Prevalence of Carious and Non‐carious Cervical Lesions in Archaeological Populations from North America and Europe

Abstract

The prevalence of carious cervical lesions among the five archaeological populations studied ranged from 0 to 65%. Non-carious cervical lesions were not prevalent among these populations, being found predominantly in Mexicans (26%). CLINICAL SIGNIFICANCE Historically, carious and non-carious cervical lesions can be found in individuals with no access to modern oral hygiene tools. The findings of this study are not conclusive, however, as the associations described are not causal. (J Esthet Restor Dent 21:324-335, 2009).

Evidence for the occurrence of gingival recession and non‐carious cervical lesions as a consequence of traumatic toothbrushing

“…, Ritter et al. ). The concept of abfraction has been proposed for the development of NCCLs: lateral forces that create tensile stress in the cervical areas of teeth and which disrupt the enamel microstructure (Lee & Eakle , Braem et al.…”

“…Toothbrushing has been suggested as an aetiological or aggravating factor in their development which seems to be enhanced by the presence of an acidic environment (Sneed 2011). In vitro studies suggest that these defects are not produced by toothbrushing alone (Mannerberg 1960, Dzakovich & Oslak 2008 and they have also been identified in non-toothbrushing populations (Babacar et al 2006, Ritter et al 2009). The concept of abfraction has been proposed for the development of NCCLs: lateral forces that create tensile stress in the cervical areas of teeth and which disrupt the enamel microstructure (Lee & Eakle 1984, Braem et al 1992.…”

The Evolutionary Paradox of Tooth Wear: Simply Destruction or Inevitable Adaptation?

“…The magnitude of load alone cannot be considered the only factor involved in the aetiology of NCCLs. Past modern humans had a stronger masticatory apparatus (as suggested by muscle insertions in the cranium and mandible) than contemporary populations and yet in these early modern humans NCCLs have been rarely observed [4], [5]. However, continuous cyclic occlusal loading can lead to the accumulation of cracks, promoting fatigue and maybe ending in delaminating enamel from dentin [42].…”

Noncarious Cervical Lesions: Why on the Facial? A Theory

“…Often one lingually positioned premolar will demonstrate these defects whereas the more facially oriented canine in the same quadrant is left undisturbed (Figure 1). These lesions have also been reported in early hominids well before the advent of the toothbrush 13 . The question remains why so few lesions occur on the lingual and so many on the facial.…”
