This type of treatment is more ideal for small cysts. A cystostomy is recommended for larger cysts that compromise important adjacent anatomy. The cyst is tamponaded to allow for the cyst contents to escape the bone. Over time, the cyst decreases in size and bone regenerates in the cavity space. Marsupialization could also be performed, which involves suturing the edges of the gingiva surrounding the cyst to remain open. The cyst then drains its contents and heal without being prematurely closed. The end result is the same as the cystostomy, bone regeneration. For both a cystostomy and marsupialization, root resectioning may also be required in cases where root resorption has occurred. Epidemiology
Periapical cysts comprise approximately 75% of the types of cysts found in the oral region. The ratio of individuals diagnosed with periapical cysts is 3:2 male to female, as well as individuals between 20 and 60 years old. Periapical cysts occur worldwide. Types of Periapical cysts:
Apical: 70%
Lateral: 20%
Residual: 10%

In a marathon, several percent of runners may be affected. Wearing footwear which fits helps prevent runners toe.If the shoe is too loose on the midfoot, the foot can slide forwards in the shoe, especially when going downhill. This may jam the toes into the end of the toebox. If the foot is sliding forwards because the shoe is too loose around the midfoot, it may be restrained by lacing the shoe carefully, or placing bulky padding between the tongue and the lacing, or by wrapping a strap in a figure-eight around the foot and ankle (image). : 86–87, 128, 142  Excessively tight or uneven fit around the midfoot may, however, cause tendon problems. : 125 Separately, if there is not enough space around the toes, the toes will also hit the toebox repeatedly. Feet become longer and wider when weight is put on them, because the arches flatten, and the toes also splay and bend. : p15, 18, 72–73  At the end of a long journey on foot, the arches flatten, the metatarsals spread, and the foot swells more than after a short one. : 52  The toes also need vertical space; a toe cap which is low enough to press on the top of the toe may also cause bruising under the nail, especially if the toe cap is stiff. If the toebox is pointed, the toes may be wedged forwards into the area with inadequate height. : 52–53, 135 Toenails which protrude unevenly may concentrate force on the toenail; properly-cut nails are therefore also important.Some susceptible runners may also have Mortons toe.
