Tuhia he tohutoro mō tēnei rārangi - I whiwhi pūkenga a Kingsley ki te whakairo, ā, i mōhiotia hoki ia mō tōna pūkenga ki te hanga niho whakapakoko. I riro i a ia nga mētara koura e rua i te rarangi i nga Whakataetae o te Ao i New York City (1853)
me Paris (1855). I whakaputaina e ia he ripoata mo te keehi, he tamaiti me te kopae alveolar V-ahua, i te 1858 i roto i te New York Dental Journal. I te tau 1859, i hangaia e Kingsley he mangai waihanga o te rapa Inia ngawari mo tana turoro tuatahi me te mangai pakaru. I te mutunga ka neke ia ki te whakaako ka noho ko ia te Kaihanga o te New York College of Dentistry, hei tumuaki tuatahi mai i te 1865 ki te 1869. I mohiotia hoki a Kingsley mo tana mahi e pa ana ki te papa papa vulcanite e pa ana ki te piko o mua e ahei ai te tangata ki te kai whakamua me o raatau kauae o raro. I muri mai ka whakarerekehia e Hotz tana taputapu ka mohiotia ko "Vorbissplatte".
