INTRODUCTION
This study aimed to assess and compare dental arch widths in the anterior and posterior regions among patients undergoing extraction and non-extraction treatments for Class I and Class II malocclusions.
MATERIALS AND METHODOLOGY
A total of 40 patients were selected, with 10 in each of the categorized groups based on malocclusion type and treatment status. Dental arch widths were meticulously measured using a digital Vernier caliper at the canine and molar regions to ensure precise data collection.
RESULTS
Statistically significant differences were noted when comparing mean inter-canine and molar widths between pre- and post-treatment periods among extraction cases in Class I malocclusion (p < 0.001). Conversely, there were no significant changes observed in arch widths among non-extraction cases in Class I malocclusion. Similarly, significant changes were observed in both extraction and non-extraction cases of Class II malocclusion when comparing mean inter-canine and molar widths between pre- and post-treatment periods (p < 0.05).
CONCLUSION
After treatment, both Class I and Class II extraction cases showed an increase in inter-canine arch width, while intermolar arch width remained unchanged, suggesting that the treatment did not significantly alter the buccal corridor. Additionally, there were no notable changes in inter-canine arch widths between pre- and post-treatment in Class I non-extraction cases. However, the Class II non-extraction group exhibited increased upper and lower inter-canine arch widths after treatment.

The size and shape of a tooth vary between individuals of different ethnic groups and genders because of the influence of different genetic factors. The information regarding the different anatomical factors using maxillary anterior teeth is very scanty. Thus to give more clarity, a study was planned to assess the correlation between head circumference and tooth-mesiodistal width among children of different ethnic origins.The study was carried out on 210 children aged 7 to 12 years in schools at Abha, Saudi Arabia.The mesiodistal (MD) width of the central incisor was measured using a digital vernier caliper. A Meter tape ruler was used to measure the Head/Cephalic dimensions. The data obtained were subjected to statistical analysis using IBM SPSS 20.0, and the results were analyzed. It was found that mean MD tooth width and head circumference were maximum in Saudi children, followed by South Asian and Arab/African, with an insignificant statistical difference (-value > 0.05). Correlation between MD dimensions of maxillary central incisor with head circumference was statistically significant (-value < 0.05) among Saudi and South Asian populations, whereas statistically insignificant (-value > 0.05) difference between Saudi and Arab/African populations. It was concluded that there exist the ethnic differences between tooth-mesiodistal width and head circumference dimensions of children. A positive correlation between head circumference and mesiodistal width of the central incisor was determined.

Okra ( (L.) Moecnh) is a versatile crop that is widely grown in western Ethiopia, despite that it is less researched. This study, therefore, investigates the traditional knowledge, nutritional, and morphological characteristics of two commonly grown okra varieties (Kenketse and Sharma) in west Ethiopia. A semi-structured questionnaire, checklist, and observations were used to collect primary data from households, key informants, and farms. In addition, proximate composition parameters like moisture content, total ash, crude fat, crude protein, crude fiber, utilizable carbohydrates, and gross energy fruits were measured through laboratory analysis. Fruit morphological traits, including fruit dimensions such as length and width, were determined using a digital Vernier caliper. For data analysis, SPSS software was used. The results revealed that the entire plant is used for both food and ethnomedicinal purposes. Curing ailments such as stomach pain, constipation, wound/cut, heart discomfort, back pain, malaria, diarrhea, and amoebae were among the medical benefits of okra. The proximate composition (%) on a dry matter basis of okra fruits differed significantly ( < .05) by cultivar type and drying method. Moisture (3.69%-5.24%), total ash (6.60%-8.01%), crude fat (4.87%-8.58%), crude protein (4.06%-5.23%), crude fiber (12.85%-15.26%), utilizable carbohydrate (56.42%-67.63%), and gross energy contents (326-341 kcal) were the ranges of the various proximate and energy levels. Morphological characteristics of fruit and leaf length, width, and length-to-width ratio varied with cultivar type, where Sharma had more than double the length of Kenketse (70.1 vs. 187.1 mm). Despite being an undervalued native vegetable crop in Ethiopia, the study's findings show that okra is a multipurpose vegetable for promoting human health and ensuring food and nutritional security. Therefore, stepping up its production, marketing, and consumption could help alleviate the food shortage and improve human nutrition and health in the study areas.

Introduction Columnar lined epithelium (CLE) of the esophagus holds particular importance in diagnosing Barrett's esophagus (BE). In Asia, the prevalence of BE ranges from 0.06% to 6.2%. In India, prevalence estimates vary from 2.6% to 23%. The frequency of esophageal adenocarcinoma has also been observed to be increasing alarmingly over the past few decades. The length of CLE as a criterion for diagnosing BE is the subject of considerable debate. Changes in CLE length among different age groups may exist. Our study aims to measure the length of CLE, or the distance between the angle of His and the Z Line (AZ distance), in normal individuals from Northeast India, and to analyze its variation across different age groups. Materials and methods The study was conducted in the Department of Anatomy and the Department of Forensic Medicine and Toxicology at Gauhati Medical College, Guwahati, Assam, India, during the period 2017-2019. Once opened, each specimen was laid flat on a board. The distance between the A and Z lines was measured using a pair of vernier calipers. This distance was recorded as the AZ distance in millimeters (mm). Results The mean AZ Distance was found to be 12.4 ± 5.3 mm. A significant correlation between age and AZ distance was observed. Conclusion Our present study suggests that the length of the CLE increases with age. This observation offers an opportunity to revisit or revise the diagnostic criteria based on CLE length, taking into account the age of the individual.

Introduction The knee joint is a complex system containing various hard and soft tissue components necessary for functioning in a coordinated manner. The menisci help to deepen the tibial plateau. Knowledge of the dimension of menisci in the knee joint is of paramount importance in arthroscopic surgery and the management of injuries due to sports or degeneration. The present study aims to describe the morphometric data of the medial meniscus and document the morphometric variation in the medial menisci. Methodology This study was conducted in the department of anatomy in two medical colleges under MGR University by measuring the dimensions of 100 medial menisci taken from 50 formalin-fixed embalmed cadavers. The width and thickness of the medial menisci were measured using digital vernier calipers. The outer and inner circumferences were measured using a measuring tape, non-elastic threads, and metallic pins. The area of the medial meniscus and the tibial plateau was measured by counting the small squares present in the circumference of the menisci drawn over the graph paper. The weight of the medial menisci was measured using the electronic weigh scale. Results The widest part of the medial meniscus was the posterior one-third, and the narrowest part was the anterior one-third. The thickest part was the middle one-third, followed by the anterior one-third. The average inner and outer circumferences of the menisci were 6.25 cm and 10.05 cm, respectively. The medial meniscus covers more than half of the area of the tibial plateau. Conclusion The present study provides a good understanding of the morphometric features of the medial menisci and will be of great help for managing knee joint pathologies and designing prostheses.

BACKGROUND
Ankle sprains are prevalent injuries leading to functional impairment. The lateral ankle ligament complex (LLC), comprising the anterior talofibular ligament (ATFL), posterior talofibular ligament (PTFL), and calcaneofibular ligament (CFL), is weak and prone to injury. The morphometric data of these ligaments are essential for orthopedic practices, including techniques like direct repair or ATFL reconstruction with autograft/allograft, which are limited in the literature. The present study aims to document the anatomy and morphometry of the LLC.
METHODS
Fifteen adult Indian-origin embalmed cadavers were selected for the study. Ankles with antemortem or postmortem injuries or previous surgical interventions were excluded from the study. After precise dissection of the ankle's anterior and lateral aspects as per Cunningham's dissection manual, ligaments were exposed. Length and width were measured using a digital vernier caliper. Morphological attributes such as shape, orientation, and inter-fiber angles were documented.
RESULTS
The most common shape in ATFL was a single band (53.33%). Inner ATFL fibers merged with the ankle joint capsule in 73.33%. ATFL mean length and width were 14 ± 2.4 mm and 7.6 ± 2.0 mm. The angle between the fibula's long axis and ATFL fibers was 107 ± 22°, and the angle between tibiotalar joint lines and parallel ATFL fibers was 30 ± 9.5°. A single band of CFL was predominant (73.33%). The mean length and width of CFL were 18.4 ± 3.9 mm and 5.2 ± 1.3 mm; the angle between the anterior fibula border's long axes and parallel CFL line was 131°. PTFL length was 20.9 ± 3.3 mm and width was 6.2 ± 1.4 mm. The mean length and width of the anterior inferior talofibular ligament (AiTFL) were 11.7 ± 2.6 mm and 9.5 ± 1.6 mm, and of the posterior inferior talofibular ligament (PiTFL) were 12.8 ± 2.1 mm and 10.4 ± 2 mm.
CONCLUSION
Comprehensive knowledge of these ligaments' anatomy and relationships is vital for clinical examination and ultrasonography. Understanding LLC details aids radiologists and orthopedic surgeons in graft selection, sizing, and precise anatomical structure placement during surgical reconstruction.

Background Teeth serve many functions, and aesthetics is one of the most important aspects served by teeth, perceived by the limbic system of the human brain. The golden divine ratio is the unique proportion often correlated with beauty. The present study was devised to estimate the dimension of human permanent canines and approximation to the golden divine ratio. Materials and methods The present study included 47 extracted human permanent canines retrieved from the tooth repository of our institute's Department of Oral Biology. Using digital vernier calipers (Themisto TH-M61 digital vernier caliper, 0-150mm/ 6 inch, JIPVI Ecommerce Pvt. Ltd, India, 2022), the following measurements were taken: Mesio-distal and labiolingual dimensions of the crown, crown length, root length, root to crown ratio (R/C) and the tooth to root ratio (T/R). The data were analyzed using Statistical Package for Social Sciences (SPSS) software version 26. Results All the dimensions' mean and standard deviations were calculated for both maxillary and mandibular canines. While the means of mesio-distal and labiolingual dimensions of the crown approximated the values reported in the literature, there was some variation in crown and root lengths. The mean crown lengths of the upper and lower canines were 10.34mm and 9.76mm, respectively, while the root lengths were 16.52 and 15.54mm, respectively. The R/C of both sets and the T/R of the upper canine only followed the golden ratio. T/R of the lower canine was slightly higher (1.64) Conclusion Although the number of included teeth was less, owing to the fact that canines are rarely extracted, our results provided new values of canines for updation in a unique population. More studies are required for comparative anthropological data updates.

Introduction Golden ratio and beauty are two inseparable sides of the same coin and have been studied for centuries by the Greeks. This divine ratio is defined as an invincible parameter in aesthetic dentistry to measure looks, symmetry, and balance. Being beautiful and handsome also boosts confidence in today's children and therefore is a top priority for young growing kids. However, there is no study done to define facial measurements based on the golden ratio in preschool and school-going children that can succor aesthetics in formative years. The purpose of this research was to evaluate facial proportions in the vertical dimension, quantify them in reference to the golden ratio, and analyze the association with gender among preschool and school-going children of the Santhal tribe in the Bankura district. Materials and methods A total of 399 subjects, 198 children of 3-5 years with primary teeth and 201 children of 6-12 years with mixed dentition, were selected from schools in villages of Bankura district, West Bengal, India. The subjects were made to relax in a sitting position and a digital vernier caliper was used to record the following vertical facial parameters: total facial height (TFH), trichion-gnathion distance (Tr-Gn), and subnasale-gnathion distance (Sn-Gn). The total facial height was correlated with sexual dimorphism and dentition. The ratio of Tr-Sn/Sn-Gn was calculated and compared with the golden ratio. The ratio was classified as normal (if it was between 1.6 and 1.699, i.e., normal to the golden ratio value), long (if it was more than 1.699, i.e., more than the golden ratio value), or short (if it was below 1.6, i.e., less than the golden ratio value). This facial analysis based on the golden ratio was correlated to sexual dimorphism and dentition. The data were recorded, compared with gender, and statistically analyzed using the unpaired t-test and Chi-square test. Results The total facial height was larger in males than females in both primary and mixed dentition; however, the value was highly significant in primary dentition. Tr-Sn/Sn-Gn ratios were lower in the long facial category in both males and females in both preschool and school-going children. The values were statistically significant in these ratios for both dentitions. Conclusion The majority of children in the Santhal tribe of Bankura in West Bengal did not conform to the golden ratio and showed long faces. There was a significant association of facial features with sexual dimorphism. Clinical significance The early prediction of facial features in children and its confirmation with the established golden ratio can be considered an imperative parameter to comprehend facial aesthetics and symmetry.

Comparative Study Randomized Controlled Trial
BACKGROUND AND OBJECTIVES
Prevalence of radiation induced trismus in head and neck cancer (HNC) is 38% to 42% globally. Radiation induced trismus depends on the dosage of the radiation therapy and the surgical procedure. Myofascial release (MFR) and Matrix rhythm therapy (MaRhyThe©) are techniques used to treat the myofascial pain and muscular restriction. The present study aimed to compare the effect of MFR and MaRhyThe© on pain, mouth opening, TMJ disability index (TDI), Gothenburg Trismuus Questionnaire (GTQ), Functional Intraoral Glasgow Scale (FIGS) and quality of life in participants with Radiation induced trismus.
MATERIALS AND METHODOLOGY
About 30 participants in age group of 18 to 65 years diagnosed with radiation induced trismus were included in the study. All the participants were randomly allocated in 2 groups MFR group and MaRhyThe© group. Both the group received structured exercise program. Primary outcomes were Visual Analogue Scale (VAS), Vernier Caliper reading for maximum mouth opening. Secondary outcome measure viz. GTQ, TDI, FIGS and Functional Assessment of Cancer Therapy-Head and Neck (FACT-HN) all obtained values were analyzed at the end of 4th week.
RESULTS
The present study demonstrated significant improvement in terms of reduction in pain, improvement in maximum mouth opening and in GTQ, TMD, FIGS, and FACT-HN scores in all the participants in both group (p ≤ 0.05). However, the groups showed equal effectiveness in the treatment of radiation induced trismus.

BACKGROUND
Minimally invasive periodontic (perio) surgical procedures, piezocision, and micro-osteoperforation are useful techniques for accelerating tooth movement. These techniques also offer advantages in the orthodontic (ortho) and aesthetic domains. This study aimed to evaluate and compare the rates of lower anterior decrowding with piezocision and micro-osteoperforation.
METHODS
This clinical study included 24 patients requiring fixed orthodontic treatments. Two periodontic techniques (piezocision (PZ) and micro-osteoperforation (MOP)) were considered for the orthodontic treatments. Each patient was randomly allocated to either the piezocision (PZ) group or the micro-osteoperforation (MOP) group. The piezocision group received five radiographically guided incisions on the labial surface of the alveolar bone, whereas the micro-osteoperforation group received one to three MOPs each using a mini-implant drill between the six lower anterior teeth, and later, an initial arch wire was ligated to each bracket. Little's irregularity index (LII) was calculated using a digital vernier caliper on study models every four weeks until decrowding was achieved. The difference in the rates of lower anterior crowding between the piezocision and micro-osteoperforation groups was analyzed to determine the statistical significance.
RESULTS
The rates of irregularity index change during decrowding were 4.38 ± 0.61 in the piezocision group and 3.82 ± 0.47 in the micro-osteoperforation group. Piezocision was found to be 1.2 times faster than micro-osteoperforation in terms of the rate of decrowding.
CONCLUSION
The advanced perio-ortho combination technique was advantageous in accelerated decrowding. In comparison to MOP, there was an increase in the rate of decrowding with PZ. Decrowding can be completed quickly with PZ, and it can thus be used to treat crowding effectively in a limited time frame.
