objective: osteoporosis is the most common metabolic disease of the bone decreasing bone mineral density (bmd) particularly in postmenopausal women. on the other hand, panoramic radiography has several applications in dentistry. it appears that by calculating some indices on panoramic radiographs, we may be able to predict the risk of osteoporosis in high-risk individuals. the present study was...

Results: The mean GI was significantly higher in males (1.56 ± 0.31 mm) when compared to females (1.42 ± 0.34 mm). Hence the present sample was subjected to discriminant analysis with gender as a grouping variable, GI and GA as independent variables. Based on Wilk’s lambda values Gonial index (GI) was observed to provide better sex determination when compared to Gonial angle (GA). Hence 2 diffe...

Introdouction: The purpose of the present study was to determine the possible relationship between gonial angle size and three mandibular morphometric parameters, namely, panoramic mandibular index (PMI), mandibular cortical width (MCW), and antegonial notch depth (AD), in digital panoramic radiographs. Materials and methods: PMI, MCW, and AD were calculated in digital panoramic radiographs of...

objectives: this study sought to assess the relation of mandibular cortical index (mci) with age, gender and gonial angle size in an iranian adult population using digital panoramic radiography. methods: we evaluated 370 digital panoramic radiographs of patients and divided them into five 10-year age groups. each radiograph was assigned to low (≤120°) or high (≥125°) angle groups in terms of th...

Linear mouth opening is often used to assess the limitation of mandibular movement. However, this has a number of limitations. It is dependent on variables such as age, gender and ramus length. A new measure of movement has been developed previously, called the temporomandibular opening index (TOI). Forty-two subjects who did not exhibit signs and symptoms of temporomandibular disorder (TMD) we...

PURPOSE The purpose of this study was to evaluate the accuracy of panoramic imaging in measuring the right and left gonial angles by comparing the measured angles with the angles determined using a lateral cephalogram of adult patients with class I malocclusion. MATERIALS AND METHODS The gonial angles of 50 class I malocclusion patients (25 males and 25 females; mean age: 23 years) were measu...

Methods: We evaluated 370 digital panoramic radiographs of patients and divided them into five 10-year age groups. Each radiograph was assigned to low (≤120°) or high (≥125°) angle grou...

BACKGROUND The gonial angle is one of the most important measurements required for orthodontic treatment and orthognathic surgery. It is difficult to determine the accurate measurement of each gonial angle on cephalometric radiographs because of superimposition of the left and right angles. OBJECTIVES The aim of the present study was to determine the right and left gonial angles on panoramic ...

AIM The gonial angle plays an important role in ensuring a harmonious facial profile. Changes in this angle after surgery may be an esthetic concern for both the patient and the surgeon. The aim of the present study was to evaluate gonial angle changes after mandibular setback by the bilateral sagittal split osteotomy (BSSO) and vertical ramus osteotomy (VRO) techniques. METHODS Fifty-eight m...
