Purpose: The most common techniques to reconstruct the urethra for severe hypospadias or epispadias involve use of the genital skin. Buccal mucosa free graft is usually used in a second operation due to a paucity of usable genital tissue. We report our experience using buccal mucosa free graft as primary surgery for hypospadias and epispadias.
Materials And Methods: Between 1989 and 2001 the urethra was reconstructed using buccal mucosa free graft as a primary operation in 22 patients 3 to 13 years old with middle or proximal hypospadias (20) and exstrophy/epispadias (2). In the first 5 cases of hypospadias the buccal mucosa was combined with bladder mucosa. In the 2 exstrophy/epispadias cases treated with the penile disassembly technique the distal part of the urethra was reconstructed with buccal mucosa.
Results: At mean 5-year followup 2 cases of urethral fistulas and 1 case of severe stenosis of the proximal anastomosis were observed, which required surgical correction. In 4 other cases mild stenosis of the anastomosis required urethral dilations in the first month after surgery.
Conclusions: Buccal mucosa is an excellent source of graft material for urethral replacement in complex urethroplasties as primary surgery. It is readily available, elastic, resistant and technically easy to harvest.

Oral submucous fibrosis (OSF) is a chronic, progressive, and fibrotic condition of the oral mucosa that carries an elevated risk of malignant transformation. We aimed to identify and validate novel genes associated with the regulation of epithelial-to-mesenchymal transition (EMT) in OSF. Genes regulating EMT were identified through differential gene expression analysis, using a LogFC threshold of -1 and + 1 and a padj value < 0.

Objective: The study assessed the prevalence and clinical implications of Epstein Barr Virus (EBV)-positive but Human Papillomavirus (HPV)-negative oral squamous cell carcinoma (OSCC) in a tertiary care hospital setting. The overall goal was to elucidate the potential impact of EBV on OSCC disease progression and prognosis.
Design: A total of 134 surgically resected and histopathologically confirmed OSCC tumor biopsies were collected from a tertiary care hospital.

Molar incisor hypomineralization (MIH) is a developmental defect that affects the enamel tissue of permanent teeth. Clinicians may observe a range of opacities in the affected teeth, varying from white to creamy, yellow, and brown. Of particular interest is an etiology of MIH that has not been rigorously elucidated.

Objective: To compare the influence of different emergence profile of implants in mandibular molar on the peri-implant soft tissue.
Methods: Forty-four implants were divided into two equal groups by mucosal thickness, ≥2 mm (group A) or < 2 mm (group B), and were randomly included in the test group and the control group. In the control group, the patients were treated by a prosthesis with no transmucosal modifications (subgroups A1 and B1).

We have studied the presence and frequency of micronuclei in exfoliated oral mucosa cells of full-term newborns and their association with maternal prenatal factors. We report an analytical, observational, cross-sectional, prospective study that includes 97 preterm infants (<37 weeks), 37 newborns from mothers with comorbidities, and 60 newborns from mothers without comorbidities, in a tertiary public hospital. Oral mucosa cells were collected within 24 h after birth.
