Сравнить частоту благоприятных исходов эндодонтического лечения опорных зубов под несъемные ортопедические конструкции у пациентов городского контингента (г.

В исследование включены 91 пациент городской группы (возраст 36,7 ± 5,0 лет, 187 опорных зубов) и 79 пациентов сельской группы (возраст 44,6 ± 9,5 лет, 176 опорных зубов). Распределение по числу зубов на пациента: городская группа – 1 зуб у 15 пациентов (16,5 %), 2 зуба у 56 (61,5 %), 3 зуба у 20 (22,0 %); сельская группа – 1 зуб у 2 (2,5 %), 2 зуба у 57 (72,2 %), 3 зуба у 20 (25,3 %).
