Longitudinal 3D Study of Anterior Tooth Wear from Adolescence to Adulthood in Modern Humans

“…Apart from sex, the fact that tooth wear amounts within a dentition were correlated indicates a general effect of the predisposing or causative factors on the anterior dentition. This is not surprising when considering that the known associated factors, including sex [1,2], diet [2,4,6,9,10], occlusion [11][12][13], and mastication pattern [14], are not expected to have effects solely limited to specific teeth.…”

“…The present study offers unique 3D information on the amount of tooth wear that should be expected in a young population from adolescence to early adulthood. The use of orthodontically treated individuals minimized the potential confounding from occlusal factors that have been shown to be associated with tooth wear development [11][12][13]. On the other hand, it could restrict the generalizability of the findings, though, in modern societies, it is quite common for patients with malocclusion to receive orthodontic treatment.…”

“…Certain occlusal factors, such as overjet and anterior protected articulation, have been associated with the progression of occlusal wear [11]. Subjects with different malocclusions have demonstrated different tooth wear patterns [12,13]. Masticatory function has also been associated with tooth wear [14].…”

Qualitative longitudinal assessment of normal occlusion maturation: 40 years of follow-up

“…[12][13][14] A previous study compared the patterns of tooth wear of patients with Class II malocclusion and normal occlusion. 15 Normal occlusion subjects had greater tooth wear in the anterior region (palatal surface of maxillary incisors and incisal surface of maxillary canines) compared to malocclusion groups. A strong correlation was found between age and tooth wear in Indigenous people of Amazon.…”
