A<unk>  (also termed lateral<unk> , or parietal<unk> , is a localized collection of pus (i.e. an<unk>  within the tissues of the periodontium. It is a type of dental<unk> . A<unk>  occurs alongside a tooth, and is different from the more common periapical<unk> , which represents the spread of infection from a dead tooth (i.e. which has undergone pulpal necrosis).

In contrast to a periapical<unk> ,<unk> es are usually associated with a vital (living) tooth.<unk> es of the periodontium are acute bacterial infections classified primarily by location.
