Summary
Smokers are three times more likely to have root-filled teeth (RFT) extracted compared to non-smokers. This systematic review suggests smoking is a negative prognostic factor for root canal treatment outcomes, despite low-quality evidence.
Area of Science:
- Endodontics
- Public Health
- Dental Research
Background:
- Root-filled teeth (RFT) extraction is a concern in endodontic treatment.
- The impact of smoking on RFT outcomes requires further investigation.
Purpose of the Study:
- To systematically review and meta-analyze the association between smoking habits and the extraction of RFT.
- To determine if smoking influences the prevalence of RFT extraction.
Main Methods:
- A systematic literature search was conducted across multiple databases (MEDLINE/PubMed, Wiley, Web of Science).
- Data were analyzed using a random effects model for cumulative meta-analysis.
- Risk of bias and certainty of evidence were assessed using Cochrane and GRADE systems.
Main Results:
- The meta-analysis included data from two studies comprising 516 RFT.
- Smokers had a significantly higher odds ratio (OR = 3.43) for RFT extraction compared to non-smokers.
- The certainty of the evidence was assessed as low, with a moderate risk of bias in the included studies.
Conclusions:
- Tobacco smoking is a negative prognostic factor for root canal treatment success.
- Smokers' RFT are three times more likely to be extracted, indicating increased risk of failure.
- The low quality of evidence necessitates caution when interpreting these findings.

01:15Teeth
The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...

01:21Tooth Anatomy
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.

01:29Stimulants
Stimulants are substances that enhance neural activity and elevate dopamine levels in the brain, leading to their highly addictive nature. These drugs include cocaine, amphetamines, MDMA, caffeine, and nicotine, each with distinct mechanisms of action and varied health implications.
Cocaine can be administered via snorting, injection, or smoking. It primarily functions by blocking the reuptake of dopamine, resulting in a euphoric high characterized by an intense sensation of happiness and...
