Anxiety is a complex phenomenon which can become a risk factor for suppression of many functions of the body. AIM: The aim of this study was to investigate the effect dental anxiety exerts on the choice of method of treat- ment by patients wanting to have dental implants. MATERiaLS AND METHODS: The study included 174 patients that were referred to us for dental implants placement because of partial or total loss of teeth. Their dental anxiety was measured using the Dental Anxiety Scale (DAS) proposed by Norman Corah. The patients decided to have or refused to have treatment with dental implants either because they had dental anxiety or gave other reasons. RESULTS: Distribution of patients by level of anxiety was as follows: 33% were anxiety free, in 34% the dental anxiety was moderate, 25% had severe anxiety, and 8% experienced an extremely severe anxiety. Dental fear was given as a reason for refusal of treatment by 24.1% of the patients wanting to have dental implants. Of the patients wanting to have dental implants, 40.8% decided to proceed with the treatment; these patients exhibited low dental anxiety. CONCLUSION: The decision to have dental treatment with implants is affected by the patient’s level of dental anxiety. Only those with low level of dental anxiety decide to proceed with such a treatment. The mild anxiety some patients experience is beneficial as it eliminates a risk factor that may hinder the process of osseointegration. Key words: anxiety, dental anxiety, treatment, dental implants, implants Folia Medica 2015; 57(2): 116-121 Copyright © 2015 Medical University, Plovdiv РЕЗЮМЕ ВВедение: В современной стоматологической медицине всё чаще применяются стоматологические имплантаты в качестве опор для протетических восстанавливаний. Многомерная в своей сущности тревожность является фактором риска для подавления многих функций организма. Цель: Целью настоящей работы является исследование влияния стоматологической тревожности на выбор метода лечения пациентами, которые желают установление стоматологических имплантатов. Материал и Методы: Объектом исследования стали 174 пациента, обратившиеся за помощью по поводу лечения частичной или полной потери зубов при помощи стоматологических имплантатов. Оценка стоматологической тревожности осуществилась при помощи DAS шкалы Norman Corah. Пациенты выбирали имплантологическое лечение или отказывались от него по причине стоматологической тревожности или по другим причинам. результаты: Распределение участников в зависимости от степени тревожности следующее: у 33% отсутствует тревожность, у 34% наблюдается умеренный уровень тревожности, у 25% проявляется сильный уровень тревожности, у 8% установлен исключительно сильный уровень тревожности. 24.1% из числа желающих установить стоматологические имплантаты отказываются от лечения по причине страха. Выбравшие лечение при помощи стоматологических имплантов пациенты составляют 40.8% с низким уровнем тревожности. заключение: Выбор пациентом лечения с установлением стоматологических имплантатов зависит от уровня тревожности. Данное заключение является благоприятным фактом, так как устраняет один из факторов риска, который может привести к подавлению процессов остеоинтеграции.
