Myiasis is an infestation of living or dead tissue of humans and animals by diptera larvae. Gingival
myiasis is a rare pathology and is mainly associated with poor
oral hygiene,
alcoholism, senility, suppurative lesions,
mouth breathing,
mental retardation and
hemiplegia.
Myiasis is most common during summer since the fly population increases during this season. Mostly it occurs in farmers and people who live in tropical climates. Gingival
myiasis in humans in Turkey is limited to only a few cases. According to our literature research, this is the first case of gingival
myiasis produced by larvae of Wohlfahrtia magnifica in a Turkish adult. According to our best knowledge, it is also the first gingival
myiasis case that one of the causative larva had grown to the adult stage in Turkey. A 43 years old male patient who perceived the presence of live maggots in his mouth was referred to our clinic. Clinical findings of gingival
myiasis were observed. The patient had no history of systemic disease but
oral hygiene was poor. Clinical and radiographic examination indicated that he had
chronic periodontitis. Before the dental treatment seven larvae and during the scalling five larvae were elevated from the gingival sulcus. The body of the larvae composed of 12 segments and they were 8-10 mm in length. One of the larvae which was sent to the microbiology laboratory were placed into sheep liver to resume life and the other larvae were placed into 70% alcohol
solution. After 9-10 days, the larva which was placed in the liver became pupa. Approximately 15 days later, the pupa became an adult fly. The larvae were identified as the second stage larvae of Wohlfahrtia magnifica. Treatment consisted of removal of the maggots from the gingival sulcus, followed by scaling and
oral hygiene instruction. Non-surgical periodontal treatment was applied and the patient was followed-up for 3 months. After non-surgical periodontal treatment, patient didn't accept the flap operation. The most important point for the prevention of gingival
myiasis is to establish a good
oral hygiene, together with the elimination of environmental factors which support the proliferation of the flies.
