Report of a case with 19 supernumerary teeth in a non-syndromic patient.

Supernumerary teeth occur frequently in human dentition, but presence of multiple supernumerary teeth in patients without any associated syndrome or systemic disorder is a rare phenomenon. Presence of supernumerary teeth in itself is not a problem and may not require removal in all cases but in certain conditions, they may be associated with several clinical complications and require removal. Here, we present a 14 year old female who complained of non emergence of permanent teeth.

Primary cN0 lip squamous cell carcinoma and elective neck dissection: Systematic review and meta-analysis.
