Histologic evaluation of the effect of nicotine administration on bone regeneration: a study in dogs

Abstract: ABSTRACT: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. The animals were randomly assigned to one of the following groups: Group 1 -control (n = 8) and Group 2 -subcutaneous nicotine administration (2 mg/kg) twice a day (n = 8). After 4 months, the animals were sacrificed and … Show more

“…Para Saldanha et al, a ação da nicotina sobre a regeneração óssea de defeitos criados cirurgicamente em rebordos alveolares nas mandíbulas de cães demonstrou que a administração de nicotina crônica influenciou significativamente na baixa densidade do tecido ósseo neoformado, tornando-o mais frágil (22) .…”

“…Pharmaceutical NIC available as chewing gum, transdermal patches, or microtablets are used in the replacement therapy for stopping smoking. Nicotine and its metabolites are also being investigated and researched for the treatment of a number of disorders, including Alzheimer's disease, attention deficit disorder and Parkinson's disease (Hecht, 2003;Baron, 1996) NIC has been shown to be detrimental to wound healing, vascularization, organ acceptance and general health (Saldanha et al, 2004). Nasal cavity has a very large mucosal surface and lined with the same columnar epithelium that lines the airways of the lung.…”
