Influence of pulp necrosis and periapical inflammation of primary teeth on their permanent successors

History of the Dental Trauma Guide

“…In several experiments, the effect of treatment procedures such as extraction or awaiting spontaneous eruption was examined (72,75). Furthermore, the detrimental effects on the permanent successor caused by chronic inflammation in primary teeth because of an untreated pulp necrosis were analysed (77).…”

“…In the early 1970s, a unique opportunity for doing experimental dental traumatology occurred, when the senior author was able to do research on monkeys used at the Danish Serum Institute; these animals were used as kidney donors for polio vaccine production. The experiments conducted on these monkeys resulted in 64 experimental dental trauma studies including some in vitro studies (71–135).…”

Diagnosis Dilemmas in Vital Pulp Therapy: Treatment for the Toothache Is Changing, Especially in Young, Immature Teeth

“…Schroder et al (25) reported development of periapical osteitis in 82% of gray discolorations within 1 month. Andreasen and Riis (27) have shown that pulp necrosis and periapical inflammation of 6 weeks' duration did not lead to developmental disturbances of permanent teeth. Thus, when diagnosis cannot be established, it is justifiable to wait for further developments.…”

Fatores relacionados à ocorrência de necrose pulpar em incisivos decíduos traumatizados

“…A presença de infecção na região periapical do dente decíduo como resultado da necrose pulpar pode se espalhar e envolver o folículo do germe do dente permanente em desenvolvimento, levando a mudanças no epitélio do esmalte e na formação dentinária (Andreasen;Riis, 1978;Croll;Pascon;Langeland, 1987). Esse processo gera distúrbios na odontogênese, resultando na presença de hipoplasias e hipomineralizações e em casos mais severos na paralisação da formação do germe do dente permanente sucessor (Brook;Winter, 1975).…”
