Exploring the Risk Factors for Injury To Nerves During Wisdom Teeth Removal

by

An interesting article titled “Risk Factors for Permanent Injury of Inferior Alveolar and Lingual Nerves During Third Molar Surgery,” appears in The Journal of Oral and Maxillofacial Surgery, vol. 72, issue 12, and written by Edward Nguyen and et al. The article assesses the incidence of and risk factors for permanent neurologic injuries to the inferior alveolar nerve (IAN) or lingual nerve (LN) after wisdom teeth removal. The article states “It has been well documented in the literature that the risk factors for IAN and LN injuries include increasing age, unerupted teeth, deep impaction, distoangular impaction, irregular root morphology, lack of clinician experience, lingual flap and retraction, and radiographic signs of proximity of the third molar to the IAN canal. The main forms of altered sensation that can occur include paraesthesia, anesthesia, or dysesthesia, which may be temporary or permanent. The … Read more

Can Graphene Be Used to Treat Gum Disease and Fight Cavities?

by

When bacteria invade the mouth dental disease can form. This can lead to tooth decay or gum disease. Traditionally, antibiotics are prescribed to kill the bacteria if it is found. However, antibiotic resistance has been an issue in recent years where the antibiotics no longer work as effectively to kill the bacteria. Thus new methods to eliminate bacteria are need. Scientists have discovered a material called graphene oxide is effective at eliminating this type of bacteria even if it has developed antibiotic resistance.  Previous studies have shown that graphene oxide which are carbon nanosheets studded with oxygen groups, is a promising material in biomedical applications. Graphene oxide can inhibit the growth of some bacterial strains with minimal harm to mammalian cells. Researchers were interested to see if graphene oxide is effective at elminating bacteria responsible for dental disease. They tested … Read more

Wisdom Teeth Stem Cells Could be Used For The Eye

by

A new interesting study has shown that wisdom teeth stem cells could be turned into cells of the eye’s cornea. The stem cells could one day be used to repair cornea scaring due to infection or injury. Thus wisdom teeth stem cells could play a role in helping to treat corneal blindness which affects millions of people in the world. It is typically treated with transplants of donor corneas. Of course, with any transplants, shortages can occur and rejection of donor tissue can occur. This can result in permanent vision loss. Using one patient’s own stem cells from their wisdom teeth would avoid these issues. The research was conducted in association with the University of Pittsburgh. Their Department of Opthalmology showed that stem cells of dental pulp obtained from a wisdom tooth extraction could be turned into corneal stromal cells … Read more

Case Reports Serve a Place in Dentistry

by

An interesting article titled “CASE REPORTS HAILED” appears in JADA in September 2014, written by Enihomo Obadan, Elsbeth Kalenderian, and Rachel B. Ramoni. The article discusses an article in an earlier 2014 JADA article that featured an interesting case report. The authors state “Almost becoming a lost art in the biomedical literature, case reports still hold tremendous opportunities for learning in dentistry. In addition to the obvious learning potential for the individual dental professional, the entire professional body advances in giant strides when there is cross-organizational learning among dental clinics through information sharing.” The authors then discuss how adverse dental events being reported by dentists would help make dental treatments safer for all. The authors feels this helps promote a culture of safety, as long as there is no fear of retribution when the report occurs by the dentists. The … Read more

How to Address a Patient who Had an Interrupted Treatment Plan

by

An interesting article titled “Following up with a patient whose treatment has been interrupted” appears in the November 2014, JADA, and written by Michael H. Halasz. The article discusses a patient who received a complex treatment from a military dentist. The treatment started but because of deployment of a large number of troops in Iraq the treatment was interrupted so that the dentists could attend to other troops. The article addresses if the patient was abandoned during this time. The American Dental Association Principles of Ethics and Code of Professional Conduct states “Once a dentist has undertaken a course of treatment, the dentist should not discontinue that treatment without giving the patient adequate notice and the opportunity to obtain the services of another dentist. Care should be taken that the patient’s oral health is not jeopardized in the process.” The … Read more
