RESUMO

Purpose: To assess the effect of rapid maxillary expansion (RME) on the inflammatory and stress response of patients undergoing orthodontic treatment. Methods: Eighty salivary samples were collected from patients (n=16) during RME at five moments: before the expander placement (T1); 25 minutes after its first activa- tion (T2); seven days after placement, shortly after the patient arrived at the dental clinic (T3); 25 minutes after the appliance activation on day seven (T4) and one month after the last activation of the appliance (T5). Cortisol and nitric oxide levels were evaluated using an immunoassay kit and the Griess method, respectively. Friedman and Wilcoxon tests were used for statistical analysis (P <0.05). Results: Participants' mean age was 11.5 years. There was a significant change in cortisol levels over the study period in the total sample (P<0.01), for the Haas appliance (P=0.01), female sex (P=0.01), younger children (P=0.01), presence of large overbite (P=0.02), presence of posterior crossbite (P =0.006), Class I type occlusion (P=0.02) and mesofacial facial type (P =0.02). Regarding nitric oxide, there was a significant change over the study period in those who wore the Haas appliance (P =0.04). For nitric oxide levels, T1 was significantly higher than T3, T4 and T5 (P <0.05) for those who wore a Haas appliance. Conclusion: The period anticipating the consultation at the waiting reception area was more stressful than the dental procedure in patients undergoing RME. This procedure did not cause alterations in salivary biomarkers related to inflammation.

RESUMO

OBJECTIVES: To evaluate the effect of analogues of cationic peptides on the viability and the expression of phenotypic and genotypic markers of dentin mineralization in MDPC-23 odontoblast-like cells. MATERIALS AND METHODS: Cells were exposed to serial dilutions of analogues of cationic peptides hBD-3-1CV and KR-12-a5 compared to peptide LL-37 and their viability was assessed by methyltetrazolium assay. Next, peptides (0.78-62.5 µg/mL) were applied on the MDPC-23 cells for evaluating the total protein (TP) production, alkaline phosphatase (ALP) activity and mineralized nodule deposition. Gene expression of mineralization markers (DSPP and DMP-1) was also determined by quantitative PCR. RESULTS: LL-37 and hBD-3-1CV treatment did not affect cellular viability at concentrations below 62.5 µg/mL. KR-12-a5 reduced cell viability above 31.25 µg/mL. TP production was similar for all groups compared with the control group, except by hBD-3-1CV (at 15.62 µg/mL). LL-37 (at 62.5 µg/mL) induced higher ALP activity than control and other experimental groups. LL-37 and hBD-3-1CV, at 62.5 µg/mL and KR-12-a5 at 31.25 µg/mL stimulated the highest deposition of mineralized nodule. Overall, no statistical differences were observed between the groups for DSPP-1 and DMP-1 expressions. CONCLUSIONS: LL-37 was the only peptide that induced both ALP activity and mineralized nodules deposition, without affecting cell viability. None of peptides tested induced the expression of DSPP or DMP-1, genes commonly involved in active dentin mineralization.

RESUMO

AIM: To evaluate the inflammatory response, biomineralization and production of osteocalcin (OCN), osteopontin (OPN), and bone sialoprotein (BSP) of a new root filling material for primary teeth (Bio-C Pulpecto) compared to MTA. DESIGN: Polyethylene tubes containing Bio-C Pulpecto, MTA, and empty tubes were implanted into the dorsal connective tissue. After 7, 15, 30, 60, and 90 days, the tubes with surrounding tissue were removed and histologically processed to be analysed using haematoxylin and eosin, von Kossa staining, or no staining for observation under polarized light and immunohistochemistry for the detection of OCN, OPN, and BSP. The Kruskal-Wallis test was used followed by Dunn's test. The significance level was set at 5%. RESULTS: The inflammatory response observed with MTA and Bio-C Pulpecto was more exacerbated until the 15th day and decreased from 30 days on. No significant difference was found between control, MTA, and Bio-C Pulpecto (P > 0.05). Bio-C Pulpecto and MTA showed positivity for von Kossa and birefringent to polarized light. The immunolabelling for OCN, OPN, and BSP was more intense for MTA and Bio-C Pulpecto on days 60 and 90 (P > 0.05). CONCLUSION: Bio-C Pulpecto was biocompatible, induced biomineralization and was immunopositive for osteogenic markers such as OCN, OPN, and BSP, similarly to MTA.

RESUMO

The aim of this study was to evaluate the immunolocalization of dentin matrix protein (DMP)-1 in human primary teeth treated with different pulp capping materials. Twenty-five primary molars were divided into the following groups: formocresol (FC), calcium hydroxide (CH), mineral trioxide aggregate (MTA), corticosteroid/antibiotic solution + CH (O + CH), and Portland cement (PC), and all received conventional pulpotomy treatment. The teeth at the regular exfoliation period were extracted for histological analysis and immunolocalization of DMP-1. Statistical analysis was performed using the χ(2) test (p < 0.05). Histological analysis revealed statistically significant differences in the comparison among the groups through the use of a score system regarding the presence of hard tissue barrier, odontoblastic layer, and internal resorption, but not regarding pulp calcification. Immunohistochemical analysis showed immunostaining for DMP-1 in groups CH, MTA, O + CH, and PC. Internal resorption was observed in the groups FC and CH. MTA and PC showed pulp repair without inflammation and with the presence of hard tissue barrier. DMP-1 immunostaining was higher for MTA and PC, confirming the reparative and bioinductive capacity of these materials.

RESUMO

Periodontitis is a chronic disease characterized by bone loss and inflammatory changes. We studied the effect of a homeopathic agent (Mercúrios Corrosivos 6 CH) and a non-steroidal anti-inflammatory drug (nimesulide) on the alveolar bone loss progression in experimentally induced periodontitis in rats. Sixty (60) Wistar rats were separated into group 1 (homeopathy), group 2 (nimesulide) and group 3 (saline solution). Silk ligatures were placed at the gingival margin level of the lower right first molar of all rats. Alveolar bone loss was evaluated by light microscopic analysis and analyzed using software Image J. The results were submitted to the analysis of variance (ANOVA) and Tukey’s posttest (p<0.05). The analysis revealed that there was a higher bone loss in diseased sites as compared with healthy sites. A significant reduction in the alveolar bone resorption was observed in group 2 (nimesulide) as compared with group 1 (homeopathy) 7 days after the induction of periodontitis. Our data provided evidence that homeopathy does not decrease alveolar bone loss as opposed to nimesulide in experimentally induced periodontitis.

RESUMO

OBJECTIVE: This study investigated and correlated the kinetic expression of vascular endothelial growth factor (VEGF)-A(165) messenger ribonucleic acid (mRNA) with the associated use or not of an infrared laser and a visible red laser during the wound healing in rats. BACKGROUND DATA: There is a lack of scientific evidence demonstrating the influence of low-level laser therapy (LLLT) on the expression of VEGF mRNA in vivo. MATERIALS AND METHODS: Forty-five Wistar rats were randomly allocated to one of three groups: I (n = 5, nonoperated animals), II (n = 25, operated animals), and III (n = 25, animals operated and subjected to laser irradiation). A surgical wound was performed using a scalpel in the right side of the tongue of operated animals. In group III, two sessions of laser irradiation were performed, one right after the surgical procedure (infrared laser, 780 nm, 70 mW, 35 J/cm(2)) and the other 48 h later (visible red laser, 660 nm, 40 mW, 5 J/cm(2)). Five animals each were sacrificed 1, 3, 5, and 7 days postoperatively in groups II and III, and samples of tongue tissue were obtained. The animals of group I were sacrificed on day 7. Total RNA was extracted using guanidine-isothiocyanate-phenol-chloroform method. The results of horizontal electrophoresis after reverse transcription polymerase chain reaction permitted the ratio of VEGF-A(165) mRNA and glyceraldehyde 3-phosphate dehydrogenase mRNA expression for groups I, II, and III to be assessed (two-way analysis of variance and Tukey test, p < 0.05). RESULTS: The expression of VEGF-A(165) mRNA in group II (0.770 +/- 0.098) was statistically greater than that observed in groups I (0.523 +/- 0.164) and III (0.504 +/- 0.069) in the first day after surgery (p < 0.05). Significant differences between the groups were not observed in other time periods. CONCLUSION: LLLT influenced the expression of VEGF-A(165) mRNA during wound healing after a surgical procedure on the tongue of Wistar rats.

RESUMO

Dental caries is a transmissible infectious disease in which mutans streptococci are generally considered to be the main etiological agents. Although the transmissibility of dental caries is relatively well established in the literature, little is known whether information regarding this issue is correctly provided to the population. The present study aimed at evaluating, by means of a questionnaire, the knowledge and usual attitude of 640 parents and caretakers regarding the transmissibility of caries disease. Most interviewed adults did not know the concept of dental caries being an infectious and transmissible disease, and reported the habit of blowing and tasting food, sharing utensils and kissing the children on their mouth. 372 (58.1%) adults reported that their children had already been seen by a dentist, 264 (41.3%) answered that their children had never gone to a dentist, and 4 (0.6%) did not know. When the adults were asked whether their children had already had dental caries, 107 (16.7%) answered yes, 489 (76.4%) answered no, and 44 (6.9%) did not know. Taken together, these data reinforce the need to provide the population with some important information regarding the transmission of dental caries in order to facilitate a more comprehensive approach towards the prevention of the disease.

RESUMO

Epidermolysis bullosa (EB) consists of a group of genetic hereditary disorders in which patients frequently present fragile skin and mucosa that form blisters following minor trauma. More than 20 subtypes of EB have been recognized in the literature. Specific genetic mutations are well characterized for most the different EB subtypes and variants. The most common oral manifestations of EB are painful blisters affecting all the oral surfaces. Dental treatment for patients with EB consists of palliative therapy for its oral manifestations along with typical restorative and periodontal procedures. The aim of this article is to describe two dental clinical treatments of recessive dystrophic EB cases and their specific clinical manifestations. The psychological intervention required during the dental treatment of these patients is also presented.

RESUMO

Furcal perforations may occur during access opening of the pulp chamber or cavity preparation. The perforation can cause an inflammatory reaction in the periodontal ligament. Management of these iatrogenic accidents can pose a significant clinical challenge, mainly when they occur in primary teeth. Current developments in the techniques and materials utilized for root perforation repair have enhanced this procedure's prognosis. Recently, mineral trioxide aggregate (MTA) has been used for several dental purposes. This biocompatible material promotes bone healing and elimination of clinical symptoms. The purpose of this case report was to describe the treatment of a furcal perforation using mineral trioxide aggregate (MTA) in a primary molar tooth. After 20 months, the tooth was asymptomatic. The radiolucent image had disappeared and bone formation at the furcation area had been observed, suggesting healing of the underlying periodontal tissues. Therefore, MTA may be considered an alternative option for the repair of furcal perforation in primary teeth, prolonging the longevity of these dental elements.

RESUMO

BACKGROUND: Vascular endothelial growth factor (VEGF) is a macromolecule of importance in inflammation that has been implicated in periodontitis. The aims of this study were to investigate VEGF expression during the progression of periodontal disease and to evaluate the effect of a preferential cyclooxygenase (COX)-2 inhibitor meloxicam on VEGF expression and alveolar bone loss in experimentally induced periodontitis. METHODS: A total of 120 Wistar rats were randomly separated into groups 1 (control) and 2 (meloxicam, 3 mg/kg/day, intraperitoneally, for 3, 7, 14, or 30 days). Silk ligatures were placed at the gingival margin level of the lower right first molar of all rats. VEGF expression was assessed by reverse transcription-polymerase chain reaction (RT-PCR), Western blot (WB), and immunohistochemical (IHC) analyses. The hemiarcades were processed for histopathologic analysis. RT-PCR and WB results were submitted to analysis of variance, the Tukey test, and Pearson correlation analysis (P <0.05). RESULTS: A reduction in alveolar bone resorption was observed in the meloxicam-treated group compared to the control group at all periods studied. There was a positive correlation between COX-2 mRNA and VEGF mRNA in the gingival tissues and periodontal disease (R = 0.80; P = 0.026). Meloxicam significantly reduced the increased mRNA VEGF expression in diseased tissues after 14 days of treatment (P = 0.023). Some alterations in VEGF receptor 1 mRNA expression were observed, but these were not statistically significant. VEGF protein expression in WB experiments was significantly higher in diseased sites compared to healthy sites (P <0.05). After 14 days of treatment with meloxicam, an important decrease in VEGF protein expression was detected in diseased tissues (P = 0.08). Qualitative IHC analysis revealed that VEGF protein expression was higher in diseased tissues and decreased in tissues from rats treated with meloxicam. CONCLUSIONS: The present data suggest an important role for VEGF in the progression of periodontal disease. Systemic therapy with meloxicam can modify the progression of experimentally induced periodontitis in rats by reducing VEGF expression and alveolar bone loss.

RESUMO

OBJECTIVE: This study compared the clinical efficacy of 4% articaine (A200) and 0.5% bupivacaine (B200), both with 1:200,000 epinephrine, for lower third molar removal. STUDY DESIGN: Fifty patients underwent removal of symmetrically positioned lower third molars, in 2 separate appointments, under local anesthesia either with A200 or B200, in a double-blind, randomized, and crossover manner. Time to onset, duration of postoperative analgesia, duration of anesthetic action on soft tissues, intraoperative bleeding, and hemodynamic parameters were evaluated. RESULTS: A statistically significant difference between the time to onset of A200 (1.66 +/- 0.13 minutes) and B200 (2.51 +/- 0.21 minutes) was found (P < .05). There was no statistically significant difference in the duration of analgesia, whether the patient was subjected to osteotomy or not, regardless of the local anesthetic used (3 to 4 hours; P > .05). However, when patients received B200 they experienced a statistically significant longer period of anesthesia on the soft tissues as compared with when they had received A200 (around 5 hours and 4 hours, respectively, P < .05). The surgeon's rating of intraoperative bleeding was considered very close to minimal for both anesthetics. In the surgeries with osteotomy, the comparison between A200 and B200 showed statistically significant differences in the diastolic (64 mm Hg and 68 mm Hg, respectively, P = .001) and mean arterial pressure (86 mm Hg and 89 mm Hg, respectively, P = .031) when data from all the surgical phases were pooled. Additionally, the mouth opening at the suture removal was statistically different for A200 and B200 solutions (91.90% +/- 3.00% and 88.57% +/- 2.38% of the preoperative measure, respectively) when surgeries required bone removal (P < .05). CONCLUSIONS: In comparison with 0.5% bupivacaine, 4% articaine (both with 1:200,000 epinephrine) provided a shorter time to onset and comparable hemostasis and postoperative pain control with a shorter duration of soft tissue anesthesia in lower third molar removal.

RESUMO

The treatment of a large dentine caries, which seemed to be a small pit-and-fissure carious lesion on the occlusal surface of the permanent mandibular right first molar in a 6-year-old boy, is presented. The treatment included the filling of the root canals and the sealing of the cavity with composite resin. Underlying periodontal tissue healing could be radiographically observed at the 14-month follow-up. It is possible that a better visual examination, with careful cleaning and drying of teeth, may improve occlusal caries detection. Dentists should examine bitewing radiographies carefully for occlusal demineralization. As radiographies are probably an effective method of lesions caries diagnosis, they should be recommended at appropriate ages to aid early detection of these lesions.


O tratamento de uma cárie grande do dentine, que pareça ser um lesion carious do poço-e-pit-and-fissure pequeno na superfície occlusal do primeiro molar da direita mandibular permanente em um menino de 6-year-old, é apresentado. O tratamento inclui o enchimento dos canais da raiz e do sealing da cavidade com resina composta. O tecido peridental subjacente que healing podia radiographically ser observado na continuação de 14 mês. É possível que uma examinação visual melhor, com limpeza cuidadosa e secagem dos dentes, pode melhorar a deteção occlusal da cárie. Os dentistas devem examinar radiographies do bitewing com cuidado para o demineralization occlusal. Porque as radiografias são provavelmente um método eficaz do diagnóstico da cárie dos lesions, devem ser recomendados em idades apropriadas ajudar à deteção adiantada desta lesão.

RESUMO

Traumatic dental injuries are relatively frequent accidents that typically involve teeth in the maxillary anterior segment. The emergency treatment and the clinical decisions must be efficiently made at the time of injury, and there is a need for long-term follow-up because of the high incidence of complications. The aim of this article was to present the emergency and rehabilitation treatments of a multiple dentoalveolar trauma in the permanent dentition involving different extensions of enamel-dentin crown fracture, pulp exposure, and the avulsion of a canine. The treatment outcomes are reported up to the 4-year follow-up, and the clinical approaches and their rationale are discussed.

RESUMO

PURPOSE: This study compared the use of 4% articaine in association with 1:100,000 (10 mug/mL; A100) or 1:200,000 (5 mug/mL; A200) epinephrine in lower third molar removal. PATIENTS AND METHODS: Fifty healthy volunteers underwent removal of symmetrically positioned lower third molars, in 2 separate appointments, under local anesthesia with either A100 or A200, in a double-blind, randomized, and crossed manner. Latency, duration of postoperative analgesia, duration of anesthetic action on soft tissues, intraoperative bleeding, and hemodynamic parameters were evaluated. RESULTS: A100 and A200 presented very similar latency (1.64 +/- 0.08 and 1.58 +/- 0.08 minutes, respectively; P > .05). Identical volumes of both anesthetic solutions were used: 2.7 mL = 108 mg of articaine plus 27 mug (A100) or 13.5 mug (A200) of epinephrine. The 2 solutions provided similar duration of postoperative analgesia regardless of bone removal (around 200 minutes; P > .05). The 2 solutions also had a similar duration of anesthetic action on soft tissues (around 250 minutes; P > .05). The surgeon's rating of intraoperative bleeding was considered very close to minimal. Transient changes in hemodynamic parameters were observed, but these were neither clinically significant nor attributable to the type of anesthetic used (P > .05). CONCLUSIONS: An epinephrine concentration of 1:100,000 or 1:200,000 in 4% articaine solution does not affect the clinical efficacy of this local anesthetic. It is possible to successfully use the 4% articaine formulation with a lower concentration of epinephrine (1:200,000 or 5 mug/mL) for lower third molar extraction with or without bone removal.

RESUMO

BACKGROUND: This paper describes the case of a 7-day-old girl who was referred to a paediatric dentistry clinic because of the presence of a pedunculated mass protruding from the front of her mouth. CASE REPORT: The mass was attached to the maxillary alveolus to the right of the midline, and was clinically diagnosed as a congenital epulis. The baby had no airway obstruction and was able to feed well. A conservative treatment was proposed, with monthly follow-up appointments to monitor the lesion. CONCLUSION: After 8 months, the lesion had completely regressed, meaning that the girl did not have to be exposed to unnecessary surgical procedures in her first few days of life. The eruption of the upper anterior teeth was not affected.

RESUMO

AIM: This study aimed at evaluating the prevalence of putative periodontal pathogens (Actinobacillus actinomycetemcomitans, Porphyromonas gingivalis, Prevotella nigrescens, Treponema denticola) in saliva of children with mixed dentition at two different time points, correlating these findings with a clinical parameter of gingival health. DESIGN: Polymerase chain reaction (PCR) detection was used to determine the prevalence of these bacteria in saliva of 64 children in 2003 and 60 children in 2004. Gingival health was assessed by gingival index. RESULT: Sixty-two (96.9%) and 50 (83.3%) children presented low gingival inflammation, whereas 2 (3.1%) and 10 (16.7%) had moderate scores in 2003 and 2004, respectively. Majority of the children (81.3% in 2003 and 73.3% in 2004) had detectable levels of at least one of the bacteria. The prevalence found was of 4.7% and 1.7% for A. actinomycetemcomitans, 6.3% and 8.3% for P. gingivalis, 23.4% and 48.3% for P. nigrescens (P < 0.05), and 71.9% and 50% for T. denticola (P < 0.05) in 2003 and 2004, respectively. No significant relationship between gingival index and presence of these bacteria and combination of different species was found. CONCLUSION: A high percentage of children harboured at least one of the putative periodontal pathogens in saliva, but presented periodontally healthy conditions.

RESUMO

UNLABELLED: Traumatic injuries to the teeth and their supporting structures are frequent in children. Among the traumatic injuries, dental avulsion results in the major functional and esthetic disturbances for patients. PURPOSE: The present study's aim was to assess the mothers' level of knowledge and attitude concerning dental avulsion. METHODS: A questionnaire contained 6 objective questions for the assessment of the mothers' knowledge and attitude regarding the management of dental avulsion and emergency procedures. RESULTS: A total of 242 mothers participated in the study. A lack of technical information was observed among the mothers. CONCLUSION: This study showed the need of a more effective communication between dental professionals and mothers to better handle dental emergencies. Educational campaigns and preventive programs on dental trauma must be organized to improve the emergency management of dental avulsion.

RESUMO

OBJECTIVE: This work aimed at performing a retrospective and comparative investigation of pharmacological therapeutic approach for pain and inflammation control for cleft lip and/or palate repair. STUDY DESIGN: Medical charts from 2000 patients who underwent surgical procedures at the Hospital for Rehabilitation of Craniofacial Anomalies, University of São Paulo (HRAC-USP), Brazil, were assessed to obtain information regarding type of cleft, surgical procedure, and analgesic and anti-inflammatory drugs prescribed. The first 1000 consecutive surgeries performed in 1992 and 2002 were assessed. RESULTS: Different analgesic and anti-inflammatory agents-nonsteroidal anti-inflammatory drugs (NSAIDS), steroids, and opioids-were given to patients perioperatively and postoperatively. NSAIDS were given to almost all patients (97.03% in 1992 and 99.88% in 2002, P > .05). Steroid administration increased in 2002 (8.66% versus 17.71%, P < .05). Opioids were administered only in 2002 (50.31%, P < .05). CONCLUSION: NSAIDS, steroids, and opioids were used for pain and inflammation control in cleft lip and palate repair at HRAC-USP. A change in the pattern of analgesic and anti-inflammatory drug use was observed when comparing 1992 and 2002. More potent compounds, such as opioids, were used in 2002 in a significant percentage of all the surgical procedures.
