Aggregatibacter actinimycetemcomitans is an important pathogen related to aggressively progressive periodontal breakdown in adolescents and adults [4,5]. A. actinomycetemcomitans (A.a.) can be grouped into seven serotypes (a-g) [6,7]. Several studies have examined the relationship of A.a. serotype, ethnical status and geographic populations, periodontal disease status [8,9,10]. Individuals are usually colonized by a single serotype that can exist for life [8,11,12]. The frequency distribution of A.a. serotypes differs among various populations [13]. The available literature suggests that serotypes a, b. and c occur much more often among oral isolates than d, e, f and g [14,15,16]. The serotype distributions have been shown to be different among various geographic populations including African, Asian, Europeans, and North and South American [15,16,17,18,19]. The purpose of the present study was to review the studies that have investigated the prevalence and the distribution of A.a. serotypes in subgingival samples Crimson Publishers Wings to the Research Review Article","PeriodicalId":179841,"journal":{"name":"Modern Research in Dentistry","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127977084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Maxillofacial fractures mainly affect men [6-11] and have the highest incidence in the age range of 20-30 [7-9]. The maxillofacial fractures reasons are different among different population [9] and the most common causes in all over the world are traffic accidents, rape, falls, sport injuries and war [12-14].

Internal fixation with screws and plate (rigid internal fixation) has given us some tools for restoring the facial fractures with reduced morbidity more accurate [15].

Periodontal disease is the response of the immune system to the accumulation of plaque and oral microorganisms, which leads to a progressive loss of gingival tissue, periodontal ligament and alveolar bone. If it is not treated it can lead to premature loss of teeth. Parodontopathy is also associated with many systemic disorders such as diabetes, rheumatoid arthritis and cardiovascular complications, and its development is associated with a negative outcome of pregnancy. Due to all of this, periodontal disease significantly affects the patient’s quality of life and has a significant financial impact on both the patient and the public health system. The ultimate goal of periodontal therapy is to achieve periodontal regeneration with the reconstruction of all parodontium components including periodontal ligament, connective gingival tissue, cement and alveolar bone. The treatments currently in use in the world and in our country can’t completely reconstruct all of this tissues and relationships damaged by periodontal disease [1].","PeriodicalId":179841,"journal":{"name":"Modern Research in Dentistry","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127137645","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Karen, Gonçalves Sf","doi":"10.31031/MRD.2019.03.000566","DOIUrl":"https://doi.org/10.31031/MRD.2019.03.000566","url":null,"abstract":"The saliva is a fluid of extreme importance in the maintenance of oral homeostasis, being present in several biologic processes. It is composed in almost its totality by water and electrolytes, besides proteins such as immunoglobulins and mucins. This fluid acts in the lubrication of the mucosa, digestion, phonation, gustation, neutralization of acid components and in the immune systems through antimicrobial peptides against bacteria, fungi and viroses [1-5]. Hyposalivation is characterized by the decrease in the capacity of the salivary glands to secrete saliva, and xerostomia is defined as the subjective sensation of oral dryness. Such alterations can be caused by drugs, systemic diseases, head and neck radiotherapy, among other reasons [6]. Patients affected by salivary dysfunctions tend to show an atrophic oral mucosa, as well as symptoms such as dysphonia, dysphagia, oral burning sensation and palate alterations. There is increased risk to oral candidiasis, caries lesions and periodontal alterations [7-9]. The diminished bactericidal effect of saliva favors the increase of population of the microorganisms responsible for these diseases [8,10]. Head and neck radiotherapy is one of the main causes of salivary dysfunction [11,12]. The major salivary glands are usually included in the radiation portals due to the fact that they reside close to primary tumor sites and lymphatic chains of the head and neck region and frequently have their function impaired resulting in hyposalivation and xerostomia [11,13-15]. Among the radiotherapy methods most employed in head and neck region, conventional 2D radiotherapy (RC) is the one that presents the most significant side effects on the glandular tissue. Intensity-modulated radiotherapy (IMRT) and three dimensional conformal radiotherapy (3DCRT) reduce the radiation dose on the health structures close to the tumor and, consequently, the toxicity caused by the ionizing radiation [13,1620]. The salivary glands are extremely sensitive to ionizing radiation, presenting structural alterations which cause changes in salivary flow and composition [21]. These alterations are dose-dependent and can be irreversible [21,22]. Permanent hyposalivation is frequently associated to doses of ≥50 Gy, usually used for head and neck cancer treatment [23].","PeriodicalId":179841,"journal":{"name":"Modern Research in Dentistry","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117083702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite progress in treatment, the 5-year survival rate for this cancer has not improved over the past 30 years. In the hierarchical structure of stem cells present in the human oral epithelium, it is clear that stem cells are the only long-lived inhabitants of the oral epithelium and, therefore, the only cells capable of accumulating the required number of genetic changes for the development of malignancy.
