RESUMO

Soft tissue deficiency in a tooth extraction site in the aesthetic area is a common and challenging clinical situation. This case report demonstrates the successful treatment of extensive gingival recession and buccal bone dehiscence associated with a hopeless tooth. Initially, a connective tissue graft was used to cover the root and thicken the soft tissue. After 2 months, the tooth was extracted, an implant was immediately placed, and a temporary restoration was installed. After 3 months, the soft tissue exhibited a natural and harmonious architecture. A custom zirconia abutment and crown were then fabricated and placed. At the 4-year follow-up, the peri-implant tissue displayed satisfactory aesthetics, with a well-structured buccal bone plate and healthy peri-implant indicators. This two-stage approach, addressing gingival recession first and proceeding with immediate implant placement after soft tissue healing, proved to be a safe and effective method with stable long-term results.

RESUMO

This case report addresses the treatment of excessive gingival display (EGD) in the context of maxillary asymmetry, zenith irregularities, and occlusal plane inclination. Digital planning was pivotal in formulating a precise treatment strategy by incorporating facial photographs, digital models, and cone-beam computed tomography data. Parameters, including occlusal plane inclination, teeth position, and lip-to-gingival margin relationships, were considered to ensure treatment alignment with the patient's facial characteristics. Notably, during the planning phase, it was evident that the conventional approach using the cementoenamel junction as the apical limit for incisions would result in asymmetry. Consequently, the gingival margin position was defined in accordance with facial and lip features. The chosen treatment, flapless crown lengthening, was tailored to the patient's thin phenotype and guided by measurements derived from digital planning. Postsurgery, the patient experienced a swift and painless recovery. A harmonious smile with a stable gingival margin position was achieved at the 1-year follow-up, seamlessly complementing the patient's facial attributes. This case underscores the importance of personalized EGD treatment and the value of digital planning in enhancing diagnostic accuracy and precise treatment planning, ultimately facilitating optimal treatment strategies.

RESUMO

This study aimed to estimate the prevalence and extent of bleeding on probing and calculus in 12-year-old schoolchildren of Quito, Ecuador, and evaluate the associated factors. We conducted an epidemiological survey with a representative sample of 1,100 12-year-old schoolchildren from public schools in the urban area of Quito, Ecuador. We assessed the periodontal health using the Community Periodontal Index (CPI). The prevalence and extent of the periodontal condition was based on the presence of at least one site with bleeding on probing (BOP), and the presence of dental calculus was also evaluated. We used univariate and multiple multilevel Poisson regression analyses to verify the association between the independent variables and the number of sextants with BOP and calculus. The prevalence of BOP and calculus was 92% and 69.9%, respectively. The adjusted mean of the affected sextants was 4.3 and 2.2 for BOP and calculus, respectively. The mother's schooling and malocclusion were associated with the number of sextants with bleeding. The mother's schooling and dental caries experience were associated with calculus. Gingival bleeding and the presence of dental calculus are highly prevalent in 12-year-old schoolchildren from Quito. Gingival bleeding is associated with maternal education and malocclusion, and dental calculus is associated with maternal education and dental caries.

RESUMO

AIM: This investigation aimed to evaluate the 1-year survival of implants placed after staged lateral alveolar ridge augmentation using equine-derived collagenated xenogeneic bone blocks (CXBBs) or autogenous bone block (ABB). MATERIALS AND METHODS: Fifty patients who underwent lateral augmentation in a previous trial were included. The primary outcome measure was implant survival at the 1-year follow-up, and secondary outcomes included implant success, peri-implant clinical and volumetric parameters, pink aesthetic scores (PES) and patient-reported outcome measures. Data analysis involved Fisher's exact test, the Mann-Whitney U-test and the Wilcoxon signed-rank test. RESULTS: In this study, no late implant failures were observed. The cumulative survival rates were 78.6% for the CXBB group and 90.9% for the ABB group, with no difference between the groups. Similarly, the success rates were 53.6% and 63.6%, respectively, showing no significant difference. Peri-implant clinical and volumetric parameters indicated the presence of healthy peri-implant tissues surrounding implants placed in both CXBB- and ABB-augmented sites. PES were 8.5 and 11.0 for implants placed in CXBB- and ABB-augmented sites, respectively. Furthermore, patient satisfaction rates were high and similar between the groups. CONCLUSIONS: Dental implants placed in both CXBB- and ABB-augmented ridges demonstrated no statistically significant differences in clinical, volumetric and aesthetic outcomes, along with high patient satisfaction rates.

RESUMO

BACKGROUND AND OBJECTIVE: As elsewhere in the world, the prevalence of periodontitis in stages I-II is high in the Latin American population, this scenario emphasizes the need for identification of urgent needs for allocating adequate resources to provide diagnosis, prevention, and treatment of these diseases. The aim of this Delphi study was to predict the trends in periodontology/periodontics in the Latin American region by the year 2030. METHODS: A steering committee and an advisory group of experts in periodontology/periodontics were selected from 16 countries. An open questionnaire of 60 questions was validated and used following the Delphi methodology. RESULTS: Two hundred and twenty-five experts from Latin America answered the two rounds of the questionnaire. Moderate to strong consensus was reached on 45 questions (75%). The prediction was that the prevalence of gingivitis and periodontitis in stages I and II will be maintained, the importance of the link with systemic diseases will increase, and the impact of prevention and periodontal treatment will also increase, mainly in the private sector. There was a strong consensus that plastic and regenerative surgical procedures will increase, as well as the demand for training in the specialty of periodontology. CONCLUSIONS: The present study has provided relevant and useful information on predictions in periodontology/periodontics in Latin America, with important level of consensus among experts. It has been predicted that periodontitis will still be a highly prevalent disease, and its links with other medical conditions should demand more attention by health authorities to develop adequate prevention and management policies and strategies.

RESUMO

The Internet is a growing source of knowledge and can provide information about oral health. This ecological study aimed to characterize the interests in toothpaste among Google users from different countries. Our hypothesis was that there would be an increase in Google users' interest in information about toothpaste. This retrospective longitudinal ecological study analyzed the toothpaste-related interest of Google users from 10 countries between January 2004 and December 2020. The monthly variation in relative search volume (RSV) and the main related queries were determined using Google Trends. Autoregressive integrated moving average (ARIMA) forecasting models were built to establish the predictive RSV values for toothpaste for an additional 12 months. Autocorrelation plots and the generalized additive model (GAM) were used to diagnose trends and seasonality in RSV curves. Additionally, the influence of social isolation related to the outbreak of COVID-19 was analyzed. Although not detected by autocorrelation function (ACF) and partial autocorrelation function (PACF) analyses, the heuristic analysis showed an increase in the interest in toothpaste-related information in all countries, with a stable trend observed in the 12-month forecasts, except for the increases in the United Kingdom and South Africa. Also, GAM analyses demonstrated a non-significant monthly or quarterly seasonal influence on data. In addition, social isolation during the COVID-19 pandemic did not influence the online information-seeking behavior of Google Search users linked to this topic. We confirmed the hypothesis that the interest of Google Search users in information about toothpaste increased in all of the 10 assessed countries.

RESUMO

AIM: To compare, at different levels from the alveolar crest, the radiographic outcomes of equine-derived collagenated xenogeneic bone blocks (CXBB) and autogenous bone blocks (ABB) used for lateral alveolar ridge augmentation. MATERIALS AND METHODS: Sixty-four patients with tooth gaps in atrophic alveolar ridges with ≤4 mm were randomly assigned to lateral augmentation using CXBB or ABB. The lateral bone thickness (LBT) was measured 2, 4, 6, 8, and 10 mm below the alveolar crest using CBCT scans obtained before augmentation surgery and at 30 weeks, prior to implant placement. Statistical analysis was performed using Shapiro-Wilk, Fisher's exact, Mann-Whitney, and Wilcoxon signed-rank tests. RESULTS: Both CXBB and ABB resulted in significant total and buccal LBT gains at 2, 4, 6, 8, and 10 mm. LBT gains were similar between CXBB- and ABB-augmented sites, except for greater buccal LBT gains at 8 mm at CXBB-augmented sites. While ABB-augmented sites gained vertical bone height, CXBB-treated sites suffered vertical bone loss (CXBB: -0.16 mm; ABB: 0.38 mm, p < .0009). CONCLUSIONS: CXBB and ABB were both associated with significant and similar LBT gains at 30 weeks.

RESUMO

Accumulated evidence has shown that the oral cavity may be an important reservoir for SARS-CoV-2. Some authors have suggested that the use of mouthrinses could reduce SARS-CoV-2 viral load in the saliva. Thus, the aim of this review was to synthesize evidence about the efficacy of mouthrinses in reducing the salivary viral load of SARS-CoV-2. 2. Nine randomized controlled trials (RCTs) have investigated the efficacy of different mouthrinses in reducing salivary SARS-CoV-2 loads. Various active ingredients have been tested in these trials: 0.5%,1% and 2% povidone-iodine, 0.2% and 0.12% chlorhexidine (CHX), 0.075% cetylpyridinium chloride (CPC), 0.075% CPC with Zinc lactate, 1% and 1.5% hydrogen peroxide (HP), 1.5% HP + 0.12% CHX and ß-cyclodextrin and citrox. The studies reported an intra-group reduction in the salivary levels of the virus, when compared with the baseline. However, the majority of these trials failed to demonstrate a significant inter-group difference between active groups and the control group relative to the decrease in salivary SARS-CoV-2 loads. Although promising, these results should be confirmed by larger trials.

RESUMO

OBJECTIVE: The aim of this study was to systematically analyze the influence of smoking on the incidence of peri-implantitis. MATERIALS AND METHODS: The search was performed in the National Library of Medicine (MEDLINE-PubMed), SCOPUS, EMBASE, and ISI Web of Science databases (finished on November 30, 2022). Systematic review and meta-analysis were conducted according to PRISMA statement. Prospective cohort studies that evaluate the incidence of peri-implantitis in smokers and non-smokers were included. Two authors independently searched for eligible studies, screened titles, and abstracts, did the full-text analysis, extracted data, and performed the risk-of-bias assessment. The results were summarized through random-effects meta-analyses. The GRADE method was used to determine the certainty of evidence. RESULTS: A total of 7 studies with 702 patients and 1959 implants were included for analysis. The meta-analysis revealed a significant difference between smokers and non-smokers for the risk of peri-implantitis in the implant-based (p < .0001) and patient-based analysis (p = .003). A strong association between smoking and the risk for peri-implantitis was verified at the implant level (RR: 2.04, 95% CI: 1.46-1.85) and the patient level (RR: 2.79, 95% CI: 1.42-5.50). CONCLUSIONS: Moderate certainty evidence suggests that smoking is associated with peri-implantitis compared to non-smoking at the patient and implant levels.
