Abstract Background: Spine health is a significant aspect of adolescent health, but few studies have focused on adolescent sagittal plane health. This study aimed to investigate the current status of sagittal spine morphology and function in adolescents. Method: This cross-sectional study analysed 1152 effective samples obtained from junior and senior high school students (543 boys and 609 girls) from demonstration, middle-level, and general schools in Beijing. Spinal sagittal morphology and function were measured by Spinal Mouse, a spine measuring instrument. The sacrum angle (SA), thoracic kyphosis angle (TKA), lumbar lordosis angle (LLA), inclination angle (INA), sacral range of motion (SROM), thoracic range of motion (TROM), lumbar range of motion (LROM), and inclination range of motion (IROM) were measured. The Matthiass test was used to measure the change in angle after external load placement on the adolescent spine. Sacral angle change (SAc), thoracic angle change (TKAc), lumbar lordosis angle change (LLAc), and inclination angle change (INAc) were also analysed. Result ： Abnormal TKA rate was 48.2% and 44.7% in the junior and senior high school. Abnormal LLA rate was 44.6% and 55.4%. In the spinal mobility test of the junior high school , SROM, TROM, LROM, and IROM were 60.6°±19.1°, 23.0°±16.6°, 23.0°±16.6°, and 136.1°±16.9°, respectively, for boys and 66.0°±34.4°, 14.0°±17.3°, 66.3°±18.6°, and 127.4°±26.8°, for girls. There were significant differences found between boys and girls (P<0.05 or P<0.01). In the Matthiass test, INAc of the junior high school was 5.7°±5.0° and 2.6°±3.7° for boys and girls, whereas INAc of the senior high school was 2.8°±3.3 and 1.6°±3.0, showing significant differences (P<0.01). The canonical correlation coefficient of SA, SROM, LROM, and IROM was 1.3877, -2.5384, -0.6625, and 1.6336. SROM and LROM were found to be negatively correlated with spinal function, whereas IROM was positively correlated with spinal function. Conclusion: Adolescents have a high incidence of thoracic kyphosis. During flexion and extension, the thoracic and lumbar vertebral activity and overall activity are better in boys. However, girls are better at maintaining the strength quality of stable muscle groups with a normal spine shape. Sacral obliquity and pelvic position greatly influence the spinal morphology of adolescents.

The sacral angle (SA), thoracic kyphosis angle (TKA), lumbar lordosis angle (LLA), inclination angle (INA), sacral range of motion (SROM), thoracic range of motion (TROM), lumbar range of motion (LROM), and inclination range of motion (IROM) were measured. The Matthiass strength test was used to measure changes in angles after external load placement on the adolescent spine.Results: Abnormal TKA rates were 48.2% and 44.7% in the junior and senior high school groups, respectively. Abnormal LLA rates were 44.6% and 55.4%, respectively. Spinal mobility test results of the junior high school group were 60.6°±19.1° (SROM), 23.0°±16.6° (TROM), 81.3°±15.4° (LROM), and 136.1°±16.9° (IROM) for boys and 66.0°±34.4° (SROM), 14.0°±17.3° (TROM), 66.3°±18.6° (LROM), and 127.4°±26.8° (IROM) for girls. For the high school group, these results were 66.0°±17.6° (SROM), 21.6°±16.0° (TROM), 77.9°±15.1° (LROM), and 138.4°±16.0° (IROM) for boys and 72.2°±26.9° (SROM), 15.7°±17.2° (TROM), 65.8°±18.2° (LROM), and 133.4°±21.7° (IROM) for girls. There were significant differences between boys and girls (P<0.05 or P<0.01). The Matthiass strength test results indicated that the inclination angle change (INAc) values of the junior high school group were 5.7°±5.0° and 2.6°±3.7° for boys and girls, respectively; however, the INAc values of the senior high school group were 2.8°±3.3 and 1.6°±3.0 for boys and girls, respectively, indicating significant differences (P<0.01).

SROM and LROM were negatively correlated and IROM was positively correlated with spinal function.Conclusion: Thoracic kyphosis and lumber lordosis rates were high. During flexion and extension, Boys had better thoracic and lumbar vertebral activity and overall activity. Girls had better ability to maintain the normal spinal shape with an extra load. Sacral obliquity and pelvic position greatly influence the spinal morphology.

Abstract: Adolescence is a transition period from childhood to adulthood characterized by the presence of physiological amendments, as well as hormonal. Such reformations may influence the hygiene of dental, mouth and gingiva. Thus are results of mental pattern, adolescents cooperation to look after dental and mouth hygiene in order to prevent gingiva’s inflammation when the level of dental and mouth hygiene decreases. Gingivitis is one of periodontal diseases that is particularly vulnerable to occur during adolescence period, when dental and mouth hygiene are not carefully preserved. The purpose of this research is to identify the status of dental, mouth, and gingiva hygiene among advent junior high school adolescents in Watulaney, Regency of Minahasa. This is a descriptive study, with cross sectional study approach. Conducted in Advent Junior High School, Watulaney, Regency of Minahasa. With 63 subjects under Total Sampling method, measured by oral hygine index simplified by Green and Vermillion, and gingiva index by Loe and Sillness. The implication of this study shows that dental and mouth hygiene among adolescents overall reaches the good category obtains 14,28%, medium category obtains 65,08%, and poor category obtains 20,64%. The status of gingiva upon general adolescents 47,62% for light inflammation, 34,92% for medium inflammation, 17,46% for severe inflammation.Keywords: adolecents, oral hygiene status, gingival statusAbstrak: Remaja merupakan masa transisi dari anak menuju kedewasaan yang ditandai oleh adanya perubahan fisiologis dan hormonal. Perubahan ini dapat memengaruhi kebersihan gigi dan mulut serta gingiva. Hal ini disebabkan oleh pola pemikiran, kepatuhan anak remaja terhadap kebersihan gigi dan mulut guna menjaga terjadinya peradangan pada gingiva apabila kurangnya tingkat kebersihan gigi dan mulut. Gingivitis merupakan salah satu penyakit periodontal yang sangat rentan terjadi di usia remaja apabila kebersihan gigi dan mulut tidak terjaga dengan baik. Tujuan dari penelitian ini untuk mengetahui status kebersihan gigi dan mulut serta status gingiva pada anak remaja di SMP Advent Watulaney kabupaten Minahasa. Penelitian ini merupakan penelitian deskriptif dengan pendekatan cross sectional study. Penelitian dilakukan di SMP Advent Watulaney kabupaten Minahasa dengan subjek penelitian sebanyak 63 orang, menggunakan metode Total Sampling yang diukur dengan indeks oral hygiene index simplified menurut Green and Vermillion dan indeks gingiva menurut Loe and Sillness. Hasil Penelitian menunjukkan bahwa status kebersihan gigi dan mulut anak remaja berada pada kategori baik 14,28%, kategori sedang 65,08%, dan kategori buruk 20,64. Status gingiva anak remaja yang memiliki inflamasi ringan sebesar 47,62%, inflamasi sedang sebesar 34,92%, inflamasi berat sebesar 17,46%.Kata kunci: anak remaja, status kebersihan gigi dan mulut, status gingiva
