Background: In recent years, age estimation in forensic medicine has become so important. Teeth are used to estimate age as valuable indicators. Objectives: This study aimed to compare Cameriere and Demirjian methods in estimating chronological age (Age) in an Iranian population and to develop a modified Cameriere method. Methods: In this cross-sectional study, we investigated a total of 486 panoramic radiographs of individuals aged 5 - 15 years adopted from two craniofacial radiology centers in Babol, northern Iran, in 2019. The dental age of subjects was assessed by Demirjian (DAge) and Cameriere (CAge) methods and compared with their chronological age. Also, a formula was designed based on the Cameriere method for our studied population, and the results of the original and modified Cameriere (MCAge) methods were compared. Results: The mean ± SD of Age (10.38 ± 2.30) had a significant difference with DAge (10.67 ± 2.33) and CAge (9.77 ± 2.01) (P < 0.001). The modified Cameriere formula was more accurate than Cameriere one, and MCAge was 10.38 ± 2.12, indicating no significant difference with Age (P = 0.993). Conclusions: According to our results, both Demirjian and Cameriere methods were not reliable for age estimation in the Iranian population. However, the modified Cameriere formula had a very high accuracy in estimating the age of the studied population.

Background: Growing individuals not only differ in the timing of the maturational events, but also in the sequence of these events. Age is one of the essential factors, which play an important role in every aspect of life like in clinical, medico-legal, forensic and anthropological applications and in planning treatment of   orthodontic and pedodontic patients. The aim of the study was to determine dental age from                       orthopantomogram using Demirjian’s method and Nolla’s method and to evaluate the interrelationship     between chronological and dental age according to both these methods. Materials and Methods: A cross sectional study was carried out in 177 orthopantomograms of the patient aged between 5 to 15 years. Dental age estimation was done with Demirjian’s and Nolla’s method. Results: The mean chronological age 10.14 + 3.16 compared with the mean Demirjian age 9.58 + 3.39 was statistically non significant p > 0.05 whereas comparision with mean Nolla age 7.88+ 1.56 was significant statistically. Conclusions: Both methods showed delayed dental age compared to chronological age. Demirjian’s method was more  applicable to    assess the dental age in Nepalese children compared to Nolla’s method.Keywords: chronological age; dental age; Demirjian’s method; Nolla’s method.

Estimation of dental age in forensic odontology is crucial in biological dentistry Coronal Pulp Cavity Index (CPCI) as one method to check the correlation between the reduction of the coronal pulp cavity and chronological age. The present study aims to find out whether CPCI method can be used to estimate the dental age on lower second premolar and first molar with periapical radiographic analysis. The cross sectional study was conducted on 60 patients (30 males and 30 females) in the age range of 21 and 30 years. They were subjected to periapical radiographs on lower second premolar and first molar. The Coronal Pulp Cavity Height (CPCH) and Coronal Length (CL) was measured using vision measuring scope DC 3000 and electronic digital caliper. The values obtained were subjected into the formula of TCI = [CPCL × 100]/CL. The mean of TCI score and average chronological age were analyzed using paired T test to find out the correlation between the chronological age and the estimated dental age, P > 0.05 is considered as significant. There was no significant difference between the estimated dental age and chronological age in both lower second premolars (p=0.119) and first molars (p=0.224). CPCI method can be used to estimate the dental age on healthy lower second premolar and first molar.

Objective: To assess dental age and deviations of dental from chronological age according to the Willems and Cameriere methods (European formula) in patients with cleft lip and/or cleft palate (CL/P) and compare it with control group. Design: Retrospective cross-sectional study. Setting: Clinic of Orthodontics. Participants: Sixty-nine patients with CL/P between 6 and 15 years of age (55 with unilateral and 14 with bilateral CL/P) with 148 panoramic radiographs. The same number of radiographs was examined in the age-matched control group. Main Outcome Measures: Estimation and comparison of dental age and differences of dental from chronological age in relation to the type of cleft, sex, and age in the group of patients with and without CL/P according to Willems and Cameriere method. Results: No significant intersex and intergroup differences were found in deviations of dental from chronological age according to Cameriere method ( P > .05). Significant difference in deviation of dental from chronological age was found between the patients with and without CL/P according to Willems method ( P < .001). Conclusion: Cameriere European formula for dental age estimation, which is not influenced by sex and tooth morphology, showed similar dental development of children with and without CL/P. However, Willems method detected that deviation of dental from chronological age significantly differed between children with and without clefts.

Anthropologic parameters of the spleen are important because many diseases present with reduction or enlargement of the spleen. No data exists about the standard dimensions of the normal spleen in Iranian population. Therefore, the objective of the study was to investigate anthropologic parameters of the spleen in Iranian cadavers.  In 2014-2015, this cross sectional study was undertaken from the Razavi Khorasan Province of Iran. Iranian cadavers (n=693, 152 female/541 male) with no history of poisoning, drug or alcohol addiction, no gross abnormality and injury of the spleen were included in the study. The length, width and thickness of spleen were measured using a Vernier caliper. The mean values of the demographic data were age= 40.28 ± 20.97 years; weight = 63.68 ± 17.40 kg; height = 160.03 ± 28.45 cm and BMI = 25.03 ± 20.46 kg/m2. The mean values of the spleen length, width, thickness, notch, weight and index in the cadavers were 11.32 ± 3.10 cm, 8.05 ± 2.35 cm, 20.12 ± 9.21 mm, 0.84 ± 1.35, 123.87 ± 82.46 g, and 2.01 ± 1.40, respectively. Accessory spleen was found in five cadavers. The anthropologic parameters of the spleen showed significant difference between males and females except for index of the spleen.  Having standard data on the spleen is useful for radiologists, surgeons, anatomists and anthropologists. The results of the study may provide valuable data in the standardization of the anthropologic parameters of the spleen in the Iranian population.

<p>This study was designed to compare the Intelligence Quotient (IQ) among 3 to 7-year-old strabismic and nonstrabismic children in an Iranian population.</p> <p>In this cross-sectional study, 108 preschool children with equal numbers of strabismic/non-strabismic disorder (age 3-7 years) were randomly selected from exceptional strabismus clinics of Ahvaz and were evaluated with the preschool and primary scale of intelligence versions of Wechsler (WPPSI).</p> <p>In the current study, 108 children were evaluated. In strabismic patients the mean performance, verbal and total IQ were 89.46±19.79 , 89.57±21.57 and 91.54±22.08 respectively.These mean scores in normal children  were 91.89±47.53 , 87.56±15.6 and 89.96±17.62consecuently .The results showed that these three different IQ subscales were not significantly different among 3 to 7 years old strabismic and nonstrabismic children ((P&gt;0.05 for all comparisons). There was no significant difference in IQ between two sexes (P&gt;0.05) while Persian tribe children had greater IQ score compared to other tribes (P&lt;0.05). Also, higher paternal educational status of children related to higher IQ score. IQ score was better in combined deviations and was higher in exotropes than esotropes; however, these differences were not statistically significant.(p&gt;0.05)</p> <p>In this evaluation, we did not found a significant negative interference of strabismus on IQ score of preschool children. It can be concluded that paternal educational level and tribe have a significant effect on intelligent quotient, while this is not the case on sex and ocular deviation.</p> <p><strong>Keywords:</strong> Intelligence quotient, Strabismus, Deviation</p>

Background: Estimation of age has been a major factor in identification of an individual, either living or after death. Objective: To estimate and assess the dental age of children by measuring the open apices of the teeth using panoramic radiograph applying linear regression equation.  Methods: This was a retrospective cross-sectional study conducted on 50 children (25 boys and 25 girls) aged between 5-15 years. The seven left permanent mandibular teeth were assessed using panoramic radiographs which were collected from Medical Record Department, Manipal University, taken during the course of diagnosis and treatment. The number of teeth with closed apical and with open apical end of roots were examined and measured. The values were tabulated and placed on the linear regression equation proposed by Cameriere et al for the estimation of dental age. Result: The result showed no significant difference between the dental age (10.13±1.69 years) and the chronological age (10.31±1.75 years) (p=0.26). The method underestimated the mean age by 0.11 years and 0.23 years for the boys and girls, respectively. The paired sample t- test showed no significant difference between dental age and chronological age for boys (p=0.546) as well as for girls (p=0.351) Conclusion: The estimated age of children by measuring the open apices of the teeth using panoramic radiograph linear regression equation used in the European subjects closely matches with the chronological age in Asian subjects also. Keeping in context to validate more accurately the significance of linear regression equation, there is a need of larger sample size belonging to variety of ethnic and socioeconomic background.DOI: http://dx.doi.org/10.3126/hren.v12i1.11983Health Renaissance 2014;12(1):33-37

Schour-Massler and Demirjian are methods used to estimate chronological age in dental radiographs by looking at the development of permanent teeth and the maturity of the dental age. Chronological age is based on date of birth. Dental age is the age based on the maturity of the teeth. Both of these methods have been widely used in previous studies, but have never been compared. The purpose of this study was to determine whether there are differences in age estimation using the Schour-Massler and Demirjian methods. This study was an observational analytic study with a cross sectional design. The research sample was 46 patients who came to USU General Hospital at the age of 10-16 years. This research was consist at the Radiology Unit of the Faculty of Dentistry, University of North Sumatra. The results of this study indicate the p value of the Wilcoxon test results with the p value for Schour-Massler p=0.090 > 0.05 and Demirjian p=1,000. Both p values> 0.05, there is no significant difference in assessing the estimated age using both methods, so Ha is accepted. In conclusion, the Schour-Massler and Demirjian methods provide estimates of age that are close to actual age, so there is no significant difference between the two methods.

Objectives: To compare Demirjian Dental scoring method with Greulich-Pyle (GP) Skeletal method of age estimation in pubertal children. Materials and Methods: Sample of the study included 267 male healthy subjects of 11-16 years of age group.. Demirjian Scoring system was utilized to evaluate the orthopantomograms to assess their Dental age and the Hand-Wrist radiographs were analyzed to calculate the skeletal age by utilizing GP atlas. Chronological age was obtained from the date of birth of the subject .Both methods were compared with one another and with the chronological age. It was a cross-sectional study and only healthy male subjects without any clinical abnormalities were included in the study. Results: A total of 267 male subjects of 11-16 years of age group were assessed by Demirjian and Greulich Pyle Methods. Both were compared with Chronological Age. Data obtained was statistically analyzed and the Student “t” test was applied in the study population. The mean difference between Chronolgical age and dental age was 0.69years and that of chronological age and skeletal age was 0.87 years. It was observed from dental age assessment that it does not differ much from the skeletal age. Conclusion: It was concluded that Demirjian method of Age Estimation is more precise than Greulich Pyle method of Age Estimation. Furthermore both methods can be used selectively in Medicolegal cases to access bone age which can be easily correlated to chronological age.

Abstract Background This study aimed to measure the serum and synovial interleukin (IL)-37 levels in rheumatoid arthritis (RA) patients compared to patients with primary knee osteoarthritis (PKOA) and healthy controls and to detect its relation to RA disease activity. Results This cross-sectional study included 50 RA patients with a mean age of 40.24 ± 8.62 years, 50 patients with PKOA with a mean age of 56.69 ± 4.21, and 40 healthy controls with a mean age of 41.75 ± 7.38 years. The mean serum IL-37 level in the RA patients (382.6 ± 73.97 pg/ml) was statistically significantly (P < 0.001) the highest among the studied groups; however, it showed a non-significant difference between the PKOA patients (70.38 ± 27.49 pg/ml) and the healthy controls (69.97 ± 25.12 pg/ml) (P > 0.94). Both serum and synovial IL-37 levels were significantly positively correlated with disease activity scores (r = 0.92, P< 0.001 and r = 0.85, P < 0.001), tender joint counts (r = 0.83, P < 0.001 and r = 0.82, P < 0.001 ), swollen joint counts (r = 0.72, P < 0.001 and r = 0.60, P < 0.001), visual analog scale (r = 0.82, P < 0.001 and r = 0.82, P < 0.001), erythrocyte sedimentation rate (r = 0.75, P < 0.001 and r = 0.65, P < 0.001), and C-reactive protein (r = 0.93, P < 0.001 and r = 0.79, P < 0.001), respectively. Conclusion Serum and synovial IL-37 were significantly elevated in the RA patients, and they were closely correlated. Being less invasive, the serum IL-37 could be a marker of disease activity and could reflect the effective disease control by drugs. Having an anti-inflammatory effect could not suggest IL-37 as the key player to control inflammation alone, but its combination with other anti-proinflammatory cytokines could be investigated.

Abstract Introduction: Hyperphosphatemia is associated with unfavorable outcomes, and the percentage of patients presenting with this condition in hemodialysis (HD) in kidney foundation units in the state of Santa Catarina (SC) is historically higher than that of patients in the state of Tocantins (TO). Objective: To assess the frequency of consumption of the main dietary sources of phosphorus and to compare them between the two states. Methodology: A cross-sectional study was carried out involving 123 patients, 66 of SC and 57 of TO: 52% were men, average age was 46.9 ± 15.7 years, and mean HD time 48 (57-71) months. A food frequency questionnaire (FFQ) with 33 items that are dietary sources of phosphorus was applied. A consumption score was calculated for sources of organic, inorganic, and total phosphorus, and the six-month average of phosphatemia was obtained. Results: The mean phosphatemia of SC patients was higher (6.2 ± 1.5 vs 4.7 ± 1.3 mg/dL, p <0001) than TO patients, as well as the prevalence of hyperphosphatemia (62% vs 28%; p <10001). In the total sample, the foods most frequently consumed were milk and beans. Comparing the frequency of consumption between the two states, a significant difference was found in 17 items. In TO, beef and beans were the foods most frequently consumed, and in SC, fourteen other items of the FFQ (pork, sausages, dairy products, etc.) were the most frequently consumed. Phosphatemia correlated with the frequency of consumption of inorganic phosphorus sources. Conclusion: the frequency of consumption of several items was different between the states, and this explains the differences in phosphatemia between the two regions.
