The jawbone quality indicator which is often used is trabeculation density. To obtain accurate interpretation, analysis of jawbone quality needs modern radiographic imaging modalities that still very limited in Indonesia. In prosthetic dentistry analysis of trabecular bone density in postmenopause women is very important to anticipate the possibility of osteoporotic cases. Because of inadequacy of human eye sight, information obtained from plain conventional radiographic is very limited. With digitized conventional radiogram, dentist could obtain more accurate information to analyze radiographic trabeculation density in Indonesia. The aim of this study is to get more quantitive radiographic data from digitized conventional radiogram comparing those obtained from conventional radiogram. 112 conventional radiograms were evaluated using grading of trabeculation density. The same radiograms then digitized to obta...

The risk of osteoporosis increases with age and can be detected by taking panoramic radiographs to measure the width of the mandibular cortical bone. This study aims to obtain the average width of the mandibular cortical bone in individuals at risk of osteoporosis. Regions of interest were chosen in the mental foramen regions. The average width of the mandibular cortical bone in individuals at risk of osteoporosis aged 40-80years was 4.80618 mm. The mandibular cortical bone in women aged 40–59 years tends to be wider than in those aged 60–80 years. The average width of the mandibular cortical bone in the 40–80year age group in Indonesia could be classified as normal. Clinical article (J Int Dent Med Res 2017; 10(Special Issue): pp. 652-656)

This study investigated the relationship between vertical mandibular bone atrophy and the number of remaining teeth in elderly Indonesian individuals. Material and methods: A total of 148 panoramic radiographs of patients aged ≥ 50 years were selected from dental records at the Radiology Department, Dental Hospital Faculty of Dentistry, Universitas Indonesia, in 2017. To measure vertical mandibular bone atrophy, a vertical line was created running from the crest of the alveolar ridge to the most inferior point of the mandibular inferior cortex through the center of the mental foramen. Subjects were first divided into four groups based on the number of remaining teeth: group I had 1-8 remaining teeth, group II had 9-16, group III had 17-24, and group IV had 25-32. Results: The number of remaining teeth was significantly associated with vertical mandibular bone atrophy. Mean differences and standard deviations for vertical mandibular bone atrophy were significantly higher in groups III and IV patients than in group I and II patients (group I vs. group III: 5.2 ± 1.7, p = 0.016; group I vs. group IV: 5.8 ± 1.6, p = 0.005; group II vs. group III: 3.2 ± 1.1, p = 0.023; and group II vs. group IV: 3.8 ± 1.1, p = 0.003). Patients with fewer remaining teeth were 1.78 times more at risk for a decrease in their mandibular bone volume than those with more remaining teeth. Males were 1.78 times more likely to have a higher mandibular bone volume than females. Conclusion: Mandibular bone atrophy was significant in patients with fewer than half of the total number of teeth remaining.

Mandibular condyle is the most likely region of temporomandibular joint with the most advanced post-pubertal growth rate. The asymmetrical function of the mandibular that has developed differently, is a naturally occurring phenomenon. However, the dysfunction of temporomandibular joint that related to condyle may lead to some symptoms that can become chronic and difficult to manage. This study aims to compare condylar height symmetry and temporomandibular disorder symptom in the subject with complete teeth. This is a descriptive analytic study with cross sectional approach of the subject with complete erupted teeth until the second molar, except the third molar. Early detection of temporomandibular disorder (TMD) symptoms using Temporomandibular Disorder Diagnostic Indexes (TMD-DI). Based on Habets' method, the difference of 6% between right and left condylar height was categorized as asymmetry. This study found that 17.7% (n=12) of patients with symmetry height condylar and 38.2% (n=26) showed asymmetry had TMD symptom. On the other hand, 39.7% (n=27) of patients with symmetry height condylar and 4.4% (n=3) with asymmetry had no TMD symptoms. There was a significant difference (p=0.00). In conclusion; condylar height symmetry should be considered in the occurrence of TMD symptoms in order to understand the development of mandibular asymmetry and multifactorial of TMD.

According to the International Osteoporosis Foundation, one in four women over the age of 50 is at risk of osteoporosis, leading to fracture. In its early stage, osteoporosis has no specific symptoms and is often ignored as a result. Currently, dual-energy x-ray absorptiometry is considered the gold standard for osteoporosis detection, but it is expensive in Indonesia, and its availability is limited. Thus, a new, alternative early detection tool for osteoporosis risk is being developed by measuring the mandibular cortical width (MCW) on panoramic radiographs. To compare between the mean of MCW in women aged 31-45 years and 46-75 years. This study utilizes 270 digital panoramic radiographs of women aged 31-75 years from the Dental Hospital, Universitas Indonesia. MCW was measured using radiography software with 2x magnification of the region of interest. Average and standard deviation in women a...

Mandibular condyle is the most likely region of temporomandibular joint with the most advanced post-pubertal growth rate. The asymmetrical function of the mandibular that has developed differently, is a naturally occurring phenomenon. However, the dysfunction of temporomandibular joint that related to condyle may lead to some symptoms that can become chronic and difficult to manage. This study aims to compare condylar height symmetry and temporomandibular disorder symptom in the subject with complete teeth. This is a descriptive analytic study with cross sectional approach of the subject with complete erupted teeth until the second molar, except the third molar. Early detection of temporomandibular disorder (TMD) symptoms using Temporomandibular Disorder Diagnostic Indexes (TMD-DI). Based on Habets' method, the difference of 6% between right and left condylar height was categorized as asymmetry. This study found that 17.7% (n=12) of patients with symmetry height condylar and 38.2% (n=26) showed asymmetry had TMD symptom. On the other hand, 39.7% (n=27) of patients with symmetry height condylar and 4.4% (n=3) with asymmetry had no TMD symptoms. There was a significant difference (p=0.00). In conclusion; condylar height symmetry should be considered in the occurrence of TMD symptoms in order to understand the development of mandibular asymmetry and multifactorial of TMD.

Methods Periapical radiography examinations with a pararelling technique, both conventional and digital, were performed on 18 male and 34 female patients with edentulous maxillas and mandibles. The trabecular bone pattern of 42 maxillary and 61 mandibular regions of interest (ROIs) was classified into five grades. Grayscale density measurements were made within a marked area of the ROI in the image of the periapical digital radiograph in the same corresponding trabecular region. To obtain conversion values, including the effects of age, gender, and region of the jaw, Journal Article Converting conventional radiographic examination data of trabecular bone pattern values into density measurement values using intraoral digital images

According to the International Osteoporosis Foundation, one in four women over the age of 50 is at risk of osteoporosis, leading to fracture. In its early stage, osteoporosis has no specific symptoms and is often ignored as a result. Currently, dual-energy x-ray absorptiometry is considered the gold standard for osteoporosis detection, but it is expensive in Indonesia, and its availability is limited. Thus, a new, alternative early detection tool for osteoporosis risk is being developed by measuring the mandibular cortical width (MCW) on panoramic radiographs. To compare between the mean of MCW in women aged 31-45 years and 46-75 years. This study utilizes 270 digital panoramic radiographs of women aged 31-75 years from the Dental Hospital, Universitas Indonesia. MCW was measured using radiography software with 2x magnification of the region of interest. Average and standard deviation in women a...
