Listen to Music Before Dental Cleaning to Reduce Anxiety

by

An interesting article titled “Effects of Music Listening on Pre-treatment Anxiety and Stress Levels in a Dental Hygiene Recall Population” written by Thoma et al. appears in the International Journal of Behavioral Medicine (vol. 22, no. 4, pp. 498-505). The article discusses how waiting for a medical procedure can provoke anxiety in patients and lead to stress. In the article the authors perform a study to explore if patients waiting for a dental cleaning can have their anxiety reduced by listening to music. The authors were motivated to perform their study because previous studies have shown that listening to music can reduce anxiety and stress. Other studies in hospital patients has also shown that listening to music prior to surgery reduces anxiety and can do so just as effectively if not better than pharmacological options like benzodiazepines. Furthermore, these prior … Read more

Blood tests to detect dental fear

by

An interesting article titled “The impact of dental treatment and age on salivary cortisol and alpha-amylase levels of patients with varying degrees of dental anxiety” written by AlMaummar, AlThabit and Pani appears in BMC Oral Health in 2019 (19:211). The article discusses the use of blood tests to attempt to determine which children might be more susceptible to dental fear. Dental fear has been discussed before on this site such as in the post Dental Anxiety and Fear: Impact on Oral Health. The study included 151 children who were treated at the dental clinics of King Abdulaziz Medical City and Riyadh Colleges of Dentistry and Pharmacy in Riyadh. Each of the children had behavior screening done using a Frankl behavior rating scale and a Children’s Fear Survey Schedule children’s subscale to assess dental fear. Based on answers to the behavior … Read more

Prior gum disease increases cancer risk

by

Researchers have found that postmenopausal women who had prior gum disease have a higher risk of cancer. The study was conducted by researchers at the University at Buffalo. The study is the first to find an association between periodontal disease and gallbladder cancer risk in women or men. The study also provided useful information on a number of cancer-specific sites. The study included 65,869 postmenopausal women who were part of the Women’s Health Initiative, an ongoing national prospective study designed to investigate factors affecting disease and death risk in older U.S. women. Most women were non-Hispanic and the average age was 68. Participants were asked “has a dentist or dental hygienist ever told you that you had periodontal or gum disease?” Those women who had a history of gum disease had a 14% increased risk of overall cancer. A total of 7,149 … 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

More Oral Pathogens and Less Bacterial Diversity in the Mouth Could Precede Stomach Cancer

by

Researchers at the New York University College of Dentistry (NYU Dentistry) and New York University School of Medicine have found that elevated pathogen colonization and a lack of bacterial diversity in the mouth were identified in people with precancerous lesions that could precede stomach cancer. This work provides evidence that the increase in pathogens associated with periodontal disease (gum disease) could contribute to the development of precancerous lesions of stomach cancer. The specific finding of the study is that poor oral health is associated with an increased risk of precancerous lesions of stomach cancer. The potential of developing periodontal disease is one of the main risks of keeping wisdom teeth as discussed over at http://www.teethremoval.com/risks_of_keeping_wisdom_teeth.html. The American Cancer Society estimates that 26,370 new cases of stomach or gastric cancer were diagnosed in 2016, and this lead to 10,703 deaths.  Evidence suggests that chronic … Read more
