Aim: This article is set on presenting various types of anodontia, the most frequent types found in a dental office and to bring awareness to parents and also the dentists on the signs of agenesis and its consequences in time. Material and method: for a year (1st September 2017 – 31th August 2018) various patients with different types and locations of anodontia were diagnosed correctly by an oral and radiological exam in a dental office. Results. Anodontia is found almost equally in both sexes without major differences between males and females. Real agenesis is most frequently found in the second premolars – study reports show that this is because of phylogenetic evolution. False agenesis is more frequent in the 3rd molars because they are most likely extracted. Third molars are usually extracted because they don’t have space to emerge on the maxilla or mandible or they emerge in a vicious position. Canine agenesis has a very low frequency. Conclusions: It is very important to do a thorough check-up and a correct case history followed by radiological investigations each time a suspicion of a possible anodontia exists. It can only be certainly diagnosed by having a full oral and radiological exam. Also a difference must be made between the real, false and pseudoanaodontia.
