IG received non-surgical periodontal therapy after the screening visit, but CG did not receive treatment until the 3 months study period. Periodontal parameters were recorded at baseline and after 3 months for both groups. Rheumatoid Disease activity (RD activity) was assessed using disease activity score (DAS28), inclusive of tender joints count (TJC), swollen joints count (SJC), visual analog scale (VAS), and erythrocyte sedimentation rate (ESR) for both groups at baseline and after 3 months.Results: At the end of 3 months, IG had significant reduction in RA parameters such as tender joints count (0.0005), swollen joints count (0.0005), ESR (0.003), VAS score (0.0005), and DAS28 values (0.0005) compared to CG. Periodontal parameters at the end of 3 months were also significantly reduced in IG than in CG.Conclusion: Non-surgical periodontal therapy might have reduced the burden of systemic inflammatory markers, thus reducing severity of RA in IG. Reduction in tenderness and swelling of joints in the upper arm might have enabled the patients in IG to perform better oral hygiene maintenance procedures.","PeriodicalId":13311,"journal":{"name":"Indian Journal of Dental Research","volume":" ","pages":"154-159"},"PeriodicalIF":0.0,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142017358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The literature describes oral lesions that may arise as a result of chemotherapy. However, information regarding oral symptoms in advanced cancer patients is poor.Objective: To identify the oral manifestations like oral mucositis, dry mouth and loss of taste in patients undergoing chemotherapy treatment.Methods: We evaluated 60 patients affected by malignancy undergoing chemotherapy treatment. The clinical and pathological data such as age, gender, diagnosis of malignancy and types of treatments with anticancer chemotherapeutic drug treatment, were obtained. Patients were routinely evaluated for the presence of oral mucositis based on the Common Terminology Criteria for Adverse Events (CTCAE) v5.0 scale for adverse effects and graded. Other findings like dry mouth and loss of taste were recorded.Results: Of the 60 patients, 40 (66.6%) were male, and 20 (33.3%) females with a mean age of 53.7 years. Most patients about 63% and 83% were diagnosed with dry mouth and loss of taste, respectively and 71% of patients had mucositis. Chemotherapy drugs like Cyclophosphamide, carboplatin, nanoxel, paclitaxel, oxaliplatin, docetaxel and doxorubicin, were directly associated with oral mucositis.Conclusion: Patients treated with chemotherapy for cancer most often suffer from a multitude of intense and debilitating oral dysfunctions. Oral lesions found in patients undergoing chemotherapy were mucositis, dry mouth and loss of taste. These adverse effects and an appropriate symptomatic therapy need to be discussed with the patients. Chemotherapy has a significant but transient effect on the oral symptoms.","PeriodicalId":13311,"journal":{"name":"Indian Journal of Dental Research","volume":" ","pages":"126-130"},"PeriodicalIF":0.0,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142017359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 50 primary second molar teeth were included in the study, with 25 of them undergoing treatment with formocresol (FC) and 25 receiving treatment with NeoPutty MTA ® . The subjects were divided into two groups for treatment: the first group received a treatment involving a 1:5 dilution of Buckley's FC.

This study employs a meticulous approach to evaluate the impact of different treatments on a significant number of molar teeth, using FC and NeoPutty MTA ® as the respective treatment methods.
