RÉSUMÉ

OBJECTIVES: To evaluate the potential of laser-microtextured abutments (LMAs) compared to machined abutments (MAs) in peri-implant clinical and radiographic outcomes. MATERIALS AND METHODS: Eligible studies consisted of randomized clinical trials (RCTs) retrieved from MEDLINE, Web of Science, Scopus, and Embase databases. The study adhered to the PRISMA statement, and the protocol was registered at the PROSPERO (registration number CRD42023443112). The risk of bias was evaluated according to version 2 of the Cochrane risk of bias tool (RoB 2). Meta-analyses were performed using random effect models. Afterward, the GRADE approach was used to determine the certainty of evidence. RESULTS: Four RCTs were included from a total of 2,876 studies. LMAs had lower peri-implant sulcus depth at 6-8 weeks (WMD: -0.69 mm; 95% CI: -0.97, -0.40; p = 0.15, I2 = 53%) and at one year (WMD: -0.75 mm; 95% CI: -1.41, -0.09; p = 0.09, I2 = 65%), but the certainty of evidence was low. In addition, the marginal bone loss favored the LMAs group (WMD: -0.29 mm; 95% CI: -0.36, -0.21; p = 0.69, I2 = 0%) with moderate evidence. There were fewer sites with bleeding on probing in the LMAs group (WMD: -1.10; 95% CI: -1.43, -0.77; p = 0.88, i2 = 0%). There was no statistical difference between groups for the modified gingival index and modified plaque index. Furthermore, all studies were classified as having some concerns risk of bias. CONCLUSIONS: There was low to moderate certainty evidence that LMAs can favor peri-implant clinical and radiographic parameters compared to MAs. CLINICAL RELEVANCE: Laser-microtextured abutments may benefit peri-implant clinical and radiographic outcomes.

RÉSUMÉ

OBJECTIVE: This study evaluated Temporomandibular Disorder (TMD) in individuals with Spinal Cord Injuries (SCI) compared to individuals without physical disabilities. DESIGN: Cross-sectional. SETTING: International Fair of Technologies in Rehabilitation and Accessibility (REATECH) and School of Dentistry at the University of São Paulo (USP), Brazil. PARTICIPANTS: In total, 19 patients with SCI and 19 patients without SCI (36.9 ± 11.4 years old) were examined by a calibrated examiner. METHODS: using the following parameters: cervical spine mobility, palpation of muscle groups of the head and neck, functional manipulation of the lateral and medial pterygoids, and joint palpation (Diagnostic Criteria). The pattern and amplitude of mandibular movements were determined during screening using the Helkimo index. STATISTICAL ANALYSES: Student's t-test, chi-square, Fisher's exact and Shapiro-Wilk test were used. RESULTS: The groups did not differ in the presence of noise, pain, temporomandibular joint palpation, locking, dislocation, jaw pain, muscle sensitivity, or in pain, mobility of the cervical spine and functional manipulation. With respect to the jaw mobility index, the groups differed in range of movement (P = 0.020) and maximum right lateral movement (P = 0.007), with the worst values in the SCI group. The groups also differed in relation to lateral flexion in cervical mobility, in which the group without SCI presented better results (P = 0.046). CONCLUSION: The Spinal Cord Injuries group showed higher levels of TMD in terms of range of movement, lateral flexion, and maximum right lateral movement, than the individuals without physical disabilities, demonstrating a clinical significance between cervical and mandibular disability in this group.

RÉSUMÉ

AIM: To compare tissue changes at implant sites previously treated with two biomaterials for alveolar ridge preservation (ARP) in the aesthetic zone, 1 year after restoration. MATERIALS AND METHODS: Sixty-six participants were treated with ARP using demineralized bovine bone mineral (DBBM) or DBBM +10% of collagen (DBBM-C), both covered with a collagen matrix (CM). Dental implants were placed, and definitive crowns were installed. Silicon impressions were taken before tooth extraction (T0), 2 weeks after crown insertion (T1) and 1 year after restoration (T2). Mid-facial mucosal level change (MLC), soft tissue thickness changes (TT), and marginal bone loss (MBL) were analysed using inter-group comparisons. RESULTS: Fifty-four participants were included in the analysis. The mid-facial level change between T0-T1 and T1-T2 showed no statistical difference between DBBM and DBBM-C. Between T0 and T1 for soft tissue thickness, DBBM performed significantly better at 3 and 5 mm below the mucosal margin. From T1 to T2, no significant differences between groups were found at any level for soft tissue thickness and MBL. CONCLUSION: At the aesthetic zone, advanced recession from tooth extraction to crown placement can be expected at sites treated with ARP regardless of biomaterial used. However, after crown insertion, tissue stability can be predicted.

RÉSUMÉ

Given the growing trend towards medical indications for continuous use of anticoagulants, the number of patients on these medications continues to rise. The management of patients on oral anticoagulants requiring oral surgical procedures has aroused much controversy. Changes in an anticoagulation regimen are associated with an increased risk of thromboembolism. However, it seems logical and advantageous for the patients' health if surgery could be performed without any change to the anticoagulation therapy. In dentistry, high-power lasers have been poorly explored in this field. The hemostatic properties of high-power lasers could be helpful during oral soft tissue surgeries in anticoagulated patients. The aim of this study was to compare bleeding time in anticoagulated rats after lingual frenectomy performed with a scalpel or diode laser with bleeding time in healthy animals. Twenty-four male Wistar rats were assigned to four groups (n = 6): (CS) Control-Scalpel Surgery; (AS) Anticoagulated-Scalpel Surgery; (CL) Control-Laser (diode laser 810 nm/1.5 W) Surgery; and (AL) Anticoagulated-Laser Surgery (diode laser 810 nm/1.5 W). Warfarin administration was used to induce anticoagulation. Blood was blotted every 30 seconds with filter paper until bleeding stopped to verify bleeding time. Two blinded researchers performed the surgeries and collected the bleeding time data. Diode laser surgery led to complete hemostasis in rats during and after lingual frenectomy. Zero bleeding was assessed during surgeries and after diode laser surgeries in anticoagulated rats. Laser-induced hemostasis offered an alternative solution to the controversial issue of intraoperative and postoperative bleeding control in patients on anticoagulation therapy.

RÉSUMÉ

Fraser syndrome (FS) is a rare recessive autosomal genetic disorder characterized by multisystemic malformations typically comprising cryptophthalmos, syndactyly, and renal defects. We report the case of a 16-year-old patient who exhibited facial asymmetry, short roots, hypodontia, and malocclusion. Oral rehabilitation included orthodontics, exodontia, and osseointegrated dental implants to improve the patient's self-esteem and eating function. We suggest short roots and hypodontia assessment in patients with FS.

RÉSUMÉ

The purpose of this cross-sectional study was to investigate the effect of different forms of periodontal diseases on Oral Health-Related Quality of Life (OHRQoL). Fifty-two patients with Aggressive Periodontitis (AP) or Chronic Periodontitis (CP) were included: nine patients with Localized Aggressive Periodontitis (LAP), thirty-three patients with Generalized Aggressive Periodontitis (GAP) and ten patients with Generalized Chronic Periodontitis (GCP). Oral Health Impact Profile questionnaires (OHIP-14) were distributed after a clinical examination that measured the following periodontal parameters: tooth loss, bleeding on probing (BoP), probing depth (PD), gingival recession (REC) and clinical attachment level (CAL). The global OHIP-14 score means were 10.6 for LAP, 16.5 for GAP, and 17.5 for GCP. A statistically significant difference (p < 0.01) was observed between the LAP group and the other two groups. There was significantly less bleeding and recession in the LAP group than in the patients with the generalized forms of periodontitis. LAP, GAP and GCP have an impact on patient quality of life when measured using the OHIP-14. Patients with GAP and GCP had poorer OHRQoL than LAP patients.

RÉSUMÉ

The development of a biodegradable material with antimicrobial properties for local applications is required in the prevention and treatment of infectious diseases. The objective of this study was to produce blends of poly-L-lactide acid (PLLA) synthetic polymer associated with several antimicrobials, as an alternative in the prevention and treatment of infections, as well as to evaluate its cytotoxicity, release of antimicrobials and inhibit bacteria growth. Blends of PLLA added with 20% Amoxicillin, Metronidazole, Clindamycin or Azithromicyn were used to produce Films (F) or Meshs (M) by casting and electrospinning methods, respectively. Standardized discs of the films and meshs were stored in buffer solutions (pH 5 or 7.4) and aliquots were analyzed by high performance chromatography (HPLC) during 168 hours. Cytotoxicity on human gingival fibroblasts was tested after 24, 48 and 72h by MTT reaction. The antimicrobial capacity was determined against P. gingivalis and S. pyogenes. The specimens were weighed after 3 and 6 months of storage for degradation analysis. SEM was performed to control interfaces and degradation. Antimicrobials presented a continuous and exponential drug release. Analysis showed that both M and F were able to inhibit S. pyogenes and P. gingivalis growth, indicating the release of active antimicrobial agents. The products were not toxic to the fibroblasts. Amoxicillin-film showed more degradation than PLLA at both pHs (p < 0.05), whereas Azithromycin-meshes were more degraded than PLLA at pH 7.4 (p < 0.05). PLLA association with antimicrobials is biocompatible and may represent a potential tool for the local delivery of antimicrobials.

RÉSUMÉ

OBJECTIVE: The aim of this study was to evaluate the need for antibiotic prescription in third molar surgery. STUDY DESIGN: A double-blind randomized study was carried out with 71 patients from CODONT (Dentistry Center of the Police of São Paulo). Amoxicillin, clindamycin, or no medication was administered for 7 days immediately after surgery. The participants evaluated the presence of pain, edema, interincisal distance (ID), presence of infection, Pell and Gregory classification, rescue analgesia, osteotomy, and odontosection. RESULTS: There was no difference (P < .05) between antibiotics and control over the surgery duration, dose, visual analog scale (VAS), ID, and edema, yet significant differences were seen over time for VAS, edema, and ID. CONCLUSIONS: Antibiotic prescription should not be indicated in all clinical conditions, yet it is necessary to correctly evaluate factors such as systemic condition of the patient, skill of the operator, and contamination of the surgical environment.

RÉSUMÉ

PURPOSE: The study aimed to assess electrocardiographic alterations during oral implant placement surgeries under local anesthesia (lidocaine chlorhydrate with epinephrine), using 15 mg of midazolam as an anxiolytic premedication. MATERIAL AND METHODS: The study randomly selected 20 patients, aged 21-50 years old, requiring bilateral mandibular dental implants. Each patient was assessed using placebo on one side and midazolam on the contralateral side, with random, double-blinded distribution. The electrocardiogram recorded 12 static leads every 2 min, while D2 derivations were recorded continuously. RESULTS: No statistically significant differences were observed between the placebo and midazolam when analyzing the morphological behavior of the electrocardiographic wave and the presence of arrhythmias during the experiment. However, under sedation, assessment of the behavior of electrocardiographic parameters during different stages of the procedure revealed statistically significant differences (P<0.05) for heart rate, P-wave amplitude and duration of the RR and QTc intervals. The arrhythmias detected were considered low risk for patients without systemic alterations and were observed in 53.3% of patients. The most frequently occurring alterations were tachycardia, bradycardia, supraventricular and ventricular extrasystoles and blocked atrial extrasystole, which were similar for both placebo and midazolam, with the greatest incidence during the initial, incision and bone drilling stages. CONCLUSION: The use of 15 mg of midazolam made no difference compared with the placebo. The use of 15 mg of midazolam did not show an advantage in the incidence of arrhythmias The anxiolytic premedication does not prevent myocardial arrhythmias in endosseous implant placement. The clinical significance of the arrhythmias may not represent serious risks.

RÉSUMÉ

This study evaluated fracture torque by torsion, in relation to the length and diameter of orthodontic mini-implants, to demonstrate their viability for clinical and experimental use based on the torque recommended by the manufacturers. The fractures at the moment of insertion, whose incidence in the literature is around 4%, are principally due to excessive force and the inability of the implant to resist rotational forces. Thirty orthodontic mini-implants of three commercial brands available in Brazil (Neodent 1.6 x 9 mm, Dentoflex 1.6 x 9 mm and Kopp 1.6 x 9 mm) were attached to a device made specifically for this research, leaving the mini-implants with sufficient stability. The miniimplants were submitted to torsion torque, using a digital torque wrench, until their breaking point. The values obtained with the test were submitted to analysis of variance and the Tukey test. The mean values of mini-implant ruptures were 26 N.cm for group A (Dentoflex), 25.4 N. cm for group B (Kopp) and 32.8 N.cm for group C (Neodent). From the Tukey test we could observe that the relationships between the means of the Dentoflex and Neodent groups, and between the Kopp and Neodent groups, were significant. Between the Dentoflex and Kopp groups, significance was nonexistent. All the values found in our research for fracture torque were higher than the limits recommended by the manufacturers for clinical use in orthodontics. The highest values were found in the Neodent group.

RÉSUMÉ

PURPOSE: The purpose of this study was to analyze electrocardiographic alterations during dental implant surgeries when local anesthetic agents were used. MATERIALS AND METHODS: Twenty implants were placed in 18 healthy patients. An electrocardiogram and Wincardio software were used to gather recordings from 12 static leads every 2 minutes, continuously record coronary artery (D2) derivations, and automatically measure the following electrocardiographic parameters: heart rate, duration and amplitude of the P wave, PR segment duration, ST segment deviation, QRS complex duration, and duration of the RR, QT, and corrected QT (QTc) intervals. RESULTS: Analysis of variance of the values obtained at the different stages showed significant differences (P<.05) for the heart rate and for the duration of the RR and QT intervals. The heart rate increased during the anesthesia, incision, and bone drilling stages, reaching a peak during drilling. Duration of the RR and QT intervals decreased during the incision and drilling stages. Among the electrocardiographic parameters individually assessed, several altered values were found for the duration of the P wave, the QRS complex, and the QT and QTc intervals. Sinusal tachycardia and bradycardia, sinusal arrhythmia, supraventricular extrasystole, ventricular extrasystole, and T-wave inversion were detected. CONCLUSION: Dental implant placement surgery may induce electrocardiographic alterations. The most frequently found arrhythmias were extrasystole and sinusal tachycardia. The anesthesia, incision, and bone drilling stages exhibited the highest heart rate values and the shortest durations of the RR and QT intervals.

RÉSUMÉ

This study compared behavioral and physiological changes during caries removal in children with Down syndrome when using a chemomechanical caries removal technique (Carisolv) and a conventional method of caries removal. Twenty children (ASA class 1) between 5 and 12 years of age participated in the study; 10 subjects had Down syndrome and 10 were healthy controls. The behavioral and physiological assessments were carried out during five stages of dental treatment: (1) 5 minutes before local anesthesia; (2) during local anesthesia; (3) during caries removal; (4) immediately after restoration; and (5) 5 minutes after the end of the treatment. The caries removal step resulted in the greatest behavioral and physiological changes. Except for oxygen saturation, statistically significant differences in heart rate (p<0.05) were recorded between children with Down syndrome and the control children.

RÉSUMÉ

A significância clínica dos achados eletrocardiográficos para pacientes sem histórico de doença cardiovascular é pequeno ou inexistente; porém, em pacientes com doenças cardiovasculares poderia justificar o uso de monitoração contínua, incluindo uso de eletrocardiograma, além de terapêutica comportamental ou medicamentosa para certos procedimentos odontológicos com níveis de estresse moderado a elevado. Este estudo teve como objetivo a avaliação das alterações eletrocardiográficas em cirurgias para a colocação de implantes dentários sob anestesia local com cloridrato de lidocaína 2% associado a epinefrina e uso de pré-medicação ansiolítica, com 15 mg de midazolam. O estudo foi realizado em 15 pacientes ASA I, com necessidade de implantes dentários, bilaterais em mandíbula. O estudo foi comparativo com placebo administrado aleatoriamente, duplo-cego uma hora antes do procedimento. O eletrocardiograma registrou 12 derivações estáticas a cada 2 minutos e o registro da derivação D2 de maneira contínua, avaliando a presença de arritmias durante o experimento. Não foram encontradas diferenças significantes entre os grupos estudados. Foram observadas arritmias em 53,3% dos pacientes. As arritmias encontradas foram a taquicardia e a bradicardia sinusal, as extra-sístoles supraventriculares, ventriculares e a extra-sístole atrial bloqueada, em ambos os grupos de maneira semelhante, com maior incidência nas fases início e perfuração. As arritmias encontradas foram consideradas de baixo risco para pacientes sem comprometimento sistêmico. Concluiu-se que o uso de 15 mg de midazolam não apresentou diferença quando comparado ao placebo. As arritmias mais freqüentes foram as extra-sístoles e as taquicardias sinusais.

RÉSUMÉ

A significância clínica dos achados eletrocardiográficos para pacientes sem histórico de doença cardiovascular é pequeno ou inexistente, porém em pacientes com doenças cardiovasculares poderia justificar o uso de monitoração contínua, incluindo o uso de eletrocardiograma além de terapêutica comportamental ou medicamentosa para certos procedimentos odontológicos com níveis de estresse moderado a elevado. Este estudo teve como objetivo a avaliação das alterações eletrocardiográficas em cirurgias para a colocação de implantes dentários sob anestesia local com cloridrato de lidocaína 2 por cento associado a epinefrina, com uso de pré-medicação ansiolítica com 15mg de midazolam. O estudo foi realizado em 15 pacientes ASA I, com necessidade de implantes dentários, bilaterais em mandíbula. O estudo foi comparativo com placebo administrado aleatoriamente, duplo cego 1 hora antes ao procedimento. O eletrocardiograma registrou 12 derivações estáticas a cada 2 minuto e o registro da derivação D2 de maneira contínua, avaliando o comportamento morfológico da onda eletrocardiográfica e a presença de arritmias durante o experimento. Não foram encontradas diferenças significantes entre os grupos estudados. Quando comparamos o comportamento dos parâmetros eletrocardiográficos durante as fases do procedimento, observamos diferenças estatísticas (p<0,01) para a freqüência cardíaca, amplitude da onda P e duração dos intervalos RR e QTc para o grupo com sedação. Foram observados arritmias em 53,3 por cento dos pacientes. As arritmias encontradas foram a taquicardia e a bradicardia sinusal, as extrasístoles supraventriculares, ventriculares e extrasístole atrial bloqueada, em ambos os grupos de maneira semelhante, com maior incidência nas fases início e ferfuração. As arritmias encontradas foram consideradas de baixo risco para pacientes sem comprometimento sistêmico. Conclui-se que o uso de 15mg de midazolam não apresentou diferença quando comparado ao placebo. A fase incisão apr...
