Morphological Study of Root Surfaces in Teeth With Adult Periodontitis

Abstract

These data suggest that the spread of root resorption is associated with inflammation. This study also suggests that the capacity for repair of root resorption is diminished with greater severity of periodontitis.

Root Resorption in Chronic Periodontitis: A Morphometrical Study

“…These results are very similar to those observed by Crespo et al; 2 no teeth in group 1 presented affected dentin, just 5.88% of the teeth in group 2 (lower than Crespo et al 2 ), and 41.38% of teeth in group 3 (similar to Crespo et al 2 ). These results are very similar to those observed by Crespo et al; 2 no teeth in group 1 presented affected dentin, just 5.88% of the teeth in group 2 (lower than Crespo et al 2 ), and 41.38% of teeth in group 3 (similar to Crespo et al 2 ).…”

“…[2][3][4][5][6][7][14][15][16][17][18][19]21 In most of the teeth in the current study, only cementum was affected by resorptions, with resorption reaching the dentin in just 24.53%, compared to 30% reported by Henry and Weinmann. [2][3][4][5][6][7][14][15][16][17][18][19]21 In most of the teeth in the current study, only cementum was affected by resorptions, with resorption reaching the dentin in just 24.53%, compared to 30% reported by Henry and Weinmann.…”

“…This was a very important finding, since in none of the reviewed works [2][3][4][5][6][7][14][15][16][17][18][19] were the resorptions found on the gingival third the largest resorptions. In the current study, size of resorptions and severity of periodontitis are clearly associated.…”

Estudo ultra-estrutural e imunocitoquímico das reações do periodonto de molares de ratos submetidos a estímulos contínuos de vestibularização em tempos prolongados.

“…Quando uma força contínua é aplicada, é possível observar a reparação do cemento (FALTIN et al, 2001;CASA et al, 2006). Contudo, quando a reabsorção atinge a dentina, o cemento, na maioria das vezes, irá recobri-la com uma camada fina, não se recuperando a anatomia radicular inicial (ABELLEIRA et al, 1999). Devido a isso, são consideradas irreversíveis as reabsorções radiculares que atingem a dentina.…”

“…Outros trabalhos, no entanto, demonstram a reparação simultaneamente com o processo de reabsorção radicular durante a aplicação de forças contínuas (KUROL et al, 1997;CASA et al, 2006; JIMENEZ-PELLEGRIN e ARANA-CHAVEZ, 2007). As reabsorções radiculares ocorreram a partir do 15° dia e, em tempos prolongados, atingiram a dentina, e não foram totalmente reparadas, pois estas são consideradas irreversíveis (ABELLEIRA et al, 1999).…”
