Tujuan: Mendeskripsikan inequality dalam perceived need dan utilisasi pelayanan kesehatan gigi dan mulut di Indonesia tahun 1993-2014. Metode: Penelitian ini merupakan penelitian analitik deskriptif dengan desain cohort menggunakan data sekunder dari Indonesian Family Life Survey (IFLS) pada tahun 1993-2014 (n = 122.575). Analisis deskriptif, penghitungan Concentration Index (CI) dilakukan untuk melihat inequality pada pelayanan kesehatan gigi dan mulut dengan berbagai karakteristik sosiodemografi penduduk Indonesia pada tahun 1993-2014. Hasil: Dari total keseluruhan responden IFLS 1-5, terdapat 12,86% individu yang memiliki perceived need dan hanya 23,13% individu yang melakukan utilisasi. Kemudian pada hasil analisis concentration index (CI) dari perceived need bernilai negatif pada IFLS 1 (CI = -0,006), IFLS 4 (CI = -0,014), dan IFLS 5 (CI = -0,004) sehingga mengindikasikan adanya signifikansi pro-poor inequality dalam perceived need dan bernilai positif pada IFLS 2 (CI = 0,02) dan IFLS 3 (CI = 0,015) sehingga mengindikasikan adanya signifikansi pro-rich inequality dalam perceived need. Sedangkan pada hasil analisis concentration index (CI) dari utilisasi bernilai positif pada IFLS 1 (CI = 0,111), IFLS 3 (CI = 0,092), IFLS 4 (CI = 0,94), dan IFLS 5 (CI = 0,249) sehingga mengindikasikan adanya signifikansi pro-rich inequality dalam utilisasi pelayanan kesehatan gigi dan mulut bernilai negative pada IFLS 2 (CI = - 0,008) sehingga mengindikasikan adanya signifikansi pro-poor inequality dalam utilisasi pelayanan kesehatan gigi dan mulut. Kesimpulan: Berdasarkan penelitian ini menunjukkan bahwa masih terdapat inequality dalam perceived need dan utilisasi pelayanan kesehatan gigi dan mulut di Indonesia pada tahun 1993-2014.

Objectives: Describe the inequality in perceived need and utilization of dental and oral health services in Indonesia in 1993-2014.

Method: This research is a descriptive analytic study with a cohort design using secondary data from the Indonesian Family Life Survey (IFLS) in 1993-2014 (n = 122.575). Descriptive analysis, calculating the Concentration Index (CI) was carried out to see the inequality in dental and oral health services with various sociodemographic characteristics of the Indonesian population in 1993-2014.

Result: Of the total IFLS respondents 1-5, there are 12.86% individuals who have perceived need and only 23.13% individuals who do utilization. Then the results of the concentration index (CI) analysis of perceived need are negative at IFLS 1 (CI = -0.006), IFLS 4 (CI = -0.014), and IFLS 5 (CI = -0.004), indicating a significant pro-poor inequality. in perceived need and has a positive value in IFLS 2 (CI = 0.02) and IFLS 3 (CI = 0.015) thus indicating a significant pro-rich inequality in perceived need. While the results of the concentration index (CI) analysis of utilization are positive at IFLS 1 (CI = 0.111), IFLS 3 (CI = 0.092), IFLS 4 (CI = 0.94), and IFLS 5 (CI = 0.249) thus indicating the significance of the pro-rich inequality in the utilization of dental and oral health services is negative in IFLS 2 (CI = -0.008), thus indicating a significant pro-poor inequality in the utilization of dental and oral health services.

Conclusion: Based on this research, it shows that there is still inequality in the perceived need and utilization of dental and oral health services in Indonesia in 1993-2014.
