While piblokto can often be confused with other conditions (including epilepsy), in which failure to intervene can lead to the victim coming to harm, most cases tend to be benign. Skepticism
Although piblokto has a place in the historical record and official medical canons, a number of Arctic researchers and Arctic residents doubt its existence. The phenomenon, they suggest, may be more rooted in the experience and behavior of the early European explorers than the Inuit themselves.In 1988 Parks Canada historian Lyle Dick began a substantial challenge to the concept that piblokto exists at all. Dick examined the original records of the European Arctic explorers, and ethnographic and linguistic reports on Inughuit societies, and discovered that not only is the majority of academic speculation into piblokto based on reports of only eight cases, but the word "piblokto" / "pibloktoq" does not exist within Inuktun (the Inughuit language); possibly, Dick concluded, this may have been the result of errors in phonetic transcription. In a 1995 paper published in the journal Arctic Anthropology, and in his 2001 book Muskox land: Ellesmere Island in the Age of Contact, Dick suggests that piblokto is a "phantom phenomenon", arising more from the Inuhuit reaction to European explorers in their midst.Similarly, Hughes and Simons have described piblokto as a "catch-all rubric under which explorers lumped various Inuhuit anxiety reactions, expressions of resistance to patriarchy or sexual coercion, and shamanistic practice".
Abfraction is a theoretical concept explaining a loss of tooth structure not caused by tooth decay (non-carious cervical lesions). It is suggested that these lesions are caused by forces placed on the teeth during biting, eating, chewing and grinding; the enamel, especially at the cementoenamel junction (CEJ), undergoes large amounts of stress, causing micro fractures and tooth tissue loss. Abfraction appears to be a modern condition, with examples of non-carious cervical lesions in the archaeological record typically caused by other factors. Definition
Abfraction is a form of non-carious tooth tissue loss that occurs along the gingival margin. In other words, abfraction is a mechanical loss of tooth structure that is not caused by tooth decay, located along the gum line. There is theoretical evidence to support the concept of abfraction, but little experimental evidence exists.The term abfraction was first published in 1991 in a journal article dedicated to distinguishing the lesion. The article was titled "Abfractions: A New Classification of Hard Tissue Lesions of Teeth"  by John O. Grippo. This article introduced the definition of abfraction as a "pathologic loss of hard tissue tooth substance caused by bio mechanical loading forces". This article was the first to establish abfraction as a  new form of lesion, differing from abrasion, attrition, and erosion.Tooth tissue is gradually weakened causing tissue loss through fracture and chipping or successively worn away leaving a non-carious lesion on the tooth surface. These lesions occur in both the dentine and enamel of the tooth.
