The Relationship Between Lips Morphology, Incisors Position and Mandibular Rotation in Adult Skeletal and Dental Class I Individuals (Cephalometric study)

The aim of the study was to evaluate The relation between morphology of lips and incisors and mandibular rotation in adult class Ι individuals and to explore the gender dimorphism for these measurments. Material and methods True lateral cephalometric radiograph of the sample that comprises 32 females and 30 males aged 18-25 years and they possess class I skeletally and dentally. The data were analyzed using independent sample t test and Pearson correlation analysis. Results: In males interlabial angle negatively correlated with U1-NS and positively with U1-L1 Nasolabial angle and mentolabial angle positively correlated with (NS-GoMe, FH-GoMe, B, Bijork angles) Zangle and ULT/ULH negatively correlated with (NS-GoMe, FH-GoMe, B, Bijork angles) in Females lower lip inclination positively correlated with (NS-GoMe, FH-GoMe, B, Bijork angles).

A Study of the Correlation between Lymph Nodes Levels and Characteristics of the Lowe Lip Squamous Cell Carcinoma

Cancer of the lip is relatively common malignancy of the head and neck region. Squamous cell carcinoma most frequently occurs in the lower lip (LLSCC) or Lower Lip Squamous Cell Carcinoma. This study aimed to evaluate the correlation between the involved lymph nodes level and the tumor appearance, greatest dimension (T) and its degree of differentiation.
