Dental caries is the most common human chronicity. Pellicle, nutritional and dental hygienic habits, micro-organisms in the oral cavity, heritable and environmental factors can all result in dental caries. Initially it can be reversed with a fluoride treatment, but later on it extends deeper, producing a cave that can be treated only with filling. It evolves on surfaces that are hard to clean, such as occlusal fissure and tooth surfaces beside the gum or close to each other, if the patient does not use dental floss.
Treatments may be the following:
sealing and fissures
incisal edge restoration
inlay and onlay (aesthetic fillings)
root canal treatment and filling
