Background: Maxillary and mandibular growth have an important role in determining diagnosis and treatment plans. Knowledge of the growth of the maxilla and mandible becomes very important in designing a proper treatment plan and knowing the mean maxillary and mandibular lengths from the ages of 9–15 means malocclusion can be treated at the appropriate age. Purpose: The aim of this study was to determine the relationship between 9–15-year-old males and females and the length of the maxilla and mandible. Methods: This study used a cross-sectional design. The subjects consisted of 35 male and 45 females aged 9–15 years and 80 cephalometric radiograms were collected using a purposive sampling method from Universitas Sumatera Utara (USU) Oral and Dental Hospital based on inclusion and exclusion criteria. Data were collected by tracing the lateral cephalogram, the maxillary length and mandible lengths being measured on the cephalogram based on the McNamara method through a computer program, CorelDRAW. Pearson’s correlation coefficient was used for statistical analysis. Results: The average maxillary length for 9–15-year-olds was 96.35 ± 7.56 mm. The mean mandibular length for 9–15-year-olds was 122.29 ± 10.43 mm. Based on assessment and result, using the Pearson correlation coefficient test between maxillary length and mandibular length and chronological age, a maxillary length of p=0.003 and mandibular length of p=0.00 were obtained. Conclusion: There was a significant positive relationship between chronological age and maxillary length and mandibular length in 9–15-year-olds of Batak ethnicity.

ABSTRACTIntroduction: Tooth eruption sequence is crucial to be noted, especially during mixed dentition, because this period will give a significant impact on the development of permanent teeth and the development of children's occlusion. One of the effects given is crowded teeth; thus, early detection is required to prevent more severe malocclusion. The purpose of this study was to determine the relationship of the eruption sequences of canines and mandibular premolars with anterior crowding of the patients at the Orthodontic Clinics of the Faculty of Dentistry North Sumatra University. Methods: This research was analytic observational research with cross-sectional design. The sample of this study was 100 panoramic radiographic samples and dental models of patients at the Orthodontic Clinics of the Faculty of Dentistry North Sumatra University in the last ten years. Data collection was carried out through measurements on panoramic radiography and dental models which meet the study criteria. Data were tabulated and analysed by the chi-square test. Result: There was a significant relationship (p < 0.05) between the eruption sequence of canines and mandibular first premolars with anterior crowding. Conclusion: There is found no relationship between age and order of eruption of canines and mandibular premolars. However, there is a significant relationship between sex and order of eruption of canines and mandibular premolars, and also the relationship between the eruption of canines and mandibular premolars with the occurrence of anterior crowding in orthodontic patients.Keywords: Tooth eruption sequence, anterior crowding, mixed dentition.

Pendahuluan: Pemberian ASI dari puting ibu merupakan upaya kesehatan primer untuk menghasilkan sumber daya manusia yang berkualitas. Menyusu ASI dari puting ibu berperan dalam memberikan nutrisi, serta mendukung pertumbuhan dan perkembangan gigi anak. Kenyataannya, banyak ibu yang tidak memberikan ASI langsung dari puting ibu dan menggantinya dengan penggunaan botol. Penelitian ini bertujuan untuk menganalisis perbedaan Leeway space anak-anak yang menyusu melalui puting dan anak-anak yang diberi susu melalui botol. Metode: Jenis penelitian analitik cross-sectional. Sampel penelitian ini adalah 40 orang anak usia 6-8 tahun yang dibagi menjadi 2 kelompok. Penelitian dilakukan melalui pencetakan rahang dan pembuatan model gigi, kemudian dilakukan perhitungan Leeway space dengan metode Moyers. Hasil: Hasil penelitian ditemukan bahwa pada anak yang menyusu ASI langsung dari puting memiliki rerata Leeway space mandibula sebesar 4,230 mm dan maksila 2,770mm. Rerata Leeway space mandibula pada anak yang menyusu dari botol sebesar 3,105mm dan maksila 0,640 mm. Hasil analisis menunjukkan tidak terdapat perbedaan nilai Leeway space yang signifikan antara anak yang menyusu ASI langsung dari puting ibu dan botol. Simpulan: Tidak terdapat perbedaan Leeway space anak-anak yang menyusu melalui puting dan anak-anak yang menyusu melalui botol, baik pada maksila maupun mandibula.Kata kunci: Leeway space, ASI, pemberian susu botol. ABSTRACTIntroduction: Breastfeeding is one of the efforts to develop high-quality human resource to maintain primary health.

Maxillary growth can be assessed from linear measurements, which is the length of the maxilla. The process of growth and development of the maxilla is influenced by several factors, one of which is nutrition. Inadequate nutritional status can interfere with maxillary growth and development. To determine whether there is a relationship between underweight and maxillary growth. Samples were lateral cephalograms and patient data from the Department of Orthodontics, Faculty of Dentistry, The University of North Sumatra who met the inclusion and exclusion criteria. The total sample was 100, consisting of 50 underweight patients and 50 normal-weight patients. The Data was obtained from examination of the Body Mass Index, measurement with the ratio of body weight and height squared then adjusted to the BMI criteria according to the Indonesian Ministry of Health in 2010, then the maxillary length was measured on the cephalogram based on the Anthanasiou method using the CorelDraw application. Data were statistically analyzed using the independent t-test to see if there was a relationship based on maxillary growth (p <0.05). The results of this research stated that mean maxillary length in the normal-weight patient group was 115,824 ± 5.56 mm higher than the underweight patient group of 101.875 ± 4.45 mm. There was a difference in maxillary length between the normal-weight patient group and the underweight patient group (p <0.05). The conclusion from this research that there is a relationship between underweight and maxillary growth.

Background: Beta titanium orthodontic wire is known to have good corrosion resistance but is weak in acidic environments, which advance the corrosion rate. One natural inhibitor that can be used to decrease corrosion is kiwi peel extract, which has a high antioxidant level. Purpose: This study aims to examine the ability of the extract to decrease the corrosion rate and microstructural changes of beta titanium at an acidic pH (pH 5). Methods: The samples used were beta titanium with a diameter of 0.016 x 0.022 in and a length of 6 cm. A total of 28 samples (n=28) were divided into four groups—a control group immersed in pH 5 artificial saliva and three treatment groups immersed in kiwi peel extract at concentrations of 400, 500, and 600 ppm (n=7), respectively. The samples were immersed for seven days at 37oC in an incubator. The corrosion rate was tested using the weight-loss method and microstructure change was analyzed using a scanning electron microscope (SEM). Results: One-way ANOVA showed that there are significant differences in corrosion rates between beta titanium immersed in artificial saliva and beta titanium immersed in kiwi peel extract with p=0.01 (p<0.05). SEM analysis results showed that the group with the least surface changes was the one immersed in 400 ppm of kiwi peel extract. Conclusion: Weight-loss and SEM methods show similar results. Kiwi peel extract proved to decrease the corrosion rate and changes in the microstructure of the wire most effectively at a concentration of 400 ppm.
