Kesimpulan: Tingkat kebutuhan perawatan ortodonti berdasarkan Index of Orthodontic Treatment Need menunjukkan bahwa rata-rata 60,5% remaja tidak membutuhkan perawatan ortodonti dan rata-rata 20,6% remaja sangat membutuhkan perawatan ortodonti. Melalui studi ini masyarakat diharapkan dapat menjaga kesehatan gigi dan mulutnya khususnya terkait maloklusi untuk mencegah peningkatan kebutuhan perawatan ortodonti. Kata kunci: anak sekolah, indeks, kebutuhan perawatan ortodonti, remaja

Background: Malocclusion creates problems in mastication, swallowing, speech, high risk of trauma, periodontal disease, caries and decreased aesthetic which can affect psychosocial. People with malocclusion often receive poor response from others, such as insult or inappropriate nickname. The psychological effects on people with malocclusion include inferiority, embarrassment, difficulty in adaptation, emotional disorder, lack of confidence, uncomfortable social interaction, unhappy, and often compare themselves with others. These will affect a person’s development, especially during adolescence. Objective: The purpose of this research was to know about correlation between the orthodontic treatment needs with the psychosocial condition in adolescent at SMPN 1 Marabahan. Methods: This research was an observational analytic using cross sectional approach. The sample size using Slovin in this research was 76 students of SMPN 1 Marabahan. Data collection was performed using IOTN-DHC and PIDAQ questionnaire. Data analysis consisted of univariate analysis which described each variable and bivariate analysis with Spearman test. Results: The orthodontic treatment needs at SMPN 1 Marabahan based on the highest IOTN-DHC was in the category of really need the treatment. They were about 40 people (53%). The psychological condition in adolescent based on the highest PIDAQ was on the student with an average score of 45.22. Conclusion: There is a significant correlation between orthodontic treatment needs with the psychosocial condition of adolescent.

Background: Psychosocial is defined as a condition that occurs in individuals that can be seen from their behavior and influenced by the emotional development, personality, and individual social relationship. One of the factors that can affect psychosocial is the state of the teeth. The condition of misalignment teeth can have a psychosocial impact, especially adolescents. A person who has misalignment teeth should have orthodontic treatment. Orthodontic treatment can improve his psychosocial health condition. Purpose: The purpose of this study was to analyze differences in the psychosocial status of adolescents who did and did not undergo orthodontic treatment. Method: This study used an observational analytic method with a cross sectional approach. The sample size was calculated using the Slovin formula. The study was conducted at SMAN 2 Banjarmasin with a total sample of 93 students consisting of 27 students who did orthodontic treatment and 66 students who did not undergo orthodontic treatment. Data collection using a preliminary survey and PIDAQ questionnaire. Data analysis consisted of univariate analysis to describe the characteristics of each variable and bivariate analysis to see the difference between in the mean of the two groups of subjects using the Independent T Test. Results: The psychosocial status of adolescents who did orthodontic treatment is moderate with an average PIDAQ score is 50.6. The psychosocial status of adolescents who did not undergo orthodontic treatment is moderate with an average PIDAQ score is 45.8. Conclusion: There is no difference in psychosocial status between adolescents who did and did not undergo orthodontic treatment.

Background: Adhesion of Lactobacillus acidophilus can cause secondary caries and failure of tooth restorations. One of the secondary caries prevention methods is the use of bioactive composite resins which have antibacterial properties. The antibacterial effect is further enhanced by the use of bonding which has antibacterial monomers. The two-step adhesive system in the 6th generation bonding has acid monomers which have been shown to significantly inhibit bacterial growth. Objective: To determine and analyze the effect of bonding application with antibacterial content on the amount of attachment of Lactobacillus acidophilus to bioactive composite resin restoration. Methods: This study design used true experimental with a post-test only design with control group design using 39 premolars 1 tooth divided into 3 groups: the treatment group that was given bonding and the control group that did not use bonding. Results: The results of the One Way ANOVA showed a significant difference (p = 0.000). Post hoc Bonferroni test results showed a significant difference (p = 0.000) between the treatment group and the control group. Conclusion: In the use of antibacterial, non-antibacterial bonding, and without bonding, there were significant differences in the number of attachments of Lactobacillus acidophilus to the restoration material.Keywords: Antibacterial, Bioactive Composite Resin, Lactobacillus acidophilus.ABSTRAKLatar Belakang: Perlekatan Lactobacillus acidophilus dapat menyebabkan terjadinya karies sekunder dan kegagalan restorasi gigi.
