Comparative evaluation of the efficacy of a novel tetracycline-coated suture with triclosan-coated and noncoated sutures on bacterial load reduction: A prospective in vitro study.

Background: Surgical site infection (SSI) is one of the common postoperative complications observed after various periodontal surgeries, and sutures play a vital role in its causation. Thus, the aim of this study is to evaluate and compare the efficacy of a novel tetracycline-coated suture with triclosan-coated and nonantibacterial-coated sutures on bacterial load reduction to prevent SSI by measuring the zone of inhibition. Materials and Methods: Twenty systemically healthy individuals with moderate chronic periodontitis were included in this study. Fresh unstimulated saliva was collected from each patient and inoculated on three different blood agar plates. Sutures were divided into three groups (Group A: Tetracycline-coated suture, Group B: Triclosan-coated suture, Group C [control group]: Nonantibacterial-coated suture). The antibacterial efficacy of each suture was evaluated by performing agar diffusion test. The zone of inhibition around each suture was calculated, and statistical analysis was performed for the same using Kruskall-Wallis ANOVA test and Mann-Whitney U-test. Results: On intergroup comparison, there was a statistically highly significant difference seen for the zone of inhibition between the groups (P < 0.01) with the highest values in Group A (14.45 mm), followed by Group B (1.4 mm) and least in Group C (0 mm). Conclusion: Tetracycline-coated suture is more efficacious than triclosan-coated suture to reduce bacterial load and further prevent SSIs. However, in vivo clinical trial is must to prove the same.

A curious case of gingival enlargement - From seropositive diagnosis for human immunodeficiency virus to periodontal management.

Gingival enlargement may be a result of multifactorial etiology which includes local factors such as calculus, food lodgement, overhanging restorations, and overextended dentures as well as systemic conditions such as hormonal disturbances and blood dyscrasias. Acquired immune deficiency is a manifestation of immune disorder caused by a retrovirus Human Immunodeficiency Virus (HIV). The association of Acquired Immunodeficiency Syndrome or HIV with oral and periodontal lesions is highly significant. Seropositive patients usually present with periodontal diseases and atypical periodontal lesions. These clinical findings may prove to be a link for probing patients' systemic health. This case report describes one such case of a patient, unaware of HIV infection with localized gingival overgrowth, wherein detailed probing and investigation led to the diagnosis of underlying systemic condition as acquired immunodeficiency. Subsequently, antiretroviral therapy was started, and nonsurgical periodontal therapy was performed to resolve the gingival overgrowth.

Leiomyoma on gingiva with osseous involvement: An unusual presentation.

Leiomyoma is a smooth muscle tumor which rarely turns into malignancy. This is an unusual case report which presents leiomyoma on gingiva with osseous involvement. This case highlights the importance of histopathological examination for the proper diagnosis of any gingival growth. A 28-year-old female patient reported with localized gingival enlargement. The surgical excision was conducted and excised tissue was sent for histopathological examination. On the basis of clinical and histopathological examination, the diagnosis of leiomyoma was made. Leiomyoma reported low recurrence rate in previous literature. However, this lesion recurred within 15 days. After recurrence, the patient was referred to the oncology center for further evaluation and treatment.

Evaluation of accuracy of cone beam computed tomography for measurement of periodontal defects: A clinical study.

AIMS: The aim of the present study was to evaluate the accuracy of Cone Beam Computed Tomography (CBCT) measurements of alveolar bone defects caused due to periodontal disease, by comparing it with actual surgical measurements which is the gold standard. MATERIALS AND METHODS: Hundred periodontal bone defects in fifteen patients suffering from periodontitis and scheduled for flap surgery were included in the study. On the day of surgery prior to anesthesia, CBCT of the quadrant to be operated was taken. After reflection of the flap, clinical measurements of periodontal defect were made using a reamer and digital vernier caliper. The measurements taken during surgery were then compared to the measurements done with CBCT and subjected to statistical analysis using the Pearson's correlation test. RESULTS: Overall there was a very high correlation of 0.988 between the surgical and CBCT measurements. In case of type of defects the correlation was higher in horizontal defects as compared to vertical defects. CONCLUSIONS: CBCT is highly accurate in measurement of periodontal defects and proves to be a very useful tool in periodontal diagnosis and treatment assessment.
