Objective: Evaluation of the effectiveness of vestibuloplasty according to microhemodynamics and oxygenation in the mucous membrane of the alveolar ridge.
Materials And Methods: To achieve this goal, a clinical and functional study was carried out in the mucous membrane of the alveolar ridge after vestibuloplasty in 80 patients (35 men and 45 women) aged from 18 to 65 years, average age 41.5±1.

The Charles procedure (CP) is a potentially devastating treatment; however, in cases of an end stage of untreated or improperly treated lymphedema, it is the ultimate surgical therapy. As a life-saving solution, it quickly relieves patients with giant, hypertrophic extremities, mostly in ambulation and hygiene maintenance. Nevertheless, long-term results may disappoint both doctors and patients, who struggle with social stigma, the need for lifelong compression, massive lymphoedema in the distal parts of the feet, badly fitting shoes, excessive skin fibrosis, severe keratinization of skin-grafted surfaces, periodic lymphorrhea from the resected areas, or acute and chronic inflammation.

Methods: The L*, a* and b* color coordinates were measured in 60 adult participants (30 with an ISFP and 30 with healthy teeth and gums) using a Spectroshade™ Micro spectrophotometer. From these coordinates, the changes in lightness (ΔL'), chroma (ΔC') and hue (ΔH') CIEDE2000 between the participants with and without an ISFP were quantified.

Purpose: Carcinogenesis is characterized by the transformation of normal cells into malignant cells. Concerning the lower lip, exposure to UV radiation is the main etiological factor associated with the development of epidermoid carcinomas and actinic cheilitis. According to the hierarchical model theory, cancer development is driven by populations of cancer stem cells.

squamous cell carcinoma is a recently recognized entity characterized by a non-viral-related non-keratinizing squamous cell carcinoma with chromosomal rearrangement between on 6p22.3 and on Xq28. This neoplasm is associated with an aggressive clinical behavior, particularly regarding local recurrences and distant metastases even with its deceptively bland histomorphology.
