Background: Caries can be caused by a lack of individual knowledge about dental health and attitudes to pay attention to dental hygiene. Parents have the most important role in determining the personality, habits and behavior of the child in taking care of the teeth and mouth. Every action taken by the parents will have an influence on the character of the child. Parents who provide a positive parenting pattern to their child, will form good personality, habits and behavior towards the child. But on the contrary, parents who are less attentive and do not care will form negative personalities, habits and behaviors.  Purpose: To find out relationship of parents role to caries incident in adolescents at Sungai Loban Subdistrict. Methods: This study used an observational analytic method in the form of cross-sectional research and a simple random sampling technique. The research population was grade VII students at SMP Negeri 1 Sungai Loban as many as 63 respondents. Results: The Spearman test obtained significant score results of 0.000<0.05 which means there is a correlation between the role of parents to the incidence of caries in children. The correlation value is  – 0.927 and includes a very strong correlation in the negative direction (-), it can be interpreted that the relationship is opposite or if the child's caries is high then the role of parents tends to be low.

Background: Periapical radiographic x-ray exposure can blood cells damage, such as platelets by forming free radicals indirectly or attacks DNA and RNA of cells directly. Antioxidants are needed to counteract the effects of free radicals from periapical radiographic x-ray exposure. One of the natural antioxidant compounds that can be used is kasturi leaf extract which contain flavonoid, phenol, tannin, alkaloid, terpenoid, and saponin. Objective: To measure and analyze the effect of kasturi leaf extract on platelets levels of male mice exposed to periapical x-ray radiography. Methods: This study used a true experimental method with a post test only design with a control group design. The samples were used 24 male mice aged 3-4 months which weighed 20-25 grams. Mice were divided into 4 groups, each group consisted of 6 mice. Mice were given kasturi leaf extract and exposed by x-ray periapical radiograph and platelets levels were measured with hematology analyzer automatically. Results: The results showed that the highest platelets level were found in the group that was only given kasturi leaf extract (P4), while the lowest group was in the group that was given kasturi leaf extract and exposed to periapical radiographs once (P1). Conclusion: The result of the study using ANOVA test showed that there was no significant difference in each experimental group. Keywords :   Kasturi leaf extract,  Periapical radiography, Platelets ABSTRAKLatar Belakang: Paparan sinar-X radiografi periapikal dapat merusak sel darah, salah satunya trombosit dengan cara membentuk radikal bebas secara tidak langsung atau mengenai DNA dan RNA dari sel secara langsung. Antioksidan diperlukan untuk menangkal efek radikal bebas dari paparan sinar-X radiografi periapikal. Senyawa antioksidan alami yang dapat digunakan salah satunya adalah daun kasturi yang mengandung flavonoid, fenol, tannin, alkaloid, terpenoid, dan saponin. Tujuan: Untuk mengukur dan menganalisis pengaruh ekstrak daun kasturi terhadap kadar trombosit mencit jantan yang dipapar sinar-X radiografi periapikal. Metode: Penelitian ini menggunakan metode true experimental dengan rancangan post test only with control group design. Sampel yang digunakan adalah 24 ekor mencit jantan berusia 3-4 bulan yang memiliki berat badan 20-25 gram. Mencit dibagi menjadi 4 kelompok, masing-masing kelompok berjumlah 6 ekor mencit. Mencit diberi ekstrak daun kasturi dan dipapar sinar-X radiografi periapikal dan kadar trombosit diukur menggunakan hematology analyzer secara otomatis. Hasil: Hasil penelitian menunjukkan kadar trombosit tertinggi terdapat pada kelompok yang hanya diberi ekstrak daun kasturi (P4), sedangkan kelompok terendah terdapat pada kelompok yang diberi ekstrak daun kasturi dan dipapar sinar-X radiografi periapikal sebanyak 1 kali paparan (P1). Kesimpulan: Hasil penelitian dengan uji ANOVA menunjukkan tidak terdapat perbedaan yang bermakna tiap antar kelompok percobaan.                                           Kata kunci:  Ekstrak daun kasturi, Radiografi periapikal, Trombosit

Background: Exposure to periapical radiographic X-ray radiation can indirectly affect biological material which will trigger the formation of free radicals. An imbalance in the level of free radicals causes oxidative stress. To reduce it, additional antioxidants obtained from nature are needed. Natural antioxidants can be obtained from the peel of red dragon fruit which the function is to reduce the presence of free radicals. Objective: to analyze the effect of red dragon fruit peel extract administration in mice absolute monocyte counts in periapical radiographic exposure. Method: This study was a true experimental design with a post-test only with control group design. The research sample used 24 mice. Samples were divided into 6 groups: the control group was not given with the treatment, P1 to P4 group were given red dragon fruit peel extract at a dose of 100 mg / kg bb and exposed to radiation with different exposures, P5 group was given red dragon fruit peel extract but not exposed. P1 group was exposed to 1 dose (0.63 mGy), P2 group was exposed to 4 doses (1.66 mGy), P3 group was exposed to 8 doses (4.37 mGy), and P4 group was exposed to 12 doses (8.19 mGy). Results: This study showed that there were changes in the number of monocytes in all groups. The Games Howell test showed that the P1 group had a significant difference compared to the P4 and P5 groups. Conclusion: There is an effect of red dragon fruit peel extract administration in mice absolute monocyte counts in periapical radiographic exposure.
