Pop-Cola Acids and Tooth Erosion: An In Vitro, In Vivo, Electron-Microscopic, and Clinical Report
Figure 12
In (a–e), the teeth are smaller, with shiny surfaces. The full intercuspal occlusion shows spaces from reduction of cuspal height; the incisors, canines, and premolars are eroded palatally and worn down with attrition. (f, g) are occlusal views of Upper and Lower arches. Loss of occlusal tables from attrition and erosion is evident on the premolars and molars; there is occlusal saucerisation of cusps on the first and second molars. Figure 12(h) is a pre-op view of upper anteriors. Note short vertical height of incisors and loss of buccal enamel on all upper teeth. Figures (i, j, k) are healing post-op views after clinical crown lengthening. The central incisors are longer, the premolar palatal cusps are lost, and the palatal aspects show a clear palatal step where enamel has eroded away. This erosive pattern involves the buccal surfaces of the upper teeth and is decidedly different when compared to the erosive patterns encountered with GORD [17].
