Supernumerary roots.
Supernumerary roots are one of the development anomalies pertaining to the tooth root morphology. It is generally well known that the deciduous and permanent anterior teeth have a single root. Maxillary molars have three roots and mandibular molars have two roots. Pertaining to the premolars, except for the maxillary first premolars all other premolars have a single roots. These supernumerary roots may be due to the disturbances of the Hertwig's epithelial root sheath forming the root. Cases have been reported where in both the deciduous and permanent dentition exhibiting supernumerary roots. Here with we are presenting cases of supernumerary roots in permanent teeth involving maxillary third molars, mandibular first, second molars and mandibular second premolars.
