Single versus two dental implants retained mandibular over dentures: comparison of function, patient satisfaction, oral health-related quality of life and success of treatment.

Objective: To compare the effectiveness of prosthetic rehabilitation of edentulous patients using conventional complete dentures (CD), single median dental implant retained over dentures (SIMOD) with over dentures retained by two dental implants (TIMOD).

Methods: Thirty completely edentulous patients (fifteen each arm) presented to the Faculty of Dental Sciences, University of Peradeniya were randomly selected for the SIMOD or TIMOD groups. Patients were initially provided with CD.

Malignancy and "Violated Neck" Rates in Consecutive Cohort of 79 Adult Patients With Solitary Cystic Neck Mass-Lessons Learned and Recommendations for Clinical Practice Guidelines.

Objective: The neck region is a common site for solitary cystic neck mass (SCNM) of various etiologies, including congenital, inflammatory, and neoplastic. In adults, the primary focus is excluding malignancy. The objective of this study was to retrospectively analyze the accuracy of available diagnostic technologies for the differentiation of benign and malignant SCNM in adult patients.

Perceived Satisfaction of Patients and Related Factors for Oral Surgery Student Dental Clinic: Evidence From Sri Lanka.

We assessed perceived satisfaction of patients and related factors for treatment provided by the oral surgery student dental clinic of the only Sri Lankan dental school. A descriptive cross-sectional study was conducted among 288 consenting patients who received oral surgery treatment at the student dental clinic of Department of Oral and Maxillofacial Surgery, Faculty of Dental Sciences, University of Peradeniya, Sri Lanka. A self-administered, validated questionnaire and a 19-item multidimensional patient satisfaction scale were used for data collection.

Economic cost of managing patients with oral potentially malignant disorders in Sri Lanka.

Objectives: Cancer of the oral cavity is the leading malignancy amongst males in Sri Lanka, and eighth amongst women. Almost all malignancies are developed from a clinically visible precursor stage called an oral potentially malignant disorder (OPMD). The objective of this study was to estimate costs of managing patients with OPMD in Sri Lanka for a 12-month period from diagnosis.

Low-Grade Myofibroblastic Sarcoma of the Oral Cavity: A Report of Three Cases Illustrating an Emerging Disease in Children.

Low-grade myofibroblastic sarcoma (LGMS) is a mesenchymal tumor of myofibroblasts that occurs more frequently in adults. A series of three cases is presented to illustrate that LGMS may also occur within the oral cavity in children and adolescents. The first case (Case 1) occurred intra-osseously in the mandible, while the remaining two presented as gingival swellings and were purely restricted to soft tissue (cases 2 and 3).

Economic burden of managing oral cancer patients in Sri Lanka: a cross-sectional hospital -based costing study.

Objective: Cancer of the oral cavity is the leading malignancy among males in Sri Lanka, and sixth among women. This study aimed to estimate costs of managing patients with oral cancer (OCA) in Sri Lanka for a 12 month period from diagnosis.

Design: Hospital based costing study.

Effects of epidermal growth factor on the invasion activity of the oral cancer cell lines HSC3 and SAS.

Epidermal growth factor (EGF) is excreted in a high concentration in human saliva and modulates the growth and differentiation of various cancer cells. To elucidate the molecular mechanisms by which EGF affects oral cancer growth and invasion, we analyzed the Matrigel invasion activity of the cultured oral cancer cell line. Cells grown under the influence of EGF were subjected to Matrigel invasion assays and cells grown in the absence of EGF were used as controls.
