The Correlation of Mandibular Incisor Crowding and Third Molars in Brazilians

by

An article written by Lilian-Harumi Karasawa and 4 others titled ” Cross-sectional study of correlation between mandibular incisor crowding and third molars in young Brazilians,” appears in Med Oral Patol Oral Cir Bucal (currently in press the version I have looked at but was accepted in November 2012). The article sets out to examine the correlation between lower incisor crowding and the mandible third molar (lower wisdom tooth).  The ability of a lower wisdom tooth to have lower incisor crowding has been debated and looked at by many researchers over the years. See for example Review of the Wisdom Behind Third Molar Extractions. The possibility that a lower wisdom tooth can cause crowding is often given as a justification for removing a lower wisdom tooth to prevent abnormal orthodontic conditions. In this study the researchers took 300 healthy Brazilian young … Read more

Avoiding Nerve Injuries with Lower Wisdom Teeth

by

A study (in press) appears in the International Journal of Oral and Maxillofacial Surgery (2012) titled “Early extraction: a silver bullet to avoid nerve injury in lower third molar removal?” by Q. B. Zhang and Z. Q. Zhang. At the beginning of the article the authors discuss how lower third molars show the highest incidence of impaction and are responsible for pathology such as pericoronitis, periodontitis, pain, cysts, tumors, and second molar-tooth crown resorption. I have discussed the risks of keeping wisdom teeth in over here http://www.teethremoval.com/risks_of_keeping_wisdom_teeth.html The authors also discuss the complications associated with removal of third molars which I have elaborated on in great detail here http://www.teethremoval.com/complications.html. In this study two groups of patients from China were grouped: A) those less than 23 and with immature teeth, and B) those greater than 23 and with mature teeth. Group … Read more
