It may be impossible to remove all bacteria from dental equipment

by

A few stories have appeared in articles in recent years where someone has gotten an infection at an oral surgeon or dentists office due to unsafe practices. See for example https://blog.teethremoval.com/unsafe-injection-practices-plaque-u-s-outpatient-facilities/. This has occurred when a lapse in following proper infection control practices has occurred. However, even when proper protocols are being followed at dental offices it may still be possible to come down with an infection (although rare). This is supported by a new study in the Journal Water Research titled “Efficacy of dental unit waterlines disinfectants on a polymicrobial biofilm.” The study reveals that disinfectants recommended by companies that manufacture dental unit water lines don’t actually shift all the bacteria in the lines, which means the water lines are never completely clean. The dental water lines are used by dentists to keep their dental equipment, which is always … Read more

Exploring Antibiotic Use with Lower Wisdom Teeth Surgery

by

An interesting article titled “Correlation of antibiotic prophylaxis and difficulty of extraction with post operative inflammatory complications in the lower third molar surgery” appears in the 2014 British Journal of Oral and Maxillofacial Surgery and written by J. Y. Lee and et al. (vol. 52, pp. 54-57). The article set out to investigate the correlation between antibiotic prophylaxis, difficulty of extraction, and postoperative complications of lower wisdom teeth. The authors say that indiscriminate antibiotic prophylaxis can lead to antimicrobial resistance and a shift in the microbial population. The authors performed a retrospective analysis of extraction of lower wisdom teeth performed at Korea University Guro Hospital over a two year time frame starting in January 2010. The authors only included cases in which cefditoren pivoxil was prescribed as an antibiotic. In addition, patients that were kept in a hospital due to postoperative complications were excluded from the … Read more

Exploring Mandibular Wisdom Teeth Roots after Coronectomy

by

Coronectomy involves the removal of part of the mandibular wisdom teeth but retention of the root. It is believed to cause less risk to the inferior alveolar nerve than extraction. An article on this topic titled “Histological evaluation of mandibular third molars roots retrieved after coronectomy,” appears in the 2015 British Journal of Oral and Maxilofacial Surgery and written by Vinod Patel and et. al (vol. 52, pp. 415-419). In the article the authors sought to find out the pulpal and periradicular status of retained roots of mandibular wisdom teeth and histologically evaluated coronectomy roots that were removed because of persistent symptoms. It is possible the roots had become infected. A total of 21 patients (with 26 roots) were included in their study with persistent symptoms after the roots had been retrieved. Of the 26 symptomatic roots, radiographic assessments showed coronectomy had been sufficient in … Read more

Bringing Rapid HIV Testing to Dentistry

by

An interesting study has been performed by the University of Sydney in 2014, looking at the possibility of using rapid HIV testing before dental surgery. The study assessed 521 Sydney based dental patients and their willingness to undergo rapid HIV testing in dental settings, their preference for HIV testing type, and their willingness to pay for the HIV test. More than 80% of the patients in the study were found to be willing to undergo rapid HIV testing before a dental procedure. The technology behind a rapid HIV test has been around for more than a decade but it not currently available in dental settings. The test can be done as a finger prick or a saliva swab. The results of the HIV test can be determined within 20 minutes. The Australian Federal government announced in July 2014, that they … Read more

Wisdom Teeth: Perspectives from the Military

by

In previous discussions on this blog such as Third Molar Morbidity Among Troops Deployed and elsewhere, a discussion has been made about whether or not wisdom teeth should be extracted in those involved in the armed forces. A new article from Hurlbert Field titled “Wisdom teeth: Should they stay or go” provides a perspective by Staff Sgt. Jeff Andrejcik, was written on December 3, 2013, and is located over at http://www2.hurlburt.af.mil/news/story.asp?id=123372876. The article is written by a special operations dentist who performs wisdom teeth extractions. He says he has removed over 300 wisdom teeth and once removed 8 in one patient. He says in the article that most people don’t have room for wisdom teeth and they grow in sideways and are not cleansable. Larkin discusses how pericoronitis can occur in patients who have wisdom teeth that erupt but not fully leaving … Read more
