“…Many radiographic studies have shown reductions in this thickness in older females [11]. Recently, Dutra et al, [24] showed that measurement of MI was accurate in panoramic radiographs and that it was representative of the true bone status.…”

“…No suitable machines are available in Laos. A number of studies have indicated that a dental panoramic radiograph may be a suitable tool to measure bone mineral densities [12][13][14][15][16][17][18][19][20]24,25) . In this study digital panoramic radiographic equipment was used to obtain the images.…”

“…Images were exported as DICOM image stacks to the Department of Oral and Maxillofacial Radiology, Nihon University School of Dentistry, by a telemedicine system with functions for image viewing, image transfer, DICOM storage real-time video conferencing, and 24 MCW has been shown to be a good measure of bone mass in the mandible compared with the other indices [12][13][14][15][16][17][18][19][20][21][22][23][24][25] . Sisounthone et al 21) have reported that the overall average MCW of 519 Laotian patients aged 7-79 years was lower than that observed in Europeans.…”

The purpose of this study was to determine correlations between height and weight with mandibular cortical width (MCW) that may aid identifi cation of bone mineral density (BMD) in a pediatric population. A total of 122 patients (69 boys and 53 girls) aged 4 to 6 years old who were patients at the Dental Hospital of Faculty of Dentistry (UHS, Lao P.D.R.) participated in the study. Anthropometric data of height and weight were recorded. Digital panoramic radiographs were taken and transferred to Nihon University, Tokyo via telemedicine system. MCW was measured using a SDS-DICOM viewer application. The Mann-Whitney U test was performed to analyze MCW gender diff erences. Tukey -Kramer method was performed to determine means of MCW, Height, Weight between each age group. The Pearson's correlation test was performed to analyze the correlation between MCW and Height or Weight. P values less than 0.05 were considered statistically significant. The range of MCW were between 1.40-3.03 mm in males and 1.68-2.80 mm in females, with no sexual diff erences. As age increased, each parameter (MCW, Height, Weight) increased, but no signifi cant diff erence between age groups was detected in MCW. There were positive signifi cant correlations between height and MCW, but not between weight and MCW. This pilot study has shown that MCW does not appear to be a useful indicator for the diagnosis of hidden children osteogenesis. Further studies are needed to examine if other panoramic radiomorphometric indices could be more relevant.

“…Mental Index (MI) is the measurement of MCW at the mental foramen region as described by Ledgerton et al, [28]. Dutra et al, [29] showed that the measurement of MI is accurate in panoramic radiographs and representative of true bone status. The present study compares the MCW of postmenopausal women with osteoporosis and a normal group using panoramic radiography.…”
