Good overall stability and a small tooth loss rate were observed in this cohort of chronic periodontitis cases under SPT in private practice. Patient-based and tooth-based prognosis systems may be used to estimate the risk of tooth loss.

At present, there is insufficient evidence to answer the question on the differences in clinical outcome in terms of CBL between implants placed in sites with initial soft tissue thickness <2 mm and those with ≥2 mm. Further, well-designed controlled clinical studies are needed to analyze the effect of soft tissue thickness on the clinical outcomes of dental implants.

Attention should be placed on both horizontal and vertical FI in molars, owing to their association with tooth loss during SPT.

Aim: The aim of this analysis was to assess how different tooth-prognosis systems could predict tooth loss in a cohort of periodontitis patients followed up prospectively during supportive periodontal care (SPC).Materials and Methods: Clinical and radiographic data of 97 patients undergoing regular SPC for 5 years were used to assign tooth prognosis using four different systems

Objective: The health management of pregnant women in late pregnancy is difficult. Once vaginal infection occurs, adverse pregnancy outcomes will occur. The aim of this study was to explore the application value of biostatistics health assessment of matrix metalloproteinases (MMP) in vaginal secretions in late pregnant women with vaginal infection. Methods: A total of 120 late pregnant women with vaginal infection, including vulvovaginal candidiasis (WC) in 70 cases and bacterial vaginosis (BV) in 50 cases, were selected as the experimental group. Another 80 pregnant women with normal vaginal secretion in the same gestational week were randomly selected as the control group. Vaginal soft capsule of mycomycin was used in the treatment. The expression levels of MMP-8 and MMP-9 in vaginal secretions before and after treatment were detected by enzyme-linked immunosorbent assay (ELISA) and smear immunohistochemistry, Results: Both the ELISA and immunohistochemistry analysis showed that the levels of MMP-8 and MMP-9 in the vaginal secretion of experimental group were significantly increased than the data of control group (P < 0.05). After effective intervention, the levels of MMP-8 and MMP-9 were significantly lower than those before treatment (P < 0.05). Conclusion: The late pregnant women with vaginal infection was accompanied by the high level of MMP-8 and MMP-9 in vaginal secretions. Effective intervention will lead the reduction of MMP. Thus, the biostatistics health assessment of MMP is important for the late pregnant women with vaginal infection.
