ABSTRACT                                                              Loss of consciousness is one of the most common medical emergencies during dental interventions. Syncope, transient ischemic attacks, epileptic seizures and nonepileptic psychogenic events can induce loss of consciousness. Reflex epilepsy is characterized by seizures accompanied by loss of consciousness that are triggered in response to a specific external or internal stimulus. Our aim was to report of a reflex epilepsy case triggered by dental treatment.In this paper, a 22-year-old ASA I male patient developing loss of consciousness with generalised tonic-clonic seizures, severe bradycardia and asystole during dental treatment is presented. He was diagnosed with reflex epilepsy. The reflex epilepsy was thought to have been triggered by hyperventilation resulting from dental anxiety and fear.Special consideration must be given to the differential diagnosis for conditions leading to loss of consciousness. Reflex epilepsy should be considered in cases during which loss of consciousness accompanied by/followed by convulsive seizures has occurred while the patient was exposed to specific external and internal stimulus.Key words: Dentistry; emergency treatment; epilepsy, reflexDENTAL TEDAVİ İLE TETİKLENEN REFLEKS EPİLEPSİ: BİR OLGU BİLDİRİMİÖZET  Bilinç kaybı diş hekimliği işlemleri esnasında sıklıkla oluşabilen acil tıbbi durumlardan biridir. Senkop, geçici iskemik ataklar, epileptik nöbetler ve epileptik olmayan psikojenik olaylar nedeniyle bilinç kaybı oluşabilmek- tedir. Refleks epilepsi belirli eksternal veya internal uyarılara bağlı olarak oluşan bilinç kaybının eşlik ettiği nöbetlerle karakterizedir.  Amacımız dental tedavi ile tetiklenen refleks epilepsi vakasını bildirmektir.Bu makalede 22 yaşında ASA I erkek hastada diş tedavisi esnasında tonik-klonik jeneralize nöbet, ciddi bradikardi ve asistol oluşumu ile birlikte gelişen bilinç kaybı olgusu sunulmaktadır. Hasta refleks epilepsi olarak teşhis edilmiştir. Refleks epilepsinin dental kaygı ve korkudan kaynaklanan hiperventilasyon nedeniyle tetiklendiği düşünülmektedir.Bilinç kaybına yol açan durumların ayırıcı tanılarına özel dikkat gösterilmelidir. Hastaların belirli eksternal ve internal uyarılara maruz kaldığı durumlarda bilinç kaybı eşliğinde/takibinde oluşan konvülsif nöbet olgularında refleks epilepsi göz önünde bulundurulmalıdır.Anahtar kelimeler: Acil tedavi; diş hekimliği; epilepsi, refleks
