Introduction Lichen Planus has been classified as both a cell-mediated immune response as well as an autoimmune condition. A target antigen in the reaction has not been identified. The mechanism of action and exact classification of the condition is not fully understood. Histologically, evidence of T-cell destruction of basal cells is observed. Tumor Necrosis Factor-Alpha (TNF-a) is thought to have major involvement in this reaction. Lichenoid reactions resemble Lichen Planus both clinically and histologically but differs due to evidence of local irritant or use of certain systemic medications. Local factors could be dental materials which could include but not be limited to gold crown, PFM crown, amalgam restorations and oral hygiene products [1]. Management of oral lichen planus and lichenoid reactions poses a challenge due to lack of full understanding of the etiology. Additionally, the multifactorial probable causes of these reactions contribute to the complexity of management [2]....

Abstract Background:  Chronic gingivitis is a common disease, especially among adult patients who often develop periodontal pocket and the occurrence gradual loss of the periodontal attachment. A wide range of microorganisms is known to be associated with periodontal disease, including Porphyromonas gingivalis (Pg) and Aggregatibacter actinomycetemcomitans (Aa). Objectives:  Therefore, a study was conducted to determine the effect of phototoxicity of visible blue light (vBL) on Aa and Pg Clinical isolates from chronic periodentitis patients, and to study their antibiotic sensitivity against selected antibiotics. Methods: The test was carried out on 15 strains of Aa and 15 strains of Pg isolated from pockets of chronic periodentitis patients aged between 30-50 years old with pocket depths of 5-6mm. Bacteria cultured, isolated, identified by standard bacteriological methods, and then exposed to visible blue light for different periods of time. After bacterial cultures were expos...

Abstract We present a case of a Panton-Valentine Leukocidin (PVL) positive Staphylococcus aureus (SA) infection in an otherwise fit and well 21 year old man. This bacterial infection was preceded by a reactivation of a cold sore on his lower lip. The formation of an abscess and localised tissue necrosis prompted the search for this unusual and dangerous toxin.

Abstract In recent days teeth hygiene is a social image and physiological strength to the people. People spend the huge amount for the oral hygiene with respect to daily use toothbrush, toothpaste, mouth rinses, etc. Everyone desires to maintain a brighter and whiter tooth with smile, no one interested in the yellowing coloring teeth. Many people use the cosmetic dentistry to maintain the teeth as a brighter white in color and shine. Many teeth whitening gel, paste, rinse off products recommended by the dentist and available in over the counter product. In general hydrogen peroxide, carbamide peroxide and peroxide releasing substances used as a bleaching agent. The present study aimed to estimate the clinical efficacy of Whitening toothpaste containing the Salt and Lemon with respect to the substantiation of product claims like whitening thorough cleansing, intense freshness and removal of yellow stains. At the end of study period almost 76% of people moved or shifted to the ‘Good’ sca...

Abstract In partially or totally edentulous patient, the jaws can have severe limitation for conventional implant treatment. Resorption of jaw reduce in many cases the amount of bone available both in thickness and height, and in the lower jawbone quality is less dense, more bone narrow and thinner than the forehead. The purpose of this work is to present an alternative technique to normal sinus lift in the upper jaw and bone graft in the mandible with minimal invasive approach to reduce biological costs, without bone regeneration with immediate loading, immediate aesthetic and immediate function.

Abstract Background and objective:  Porphyromonas gingivalis (Pg), is an important periodontal pathogen known to possess various virulence factors such as the extracellular gingipain proteases. These play a role in destruction of periodontal tissue. Naturally occurring polyphenols were shown to play a role in preventing bacterial pathogenicity by neutralizing proteolytic enzymes. We sought to examine the role of a prenylated flavonoid, Sanggenol A, on neutralization of Pg gingipain proteolytic activity Materials and methods:  The effect of Sanggenol A on the secreted and cell-associated gingipain activity of Pg was measured using fluorogenic substrates, and the resulting fluorescence was measured by fluorescence reader. Results:  The results revealed an inverse correlation between the concentration of Sanggenol A and both secreted and Pg cell-associated gingipain activity. The activity of R gingipain (Rgp) was found to be significantly more susceptible to Sanggenol A inhi...

Abstract An experimental theoretical substantiation and hardware and software application of Raman-fluorescent medical technologies in dentistry are presented. Highly sensitive and highly specific express methods for diagnosing caries, the degree of demineralization of hard tooth tissues, specific indication of microbes and rapid determination of their sensitivity to drugs, verification of drugs and narcotic substances, express diagnosis of benign and malignant tumors are proposed. A wide range of clinical and diagnostic capabilities of the method and the proposed domestic hardwaresoftware complex of Raman-fluorescent diagnostics is recommended for clinical use.

Abstract There is a need for updating the current treatment modalities for periapical lesions of endodontic origin to reflect the contributions and potential morbidity from herpesvirus infection. Herpesviruses, particularly human cytomegalovirus and Epstein-Barr virus, play an important role in the symptomatic periapical lesion. Indeed, periapical lesions may remain stable and silent until they become symptomatic, possibly triggered by the activation of latent herpesviruses within the lesion itself. Given the potential for grave systemic conditions associated with herpesvirus infection, early detection and treatment decisions for periapical lesions by the dentist may positively affect a patient’s overall health; especially for the immunocompromised patient.

Introduction Whitening oral rinses and dentifrices are classified as over the counter (OTC) Tooth whitening products. Color relapse of bleached teeth is a significant issue with different reported results. Coffee, tea, wine, nicotine, and cola-based soft drinks might be considered as contributing factors that cause color regression of bleached teeth. To maintain the whitening effect for a longer time, whitening toothpaste and mouth rinses can be relatively used as an additional agent. These products can be used alone or in conjunction with inoffice or home bleaching procedures.

Short Communication Orthotropics is a wellness strategy that enables children to develop straight teeth and good dental and jaw alignment. However, equally important, the orthotropic approach also improves facial appearance and positively impacts a child’s health through airway development and better posture. Ideally active orthotropic treatment begins between the ages 6-8 and finishes long before most traditional orthodontic treatment would even begin. It addresses the underlying causes of bad bites and misaligned teeth utilizing removable dental appliances as opposed to braces. If begun at the ideal age, Orthotropics negates the need for the extraction of adult teeth or jaw surgery and minimizes or eliminates the need for fixed braces during adolescence [1].

A Case Report Pathological tooth migration is difficult to treat; the improvement of the periodontal condition is necessary to stop the disease; fixed appliance gives extra obstacles for oral hygiene practices. Clear aligners make no difference in brushing and flossing during the treatment but have more limitations in tooth movements especially extrusion and derotation. Careful design and flexible treatment strategies for clear aligners are crucial to treat rotated tooth complicated by pathological migrated tooth. This case report showed clear aligners could be used for derotation and extrusion.

Abstract Background and objectives:  Recurrent Aphthous Stomatitis (RAS) is one of the most common oral mucosal diseases. This study aimed to determine the prevalence of RAS, the association of Immunoglobulin E with RAS and potential risk factors of RAS in patients at dental clinics of Sana’a universities in Sana’a city, Yemen. Subjects and methods:  A cross-sectional study was conducted from January to December 2017 and includes 2164 patients. The patients interviewed and examined by dentists and 72 were clinically diagnosed to have RAS. The patients with RAS responded to a questionnaire that included demographic background, Qat chewing habits, smoking habits, history and course of RAS episodes. They were also subjected to laboratory tests, including determination of serum IgE levels and xerostomia. Results:  The crude prevalence of RAS was 3.3%; female prevalence was 3.8% slightly higher than 2.4% of the male. There was a higher rate of RAS in age group 16-25 years (12....

Abstract Health is a required element for a balanced human existence. The patients’ inability to pay for medical services limits their access to medical care and aggravates a disease which could be cured earlier with fewer resources. Beyond the impact of dental pathology on the individual through pain and discomfort, with subsequent consequences on general health and quality of life, negative effects are reflected on the entire community, affecting the healthcare system well as the economic system.
