A branch of conservative dental medicine. It is intended to eliminate dental caries consequences. Dental caries is one the most frequent diseases in man. It is caused by acidic dissolution of teeth enamel. Acids form as a result of microbial growth in the oral cavity. They accumulate to form a dental plaque which coupled with poor dental hygiene causes caries development on teeth. This gradually leads to teeth decay making chewing difficult, obstructing communication and affecting esthetics. Dental surgery aims to remove infected and destroyed solid dental tissue, and reconstruct the anatomic entity of affected teeth, as well as their physiological function and esthetics.
