Less sleep may increase cavities risk

by

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

Understanding Dental Crowns: A Comprehensive Guide

by

A dental crown is a versatile solution for restoring damaged or decayed teeth, enhancing their strength, function, and appearance. With various options available, selecting the right dental crown depends on factors like durability, aesthetics, and cost. This article explores the different types of dental crowns and their unique benefits to help you make an informed decision. Types of Dental Crowns 1. Porcelain-Fused-to-Metal (PFM) Crowns Porcelain-fused-to-metal crowns combine the durability of metal with the natural appearance of porcelain. These crowns have a metal core for strength, while the outer layer mimics the color and texture of natural teeth. PFM crowns are commonly used for both front and back teeth, offering a balance between aesthetics and functionality. Pros: Cons: 2. All-Ceramic or All-Porcelain Crowns All-ceramic or all-porcelain crowns are crafted entirely from porcelain or ceramic materials, making them ideal for patients seeking … Read more

Fluoridated Water: Still a Valuable Tool, but Benefits May Be Diminishing

by

Tooth decay remains a significant public health concern worldwide. For decades, adding fluoride to community water supplies (CWF) has been a cornerstone of dental health strategies. However, a recent Cochrane review (titled “Water fluoridation for the prevention of dental caries” written by Tanya Walsh and et. al., 2024) suggests that the benefits of CWF may be less pronounced today than in the past, particularly in developed countries where fluoride toothpaste is widely used. The Review’s Findings: The review analyzed 157 studies comparing tooth decay in children living with fluoridated water and those without. Why the Change? The authors attribute this shift to the widespread use of fluoride toothpaste. With fluoride readily available through oral hygiene products, the incremental benefit of CWF may be less pronounced in modern populations. Important Considerations: The review emphasizes that these findings do not negate the … Read more

Tooth loss associated with brain shrinkage

by

An interesting article titled “Associations of Dental Health With the Progression of Hippocampal Atrophy in Community-Dwelling Individuals: The Ohasama Study,” written by Satoshi Yamaguchi and et. al. appears in Neurology, published on Juy 5, 2023. The article sought to explore associations between the number of teeth present and hippocampal atrophy older patients 55 years and older in a longitudinal study. The hippocampus is part of the brain that is important for learning and memory. With Alzheimer’s disease, atrophy of the hippocampus is a common feature but other factors, such as periodontitis (gum disease) can be seen. The researchers were under the assumption that the association between dental health and hippocampal atrophy might be due to inflammation. Gum disease is a chronic inflammatory condition, and inflammation has been shown to damage the hippocampus. The study included 172 people with an average … Read more

Rheumatoid arthritis linked to dental disorders

by

An interesting article titled “Increased dental visits in patients with rheumatoid arthritis: a secondary cohort analysis of population based claims data,” appears in BMC Oral Health written by Ching-Ya Juan, Chia-Wen Hsu, and Ming-Chi Lu (published December 15, 2022). The article sought to eplore the use of dental care in patients with rheumatoid arthritis (RA) and explore the incidence of dental disorders in patients with and without RA. Rheumatoid arthritis is an autoimmune disease that characterized by persistent joint infammation. RA can affect not only the joints, but it can also involve other organ systems, such as the lung and lead to systemic comorbidities. In the article the authors selected 1,337 patients newly diagnosed with RA between January 2000 and December 2012 and 13,370 patients without RA. The authors found that patients with RA had a higher prevalence (70.3% vs. … Read more
