The second module, "Filing Dental Records," details factors to be considered in selecting file cabinets and then discusses the amount of space needed for filing cabinets; methods of handling inactive files; alphabetic, numeric, subject, and chronological filing systems; the use of color codes in filing; and filing procedures. The third module, "Dental Accounting," familiarizes the student with various bookkeeping forms, including the daily record, the business summary page, summary of expenditure sheets, monthly balance sheets, annual summary of expense sheets, ledger cards, accounts receivable age analysis forms, and dental insurance claim forms. The fourth module, "Dental Supplies," explains how to maintain an inventory control card and describes the functions of invoices, credit memoranda, rush order forms, back order forms, and laboratory work order forms. Each of the modules takes 60 minutes to complete, provides reinforcement exercises using sample forms, and concludes with a post-test and accompanying answer sheet. (JP)
