Title of Symposium: Smoking and Dental Implant
Speakers: Dr Mariam Ghanbariha, Dr Yad Zangana and Assist Prof Dr Faraedon Zardawi
First Speech: What is so cool about smoking
By Dr Mariam Ghanbariha
Although cool, glamorous and fun had been the lore of cigarette advertising for decades but the truth is tobacco smoking is the largest preventable risk factor for illness in developed countries; smoking accounts for approximately 20% of deaths. It is a mistake to think that using nicotine in a form that doesn’t involve cigarettes is harmless. Products like smokeless tobacco and electronic cigarettes may be considered less harmful when compared to cigarette smoking, but they carry considerable health hazards as well. Continued efforts are necessary to reduce the social acceptability of tobacco product use and protect bystanders from all tobacco product emissions. Increased awareness of the adverse, lifetime consequences of tobacco smoking may facilitate the development of community health interventions to robust public health policy.

Third speech: Negative influences of smoking on the survival rate of dental implant
By Assis Prof Dr. Faraedon M. Zardawi
Dental implants have become a safe and effective therapeutic option for replacing missing teeth in partially and fully edentulous patients with 90% survival rate of various clinical situations. Rate of success and failure varied according to level of risk factors, smoking is a prevalent behavior in the population that influences general as well as oral health of an individual. It is considered a detrimental risk factor for implantation. The failure rate of implant osseointegration is considerably higher among smokers, furthermore, maintenance of oral hygiene around the implants and the risk of peri-implantitis and marginal bone loss are adversely affected by smoking. The negative effect of smoking is due to cytotoxicity and/or vasoconstriction effect of (nicotine, carbon monoxide, and hydrogen cyanide) tobacco constituents to the cells involved in wound healing and compromised polymorphonuclear leukocyte function. A recommended protocol to increase implant survival among smokers is proposed based on cessation of smoking at least 1 week prior to surgery and continuing to avoid tobacco for at least 2 months after implant placement by which time bone healing would have progressed to the osteoblastic phase and early osseointegration would have been established. In high-risk situation, dentist should decide whether or not commence implantation, but once the decision made to go ahead, the patient’s informed consent is necessary before starting treatment.
