A human adult has 32 permanent teeth. Your company requires that each claim list the patient seen (identified by "patient id"), the tooth worked on, and the type of work done. Because of the natural limitation on the amount of cavities that could be filled on any one person, it is rare that a person would have more than a few cavities in the three months of your audit (it is possible for a tooth to have more than one cavity). Using this field, calculate the total number of cavities submitted for each patient. Do any patients seem to be visiting the dentist too often?
