Latar belakang: Populasi lansia di Indonesia meningkat, sebagian ada yang hidup di PSTW binaan Pemerintah Provinsi DKI Jakarta. Pemerintah memiliki wewenang untuk menjamin ketersediaan fasilitas kesehatan dan pendampingan bagi lansia. Namun hanya sedikit penelitian mengenai lesi mulut pada lansia di Indonesia. Tujuan: Untuk menganalisis kondisi rongga mulut dan penyakit sistemik pada lansia di PSTW DKI Jakarta. Metode: Subjek penelitian didapat melalui metode consecutive sampling pada populasi lansia di 5 PSTW di 3 wilayah DKI Jakarta. Dari 1185 penghuni PSTW diperoleh 273 yang memenuhi kriteria inklusi. Data sosiodemografi dan riwayat penyakit sistemik diambil dari rekam medis di panti. Semua subjek dilakukan pemeriksaan oral, yaitu Oral Hygiene Index-Simplified (OHI-S), Papilary Bleeding Index (PBI), Decay, Missing, Filling-Teeth (DMF-T), Skor Indeks Mukosa Plak (MPS), dan pemeriksaan laju alir dan pH saliva, lesi mulut dan topografi lesi mulut. Subjek diwawancarai tentang kebiasaan yang berhubungan dengan kesehatan mulut. Hasil: Prevalensi lesi mulut terbanyak adalah gingivitis dan prevalensi penyakit sistemik terbanyak adalah hipertensi. Kategori OHI-S buruk, kategori PBI baik, kategori DMF-T sangat tinggi, kategori indeks MPS baik. Terdapat hubungan antara jenis kelamin dan jenis pekerjaan dengan penyakit sistemik pada lansia. Lansia dengan kebiasaan merokok, menyirih, dan minum alkohol cenderung memiliki penyakit sistemik. Lansia dengan penyakit sistemik cenderung memiliki lesi mulut. Kesimpulan: Kondisi mulut dan penyakit sistemik pada lansia yang tinggal di PSTW DKI Jakarta dalam keadaan tidak baik.
