here kya ur answer!!
_______________

Maxillary sinus starts developing during intrauterine fetal life which continues to develop even after birth.

Size and shape of adult maxillary sinus are variable, and it may differ according to age of an individual, their size, and degree of pneumatization.

Maxillary sinus often expands between the molar roots and results in proximity between them. On radiograph, it seems that roots penetrate the sinus floor and protrude into maxillary antrum, but instead, it is the maxillary sinus that has extended around the roots of the tooth.
