The reason for higher incidence of dry socket in the 3rd decade may be due to the higher frequency of pericoronitis which is identified as a risk factor for dry socket.25

(2) The reason for these extractions is the high incidence of impaction, often associated with a number of oral problems, such as pericoronitis, periodontal defects in the distal region of the second molar, caries in the third or second molars, different types of odontogenic cysts and tumors, and crowding of the lower incisors.
Frequency of dental The indicator was obtained by calculating the emergencies percentage of dental emergency consultations in primary health care (i.e., pulpal pain, acute periapical abscess, pericoronitis, periodontal abscess, dental trauma, etc.) relative to the total number of dental consultations in primary health care.
If they erupt, they may be beneficial for orthodontic anchorage, prosthetic abutments, or transplantation.8 If they get impacted, they can cause adjacent root resorption, inflammatory process (pericoronitis), temporomandibular joint dysfunction and late incisor crowding;9 thus prophylactic removal greatly reduces risk to a patient as opposed to extraction later in life.10 Early germectomy can also reduce the risk of intra-operative and post-operative complications associated with surgery on a fully developed third molar such as nerve damage with resultant paresthesia, dry socket, inflammation, bleeding, and pain.11 Therefore, assessment of germ position and progress of mandibular third molar eruption is necessary for better patient management.
