Oral squamous cell carcinoma (OSCC) is a prevalent and lethal malignancy with a diverse etiology. LINC00312 is a long intergenic non-coding RNA that functions as a signal hub to regulate the progression and treatment of head and neck cancer. The aim of this study was to evaluate the effect of single nucleotide polymorphisms (SNPs) on the development of oral cancer. Two SNPs, namely rs12497104 and rs164966, were investigated among 469 male patients with cancer of buccal mucosa and 1194 gender- and age-matched controls. No significant correlation was observed between these two SNPs and the occurrence of OSCC in the case and control groups. While assessing the clinicopathological features, carriers of at least one minor allele of rs164966 (GA and GG) were less prone to develop lymph node metastasis (adjusted odds ratio [AOR], 0.666; 95% confidence interval [CI], 0.447-0.991; =0.045) in comparison with homozygous carriers of the major allele (AA). Subsequent stratifying surveys revealed that this genetic association with nodal spread was seen only in cases who habitually chewed betel quid (AOR, 0.616; 95% CI, 0.386-0.985; =0.042) or smoked cigarettes (AOR, 0.612; 95% CI, 0.393-0.953; =0.029), but undetected in cases free of these main behavioral risks. Our results indicate an interactivity of rs164966 with lifestyle-related risks on modulating OSCC progression.

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.

Juvenile scleroderma (JS) is a rare chronic connective tissue disorder characterized by stiffening of the skin and soft tissues, including the oral cavity and perioral tissues, leading to fibrosis and a large spectrum of internal organs involvement, cosmetic defects, and early infant disability. The aim of this study was to investigate the histomorphological features of lesions of oral mucosa tissues in children with juvenile scleroderma (JS). 39 JS patients (9 with juvenile systemic sclerosis - JSS and 20 with juvenile scleroderma of head-JSH aged from 5 to 17 years were observed with dental examination and morphological investigation of the dental mucosa.

Background: Hybrid Odontogenic Tumors (HOT) are defined by the presence of two or more independent odontogenic tumors that originate from and affect the same maxillofacial site.
Methods: The present study is the first case report of a mandibular HOT consisting of Ameloblastoma, Calcifying Epithelial Odontogenic Tumor, and Ameloblastic Fibroma.
Case Report: A 37-year-old otherwise healthy male presented with the chief complaint of swelling in the right mandibular body.
