Purpose:
The purpose of this study was to figure out the characteristics and occurrence of talon cusps in a sample of Turkish population.
Methods:
In this retrospective study, talon cusps in permanent dentition were evaluated on radiographs and intraoral photographs which were obtained from patients who were referred to Oral and Maxillofacial Radiology Department, Faculty of Dentistry, Adnan Menderes University, Aydın, Turkey between January 2013 and January 2014.
Results:
Talon cusps were observed in 365 of 4116 patients, with a frequency of 8.86 %. There were 208 (57 %) females and 157 (43 %) males with this variation. Maxillary canines were the most affected anterior teeth (40.83 %), followed by lateral incisors (39.60 %) and central incisors (19.55 %). Of the patients, 81 (22.19 %) had type I talon cusp with two periapical pathologies, 114 (31.23 %) had type II talon cusp with four periapical pathologies and 226 (61.91 %) had type III talon cusp with also four periapical pathologies.
Conclusions:
The occurrence of talon cusps was higher than other studies reported in the literature, with an exception of the study in Alaskan Eskimos. The most commonly detected type of talon cusp was type III (61.91 %), and dens invaginatus was the most frequent variation observed with talon cusps.

Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...
01:21Testing a Claim about Mean: Unknown Population SD
Estimating a population mean requires the samples to be approximately normally distributed. The data should be collected from the randomly selected samples having no sampling bias. There is no specific requirement for sample size. But if the sample size is less than 30, and we don't know the population standard deviation, a different approach is used;...
