RESUMO

AIM: To evaluate the influence of the abutment material (zirconia vs. titanium) on the long-term aesthetic and clinical outcomes of implant-supported restorations. MATERIALS AND METHODS: In 30 patients, a single implant-supported restoration with either a zirconia or a titanium abutment was placed in the anterior maxilla (incisors, canines, and bicuspids). Aesthetic (Implant Crown Aesthetic Index or ICAI), clinical, radiographic, and patient-centred outcomes were recorded at baseline (1 month after final restoration), 1 year, and 5 years of follow-up. This study was registered in ClinicalTrials.gov (NCT02315794). RESULTS: Twenty-five subjects completed the follow-up visits at 1 and 5 years. ICAI values showed statistically significant better aesthetic outcomes when zirconia abutments were used compared to titanium abutments. Between 1 and 5 years, the aesthetic sub-analysis of the crown component worsened but the mucosal sub-analysis improved. There were no significant changes in bone levels, but the plaque index, bleeding on probing, and probing depths worsened in both groups. CONCLUSIONS: At 5 years, standard zirconia abutments achieved better aesthetic outcomes, although with similar clinical behaviour.

RESUMO

OBJECTIVE: The objective of this study was to investigate the survival and biological and mechanical complications of one-piece and two-piece zirconia implants at five years of loading. MATERIALS AND METHODS: Consecutive patients receiving zirconia implants were studied, collecting data at five years of loading on their clinical history, peri-implant health status, mechanical complications, esthetic results, and patient related outcomes. RESULTS: The study included 18 patients with 29 implants. The survival rate was 86% in implant-based analysis and 78% in patient-based analysis. There were no cases of peri-implantitis, but mucositis was present in 53% of implants. A mean of 4.1 ± 0.81 mm was obtained for probing depth and 1.6 ± 0.9 mm for crestal bone loss (radiographic assessment). There were no implant fractures. Major (10%) and minor (10%) prosthesis complications were observed. The esthetic outcome was moderate to almost perfect, with a high level of patient satisfaction. No significant association was found between survival rate and the presence of mucositis around one- or two-piece implants or any other study variable. CONCLUSIONS: The survival rate is low for one- and two-piece zirconia implants. Both types of implants demonstrated a low mechanical complication rate. The incidence of periimplantitis is low but mucositis is present in 50%. Patient satisfaction related to esthetics and function is moderate to high. They represent a good option for patients requiring an alternative to titanium implants. CLINICAL RELEVANCE: Zirconia implants appear to be an alternative to the titanium option and may be indicated for patients requiring "metal-free" restorations.

RESUMO

BACKGROUND: Isthmoceles are described as complications associated with caesarean section (CS). Only symptomatic isthmoceles should be treated. The main symptoms are abnormal uterine bleeding (AUB) in the absence of any other causes, pelvic pain and secondary infertility. There are several techniques described for the correction of isthmoceles. Isthmoplasty can be performed by hysteroscopy, laparoscopy or vaginal surgery. The aim of this study was to assess the effectiveness of hysteroscopic surgical treatment of isthmoceles in women with associated symptoms such as pelvic pain and AUB. MATERIALS AND METHODS: A prospective case series study was performed; this study included all women with AUB, pelvic pain and ultrasonographic (US) diagnosis of isthmocele, who had undergone hysteroscopic correction between June 2014 and December 2017 in our Hospital. RESULTS: Thirty eight women underwent surgical hysteroscopy for correction of symptomatic isthmoceles. All patients presented AUB, 42.1% experienced pelvic pain and 28.9% had secondary infertility. US evaluation of isthmoceles was performed using 2D ultrasound. The residual myometrial thickness (RMT) above the isthmocele was measured in women who expected future pregnancy; if it was <2.5 mm the patient was not included in the study because the correction was performed laparoscopically. Follow-up was performed one and two months after the surgery. In all cases, pelvic pain was resolved one month after the surgery. AUB disappeared within the first month in 87.5% of patients and in the second month in 96.8% of subjects; however, one patient needed further surgery to alleviate her symptoms. Secondary infertility was assessed one year after surgical isthmoplasty. Seven women completed the first year of follow up, and three of them (42.8%) reported pregnancy after treatment between six and eight months after the surgery. CONCLUSION: Hysteroscopic correction of symptomatic isthmoceles may constitute a safe and effective technique for patients who present AUB and pelvic pain.

RESUMO

OBJECTIVE: The aim of this consensus meeting was to assess the influence of implant neck and abutment characteristics on peri-implant tissue health and stability. MATERIAL AND METHODS: Group and plenary discussions were based on two systematic reviews focusing on the effect of titanium implants with different collar designs/surface modifications and the abutment material on the stability of marginal bone levels (MBLs), peri-implant health, and survival rates. RESULTS: The changes in MBLs were not influenced by the abutment material and were also similar at one- and two-piece implants after one year of loading. Rough collar implants improved MBLs in comparison to machined collar implants. Additional modifications of the collar had no beneficial clinical effect on MBLs. Titanium abutments were associated with significantly higher increases in bleeding on probing when compared with zirconia abutments. CONCLUSION: MBLs are mainly influenced by the microstructure (i.e., rough surfaced) of the implant neck. Consensus statements and specific recommendations for future research were elaborated during the consensus meeting.

RESUMO

BACKGROUND: The gingival thickness seems to have an important role in different dental treatments. There are different methods of quantifying this thickness, but it is not known which of them can be the most effective. The objective to assess the accuracy of two different methods for gingival thickness measurement: the transgingival needle probing (TGNP) and the tension-free caliper (TFC) in an in vitro model, by comparing them with direct physical measurements (reference standard). MATERIAL AND METHODS: Gingival thickness (GT) was evaluated in 27 female pigs with four implant sites 1, 2 and 3mm from the gingival margin with three different methods: 1) transgingival needle probing 2) tension-free caliper and 3) Direct visualization after making a incision in the mucosa and measuring GT with a periodontal probe. Wilcoxon test for paired samples were used with a confident level of 95%. RESULTS: A total of 324 points were measured, 59% of the sites presented a thin biotype with DV, it was correctly assessed with the TGNP in 84% of the times and in 86% with the TFC. 41% of the sample presented thick biotype, 76% was the percentage measured with the TGNP and 0% of the sites evaluated with TFC resulted in this biotype. CONCLUSIONS: Transgingival needle probing constitutes an accurate method when measuring GT at different levels. Tension free caliper is not a good tool for assessing the gingival biotype as long as it is unable to predict thick biotype.

RESUMO

OBJECTIVES: The primary aim of this systematic review was to evaluate the available evidence on the effect of the abutment material on the stability and health of the peri-implant hard tissues. METHODS: A protocol was developed to answer the following focused question: "Which is the effect of the abutment material on stability and health of the peri-implant hard tissues?" Randomized controlled trials (RCTs), controlled clinical trials (CCTs) or prospective case series (CS) with at least 6 months of follow-up were included, and meta-analyses were performed to compare abutment materials vs. titanium and to evaluate the impact of various abutment materials on bone changes (primary outcome), probing depth, plaque levels and peri-implant mucosal inflammation. RESULTS: Twenty-nine publications from 33 investigations were included. Results from the meta-analyses demonstrated no significant differences between the different abutment materials when compared to titanium, in regard to the changes in marginal bone levels (MBLs) (n = 15; WMD = 0.034; 95% CI [-0.04, 0.10]; p < 0.339). The meta-analysis reported a significantly greater increase in bleeding on probing for titanium compared to zirconia abutments (n = 3; WMD = -26.96%; 95% CI [-45.00%, -8.92%]; p = 0.003). When evaluating the behaviour of each material different to titanium, there was a significant bone loss over time (n = 31; WMD = 0.261; 95% CI [0.18, 0.35]; p < 0.001) for all the individual materials except for titanium nitride. CONCLUSIONS: This systematic review has shown that the abutment material had minimal impact on marginal bone levels when compared to the standard titanium.

RESUMO

OBJECTIVES: This systematic review evaluated the evidence on the effect of the interventions aimed for lateral ridge augmentation (both simultaneously with implant placement or as a staged procedure) on peri-implant health or disease. METHODS: A protocol was developed to answer the following PICO question: "In patients with horizontal alveolar ridge deficiencies (population), what is the effect of lateral bone augmentation procedures (intervention and comparison) on peri-implant health (outcome)?" Included studies were randomised controlled trials or controlled clinical trials with a follow-up of at least 12 months after implant loading. Meta-analyses were performed whenever possible, including subgroup analysis based on follow-up. RESULTS: Twelve final publications from eight investigations were included. The results from the meta-analysis indicated that irrespective of the type of intervention, the inflammatory changes, based on bleeding on probing (%) were minimal, both at short- (n = 1; weighted mean difference [WMD] = -1.00; 95% CI [-14.04; 12.04]; p = .881) and long-term (n = 5; WMD = -5.63; 95% CI [-18.42; 7.16]; p = .881). When comparing different treatment modalities, no significant differences were observed (n = 6; WMD = -3.36; 95% CI [-12.49; 5.77]; p < .471). Similarly, changes in probing pocket depth and marginal bone levels were not significantly different among groups. The incidence of peri-implantitis was evaluated in three investigations and varied from 16% to 26% after a follow-up period of 6-8 years. CONCLUSIONS: The results from this systematic review and meta-analysis have shown that lateral ridge augmentation procedures can maintain peri-implant health over time with low mucosal inflammatory changes and a relatively small incidence of peri-implant bone loss.

RESUMO

OBJECTIVES: The purpose of this systematic review was to evaluate the impact of the abutment characteristics on peri-implant tissue health and to identify the most suitable material and surface characteristics. METHODS: A protocol was developed aimed to answer the following focused question: "Which is the effect of the modification of the abutment design in regard to the maintenance of the peri-implant soft tissue health?" Further subanalysis aimed to investigate the impact of the abutment material, macroscopic design, surface topography and surface manipulation. Randomised controlled trials (RCTs) with a follow-up of at least 6 months after implant loading were considered as inclusion criteria. Meta-analyses were performed whenever possible. RESULTS: Nineteen final publications from thirteen investigations were included. The results from the meta-analysis indicated that zirconia abutments (Zi) experienced less increase in BOP values over time [n = 3; WMD = -26.96; 95% CI (-45.00; -8.92); p = .003] and less plaque accumulation [n = 1; MD = -20.00; 95% CI (-41.47; 1.47); p = .068] when compared with titanium abutments (Ti). Bone loss was influenced by the method of abutment decontamination [n = 1; MD = -0.44; 95% CI (-0.65; -0.23); p < .001]. The rest of the studied outcomes did not show statistically significant differences. CONCLUSIONS: The macroscopic design, the surface topography and the manipulation of the implant abutment did not have a significant influence on peri-implant inflammation. In contrast, the abutment material demonstrated increased BOP values over time for Ti when compared to Zi abutments.

RESUMO

OBJECTIVES: The objectives of the present study is to determine the differences in peri-implant soft tissue color with the utilization of titanium, titanium gold-plated, white zirconia, Vita Classical (VC) A4-shaded zirconia, and fluorescent white zirconia abutments and to establish the influence of gingival thickness on the resulting color. METHODS: Four implants were contralaterally inserted in 19 fresh pig mandibles, and the color of the peri-implant mucosa with the different abutments was spectrophotometrically measured at 1-, 2-, and 3-mm height from the margin. RESULTS: At 1-mm height, titanium significantly differed from all zirconia abutments in lightness (L*), chroma along red axis (a*), and chroma along yellow-blue axis (b*) parameters. At 2 mm, all zirconia abutments differed from titanium in b* but only fluorescent zirconia in a*. At 3 mm, titanium differed from VC A4-shaded and fluorescent zirconia abutments in b*. At soft tissue thicknesses <1 and 1-2 mm, titanium differed from fluorescent zirconia in a* and b* and from VC A4-shaded zirconia in b*; at thickness >2 mm, no differences were found among abutments. All abutments differed from natural teeth in a* and b* at all heights and thicknesses except for fluorescent zirconia at thickness >2 mm. The Euclidean distance (ΔΕ) differed between titanium abutments and gold, VC A4, and fluorescent zirconia at <1- and 1-2-mm thicknesses. CONCLUSION: The natural gingival color was not reproduced with any abutment at gingival thicknesses <2 mm. The worst color match was with titanium abutments and the best with fluorescent zirconia, followed by VC A4-shaded zirconia. At gingival thicknesses >2 mm, no differences were detected among abutments. CLINICAL RELEVANCE: This study demonstrates that the type of abutment and the gingival thickness affect the resulting peri-implant gingival color.

RESUMO

The aim of this study was to test whether zirconia abutments exhibit the same clinical and esthetic outcomes as titanium abutments in single-tooth implant restorations in the esthetic area. The 24 treated patients were randomly assigned to a test (zirconia abutment) or control (titanium abutment) group. Objective evaluations were carried out using the Implant Crown Aesthetic Index (ICAI) and the Papilla Index (PI) at the 1-month and 12-month follow-up examinations after crown cementation. No significant differences, either in ICAI or in other periodontal or radiographic measurements, were observed. At 1 year, zirconia and titanium abutments exhibited the same esthetic outcomes.

RESUMO

STATEMENT OF PROBLEM: The reliability of spectrophotometric measurements of gingival color has not been tested. PURPOSE: The purpose of this study was to evaluate the repeatability and reproducibility of gingival color measurements with a digital spectrophotometer. Measurement error was estimated by determining the interrater agreement and by repeating measurements in different illumination environments with and without contact of the device with the gingiva. MATERIAL AND METHODS: Two trained examiners measured the gingival shade around 30 central incisors with a spectrophotometer with and without external illumination and with and without contact of the device with the gingiva. Color data obtained (CIELab color coordinates; L*, c*, h*, a*, b*) were analyzed with the intraclass correlation coefficient (ICC) and the Student t test for paired samples. RESULTS: Mean L*, c*, a*, and b* values differed significantly between measurements made with and without contact of the device with the tissue, but no difference was found in h* values. An ICC of >0.9 was obtained for interrater and intrarater agreements in all cases. Shade measurements did not differ between the presence and absence of stable ambient light. CONCLUSIONS: The repeatability and reproducibility of soft tissue shade measurements were almost perfect (ICC >0.9) under the examination conditions tested. The measurements were affected by pressure but not by ambient light.

RESUMO

AIM: To evaluate the aesthetic outcomes of zirconia versus titanium abutments for single tooth implant-supported crowns in the anterior maxilla. MATERIAL & METHODS: A parallel, double blind clinical trial was conducted at the Complutense University (Madrid), where 38 patients were recruited. After random allocation (via computer-generated permuted blocks), either zirconia (test) or titanium (control) abutments were placed. Intra- and inter-group differences in aesthetic (main outcome), clinical, radiographical, and patient-centred outcomes were evaluated at baseline (crown placement) and at 1-year follow-up. RESULTS: At 1 year, 25 of the 30 randomized patients were analysed (11 test and 14 control). Using the Implant Crown Aesthetic Index (ICAI), the scoring at baseline and 1-year were 7.9 and 7.6 for the test group and 10.6 and 11.3 for the control group, respectively. These differences were not statistically significant (sample size non-contrasted). Patient satisfaction was similarly high in both groups (visual analogue scale 8.5). Furthermore, no differences were observed in the clinical or radiographical outcomes. Two abutment fractures were registered in the test group. CONCLUSIONS: The use of zirconia abutments demonstrated a tendency towards better aesthetic outcomes although the differences were not statistically significant. However, more technical complications were noted with the use of zirconia abutments.

RESUMO

Apesar do consenso entre profissionais da saúde quanto ao reconhecimento dos sintomas depressivos na infância e na adolescência, seu diagnóstico ainda apresenta dificuldades. A literatura aponta o Inventário de Depressão Infantil (CDI) como um instrumento bastante utilizado para medir este construto. O presente estudo revisa os artigos científicos sobre o CDI, publicados em periódicos brasileiros no período de 2000 a 2010. Verificou-se que a maior parte das pesquisas foi conduzida a partir de 2005, no contexto escolar, com meninos e meninas e com o objetivo de verificar a associação de sintomas depressivos e variáveis psicossociais. As pesquisas reportaram bons índices de confiabilidade para o CDI, contudo, houve diferenças quanto à sua estrutura fatorial. Evidencia-se, assim, a necessidade de novos estudos que apontem novas evidências de validade do CDI como um instrumento útil para avaliar sintomas depressivos em crianças e adolescentes(AU)


Despite the consensus among health professionals regarding the recognition of depressive symptoms in childhood and adolescence, their diagnosis still presents difficulties. The literature points to the Children's Depression Inventory (CDI) as a widely used instrument to measure this construct. This article reviews the scientific articles about the CDI published in Brazilian journals from 2000 to 2010. It was found that most of the research studies were conducted after 2005, in school settings, with both boys and girls, and aimed to evaluate the association of depressive symptoms and psychosocial variables. The studies reported good reliability indices for the CDI, however, there were diffeerences regarding its factorial structure. New studies are necessary to prove the validity of the CDI as a useful measure to evaluate depressive symptoms in children and adolescents(AU)

RESUMO

AIM: To obtain an overall quantitative estimate of the association between pregnancy and gingival inflammation. MATERIAL AND METHODS: Medline and EMBASE databases were searched through August 2011. Prospective cohort or cross-sectional studies assessing the effect of pregnancy on gingival inflammation evaluated by the gingival index (GI) and/or bleeding on probing were included. Meta-analyses were performed if possible. RESULTS: Forty-four articles representing 33 studies (14 cohort and 19 cross-sectional) were included. Meta-analyses, performed whenever possible, revealed (1) a significantly lower GI in pregnant women in the first term compared with those in their second or third term of pregnancy; (2) a lower mean GI score in post-partum women compared with women in their second [WMD = 0.143; 95% CI (0.031; 0.255); p = 0.012] or third term [WMD = 0.256; 95% CI (0.151; 0.360); p < 0.001] of pregnancy, when considering cohort studies; (3) Non-pregnant women had lower mean GI values than women in their second or third term of pregnancy. Small changes in plaque levels were reported. CONCLUSION: Despite the limited number of studies included in the meta-analyses, the present systematic review confirms the existence of a significant increase in GI throughout pregnancy and between pregnant versus post-partum or non-pregnant women, without a concomitant increase in plaque levels.

RESUMO

AIMS: To identify predictor variables involved in exacerbated gingival inflammation associated with pregnancy. MATERIAL AND METHODS: In this cohort study, 48 pregnant and 28 non-pregnant women without periodontitis were included. The pregnant women were evaluated in the first, second and third trimester and at 3 months postpartum, whilst the non-pregnant women were evaluated twice, with a 6-month interval. At each visit, clinical [plaque index (PlI) and gingival index (GI)], hormonal (salivary progesterone and estradiol), immunological [gingival crevicular fluid interleukin-1ß, interleukin-6, tumour necrosis factor-α (TNF-α) and prostaglandin-E(2) ] and microbiological (periodontal pathogens culture) evaluations were performed. Statistical analysis was undertaken using exhaustive chi-square automatic interaction detection (exhaustive CHAID) to analyse the predictive value of the independent outcomes to develop pregnancy GI. RESULTS: PlI was the strongest predictor implicated in the GI throughout pregnancy and after delivery. During the second and third trimesters the presence of Porphyromonas gingivalis significantly contributed to the worsening of gingival inflammation. When compared with the non-pregnant group, significant differences were found in TNF-α amounts and concentrations and in the third trimester site-specific GI. CONCLUSIONS: Bacterial challenge to the gingival tissues, both quantitatively (PlI) and qualitatively (harbouring P. gingivalis) appears to affect the level of gingival inflammation observed during pregnancy.

RESUMO

AIM: To test whether exacerbated gingival inflammation in pregnancy is associated with increased salivary hormone levels and changes in gingival crevicular fluid (GCF) interleukin-1beta (IL-1beta) and prostaglandin-E2 (PGE2) levels. MATERIAL AND METHODS: In this cohort study, 48 pregnant women without periodontitis were evaluated in the first, second, and third trimesters and at 3 months postpartum. Twenty-eight non-periodontitis non-pregnant women were evaluated twice, with a 6-month interval. Plaque and gingival indices (PlI, GI), salivary progesterone and estradiol and GCF IL-1beta and PGE2 levels were determined. anova for repeated measures or Friedman's test were used for intragroup analyses. Inter-group comparisons were analysed with t-test or Mann-Whitney U-test. Correlations were evaluated with Pearson's and Spearman's test. RESULTS: Pregnant women showed an increase in GI (p<0.05) despite maintaining low PlI values. No changes in IL-1beta and PGE2 levels were observed during pregnancy. No significant correlation was found between the GI increase and salivary hormone levels. GI (p<0.05) and IL-1beta levels (p<0.001) were lower in non-pregnant than in pregnant women. CONCLUSIONS: This study confirms the presence of an exacerbated gingival inflammation during pregnancy, but this phenomenon could not be associated with an increase in progesterone or estradiol or with changes in PGE2 or IL-1beta.

RESUMO

AIM: To determine whether the exacerbated gingival inflammation that develops in pregnant women is related to a change in the subgingival biofilm induced by the increase in hormone levels during pregnancy. MATERIAL AND METHODS: This open cohort study included 48 pregnant and 28 non-pregnant women without periodontitis. Pregnant women were evaluated in the first, second and third trimester and at 3 months after delivery. Non-pregnant women were evaluated twice, with a 6-month interval, assessing microbiological, clinical and hormonal variables at each visit. Total anaerobic counts and frequency of detection and proportions were calculated. The Friedman test with the Bonferroni correction was used for intra-group comparisons and Mann-Whitney U-tests for inter-group assessment. Correlations were analysed by means of Spearman's rank correlation coefficient. RESULTS: Proportions of the subgingival periodontal pathogens did not differ throughout pregnancy, although significant differences were found for all the pathogens after delivery. Porphyromonas gingivalis-positive patients presented an increase in gingival inflammation (p<0.001) that was not related to plaque. Correlations were found between maternal hormone levels and P. gingivalis and Prevotella intermedia.

RESUMO

Este artigo aborda uma temática que atinge a todos: a infância e a adolescência marcadas pelas privações. O abandono, a negligência e o abuso físico, sexual e psicológico de crianças e de adolescentes são fatos reais e freqüentes na vida dos mesmos. A literatura psicanalítica sustenta a idéia de que as vivências de privação geram importantes seqüelas no desenvolvimento emocional, podendo marcar de forma peculiar a vida das pessoas para sempre. O percurso teórico realizado neste artigo aponta que crianças e adolescentes vitimizados apresentam dificuldades para investir em si mesmos e nos outros, o que os torna portadores de sintomas dificultadores da adaptação pessoal, social, escolar, institucional e familiar. É fundamental que eles possam elaborar as suas vivências passadas traumáticas, retomar o desenvolvimento de forma saudável e atualizar os seus potenciais (AU)
