2. Root filling bond strength using reciprocating file-matched single-cones with different sealers
Abstract The aim of the present study was to evaluate the bond strength (BS) of root canal fillings to root dentin using the reciprocating file-matched single-cone or lateral compaction techniques with resin-based and calcium-silicate-based sealers. Maxillary canine roots were prepared and filled using one of the following approaches: Reciproc R40 file and R

3. 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 f

4. Comparison of different retreatment techniques and root canal sealers: a scanning electron microscopic study
The aim of this study was to evaluate the effectiveness of two retreatment techniques, in terms of the operating time and scanning electron microscopy (SEM) results, in removing three different root canal sealers from root canals that were previously filled with gutta-percha. Sixty extracted single-rooted human premolars were divided into three groups and fi

5. Influence of root canal sealer on the radiographic appearance of filling voids in maxillary single-rooted teeth
OBJECTIVE: This study compared the influence of three epoxy resin-based sealers with distinct radiopacities on the observers' ability to detect root canal filling voids during radiographic analysis. MATERIAL AND METHODS: The root canals of 48 extracted maxillary canines were prepared and divided into three groups. Each group was laterally condensed with one

6. Tissue reaction to Endométhasone sealer in root canal fillings short of or beyond the apical foramen
OBJECTIVE: This study evaluated the response of periapical tissues to the endodontic sealer Endométhasone in root canal fillings short of or beyond the apical foramen. MATERIAL AND METHODS: Twenty root canals of premolars and incisors of 2 mongrel dogs were used. After coronal access and pulp extirpation, the canals were instrumented up to a size 55 K-file

7. Apical sealing of root canal fillings performed with five different endodontic sealers: analysis by fluid filtration
OBJECTIVES: To evaluate the sealing ability of five root canal sealers, including two experimental cements (MBP and MTA-Obtura) using the fluid filtration method. MATERIAL AND METHODS: Teeth were divided into 5 study groups: G1-AH Plus; G2-Acroseal; G3Sealapex; G4-MBP; G5-MTA-Obtura; and two controls. Chemical-mechanical preparation was performed with ProFil

8. Effectiveness of gutta-percha and Resilon in filling lateral root canals using the Obtura II system
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

9. Avaliação da qualidade das obturações endodônticas realizadas por estudantes de graduação = Evaluation of the quality of the root canal fillings accomplished by undergraduate students / Evaluation of the quality of the root canal fillings accomplished by undergraduate students
O objetivo deste estudo foi avaliar a qualidade das obturações dos canais radiculares realizados por estudantes de graduação em Odontologia. A amostra foi constituída por 156 canais radiculares obturados e analisados através de radiografias periapicais. Compuseram a análise dentes uni e multirradiculares com tratamento endodôntico concluído há pelo

10. Radiographic analysis of root canal fillings: influence of two sealers on the perception of voids
O propósito deste estudo ex vivo foi investigar se dois cimentos obturadores de fórmulas diferentes influenciariam a percepção radiográfica de obturações de canais radiculares. Os canais radiculares de 48 caninos superiores extraídos foram preparados e divididos em 3 grupos. Em cada grupo os canais foram preenchidos através da condensação lateral

11. Radiographic quality of root canal fillings performed in a postgraduate program in endodontics
O objetivo deste estudo foi avaliar o padrão de qualidade de 1.347 obturações de canais radiculares realizadas por estudantes de pós-graduação em endodontia, conforme 3 parâmetros radiográficos. Os parâmetros de qualidade analisados incluíram limite apical (LA), conicidade (CO) e homogeneidade (HO), os quais receberam escores E2 (padrão ideal), E1

12. Influência da radiopacidade dos materiais obturadores sobre a sensibilidade, especificidade e confiabilidade da análise radiográfica de obturações endodônticas / Influence of root canal sealing materials radiopacity on sensitivity, specificity, and reliability of radiographic root canal fillings exam
The aim of this study was to investigate the effect of different radiopaque sealers in the sensitivity, specificity and realiability of radiographic root canal filling exam. After radiopacity distinction of root canal sealing materials, a total of 80 extracted single-rooted upper canines had their canals prepared with classic technique before being divided i
