Systemic sclerosis (scleroderma) is a multisystem disease involving the skin, lungs, heart, kidneys and gastrointestinal tract. It is probably owing to a disorder of the immune system. It may also have some oral manifestations, including limited ability to open the mouth, widening of the periodontal ligament (PDL) space and mandibular bone resorption. We report here on three asymptomatic cases that were referred to our oral and maxillofacial radiology centre for another reason, and in which we suspected scleroderma based on the widening of the PDL in the panoramic view. The early diagnosis was finally confirmed by pathological findings.
Introduction:Determining the skeletal age and remaining growth potential of patients are important factors in orthodontic treatment. Evaluating cervical vertebrae development is a reliable method for determining skeletal age. This study aimed to evaluate the correlation between dental calcification and stages of skeletal maturation.
Materials and methods:This descriptive cross-sectional study was conducted on 84 panoramic radiographs and lateral cephalometrics related to 10-15-year-old patients without systematic diseases affecting dental calcification and development. Patient's skeletal age was determined by the stage of cervical vertebrae development and by using Lamparski's method. Dental age of samples was determined by Demirjian's method. Findings were analyzed by SPSS 18 software using Spearman's correlation test to determine the correlation between the cervical vertebrae development and the dental development stages. P < 0.05 was considered significant.
Results:Spearman's correlation test showed a significant direct correlation between dental age and skeletal age (r2 = 42.5%). The linear relationship between dental age and skeletal age was significant (p < 0.05). The highest correlation coefficient was between the cervical vertebrae development and the stages of mandibular second premolar calcification in girls (rs = 0.609) and in the second molar in boys (rs = 0.471). In Demirjian's method, stage G of the mandibular second premolar teeth in girls and stage F of the mandibular second molar teeth in boys nearly coincided with the pubertal growth spurt.
Conclusion:The findings of this study showed that, in Demirjian's method, stage G of the mandibular second premolar teeth in girls and stage F of the mandibular second molar teeth in boys was most frequent between developmental stages. According to the relatively high correlation coefficient between the dental age and the skeletal age, using dental calcification stages by panoramic radiography may become a simple first-level diagnostic test to determine skeletal maturity, which requires more studies in different ethnicities and places all around the world.
Background: Calcification and morphological variation are fairly common in patients presenting to oral and maxillofacial radiology clinics with stylohyoid complex. Objectives: The present study used digital radiography to investigate in detail whether or not elongated stylohyoid complex is linked to clinical symptoms, gender, and increased age. Finding such relationship can affect the diagnosis of the condition and the selection of treatments. Methods: The present cross-sectional study was conducted on 186 patients aged 30 to 70 presenting to a private oral and maxillofacial radiology clinic in Rafsanjan, Iran, for digital dental panoramic radiography. All the patients completed a demographic questionnaire and clinical symptoms associated with stylohyoid complex. The chi-square test and Fisher's exact test were used to compare categorical variables, while independent two-sample t-test and one-way ANOVA were used to compare quantitative variables, in both men and women and across age groups. The significance level was set at 0.05. Results: A total of 186 participants entered the study, consisting of 90 men (48.4%) and 96 women (51.6%). The mean stylohyoid
