Tooth injuries are serious clinical conditions. Some children experience dental trauma only once, while others are more prone to repeated tooth injuries. Repeated dental trauma occurs in 19.4% to 30% of patients. Pain and dental trauma are the most common reasons for fear and anxiety. The main objective of this study was to investigate how dental trauma, as well as repeated dental trauma affects the occurrence and development of dental fear in children. The study was conducted on a random sample of 147 subjects (88 boys and 59 girls) aged 5-8 and 9-12 years. Subjects in both age groups were divided into subroups without dental trauma, with one dental trauma and with repeated dental trauma. The validated Children’s Fear Survey Schedule – Dental Subscale was used on fear assessment. Results showed that only 12.2% of children without trauma, 33.3% with one trauma and 51.7% with repeated trauma were not afraid of injection. Older children had a significantly lower fear of injections, touch of an unknown person, choking, going to the hospital and people in white uniforms. Dentist was not the cause of fear in 65.5% of patients with repeated trauma. With each repeated injury of teeth, the degree of their fear of dental treatment was lower.

Ozljede zubi su ozbiljno kliničko stanje. Neka djeca doživljavaju dentalne traume samo jednom, dok su druga sklonija ozljedama i ponavljanju trauma zubi. Ponovljene traume zuba javljaju se u 19,4% do 30% bolesnika. Bol i trauma zuba su najčešći razlozi straha i tjeskobe. Glavni cilj ovoga istraživanja bio je ispitati kako zubna trauma utječe na pojavu i razvoj dentalnog straha. Istraživanje je provedeno na slučajnom uzorku od 147 ispitanika (88 djevojčica i 59 dječaka) u dobi od 5-8 i 9-12 godina. Ispitanici u obje dobne skupine podijeljeni su u tri poskupine: bez dentalne traume, s jednom dentalnom traumom i s ponovljenom dentalnom traumom. U procjeni straha korišten je validirani test Children’s Fear Survey Schedule – Dental Subscale test. Starija djeca su imala značajno niži stupanj straha od injekcija, dodira nepoznate osobe, gušenja, odlaska u bolnicu i ljudi u bijelim uniformama. Strah od stomatologa nije imalo 65,5% djece s ponovljenom traumom. Samo 12,2% djece bez trauma, 33,3% s jednom i 51,7% s ponovljenom traumom se ne boje injekcije. Sa svakom ponovljenom ozljedom zuba stupanj njihovog straha od stomatološkog liječenja je manji.
