Smoking as a Risk Factor for Dry Socket: A Systematic Review.

Area of Science:

• Oral Surgery
• Dental Public Health
• Evidence-Based Dentistry

Background:

• Dry socket (alveolar osteitis) is a common and painful postoperative complication following tooth extraction.
• It involves the loss of the blood clot, exposing alveolar bone and causing significant discomfort.
• Understanding risk factors like smoking is crucial for patient management and prevention.

Purpose of the Study:

• To systematically review and synthesize the existing evidence on the relationship between smoking and the incidence of dry socket.
• To quantitatively assess the association between tobacco use and the risk of developing dry socket after tooth extraction.

Main Methods:

• A systematic review and meta-analysis were conducted following PRISMA guidelines.
• Eleven relevant studies were included after rigorous screening based on predefined inclusion and exclusion criteria.
• Data from these studies were pooled to calculate the overall odds and incidence of dry socket in smokers versus non-smokers.

Main Results:

• Tobacco smokers had a significantly higher risk, with more than a three-fold increase in the odds of developing dry socket.
• The overall incidence of dry socket was approximately 13.2% in smokers compared to 3.8% in non-smokers.
• This association remained consistent despite variations in study populations and extraction types.

Conclusions:

• Cigarette smoking is a significant risk factor for dry socket following tooth extraction.
• Patients who smoke have a substantially elevated risk of experiencing this painful complication.
• Public health initiatives and clinical advice should emphasize smoking cessation to mitigate dry socket risk.
