Correlation between vertical dimension of occlusion and length of fingers in dentate subjects.

Objective: To determine whether there is a correlation between finger length and the vertical dimension of occlusion in dentate individuals attending the prosthodontics department at Muhammad Dental College, Mirpurkhas.Methodology: During this cross-sectional study 2023-2024, 218 patients with crown & bridge were included. Clinical an-thropometric measures were taken. The subjects received instructions to softly bite on their back teeth, keep their lips in passive contact, and keep their heads well-stabilized in order to retrieve the VDO. A Vernier caliper was then used to measure the distance. Each parameter was measured three times and average value was recorded.Results: Average age of the patients was 25.39±2.58 years. The parameters for index finger length (r=0.669; p=0.0005), little finger length (r=0.666; p=0.0005), and the length of the tip of the thumb and the index finger (r =0.663; p=0.0005) had the highest correlations with VDO.Conclusion: It is concluded that this procedure is simple, cost-effective, and non-invasive, therefore it might be used in routine practice to ascertain the vertical dimension of occlusion.

An Association Between Left-Hand Digit Ratio (2D:4D) and Anthropometric Indexes in Chinese Children and Adolescents Aged 8-15 Years in Bengbu City.

The digit ratio (2D:4D) is a possible marker of prenatal hormone exposure. The purpose of this study was to explore the relationships between digit ratio (2D:4D) and anthropometric indexes in Chinese children and adolescents. This study is a cross-sectional study. A school-based survey among 685 children and adolescents aged 8-15 years were conducted by stratified cluster sampling. The length of index finger (2D) and ring finger (4D) of the left hand, height, sitting height (ST), weight, chest circumference (CC), waist circumference (WC), hip circumference (HC), and abdominal skinfold thickness (AST) were measured. Pearson correlation and multivariate linear regression were used to analyze associations between 2D:4D and above indexes. In girls, 2D:4D was positively related to WC, AST, waist-to-height (WHtR), waist-to-hip ratio (WHR) after adjusting for ages (p < 0.05). The WC, AST, WHtR, and WHR among girls with 2D:4D ≥ 1 were significantly higher than those among girls with 2D:4D < 1, respectively (p < 0.05). However, there was no correlations between digit ratio (2D:4D) and above anthropometric indexes in boys (p > 0.05). The 2D:4D was related to anthropometric indexes in girls, which suggests that the maternal prenatal hormone exposure might be related to the anthropometric indexes of their female offspring.

Application of the Length of Index and Ring Fingers to Estimate the Stature.

Stature contributes as a crucial element of an individual's physical appearance and can be instrumental in establishing their identity.In cases where the body is extensively mutilated, decomposed, or reduced to skeletal remains, stature becomes an essential component in identifying the unknown by means of measuring the skeletal remains. Its estimation relies on the principle that an individual's height has a definite and linear relationship with specific body parts and long bones. This process, together with assessing age, sex, and race constitutes the essential components of the anthropological protocol. Stature estimation can be accomplished through both anatomical and mathematical approaches. The present study clearly defines regression models for height estimation from finger lengths. The formula derived can proveparticularly valuable in Medico-legal scenarios, as it can be applied effectively even when only a portion of the body is accessible. The purpose of the present study is to estimate the stature of individuals by measuring the length of the index and ring fingers. The current study acquired three measurements, such as stature, right/left index finger length (RIFL/LIFL), and ring finger length (RFL), from 220 samples, including 110 males and 110 females, respectively, between the age groups of 20 and 60 years. The application of the length of the index and ring finger in forensic investigations holds significance due to their potential as reliable predictors of an individual's height. According to the findings of the study, males showed significantly higher stature than females. A statistically significant correlation was also observed (p-value = 0) between stature and finger lengths (IFL, RFL) in both hands. The highest correlation coefficients were found for the left RFL (r = 0.688) in females and the LIFL (r = 0.552) in males. Additionally, males showed significantly longer index and RFL than females. Linear regression models for the estimation of stature from ring and index finger length were also derived successfully. The results obtained from the present study exhibit potential use to evaluate the utility of measuring index and RFLs for determining stature and predicting the precision of regression models by employing those parameters. The models derived from this study can serve as corroborative evidence for identifying mutilated body parts or unknown remains.

Exploratory analysis using machine learning algorithms to predict pinch strength by anthropometric and socio-demographic features

Objectives. This study examines the role of different machine learning (ML) algorithms to determine which socio-demographic factors and hand–forearm anthropometric dimensions can be used to accurately predict hand function. Methods. The cross-sectional study was conducted with 7119 healthy Iranian participants (3525 males and 3594 females) aged 10–89 years. Seventeen hand–forearm anthropometric dimensions were measured by JEGS digital caliper and a measuring tape. Tip-to-tip, key and three-jaw chuck pinches were measured using a calibrated pinch gauge. Subsequently, 21 features pertinent to socio-demographic factors and hand–forearm anthropometric dimensions were used for classification. Furthermore, 12 well-known classifiers were implemented and evaluated to predict pinches. Results. Among the 21 features considered in this study, hand length, stature, age, thumb length and index finger length were found to be the most relevant and effective components for each of the three pinch predictions. The k-nearest neighbor, adaptive boosting (AdaBoost) and random forest classifiers achieved the highest classification accuracy of 96.75, 86.49 and 84.66% to predict three pinches, respectively. Conclusions. Predicting pinch strength and determining the predictive hand–forearm anthropometric and socio-demographic characteristics using ML may pave the way to designing an enhanced tool handle and reduce common musculoskeletal disorders of the hand.

Gender Determination Using Index and Ring Finger Linear Measurements in North Indian Population: A Cross-Sectional Study.

In the fields of medico-legal matters and bio-archaeological settings, gender evaluation plays a pivotal role in the initial stages of human identification. Approximately half of the population at risk is excluded when gender is determined, making it the most essential factor for identification. When it comes to medico-legal matters and bio-archaeological settings, gender evaluation is a crucial initial step in human identification. Traditional gender determination procedures, such as skull and pelvic analysis, may be hindered by fragmentary human remains that have been degraded by various forms of inhumation or physical assaults. To investigate sexual dimorphism, this study examined the ratio of index finger length to ring finger length. The lengths of the index and ring fingers were measured and the ratios between them were calculated for both hands separately. Applications of IBMSPSSStatistics for Windows, Version 16.0 (Released 2007; IBM Corp., Armonk, New York, United States) included Student's t-test and Levene's test. According to the study, women's index finger-to-ring finger length ratios were much longer than men's. The ratio of index finger to ring finger length was significantly different between the sexes on both sides of the hand (p<0.001). In terms of the right hand, the threshold value was 0.9666 for men and 0.9952 for females, while in terms of the left hand, the values were 0.9638 and 0.9920, respectively. With an advancing front in this arena on gender determination, the use of digits has become an additional source of support to physical anthropologists for bio-archaeological surveys and to forensic experts for use in medico-legal investigations for fragmentary remains received during investigatory trials.

The effect of testosterone level on metabolic syndrome: a cross-sectional study.

Metabolic syndrome (MS) may reduce circulating testosterone and, at the same time, low testosterone levels may lead to MS. Thus, identifying problems regarding sex hormones and examining their effects on the pathogenesis of MS is important to prevent serious complications of the condition, such as diabetes or cardiovascular diseases. This study aimed to investigate the correlations between MS-related parameters and androgen levels. A total of 108 males [median age 48.5 years (min/max = 21/77 years)] were included in the study. Blood pressure and anthropometric measurements (body mass index, waist circumference, hip circumference, thigh circumference, neck circumference, and length of index and ring finger) were performed. Biochemical analysis was assessed. Additionally, total testosterone, free testosterone, and sex hormone binding globulin levels were investigated. Weak negativecorrelations were observedbetween testosterone levels and several anthropometric measures/glucose metabolisms (p < 0.05). The highest correlation was between total testosterone levels and body mass index (rho= -0.390, p < 0.001) CONCLUSION: According to our results, controlling weight, one of the preventable risk factors, can have a positive effect on testosterone levels and, therefore, on the cardiovascular system through different mechanisms.

An Observational Study to Standardise the Bindu Pramana in Nasya Karma

Ayurveda is the science of life consisting of guidelines for the maintenance of health and to cure the disease. A Vaidya based on his yukti treat the patients by using different modalities of treatment explained by our acharyas. Shodhana and shamana are the 2 main domains of treatment. Shodhana comes under panchakarma which consists of mainly vamana, virechana, basti , nasya. These treatment modalities yield optimum results only when it is administered with due consideration to matra and kala. Nasya karma is one among the panchakarma therapy which deals with the diseases of jatrurdhva. The dose of Sneha nasya is explained in bindu Pramana. Now a days practically bindu is considered as one drop. But our acharyas clearly explained the procedure for measurement of bindu Pramana to obtain the optimum results. The dose of bindu Pramana varies from person to person. materials and methods:- In the present study 40 healthy volunteers are selected between the age group of 20-30 and the bindu Pramana is measured as per the classics considering the BMI, Length of index finger , circumference of index finger for measuring 8 bindu pramana of murchita tila taila and mahamasha taila. The mean dose of 8 bindu Pramana for murchita tila taila is 5.31ml and the mean dose of 8 bindu Pramana for mahamasha taila is 5.43ml. conclusion:- Based on the results we can conclude that drop is not equal to bindu and the measurement of bindu depends on the individual. hence calculation of right dose of medicine is required to obtain the optimum results.

RELATIONSHIP OF THE VERTICAL DIMENSION OF OCCLUSION WITH ANTHROPOMETRIC MEASUREMENTS OF FINGER IN INDIVIDUALS OF KERALA POPULATION - A CROSS-SECTIONAL STUDY

Aim: The aim of this study was to find out the correlation of vertical dimension of occlusion with anthropometric measurements of finger in individuals of kerala population, which can be used as future reference of the vertical dimension of occlusion (VDO) and hence can be used to determine VDO in edentulous patients. Materials and Methods: The study was conducted in the Department of Prosthodontics, Govt. Dental College, Kottayam, kerala, India. A total of 240 dentate subjects of age range 20 to 40 years were included for this study.Anthropometric measurements of VDO, length of index finger, length of little finger and distance from tip of thumb to tip of index finger of right hand was recorded clinically using modified digital vernier caliper with an accuracy of 0.01 mm. For all the parameters of this study mean, standard deviation and range was calculated. Correlation was studied using Pearson Correlation Coefficient method (whendistribution was normal).Spearman correlation was used when distribution was not normal. Results: In males, correlation ofVDO was strongest for the parameter - length of index finger (r-0.659). In females correlation of VDO was strongest for the parameter - length of little finger (r-0.723). Conclusion: Within the limitations of the present study, the result shows that the index finger and little finger can be used as an adjunct for determining the VDO in edentulous male and female patients respectively.

Correlation of index finger length to vertical dimensions of occlusion for edentulous patients and their satisfaction: a randomized controlled trial

The prevalence of edentulism is pandemic and people resort to complete dentures for the restoration of missing teeth and esthetics. However, the determination of the correct occlusal vertical dimensions (OVD) constitutes to play an important role in overall patient satisfaction. The objective of this study was to apply anthropometric methods to correlate the length of index finger (2D) to measure the OVD from base of the nose to the base of the chin (Sn–Me) and to assess satisfaction by comparing both the methods. A total of 80 edentulous patients were randomized and controlled for this trial into experimental and control groups. A correlation was found between Sn–Me and finger measurements, dentures’ satisfaction was assessed after a 1-week follow-up and marked according to the Visual Analog Scale. Our findings established that finger measurements are greater among males, and in both genders, positive, and statistically significant correlations exist between the facial and finger length measurements. Moreover, 97.0% patients from experimental group were satisfied with the use of complete dentures through the new anthropometric method. Hence measuring the length of index finger can be an adjunct method for the restoration of OVD and is a relatively time-effective and simple method with a satisfactory follow-up.Trial registration: ID: NCT05153213 (https://clinicaltrials.gov/ct2/show/NCT05153213).

Determination of Gender from Index and Ring Finger Ratio in Young Adult

Introduction: Forensic anthropologists are mostly involved in establishing human identification of unknown dismembered remains, especially during the global humanitarian and medico-legal crisis. Methods: A cross-sectional study was conducted on 250 adults (105 males and 145 females) Nepalese adults in the age group of 20-25 years were studied to investigate sexual dimorphism of the index and ring finger ratio. Results: The difference between the mean 2DL in males and females was 0.58 in the right 2DL and 0.6788 in the left 2DL. Similarly, it was 0.684 in the right 4DL and 0.714 in the left 4DL which showed not much difference significantly. The index and ring finger ratio is derived by dividing the index finger length by ring finger length Percentage accuracy based on sectioning point analysis in right-hand male was 99.16% and left hand was 99.84% similarly in the female right hand was 99.85% and left hand was 99.46%. Conclusions: Unlike previous studies, the difference in the length and ratio of the index and ring fingers was not significant between males and females. To generalize the findings, a similar study with a larger sample size is advised.

Normative Data on the Maximum Twisting Force for an Elderly Person’s Sustainable Life

Most elderly people have difficulty opening a new bottle cap due to the insufficient torque to be applied. The study aims at obtaining normative data on the hand dimensions and the maximum torque that could be generated by elderly persons. This study was conducted on 30 elderly people aged 60 and over. A digital torque meter, digital caliper, and tissue tape were used to measure the maximum torque on a dummy bottle and hand dimensions. SPSS software was used for all statistical analyses. Older men have been found to have larger hand dimensions than older women. However, no significant differences in hand dimensions were found between different age groups. A statistically significant difference was observed between the age group 60–69 years vs. 80–89 years and the age group 70–79 years vs. 80–89 years in maximum torque. The correlation between hand dimensions (thumb width and index finger length) and maximum torque was highly correlated (r = 0.63 and r = 0.62, respectively). Knowledge of the relationship between hand dimensions and maximum torque can be used for future bottle cap designs to meet the needs of the elderly.

Stature Estimation from Finger Length by Regression Equation

Background: Estimation of stature from mutilated body parts, as in mass disasters and in many heinous crimes, has always intrigued the Forensic Pathologist and investigating agencies. Every part of human being grows in correlation to each other. Many authors have conducted various studies to find the correlation amongst various body parts and found positive correlation. The present study has correlated the length of all fingers with the stature of the individual. Methodology: The study was carried out on 150 healthy voluntary subjects (75 male and 75 female) of age 18-25 years. Instruments like Stadiometer and Vernier caliper was used for height and finger length measurements respectively. Result: Mean values of stature and finger length were larger in males as compared to females. Positive and strong correlation was found between stature and right index finger length in females and left middle finger length in males whereas right and left middle finger length in total subjects showed statistically significant correlation (P-value &lt; 0.05). Conclusion: The findings of the study can be useful only when an intact finger is examined. As very less information is available related to correlation between finger length and stature of individual, there is need of more research from different geographical locations.

Prediction of Stature from Index Finger Length in South Karnataka Population: A First Radiographic Study

Context: The “big four” components of biological profile are age, sex, race, and stature. Stature estimation is considered as one of the most important biological profiles for identification of an individual. Aims: We aimed to estimate stature from index finger length (IFL) clinically and also radiographically in South Indian population. Subjects and Methods: A cross-sectional sample of 100 patients was randomly selected from patients who visited the Department of Oral Medicine and Radiology in our institution. Stature of the participants was measured using a height chart ruler. IFL was measured clinically using digital calipers. Handwrist radiographs of the left hand were obtained using the KODAK 8000C Panoramic and Cephalometric System. Radiographic measurements were taken from the line joining the metacarpophalangeal joint to the distal point on the distal phalange of the index finger done using Windows Trophy DICOM software. Statistical Analysis Used: Data were subjected to logistic regression analysis. Results: Significant correlation was found between IFL and stature both clinically and radiographically. Conclusions: The use of IFL can be recommended to predict stature. Even if the soft tissues undergo putrefaction, the radiographs can help in assessing the stature of the individual and can provide an advantage of time in comparison to estimation of stature clinically.

Estimating Stature among Medical Students in Lalitpur, Tertiary Care Hospital, using Index and Ring Finger Length

Estimating Stature among Medical Students in Lalitpur, Tertiary Care Hospital, using Index and Ring Finger Length

Getting the size right: Are clinicians ready for it?

ObjectivesDigital examination has many uses in obstetrics and gynaecology, including cervical assessment in labour and measuring for vaginal pessaries. Clinicians must be adequately trained to perform accurate digital assessments and use this information to make decisions.We aimed to evaluate the accuracy of a clinician’s estimate for three different measuring tasks and assess whether there was any difference in the accuracy in relation to seniority or job role. Study designDoctors and midwives were recruited from two perineal trauma training events. Estimates and measurements for three different activities were recorded: length of own index finger, length of an anal sphincter model and cervical dilatation at two different dilatations (7 cm and 9 cm) using a pocket guide cervical dilatation tool. The results were analysed for accuracy of measurements according to job role and seniority. ResultsA total of 369 participants took part. Only 4.6% of participants accurately (to 0.1 cm) estimated the length of their index finger (0% of midwives and 5.5% of doctors). There was a significant difference (p < 0.05) when comparing average differences between estimated and actual lengths measured for doctors and midwives for almost all measurements. When comparing doctors based on seniority there was no significant difference in the accuracy of estimated lengths. A higher percentage of midwives than doctors were accurate at both 7 cm (22% vs 16.1%) and 9 cm (30.5% vs 29.5%) dilated. ConclusionWe found that accuracy was poor for both doctors and midwives when asked to estimate various measurements. We suggest that training will improve awareness of finger length and therefore improve accuracy when performing digital examinations in clinical practice.

A highly significant (p&lt;0.001) positive correlation was found between stature and right index finger length 0.571 and left index finger length 0.576 in Chakma males. The stature and right index finger length 0.630 and left index finger length 0.679 in Chakma females respectively. Conclusion: This study found multiplication factors for right and left index finger length to estimate stature in a correct way and found a linear correlation between stature and index fingers length. There was significant gender difference present between index fingers length in between adult Chakma males and females. IAHS Medical Journal Vol 5(1), June 2022; 22-26

Prepartum and Postpartum Evaluation of Internal Genitalia of Red Sokoto Goat Does Using Digital Rectal Palpation Technique

Study was aimed at determining prepartum and postpartum transrectal palpability of segments of internal genitalia of Red Sokoto Goat (RSG) does using digital rectal palpation technique. Weekly transrectal palpation of 50 does was performed prepartum for nine weeks using digital rectal palpation (DRP) technique with index finger to determine prepartum transrectal palpability. Transrectal measurement of width and length of genital segments was carried out on 26 does using DRP technique with index finger that had predetermined width and length. Twenty eight does that were cycling and with normal reproductive tract were selected and divided into artificial insemination (n = 14) and natural service (n = 14) groups indicating the method of breeding used. Body condition score (BCS) was measured. Determination of postpartum transrectal palpability and measurement of width and length of genital segments was performed on 26 does that kidded using DRP technique with index finger that had predetermined width and length. Evaluation was carried out on day 7, 14, 21 and 28 postpartum to palpate, measure genital segments and assess uterine involution. Length of index finger was 9.0 cm. Prepartum palpability of vagina, cervix, uterus, oviduct and ovary was 449 (100%), 433 (96.4%), 401 (89.3%), 0 (0.0%) and 207 (46.2%), respectively. Detection of uterus and ovary decreased with increasing BCS with P &lt; 0.05 association. Mean values for width and length of uterus was 2.67 ± 0.25 cm and 5.22 ± 0.49 cm, respectively. Postpartum palpability of vagina, cervix and uterus was 104 (100%) day 7, 14, 21 and 28. Width and length of uterus on day 28 postpartum was 2.70 ± 0.08 cm and 6.21 ± 0.60 cm, respectively. Conclusion: vagina, cervix, uterus and ovary were transrectally palpable prepartum and postpartum using DRP technique with index finger; postpartum width and length of uterus on day 28 indicate completion of postpartum uterine involution in RSG does.

Cross Sectional Study on Estimation of Stature from Index, Middle and Ring Finger in Adult Population of Hyderabad Telangana.

Cross sectional study on estimation of stature from length of fingers (Index, Middle and Ring finger of both the hands) was conducted on 150 individuals in the region of Hyderabad, Telangana. Study results showed that there is a significant correlation between length of fingers and stature, Index and middle finger lengths are more reliable than a ring finger length was observed in our study. The height of the individual is approximately 23 times the length of the ring finger, 21 times the length of the middle finger and 22 times the length of the index finger. Standard error of 1.34 to 1.60, R square less than 0.5 and P value less than 0.001 shows statistical significance of our study. The data was statistically analyzed by using SPSS (version-25) software. The formula for linear regression for estimating the height is y = a + (b x).Regression formulae for total population for right index finger is y = 69.75 + (13.75 x), left index finger is y = 66.05 + (14.15 x), right middle finger is y = 63.75 + (13.21 x), left middle finger is y = 62.79 + (13.25 x), right ring finger is y = 71.88 + (13.24 x) and left ring finger is y = 71.84 + (13.22 x). A separate linear regression equation for male and female found more accuracy than equation for total population was observed in our study. Calculated statures from these equations are close to the actual height, only ±5cm difference was observed in most of the individuals.

Prevalence of Some Common Human Traits: An Updated Survey Report From Rajshahi University Campus, Bangladesh

Prevalence of some common human traits viz., body weight, height and body mass index (BMI), pattern baldness, body hair, chin, colour blindness, cheek dimples, earlobes, length of index finger, lips, nose, polydactyly, tongue and widow’s peak, and ABO blood groups along with their Rh-D antigen, were recorded and analyzed from 500 male and 1000 female students of the Rajshahi University (RU) Campus. Results showed that body weights of the male students (66.42±8.92 kg) were significantly higher (t= 35.14; P&lt;0.001) than those of the female students (51.64±6.97 kg). The differences in BMI between males (23.32±3.26) and females (20.85±2.63), as expected, were also highly significant (t= 15.79; P&lt;0.001) and notably, some of the female students were underweight (BMI&lt; 18.5). No female had baldness compared to 15.8% bald males. Sparse body hair was prevalent over the dense body hair in both genders. The females had much higher smooth chin (89.6%) than the males (58.0%) but the males had much higher cleft chin (42.0%) compared to the females (10.4%). No female was colourblind whereas 7.4% males were colourblind. Absence of dimples was recorded in 92.4% males and 85.7% females. Attached earlobes were higher than the free earlobes in both sexes. Compared to the length of the ring finger, shorter index finger was prevalent both in males (85.4%) and females (68.6%). Frequencies of the broad lips in males and females were 53.4% and 58.6%, respectively. Females dominated large and broad noses (76.1%) in comparison with their male counterparts (61.4%). Polydactyly was a rare trait in the Campus, where only 2.2% males and 0.2% females had extra digits in their hands or feet. Tongue rollers (53.8%) outnumbered the tongue folders in males, but tongue folders (54.4%) outnumbered the tongue rollers in females. Males with widow’s peak were higher (25.8%) than that in the females (19.0). Blood groups in the males and females were in the order: B (32.0) &gt; O (29.8) &gt; A (22.4) &gt; AB (15.8) and O (34.8) &gt; B (34.4) &gt; A (21.9) &gt; AB (8.9), respectively. As a whole, 85.4% males and 98.0% females were Rh-positive where the blood group phenotypes did not affect body weight, height and BMI of the subjects (r=0.012; P=0.63). The relevance of these findings to the physical, physiological, social and clinical well-being of the humans has been discussed. Bangladesh J. Zool. 49 (2): 215-228, 2021
