Early orthodontic research has focused on the link between face shape and malocclusion. Orthodontic treatment's effectiveness and stability are heavily influenced by a patient's dental and facial anatomy. An orthodontist's knowledge of arch shapes is essential since it affects the patient's treatment and future growth.
For this study, the researchers wanted to see if there was a link between vertical face morphology and arch width, and if there was a difference in arch width between males and females. Arch width measurements (in millimetres) were utilised to determine the association.
For both males and females, participants with the lowest mandibular plane angle had the widest arch, followed by those with the average mandibular angle and those with the highest.
There is considerable interest in the area of orthodontics in malocclusions caused by vertical discrepancies because of their causes, diagnosis, treatment planning, and tendency to return after treatment. Hence, this study aimed to assess, evaluate and check reliability for vertical skeletal discrepancy by establishing a parameter ‘R angle’ in Navi Mumbai population. In this study, the lateral cephalometric radiographs of 135 orthodontic patients between the age group of 18-30 years of age were selected from the database of the Department of Orthodontics and Dentofacial Orthopaedics in D Y Patil University School of Dentistry, Navi Mumbai The study found that the R angle is clinically and statistically important when examining vertical skeletal discrepancies. So with the above results it is observed that R angle can be used to assess vertical skeletal discrepancy in Navi Mumbai population. Along with other parameters it can be important and valuable tool for orthodontist to determine skeletal discrepancies in vertical plane.
Introduction: The largest sinus is the maxillary sinus. The growth and development commence during fetal development (3rd Month) by the infundibulum present on ethmoid bone. Post birth, it expands in the lateral direction during the growth spurt period (Birth - 3 years and 7 - 12 years). Aim/Objectives: The aim was to determine the relation of mandibular body length with the area dimensions of the maxillary and frontal sinus using digital lateral cephalogram. Materials and Methods: 60 Digital lateral cephalograms were equally divided to form 3 groups of Class I, Class II, Class III patients comprising 20 each with equal inclusion of male and female patients. The Dolphin 2017 software was used to calculate the area dimensions and individual variables of both the paranasal sinuses, mandible size and both cranial bases with their growth pattern. Results: Class III malocclusion showed greater dimensions and surface area compared to those in other groups. Mandibular body length showcased a positive correlation to the sinus dimensions. Results obtained showed that the mean value of frontal sinus area for Class I was 335.59 mm2, Class II was 257.64 mm2 and Class III was 393.82 mm2. The mean value of maxillary sinus area for Class I was 973.70 mm2, Class II was 690.48 mm2 and Class III was 1078.75 mm2. Males showed greater values than the female group. Conclusion: Class III malocclusion showed higher values for dimensions and surface area compared to the other sample groups. Values calculated had a positive relation with both the cranial bases and mandibular body size.
With the Global Pandemic of COVID-19 chewing up the headlines and our lives, Dentistry has come to an abrupt standstill. COVID-19 with its affection to salivary glands reforms in orthodontic clinical practice in all aspects from doctor to patient to clinic personnel all will have to change. This article entails just that, the precautions and change in mindset are just the stepping stones to a better and more importantly, a safe practice
