Aim: This study aimed to assess the correlation between dental anxiety, state anxiety and pain after dental injection. Materials and methods: 120 children with positive rating according to Frankle behavior scale were enrolled in this cross-sectional study, each child received a maxillary injection prior treatment. Dental anxiety was assessed by Children Fear Scale, and state anxiety was assessed by the Children Anxiety Questionnaire. The Wong Baker Scale and FLACC Scale were used to measure pain after dental injection. Results: No statistically significant differences were found in anxiety level scores between genders and age groups with p-value > 0.05. A statistically significant difference in the postoperative pulse rate between males and females, with females having a greater mean pulse rate (p value= 0.024). A positive correlation was found between each dental anxiety and procedural pain and state anxiety and procedural pain. Conclusion: Decreasing anxiety levels in young patients reduce the expected pain and procedural pain experienced by children which results in a better health care and quality of life.
