This study analyzed the frequency of patients whose orofacial clefts diagnosed prenatally. Concordance of prenatal diagnosis and postnatal outcomes, and the impact of prenatal diagnosis.<br /><strong>Materials and methods: </strong>The sample was composed of 200 children (age of 0-36 months) relatives, with any orofacial cleft, regardless of ethnicity, gender, or socioeconomic background. A self-administered questionnaire responded, and descriptive statistics and Fisher exact test analyzed the results.<br /><strong>Results: </strong>Among the 200 children, 25.5% had diagnosed prenatally. There was concordance between prenatal diagnosis and outcome in 62.7% of cases, which is similar for all clefts (p=0.81). Less than entirely accurate prenatal diagnosis occurred in 37.2%. Under the 51 families that had a prenatal diagnosis, 66.6% considered the opportunity as favorable. Among the convenient reasons, 58.8% of the families mentioned the possibility to prepare themselves.<br /><strong>Conclusion: </strong>One-quarter of patients diagnosed prenatally and less than entirely accurate findings occurred in more than a third of the cases diagnosed. Despite that, families often report prenatal diagnosis as helpful for the acceptance of the condition and psychological preparation before the child is born.Tehran: International Journal of Scientific Research in Dental and Medical SciencesInternational Journal of Scientific Research in Dental and Medical Sciences2676-54971320190901Incidence and Risk Factors of Retinopathy of Prematurity in Khatam Al-Anbia Ophthalmology Hospital in Mashhad City36399204610.30485/ijsrdms.2019.192413.1008ENNafiseh Kazemi RadSchool of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran0000-0001-6333-1569Maliheh Akbari FarkhaniSchool of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran0000-0003-0369-9411Majid AbrishamiRetina Research Center, Department of Ophthalmology, Mashhad University of Medical Sciences, Mashhad, Iran0000-0002-4696-3350Naser ShoeibiEye Research Center, Khatam-al-Anbia Hospital, Mashhad University of Medical Sciences, Mashhad, Iran0000-0003-3544-0105Elham BakhtiariEye Research Center, Mashhad University of Medical Sciences, Mashhad, Iran0000-0002-1582-3961Journal Article20190701<strong>Background and aim: </strong>Retinopathy of prematurity (ROP) is a complex disease initiated by abnormal retinal vascularization in premature infants.

It can be constrained to the crown or extent the root and influence the periapical area.<br />The condition seen in the radiographic image is usually like a tooth within a tooth. Although it happens rarely, it is the most frequent malformation detected in human dentition. It can be specially observed in maxillary lateral and then central incisors. Because of the complexity as well as strange anatomy, the tooth has the potential to reveal pulp necrosis and open apex, which may bring about some challenges to manage it. Early detection of the malformation is critical for better handling and makes treatment plans more conservative, like restorative procedures.<br />We described the management of an uncommon case of type III dens in dente diagnosed using a cone-beam CT scan in a maxillary lateral incisor. The patient had a chronic periapical lesion, a buccal sinus tract, and palatal expansion, which were healed successfully after treating with non-surgical root canal procedure.
