Statement of the problem Traumatic dental injury (TDI) is a current issue in public health (Milani et al, 2019). About one-third of children worldwide suffer from traumatic dental injuries (TDI), it has epidemiological significance. Throughout the child's growth and development, new and repetitive trauma may happen, influencing the dental, periodontal, bone, and soft tissue structures (Carneiro et al, 2020).~In young children, enamel fracture is the most frequent tooth injury, and this kind of trauma could go undetected by the child's parents, caregivers, or anybody else. The deciduous dentition has received a little amount of research on trauma (Carneiro et al, 2020).~Depending on the intensity of the consequences, dental trauma can have a significant impact on a child's life. It can cause discomfort and trouble chewing, as well as alter dento-facial aesthetics and, consequently, the person's ability to connect socially (Carneiro et al, 2020).~Systematic reviews have found that TDI affects pre-schoolers' oral health-related quality of life (OHRQoL). Children and their families suffer emotional and social consequences as a result (Antunes et al, 2020), (Zaror et al, 2018).~Risk factors, the impact of TDI, and the relation between TDI and socioeconomic status should all be considered (Antunes et al, 2020).~The purpose of this study is to assess the impact of dental trauma on children's and their families' oral health-related quality of life (OHRQoL), considering clinical and socioeconomic factors.~Rationale TDI cannot be anticipated and frequently requires emergency care due to its nature. Although it can happen at any age, the majority of TDI occurs in children. Literature reviews indicate that TDIs affect between one-third and one-fourth of kids in the primary dentition age range [(Jadav& Abbott, 2022), (Almeida et al, 2021)].~Due to the anatomical proximity of the germs of the permanent successors and the potential for adverse sequelae in both dentitions, TDI in the deciduous dentition requires extra care and attention. Therefore, the severity and extent of TDI can have an impact on the development of permanent successors as well as the prognosis of deciduous teeth (Antunes et al, 2020), (Andreasen et al, 2018).~Settings~• Location: preschool Nurseries in some rural areas in Elmaadi- Cairo.~Methodology:~Preschool children whose age ranged from 2 to yonger than 6 in some nurseries will be examined for traumatic dental injuries in anterior teeth.~Examination will be performed in a room under natural light, with the help of wooden spatulas and gauze, by a single, trained and calibrated examiner.~Type of tooth and the severity of TDI will be classified according to Glendor classification (Glendor et al, 1996) and will be recorded.~The classification of Glenndor: Uncomplicated tooth injuries: in which the pulpal tissue are not exposed and/ or tooth is not dislocated. And Complicated tooth injuries: in which the pulpal tissue are exposed and/ or tooth is dislocated~The author then will apply ECOHIS questionnaire on parents of children exposed to TDI after acceptance of informed consent.~The questionnaire was developed by (Pahel et al, 2007)~The questionnaire was then translated into Arabic and validated by (Nada Farsi et al, 2017).
