Background: Periodontology is a fast-evolving field with newer insights into traditional periodontal diagnosis. Advances in periodontal disease diagnostic research are moving toward methods whereby periodontal risk can be identified and quantified by objective measures such as biomarkers. Objectives: The aim of this study was to evaluate malondialdehyde (MDA) levels in whole saliva of patients with chronic periodontitis. Materials and Methods: Whole saliva samples were collected from 85 patients: 30 patients with chronic periodontitis, 25 with gingivitis, and 30 periodontally healthy controls. To determine the clinical condition of each subject, the gingival index and clinical attachment level were measured. The salivary MDA levels were determined spectrophotometrically. Results: Higher salivary MDA levels ( P < 0.005) were detected in patients with periodontitis compared to the healthy controls. There was no statistically significant difference in the salivary MDA levels between patients with gingivitis and healthy controls. Conclusions: Higher salivary MDA levels seem to reflect increased oxygen radical activity during periodontal inflammation. Thus, MDA can be used as a marker of oxidative stress in patients with periodontitis.

Platelet concentrates (PCs; platelet-rich plasma and platelet-rich fibrin) are autologous bioactive substances that have found varied application in medical and dental fields, particularly in oral and maxillofacial surgery, plastic surgery, and sports medicine. The rationale of these technologies is to extract all the elements from patient’s own blood sample, which could be used to improve healing by promoting tissue regeneration. PCs have evolved a long way since its introduction in 1954. PCs have been used successfully in periodontics and implant dentistry. However, the preparation protocol, processing time, transfer of concentrates, centrifugation temperature, vibration, etc., being not standardized are various factors for the mixed results reported in the literature. This review intends to discuss evolution of PCs, their preparation techniques, and their clinical and technical aspects and applications.

Aim:The study aims to assess the Mentha piperita leaf extract's effectiveness against oral pathogens. Materials and methods:The leaf extract of M. piperita was prepared using cold water method. The three microbial strains, i.e., Streptococcus mutans, Aggregatibacter actinomycetemcomitans, and Candida albicans were used as microbiological materials. Chlorhexidine 0.2% was used as positive control. The digital caliper was used to measure the zone of inhibition to know the antimicrobial activity at 24 and 48 hours. To compare the activity within and between the different microbial strains, one-way analysis of variance (ANOVA) was used. To analyze the data, Statistical Package for the Social Sciences (SPSS) software version of 21.0 was used. The p-value <0.05 was considered as statistically significant.Results: Maximum inhibition zone was seen in both M. piperita extracts and 0.2% chlorhexidine with S. mutans at 24 and 48 hours, followed by A. actinomycetemcomitans, and C. albicans respectively. The statistical analysis ANOVA reveals the statistically significant association of M. piperita extracts with p-value <0.001. The comparison with 0.2% chlorhexidine at 24 hours showed a p-value of <0.04 and at 48 hours, it showed a p-value <0.001, which was statistically significant. Conclusion:The present study concluded that M. piperita showed antimicrobial activity against the oral microorganisms which are causing major less or more severe oral diseases

Injuries to oral soft tissue can be accidental, iatrogenic, and factitious trauma. Chemical, thermal, and physical agents are the main causative agents for oral soft-tissue burns. The present case describes the chemical burn of oral mucosa caused by tetracycline hydrochloride and its management. Diagnosis was made on the basis of definitive history elicited from the patient. The early detection of the lesion by the patient and immediate institution of therapeutic measures ensure a rapid cure and possible prevention of further mucogingival damage. In addition, we believe that proper guidance and education of the patient is an important prophylactic measure in preventing this self-inflicting injury.

Polycythemia vera is a rare case confronted in dentistry with scarcely available case reports. Hence a scrupulous knowledge of it is inevitable. It is a myeloproliferative disorder characterized by excessive proliferation of erythroid elements, granulocytic and megakaryocytic cells. Here, the blood viscosity increases leading to menace of thrombosis. The medications often used include cytoreductive agents like hydroxyurea 500mg to reduce the leukemogenic risk and Ecospirin 75mg to lessen the thrombotic risk in artery. A 44-year-old male patient reported with a history of pain over the upper right back tooth region since two weeks. The pain was sudden in onset sharp intermittent non radiating aggravates on taking cold fluids and relieves by itself. He also complained of food lodgement around the same site. He is a known case of absolute polycythemia in the last 8 months, undergoing treatment with Ecospirin 75mg and frequently subjected to phlebotomy. A synchronized endeavour by hemato-oncologist and dentist is required for dental treatments, peculiarly invasive therapies, in such patients. Further, an awareness of the medication used for the treatment is unavoidable.
