Histological and dimensional changes of the alveolar ridge following tooth extraction when using collagen matrix and collagen-embedded xenogenic bone substitute: A randomized clinical trial.

Aim: To assess the horizontal and vertical dimensional changes of the alveolar ridge when using a collagen matrix in combination with collagen embedded xenogenic bone substitute, in comparison with natural healing after tooth extraction.

Methods: Patients that required extraction in non-molars areas were included. Test group-15 sockets were treated with deproteinized bovine bone mineral containing 10% collagen (DBBM-C), covered by a procaine collagen membrane (CMXs).

Esthetic Mucogingival Treatment After Biopsy of Inflammatory Fibroepithelial Hyperplasia.

Introduction: This case reports a biopsy of a large soft tissue defect with gingival grafting. The therapeutic approach presented here combines a partly de-epithelialized free gingival graft (PDFGG) with an envelope technique, which may be useful for cases needing a large reactive lesion biopsy.

Case Presentation: A patient with an esthetic and functional complaint due to a fibroepithelial hyperplastic lesion was treated by excisional biopsy leaving a 10 mm cervical defect on tooth 23.

Acrylic orthodontic retainer is not a risk factor for focal Candida colonization in young healthy patients: a pilot study.

Background: Denture enhances the risk of Candida colonization because of adherence to acrylic base and interference with salivary rinsing. Acrylic orthodontic appliances may also create retentive areas for food debris and microbial pathogens; moreover, patients are instructed to use the retainers at night, when salivary secretion is reduced. We studied the Candida colonization in orthodontic patients using acrylic retainer.
