From: Histological characteristics of macrodontic cheek teeth of guinea pigs
Longitudinal section of the clinical crown of a guinea pig cheek tooth. As a result of the loss of connection between the gingiva and structurally changed teeth, food debris penetrates the space between the two adjacent teeth. Bacteria present on the plant fragments penetrate deep into the tooth structure. Dentin, osteodentin and cartilage-like cementum breaks loose on the occlusal surface (H&E, × 100). 1. Plant material, 2. tubular dentin, 3. osteodentin, 4. bacteria
