Biomaterials are widely used in guided bone regeneration (GBR) and guided tissue regeneration (GTR). After application, there is an interaction between the host immune system and the implanted biomaterial, leading to a biomaterial-specific cellular reaction. The present review focuses on cellular reactions to numerous biomaterials in vivo with consideration of different implantation models and microenvironments in different species, such as subcutaneous implantation in mice and rats, a muscle model in goats and a femur model in rabbits...

Odontogenic tumours are a group of heterogeneous diseases that range from hamartomatous or non-neoplastic tissue proliferations to benign neoplasms to malignant tumours with metastatic potential. They are rare, comprising about <2-3% of all oral and maxillofacial biopsy specimens. The aim of the present study was to determine the clinico-pathological presentation of this heterogeneous group of lesions and review of literature. The present study was conducted in the ENT department of a Government Medical College and Hospital, West Bengal, India, over the period of 5 years from January 2011 to December 2015...

BACKGROUND: Despite continuous advances in diagnosis and therapy, oral cancers are mostly diagnosed at advanced stages with minor survival improvements in the last two decades. Both phenomena have been attributed to delays in the diagnosis. This study aims at quantifying the time elapsed until definitive diagnosis in these patients and the patient interval's contribution. MATERIAL AND METHODS: A hospital-based, ambispective, observational study was undertaken on incident cases with a pathological diagnosis of oral squamous cell carcinoma recruited during 2015 at the Oral and Maxillofacial Surgery services of CHUAC (A Coruña) and POVISA (Vigo) hospitals...

Maxillofacial images must be examined to find pathologies not identified during clinical examination. Unicystic ameloblastoma (UA) extending to the mandibular body and ramus was neglected on initial panoramic radiographic examination. After orthodontic therapy, a huge lesion was observed clinically and through imaging exams. After the conservative surgery, no recurrence was observed during five years of follow-up. This case emphasized the need for careful evaluation of patient images focusing on the oral diagnosis before any dental treatment planning, including orthodontic therapy...

This Point/Counterpoint acknowledges the transformation of dental practice from a predominantly technically based profession with primary emphasis on restoration of the tooth and its supporting structures to that of a more medically based specialty focusing on the oral and maxillofacial complex. While both viewpoints accept the importance of this transformation, they differ on the ultimate desired outcome and how changes should be implemented during training of dentists as oral health professionals. Viewpoint 1 argues that, in response to a shortage of both primary care providers and access to affordable oral health care, dentists need to be able and willing to provide limited preventive primary care (LPPC), and dental educators should develop and implement training models to prepare them...

REVIEW
Karl M Lyons, Ivan Darby
Periodontics cannot be practiced in isolation as frequently many patients have multiple dental needs or medical health issues requiring management. In addition, pathology may manifest in the periodontal tissues, and the onset and progression of periodontitis can be affected by systemic conditions, such as diabetes, and vice versa. The focus of this volume of Periodontology 2000 is interdisciplinary periodontics, and the articles included discuss the interactions and the interrelationshipbetween periodontal tissues/periodontal diseases and endodontics, fixed prosthodontics, implant dentistry, esthetics, gerodontology, radiology, orthodontics, pediatric dentistry, oral and maxillofacial surgery, oral pathology, special needs dentistry and general medicine...
