Study Description

Brief Summary

Periodontitis is common in patients with cirrhosis and may lead to systemic sepsis. 1 Grønkjær et al demonstrated that severe periodontitis predicted higher mortality in patients with cirrhosis. 2 In India, the wide use of oral tobacco, smoking and poor dental hygiene fosters a dual hit to the outcomes of liver disease especially in the setting of liver transplantation. However, a causal relationship between the oral microbiome and liver disease and outcomes is a matter of conjecture. Oral bacterial diseases, such as caries and periodontitis are caused by a consortium of bacteria rather than a single species. These constitute opportunistic infections that occur under the proper circumstances and conditions, e.g., diet, host immune response, complicating systemic or genetic disorders, pH, poor oral hygiene and lifestyle. It is well known that specific bacterial taxa that colonize the oral cavity are associated with oral health and oral diseases or afflictions, such as dental caries, periodontal diseases, endodontic lesions, dry socket, halitosis, and odontogenic infections.

Bajaj et al have demonstrated systematic periodontal therapy in cirrhotic outpatients improved endotoxemia, as well as systemic and local inflammation, and modulated salivary and stool microbial dysbiosis over 30 days. Bajaj et al performed another study on comparison of oral and gut microbiota in patients with and without hepatic encephalopathy.

There were differences in salivary microbiota composition and inflammatory markers between controls and cirrhotics. The association between periodontitis, oral dysbiosis and the prognosis of cirrhosis remains crucial with relevance to situations like acute-on-chronic liver failure and other inflammation-related adverse events.

Detailed Description

The aim of this study is to prospectively determine the association of generalised Stage I & II (initial to moderate) with all-cause and cirrhosis-related mortality in patients with cirrhosis. We also plan to evaluate the oral microbiome and association of oral dysbiosis with complications of cirrhosis to assess if early treatment by dental interventions may improve nutrition and outcomes in cirrhosis. Lastly this prospective randomized controlled trial will provide insight into whether manipulation of the oral microbiome by dental procedures and oral hygiene training, antibiotics- local and systemic, use of probiotics etc can alter adverse outcomes, nutrition and health related quality of life in cirrhosis.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Periodontal therapy

Patients offered periodontal therapy in 2-4 sittings (n=40), Dental hygiene advised

Procedure: Periodontal therapy
Treatment will be performed by a periodontist. Intensive removal of subgingival and supragingival calculus and plaque biofilm by scaling, root-planing and polishing. The procedures will be carried out with the use of hand scalers and a piezoelectric ultrasonic scaler with universal tips. Disclosing solution will be used to visualize the plaque for the clinician. One to four sessions of subgingival scaling and root planing by quadrant, under local anesthesia as may be deemed necessary during the study period. Subgingival irrigation using an antiseptic mouth rinse (chlorhexidine 0.12%). Polishing of the coronal and radicular surfaces of the teeth.

Sham Comparator: Control

Patients given standard medical treatment (n=40), Dental hygiene advised

Procedure: Oral hygiene advice
Oral hygiene advised by Periodontist
