Identifikasi Bakteri pada Permukaan Kerja sebelum Tindakan Ekstraksi Gigi

A hospital is a building where sick people are treated or where healthcare services are provided, but hospitals can also become sources of various diseases, known as nosocomial infections or Healthcare Associated Infections (HAIs). Work surfaces on dental units can become vectors for the transfer of microorganisms during various procedures or treatments performed by dentists, such as tooth extraction. This study aimed to identify bacteria on work surfaces before tooth extraction procedures at RSGM Universitas Sam Ratulangi (Unsrat). This was a descriptive and analytical study with a cross-sectional design. Samples were taken using purposive sampling techniques according to inclusion criteria on three types of work surfaces: headrests, light handles, and control panels of work surfaces on four dental units used for tooth extraction procedures. Based on swab examination results, three types of bacteria were identified on work surfaces before tooth extraction procedures: Streptococcus sp. (66.7%), Staphylococcus sp. (25%), and Klebsiella sp. (8,3%). In conclusion, bacteria predominated by Streptococcus sp. were identified on dental unit work surfaces before tooth extraction procedures. Keywords: healthcare associated infections; bacteria; dental unit Abstrak: Rumah sakit dapat menjadi sumber berbagai penyakit, yang dikenal sebagai penyakit infeksi nosokomial atau healthcare associated infections (HAIs). Permukaan kerja pada dental unit menjadi salah satu perantara perpindahan mikroorganisme saat dilakukan berbagai prosedur perawatan atau tindakan oleh dokter gigi; salah satunya ialah saat melakukan tindakan ekstraksi gigi. Penelitian ini bertujuan untuk mengidentifikasi bakteri pada permukaan kerja sebelum tindakan ekstraksi gigi di RSGM Universitas Sam Ratulangi. Jenis penelitian ialah analisis deskriptif dengan desain potong lintang. Sampel penelitian diambil berdasarkan teknik purposive sampling sesuai dengan kriteria inklusi pada tiga jenis permukaan kerja, yakni sandaran kepala, light handle, dan panel kontrol dari permukaan kerja pada empat dental unit yang digunakan untuk tindakan ekstraksi gigi. Hasil pemeriksaan swab teridentifikasi tiga jenis bakteri pada permukaan kerja sebelum tindakan ekstraksi gigi, yakni Streptococcus sp. (66,7%), Staphylococcus sp. (25%), dan Klebsiella sp. (8,3%). Simpulan penelitian ini yaitu teridentifikasi adanya bakteri terutama Streptococcus sp. pada permukaan kerja dental unit sebelum tindakan ekstraksi gigi.
