Enamel matrix derivative versus guided tissue regeneration in the presence of nicotine: a histomorphometric study in dogs.

Aim: The goal of this histometric study was to compare the healing process of dehiscence-type defects treated by enamel matrix derivative (EMD) or guided tissue regeneration (GTR) under the effect of nicotine in the dog model.

Materials And Methods: Eight mongrel dogs were used. Buccal osseous dehiscences were surgically created on the mesial roots of the mandibular third and fourth pre-molars.

Smoking may affect the alveolar process dimensions and radiographic bone density in maxillary extraction sites: a prospective study in humans.

Purpose: Loss of ridge width and height typically occur after tooth extraction. This study aimed to investigate whether smoking would effect alveolar ridge remodeling after tooth extraction.

Materials And Methods: Twenty-one individuals (11 nonsmokers, 10 smokers) requiring a nonmolar extraction in the upper jaw were selected.

Coronally positioned flap with or without acellular dermal matrix graft in gingival recessions: a histometric study.

Purpose: To evaluate, histometrically, the healing of gingival recession treated by coronally positioned flaps (CPF) with or without acellular dermal matrix (ADM) as a subepithelial graft.

Methods: Gingival recessions were created on the upper cuspids of six dogs and were randomly assigned to: CPF+ADM (ADM group) or CPF alone (CPF group). After 4 months, the dogs were sacrificed, and the histometric measurements were performed.

Histologic evaluation of the effect of nicotine administration on bone regeneration. A study in dogs.

The objective of this study was to investigate the histometric impact of nicotine on bone regeneration of surgically created alveolar ridge defects in dogs. Sixteen mongrel dogs were used. One defect was surgically created unilaterally in the mandible, and left to heal spontaneously.

Enamel matrix derivative and guided tissue regeneration in the treatment of dehiscence-type defects: a histomorphometric study in dogs.

Background: The goal of this investigation was to histologically and histometrically evaluate the healing process of dehiscence-type defects treated by enamel matrix derivative (EMD) and/or guided tissue regeneration (GTR).

Methods: Seven mongrel dogs were used. Buccal osseous dehiscences were surgically created on the mesial roots of the mandibular third and fourth premolars.

Guided bone regeneration may be negatively influenced by nicotine administration: a histologic study in dogs.

Background: A series of animal and in vitro data confirms that nicotine impairs bone healing, diminishes osteoblast function, and causes autogenous bone graft morbidity. Therefore, this study aimed to investigate the impact of nicotine on the healing of bone defects treated by the guided bone regeneration (GBR) principle.

Methods: Sixteen mongrel dogs were used.
