Dentists Find Additional Bacteria Species Involved with Tooth Decay

by

An interesting article titled “Selenomonas sputigena acts as a pathobiont mediating spatial structure and biofilm virulence in early childhood caries,” written by Hunyong Cho and et. al. appears in Nature Communications (vol. 14, no. 1, 2023). The article seeks to study if other bacteria besides Streptococcus mutans are involved with tooth decay and cavities in children, also known as dental caries. Prior to the study it was believed that S. mutans and other acid-making bacteria are adequately removed by teeth-brushing and oral care, and this creates a protective biofilm, or plaque, on teeth. If the plaque is left in place for too long, bacteria consumes sugars from food and drinks and coverts them to acidsm which erode the enamel of affected teeth, in time creating cavities. The article investigated the role of Selenomonas sputigena (S. sputigena) in early cavities in children. S. … Read more

How dentists can navigate ethical treatment decisions for patients

by

An interesting article titled “How to manage the principal-agent problem in dentistry,” appears in the June 2022 edition of the Journal of the American Dental Association (JADA) written by Ben Balev (no. 153, issue 6, pp. 588-589). The article discusses the principal-agent problem, in which the dentist operates as the agent for the patient who is the principal and there is an imbalance of power between the patient and the dentist in decision making. In the dentist-patient relationship, the dentist has specialized knowledge that the patient lacks, and the patient seeks to make up for their lack of knowledge by having the dentist help in oral health decisions. Such a relationship requires that the patient trusts that the dentist functions in their best interest. However, sometime the patient questions the dentists motives behind their treament recommendations. The patient may wonder … Read more

An interesting article titled “Computer-controlled Intraligamentary local anaesthesia in extraction of mandibular primary molars: randomised controlled clinical trial,” appears in the 2022 edition of BMC Oral Health written by Rodaina H. Helmy and et. al. (vol 22, no. 194, pp. 1-10). The article seeks to explore the pain experience when using a computer controlled anethesia injection while extracting lower primary molars in children. To explore the pain experiences of children, 50 healthy children between the ages of 5 and 7, with 29 females, and 21 males, who needed a lower primary molar extractioned were included in the trial. The parents of the children had to consent to inclusion in the trial. Any child who had teeth that showed signs of mobility, acute pathosis, ankylosis, or root resorption affecting more than a third of the root were excluded from the study. … Read more
