DİŞ HEKİMLİĞİNDE DİJİTAL RADYOGRAFİ [Digital Radiography in Dentistry]

ÖZET Bilgisayar teknolojisindeki gelişmelerle birlikte tek seferde görüntü elde edilmesi, görüntünün iyileştirilmesi, kalitesinin arttırılması, muhafaza edilmesi, yeniden kazanılması, dijital formatta görüntülerin uzak bölgelere aktarılması sağlanmıştır. Diş hekimliğinde yarım yüzyıla yakın geçmişi olan dijital radyografi sistemlerin gelişimi günümüzde halen devam etmektedir. Buna paralel olarak hekimler arasında kullanımı da gün geçtikçe yaygınlaşmaktadır. Bu derlemenin amacı, diş hekimliğinde kullanılan dijital radyografinin avantaj ve dezavantajları, diş hekimliği pratiğinde kullanım alanları hakkında bilgi vermektir.

Development of digital radiography systems with a history of almost half century in dentistry still goes on today. In parallel with, tenancy to this systems among dentists are becoming prevalent by the day. The purpose of this review is to give information about advantages and disadvantages of digital radiography and uses of in dental practice.

Is there a relationship between the presence of ponticulus posticus and elongated styloid process?

This study aimed to determine if there is a possible relationship concerning the presence of ponticulus posticus (PP) in patients with elongated styloid process (ESP) on three-dimensional cone beam computed tomography (CBCT) images. The presence or absence of the PP (whether partial or complete) was determined and noted as a positive or negative finding. Then, the patients with PP were evaluated for ESP. For this purpose, 3-D CBCT scanning digital images of 542 patients having ESP (247 males and 295 females) were examined retrospectively. There was a significant relationship between the presence of PP and ESP (P=.03). The results of this study suggest that there is a significant correlation between the presence of PP and ESP. To our knowledge, this is the first study investigating the relationship between the two disorders in the literature. (C) 2015 Elsevier Inc. All rights reserved

Evaluation of technical quality and periapical health of root-filled teeth by using cone-beam CT

Objective This study aimed to assess the quality of root fillings, coronal restorations, complications of all root-filled teeth and their association with apical periodontitis (AP) detected by cone-beam computed tomography (CBCT) images from an adult Turkish subpopulation. Material and Methods The sample for this study consisted of 242 patients (aging from 15 to 72 years) with 522 endodontically treated teeth that were assessed for technical quality of the root canal filling and periapical status of the teeth. Additionally, the apical status of each root-filled tooth was assessed according to the gender, dental arch, tooth type and age classification, undetected canals, instrument fracture, root fracture, apical resorption, apical lesion, furcation lesion and type and quality of the coronal structure. Statistical analysis was performed using percentages and chi-square test. Results The success rate of the root canal treatment was of 54.4%. The success rates of adequate and inadequate root canal treatment were not significantly different (p>;0.05). Apical periodontitis was found in 228 (45.6%) teeth treated for root canals. Higher prevalence of AP was found in patients aging from 20 to 29 years [64 (27%) teeth] and in anterior (canines and incisors) teeth [97 (41%) teeth]. Conclusions The technical quality of root canal filling performed by dental practitioners in a Turkish subpopulation was consistent with a high prevalence of AP. The probable reasons for this failure are multifactorial, and there may be a need for improved undergraduate education and postgraduate courses to improve the clinical skills of dental practitioners in endodontics
