The effect of traditional and heated tobacco products on periodontal health: A cross- sectional observational study
This cross-sectional study found that while non-smokers exhibited the most favorable periodontal health, both traditional cigarette smokers and heated tobacco product users demonstrated similarly compromised periodontal parameters, including increased pocket depth, bleeding on probing, and gingival crevicular fluid volume.

Imagine your gums and the bone holding your teeth are like a well-tended garden. In a healthy garden, the soil (bone) is firm, the grass (gums) is green and tight, and there's no unwanted weed growth (pockets).
This study is like a garden inspection comparing three groups of people:
- Traditional Smokers: People who burn tobacco in cigarettes.
- Heated Tobacco Users: People who use new devices (like IQOS or glo) that heat tobacco sticks instead of burning them.
- Non-Smokers: People who don't use any tobacco.
The researchers wanted to see if the "heated" version of tobacco was actually a gentler breeze for the garden, or if it was just a different kind of storm.
The Big Surprise: The "Heated" Garden Isn't Safe
The main finding is a bit of a shocker for anyone thinking heated tobacco is a "safe" alternative. The study found that the gardens of the Heated Tobacco Users looked almost exactly the same as the gardens of the Traditional Smokers. Both groups had more damage than the Non-Smokers.
It's as if the heated device is a different type of sprinkler that still sprays water, but the water is just as damaging to the soil as the water from the burning cigarette.
What the Researchers Found (The Garden Inspection)
1. The "Plaque" (Dirt on the Leaves)
- What it is: A sticky film of bacteria on teeth.
- The Result: Traditional smokers had the dirtiest leaves (highest plaque). Heated tobacco users had more dirt than non-smokers, but the difference wasn't quite big enough to be statistically "loud" in this specific group. However, both smoker groups were dirtier than the non-smokers.
2. The "Pockets" (Holes in the Soil)
- What it is: When gums pull away from teeth, they create deep pockets where bacteria hide.
- The Result: Both smoker groups had significantly more of these deep pockets than non-smokers. Even though the average depth wasn't huge, the number of these trouble spots was much higher in the smoker groups. It's like finding many small holes in the soil rather than one giant crater.
3. The "Bleeding" (The Garden's Alarm)
- What it is: When you gently probe the gums, do they bleed? This is a sign of inflammation.
- The Result: Interestingly, the study didn't find a huge difference in bleeding between the groups. The researchers suggest this might be because nicotine acts like a "numbing agent" or a tight clamp on blood vessels, hiding the bleeding even when the tissue is angry. However, the heated tobacco group actually showed the highest bleeding numbers, suggesting their inflammation was fighting hard against that numbing effect.
4. The "Fluid Volume" (The Sweat of the Garden)
- What it is: The study measured Gingival Crevicular Fluid (GCF), which is like the "sweat" or fluid leaking from inflamed gums.
- The Result: This is a key finding. The heated tobacco users had significantly more of this fluid than non-smokers. This is a clear sign that their gums are in a state of inflammation, even if they don't look terrible on the outside. It's like the garden is sweating profusely because it's under stress.
5. The "Bone Loss" (The Foundation)
- What it is: The actual bone holding the teeth.
- The Result: Surprisingly, no one had lost significant bone yet. The researchers note this is likely because the participants were quite young. It's like checking a house's foundation in a brand-new building; the damage hasn't had enough time to show up yet, even if the walls are already cracking.
The "Heavy" vs. "Light" Smoker
The researchers also looked at who smoked more. They found that the "Heavy Smokers" (those using 10+ sticks/cigarettes a day) had the most deep pockets. However, even the "Light Smokers" had more signs of gum inflammation (the fluid and the 3mm pockets) than non-smokers. It seems that any amount of tobacco use, whether burned or heated, starts to disturb the garden.
The Bottom Line
The study concludes that heated tobacco products are not a risk-free escape. They cause just as much gum inflammation and pocket formation as traditional cigarettes.
The researchers warn that while these products might feel "cooler" or less harsh, they are still sending a warning signal to your gums. The garden is stressed, the soil is disturbed, and the fluid is rising. The only group with a truly healthy, calm garden was the non-smokers.
Important Note: The researchers admit this is a snapshot in time (like taking one photo of the garden). They can't say for sure what will happen in 20 or 30 years, but the early signs are already worrying. They also noted that because heated tobacco is new, they couldn't find many people who only used it and never touched a cigarette before, so the study focused on younger users.
