Al-Azhar Journal of Dentistry

Objective: This study was to evaluate the activity of Lactate Dehydrogenase enzymein different tooth malpositions in gingival crevicular fluid (GCF). Patients, materialsand methods: A sample of 18 patients with an age range from 13 to 19years, requiringorthodontic treatment. The study groups were designed into two groups. GroupI: well aligned teeth (control group). Group II: malposed teeth. Group II was subsequentlydivided into 3 sub-groups; Rotation, Spacing and Vertical malposition. Sampleswere collected for assessment of lactate dehydrogenase level in GCF at baseline, oneweek, two and four weeks after treatment. Lactate dehydrogenase was measured inGCF using Enzyme Linked Immunosorbent Assay (ELISA) technique. Results: …
