Least Expensive Facial Mask Against Corona Virus for Short Airway Procedures Generating Aerosol.

With ongoing Corona-pandemic, the quality of personal protection equipment (PPE) across the globe is creating controversy. This article presents a novel design of a facial mask that seems suitable to deal with short airway procedures protecting the surgeon from aerosol infection. The concept, design advantages and limitations are discussed. In absence of good quality PPEs this is an excellent option to deal with airway emergencies.

Perio-ortho interdisciplinary approach in a 50-year-old patient: A case report with 5-year follow-up.

Esthetic demands for correction of irregularities of dentition are becoming a prime concern even in patients above the age of 40 years. Severe periodontitis, being insidious, if present simultaneously, complicates the situation. Periodontally compromised adult patients requiring the treatment for malaligned teeth are encountered very frequently in daily practice, and the correction of these requires a combined perio-ortho interdisciplinary approach. The present case report deals with a 5-year follow-up of a case whose prime concern was rotated anterior teeth in the maxillary arch. However, along with this, severe periodontitis was also present. Open flap debridement along with osseous grafting was done wherever required, followed by fixed adjunctive orthodontic treatment. After the completion of orthodontic treatment, a fixed retainer in the form of splinting was given and the entire treatment met the esthetic along with functional demands of the patient. Early 6 months followed by yearly follow-ups reflected clinical and radiographic improvements in the dentition.

Clinical efficacy of subgingivally delivered simvastatin gel in chronic periodontitis patients.

BACKGROUND: Simvastatin (SMV), a new locally delivered drug of class statins, is a specific competitive inhibitor of 3-hydroxy-2-methyl-glutaryl coenzyme A reductase. Statins, besides having lipid-lowering abilities, also have pleiotropic effects like host modulation and bone regeneration. The present study was designed to investigate the effectiveness of SMV, 1.2 mg, in an indigenously prepared biodegradable controlled-release gel as an adjunct to scaling and root planing (SRP). MATERIALS AND METHODS: A total of 60 sites, with pocket depth ≥5 mm, two from each of 30 patients after SRP, were categorized into two treatment groups, for subgingival placement of placebo (Gp 1) or SMV (Gp 2). Clinical parameters were recorded at baseline and at 1, 3 and 6 months comprising plaque index, gingival index, probing pocket depth (PPD) and clinical attachment level (CAL). The osseous changes were evaluated radiographically by measuring vertical gain, INFRA 1 and angle of the defect, INFRA 2 from baseline to 6 months. RESULTS: All subjects tolerated the drug, without any post-application complication. The treatment improved the periodontal condition in both the groups but significant reductions in PPD (p= 0.04), and INFRA 1 (p= 0.000), along with gain in CAL (p= 0.02) and INFRA 2 (p= 0.000) were observed in Gp 2. In one site, an unexpected 5 mm decrease in INFRA 1 was found. CONCLUSION: Local drug delivery of SMV enhanced the beneficial effect of SRP, in pocket reduction, gain in CAL and bone fill.

The detection of BANA micro-organisms in adult periodontitis before and after scaling and root planing by BANA-Enzymatic™ test kit: An in vivo study.

BACKGROUND: Many paraclinical methods are available today for an accurate assessment of the periodontal status prior and during the periodontal treatment. The microbial-enzymatic N-benzoyl-DL-arginine-2-napthylamide (BANA) test is one of the modern alternatives to bacterial cultures. It detects the presence of three periodontal pathogens in the subgingival plaque (Porphyromonas gingivalis, Treponema denticola and Tannerella forsythia). AIMS AND OBJECTIVE: The aim and objective of this study was to detect the presence of BANA micro-organisms and also to determine the effect of scaling and root planning in adult periodontitis patients. MATERIALS AND METHODS: A total number of 20 patients (80 sites) all having periodontitis were selected. Four test sites (permanent molar from each quadrant) were selected from each patient and assessed for plaque index, bleeding index and pocket depth before and after scaling and root planning. BANA test was used for the detection and prevalence of the "red complex" bacteria in plaque samples. RESULTS: Showed that the BANA tests are statistically correlated with the severity of periodontal destruction. There was a significant correlation between the BANA test results and the quantity of bacterial plaque, the test being influenced by the composition of bacterial plaque. CONCLUSION: This study encourages the use of such chair-side tests for a proper diagnosis of periodontal disease and for a good evaluation of the treatment results.

Root amputation and perio-esthetics in salvaging a premolar.

A 32-year-old patient with complete denudation of buccal root of tooth no. 14 was referred from the Department of Oral Surgery for opinion, as he was not willing for extraction. Patient's persistent urge to save the tooth, put forth a challenge, which motivated us to tweak the established techniques. The unusual presentation of the case and unexpected par-operative condition of the surgical site required out-of-box measures to deal with the situation. Though, the tooth no. 14 was having Grade-I mobility, it was endodontically treated, buccal root was resected, osseous graft was applied over the deficient ridge area and lateral pedicle flap was displaced over the short root-trunk area to cover the surgical site. To our astonishment, the tooth survived, mobility was reduced and complete coverage with soft-tissue was observed. Uneventful healing with stable gingival margin was observed at 3-month interval, which remained stationary at 1-year follow-up.

Clinical evaluation of hydroxyapatite and ß-tricalcium phosphate composite graft in the treatment of intrabony periodontal defect: A clinico-radiographic study.

BACKGROUND AND OBJECTIVE: Hydroxyapatite (HA) and ß-tricalcium phosphate (ß-TCP) grafts have shown to be effective in promoting the clinical signs of periodontal regeneration in intrabony defects. The aim of our study was to clinically and radiographically evaluate the efficacy of HA and ß-TCP composite bone graft material in the treatment of intrabony three-wall defect. MATERIALS AND METHODS: Twenty patients participated in this study. Interproximal bony defects were surgically treated with a combination of HA-ßTCP (biphasic calcium phosphate). Changes in clinical parameters such as gingival status, probing pocket depth, clinical attachment, and radiographic estimation of the amount of bone fill were evaluated after 6 months postoperatively. STATISTICAL ANALYSIS USED: Student's "t" test. RESULTS: This treatment modality resulted in significant pocket depth reduction and clinical attachment gain which were observed to be 2.938 mm (47.04%) and 3.188 mm (29.09%), respectively. The defect fill as seen radiographically was 3.204 mm (63.195%). All the differences were highly significant and in favor of postoperative group. CONCLUSION: The results of this study suggest that HA-ßTCP (biphasic calcium phosphate) provides an added regenerative effect in promoting the clinical resolution of intrabony three-wall defects in patients with periodontitis.
