Documentation of oral findings with symbols and the symbolic plan of treatment. Study of reliability and practical worth

: The oral status and a plan of treatment were drawn with aid of special symbols on 141 patients of a policlinic. The treatment was managed of 1. dentists in postgradual education with strict order to follow the plan of treatment, 2. dentists which were given the recommendation to act on plan, 3. dentists without knowledge of treatment plan. A control inspection in every case was done one year afters start of treatment. The group 1 showed the best result followed of group 2. Group 3 had the worst result of treatment. This statement is right for treatment of caries, endodontic and prosthetic treatment but not for periodontal treatment. In this field the differences were small between the 3 groups. Even group 1 had insufficient results of periodontal treatment.
