2023-11-06T10:15:49+07:00

Background: Aesthetic and functional dental restoration is a hope for people who have lost teeth, especially in the anterior region. Missing tooth 13 with more than 2 mm gingival recession can be made into a cantilever bridge restoration with the addition of porcelain gingiva. Gingival recession is when the tooth root surface is exposed due to periodontal tissue loss. Zirconia is a dental restoration material often used because of its biocompatibility, strength, and aesthetics. Purpose: To determine the procedure for making all porcelain cantilever bridge restorations in cases of gingival recession using zirconia material. Case analysis: The dental laboratory received a dental cast model of a 39-year-old female patient missing tooth 13 and had gingival recession on tooth 14 of more than 2 mm. Order in the form of restoration of all porcelain cantilever bridges from zirconia. Result: The cantilever bridge coping was made from zirconium dioxide and then layered with feldspathic porcelain to achieve optimal strength and aesthetics. A rest is made on tooth 12 to provide additional retention. Conclusion: The procedure for making all porcelain cantilever bridge restorations includes making diagnostic wax-up, scanning, coping design, milling, sintering, fitting, sandblasting, layering, anatomy, and glazing. Things that must be considered are the design, thickness of the coping, and connectors to achieve a restoration that is strong, resistant to fracture, and has good aesthetics. Porcelain gingiva was added in the cervical area of tooth 14 restorations to cover the recession

Background: Foodborne diseases are verry common and easily spread, among strains of Staphylococcus aureus, Bacillus cereus, Listeria monocytogenes, and Clostridium spp. Purpose: To isolate and characterize foodborne pathogenic bacteria and fungi in various foodstuffs. Method: A total of 260 samples (130 each from Peshawar and Mardan) were collected and analyzed. Only 61 tested positive for various types of bacterial and fungal pathogens. Then evaluated for their antibiotic/anti-fungal sensitivity patterns towards a panel of selected antibiotics and anti-fungal. Result: The Gram-positive isolates showed the highest resistance to methicillin (79%) and amoxicillin (63%), most sensitive to ceftriaxone (88%), levofloxacin (86%), and cefotaxime (77%). Intermediate activities were exhibited by azithromycin (50%) and vancomycin (55%). In terms of the Gram-negative bacteria, the best activities were shown by ciprofloxacin (100%), cefoxitin (100%), chloramphenicol (100%), and ceclor (100%). Intermediate activity was discovered for cefixime (50%), cefuroxime (50%), and linezolid (50%). Three anti-fungal drugs (fluconazole, voriconazole, and nystatin) were used to assess their potency against the fungal pathogens. Mucor spp. proved relatively more susceptible to all anti-fungal drugs. The only Fusarium spp. isolate was highly resistant to all anti-fungal in this research. Conclusion: The prevalence of Gram-positive bacteria is greater than Gram-negative bacteria in the current study. The frequency of fungal pathogens was relatively high in both raw and ready-to-eat foods, while packaged foods were free from fungal contamination. We recommend that appropriate safety when handling and cooking food. Moreover, food products should be screened for different pathogenic microbes.
