All authors have read and approved the final manuscript. FN and TM: aided in manuscript writing and editing. There were significant correlations between the TP values measured by the two apertures the bigger the aperture size, the higher the TP value (r0.87-0.91, p<0.01). MS: collected and analyzed the data and created the figures. Mean TP values of 1 mm thick bovine enamel, bovine dentin, human enamel and human dentin were 14.7, 15.2, 18.7, and 16.4, respectively, based on the 3 mm round aperture. TI: designed the project and wrote the manuscript. The morphological variations of dentin make it a difficult substrate to manage in clinical dentistry. Tooth fracture is a major problem in dentistry and a common cause of tooth loss. Since if your teeth are translucent it means that your enamel has been affected, there are several symptoms associated with translucent teeth, even before the condition becomes visible. Symptoms of root fractures are dull pain, gingival swelling, and sinus tracts that lead to deep localized periodontal pockets and vertical bone defects. 1 Thus, transparent dentin is more fragile and susceptible to cracks, 2 which cause root fractures. This condition causes an immune reaction to eating gluten, a protein found in wheat, barley, and rye. Transparent dentin is brittle in comparison with healthy dentin it is also weaker. Celiac disease is another common cause of translucent teeth. The dentin tubule lumens had become filled with mineral (yellow arrows), decreasing the amount of light that scattered off the lumens (Figure 1B). In this case, the transparent dentin was observed using a scanning electron microscope. However, it is difficult for practitioners to determine the presence of this anomaly without extracting the tooth. Dentin transparency is a commonly observed physiological process in aged teeth that starts at the apical end of the root and often extends into the coronal dentin (Figure 1A). The tooth tissue, particularly the optical properties of root dentin, changes as aging progresses. B, Scanning electron microscope image of the transparent dentinĪ 60-year-old patient underwent extraction of the mandibular second premolar because of tooth mobility and severe attachment loss due to periodontal disease. A, Section image of the whole tooth (mandibular second premolar).
