Microbiological evaluation of an experimental denture cleanser containing essential oil of .

The antimicrobial activity of an experimental solution containing essential oil of for denture cleaning was evaluated by (1) minimum inhibitory (MIC) and fungicidal/bactericidal concentration (MFC/MBC) tests against , , and ; (2) the metabolic activity of biofilm formed on flat-bottom microplates and denture base specimens based on the reduction of 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT); and (3) scanning electron microscopy, to evaluate the fungal biofilm morphology. The solution showed antimicrobial action against the pathogens tested ( - MIC and MFC: 19.53 µg ml, - MIC and MBC: 78.

Combining different ceramic systems and periodontal microsurgery in maxillary esthetic areas: a case report.

Oral rehabilitations in esthetic regions may be challenging when different prosthodontic modalities must be combined with interventions on gingival tissues to create a harmonious smile for the patient. This case report describes the treatment of a 36-year-old man with an esthetically compromised maxillary anterior region by means of periodontal microsurgery, an implant-supported dental prosthesis, and tooth-supported crowns. Combined esthetic-functional planning based on clinical and radiographic examinations, photographs, and a diagnostic wax-up led to correction of the gingival contour and thickness by means of periodontal microsurgery; customization of an implant-supported zirconia abutment with the application of feldspathic porcelain; fabrication of a lithium disilicate ceramic infrastructure to mask darkened substrate; and fabrication of lithium disilicate ceramic definitive restorations.
