👉 Pictodentalium is a type of dental plaque that typically occurs on the surface of the teeth and can be caused by bacterial overgrowth, food debris, or other factors. It's characterized by yellowish-white spots or patches that can appear in different areas of the tooth, such as the chewing surfaces, crown, and roots. Pictodentalium can lead to gum disease, gingivitis, and even tooth decay if left untreated.
