ABSTRACT
The aim of this study was to evaluate the effects of nonsurgical periodontal treatment on alveolar bone density (ABD) and bone height (BH) using direct digital radiography. Nineteen patients (mean age 36±7.3 years) with generalized chronic periodontitis were examined at baseline, 90 (90AT) and 180 (180AT) days after nonsurgical periodontal therapy. Radiographs were taken from two sites with specific characteristics 39 sites with probing pocket depth (PPD)≤3 mm and clinical attachment level (CAL)≤1 mm (shallow sites); and 62 sites with PPD≥5 mm and CAL≥3 mm (deep sites). The ABD was assessed considering the bone regions of interest at the alveolar bone crest (ROI I) and at the medullar bone (ROI II). The BH was assessed considering the distance from the alveolar bone crest to the cementoenamel junction. Mann-Whitney test was used for the overall demographic data, Wilcoxon test was used to compare the baseline, 90AT and 180AT data as well as to compare the groups and subgroups within the same evaluation period. The significance level was set at 5%. The deep sites showed a significant increase of ABD in ROI I at 90AT (p<0.007) and at 180AT (p<0.005). ABD decrease was seen in ROI II at 180AT (p<0.04) while BH reduced only in shallow sites at 90AT. In conclusion, an increase in ABD was observed in deep sites of patients with generalized chronic periodontitis. However, no significant change in alveolar BH was observed in these sites.
RESUMO
O objetivo desse estudo foi avaliar os efeitos do tratamento periodontal não cirúrgico na densidade do osso alveolar e na altura óssea alveolar usando radiografias digitais diretas. Dezenove pacientes (média de idade 36±7,3 anos) com pacientes com periodontite crônica generalizada foram examinados no tempo 0 e aos 90 (90AT) e 180 (180AT) dias após o tratamento periodontal não cirúrgico. Dois grupos de sítios foram radiografados, 39 com profundidade de bolsa a sondagem (PBS)≤3 mm e nível de inserção clínica (NIC)≤1 mm (sítios rasos) e 62 com PBS≥5 mm and NIC≥3 mm (sítios profundos). A densidade foi avaliada considerando as regiões ósseas de interesse na crista óssea alveolar (ROI I) e no osso medular (ROI II). A altura óssea compreendia a distância entre a crista óssea alveolar e a junção cemento-esmalte. Os sítios profundos mostraram um significante aumento na densidade óssea na ROI I tendo p<0,007 em 90AT e p<0,005 em 180AT. Uma redução na densidade óssea foi vista na ROI II 180AT (p<0,04) enquanto a altura óssea reduziu somente nos sítios rasos 90 AT. Como conclusão, um aumento na densidade foi observado na crista óssea alveolar de sítios profundos em pacientes com periodontite. No entanto, nenhuma alteração significante na altura óssea alveolar foi observada nesses sítios.
