Systematic Review of Prophylactic Extraction of Third Molars: From Brazil

Many reviews have been conducted in recent years to determine if healthy third molars (known as wisdom teeth) should be prophylacticly extracted as in removed before causing problems. A new study by Moacir Guilherme da Costa and four other researchers titled “Is there justification for prophylactic extraction of third molars? A systematic review,” appears in Braz Oral Res., (São Paulo) 2013 Mar-Apr;27(2):183-8. The article discusses how in the United States roughly 10 million wisdom teeth are extracted from around 5 million individuals each year. The article discuss how several reasons are usually given for extracting wisdom teeth pericoronitis periodontal defects in the distal region of the second molar caries in the third or second molars different types of odontogenic cysts and tumors crowding of the lower incisors indications for orthodontic, prosthetic or restorative purposes The authors state how the majority of dental surgeons feel when there is clinical, radiological or laboratorial evidence of acute or chronic periodontitis, caries, pericoronitis, harmful effects on second molars or disease the removal of third molars is justified. The authors mentioned how several controversies arise surrounding removing healthy asymptomatic wisdom teeth including inadequate study designs small sample size insufficient monitoring time methodological flaws Hence the […]

Dental Anesthesia May Stop the Development of Wisdom Teeth

An interesting study appears in the April 2013, JADA which looks at whether dentists giving inferior alveolar nerve blocks to young children may be stopping wisdom teeth from later developing. The article is titled “Inferior alveolar nerve block and third-molar agenesis: A retrospective clinical study,” and by Jerry Swee and et al., JADA, April 2013, vol. 144, issue 4, pp. 389-395. In the study the researchers looked at children who had received inferior alveolar nerve block (a local anesthesia) between the years of 2 and 6 at the Tufts dental clinic and also had a dental x-ray taken 3 years or after of being initially treated. The researchers arrived at 439 potential wisdom tooth sites from 220 patient records for their analysis. The control group consisted of 376 potential wisdom tooth sites where it was clear that the child never received anesthesia on the lower jaw near where the wisdom tooth could later develop. The other 63 potential wisdom tooth sites made up the study group. The researchers found that in the control group 1.9% of the potential wisdom tooth sites had x-ray evidence of no wisdom tooth buds. On the other hand, in the study group 7.9% of the […]

Fish Oil to Help Periodontal Disease

I have previously discussed in this post http://blog.teethremoval.com/omega-3-fatty-acids-inversely-proportional-to-periodontitis/ that you should be taking omega 3 fatty acids such as fish oil regularly. This is because omega 3 fatty acids have been found to be inversely associated with periodontitis which is inflammation of the tissue surrounding the teeth. Recently researchers in Australia reviewed evidence from eight unique studies that involved humans to evaluate whether fish oil supplementation could be an adjunct therapy for periodontitis. Their review of these studies showed that improvements in clinical measures were common in all studies, but were scientifically significant in two that used a combination of fish oil and aspirin. Although not conclusive, intake of fish oil is recommended for health benefits which extend beyond just your teeth. Dr. Alison Coates from the University of South Australia says: “I would recommend that people ensure they have a sufficient intake of long chain omega-3 fatty acids in their diet for general health. In Australia, these types of fatty acids are considered to be essential with ~500 mg recommended as the suggested dietary target. This equates to approximately 2 fatty fish meals per week.” Dr. Coates and her colleagues say the the evidence for fish oil being effective in […]

Exercise Effective for Preventing Migraines

An interesting study was recently published in Cephalalgia and looked at 91 migraine patients. A third of these patients were asked to exercise for 40 minutes for 3 times a week with the supervision of a physiotherapist, another third were doing relaxation exercises, and the final third of the patients was given topiramate. The study lasted for a total of 3 months, in which the migraine status, aerobic capacity, level of physical activity, and quality of life was evaluated.  Follow ups of the study were carried out after 3 and 6 months. The randomized controlled study was performed by researchers at the Sahlgrenska Academy at the University of Gothenburg in Sweden. The results showed that the number of migraines fell in all three groups that were examined and described above. There was no difference in the preventative effect between the three treatments. Emma Varkey, the physiotherapist and doctoral student responsible for the study stated: “Our conclusion is that exercise can act as an alternative to relaxations and topiramate when it comes to preventing migraines, and is particularly appropriate for patients who are unwilling or unable to take preventative medicines.” I suppose it would be interesting to do further studies at […]

Why Bother With Research

An intriguing article recently appeared in the International Journal of Oral and Maxillofacial Surgery titled “Research – why bother?” (vol. 40, issue 12, page 1346, December 2011) written by G. Dimitroulis. The article discusses of oral and maxillofacial surgery needs research to make itself known as a professional body and not as just a technical trade. A brief mention is made that dual degree programs place time pressures on trainees at the expense of research. The author mentions how head and neck surgical oncology is shared by a number of surgical specialties with mutual interest. The author states “We cannot rely rely on the research experience of other surgical specialties if we are to secure the respect and trust of our medical and surgical colleagues from other disciplines who also have a mutual interest in head and neck oncology.” The author goes on to say “It is only through our diligent efforts to record and analyse our surgical experiences, and making these known to the world through journal publications, that we are able to consolidate our interests in various specialized areas of surgery such as cleft surgery, trauma, surgical oncology and implants and so on.” The author says that all […]
