Transient Bradycardia during Dental Anesthesia: Risk Factors and Mechanisms

Dental procedures are generally safe; however, transient bradycardia (TB), a temporary slowing of the heart rate, can sometimes occur during local anesthesia administration under sedation. This phenomenon, often linked to the trigeminal cardiac reflex (TCR), can occur during the administration of local anesthesia, particularly in patients undergoing sedation. Understanding the Mechanisms The TCR is a physiological response triggered by stimulation of the trigeminal nerve, which innervates the face and oral cavity. This stimulation can lead to a cascade of events, including a sudden decrease in heart rate and blood pressure, as well as other autonomic responses. Identifying Risk Factors A recent prospective study identified several key risk factors associated with the occurrence of TB during dental anesthesia: Study Findings A study appearing in BMC Oral Health titled “Transient bradycardia during local anaesthesia to the oral cavity under intravenous sedation and … Read more

Volatile Organic Compounds (VOCs) and Periodontitis: Is There a Connection?

Periodontitis is a common gum disease that affects millions of people around the world. It is caused by inflammation of the gums, which can lead to tooth loss if left untreated. While the main cause of periodontitis is poor oral hygiene, recent studies suggest that exposure to environmental pollutants may also play a role. Volatile organic compounds (VOCs) are a large group of chemicals that are found in many everyday products, such as paint, cleaning supplies, and air fresheners. VOCs can also be released from industrial emissions and traffic fumes. Exposure to VOCs has been linked to a number of health problems, including respiratory problems, cancer, and kidney disease. A recent study published in the BMC Oral Health (titled “Mediating role of systemic inflammation in the association between volatile organic compounds exposure and periodontitis: NHANES 2011–2014”, written by Zhida Dai and … Read more

Less sleep may increase cavities risk

An interesting article titled “Association between sleep duration and dental caries in a nationally representative U.S. population” written by Abdullah Alawady and et. al. appears in BMC Oral Health (vol. 23, Article number 497, 2023). The article seeks to establish the relationship between sleep duration and dental caries (cavities). The authors used data from the 2017-2018 U.S. National Health and Nutrition Examination Survey to explore 5,205 patients age 16 and older who completed a dental exam and sleep questionnaire. They performed regression analyses to reveal a statistically significant negative relationship between caries and sleep duration. It was found that those who have an average sleep duration of seven or more hours per night were less likely to have caries compared to people who slept less than seven hours (95% confidence interval 0.33 to 0.82; p < 0.05). Specifically 88.9% (4630/5205) of the … Read more

Wisdom Teeth: A Clash of Perspectives Between Orthodontists and Oral Surgeons

Wisdom teeth, or third molars, often erupt in late adolescence or early adulthood. While some erupt smoothly, many become impacted, meaning they fail to fully emerge through the gums. This can lead to various complications, including pain, infection, and damage to adjacent teeth. The management of asymptomatic impacted wisdom teeth is a subject of ongoing debate among dental professionals. While there’s consensus on extracting symptomatic teeth, the decision to remove asymptomatic ones remains contentious. A new study titled Prophylactic third molar removal: are oral surgeons and orthodontists aligned in preventive approaches (written by Ipek Necla Guldiken and et. al, BMC Oral Health, 24, Article number: 1072, 2024) aimed to investigate the perspectives of orthodontists and oral surgeons regarding the indications for prophylactic extraction of asymptomatic wisdom teeth. Methods: A web-based survey was conducted among 127 orthodontists and oral surgeons in Turkey. Participants … Read more

Social Media’s Shadow: How Online Content Can Increase Anxiety Before Wisdom Teeth Surgery

Wisdom teeth removal is a common surgical procedure, yet many patients experience significant anxiety leading up to the day. While social media can be a valuable resource for information and support, a recent study published in the Journal of Oral and Maxillofacial Surgery (written by Ufuk Tatli and Tahayasin Kalkan, titled Does Social Media Increase Perioperative Anxiety in Patients Undergoing Impacted Third Molar Surgery?, 2024) suggests that browsing online content related to the surgery can inadvertently increase preoperative anxiety. Researchers at Marquette University School of Dentistry investigated this phenomenon by examining the anxiety levels of 162 patients scheduled for wisdom teeth extraction. They divided participants into two groups: those who actively sought out and viewed social media content related to the surgery and those who avoided such exposure. The study employed standardized anxiety assessments to measure the impact of social media consumption … Read more
