Stress and Strain Created Around Miniscrews during En Masse Retraction - A Finite Element Method.

Background: En masse retraction of the anterior teeth may create anchorage problems. The effective means of obtaining anchorage in en masse retraction is by the usage of temporary anchorage devices. Aims and Objectives: The purpose of this study is focused on stress and strain created around miniscrew during en masse retraction using the cone beam computed tomography (CBCT) data obtained at two intervals and by the finite element analysis done using the CBCT data obtained. This will show us the stress and strain created around miniscrews and the withstanding capacity of miniscrews. Conclusion: Stress and strain was higher in TADs as compared to cortical and alveolar bone.

Ectodermal dysplasia - A rare case report.

Ectodermal dysplasia (ED) is a rare genetic disease caused by developmental disturbances of embryonic ectoderm derived tissues, organs, and other accessory appendages. The congenital missing of teeth is usually bilateral. Anodontia or hypodontia may be associated with other ectodermal disturbances, such as anhidrosis, asteatosis, hypotrichosis, and salivary glands defects. One such case report of ED is demonstrated here.

Nifedipine induced gingival enlargement in an edentulous patient: a case report with one year follow up.

BACKGROUND: Gingival enlargement due to calcium channel blockers is a common complaint reported by patients. It can be localized or generalized and can range from mild to severe, affecting patients appearance and function. Nifedipine induced gingival enlargement is noticed only in 10 % of patients and very few cases of Nifedipine induced gingival enlargement in an edentulous patient have been documented in the literature. CASE PRESENTATION: Here in, we report a case of gingival enlargement in a 70 year old hypertensive edentulous patient who was on low dose Nifedipine therapy. Patient wanted complete dentures. We planned to excise the overgrowth and followed up for 1 year. CONCLUSION: Nifedipine induced gingival enlargement noticed only in 10 % of patients. Hence, there is a need for physicians and dentist to make a coordinated treatment plan and practice care while prescribing these drugs which are associated with gingival overgrowth.
