“…Contrary to the findings from our study, in the studies of Mishra et al ( 18 ), Kaur et al ( 19 ) and Upadhyaya et al ( 20 ), M3 agenesis was found more frequently in males. The female predilection was similar to that reported by Sandhu and Kaur ( 21 ) and Sujon et al ( 16 ).…”

“…Celikoglu et al ( 27) and Mishra et al (18) reported that the missing of all M3 teeth was more frequently found than the presence of M3 teeth, similar to the findings of this study. In the study of Mishra et al (18), upper right M3 agenesis had the highest prevalence while lower left M3 agenesis had the lowest prevalence. But, in this study, lower right M3 agenesis had the highest prevalence.…”

“…It can be said that these rates were higher than those of this study. In the study of Mishra et al ( 18 ), there were higher results compared to our study. It was reported that upper right, lower right, upper left and lower left M3 agenesis was 57.8%, 64.1%, 62.5% and 68.1%, respectively.…”

“…There was no significant relationship between hypodontia and missing right (18,48), left (28,38), maxillary(18,28) M3 teeth (p>0.05). However, we found that hypodontia was significantly higher in patients with missing mandibular (38,48) M3 teeth (p=0.001) (Table 3).…”

“…Hypodontia was detected in 37 (24.3%) pa- tients and oligodontia was detected in 3 (2%) patients. We didn't find a significant relationship between oligodontia and missing individual (18,28,38,48), maxillary (18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28), mandibular (38)(39)(40)(41)(42)(43)(44)(45)(46)(47)(48), right or left (28)(29)(30)(31)(32)(33)(34)(35)(36)(37)(38) M3 teeth (p>0.05).…”

Purpose: To evaluate the association between third molar (M3) agenesis and hypodontia and oligodontia in pediatric patients by using panoramic radiography. Materials and methods: Panoramic radiographs of 1,471 patients (899 females; 572 males) and 5,884 teeth were retrospectively evaluated. The age and gender of the patients were recorded. Patients ages 9-15 years old were included in the study. The mean age was 12.76. The agenesis of M3 teeth and the relationship between M3 agenesis and hypodontia and oligodontia were recorded according to findings from the upper and lower jaw, in both the right and left locations, along with the number of M3 with agenesis. Data were analyzed using chi-square and McNemar tests (p<0.05). Results: A total of 1,319 (89.7%) patients had all M3 teeth present in the mouth, while the other 152 (10.3%) had congenital agenesis in one or more teeth. The number of teeth in which M3 agenesis was seen, in order of the number of missing M3 teeth, the percentages were 2.6% for one, 2.4% for two, 1.0% for three and 4.3% for four missing teeth.Hypodontia was detected in 37 patients and oligodontia was detected in 3 patients. Conclusion: The prevalence of M3 agenesis varies from one population to another. Two of the dental anomalies associated with M3 agenesis are hypodontia and oligodontia. In this study, M3 agenesis varied in terms of region and gender; hypodontia was also significantly higher in patients with missing mandibular M3.

Introducción: la agenesia de terceros molares es una evidencia de la evolución de la especie humana, se calcula que en el futuro la formula dentaria será de 28 dientes, con la consiguiente desaparición de los terceros molares. Objetivo: determinar la frecuencia de agenesia de terceros molares a nivel general y según sexo, grupo etario, cuadrante. Métodos: se realizó un estudio descriptivo, transversal y retrospectivo en historias clínicas con radiografías panorámicas de pacientes atendidos en consultorios odontológicos de la ciudad de Chiclayo – Perú, entre los años 2018 – 2020. La población fue de 422 historias clínicas y la muestra fue 109 historias. Los resultados fueron mostrados en tablas y gráficos y se utilizaron porcentajes. Resultados: La frecuencia de agenesia fue 36.7%. En el sexo masculino fue de 90% frente al 10% de sexo femenino. En el grupo de 14 a 20 años se registró mas agenesia con un 77.5%. El diente que tuvo mas agenesia fue el 3.8 con 37.5%. Conclusiones: al igual que otros estudios, se observa agenesia de terceros molares (36.7%), siendo un aspecto a considerar respecto a la evolución de la especia humana.
