Gingival overgrowth occurs mainly as a result of certain anti-seizure, immunosuppressive, or antihypertensive drug therapies. Excess gingival tissues impede oral function and are disfiguring. Effective oral hygiene is compromised in the presence of gingival overgrowth, and it is now recognized that this may have negative implications for the systemic health of affected patients. Recent studies ...

During the course of studies on the over-all effects of irradiation on embryonic development, it was observed that tumor-like growths occurred in the head region of rats exposed to x-rays on the ninth day of gestation (6). Although all were probably of neural origin, many of these growths retained no connection with the brain. Disordered growth in the central nervous system, including malformat...

Background: Gingival biotype is one of the most important factors that impede success in dental treatments; it affects the outcomes of periodontal surgery, and restorative treatments. Researchers classified gingival biotypes into thin biotype and thick biotype. It is crucial to identify tissue biotype before treatment. Aim of Study: To determine the prevalence of gingival biotypes in a Syrian p...

Gingival recession is defined as “Displacement of soft tissue margin apical to the cemento-enamel junction”. Gingival recessions require treatment for many reasons – impaired aesthetic appearance, root sensitivity, cervical caries or abrasion. Presence of gingival recession and gingival inflammation in areas with a lack or narrow band of attached gingiva is identified as a mucogingival problem....

We study a competition model on Z where the two infections are driven by supercritical Bernoulli percolations with distinct parameters p and q. We prove that, for any q, there exist at most countably many values of p < min {q,− pc} such that coexistence can occur.

Abstract The ruins of wrecked ships are often so thoroughly dispersed by their submarine environments as to practically vanish. Sometimes, however, the conditions a wreck’s submergence create complex modes material endurance. Concretion, which names both substance that forms on certain immersed surfaces and phenomenon substance’s formation, is one such mode. Inspired maritime-archeological obje...
