KEMENKES REPUBLIK INDONESIA POLITEKNIK KESEHATAN BANJARMASIN PROGRAM STUDI TERAPI GIGI PROGRAM SARJANA TERAPAN KESEHATAN GIGI 2024 ABSTRAK Skripsi MUKNI HUBUNGAN pH SALIVA DENGAN KARIES GIGI PADA SISWA KELAS I SEKOLAH DASAR NEGERI 3 GUNTUNG MANGGIS KOTA BANJARBARU Pembimbing (I) : Siti Sab’atul Habibah, SKM., M.Kes Pembimbing (II) : Sri Nuryati, SKM., M.Si xv + 42 halaman; 9 tabel; 6 gambar; 15 lampiran Karies gigi merupakan suatu penyakit yang disebabkan karena interaksi bakteri yang memproduksi asam dengan host (gigi), substrat (makanan), dan berkembang seiring berjalannya waktu. Asam akan menyebabkan menurunnya pH yang berulang-ulang dalam waktu tertentu, kemudian mengakibatkan demineralisasi gigi dan proses karies. Riset Kesehatan Dasar 2018 menyatakan Kalimantan Selatan memiliki angka karies 56,17% kelompok umur 5-9 tahun. Data karies gigi anak sekolah dasar di wilayah kerja Puskesmas Guntung Manggis Tahun 2022 sebesar 64,16%. Sekolah Dasar Negeri 3 Guntung Manggis menjadi tertinggi angka prevalensi karies gigi 92% di wilayah kerja Puskesmas Guntung Manggis. Penelitian bertujuan untuk mengetahui hubungan pH saliva dengan karies gigi pada siswa kelas I Sekolah Dasar Negeri 3 Guntung Manggis Kota Banjarbaru. Jenis penelitian ini adalah survei analitik dengan rancangan penelitian Cross Sectional. Sampel diambil dengan teknik Proportional Random Sampling dengan jumlah sampel 92 siswa. Penelitian menggunakan uji statistik yaitu Chi Square. Hasil penelitian ini menunjukkan sebagian besar siswa mempunyai pH saliva asam (73,9%) dan karies gigi yang tinggi (53,3%). Berdasarkan hasil uji Chi Square dengan nilai sig.(2-tailed) ρ = 0,008 < α = 0,05, yang artinya Ho ditolak dan Ha diterima. Kesimpulannya adalah ada hubungan pH saliva dengan karies gigi pada siswa kelas I Sekolah Dasar Negeri 3 Guntung Manggis Kota Banjarbaru. Diharapkan perlu ditingkatkan lagi kegiatan pelayanan asuhan kesehatan gigi dan mulut terutama kegiatan promotif dan preventif yaitu penyuluhan dan pemeriksaan yang berkesinambungan di Sekolah Dasar Negeri 3 Guntung Manggis Kota Banjarbaru untuk mencegah terjadinya karies gigi.

Acid will cause a repeated decrease in pH over a period of time, then result in tooth demineralization and caries. Basic Health Research 2018 states that South Kalimantan has a caries rate of 56.17% in the age group of 5-9 years. Data on dental caries for elementary school children in the work area of the Guntung Manggis Health Center in 2022 was 64.16%. State Elementary School 3 Guntung Manggis has the highest prevalence rate of dental caries of 92% in the working area of the Guntung Manggis Health Center. The study aimed to determine the correlation between saliva pH and dental caries in grade I students of State Elementary School 3 Guntung Manggis Banjarbaru City. This type of research is an analytical survey with a Cross Sectional research design. The sample was taken by the Proportional Random Sampling technique with a sample of 92 students. The research uses a statistical test, namely Chi Square. The results of this study showed that most students had acidic saliva pH (73.9%) and high dental caries (53.3%). Based on the results of the Chi Square test with a value of sig. (2-tailed) ρ = 0.008 < α = 0.05, which means that Ho is rejected and Ha is accepted. The conclusion is that there is a correlation between saliva pH and dental caries in grade I students of State Elementary School 3 Guntung Manggis Banjarbaru City. It is hoped that it is necessary to improve dental and oral health care service activities, especially promotive and preventive activities, namely continuous counseling and examination at State Elementary School 3 Guntung Manggis, Banjarbaru City to prevent dental caries.
