BACKGROUND To compare the quality of calcium hydroxide paste fillings performed by three different techniques. MATERIAL AND METHODS Sixty extracted maxillary central incisors, with previous root canal treatment, were decoronated and the gutta-percha was completely removed from the root canals. Subsequently, the canals were filled with a calcium hydroxide-based paste composed of calcium hydrox...

AIM To investigate the technical quality of nonsurgical root canal treatment performed by endodontists in Melbourne, Australia. METHODOLOGY Clinical and radiographic records of 100 sequential nonsurgical patients were obtained from each of six endodontists working in private practice. The following variables were analysed: proximity of root filling to radiographic apex; homogeneity and radiod...

introduction: this study was carried out to evaluate the bacterial leakage of root canal fillings when cavity varnish containing 5% fluoride (duraflur) was used as root canal sealer. methods and materials: root canals of 88 straight single-rooted teeth were prepared. eighty teeth were randomly divided into 3 experimental groups ( n =20) and two positive and negative control groups of ten each. ...

background and aim: the main goal of endodontic treatments is eliminating the etiologic factors of pulpal and periapical diseases as well as maintaining this condition via providing a hermetic seal between periodontium and root canal system. if these were not possible through orthograde approach, periradicular surgery and root-end filling are indicated. review of literature: different materials...

introduction: leakage of the root canal system is an importent consideration when placing an intracanal medicament. the aim of this in vitro study was to compare the effect of calcium hydroxide and 1% chlorhexidine gel as intracanal medicaments on tooth apical seal. materials and methods: seventy extracted, single-rooted maxillary anterior teeth were divided into the three experimental groups (...

The aim of this study was to evaluate the effectiveness of gutta-percha and Resilon in filling lateral root canals by using the Obtura II system. Root canals of artificial teeth were prepared using a standard protocol, and lateral canals were made in three thirds of the root canal. The root canals were filled with either Obtura gutta-percha (OB), Endo-points flow gutta-percha (ED), or Resilon (...

The aim of this systematic review was to determine whether there is a root canal filling for deciduous teeth equally or more effective than zinc oxide-eugenol cement (ZOE). Six clinical trials selected for inclusion were independently reviewed by two researchers. Only two showed statistically significant different success rates between the test and the control groups. One found that an iodoform...

The purpose of this study is to cluster all of the oral and dental health centers that have a wide range of service and rate (119 in 2009, 117 in 2010) in 7 regions of Turkey apart from the dental hospitals under the Ministry of Health according to the services they offer and determine the service groups which affect the clustering. The second aim which the study has focused on is to determine ...
