Abstract:

Head and neck cancer is a term used to describe a number of different malignant tumors that develop in or around the throat, larynx, nose, sinuses, and mouth. Laryngeal cancer is cancer of the larynx, which is a part of the throat.

Successful management of laryngeal cancer depends on careful pretreatment evaluation of the patient, and  appropriate treatment selection for patients with this disease.

Management of the head and neck cancer patients requires a multidisciplinary team. Treatment  includes radiation, chemotherapy, and surgery.  Patients with malignant disease need careful dental treatment planning prior to radiation therapy  and/or chemotherapy. In this presentation, we  report a case of a patient with laryngeal cancer, who did not have a chance to follow dental treatment recommendations for both pre- and post radiation dental management. The aim is to create awareness for the clinician to evaluating the patient for the disease related issues that may affect the oral cavity and dentition, and to know what treatment options do we have in this case. The treatment option used in this case for oral rehabilitation and improvement of his quality of life.

Abstract:

Introduction: Implication of human papilloma virus (HPV) in the carcinogenesis of oral squamous cell carcinoma (OSCC) is debatable subject, p16 overexpression indicates active HPV infection in oropharyngeal squamous cell carcinoma (OPSCC) but in OSCC such relation still needs to be studied. Therefore, we aimed to evaluate the frequency of HPV in OSCC patients in the capital of Kurdistan region of Iraq and its concordance with p16 overexpression. We retrieved Eighty-six formalin-fixed paraffin-embedded (FFPE) samples of OSCC from multi large pathological centers that located in the capital of Kurdistan, we utilized immunohistochemistry (IHC) to detect the HPV by anti-HPV high risk antibody correlated it with p16 overexpression, besides, twenty FFPE samples of healthy gingiva were used as control in this study. Chi square and Fisher’s exact tests were used for correlating the HPV status and p16 overexpression with clinicopathogical patient’s data. The concordance between HPV and p16 overexpression was evaluated by kappa agreement and spearman rank correlation. The frequency of HPV in OSCC patients were 15.1%, tongue was the most common site affected by HPV infection, other patient data including age, gender, grade and stage did not show significant correlation with neither anti-HPV nor P16 antibodies. The concordance level between p16 overexpression and the HPV status according to kappa agreement was (κ = 0.221, p= 0.034), Moreover, the correlation according to spearman correlation coefficient was (r = 0.229, p= 0.034), with 46.15% sensitivity and 80.82% specificity. We concluded that HPV infection is still low in Erbil and p16 biomarker has only diminutive significance as a predictor of HPV infection in the OSCC patients.

Abstract:

Statement of the Problem: One of the anatomical obstacles for dental implants placement in the upper jaw is the nasopalatine canal. The neurovascular contents include nasopalatine nerve, terminal branch of nasopalatine artery and anastomoses with greater palatine nerve and artery. This gives innervation and vascularization for the upper anterior region from the right canine to the left canine. Unfortunately, after extraction of the anterior maxillary teeth, high resorption rate happens on the area. In addition, presence of the incisive canal jeopardizes the ideal position of the implants placement. As a result, enucleation of the canal content and then replaced by bone graft or substitute is necessary to improve the bone bed. Neurological impairment of the soft tissue such as paresthesia or dysesthia may exist after enucleation of the canal. In order to prevent any change in sensation and having bone augmentation at the same time, partial removal of the canal content (coronal 2/3 of its contents) and placement of allograft bone is presented in this case report. Re-entry surgery after six month of the surgical site showed an adequate bone. An implant was placed then a prosthetic restoration was placed. After one year of follow up the implant was successful and no sensory disturbances were shown. A comparison was presented before and after the treatment of the case. Clinical photos and CT figures were included.
