"The vaping patients were not asked whether they used devices that contained nicotine or THC, although nicotine is more common."

This is a bad study if they failed to control for THC vapes and nicotine e-cigarettes separately.

It is common knowledge that THC causes dry mouth, which increases the rate of tooth decay.

Indeed. This study is fatally flawed.

I kind of wish posting alleged discoveries was banned, and only replications could be submitted. Because most things posted here as new discoveries will not pan out in the end.

Given that about 6x more people use nicotine vaporizer products than THC products, and given the huge increase among the vaping group, it's pretty fair to say the results probably apply to the nicotine users. (Vaping e-juice containing propylene glycol and vegetable glycerin is also well-known to cause dry mouth, by the way.)

The study used data that existed prior to the start of the study. That doesn't make this a bad study, it just means the data is not comprehensive.

People like you use this sort of thing to try to make the researchers out as being incompetent, but that's far from fair. This is how science works. Patterns are noticed, then further investigation is done. This is not a bad study. It's valuable information and provides valuable insights. Further study inspired by this research will elucidate what we don't know.

It was easy for them to ask about marijuana use, and they could have excluded them from the study. There are better studies that do take this into account like this one:

This systematic review of studies highlights the problem https://pubmed.ncbi.nlm.nih.gov/36276349/

Conclusions: This review provides an update to the 2018 NASEM report on chronic health effects of e-cigarette use. While the number of studies has grown, the certainty of evidence remains very low largely because of cross-sectional designs and lack of reporting on exclusive e-cigarette exposure. There remains a need for higher quality intervention and prospective studies to assess causality, with a focus on exclusive e-cigarette use.

Both questions seem important. I keep waiting for solid research into the safety of vaping as a route of administration and separately the effects of the chemicals being vaporized and inhaled.

The use of unverified survey data as used in this paper is problematic enough that the CDC warns against it:

Also problematic is the potential confounding of E-methamphetamine, E-joint, and E-cigarette (nicotine) use. Methamphetamine is associated with severe adverse dental outcomes.

E-joints (THC) are potentially used by patients undergoing chemotherapy / radiotherapy with known impacts on factors related to increased dental caries:

Weird - I haven't had a cavity in decades. Started using ecig in 2008 - gave up sugar 2018 - no cavities in that decade between and none since either (yes I know that's n=1)

>Data from 13,216 patients were included in the data set initially; 13,080 responded “no” when asked whether they used e-cigarettes or vapes (99.3%), and 136 responded “yes” (0.69%). There was a statistically significant difference (P < .001) in caries risk levels between the e-cigarette or vape group and the control group; 14.5%, 25.9%, and 59.6% of the control group were in the low, moderate, and high caries risk categories, respectively, and 6.6%, 14.3%, and 79.1% of the e-cigarette or vape group were in the low, moderate, and high caries risk categories, respectively

Probably more like the "apple a day". Somebody who cares less enough about their health to smoke is also more likely to not brush his teeth properly - and vice versa. Just like the infant mortality is higher with parents that smoke. Not because of the smoke but because those parents are in general less careful with themselves and the kids. Numbers games that say nothing about the individual.

From this 2020 review, "Potential oral health effects of e-cigarettes and vaping: A review and case reports": https://vencedds.com/wp-content/uploads/2020/12/VAPING-PAPER-FIONA-DONOVAN-VENCE.pdf >There are currently over 10 000 commercially available e-liquid formulations 7 (Table 1). These formulations basically have three components: a base, nicotine, and flavors. All three of these components have the potential to negatively affect oral health.

they definitely ruin enamel and make it so people have worse attitudes since they can't guage nicotine intake accurately.
