Title |
Inconclusive Evidence on Causal Relationship Between Alcohol-Containing Mouthwash and Oropharyngeal Cancer |
Clinical Question |
Does a dental patient who uses alcohol-containing mouthwash have an increased incidence of oropharyngeal cancer than one who uses non-alcohol containing mouthwash? |
Clinical Bottom Line |
Available evidence is inconclusive. (See Comments on the CAT below) |

Comments on
The Evidence |
This is a systematic review of 9 cases and controls, not randomized controlled trials. The article makes no mention as to whether the individual studies were assessed for validity. The article discussed 7 trials with a total of more than 1,897 patients. A meta-analysis could not be performed due to the heterogeneity of the studies. |
Applicability |
A potential patient benefit is peace of mind for patients using alcohol-containing mouthwashes, knowing that a causal relationship has not been established. However, since no randomized controlled clinical trial or longitudinal study have investigated the safety of the long-term use of alcohol-containing mouthwashes, the available results could potentially give a false security in using a product that may one day be shown to increase the risk for oropharyngeal cancer. |

by Alexander Padalino (San Antonio, TX) on 09/28/2022 I found an update article on this topic (Argemi et al. 2020, PubMed ID: 32473798). This was a meta-analysis and systematic review of 11 case-control studies and 3 clinical trials. The results agreed with previous reports that there is not sufficient evidence to accept any proposal that alcohol containing mouth rinses increase the risk of oral cancer. | by Amber O’Connor (San Antonio, TX) on 04/16/2012 In a PubMed search done on this topic in April 2012 I found a more recent publication: PubMed: 18952488. A systematic review of 10 case-control studies found the same key results as this CAT and further confirms the evidence that there is not a relationship between alcohol-containing mouthwash and oral cancer. | |
