−*A more virulent infection into the alveolus produces alveolar periostitis. +
−*Abscess may break through into maxillary sinus. If drained will get recovery.
−**Other maxillary cheek teeth can be involved in pyaemic infection with sinus formation.
*Infection spreads from [[Enamel Organ#Pulp|pulp]] or from gingivitis to produce the periostitis.
+*Infection and inflammatory mediators usually spreads from [[Enamel Organ#Pulp|pulp]] to produce the periostitis.
−*This may then break out of the alveolus into the bone causing [[Osteomyelitis|osteomyelitis]].
+*This may then affect the surrounding bone causing [[Osteomyelitis|osteomyelitis]].
