Molar permanen pertama rentan terhadap karies karena gigi ini merupakan gigi permanen yang pertama kali tumbuh dan banyak tidak mengetahui keberadaan gigi ini. Penelitian ini bertujuan untuk melihat hubungan perilaku kesehatan gigi-mulut ibu dengan angka karies molar permanen pertama pada anak. Disain penelitian adalah analitik deskriptif potong lintang. Variabel yang dihubungkan adalah perilaku kesehatan gigi-mulut ibu dengan angka karies molar permanen pertama. Kuisioner untuk menilai perilaku kesehatan gigi-mulut ibu melalui model Knowledge, Attiude, and Practice (KAP) dan pemeriksaan karies dilakukan secara klinis mengikuti WHO. Perilaku kesehatan gigi-mulut ibu dinilai dari pengetahuan, sikap dan tindakan kesehatan gigi-mulut ibu.

Uji komparasi antara karakteristik ibu dengan angka karies molar permanen pertama pada anak memperlihatkan ada perbedaan tidak bermakna (p ³ 0,05). Uji korelasi antara perilaku kesehatan gigi-mulut ibu dengan angka karies molar permanen pertama menunjukkan korelasi kuat (r ³ 0, 66) dan bermakna (p £ 0,05). Uji korelasi antara perilaku kesehatan gigi-mulut ibu dengan pengetahuan, sikap, dan tindakan kesehatan gigi-mulut anak yang karies dan tidak karies ditemukan korelasi kuat (r ³ 0,66) dan bermakna (p £ 0,05).
