Multiple osteomas and supernumerary teeth are indicative of:

Marfan Syndrome
Gardner's Syndrome
Ehlers-Danlos Syndrome
Crouzon Syndrome

The correct answer is: Gardner's Syndrome

Multiple osteomas and supernumerary teeth are found in Gardner's Syndrome, which is a genetic condition that causes the growth of noncancerous tumors and extra teeth. The presence of these symptoms may also indicate other conditions, but only Gardner's Syndrome includes both multiple osteomas and supernumerary teeth as defining features. Marfan Syndrome and Ehlers-Danlos Syndrome, for example, are primarily known for their connective tissue abnormalities and do not typically present with these specific symptoms. Crouzon Syndrome, on the other hand, is a craniofacial disorder that is characterized by abnormal skull and facial bone growth, not by the presence of extra teeth. While it is important to consider the full range of symptoms when diagnosing a condition, in this case, the combination of multiple osteomas and supernumerary teeth points specifically to Gardner's Syndrome.
