incremental brightness and contrast… (More)
Talon cusp is a rare phenomenon found on the lingual surfaces of anterior teeth. Five cases of talon cusp that were observed during routine clinical examination are described.
OBJECTIVE Our aim was to compare the Accu-I-Tomo (3DX), the Digora Optime image plate system and F-speed film in detecting chemically created apical lesions. METHODS Lesions were created by applying perchloric acid apical to extracted teeth in jaw specimens for 1, 1.5 or 2 h. After being repositioned, teeth were radiographed with Accu-I-Tomo limited cone… (More)
OBJECTIVE The calcified stylohyoid ligament and the elongated styloid process (SP) are identified radiographically, are associated with several syndromes and symptoms. The aim of this study was to classify and determine the incidence of different types of stylohyoid chain patterns in Turkish population to provide a guide for the dentist and maxillofacial… (More)
The aim of this study was to observe apical root surfaces of teeth with chronic periapical lesions. Five premolars and three molars with radiographically demonstrable periapical lesions were extracted and fixed in 2.5% phosphate-buffered glutaraldehyde solution for 9 days. The apical 3-mm portion of 17 roots was removed and prepared for scanning electron… (More)
The human stylohyoid chain calcification patterns (SCP) present considerable anatomic variability. This study was performed to investigate the calcification on SCP in the dentate and total edentulous population and its relation to mandibular protrusive movement. The study analyzed 1.234 SCP in digital panoramic radiographs of 617 subjects. The SCP were… (More)
OBJECTIVE To determine the performance of different processing solutions using an automatic processor for dental radiography. STUDY DESIGN One brand of dental X-ray film (Minimax, Chicago, IL, USA) was developed in an automatic processor using four different brands of processing solution: Megasan (MGS, Megasan, Ankara, Turkey), (HAC, Ankara, Turkey), Fuji… (More)
Several types of developmental anomaly of the teeth have been identified. In this article the authors describe three patients who presented with impacted teeth in the maxillary sinuses.
