“…A review of the literature, from 1973 until August 2023, reveals a total of 44 reported cases of pneumomediastinum following a single dental extraction, usually resulting from the use of high-speed dental drills, which is designed for cutting teeth and uses air or air and water to cool the dental bur [ 1 , [5] , [6] , [7] , [8] , [9] , [10] , [11] , [12] ]. The mandibular molars are more frequently involved, which is not only supported by the presented case, but also by 21 of the 33 cases (63.6 %) reported by Spille et al [ 2 , 5 ]. In particular the removal of the second and third molar from the lower jaw seems to be the main reason for development of mediastinal emphysema.…”
