<![CDATA[Abstract: Aging process brings about several problems, particularly in the realm of oral health inter alia tooth loss in elderly. Dental prosthetic treatments, such as complete denture treatment can be employed to restore aesthetic, masticatory, and phonetic functions. The timing of follow-up appointments significantly influences the success of complete denture treatments. This study aimed to determine the effectiveness of using educational videos of cleaning complete dentures on time of behavior change among the elderly residents at Panti Jompo Pusaka 41 Yayasan Al-Madiniyah. This was an experimental study with a cross-sectional design using a questionnaire consisting of 15 questions. The results obtained 22 elderlies as subjects. Data collection was performed four times: before the video intervention; control I (one day after the video intervention); control II (one week after control I); and control III (two weeks after control II). Changes in elderly behavior were tested using the Friedman test. The results showed that the most significant change of behavior was during control I, which was one day after receiving instructions in the form of a video. The Friedman test resulted in a p-value of 0.001. In conclusion, the best follow-up time that resulted in the most significant improvement in behavior is control I, which is one day after the administration of instructional videos. Keywords: elderly; complete denture; control time; educational videos; behaviour Abstrak: Bertambahnya usia akan menimbulkan beberapa permasalahan, khususnya di bidang kesehatan gigi dan mulut; salah satunya ialah kehilangan gigi pada kelompok lanjut usia (lansia). Pada kehilangan gigi dapat dilakukan perawatan gigi tiruan lengkap (GTL) untuk mengembalikan fungsi estetik, mastikasi, dan fonetik. Waktu kontrol memiliki pengaruh besar dalam keberhasilan perawatan GTL. Penelitian ini bertujuan untuk mengetahui efektivitas penggunaan video edukasi pembersihan GTL terhadap waktu perubahan perilaku lansia pengguna GTL di Panti Jompo Pusaka 41 Yayasan Al-Madiniyah. Jenis penelitian ialah eksperimental dengan desain potong lintang dan menggunakan kuesioner berisi 15 pertanyaan. Pengambilan data dilakukan sebanyak empat kali, yaitu sebelum diberikan video; kontrol I, sehari setelah pemberian video; kontrol II, satu minggu setelah kontrol I; dan kontrol III, dua minggu setelah kontrol II. Perubahan perilaku lansia diuji menggunakan uji Friedman. Hasil penelitian ini mendapatkan 22 lansia sebagai subjek penelitian. Perilaku lansia mengalami perubahan paling bermakna pada saat kontrol I dengan hasil uji p=0,001. Simpulan penelitian ini ialah waktu kontrol terbaik yang memberikan peningkatan perilaku paling bermakna ialah kontrol I, yaitu sehari setelah pemberian instruksi berupa video. Kata kunci: lanjut usia; gigi tiruan lengkap; waktu kontrol; video edukasi]]>
