Abstract
Panoramic radiographs are complementary exams to evaluate oral alterations in an early manner, these changes can be dental developmental anomalies, and post-eruption dental disorder. Aim: This study evaluated the findings in panoramic radiographs and correlated the variables of gender and dental location. Methods: A retrospective study was through the observation of 1.111 panoramic radiographs from the Radiology Department in Brazil. It was included patients from 5 to 79 years of age of both gender, and it classified the anomalies in shape, size, and number and post-eruption dental changes in and correlated with gender and location. Patients with syndromes were excluded from the sample. Results: The majority of the sample was composed of fameles 752 (67.7%), as to the frequency of dental developmental anomalies related lesions 684 cases (61.6%) and post-eruption dental disorder 567 (51.8%), in the radiographs. The most prevalent change was endodontic treatment (32.6%), followed by root dilaceration (25.9%), and included tooth (19.5%). The most prevailing alteration when correlated with the gender variables was the cyst root (p<0.01) in females, and orthodontic treatment (p=0.02) in males and the variable location in the mandible was root dilaceration, giroversion, impacted tooth, taurodontia, microdontia, and endodontic treatment (p<0.01). Conclusion: Our findings provide evidence that dental developmental anomalies e post-eruption dental disorder are frequent alterations in the population with particular characteristics of distribution by sex and location.
Highlights
Panoramic radiography is an extraoral procedure of simple execution, in which it visualizes the whole maxillo-mandibular complex[1,2,3]
Dental developmental anomalies (DDA) and post-eruption dental disorder (PEDD) are the radiographic findings that the early diagnosis that can occur with the use of this examination[3,7]
Clinical dentists are working to prevent dental and oral diseases that can lead to tooth anomalies or more severe changes within the oral mucosa, where panoramic radiographs are presented as the main exam
Summary
Panoramic radiography is an extraoral procedure of simple execution, in which it visualizes the whole maxillo-mandibular complex[1,2,3] This technique uses an external image receptor that moves in synchronism around the head of the individual, significantly reducing the discomfort of the radiographic examination to the patient, in addition to subjecting the patient to minimal ionizing exposure[4]. DDA is a multifactorial disease change caused by genetic, epigenetic, and environmental factors. The objective of our study was to characterize the epidemiological profile through a large cohort of non-syndromic patients and in a wide range of ages, through a survey of panoramic radiographs correlating developmental dental anomalies and post-eruption changes and associating them with gender and location
