Abstract

A dental fracture or cracked tooth is a break or crack of a tooth fragment which is usually caused by traumatic injuries or attack. Traumatic injuries to the tooth can affect the pulp so that the tooth becomes necrosis (nonvital). Root treatment is one of the treatments for pulp disease by removal of the pulp from the root canal and filling the canal with obturation material. The goal is to prevent transmission of the pulp to the periapical tissue, or if it has occurred, to alter or return the periapical tissue to its normal state. This case report discusses root canal treatment of a nonvital tooth in a 31 years old female patient with fracture tooth. The treatment plan is root canal treatment which consists of three main stages that are biomechanical preparation of the root canal, root sterilization with calcium hydroxide, and obturation. Obturation of the root canal using lateral condensation technique with gutta percha material and endomethasone sealer. The success of root treatment requires knowledge of the root canal and the quality of obturation as well as the final restoration.

Abstract

Purpose: to determine fracture resistance differences between smooth type fiber reinforced composite post and serrated types.Methodology: the design of research is post test only control group design. The sample were 32 extracted mandibullary premolars treated endodontically crown down method with gutta percha and resin sealer. The tooth after root canal treatment is continued with the preparation of the post using precission drill. The samples divided into two group based: A. smooth type FRC post, B. serrated type FRC post. FracturSamples were loaded to failure with a Universal Testing Machine. Results: there was a fracture resistance difference between smooth type of FRC post and serrated. Fiber reinforced composite type serrated is more resistance to fracture than FRC type smooth.

Abstract

Background: Endodontic treated teeth are more susceptible to fracture. Correct restoration can minimize fracture risk, for example crown and post-core systems. Based on its manufacturing, Fiber Reinforced Composite (FRC) Post was divided into prefabricated and fabricated. The objective of this study was to evaluate the differences of fracture resistance between Prefabricated and Fabricated FRC Post systems on different post canal width. Method: The samples of this study were 28 premolars that were cut with 15 mm in length. The samples were treated with conventional endodontic method using gutta percha and resin sealer. The samples were divided into two groups and two sub-groups. The first two group was based on canal width consisting of 14 teeth each group with two different canal width (1.4 mm and 2.1 mm). Then, the first group was divided again into two subgroups based on the dowel use (Prefabricated post and Fabricated Post). Universal Testing machine was used to test the samples resistance. Result: This research showed that there were differences in fracture resistance on different post canal width. However, there were no fracture resistance differences between prefabricated post and fabricated post.
