Articaine versus Bupivacaine Anesthetic Effectiveness for Lower Teeth Extraction

by

An interesting article titled “A Comparative Evaluation of Anesthetic Effectiveness of 4% Articaine vs 0.5% Bupivacaine for Lower Molar Tooth Extraction” appears in Cureus in December 16, 2022, written by Tenglikar P, Manas A, Sahoo A, et al. (vol. 14, no. 12, pp. e32611). The article discusses the differences in the effectiveness of two common local anesthesia agents used in dentistry to control pain. The authors set out to explore the the effectiveness of 0.5% bupivacaine with 4% articaine in lower tooth extraction based on duration of anesthesia, onset, and pain perception along with observing blood pressure and heart rate. Today lidocaine (lignocaine) is extensively used as a local anesthestic agent in dentistry to control pain. Other anesthestic agents exists including bupivacaine and articaine. The authors conducted a randomized controlled study of patients having lower teeth extracted from June 2017 to October … Read more

Good News for Dental Phobes: Pain-Free and Needle-Free Dentistry May be Coming

by

Dental visits often evoke fear and anxiety, largely due to the dreaded needle and potential pain associated with procedures. But what if there was a way to experience pain-free and needle-free dentistry? Griffith University in Australia is currently trialing a revolutionary device called the Nuralyte that may offer pain and needle free dentistry the future. The reseaschers are developing a technology utilizing light to temporarily block nerve conduction in the teeth and jaw, mimicking the numbing effect of a traditional injection. One burst of light from the Nuralyte may provide 15 to 20 minutes of pain relief. Unlike X-rays, the energy in this light source does not alter DNA. Developed by tech start-up Dentroid, the Nuralyte holds immense potential to transform the dental industry. For individuals with dental anxiety or those who experience difficulty achieving complete numbness from injections, this … Read more

Comparing Injectable Anesthetics for Dentistry

by

A review articled carried out by the Cochrane Database of Systematic Reviews titled “Injectable local anaesthetic agents for dental anaesthesia (Review)” written by St. George et al. in 2018 (no. 7, art. no. CD006487) explored the success of local anesthetics used by dentists. Procedures in dentistry that use local anesthetics include endodontic treatment, placement of restorations, and extraction of teeth. The researchers wanted to determine if one form of anesthetic worked better than others in different scenarios. The researchers defined success for an anesthetic based on the absence of pain during the procedure. They sought out to also explore the speed of onset and duration of anesthesia as well as the systemic and local adverse effects. The researchers had a very thorough search that resulted in 123 studies which was later reduced down to 68 studies and compared 14 different … Read more

Comparison of Bupivacaine and Lidocaine for Wisdom Teeth Surgery

by

An interesting article titled “Comparison of anaesthetic regime in patients undergoing third molar extraction” written by McCarthy et al. appears in Oral Surgery in 2018 (vol. 11, pp. 33-40). The article seeks to explore the use of lidocaine and bupivacaine which are two different anesthetic agents for wisdom teeth removal to see if there is any difference on patient pain, preference, and satisfaction. The authors state that using local anesthesia for removing wisdom teeth when also using general anesthesia is still controversial. They thus designed a double blind split-mouth randomized clinical trial where both an anesthetic and control were used on a patient at the same time. The authors conducted the study in two parts. In the first part 52 patients were given 2% lidocaine with 1: 80,000 epinepherine on one side and nothing given on the other side. In … Read more

Is there a Difference in Complications following Wisdom Teeth Removal when using Local Anesthesia versus General Anesthesia?

by

An interesting article titled “Retrospective multivariable comparison for complications of third molar surgery performed under general versus local anaesthesia” written by Beteramia et al. appears in Oral Surgery in 2019 (vol. 12, pp. 96-103). The article seeks to explore if there is a difference in the amount of complications that occur during or after wisdom teeth surgery when using local anesthesia or when using general anesthesia. In the article the authors discuss complications that can happen during wisdom teeth removal including excessive bleeding, injury to the inferior alveolar and lingual nerves, damage to the adjacent second molar, alveolar bone fracture, and displacement of tooth fragments into fascial spaces and complications that can happen after wisdom teeth removal including alveolar osteitis (dry socket), a secondary infection, and hemorrhage. These complications are discussed more over at http://www.teethremoval.com/complications.html. The authors further discuss how … Read more
