ABSTRACT
Background: Porphyromonas gingivalis is a major periodontal pathogen. Saliva is the most easy, non-invasive microbiological sample for detection of periodontal pathogens. Aim and Objectives: A prospective study on 37 diabetic patients was grouped into well-controlled diabetes with/without periodontitis and uncontrolled diabetic with periodontitis. PCR and sequencing of P. gingivalis was performed in saliva samples. Materials and Methods: DNA was extracted from saliva using Triton X-100 and 16s rRNA gene (404 bp) was amplified by polymerase chain reaction. DNA sequencing was performed for two samples. Results:P. gingivalis was detected in 27.03% (n = 10), of which 30% (n = 9) were diabetic with periodontal disease and 14.3% (n = 1) were diabetic without periodontal disease. The percentage of poor oral hygiene was 50% and 20% in uncontrolled and controlled glycaemic patients, respectively. DNA sequencing of two samples showed 100% identity with the sequences in the GenBank database (Gen Bank accession no: KX640913-KX640914). Conclusion: Type 2 diabetes mellitus and periodontitis are interlinked. Early detection of P. gingivalis and appropriate treatment with doxycycline will also assist in controlling the glycaemic status.
ABSTRACT
This paper aimed to report a rare case of fusion of 6th and 7th cervical vertebrae, called as block vertebrae. Block vertebrae was observed in the Department of Anatomy, SRM Dental College. The bodies of C6 and C7 were completely fused. Anterioposterior radiograph of the fused vertebrae bodies showed hypoplastic inter vertebral disc. Lateral radiograph showed partial fusion of articular processes on left but remain unfused at the right side. Congenital cervical vertebral fusion results due to non-segmentation of sclerotomes. It may be asymptomatic or may result in various clinical symptoms with limitation of neck movements. Knowledge about the variations in vertebrae especially in cervical region is essential for orthopedic surgeons, oral-maxillofacial surgeons and physical therapists for planning any surgeries involving the neck region.
