c Abstract: Erythema multiforme is considered as an immunologic disease possibly occurring because of predisposition to certain microorganisms, radiotherapy, systemic diseases, malignancy, and food or drug allergy. Here we report a case of herpes-induced recurrent erythema multiforme primarily manifesting in oral mucosa during first two episodes and third episode was characterized by oral lesio...

Sir, Periodontitis is a destructive inflammatory disease of the supporting tissues of the teeth and is caused either by specifi c microorganisms or by a group of specific microorganisms , resulting in progressive destruction of periodontal ligament and alveolar bone with periodontal pocket formation, gingival recession, or both.[1] Periodontitis has been proposed as having an etiological or mod...

Microorganisms play an unequivocal role in infecting root canal system. Endodontic infections are different from the other oral infections in the fact that they occur in an environment which is closed to begin with since the root canal system is an enclosed one, surrounded by hard tissues all around [1,2]. Most of the diseases of dental pulp and periradicular tissues are associated with microor...

Recent studies have shown that although the different designs applied to the filament arrangement of the bristles of the toothbrushes show an improvement in plaque removal, it may also increase bacterial retention and growth. In fact, this event may create more damage instead of benefit in our regular oral hygiene because it may become a possible source for oral recontamination. The new designs...

Microorganisms from the oral flora were examined for the production of bacteriolytic substances. Among human viridans group streptococci, only one group of strains with thiol-dependent properties was shown to secrete enzymes with bacteriolytic activity on heat-killed cells of Micrococcus luteus on double-layer nutrient agar plates. By morphology, culture requirements, and biochemical properties...

Oral microbes play a critical role in maintaining oral homeostasis. Microbial dysbiosis promotes disease pathogenesis through several mechanisms. Recent studies have revealed that microbial imbalance and sustained inflammation are involved progression. The adverse interaction triggered by host immune response to microorganisms can lead systemic diseases. Here, we reviewed how communicate with h...

BACKGROUND Streptococcus mutans, Candida albicans, and Enterococcus faecalis are the three oral microorganisms most commonly implicated in the causation of oral infections. All these oral microorganisms have shown resistant to routinely used antimicrobials. There is a need for an antimicrobial agent which is effective, safe, and economical. Zingiber officinale, commonly known as ginger is one s...

We evaluated the effects of special oral care using a toothbrush with combined irrigation and suctioning functions, along with povidone-iodine to treat oral bacteria and mucositis, in esophageal cancer patients undergoing chemoradiotherapy. In the special care group, oral hygiene was performed 3 days a week after dinner. Bacteria in saliva and plague samples were measured at various sampling po...

The health of the oral cavity is threatened by a variety of microorganisms. Impaired immune surveillance of the oral environment contributes to the development of infectious processes and tumors of the mouth. Elucidation of the physiological mechanisms that determine and control oral immune surveillance is crucial to an understanding of these oral diseases. The ability of lymphocytes to migrate...
