ABSTRAK
Latar Belakang: Lansia mengalami proses penuaan yang melibatkan perubahan pola penyakit, salah satunya penyakit gigi mulut. Masalah utama yang dimiliki lansia adalah kehilangan gigi yang membutuhkan perawatan prostodonsia. Kebutuhan perawatan mendahului perencanaan perawatan prostodonsia. Kebutuhan sendiri dibagi menjadi kebutuhan objektif dan kebutuhan subjektif atau kebutuhan yang dirasakan pasien itu sendiri. Terdapat beberapa hal yang mempengaruhi kebutuhan seseorang, salah satunya adalah tingkat pengetahuan seseorang akan kesehatan gigi dan mulut. Tujuan: Menganalisis hubungan tingkat pengetahuan kesehatan gigi mulut dengan kebutuhan perawatan prostodonsia secara objektif dan subjektif pada lansia, menganalisis pengaruh faktor sosiodemografi (jenis kelamin, tingkat pendidikan, dan status ekonomi) terhadap tingkat pengetahuan kesehatan gigi mulut dan kebutuhan perawatan prostodonsia. Metode: Penelitian ini dilakukan dengan desain cross sectional pada 100 pasien Puskesmas Kecamatan Kramat Jati berusia 60 tahun ke atas. Dilakukan pencatatan diri subjek, wawancara pengisian kuesioner tingkat pengetahuan kesehatan gigi mulut pada lansia, kebutuhan subjektif (need) gigi tiruan, dan pemeriksaan klinis intraoral (kebutuhan objektif). Hasil penelitian: Tingkat pengetahuan kesehatan gigi mulut memiliki perbedaan bermakna (p < 0,05) dengan kebutuhan objektif gigi tiruan pada rahang atas dan kebutuhan subjektif (need) gigi tiruan, tetapi tidak terdapat perbedaan bermakna tingkat pengetahuan kesehatan gigi mulut dengan kebutuhan objektif gigi tiruan pada rahang bawah. Terdapat perbedaan bermakna jenis kelamin dan tingkat pendidikan dengan kebutuhan subjektif (need) gigi tiruan, tetapi tidak ada perbedaan bermakna antara status ekonomi dengan kebutuhan subjektif (need) gigi tiruan. Tidak terdapat perbedaan bermakna antara faktor sosiodemografi dengan tingkat pengetahuan kesehatan gigi mulut dan kebutuhan objektif pada kedua rahang. Kesimpulan: Terdapat pengaruh tingkat pengetahuan kesehatan gigi mulut pada lansia dengan kebutuhan objektif gigi tiruan pada rahang atas dan kebutuhan subjektif (need) gigi tiruan.
