[Tooth retention in the anterior region]

Bibliography was researched in pursuit of an improved classification of retained canine teeth that may, ideally, prove to be simpler, easy to apply in any individual case, and uncomplicated to remember. Desirably, such classification would allow establishing the location of each retention in the maxilla, mandible, or both, and its relationship with adjacent structures. Additionally, a proposal was put forth for a retained canine teeth classification that may clearly and simply outline the retention, be easily understood and remembered, and may also apply to retained dentary organs with some similarity to canines as to their shape and root number.
