ABSTRAKLatar Belakang: Proses penuaan dapat menyebabkan perubahan fisiologis pada jaringan gigi dan mulut, termasuk fungsi pada sendi temporomandibula. Mastikasi merupakan salah satu fungsi sistem stomagtonati yang dapat dipengaruhi oleh gangguan sendi temporomandibula (Temporomandibula Disorders). Tujuan: Menganalisis hubungan antara gangguan sendi temporomandibula terhadap kemampuan mastikasi, serta menganalisis pengaruh faktor sosiodemografi terhadap gangguan sendi temporomandibula dan kemampuan mastikasi. Metode: Penelitian ini dilakukan dengan desain cross sectional pada 100 pasien Puskesmas Kecamatan Kramat Jati berusia 60 tahun ke atas. Dilakukan pencatatan diri responden, pemeriksaan klinis intraoral, dan wawancara menggunakan kuesioner kemampuan mastikasi dan ID-TMD. Hasil penelitian: Gangguan sendi temporomandibula memiliki hubungan (p < 0,05) terhadap kemampuan mastikasi. Terdapat hubungan antara usia dengan gangguan sendi temporomandibula, tetapi tidak terdapat hubungan antara jenis kelamin, tingkat pendidikan dan status ekonomi dengan gangguan sendi temporomandibula. Terdapat hubungan antara usia, tingkat pendidikan, dan status ekonomi dengan kemampuan mastikasi, tetapi tidak ada hubungan antara jenis kelamin dengan kemampuan mastikasi. Kesimpulan: Terdapat pengaruh gangguan sendi temporomandibula terhadap kemampuan mastikasi pada lansia.

ABSTRACT
Background: Aging process involve physiological changes in the teeth and mouth tissues, including temporomandibular joint function. Mastication is one of the main functions of the stomatognathic system that may be affected by temporomandibular disorders. Objectives: To analyze the relationship between temporomandibular disorder towards masticatory ability, to analyze sociodemographic factors (age, gender, educational level, and economic status) towards temporomandibular disorder and masticatory ability. Methods: Cross-sectional study was conducted on 100 patients of Puskesmas Kramat Jati aged 60 years and over. Subject's data and oral examination were obtained, and interview for masticatory ability and ID-TMD were conducted. Results: There was correlation (p < 0.05) between temporomandibular disorder towards masticatory ability. There was correlation between age towards temporomandibular disorder, but there was no correlation between gender, educational level and economic status towards temporomandibular disorder. There was correlation between age, educational level, and economic status towards masticatory ability, but there was no correlation between gender towards masticatory ability. Conclusion: This study shows that temporomandibular disorders negatively influence masticatory ability in elderly.
