In fingerprint analysis, the determination of hand (right or left) is one of the keys to resolving questions regarding the identity of the donor of the print. It is rare to encounter a complete set of 10-digit fingerprints from the scene of a crime. Although vital and imperative, except for a few studies on whorl patterns, the use of single-digit prints and patterns to ascertain the hand of the donor is scarcely reported in the literature. This research describes a novel approach whereby an analysis of twinned loops was carried out to identify the various parameters that may be helpful in ascertaining the hand of the donor. Bilateral rolled fingerprints from 180 healthy consenting adults belonging to a heterogeneous population of central India were collected. Out of the total of 1800 prints taken, 100 twinned loops (50 on the right hand and 50 on the left hand) were analysed. The following six parameters were considered: the slope of the flow of the apex ridges, the distance between the left delta and the ascending core, the distance between the right delta and the ascending core, mid-core position, the position of the loop and ridge tracing. On applying the chi-square test, the results were found to be statistically significant. Therefore, these parameters were found suitable for the determination of the hand from a single twinned-loop print.

This study was carried out to determine the possible differences between the dermatoglyphic characteristics of the digit and inter-digit areas of Down Syndrome (DS) patients and healthy Nigerians. The dermatoglyphic prints of the digit and inter-digit areas were obtained by using the improvise digital method. Parameters evaluated were the digit patterns, inter-digit patterns and single flexion crease of the fifth digit. Comparison of dermal patterns in DS patients and normal ones was done using Chi-square test at a significant level of P = .05. The result of the digit patterns showed that the total mean percentage frequency for arch, radial loop, ulnar loop and whorl were 5.28%, 0.34%, 75.94% and 18.45% in DS patients and 9.55%, 1.11%, 60.11% and 29.22% in normal subjects respectively. The distribution of dermal ridge differ significantly in digits I, II and III of the right hand and digits II and III of the left hand in patients and normal subjects at P = .05 level. Down syndrome patients had more of open fields in all the inter-digit areas except in inter-digit C. The difference in patterns between DS patients and normal subjects was significant in inter-digit C and D of the left hand only. One normal subject had single flexion crease compared to four in Down syndrome patients. The findings of the study could be used as supplementary diagnostic aid for Down syndrome.

Objective: To analyse the morphological presentation of orofacial clefts, gender, syndromes and systemic anomalies associated with them. Design: This was an epidemiological study performed in the patients who were registered for cleft lip and palate surgeries in our centre. The data was evaluated both retrospectively as well as prospectively. Patients/ Participants: The patients registered from November 2006 to April 2021 were studied. Out of 5276 patients, data of 5004 cases were analysed, rest 272 patients were excluded due to lack of information. Statistical analysis and Chi square test were applied. Results: Cleft deformities were more common in males than females. Cleft lip with palate was the commonest phenotype (52.2%). It was followed by isolated cleft lip (22.9%), isolated cleft palate (22.1%), rare clefts (1.62%) and syndromic clefts (1.18%). Unilateral variants were more frequent than bilateral. In unilateral, left side was more common than the right side. Among bilateral, most of the cases had premaxillary protrusion. In the present study, 3.46% of all the patients had associated anomalies affecting their other organs. Less common cleft phenotypes like microform cleft lip and submucous cleft palate ± bifid uvula showed frequency of 0.62% and 0.64% respectively. Conclusion: Thorough examination of cleft deformity should be done as it may appear as an isolated deformity or part of a syndrome and have associated systemic anomalies. This may help us to deliver comprehensive care to the patients and can prevent potential operative complications.

Objective: To estimate the maximum voluntary molar biting force (MBF) and incisor biting force (IBF) and their relationship to morphological variables in subjects with different vertical skeletal patterns. Materials and Methods: Maximum voluntary MBF, IBF, and morphological variables were recorded in 120 subjects (60 males and 60 females) with skeletal class I pattern in the age range of 14 to 24 years. All subjects were divided into 3 groups: Normodivergent, hypodivergent, and hyperdivergent, according to the maxillomandibular plane angle and Jarabak ratio. Bite force measurements were undertaken using a custom-made portable digital gnathodynamometer on the left and the right sides of the jaw in the molar and incisor regions during maximal clenching. Statistical analysis was performed using independent t-test, chi-square test, and ANOVA test using SPSS version 22.0.0.0 software. Results: MBF and IBF are influenced by gender with higher values obtained for male subjects in all groups in the following order: hypodivergent > normodivergent > hyperdivergent. No significant changes were seen with morphological variables in different groups. Conclusion: Molar and incisor biting forces are highest in hypodivergent subjects and least in hyperdivergent subjects as a reflection of jaw morphology and muscular efficiency. In all groups, males exhibit higher force values than females, underlining a strong gender influence on biting force and facial pattern.

Objective: Triticeous cartilage is a small ovoid structure belonging to the laryngeal skeleton. When calcified, it becomes visible on panoramic radiographs and be mistaken for a carotid artery calcification (CAC) associated with cerebrovascular accidents. This study aimed to estimate the prevalence of calcified triticeous cartilage (CTC) detected by means of digital panoramic radiographs in a sample of Lebanese population. Materials and Methods: Digital panoramic radiographs of 500 Lebanese adult patients (281 females and 219 males) with a mean age of 47.9 years were included in this study and examined for CTC. The IBM® SPSS® for Windows version 20.0 (SPSS, Chicago, IL, USA) was used to carry out statistical analysis of the data collected. Results: Nearly 10.6% (53 out of 500) of the radiographs examined presented CTC. Of all the calcifications, 11 were on the right side, 5 on the left side, and 37 were bilateral. The cases detected belonged to 31 females and 22 males with an average age of 55.6 years (ranging from 24 to 85 years). Chi-square test did not show any statistical connection between gender and CTC, while Spearman's correlation analysis showed low positive correlation with age (r = 0.146). Conclusion: CTC can be detected on panoramic radiographs taken in daily dental practice; its identification is essential to avoid misdiagnosis with other calcifications in the neck region closely related to life-threatening risks such as CAC.

Abstract Background and aims: The incidence of Coronary Artery Disease (CAD) has reached alanning proportions in India. The pathological hall mark of CAD is myocardial ischemia resulting from the atherosclerotic narrowing of coronary arteries. In this era of advanced interventions and cardiac surgery, a thorough knowledge of normal and variant anatomy of coronary arteries is of prime significance and of great use both to the clinicians and anatomists. Materials and methods: One hundred coronary angiograms of patients free of disease were studied in detail in different profiles. The data obtained was quantified according to their frequencies. The relation between the length of left main coronary artery and coronary artery dominance was statistically analyzed using the 'Chi Square test for Trend'. Results: This study highlighted some interesting findings such as the origin of Sino- atrial nodal artery from the second segment of right coronary artery in 3% of cases, double right marginal artery in 4% cases. Other variations such as Mouchet's posterior recurrent interventricular artery, origin of circumflex artery from the right coronary artery and abnormal communication between the terminal parts of right coronary artery and circumflex artery were each noticed in 1 % of cases. Conclusions: Coronary arteries and their branches are prone to variations in their course and morphology. Prior knowledge about this is important for the interpretation of coronary angiograms and surgical myocardial revascularization. The present work on normal and variant pattern of coronary arteries will help in gathering momentum to the already advancing research work in this field.

Purpose. The aim of this investigation was to evaluate clinically the percentage of permanent mandibular first molar teeth with three roots amongst Palestinian population. Patients and Methods. Three hundred twenty-two mandibular first molars from 185 females and 137 males scheduled for root canal treatment at the Dental Center of the Arab American University were examined over a 2-year period. The incidence of a third root revealed by periapical radiographs and the comparison of the occurrence between males and females and between the right and left sides of the mandible were recorded. Statistical Analysis. It was performed using the chi-square test with a significant level set at P<0.05%. Results. Of the 322 treated mandibular first molars, twelve teeth were found to have a third root with an overall incidence being 3.73%. More teeth with a third root were treated on the right side of the mandible compared to the left side. Conclusion. The incidence of a third root in Palestinian population was within the range of previous reports from the Middle East but considerably lower than the percentage from the Far East.

163 Background: To evaluate whether the systematic 10 cores prostate needle biopsy is enough for determination of NCCN risk classification (NRC), we analyzed migration of Gleason score (GS), cancer location, and NRC between pre and postoperative periods in a cohort of patients who underwent radical prostatectomy. Methods: A total of 197 patients were included in this study. These patients were divided into three groups along the number of biopsy cores: less than 10 (L), 10, and more than 10 (M). We compared between three groups about Gleason score, cancer location and NCCN risk classification change (CC) between prostate biopsy and radical prostatectomy specimen. Statistical analysis were performed with chi-square test, and multiple logistic regression with p<0.05, and Bonferroni correction with p<0.017 considered significant difference. Results: The rate of CC in L, 10, M was 55.1%, 43.0%, 26.5%, respectively. On chi-square test rates of CC were significantly different between three groups (P=0.035), but rates of Gleason score and cancer location were not. On univariate analysis, PSA (Odds rate (OR) 0.872 p<0.001), preoperative NRC (low vs. intermediate, and poor, OR 0.157 and 0.241, p<0.001), prostate volume (normal vs. mild or moderate, OR 1.989 p=0.025), the number of biopsy cores (L vs. M, OR 0.293 p=0.011), GS (6 vs. 8, OR 2.374 p=0.021) were correlated with CC. On multivariate analysis, the most important independent predictive factors for CC were preoperative NRC (low vs. intermediate, p<0.001, OR 0.198, 95% CI 0.09-0.45) and PSA (p=0.007, OR 0.903, 95%CI 0.83-0.98), but the number of biopsy cores was not associated CC significantly. Conclusions: Although multivariate analysis showed no significant difference, the more biopsy cores reduced the risk of CC. Systematic 10 core biopsy might be insufficient for accurate diagnosis and treatment decision of prostate cancer.

OBJECTIVE: This study assessed the anterior-posterior positioning of the upper and lower first molars, and the degree of rotation of the upper first molars in individuals with Class II, division 1, malocclusion. METHODS: Asymmetry I, an accurate device, was used to assess sixty sets of dental casts from 27 females and 33 males, aged between 12 and 21 years old, with bilateral Class II, division 1. The sagittal position of the molars was determined by positioning the casts onto the device, considering the midpalatal suture as a symmetry reference, and then measuring the distance between the mesial marginal ridge of the most distal molar and the mesial marginal ridge of its counterpart. With regard to the degree of rotation of the upper molar, the distance between landmarks on the mesial marginal ridge was measured. Chi-square test with a 5% significance level was used to verify the variation in molars position. Student's t test at 5% significance was used for statistical analysis. RESULTS: A great number of lower molars mesially positioned was registered, and the comparison between the right and left sides also demonstrated a higher number of mesially positioned molars on the right side of both arches. The average rotation of the molars was found to be 0.76 mm and 0.93 mm for the right and left sides, respectively. CONCLUSION: No statistically significant difference was detected between the mean values of molars mesialization regardless of the side and arch. Molars rotation, measured in millimeters, represented ¼ of Class II.
