The purpose of this study was to evaluate the effects of ovariectomy, the influences of estrogen replacement therapy and / or suplemen CavitD3 on mandible's calsium contents of animal's models. Forty-five female rats were used in this researched. Five rats were sacrificed for unoperated basal controls and the others were bilaterally ovariectomized. The ovariectomized animals were devided into 8 groups and two of these groups were only ovariectomized, the others were treated by estrogen replacement therapy. CavitD3 and combination of both per oral for 2 and 4 weeks and then were sacrificed. Mandible's calsium contents were analyzed by Ion Selective Electrode methode after demineralized with 10% phosphoric acid for 24 hours. Result : there were significant increased of mandible's calcium content at 2 weeks post-ovariectomy, but the results decreased at 4 weeks post-ovariectomy. Estrogen replacement therapy and treated with CavitD3 for 2 and 4 weeks or combination of both for 2 weeks increased the mandible's calsium contents of ovariectomized rats, but therapy combination with estrogen and CavitD3 for 4 weeks had a protective effect to mandible's calsium contents of ovariectomized rats.

Obstruction of the upper respiratory tract (OURT) will cause mouth breathing that is known to influence neuromuscular activity. This will lead to malformation of face growth pattern and head posture that can result in dentocraniofacial deformity. This research aimed to identify the differences in soft tissue profile characteristics in OURT patients compared to normal subjects, and to analyze the differences between boys and girls in this respect. An analytic descriptive study with cross sectional design was applied. The sample consists of 96 subjects including 64 OURT patients (32 boys and 32 girls) and 32 normal subjects (11 boys and 21 girls). The results showed that the OURT patients had convex profile and longer distance than the normal subjects between upper or lower lip to esthetic line (p<0.05). Furthermore, normal male subjects had longer distance of upper lip to E-line than females (p=0.039). The same was also shown in OURT patients, i.e. male patients had longer distance of upper and lower lip to E-line compared to females (p<0.05).

Latar belakang: Prevalensi penyakit osteoporosis di Indonesia tergolong cukup tinggi seiring bertambahnya usia. Berdasarkan hasil Data dan Informasi Kementrian Kesehatan RI (InfoDATIN 2015) mengenai penyakit osteoporosis di Indonesia, tertera bahwa proporsi penderita osteoporosis berusia lebih dari 50 tahun pada wanita mencapai 32,3% dan 28,8% pada pria. Usia lanjut sangat jelas dapat dijadikan sebagai faktor risiko terhadap terjadinya osteoporosis. Didukung pula dengan minimnya pola hidup sehat baik itu olahraga maupun asupan nutrisi tulang dari konsumsi susu masyarakat Indonesia. Hal ini memicu terjadinya porositas bahkan hingga fraktur dini terhadap tulang yang dapat dicegah salah satunya melalui metode deteksi dini Panoramic Mandibular Index (PMI). Tujuan: Memperoleh data rerata rasio ketebalan tulang kortikal pada subjek wanita usia 31-75 tahun secara radiografis pada panoramik berdasarkan metode PMI. Metode: Pengukuran PMI menggunakan sampel radiograf panoramik wanita sebanyak 225. Dibagi menjadi tiga kategori dengan interval 15 tahun, yaitu kategori 1 dengan rentang usia 31-45 tahun, kategori 2 yaitu 46-60 tahun, dan kategori 3 yaitu 61-75 tahun. PMI diukur berdasarkan rasio ketebalan kortikal mandibula terhadap jarak antara margin superior atau inferior foramen mental dan margin inferior dari korteks mandibula. Hasil: Diperoleh rerata dan standar deviasi pada kategori 1 sebesar 0,30±0,032, kategori 2 sebesar 0,28±0,042, dan kategori 3 sebesar 0,24±0,063. Berdasarkan hasil analisis Uji ANOVA, didapatkan perbedaan signifikan antar kategori (p<0,05). Selain itu, berdasarkan hasil pengukuran yang didapatkan, secara statistik pengukuran PMI menunjukkan penurunan seiring dengan pertambahan usia dalam interval usia 15 tahun. Kesimpulan: Nilai PMI menurun seiring dengan pertambahan usia dan secara statistik terdapat perbedaan bermakna diantara kategori usia. ......Background: Prevalence of osteoporosis in Indonesia is quite high with age. Based on the results of Information from Ministry of Health of the Republic of Indonesia (InfoDATIN 2015) regarding the conditions of osteoporosis in Indonesia, it was stated that the proportion of osteoporosis patients aged more than 50 years in women reached 32.3% and 28.8% in men. Old age can clearly be used as a risk factor for osteoporosis. Also supported by the lack of a healthy lifestyle such as physical exercise and bone nutrition intake from milk consumption of Indonesian people. This certainly will trigger the occurrence of porosity even to the early fracture of bone, which one of them can be prevented through the early detection method of the Panoramic Mandibular Index (PMI). Objective: To obtain data on mean cortical bone thickness ratio in female subjects aged 31-75 years radiographically on panoramic based on the PMI method. Method: A total of 225 female panoramic radiograph samples were selected and divided into three categories with 15-year intervals, namely category 1 with an age range of 31-45 years, category 2 is 46-60 years, and category 3 is 61-75 years. PMI is measured based on the ratio of the mandibular cortical thickness to the distance between the superior or inferior margins of the mental foramen and the inferior margins of the mandibular cortex. Results: The mean and standard deviation obtained in category 1 was 0.30±0.032, category 2 was 0.28±0.042, and category 3 was 0.24±0.063. Based on the one-way ANOVA analysis test result, there were significant differences between categories p<0.05. In addition, based on the results of measurements obtained, statistically PMI measurements show a decrease with age in the 15 year age interval. Conclusion: PMI values ​​decrease with age and statistically there are significant differences between age categories.

Tujuan: Mengetahui perbedaan hasil interpretasi superimposisi maksila dan mandibula antara tiga metode superimposisi pada kelompok usia non-growing ≥ 20 tahun. Metode superimposisi maksila yang diteliti adalah pada area best fit, Björk dan Skieller, serta Springate. Sementara metode superimposisi mandibula yang diteliti adalah pada tepi bawah mandibula, Björk dan Skieller, serta Springate. Metode: Tracing dilakukan pada foto sebelum perawatan (T0) dengan membuat garis panduan sella-nasion (SN) dan garis N yang tegak lurus terhadap SN serta struktur anatomis pada regio maksila atau mandibula. Sedangkan pada foto setelah perawatan (T1), tracing dilakukan hanya pada struktur anatomis pada regio maksila dan mandibula saja. Kemudian hasil tracing setelah perawatan (T1) disuperimposisikan di atas hasiltracing sebelum perawatan (T0) berdasarkan berbagai metode superimposisi maksila atau mandibula. Setelah itu garis SN dan N pada tracing sebelum perawatan dipindahkan ke atas hasil tracing setelah perawatan. Terakhir, posisi titik referensi pada maksila (titik ANS, A, dan U1) atau mandibula (titik Pog, B, dan L1) diukur jarak koordinatnya secara vertikal dan horizontal ke garis SN dan N yang berperan sebagai sumbu x dan y. Hasil: Tidak terdapat perbedaan, baik dalam dimensi vertikal maupun horizontal, mengenai hasil interpretasi superimposisi maksila dan mandibula dengan tiga metode superimposisi yang diujikan pada kelompok usia non-growing ≥ 20 tahun. Kesimpulan: Evaluasi perawatan ortodontik pada pasien usia non-growing ≥ 20 tahun menggunakan berbagai metode superimposisi maksila dan mandibula menghasilkan hasil interpretasi yang sama, baik diukur dalam dimensi vertikal maupun horizontal. Sehingga pemilihan metode superimposisi maksila dan mandibula apapun pada pasiennon-growing tidak akan mempengaruhi hasil interpretasi evaluasi perawatan, selama metode superimposisi yang digunakan tetap memperhatikan struktur anatomis yang ada.

Objectives: To compare the interpretation of maxillary and mandibular superimposition between three methods on ≥ 20-year-old non-growing patients. Three maxillary superimposition methods used during the study were best fit, Björk-Skieller, and Springate. Meanwhile for mandibular superimposition, the methods used during the study were inferior border of mandible, Björk-Skieller, and Springate. Method: Tracing was executed on pre-treatment cephalogram (T0) to construct sella-nasion (SN) line and N line which was perpendicular to SN, and also to construct anatomical structures on maxilla or mandible. Tracing at post-treatment cephalogram (T1) was executed on maxillary or mandibular anatomical structures only. Then cephalogram tracing at T1 was superimposed on T0 based on three different superimposition methods on maxilla or mandible. SN line and N line at T0 were then transferred into T1 tracing as a reference line of x and y axis. Hence, the position of maxillary reference points (ANS, A, and U1) or mandibular reference points (Pog, B, and L1) could be accounted vertically and horizontally to the x and y axis. Results: No statistical difference in vertical or horizontal dimention, regarding the interpretation of maxillary and mandibular superimposition between three methods on ≥20-year-old non-growing patients. Conclusion: Post orthodontic treatment evaluation on ≥ 20-year-old non-growing patients using varied maxillary and mandibular superimposition methods may result the same interpretation in vertical or horizontal dimention. Any maxillary or mandibular superimposition methods could be used on non-growing patients and may not affect interpretation on post treatment evaluation, as long as the used methods account any existing anatomical structures.
