“…Many studies have examined the frequency of M3 agenesis in Turkish populations. They reported frequencies of 23.3% (Kilinç et al, 2017), 23.8% (Kazanci et al, 2010), and 23.9% (Topkara & Sari, 2011). Their findings were very close to the M3 frequency that we found for all patients in the present study (24.9%).…”

“…M3s are important for the nutrition and survival of human ancestors, and these teeth more easily fit in early human jaws due to their longer dental arc length compared to anatomically modern Homo sapiens (Bergman, 1998; Kilinç et al, 2017; Silvestri Jr & Singh, 2003). The advent of agriculture and the beginning of industrialization led to a soft and refined diet that eliminated the need for large and powerful jaws and teeth in anatomically modern H. sapiens populations (Celikoglu et al, 2010).…”

“…In many studies, M3 agenesis has been examined according to sex (Rozkovcová, Marková, Lanik, & Zvárová, 2004; Sujon, Alam, & Rahman, 2016), orthodontic treatment (Celikoglu, Miloglu, & Kazanci, 2010), dietary habits, specific geographical regions(Goyal et al, 2016; Kazanci, Celikoglu, Miloglu, & Oktay, 2010), bilateral occurrence (Hirakata et al, 2016; Sanpei et al, 2016), a specific age group (Kaur et al, 2012; Kilinç, Akkemik, Candan, Evcil, & Ellidokuz, 2017), occurrence in the lower/upper jaw (Sujon et al, 2016), and which side of the jaw it occurs (Sujon et al, 2016).…”

Purpose Third molars (M3s) are the most common congenitally missing teeth. The aim of this study was to compare the frequency of M3 agenesis in two different age groups. Methods This study examined the panoramic radiographic images of 1036 patients. Two groups, each consisting of 518 patients, were arranged based on age ranges. The patients aged 12 to 19 years were in the first group and those 20 years and older were in the second group. The frequency of M3 agenesis was examined in both age groups. The distribution of M3 agenesis by sex and jaw was also recorded, along with the number of M3s affected by agenesis. Chi‐square tests were used to examine the relationships between categorical variables. Results M3 agenesis was observed in 29.3% and 20.5% in the first and second groups, respectively; the difference was statistically significant (P < .01). It was more common in female (27.3%) than in male patients (21.4%), and in the maxilla (11.2%) than in the mandible (5.8%), and the differences were statistically significant (P < .05). It was mostly observed forthemaxilla right M3 (18) (30.9%) and in the single quadrant of the jaws (9.7%). Conclusions The frequency of M3 agenesis was more common in patients aged 12 to 19 years than in those aged 20 years and older. Additionally, M3 agenesis was more common in females and in the maxilla.

“…Aunque sus resultados son variables debido a las diferentes características raciales de cada muestra y a la metodología empleada, la mayoría de ellos coincide en que la prevalencia de agenesia del G3M se encuentra alrededor del 25 al 30%. Por ejemplo, Killinc et al, (17) realizaron un estudio radiográfico retrospectivo en una muestra de 773 radiografías de pacientes de 12-18 años de edad, residentes en Turquía, en el que se concluyó que el 23.3% de la muestra presentaban agenesia de 1 a 4 gérmenes de terceros molares. Hegde et al, (18) estudió en la India una muestra de 700 niños, concluyendo que el 34.1% presentaban agenesia de terceros molares.…”

“…Resultados similares han sido reportados en la literatura. En un estudio se encontró una diferencia (p<0.001) en el porcentaje de agenesia de terceros molares en el maxilar (14.3%) comparado con la mandíbula (9.6%) (17). En otro estudio similar realizado por Ibarra (19), se informó que un grupo de 1046 pacientes de 13 a 14 años, fue más común observar agenesias en el arco maxilar que en la mandíbula.…”

In the human being, third molar is the tooth that exhibits more variants during its embryologic development, usually causing diverse anomalies and discomfort when erupting to the oral cavity. It has been pointed out that the prevalence of third molar agenesis is between 9 to 37%. The aim of the present comparative cross-sectional study was to radiographically assess the presence/absence of third molar germs (G3M) in a sample of pediatric patients of Mexican origin. A total of 513 panoramic radiographs were analyzed from patients attending the Pediatric Dentistry Postgraduate Program ( San Luis Potosí University, México), during the years 2011 to 2017. Inclusion criteria were patients between 7 and 18 years old, any gender; children with antecedents of a third molar extraction, previous orthodontic treatment, or with an associated congenital or systemic condition were excluded. Total prevalence G3M agenesis was calculated. Then, statistical comparisons of agenesia proportions per dental quadrant, gender, and age group were performed. 245 panoramic radiographs corresponded to the female gender, while 268 belonged to the male gender. The total prevalence of G3M agenesia was estimated in nearly 56%, and the 7-8 years old group exhibited the highest proportion; however, when this age group was excluded from the analysis, such prevalence decreased to 27.3%. Both mandibular quadrants showed higher proportions of G3M agenesia. There were no significant differences between genders. The total prevalence reported in the present study was found to be well above regarding the international parameters. It is quite possible that lack of radiographic visualization of G3M had been inaccurate in some cases due to the common absence of calcification traces from those teeth during early ages (7-8 years old). The adjusted analysis provided a prevalence value more in line with the recognized standards in the dental literature.

Abstract: As a result, while all M3 teeth were present in 76.71% of the population studied in the province of Izmir, agenesis of one or more than one M3 tooth was found in the other 23.29% of the patients studied.
