, Il est important de connaitre à la fois les moyennes d'âge d'éruption 100 , mais également les marges normales de variations afin de pouvoir déterminer si le développement dentaire est normal

, L'accélération de la croissance physique des enfants depuis les cent dernières années, ne se reflète pas encore dans l'éruption des dents d'après Parner et al. 101 L'éruption est pour eux un phénomène physique et physiologique qui serait bien plus stable que les autres aspects du développement physique des enfants. Wedl et al. sont toutefois plus nuancés et, bien que l'absence d'accélération ait été observée au sein de leur étude, assument que celle-ci s'est sans doute terminée, p.102

, D'autres facteurs comme l'augmentation des diamètres mésio-distaux des dents permanentes de la population d'origine caucasienne sont également à prendre en considération
