Gingivitis, Gum inflammation, Plaque, Bacteria, Periodontitis, Bleeding, Swelling

Introduction

Periodontal disease’s most obvious symptom is gingivitis. It is an illness of the teeth’s supporting tissues. Gum disease is not always a result of ageing, just as dental caries (cavities). However, any lapse in oral hygiene might make it easier for tooth caries or gingivitis to spread. As time goes on, these issues compound, and an apparent raise in their prevalence in senior people results. It is periodontal disease, not cavities, that causes the majority of tooth loss in senior people. Similar to dental caries, gingivitis is brought on by oral bacteria attacking healthy tissues. Plaque produced of these microorganisms can stick to teeth. If plaque is not removed and builds up, it can irritate the gums and lead to inflammation. Gum inflammation causes bleeding and swelling. Gingivitis is identified by these swollen and bleeding gums. If allowed to continue, it might result in the loss of the ligaments and bone that support the teeth. In turn, the teeth could become loose and disappear [1-3].

The inflammatory reaction of the gingival tissues to the pathogenic toxins and metabolic byproducts of bacteria prevalent in mouth plaque is known as gingivitis. The most typical symptom of plaque-associated gingivitis is erythematous, oedematous tissue that haloes the teeth. Patients may complain of gingival bleeding when manipulating tissue, such as during a dental check-up or regular teeth brushing. Bacterial plaque from inadequate dental hygiene is the main risk factor for gingivitis. Plaque clearance from the supra- and sub gingival layers stops the inflammatory reaction, and in most cases, gingival lesions will heal with a complete return of tissue shape and function. Periodontitis is usually preceded by gingivitis, even if periodontitis does not necessarily proceed from gingivitis.

Inflammation of the gingivae is referred to as gingivitis in general. The problem is widespread all across the world. Although many nonplaque related types of gingivitis are also known, plaque-associated instances make up the majority of cases. When oral hygiene issues cause tooth plaque and calculus to build up, gingivitis caused by plaque often follows. Additionally, a number of systemic factors, including endocrine influences (such as puberty, the menstrual cycle, pregnancy, and diabetes mellitus), medications (such as phenytoin, calcium channel blockers, cyclosporine, and oral contraceptives), hematologic disorders, and malnutrition (such as vitamin C deficiency), can alter the clinical presentation of plaque-related gingivitis. Additionally, mouth breathing, dental crowding, tooth fracture, dental prostheses or appliances, and faulty dental restorations are local variables that may lead to gingivitis. Additionally, research points to a critical role for the host response in the etiopathogenesis of gingivitis. Inflammation of the gingiva can be localised or widespread, acute or chronic. In some instances, the inflammation may only affect the gingival margin (marginal gingivitis) or the interdental papillae (papillary gingivitis), but in other instances, the gingival margin, associated gingiva, and interdental papillae may all be diffusely affected (diffuse gingivitis) [4,5].

Erythema, swelling, bleeding on light probing, blunting of the interdental papillae, swampy to firm consistency, and loss of stippling are some of the clinical signs of gingivitis. Plaque control that is professionally given, dental hygiene instruction, and the treatment of modifiable systemic or local variables are common components of management. It is advised to brush your teeth twice a day and to floss or use an interdental brush once a day to clean between your teeth. Additional chemical plaque control agents, including mouthwash flavoured with essential oils or chlorhexidine may also be helpful.

The first inflammation in the periodontal tissues should not be viewed as a disease but rather as a physiologic defence mechanism against the microbial onslaught. At this stage, the illness is characterised by the production of supragingival and sub gingival plaques, which are typically accompanied by calculus formation and gingival irritation. Plaque removal results in resolution and the restoration of equilibrium; if the lesion continues it develops into disease. For ease of usage, we’ll refer to the four well-known phases of gingivitis and periodontitis—the initial lesion, the early lesion, the established lesion, and the advanced lesion—when describing these conditions. Because it signifies the change from gingivitis to periodontitis, the advanced lesion is sometimes referred to as the destructive phase. Because immunologic events overlap at various stages of illness, it can be difficult to distinguish between inflammation and the immunologic processes that underlie periodontal disorders. It is important to note that immunologists imposed a very artificial difference when they divided the immune response into several categories, such as innate immunity and adaptive immunity. Even though it is simpler to define inflammation in compartments, all immune system elements that work together to preserve the periodontium are engaged in the mechanisms of inflammation, resolution, and healing. It’s crucial to keep in mind that the previous routes continue to work as the lesion gets worse [6-8].

Plaque-induced inflammation that is limited to the surface-level gingival tissues is referred to as chronic gingivitis. Gingival bleeding after slight trauma (usually during tooth brushing or dental probing, but occasionally even during mastication), redness of the marginal gingivae, and gingival swelling are all clinical indicators of gingivitis. It is often painless, and although while noticeable gingival redness and swelling can occasionally be detected, the changes caused by the disorder are frequently mild and go unnoticed by the person who has it. Clinical examination may reveal loss of the connected gingivae’s stippling, loss of the distinct “knife edge” look of the interdental papillae, and loss of the mucogingival junction between the (keratinized) gingival epithelium and the (non-keratinized) alveolar mucosa. Gingivitis frequently resolves on its own and can last for many years without worsening. Following the introduction of sufficient plaque control methods and the elimination of elements like calculus and uneven restoration margins that encourage dental plaque collection, it is completely reversible. According to epidemiological research, gingivitis may affect the majority of people and is thought to be the body’s natural reaction to plaque build-up on the tooth surface next to the gingival border.

The physiological reaction to a number of wounds or traumas, such as heat, chemicals, or bacterial infection, is inflammation. The reaction occurs quickly and lasts very briefly during the acute phase of inflammation. The reaction can be categorised as non-physiologic or pathologic if it persists after the insult or damage if it is not healed. The cellular and non-cellular processes of acquired immunity are involved when inflammation develops into a chronic condition, activating the adaptive immune response. Additional functions of immune systems include tissue repair and regeneration for missing or injured tissues, as well as the control of inflammation and the healing process. In order to bring the damaged tissue back to equilibrium, innate (inflammatory) immunity and acquired immunity must be synchronised. Bacteria are the cause of periodontal disorders. The number of microbial species found in the human mouth cavity is significant and constantly changing. The ecological interactions of the host and the bacteria control how serious the illness is. Periodontal disorders, in contrast to many infectious illnesses, seem to be infections caused by an overgrowth of commensal microorganisms rather than by the acquisition of an external pathogen. Immune systems that control the ecological balance of commensal organisms must adapt to maintain equilibrium when bacteria grow more quickly than their mammalian hosts [9, 10].

Conclusion

Periodontal disorders are inflammatory illnesses in which a number of host responses brought on by microbial etiologic factors cause inflammatory processes. Dysregulation of immunological and inflammatory pathways causes illness, chronic inflammation, and tissue damage in those who are susceptible. A well organised network of cells, mediators, and tissues makes up physiological inflammation. Instead of numerous diverse modules operating independently, it is crucial to take into account the inflammatory and immunological response as a whole. It is crucial to have a deeper knowledge of the molecular and cellular activities in this complex system since illness appears to be caused by a loss of control and a failure to return to homeostasis. The paradigm shift in how we think about inflammatory diseases, including periodontitis, is that the process of reducing inflammation is no longer passive but rather involves the activation of particular biochemical programmes. Arachidonic acid, a dietary supply, and omega-3 fatty acids, a precursor fatty-acid substrate, both produce lipid mediators (lipoxins and resolving, respectively) that counteract proinflammatory signals. It is becoming more and more clear that the treatment of periodontal infections and patients undergoing periodontal surgery in the future will depend on practitioners having a thorough understanding of the resolution programmes for inflammation and tissue damage at the molecular level.

Treatment of bacterially induced illness requires a thorough temporal analysis of infection and resolution in human tissues. Studies on disease models imply that increased inflammation and a breakdown of innate mucosal antibacterial mechanisms are to blame for the infection is becoming chronic and the pathogen persisting. Therefore, uncontrolled resolution of the inflammatory process may contribute to susceptibility to chronic inflammatory illnesses. Research into the coordination of this complex system may help us get closer to improved treatment choices, which are now restricted and only partially effective for treating periodontitis. Some medications, like as selective cyclooxygenase 2 inhibitors and specific lipoxygenase inhibitors, have shown to be toxic to the resolution programmes. This is because many modern and commonly used medications have been created without consideration for their effect in resolution circuits. It will be critical to ascertain whether resolution pharmacology produces fresh medications for illnesses affecting people.
