Dental agenesis is a common developmental anomaly that affects approximately 20% of the population and results in a reduction of the number of teeth present in the oral cavity.Very rarely, more than one anomaly caused due to varying local etiological factors are seen in one patient.The aetiology of dental agenesis may be attributed to either environmental or genetic causes.Environmental factors include, different types of traumas to the alveolar processes, rubella, radiotherapy, use of chemical substances or drugs, as thalidomide and chemotherapy and disturbances in the innervations of cent dyyni the jaw.The absence of teeth is a clinical and public health problem, since the patients in these conditions may present several signs and symptoms as masticatory problems, malocclusion, problems in articulating words, and also the aesthetics may be here compromised.
These complications may affect self-esteem, behaviour pattern, and social life of these patients.Regarding the diagnosis of oligodontia, it is normally based on radiographic evidence and routine clinical examination, detecting absence of teeth or delayed eruption of them.The panoramic radiography is the most indicated for the diagnosis and study of agenesis, due to this radiographic exam register all maxilla-mandibular regions as well as the development of the tooth germ of the patient with minimal radiation.The motive of this article is to report a case of multiple local etiological factors as the cause of malocclusion and the interceptive management of the case, to prevent aesthetic, functional and psychological problems.
