ABSTRACT Objective: The purpose of the present in vitro study was to evaluate the efficiency of three different instruments in the root canals of artificial primary molars as well as the quality of the fillings. Methods: Sixty artificial primary molars were divided into three groups of 20 teeth. Each group was submitted to a different technique: Group 1 - conventional manual technique using Kerr files; Group 2 - manual technique with nickel-titanium files; Group 3 - NiTi rotary technique. The root canals were filled with calcium hydroxide paste. Aspects such as homogeneity of the fillings, taper and flowability of the preparations were considered comparatively to assess the quality of the instrumentations. The non-parametric Kruskal-Wallis and Mann-Whitney tests were used to compare the efficiency of the preparation of the root canal considering the preparation times of them. Results: All three techniques were equally effective at shaping the root canals of primary teeth. The working time was shorter with the rotary instrument (p=0.000). In the pairwise comparisons, working time was shorter with the rotary instrument compared to the manual techniques with steel files (p=0.000) and NiTi files (p=0.000). Comparing the manual techniques, the working time was shorter with NiTi files compared to steel files (p=0.011). Moreover, less variability in the preparation time was found when the rotary instrument was used. Conclusions: The mechanized rotary method led to a shorter operating time in comparison to the manual techniques and is therefore a preferable option for the preparation of the root canals of primary teeth.

ABSTRACT The Melkersson-Rosenthal syndrome constitutes a rare manifestation characterized by a triad of signs and symptoms: recurrent orofacial edema, fissured tongue, and recurrent facial paralysis. The difficulty in diagnosing Melkersson-Rosenthal syndrome is that orofacial edema is common to various diseases besides the lack of awareness of the syndrome by health professionals and the frequent metachronous manifestation of its symptomatology. The aim of this report is to present a classical case of Melkersson-Rosenthal syndrome and its clinical and therapeutic approach. A patient who sought for assistance at the Stomatology Clinic presented a synchronous manifestation of the triad: a left lip and cheek nonpitting edema accompanied by facial paralysis on the same side and fissured tongue. Melkersson-Rosenthal syndrome was diagnosed due to the presence of the triad of signs and symptoms after initially ruling out Crohn’s disease, Sarcoidosis, and tuberculosis due to a lack of intestinal or respiratory complaints and absence of other clinical evidence. The treatment administered was steroids, the most common treatment with a satisfied prognosis we found in the literature for Melkersson-Rosenthal syndrome patients. We recommend its implementation intralesional injections of betamethasone dipropionate as after four infiltrations the edema subsided by 80% with no further relapses within one-year follow-up.

ABSTRACT Objectives: To evaluate the translucency, contrast ratio and masking ability of a translucent zirconia with different thicknesses. Methods: Disc shaped specimens (n= 3) with 10 mm (Ø) x 1.5 mm, 1 mm and 0.7 mm (thickness) were manufactured simulating all-ceramic simplified restorations. Substrate discs (n= 2; Ø: 10 mm; thickness: 2 mm) were simulated with composite resin shades: A2 (positive control) and C4; and metal alloys: silver (Ni-Cr) and golden (Cu-Al). Optical properties of the 9 translucent zirconia specimens placed on the 3 different substrates were analyzed by a spectrophotometer. The color variation (ΔE00) between each ceramic structure over the positive control substrate (A2) and over the dark backgrounds (C4, silvery, golden) were obtained as to their ceramic masking ability and subjected to non-parametric Kruskal Wallis test (5%). The translucency parameter (TP00) and contrast ratio (CR) of the different thicknesses of the ceramic discs were also collected and analyzed by one-way ANOVA and the Tukey test (5%). Results: The translucent zirconia showed greater opacity in the thickness of 1.5 mm, although it was not statistically different between 0.7 and 1.0 mm. All dark backgrounds significantly affected the final color of the simplified restoration in all evaluated thicknesses. However, the increase in ceramic thickness showed a decrease in ΔE00 values for all substrates. Conclusion: The translucent zirconia was not able to mask the dark substrates, independent of the evaluated thickness.

ABSTRACT The CAD/CAM technology arose from the need to develop materials with better mechanical and optical properties that could be used for making monolithic restorations. Several materials have been used for milling indirect restorations in prefabricated blocks. Among them, lithium silicate reinforced with zirconia. Due to its recent introduction in the market, this case report aimed to present a detailed clinical protocol for the execution of a ceramic onlay of this material using CAD/CAM technology. A 57-year-old female patient sought care with extensive restoration in composite resin (BOMD) of tooth 15 maintained for almost two years. However, due to bruxism, constant dental tightening, the extension of the direct restoration and the need for improved esthetics, it was proposed to replace it with an indirect ceramic onlay restoration. Prophylaxis and choice of the color of the patient’s dental substrate were performed. Afterwards, the dental preparation was made and polished. Subsequently, the molding was made with addition silicone and the provisional restoration confectioned. Once the stone model was obtained, it was scanned and the ceramic onlay restoration was milled using CAD/CAM technology. Finally, the restoration was stained and cemented over the preparation. After 2 years, the restoration remained stable, with no evidence of color mismatch, marginal discoloration, marginal cleft, caries or fracture, proving the effectiveness of the treatment in this time interval. The correct indication of the ceramic material combined with the use of CAD/CAM technology facilitated the restorative process, restoring function and the esthetics desired by the patient.

ABSTRACT Objective: This study assessed whether the use of a silane coupling agent influence the bond strength of two universal adhesives to ceramic or resin CAD/CAM blocks. Methods: Forty-eight samples were obtained from each resin nano-ceramic hybrid block (RCBs) and lithium disilicate ceramic blocks (LD). Samples were treated with silane with MDP (Monobond - S-MDP), silane without MDP (Prosil - PS), and no silane application (Control - Ctr) followed by universal adhesive with silane (UAS) and without silane (UA) (n=8). Three polyurethane tubes (1.5 mm of internal diameter) were positioned in each sample treated surface and filled with a dual cured resin cement. Bond strength was assessed by microshear bond strength test and failure analysis was performed for all samples. Results: For the RCBs, UAS presented the highest bond strength values (p=0.004). Silane application was not significant in bond strength values (p=0.444). For LD, silane application was significant in bond strength values (p<0.001), but the adhesive was not (p=0.066). Failure analysis showed high prevalence of adhesive failures for both substrates. Conclusion: A silane-containing universal adhesive promoted the best bond strength results to the resin nano-ceramic hybrid block. For bonding to a glass-ceramic CAD/CAM material, additional silane (without MDP) application presented the best results.

ABSTRACT The “RichBlend” protocol was designed for facial filling and collagen biostimulation, by means of a mixture of calcium hydroxyapatite (CaHA), hyaluronic acid (AH) and autologous platelet concentrates. This work reports the case of a 53-year-old patient with cutaneous photoaging, loss of facial volume, multiple rhythms in the frontal and periorbital regions, also marked skin flaccidity, especially the eyelid. The treatment was done with botulinum toxin (65 U) and the “RichBlend” protocol. Venipuncture was performed and the blood was centrifuged to obtain i-PRF (injectable platelet-rich fibrin) and plasma gel. After venipuncture and blood centrifugation, i-PRF and plasma gel were obtained. CaHA (Radiesse®) was diluted: a) in saline solution + i-PRF (hyperdilution) for biostimulationof the lower third of the face; and b) in AH (Juvederm Ultraplus XC®) + plasma gel, for hydrolifting on the forehead and dark circles, malar and temples. Plasma gel was applied to the nasogenian grooves and then the entire face was properly massaged. The “RichBlend” protocol rejuvenated the patient, as it promoted filling, volumizing, collagen formation (biostimulation), reduction of flaccidity, in addition to skin whitening. Since HA and CaHA are high-cost products, their mixture with autologous platelet concentrates, in liquid or gel form, allows the use of a greater amount of filled and biostimulator material on the face, at a more affordable cost.

ABSTRACT Objective: This two-centre cross-sectional study aimed to evaluate whether xerostomia occurrence is associated with oral health-related quality of life (OHRQoL) in patients with end-stage renal disease (ESRD) after the adjustment for potential confounders. Methods: Oral examinations were performed by calibrated examiners for untreated dental caries, periodontitis and tooth loss in 180 adults with ESRD. The presence of xerostomia was determined using the global question “How often does your mouth feel dry?”. OHRQoL was evaluated by the simplified version of the Oral Health Impact Profile (OHIP14) questionnaire. Multivariate zero-inflated negative binomial regression analysis was used to calculate the incidence rate ratios (IRR) for the nonzero scores and odds ratios (OR) of having no impact in OHIP14 scores according to the presence of exposure. Results: In the adjusted model, xerostomia (IRR = 1.57; 95% CI: 1.12 to 2.20) was associated with poorer OHRQoL. The adjusted domain-specific analysis revealed that xerostomia occurrence significantly impacted the psychological disability and social disability, and the chance of having no impact was lower for the psychological discomfort domain (OR = 0.84; 95% CI: 0.12 to 0.98). Conclusion: Xerostomia exert an impact on OHRQoL in patients with ESRD, mainly in the psychological and social disabilities constructs.

ABSTRACT Photos of smiles posted on social media contain information on individuals’ anatomical and oral morphological characteristics, which can be important for ante and post-mortem human identification, during confrontation for forensic purposes. Objective: The study aimed to evaluate the feasibility of using smile photographs on social networks as a source of information for human forensic identification. Methods: The study sample consisted of forty individuals, randomly divided into four equal groups, two groups in Instagram (IG®) and two groups in Facebook (FB®). Standardized oral photographs of the anterior teeth of the participants, from three different angles (post-mortem photos) were taken using a Nikon® EOS 550D camera. Photos of smiles posted in FB and IG by the participants were also collected (ante-mortem photos). The analysis were carried out by 4 forensic experts, 18 dental professors, and 21 dental students. They compared simulated ante and post-mortem photos, to identify the alleged victims. Results: The correct identification score ranged from 28.6% (students) to 100% (forensic experts). The most frequently reported dental characteristics used for the identification were morphology of the anterior teeth, zenith, and gingival recessions. There was no statistically significant association between the rate of correct identification and the degree of difficulty reported during the analysis (p= 0,068), whereas there was also no association between this index and or the duration of the analysis (p=0,884). Conclusions: Therefore, the photographs of the smile posted on social media proved to be a database of dental information, and with potential to assist in identification with dental forensic purposes.

Standardized oral photographs of the anterior teeth of the participants, from three different angles (post-mortem photos) were taken using a Nikon® EOS 550D camera. Photos of smiles posted in FB and IG by the participants were also collected (ante-mortem photos). The analysis were carried out by 4 forensic experts, 18 dental professors, and 21 dental students. They compared simulated ante and post-mortem photos, to identify the alleged victims. Results: The correct identification score ranged from 28.6% (students) to 100% (forensic experts). The most frequently reported dental characteristics used for the identification were morphology of the anterior teeth, zenith, and gingival recessions. There was no statistically significant association between the rate of correct identification and the degree of difficulty reported during the analysis (p= 0,068), whereas there was also no association between this index and or the duration of the analysis (p=0,884). Conclusions: Therefore, the photographs of the smile posted on social media proved to be a database of dental information, and with potential to assist in identification with dental forensic purposes.","PeriodicalId":30069,"journal":{"name":"RGO Revista Gaucha de Odontologia","volume":"40 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91073165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ABSTRACT The use of antibiotic prophylaxis in the extraction of third molars is extremely controversial, raising several discussions about the most appropriate clinical protocol to avoid postoperative complications. To review the literature on the subject, describing the evidence for and against antibiotic prophylaxis to prevent surgical site infections in third molar extractions, besides establishing a prophylactic protocol and dosage regimen. A literature review was carried out analyzing scientific evidence from articles on the PubMed and Scielo platforms by searching for the descriptors “antibiotic therapy and infection in third molar extraction surgery”, “antimicrobial prophylaxis and infective endocarditis”, “antibiotic prophylaxis and adverse effects”, “antibiotic therapy in dentistry”, “surgical time and incidence of infections in extractions”, including original articles and double or triple blind randomized clinical trials, in Portuguese and English, published between 1980 and 2021, separated in chronological order. There is no consensus in the literature on the indication of antimicrobial prophylaxis, but factors as surgeon’s skill, time elapsed during the procedure and the patient’s general health status directly affect the incidence and severity of infections. Among all the literature analyzed for this study, it is possible to infer that the topic is still extremely questionable and, therefore, it is essential to conduct new experimental studies to obtain more conclusive data on the subject.

ABSTRACT Objective: ssess quantitatively and qualitatively tongue coating microbiota in ICU patients. Methods: Analytical observational study, convenience sample comprising 65 patients was included for medical report analysis and collection of general data, tongue coating assessment through visual inspection and microbiological sample collection for further laboratory analysis. The collection was performed by a single examiner using a sterile swab introduced and rubbing the posterior portion of the tongue close to the oropharynx. Results: Most patients (60%) belonged to the female sex, at mean age of 74.2 years. The main reasons for hospitalization were lung issues (26.2%) - prevailing associated comorbidities were diabetes (43.1%) and high blood pressure (66.2%). The mean length of stay in the ICU was one day. All patients presented tongue dorsum coating. There were Candida albicans (37%), Streptococcus parasanguinis (26.1%) and Streptococcus mitis (32.6%) in 1/3 of lingual extension. Streptococcus mitis (p=0,0265) was the most prevalent species. Conclusion: There was no significance between the amount of coating and number of observed species, although all assessed patients had presented coating. The most prevalent microorganisms were Candida albicans, Streptococcus parasanguinis and Streptococcus mitis.
