Bisphenol A Exposure in Early Age May Damage Enamel

Bisphenol A (BPA) is a chemical compound that is used to make up resins and plastics. For example, bisphenol A is used in bottles, inside drink cans, and inside food tins. Research has shown that bisphenol A has been found in human blood and urine hence indicting that it has been ingested. Other research has shown that bisphenol A has adverse effects on the development and reproduction of lab animals. Bisphenol A has already been banned from being used in the manufacturing process of baby bottles in Europe. A recent study set out to determine if teeth of rats when treated with low daily doses of bisphenol A are damaged. The researchers showed that the teeth of rats treated with low daily doses of bisphenol A are in fact damaged and that the characteristics present are similar to what has … Read more

Cheese may aid in cavity prevention

In an article appearing in the May/June 2013 issue of General Dentistry, it was found that eating cheese and other diary products may be beneficial in protecting teeth against cavities. The study sampled 68 subjects between the ages of 12 and 15 and looked at their dental plaque pH in their mouth before and after eating cheese, yogurt, and milk. In fact, three different groups were used one that eat cheddar cheese another that drink milk and another that eat sugar free yogurt. Each group was told to eat/drink for around 3 minutes and then swish their mouth with water. Then the researchers measured the pH level of each subject’s mouth at 10, 20 and 30 minutes after they finished eating/drinking. The researchers found that the groups who drank milk and ate yogurt had no changes in pH levels in … Read more

Wisdom Teeth Caries Experience and Periodontal Pathology in Young Patients

An interesting article explored the prevalence of caries experience and periodontal pathology on asymptomatic wisdom teeth in young adults appears in a 2012 issue of the Journal of Oral and Maxillofacial Surgery by Rachel N. Garaas and et al. titled “Prevalence of third molars with caries or periodontal pathology in young adults” (J Oral Maxillofac Surg. vol. 70, pages 507-513, 2012). The article seeks to help inform young adults who are seeking advice about the extraction or retention of wisdom teeth about if these teeth can remain symptom free or not. The study includes 409 patients with an average age of 25. The authors define a periodontal probing depth of at least 4 mm as indicative of periodontal inflammatory disease. The authors found that a periodontal probing depth of at least 4 mm was detected more often on a mandibular … Read more

Association Between Partially Erupted Mandibular Third Molar and Caries in Distal Second Molar

An interesting article titled “Association between the presence of a partially erupted mandibular third molar and the existence of caries in the distal of the second molars,” appears in the International Journal of Oral and Maxilofacial Surgery by S. G. M. Falci and et. al. (October 2012, pp. 1270-1274). The article mentions how previous studies have shown that caries on the mandibular second molar due to the presence of partially erupted third molars has varied between 7% and 32%. The article criticizes prior work where studies based their prevalence data on panoramic radiographs which is not as good as periapical radiographs when diagnosing caries. The authors state “The lack of sample characterization, the absence of sample calculation, the deficient or inadequate statistical analysis and the absence of a description of the eligibility criteria, discredits the scientific evidence of these previous … Read more

Sports and Energy Drinks Can Cause Permanent Tooth Damage

I have previously written about how sports and energy drinks can cause tooth erosion see https://blog.teethremoval.com/energy-drinks-cause-tooth-erosion/. Studies have shown that 30% to 50% of U.S. teens are consuming energy drinks, and up to 62% are consuming at least one sports drink per day. A study published in the May/June 2012 issue of General Dentistry, the journal of the Academy of General Dentistry, found that an alarming increase in the consumption of sports and energy drinks, especially among adolescents, is causing irreversible damage to teeth — specifically, the high acidity levels in the drinks erode tooth enamel, the glossy outer layer of the tooth. Poonam Jain, BDS, MS, MPH, lead author of the study says “Young adults consume these drinks assuming that they will improve their sports performance and energy levels and that they are ‘better’ for them than soda. Most … Read more
