Dental caries in HIV-infected children and adolescents: A systematic review with meta-analysis.

This study aimed to evaluate and compare the risk of dental caries in between human immunodeficiency virus (HIV)-infected and uninfected children and adolescents. An electronic search was performed on PubMed/MEDLINE, Web-of-Science, Scopus, LILACS, ProQuest, and ClinicalTrials.gov up to May 2022. The critical appraisal checklist developed by the Joanna Briggs Institute was used to evaluate the quality of the included studies. Meta-analysis was performed using the RevMan 5.4. Sixteen studies were included. A total of 3231 participants were evaluated, including 1701 and 1530 HIV-infected and uninfected children and adolescents, respectively. The meta-analysis revealed a higher risk of dental caries for primary dentitions in HIV-infected children and adolescents by decayed, missing, filled tooth (dmft) (SMD:0.34; p = 0.006) and decayed, missing, filled surface (dmfs) scores (SMD:0.37; p = 0.001). Similar results were observed for permanent dentition, with increased dental caries in HIV-infected children and adolescents with DMFT (SMD:0.32; p = 0.003) and DMFS (SMD:1.78; p < 0.0001) scores. Regarding the quality assessment, most of the included studies were moderate or good quality. However, the certainty of the evidence of the outcomes was very low. This systematic review and meta-analysis showed higher caries severity in permanent and deciduous teeth among HIV-infected children and adolescents.

Associated oral manifestations with HIV southeastern Brazilian patients on antiretroviral therapy

Abstract Objectives This study aimed to assess the prevalence of oral lesions in patients living with HIV infection and their association with CD4 count, viral load, and antiretroviral therapy in patients with HIV. Methods A cross-sectional study was conducted on a sample of 161 patients attending the… All the patients were examined for their oral lesions, current CD4 counts, type, and duration of the therapy. Data analyses were carried out using Chi-Square, Student T/Mann-Whitney, and logistic regression tests. Results Oral lesions were observed in 58.39% of patients with HIV. Periodontal disease with 78 (48.45%) or without mobility 79 (49.07%) was observed more frequently, followed by hyperpigmentation of oral mucosa 23 (14.29%), Linear Gingival Erythema (LGE) 15 (9.32%), candidiasis pseudomembranous 14 (8.70%). Oral Hairy Leukoplakia (OHL) was observed only in 3 (1.86%). A relationship between periodontal disease with dental mobility and smoking was found (p = 0.04), as well duration of treatment (p = 1.53e-3) and age (p = 0.02). Hyperpigmentation was related to race (p = 0.01) and smoking (p = 1.30e-6). CD4 count, CD4:CD8 ratio, viral load, or type of treatment were not associated with oral lesions. Logistic regression showed that the duration of treatment has a protective effect on the periodontal disease with dental mobility (OR = 0.28 [−2.27 to −0.25]; p-value = 0.03), independent of age or smoking. To hyperpigmentation, the best model included smoking (OR = 8.47 [1.18-3.10], p = 1.31e-5), without race or type and duration of treatment. Conclusion Among HIV patients undergoing antiretroviral treatment, oral lesions can be observed, predominantly periodontal disease. Pseudomembranous candidiasis and oral hairy leukoplakia were also observed. No relationship was found between associated oral manifestations in HIV patients and the start of the treatment, TCD4+ and TCD8+ cell count, TCD4:TCD8 ratio, or viral load. The data indicate that there is a protective effect of duration of treatment with relation to periodontal disease with mobility and that hyperpigmentation seems to be more related to smoking than type and duration of treatment.

Do dental implants placed in patients with osteoporosis have higher risks of failure and marginal bone loss compared to those in healthy patients? A systematic review with meta-analysis.

PURPOSE: This systematic review and meta-analysis aimed to compare the dental implant survival rate and marginal bone loss between patients with and without osteoporosis. MATERIALS AND METHODS: This systematic review was registered in PROSPERO (CRD42022356377). A systematic search was performed using five databases: MEDLINE/PubMed, Web of Science, Scopus, Embase, and ProQuest for articles published up to July 2022. Additional searches in ClinicalTrials.gov and the reference lists of included studies were performed. The eligibility criteria comprised observational studies with a direct comparison between patients with and without osteoporosis, with a minimum follow-up of 1 year and 10 implants placed in each group, which consider data analysis based on implant level, without restrictions on period or language of publication. The meta-analysis was performed using RevMan 5.4 program. Risk of bias analysis of the included studies was performed using the Newcastle-Ottawa scale (NOS). RESULTS: Twelve studies met the eligibility criteria, totaling 1132 patients with a mean age range from 54 to 76.6 years. Most of the included patients were women (73.6%). A total of 3505 implants were evaluated-983 in patients with osteoporosis and 2522 in patients without osteoporosis. The meta-analysis indicated no difference in implant survival rates between patients with and without osteoporosis (OR, 1.78; 95% confidence interval [CI], 0.86-3.70; P = 0.12). However, significant bone loss was observed around dental implants placed in patients with osteoporosis (SMD, 0.71 mm; 95% CI, 0.06-0.87 mm). The NOS indicated a low risk of bias in the studies included. However, the certainty of the evidence was classified as very low and low for implant survival rates and bone loss, respectively. CONCLUSION: According to the limitations of the present review, the data suggest that dental implants are a viable treatment option for the rehabilitation of patients with osteoporosis. However, clinical care by professionals is necessary to ensure the maintenance of peri-implant bone stability, as these patients may be susceptible to increased bone loss.

Mucoepidermoid carcinoma of the palate mimicking a pyogenic granuloma in a 30-year-old woman.

Mucoepidermoid carcinoma (MEC) is the most common salivary gland adenocarcinoma, more frequently affecting female patients in the fifth decade of life. When MEC arises in the minor salivary glands, the palate is the primary site. This case report describes an MEC on the palate of a 30-year-old woman. The lesion was initially treated as a pyogenic granuloma, but the final diagnosis based on histopathology was low-grade MEC. The patient was referred for cancer treatment, and no recurrence was observed during 3 years of follow-up. Some malignant tumors can mimic nonneoplastic reactive lesions clinically, which highlights the importance of biopsy and proper microscopic analysis of the resulting specimens.

Is the clinical performance of internal conical connection better than internal non-conical connection for implant-supported restorations? A systematic review with meta-analysis of randomized controlled trials.

PURPOSE: To evaluate bone loss, prosthodontics and biological complications, and implant survival rates of internal conical connections (ICC) compared with internal non-conical connection (INCC) implants. METHODS: The systematic review was registered on PROSPERO (CRD42021237170). Meta-analysis was performed using standardized mean difference (SMD) for bone loss and risk ratio (RR) for implant survival and complication rates. Risk of bias analysis was evaluated using RoB 2.0, whereas the GRADE tool was used to evaluate the certainty of evidence. A systematic search of the PubMed, Web of Science, Embase, Cochrane, and ProQuest databases was performed independently by two reviewers for articles published up to March 2022. The search criteria had no language or publication date restrictions. Handsearching analysis was performed in the reference list of potential articles. RESULTS: Twelve randomized clinical trials, including 678 patients and 1006 implants (ICC [n = 476]; INCC [n = 530]), were included. Meta-analysis revealed that ICC demonstrated a lower risk for marginal bone loss (SMD: -0.80 mm; p = 0.004) and prosthodontics complications (RR: 0.16; p = 0.01) than INCC. However, both internal connections demonstrated no significant difference in implant survival rates (RR: 0.54; p = 0.10) and biological complications (RR: 0.90; p = 0.82). The overall risk of bias revealed some concerns and a low risk of bias for most of the included studies. However, the certainty of evidence of outcomes was considered low to moderate. CONCLUSION: ICC may be considered a more favorable treatment option than INCC owing to greater preservation of peri-implant bone tissue and a lower probability of prosthodontics complications. However, well-conducted studies with long-term follow-up are warranted.

Impact of tilted implants for implant-supported fixed partial dentures: A systematic review with meta-analysis.

STATEMENT OF PROBLEM: The use of tilted implants has been considered a suitable option for completely edentulous patients. However, consensus on their clinical performance is lacking, specifically for partial rehabilitation. PURPOSE: The purpose of this systematic review and meta-analysis was to evaluate the marginal bone loss and implant survival rate of tilted implants compared with those of axial implants for implant-supported fixed partial dentures (ISFPDs). MATERIAL AND METHODS: A systematic search of the MEDLINE/PubMed, Web of Science, Embase, Cochrane, and ProQuest databases and reference lists for articles published until May 2022 was performed by 2 independent reviewers without language or publication date restrictions. A meta-analysis was performed using the RevMan version 5.4 program. Quality assessments were performed using the Newcastle-Ottawa scale. RESULTS: Nine studies were included, totaling 258 participants and 604 implants (269 tilted implants and 335 axial implants). No significant differences were found between the tilted and axial implants for the implant survival rate (P=.81; risk ratio: 1.14). However, higher marginal bone loss values were observed for tilted implants (P=.001; mean difference: 0.12 mm). No significant heterogeneity was observed in either analysis. CONCLUSIONS: No significant relationship was found between tilted and axial implants for ISFPD rehabilitation. However, tilted implants presented greater risks of marginal bone loss than axial implants.

Is a fiber post better than a metal post for the restoration of endodontically treated teeth? A systematic review and meta-analysis.

OBJECTIVE: To evaluate systematically the evidence about the failure rates of endodontically treated teeth (ETT) restored with intraradicular metal posts (MPs) or fiber posts (FPs). DATA: The review protocol was registered on PROSPERO (CRD42020189792). Eligibility criteria included randomized clinical trials (RCT) and prospective clinical trials (PCT) that compared the failures between FP and MP restorations for ETT. Meta-analyses were conducted for failure rates using fixed- and random-effects models. Subgroup and funnel plot analyses were performed. SOURCES: Four electronic databases (MEDLINE/PubMed, Web of Science, Scopus, and Cochrane Library), manual, and grey literature were screened by two researchers independently for articles published until November 2020 without language or time restrictions. For the analysis of the risk of bias, the Cochrane collaboration tool and ROBINS-I were used. The certainty of the evidence was evaluated using GRADE. STUDY SELECTION: Ten studies were included. A total of 704 participants with a mean age of 42.7 years with a total of 844 ETT were restored using 453 FPs and 391 MPs. The FPs presented similar failures to that with MPs (P=0.39; risk ratio [RR]:0.82; 95% confidence interval [CI]: 0.52 to 1.29). Subgroup analysis showed no significant differences between the FPs and MPs for the anterior region (P=0.60; RR:0.88; [CI]: 0.54 to 1.42), posterior region (P=0.52; RR:1.18; [CI]: 0.71 to 1.98), root fracture (P=0.44; RR:0.78; [CI]: 0.41 to 1.49), and debonding (P=0.56; RR:1.27; [CI]: 0.57 to 2.80). Additionally, FP showed similar failures compared with those of cast (P=0.36; RR:0.63; [CI]: 0.23 to 1.72) and prefabricated MPs (P=0.68; RR:0.90; [CI]: 0.54 to 1.50). The RCT and PCT studies revealed a low risk of bias for most of the domains. However, the certainty of evidence was considered low. CONCLUSION: No evidence of difference was observed for failure rates between FPs, and MPs, independent of region and different MPs used in ETT. However, further well-conducted clinical studies with high-quality evidence are encouraged. CLINICAL SIGNIFICANCE: Our results indicate that both retainer posts can be considered an adequate alternative in restoring ETT. Therefore, the choice of post (fiber or metal) could be based on dentist preference or individual characteristics of the patient as the failure rates for different posts are similar.
