Genetics and presence of non-syndromic supernumerary teeth: A mystery case report and review of literature
A 28-year-old male reported to our OPD with chief complaint of pain in mandibular left first molar. Patient also gave history of extraction of mandibular right first molar 5 years back. The medical history was non-contributory. The patient also gave familial history of presence of extra teeth in his grandfather, father, and younger brother. On clinical examination, deep proximal caries were seen with mandibular left first molar. The maxillary left canine was unerupted. Patient also showed presence of 3 supernumerary teeth; 2 in maxilla, between maxillary right canine and premolar and in place of maxillary left canine and 1 in mandible, in place of extracted right first molar [Figure and ]. An intra-oral periapical radiograph with respect of mandibular left first molar revealed presence of premolar like tooth in the periapical region of mandibular left second premolar. Thus, the patient was subjected to panoramic radiograph, which revealed total of 8 supernumerary teeth along with impacted maxillary left canine []. Two supernumerary teeth resembling premolars were present in each of the 4 quadrants. Patient was educated about the presence of impacted supernumeraries and then referred to department of conservative dentistry for further treatment.\nOn the next visit, his father and younger brother were also asked to report for clinical examination. Patient's grandfather was dead, hence we could not get any clinical records, except for the familial history of extra teeth. The father, 60-year-old male, on clinical examination, showed presence of 4 supernumerary teeth; 1 in maxilla and 3 in mandible. The OPG showed presence of total 5 supernumerary teeth. Four supernumerary teeth were present in mandible and 2 in maxilla [].\nThe younger brother, who was 20-year-old, showed presence of mesiodens clinically. The intra-oral periapical radiograph showed presence of second inverted mesiodens, which was impacted []. However, the OPG did not show any other supernumerary teeth.\nAll 3 patients were investigated for presence of any other anomaly, but no significant findings were noted. Hence, a diagnosis of familial non-syndromal hyperdontia was made.
