Two public health dental hygienists were asked to assess the periodontal needs of persons currently living in six homeless shelters. One study was performed to compare the periodontal status of the adult males to that of the adult females to determine any oral health differences. The total number of people living in all six shelters is 464, and after informed consent was obtained, it was decided to select a sampling of 150 persons for the study. Participant selection was performed by first placing each person who agreed to participate in a male or female category and then placing each person into one of three age groups: 18 to 30, 31 to 45, and 46 to 60. The results of this study were then compared to a similar study performed three years ago prior to state funding that allocated money to dentists who treated the state’s homeless population.
