N, total number of odontogenic cysts – frequencies are proportions of odontogenic cysts only; NI, not included – proportions only given for the three main cyst types; NR, not reported.
a Data for radicular cyst includes residual cysts.
b Data for dentigerous cyst includes eruption cysts.
Among other cyst types, Jones and Franklin (2006a ) found that the most common were mucoceles (3.9%; n = 1720), while all other cysts were rare (less than 1.0%).
These data show that cysts are relatively common and that the most commonly encountered are the radicular cyst, dentigerous cyst, and mucoceles. They also suggest that when a periapical radiolucency is seen, about 50% will be a radicular cyst and 50% will be a periapical granuloma. Details of the frequency and incidence of each cyst type are illustrated and discussed in the following chapters.
