Healing pattern of the mucous membrane after tooth extraction in the maxillary sinus

Abstract

PurposeTo investigate the healing pattern of the mucous membrane after tooth extraction necessitated by periodontal disease in the maxillary sinus.MethodsOne hundred and three patients with 119 maxillary sinuses were investigated. Before implant placement, cone-beam computed tomography (CT) scanning was performed. The causes of extraction, the time elapsed since extraction, smoking, periodontal disease in adjacent teeth, and gender were recorded. In addition, the thickness of the mucous membrane of the maxillary sinus and the height of residual alveolar bone at the extracted area were calculated from CT images.ResultsThe thickness of the mucous membrane in the periodontal disease group (3.05±2.71 mm) was greater than that of the pulp disease group (1.92±1.78 mm) and the tooth fracture group (1.35±0.55 mm; P<0.05). The causes of extraction, the time elapsed since extraction, and gender had relationships with a thickening of the mucous membrane of the maxillary sinus (P<0.05). In contrast, the height of the residual alveolar bone at the extracted area, periodontal disease in adjacent teeth, and smoking did not show any relation to the thickening of the mucous membrane of the maxillary sinus.ConclusionsThe present study revealed distinct differences in healing patterns according to the causes of extraction in the maxillary sinus, especially periodontal disease, which resulted in more severe thickening of the mucous membrane.

Dental implants and grafting success remain high despite large variations in maxillary sinus mucosal thickening

“…Though this finding is consistent with some previously published studies [27, 28], other studies [21, 31] did report an association. These discrepant findings could be the result of different inclusion criteria in the study design.…”

“…This finding indicates that clinicians should expect some degree of mucosal thickening when performing sinus augmentation procedures in a previously periodontally involved site. This finding is consistent with several previously published studies [27–29]. Phothikhun et al [28] reported that sinuses with severe periodontal bone loss were three times more likely to have mucosal thickening.…”

“…Finally, 38 studies were eventually excluded for not meeting the strict inclusion criteria, and 31 studies that reported SMT were considered for qualitative analysis (Table 1). 12,13,15‐18,23‐47 Those studies reporting range or unclear data were excluded for the quantitative analysis (Fig. 1).…”

“…Overall, 19 studies 13,15,17,18,23‐37 fulfilled the inclusion criteria for quantitative assessment. Mean ± SE SMT was 1.17 ± 0.1 mm (95% confidence interval [CI] = 0.89 to 1.44).…”

“…Deve-se, portanto determinar corretamente a relação da membrana sinusal com as doenças bucais. (WALLACE, 1996;YOO et al, 2011 A correlação dos diferentes gêneros com a presença de septos, nessa amostra, mostrou uma relação estatisticamente significante para as mulheres, na presença de septos no teto do SM, onde o valor de p foi de 0,042. Não foi encontrado na literatura algum dado que pudesse reforçar esse achado.…”
