Interdisciplinary dentistry is becoming increasingly common, and cooperation between different dental specialties is essential for proper diagnosis and treatment planning. One such interaction exists between orthodontics and periodontics. In many cases, periodontal health is improved by orthodontic tooth movement, whereas orthodontic tooth movement is often facilitated by periodontal therapy.
The ideal time to commence orthodontic treatment in a growing patient is a controversial issue in the field of orthodontics. In the last two issues, we discussed two major problems: the finger sucking habit and the tongue thrusting habit. Another malocclusion that requires immediate attention is a crossbite.
The term work-related Musculoskeletal Disorders (MSDs) refers to musculoskeletal disorders to which the work environment significantly contributes or that are made worse or prolonged by work conditions or workplace risk factors. Dental auxiliaries, dental hygienists, and dental assistants are prone to work-related MSDs involving the neck, shoulder, wrist, elbow, hand, and lower back, caused by the following risk factors: awkward postures, forceful exertions, repetitive motions, contact stresses, vibration, and the duration of exposure to these risk factors.
105 patients attending the Department of Periodontics at the Tamil Nadu Government Dental College and Hospital in Chennai-03 were screened and selected for the study. Clinical parameters such as plaque index, gingival bleeding index, probing depth, and clinical attachment level were measured. Based on the AAP-1999 classification, subjects were categorized into three groups: Control Group-A (n=35), Study Groups-B (Chronic periodontitis, n=35), and C (Aggressive periodontitis, n=35). Five milliliters of venous blood were drawn from the antecubital vein and transferred to a vacutainer containing EDTA. DNA was isolated by a nonenzymatic method, and the detection of DNA genotype was done using restriction fragment length polymorphism (RFLP) with the enzyme Taq 1. The results were statistically analyzed using Chi-square and odds ratio. The presence of the 't' allele was found to be a risk indicator for the development of periodontal disease. The results showed a positive correlation between the genotype (tt, Tt) and the 't' allele with chronic and aggressive periodontitis, with a higher significance in chronic periodontitis ('tt' genotype = 71.4%, T allele = 82.8%) than in aggressive periodontitis and controls. Taq I VDR gene polymorphism is a strong indicator of susceptibility to chronic periodontitis.
