**3. Teeth involved in fascial infections**

Invasive dental manipulation is known to cause bacteremia and generally considered highrisk procedures for the spread of infection in susceptible patients.[31-48] Sato et al., has shown that the main origin of maxillofacial infections were odontogenic (79.31%), fol‐ lowed by trauma (10.7%), immunosuppression (1.6%), pathologies (1.6%), and other causes (8%).[49] Seppänen et al., also reiterated that the most common dental procedures that precede odontogenic infection complications are: tooth extraction (60%), endodontic treatment (20%), dental implant surgery (8%), restorative treatment (8%) and dental plaque and calculus removal (4%).[50-52]

Lower third molars are more frequently involved in odontogenic infections when compared with other teeth. Flynn et al., presented in their prospective study with 37 consecutive hospitalized patients, a 68% prevalence rate of this group of teeth in association with odonto‐ genic infections, followed by other lower posterior teeth (premolars, first and second molars), without anterior teeth involvement.[13] Third molar removal is one of the most regular dentoalveolar surgical procedures.[10, 26, 52-65] With an 80% prevalence of retained third molars in the adult population,[23] appropriate treatment, and especially prophylactic third molar removal remains a key focus of interest in healthcare with both medical and economic dimensions. It is generally accepted that substantial risks may arise both from third molar removal,[6, 29, 37, 60, 66, 67] as well as from a "wait and see "policy.[4, 11, 14, 25, 33, 44, 65]
