Abstract

Pendahuluan: Tingkat perkembangan dan maturasi seorang pasien tidak dapat diketahui secara pasti dari usia kronologis, dikarenakan adanya variasi waktu percepatan pertumbuhan pubertas pada setiap individu, maka perlu ditentukan usia biologisnya. Usia biologis ini dapat ditentukan dari usia tulang berupa kualitas tulang yang dapat dilihat dari ukuran densitas tulang. Radiograf panoramik dapat menilai kualitas kepadatan (densitas) tulang secara makrostruktur dan mikrostruktur. Penelitian ini menggunakan sampel perempuan karena perempuan cenderung kehilangan densitas mineral tulang lebih cepat daripada laki-laki. Tujuan penelitian ini yaitu menganalisis korelasi usia kronologis dengan densitas tulang pada radiograf panoramik pada pasien perempuan. Metode: Jenis penelitian ini adalah cross-sectional, dengan menggunakan analisis korelasi. Populasi penelitian menggunakan data primer dari seluruh radiograf panoramik pasien perempuan usia 5-35 tahun pada bulan Desember 2016-Januari 2017 di Rumah Sakit Gigi dan Mulut (RSGM) Universitas Padjadjaran dengan jumlah sampel 64 orang. Analisis densitas tulang trabekula mandibula dilakukan dengan menggunakan software ImageJ dengan Region of Interest (ROI) 4x4mm pada tepi distal foramen mentale mandibula. Hasil: Rerata ukuran densitas tulang trabekula pada kelompok usia 5-11 tahun 17,54%, kelompok usia 12-16 tahun 21,06%, kelompok usia 18-25 tahun 24,01%, dan kelompok usia 26-35 tahun 25,96% dengan hasil korelasi Pearson r = 0,827, dan nilai p=0,0001. Simpulan: Terdapat korelasi antara usia kronologis dengan nilai densitas tulang trabekula pada radiograf panoramik pasien perempuan, yaitu semakin bertambahnya usia kronologis maka nilai densitas tulang juga akan semakin meningkat sesuai dengan rentang usia penelitian 5-35 tahun.Kata kunci: Usia kronologis, densitas tulang, radiograf panoramik, software imageJ. ABSTRACTIntroduction: The level of development and maturation of a patient can not be known with certainty from chronological age, due to variations in the time of pubertal growth spurt in each individual, it is necessary to determine the biological age. This biological age can be determined from bone age in bone quality, which can be seen from the bone density measurement. Panoramic radiographs can assess the quality of bone density macrostructure and microstructure. This study used a female sample because female tend to lose bone mineral density faster than male. This study was aimed to analyse the correlation between chronological age and bone density on female patients’ panoramic radiographs. Methods: This research was cross-sectional with correlation analysis. The study population used was the primary data from all panoramic radiographs of female patients aged 5-35 years in December 2016-January 2017 at Universitas Padjadjaran Dental Hospital (RSGM Unpad) with a total sample of 64 people. Mandibular trabecular bone density analysis was performed using ImageJ software with a 4x4mm Region of Interest (ROI) on the mandibular mental foramen’s distal edge. Results: The mean size of trabecular bone density in the 5-11 years age group was 17.54%, the 12-16 years age group was 21.06%, the 18-25 year age group was 24.01%, and the 26-35 years age group was 25.96%; with the results of Pearson correlation r=0.827, and the p-value = 0.0001. Conclusion: There is a correlation between chronological age and the value of trabecular bone density on the panoramic radiograph of female patients, that is, the increasing of chronological age will also increase the value of bone density, according to the age range of the study (5-35 years).Keywords: Chronological age, bone density, panoramic radiographs, image-J software.

Distribution of dense bone island in the jaw through panoramic radiography based on gender and age

“…This hormone can help to form and maintain bone mass. 2 In this study, it was also found that DBI was mostly found in the age group of 17 to 25 years old. This is because at this age range, bone growth, bone modification, and bone density are still in good condition.…”

“…This is because the greatest increase in trabeculae occurs in adolescence and will decrease during the maturation or adulthood and the bone remodelling in adulthood decreases. 2 In the research conducted by Wang et al regarding changes in the size of DBI, the results indicate that the size of DBI has a tendency to increase during adolescence and is stable or does not change in adulthood. 11 Other factors that can cause DBI are most commonly found in late adolescence or the age group of 17-25 years because at this age, orthodontic treatment is usually carried out, which prioritizes aesthetic reasons or psychosocial factors.…”

“…One of the lesions that can be found at this time is Dense Bone Island (DBI). 2 A DBI is a radiopaque mass that is localized, well defined, and varies in size and shape. According to Chintala et al, the diameter of DBI is 2 mm to 2 cm.…”

Differences in Panoramic Mandibular Index value between male and female hypertension patients using panoramic radiography

“…The peak bone growth and development in males are known to be higher than in females, characterized by a larger peak growth in males compared to females, which leads to a slower decrease in mandibular cortical thickness in male patients. 10,19,20 The research results in Table 3 indicate that the group with age ≥ 65 years has the lowest average mandibular cortex value compared to other groups, with a value of 0.22 ± 0.06. These findings are consistent with the study by Naik A et al, which states that mandibular cortical thickness values tend to increase with age.…”

“…17,18 The development and bone density in women are also known to be greatly influenced by estrogen hormone, and during menopause, when the ovaries stop producing estrogen, it leads to an increase in bone loss. 10,19,20 Women usually have a higher level of compliance in taking amlodipine medication compared to men. This is what leads to a decrease in bone density.…”
