How Important Is Gutta Percha?

To be sure right size of gutta percha is choose in order to fill whole length of root canal except 2mm at the apex

Improper use of abrasives can lead to roughening and reduction of the tooth and restorative materials. The dental hygienist should be able to distinguish between tooth structures, and restorative materials and must use the proper procedure for finishing, polishing, or cleaning each surface. It is also imperative for the clinician to understand the relative hardness of various intraoral materials and

Consequently, I was involved in the mechanical testing of bioceramic endodontic materials with regards to their physical properties and hydration behavior. Also, I am participating in an ongoing Micro-CT study to evaluate the quality of root filling using different filling techniques and sealers.

With all these results, many variations among materials, operators, and patients can contribute to these clinical failures. Therefore, further clinical research and studies are necessary to evaluate the performance of the restorative materials and to determine the factors related to the failures as many conditions cannot be reproduced in the labatory. In previous studies, evaluations of the studies showed that in a period of 5-12 years, the success was 85 to 98 percent. In the longest follow-up mentioned by Dr.

The success of endodontic therapy depends on complete cleaning and shaping of the root canal, disinfection of the canal and obturation of the canal space. However, despite the use of aseptic techniques during these procedures, reinfection may occur.[1] One of the possible explanations may be the use of contaminated gutta-percha.1

When a tooth is badly decayed or infected a root canal treatment is used to repair and save the tooth.

Initially, for the purpose of denture base, vulcanized rubber (vulcanite) has been in use. It was introduced in the year 1855 to the field of dentistry (Tandon et al., 2010). However, there were several issues faced with respect to its fabrication as well as the aesthetics. With this, the year 1937 saw the advent of PMMA which replaced vulcanite as it had enhanced properties (Machado et al., 2007). It also was less expensive than vulcanite and aesthetically more pleasing. From then on, PMMA has been in use. Recently, additional polymers such as nylons, vinyl acrylic and light activated urethane dimethymethcarylate have been evaluated for use as denture base materials (Diaz-Arnold et al., 2008). Even if these materials do exhibit very capable properties, none of them have been deemed superior to PMMA. However, clinical studies (Ray et al., 2014; Dhiman & Chowdhury, 2009) have reported midline fractures to be a common problem in maxillary complete dentures due to fatigue

Impregum was used for the second impression and was sent to the lab for a bruxZir crown. This material had also been used for years by Dr. Spencer due to its flexibility and pleasant taste. Dr. Spencer had tried different products in the past, however, he found these specific materials to be more effective. The bruxZir crown is a more esthetic choice and was selected for this specific patient based on grinding habits. The other procedure I observed was a porcelain-fused-to-metal (PFM) crown placement using Cavidry, Carboxylate cement, and Durelon. Cavidry is a cleaning agent used for rapid drying, degreasing, and cleaning the area before a crown placement. Carboxylate cement and Durelon are mixed together to create a cement that is the most effective for porcelain-fused-to-metal crowns or gold crowns. The Carboxylate cements and Durelon were selected by the dentist due to its desirable retention of restorations, easy to use, and is inexpensive. The dentist also selected the PFM crown because it is a noble metal that is least likely to break. The office manager explained that a specific crown is selected based on insurance, esthetic purposes, and according to patient’s oral habits.

Dentists in the United Kingdom are one of the most likely in the world to be exposed to dento-legal issues, and fixed partial dentures are among the most common dental treatment that could lead to complaint (Briggs et al. 2012). We must be able to differentiate between production failure and function failure. Production failure where the prosthesis fail early after cementation which could indicate a problem in diagnosis (Cronström et al. 1998). Fixed partial dentures are an expensive treatment that should not go

The materials used for the temporary crown prep consisted of Centrix, Jet Tooth Shade Powder and Jet Liquid, Temp-Bond, and Impregum. The Centrix impression material was used in this appointment as

Endodontically-treated teeth restorations are still a big challenge in Dentistry. There is a need to properly replace

Metallic Crown: Less tooth structure needs to be removed and tooth wear is minimal. The

Root canal therapy is designed to be a simple, pain-free procedure to help eliminate discomfort caused by infection. We use topical and local anesthetics to numb the tooth and connected nerve before beginning the procedure. We also offer sedation dentistry to those who need a little extra help feeling at ease. The two types we offer are nitrous oxide and oral conscious sedation. Learn more about how we can provide you with pain-free, stress-free dentistry here.

The ‎materials are either resin based or glassionomer based sealants. Resin composite sealant ‎show high retention rate to enamel and high mechanical properties compared to ‎glassionomer (4), however its success is compromised when the operative field cannot be ‎isolated as in permanent molars that are not fully erupted or primary molars in children. In ‎such clinical situation, glassionomer is highly recommended (5). It does not require ‎etching procedures prior to application which decrease the moisture sensitivity. in ‎addition to the anticariogenic properties, which resulted in to great decrease in caries ‎incidence even after the sealant is disappeared

The key factor for the success of root canal treatment mainly depends on the complete elimination of microbes and their byproducts present in the root canal system. Effective elimination of bacteria can be achieved by combining a proper mechanical preparation followed by irrigation using antimicrobial root canal irrigant and placement of intra canal medicament. Root canal irrigants and antimicrobial medications are therefore important for elimination of these bacteria and for disinfection of the root canal system as bacteria located in areas such as isthmuses, ramifications, deltas, irregularities and dentinal tubules will not be eliminated by mechanical means alone.1
