Effect of Gutka Chewing on Periodontal and Peri-implant Health

Gutka, a smokeless tobacco product composed of areca nut, tobacco, slaked lime, and other additives, poses a significant threat to oral health, particularly periodontal tissues. The chemical constituents of gutka, including nicotine and arecoline, induce a cascade of inflammatory and degenerative changes in the periodontium. Nicotine promotes vasoconstriction, impairing blood flow and reducing the delivery of nutrients and oxygen to gingival tissues, which compromises healing. Arecoline stimulates fibroblast proliferation and collagen crosslinking, leading to fibrotic changes and impaired tissue turnover. These factors contribute to gingival recession, increased periodontal pocket depths, and alveolar bone resorption. Furthermore, gutka alters the oral microbiome, promoting a dysbiotic environment that favours the growth of periodontal pathogens such as Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans. The proinflammatory cytokines released in response, such as interleukin-1 beta and tumour necrosis factor-alpha, exacerbate connective tissue breakdown and osteoclastic activity, leading to progressive periodontal destruction. It is reasonable to hypothesize that gutka chewing may adversely affect the stability of dental implants by inducing a state of oxidative stress in peri-implant tissues and augmenting the accumulation of osteoclasts, pathogenic bacteria, and pro-inflammatory cytokines thereby increasing risks of peri-implant diseases (peri-implant mucositis and peri-implantitis). However, there is a dearth of studies that have assessed the impact of gutka on specifically peri-implant health.
