Local Anesthesia Leads to Temporal Muscle Ossification

by

An interesting article titled “Traumatic myositis ossificans of the temporalmuscle after dental local anesthesia,” written by S.B. Helland and T.Ø. Pedersen appears in Clinical Case Reports (no. 11, pp. e7410, 2023). The article describes a case of a thirty year old woman who developed ossification of the temporal muscle attachment after local trauma during dental treatment which prevent her from opening her mouth. The thirty year old woman presented four months after having had a root canal treatment of a maxillary premolar tooth when local anesthesia was given near the right temporal muscle attachment. At the time she noted a sharp pain right after the injection was given. He also experienced persistent limited mouth opening after the dental treatment. Computer tomography was taken when the woman presented four months later which showed a bony growth roughly 3cm in length extending … Read more

Antimicrobial Gel To Improve Root Canal Procedures

by

The American Association of Endodontists estimates that more than 15 million root canals are done each year. During the procedure, the tooth’s pulp and nerve are removed before the tooth is cleaned and sealed. In some cases bacteria, viruses, or yeasts contaminate the tooth which leads to additional follow up dental work having to be performed such as an additional root canal. Researchers at the Indiana University School of Dentistry have developed an injectable antimicrobial gel that could disinfect a tooth during a root canal procedure. The gel has advantages over traditional medications used as antibacterial agents, including calcium hydroxide. The gel offers extended and significantly longer residual antibacterial properties. The gel is biocompatible and contains a low concentration of antimicrobial elements. The researchers feel that creating an antimicrobial space is important during clinical regenerative endodontic procedures. The gel provides sustained antimicrobial properties even when it is … Read more

Nanodiamonds to Help With Root Canal Recovery

by

Researchers at UCLA found in a clinical trial that nanodiamonds protected disinfected root canals after the nerve and pulp were removed. This result may help people who undergo root canals as it could help prevent infection after treatment. Specifically combining nanodiamonds with gutta percha, a material used to fill disinfected root canals, may enhance the gutta percha’s protective properties. Nanodiamonds are tiny particles made of carbon and are very very small. Nanodiamonds have previously been explored to deliver drugs and serve as imaging agents. Protecting disinfected root canals is a delicate process. Dentists use gutta percha to block bacteria from infiltrating the tooth, but it can break during the procedure or create pockets of space for bacteria to infiltrate. The researchers tested nanodiamond-embedded gutta percha (NDGP) in three people who undergoing root canal procedures. These tests demonstrated the implanted material NDGP … Read more

Prefabricated blood vessels may revolutionize root canals

by

Root canals are used to save a tooth that has become infected or decayed, with over 15 million performed each year in the U.S.. However, this procedure can cause teeth to become to become brittle and susceptible to fracture over time. The procedure involves removing infected dental tissues and replacing them with synthetic biomaterials covered by a protective crown. Now researchers in Portland, Oregon, have developed a process by which they can engineer new blood vessels in teeth, creating better long-term outcomes. By removing the tooth’s blood and nerve supply it is without an biological response. Then can cause the tooth to be lost and a need of dentures or implants. The researchers used a 3D printing-inspired process, which was based on their previous work fabricating artificial capillaries, to create blood vessels in the lab. They placed a fiber mold made … Read more

Washington Dentist Troubles

by

Recently, a few articles appeared on DrBicuspid talking about Washington dentists. One of the dentists is a Washington state dentist, the other is a Washington D.C. dentist. The first article talks about how a now retired Washington state dentist must pay $35 million to 29 former patients. The reason for this is because the court determined that the former dentist had performed numerous unnecessary root canals over a long period of time.   The article discusses how the retired dentist performed over 2,000 root canals on about 500 patients over a five year span several years ago. The dentist who purchased the retired dentists practice said that a lot of failing root canals and railing crowns were being noticed by the patients coming in. The court in this case found that the dentist was negligent, failed to obtain informed consent from … Read more
