Dental erosion, alveolar bone destruction and oral/pharyngeal lesions · Rat models with surgically induced or chronic acid gastroesophageal reflux
In experimental rat models, induced gastroesophageal reflux caused dental erosion, alveolar bone destruction and oral lesions compared with controls, supporting biological plausibility; evidence is ungraded animal research.

Oral health effects of botulinum toxin treatment for drooling: a systematic review. 2020 All outcomesBefore vs after BoNT injection (2018 study: significant buffering increase at 1 month; 2017 study no change) · Neurological-disease populations with drooling (e.g., cerebral palsy, Parkinson disease, adults with sialorrhea); specialist clinical care
The quasi-experimental studies of Tiigimae-Saar found different results concerning the changes in buffering capacity. For the analysis carried out in 2017, no statistically significant change was observed. By contrast,…
