ABSTRACT

Objective: This study assessed the variations in the perception of the smile line, according to examiners from three different social classes in the City of Cuiaba, Brazil.

Materials and Methods: A total of 12 smile photographs were taken of female students. These photographs were then classified according to the smile line profile presented by each volunteer (ideal, straight and reverse smile line). We selected which side of the smile matched the esthetic norms; later, the smile photographs were digitally duplicated and modified to obtain a symmetrical smile. After the changes were made, each volunteer was classified into the appropriate category. According to this classification, we carried out the alterations in the other two types of smile photos and placed them in an album for subsequent evaluation of the three types of smiles by examiners from three different social classes: A, B and C.

Results: There was a lower satisfaction of the subjects with regards to the reverse smile for the examiners from Class A. The lowest satisfaction for the Class B examiners was related to the reverse smile. Data of the comparisons among the Class C examiners revealed no statistical difference between groups (P > 0.05).

Conclusion: There was no statistical difference between the ideal and straight smiles.

ABSTRACT

Introduction: This study aimed to assess the peri-implant health of patients without maintenance therapy for 3 years.

Materials and Methods: The study sample consisted of 30 patients, from a specialization course, non-smokers, having single implants, and that had not taken antibiotics in the previous 6 months or presented any systemic disease that could interfere with peri-implant health. For comparison purposes, it was selected as control the tooth located in the three opposite side of the dental implant. Clinical examination was carried out by a senior examiner, consisting of the following exams: Visible biofilm, probing depth, clinical/peri-implant attachment level, and bleeding on probing frequency. After data collection, means were calculated for proximal regions and free faces, in addition to a general mean for all data. Data were compared and statistically treated by Student’s t-test for paired samples and Chi-square (P < 0.05).

Results: The data related to the variables under assessment showed no statistical difference between groups (P > 0.05).

Conclusion: It was concluded that even without implant maintenance therapy, there were no signals of disease progression in single implants for a minimum period of 3 years.

ABSTRACT

Introduction: Finishing and polishing materials did not develop as the composites improved in these last years. The nanometric load particles were firstly and only incorporated in the polishing pastes formulation in this in vitro and in situ study.

Objective: This study evaluated the biofilm retention of two different composite resins - Vit-l-escence® (microhybrid) and Filtek® Z350 XT (Nanofilled) after finishing and polishing technique, quantification and in situ comparison of the polishing pastes effectiveness with micrometric loads (Enamelize® and Diamond Polish Paste®) and Nanofilled load - Lummina-E (Alumina and Diamond).

Materials and Methods: Ten volunteers were selected for the in situ biofilm evaluation, a palatal device made of acrylic resin was confectioned, and each intra-oral device had fixed six specimens from each experimental group. After exposition to 20% sacarosis, the biofilm from each specimen was extracted in NaOH 1.0 M and quantified by absorbance spectrophotometer. The data were submitted to analysis of variance, followed for multiple comparisons of averages for the ad hoc de Dunn test, both at 1% significance level.

Results: Vit-l-escence® resin showed lower biofilm retention than Filtek Z350® XT in all the tested groups. The lowest biofilm retention was after aluminum oxide paste (Lummina-E - Alumina) polishing.

Conclusion: The Vit-l-escence® (microhybrid) composite resin exhibited lower biofilm retention than Filtek® Z350 XT (nanofilled) resin among all the tested groups. The lowest in situ biofilm retention occurred at the surfaces treated with Lummina - E Alumina (folder-based aluminum oxide) nanometric prototype.

ABSTRACT

Background: The objective of this paper was to present a methodology for osseointegration in rat mandibles.

Materials and Methods: A total of 16 Wistar male rats with 400 g were undergone to anesthesia, and then blunt instruments were used to expose the alveolar inferior nerve. Once the nerve canal was emptied, one implant (2.2 mm × 4 mm) was installed near the mandibular canal. The animals were sacrificed within the experimental period of 15 (n = 8) and 30 (n = 8) days. The histomorphometric analysis included both bone-implant contact and bone area.

Results: In a comparison of the variables between 15 and 30 days, there were differences in bone maturation (Student’s parametric test for independent samples - P < 0.05). In addition, the technique was shown to be reproducible and performed at a lower cost compared with histological studies involving other animals.

Conclusion: This specific technique of placing implants into the mandibles of rats is a viable alternative in studies of this nature.

Full Text PDF | Abstract |

ABSTRACT

Aims: Investigate the potential of curcumin, hypericin and photogem as antimicrobial agents in the antimicrobial photodynamic therapy (APDT) in Streptococcus mutans planktonic cultures.

Methods and Results: Susceptibility of S. mutans (ATCC 25175) to APDT using three concentrations of curcumin (250, 750 and 1000 mg l-1), hypericin (1, 5 and 10 mg l-1) and photogem (1, 5 and 10 mg l-1) was examined by colony-forming units method. Separated specimens of each group were irradiated using specific wavelengths (450 ± 10 nm, 590 ± 10 nm and 630 ± 10 nm). Results demonstrate absence of antibacterial effects for the groups that didn’t have the association of light with photosensitizers. Antibacterial effects were observed in the groups using photogem and hypericin. When compared with the positive control, the observed reductions were in the order of 6-logs up to the eradication of the treated cells. It is possible to co-relate the increase of photosensitizer concentration and irradiation time with higher antibacterial effect.

Conclusions: APDT have potential to be used as an oral disinfectant method.

Significance and Impact of the Study: APDT can be used prior to the execution of any oral treatment to decrease the dentist and staff exposure to a big bacterial load during the subsequent treatments and to lower the potential of environmental cross-contamination.

ABSTRACT

Objective: The purpose of this study was to evaluate the influence of the addition of 2% chlorhexidine digluconate (CHX) associated with 5% calcium chloride (CaCl2) on antimicrobial activity, setting time, pH and calcium release of gray mineral trioxide aggregate (GMTA).

Materials and Methods: GMTA powder was mixed with water, 2% CHX alone or 2% CHX combined with 5% CaCl2. Antimicrobial activity was determined against Enterococcus faecalis (ATCC 29212) strains by agar diffusion test. Data obtained were submitted to kruskal wallis tests. Analysis of the setting time was evaluated by American society for testing and materials C266-03 requirements. The pH and calcium release analysis were evaluated, in 24 h, 7, 14 and 28 days using pH meter equipment and atomic absorption spectrophotometer, respectively. Data obtained were analyzed by ANOVA, in 5% significance level.

Results: Significant differences were seen (P < 0.01) among the zones of bacterial growth inhibition produced by 5% CaCl2 + 2% CHX combination against E. faecalis when compared with water (P < 0.05). Regarding the setting time, that combination had the shortest setting time (P < 0.05). All associations were alkaline and released calcium. No statistical difference was observed between the experimental groups at the different periods of analysis (P > 0.05).

Conclusion: Combination of 5% CaCl2 + 2% CHX reduced the setting time and enhanced the antimicrobial activity of GMTA without changing the pH and calcium release.

Full Text PDF | Abstract |

ABSTRACT

Hidden caries is a type of lesion visualized in dentin, mainly by means of bitewing radiographs, in which, clinically, the occlusal enamel appears healthy or minimally demineralized and radiographically presents progressive demineralization in dentin, which may progress and compromise the pulp-dentin complex. Although the etiology of hidden caries is unknown, many theories have been studied, including structural and anatomical defects of enamel, their specific microbiota and the use of fluoride, which is most accepted theory. Considering the clinical concern, since these lesions have a silent progression and often are not detected on routine clinical examinations, this study aims to conduct a critical discussion of the etiology, prevalence, diagnostic methods and treatment decision for lesions of hidden caries, alerting professionals about the importance of routine use of bitewing radiographs even in patients considered “caries-free” or low risk of caries, for more effective diagnosis.

Full Text PDF | Abstract |

ABSTRACT

The “biological restoration” is an excellent technique for reconstruction in young traumatized teeth, which is used as intra-root reinforcement an extracted natural tooth. This article reports a case where an 11-year-old patient had his upper incisors affected by fractures from trauma. Due to the young age of the patient, the absence of the natural tooth fragment, the major structural loss and its high degree of anxiety, it was chosen to perform the treatment by this restorative technique that uses the “biological restoration” in addition to intra-root pins in an adjacent central incisor.

ABSTRACT

This case report presented a recently technique designed to promote an suitable reestablishment of interproximal contacts. This technique was first described in 2013 and favours the proximal faces rebuilding using materials such as gingival barrier, metallic matrix with the correspondent metallic ring and gliceryn. A female patient sought for aesthetic appearance of her posterior tooth. After clinical evaluation, proximal caries between the teeth 35 and 36 were found and removed. New restorations were performed using a customized ring technique. This technique presents advantages as better stability of the metallic ring and appropriate proximal contour showing satisfactory results.

ABSTRACT

Statistics - As it holds the semblance of truth associated to numbers – sounds like an exact tool, having no ambiguity, straight in the validation (or not) of scientific hypothesis and, in fact, it can be a powerful tool for the scientific research. This potential, added to the easy access to computers and eventual decrease of the cost of data processing, has led to a popularization of its use in scientific works.

Full Text PDF | Abstract |

ABSTRACT

Background: Desensitizing solutions based on diamine silver fluoride with a high concentration of fluoride generate an occlusion of dentinal tubules.

Objective: The aim was to evaluate the influence of time of application of diamine silver fluoride on the hydraulic conductance.

Materials and Methods: The sample of this prospective experimental study included 60 healthy human third molars with indications of extraction in malocclusion. These were extracted from patients between 18 and 30 years of age. Four groups of 15 dentin disks were obtained: GC (no treatment), G1 (were actively treated with diamine silver fluoride for 15 s), G2 (30 s), G3 (60 s). Then, was measured hydraulic conductance of dentin. The rate of flow of the fluid through the dentin disks was measured by recording the initial position of a bubble of air inside a capillary in 20 min.

Results: The hydraulic conductance obtained are: GC= 0,0433 (± 0.0210); G1= 0.0087 (± 0.0063); G2= 0.0082 (± 0.0050) and G3= 0.0061 (± 0.0040) expressed in µL/min*cm2. With the Wilcoxon signed rank test, it was established that there is a statistically significant difference in hydraulic conductance between the control group and the samples treated with desensitizing solution based on diamine silver fluoride/potassium iodide. There was no statistically significant difference between the groups treated with different application times of the desensitizing solution.

Conclusion: There was no difference in hydraulic conductance between disks with different application times of desensitizing solutions of diamine silver fluoride/potassium iodide.

Full Text PDF | Abstract |

ABSTRACT

Introduction: Dental care triggers feelings such as fear, anxiety, stress and apprehension in most patients. These, in turn, generate physiological changes that result in some systemic changes, such as blood pressure (BP).

Objective: To evaluate the change in BP of patients undergoing tooth extractions.

Materials and Methods: We evaluated 70 patients of both genders, randomly selected in the clinic of surgery and anesthesiology of a certain university. Each patient answered a questionnaire and then had the BP measured before, during and after surgery.

Results: The results showed that there is a significant variation in BP in these three evaluated moments; there is no statistical difference between genders and the variation of pulmonary artery; it was found a significant association (P < 0.05) between the change in BP in the operating trans and patient age.

Conclusion: There was a variation in BP of patients undergoing tooth extractions, which showed higher values in the trans-operative period. This increase is related to fear and anxiety during dental care.

Full Text PDF | Abstract |

ABSTRACT

Cleft lip and palate are among the most common craniofacial anomalies of the human species causing considerable morbidity to affected individuals. The etiology of isolated or non-syndromic cleft lip and palate is complex and heterogeneous, and its occurrence is associated with the interaction of different genetic and environmental factors. To explore the genetic and environmental factors involved in the etiology of non-syndromic cleft lip and palate, an extensive literature review was conducted on PubMed and SciELO databases. A number of environmental factors such as smoking, alcohol consumption, diet quality, supplementation with folic acid, exposure to chemicals and contaminants, parental age and medication use may be associated with mutations in several genes increasing the risk of development of cleft lip and cleft palate. Advances in the study of gene-environment interactions and the expansion of knowledge about its etiology should lead to improvements in the prevention, diagnosis and treatment of non-syndromic cleft lip and palate.

Full Text PDF | Abstract |

ABSTRACT

The burning mouth syndrome (BMS) is a chronic orofacial disease characterized by symptoms of burning or burning in the oral mucosa without being able to detect lesions or clinical change. Its etiology is multifactorial and affects mainly women in the postmenopausal periods. Treatment should be multi-disciplinary, but the complexity of the etiology knowledge hinders the establishment of the most appropriate treatment. Therefore, this study evaluated the use of acupuncture in the treatment of BMS. Through literature review, it can be noticed that the union of the concepts with the teachings of traditional Chinese medicine can provide a new perspective for the treatment of pain/oral burning as acupuncture treats the individual as a whole, in an attempt to restore the balance between the organs. Thus, various pharmacological effects can be achieved, such as analgesic, muscle relaxing, sedative, antidepressant, anti-inflammatory, repair stimulating, and immunity promoter, which might have a great efficacy in the treatment of BMS.

ABSTRACT

Odontomas are mixed odontogenic tumors composed of mineralized tissue of ectomesenquimal origin. According to the World Health Organization (WHO) ranks, the odontomas are classifi ed into two main types: Complex and compound. They are usually detected in routine radiographs and may be related to various causes, and are rarely associated with impacted teeth. This article aims to present the clinical and histopathological features of this tumor through a case report. The female patient, 18-year-old, sought dental care and reported pain, swelling, and bleeding in the region of the impacted tooth 48. A lesion was observed in the image exam, so a biopsy was performed. The result of the biopsy confi rmed that, it was a case of complex odontoma in the posterior mandible, which was removed by technical curettage of the lesion.

ABSTRACT

Full arch implant-supported prostheses following Branemark protocol are widely used for oral rehabilitation of people with edentulous jaws and associated to the full upper conventional prosthesis. Their indication requires that the dental surgeon be prepared for prosthetic-surgical approach and planning. Therefore, this work aims to present the planning and execution of a lower arch implant-supported immediate-load prosthesis associated to a conventional upper prosthesis through a clinical case report. Previous planning on the installation of the implants aims at the proper fixation after defining the prosthesis design. Predictability of results and patient satisfaction demonstrate how important this planning is.

Full Text PDF | Abstract |

ABSTRACT

Background: Computed tomography (CT) is a non-invasive, rapid, reliable, and highly accurate diagnostic method. The frequency of impacted canines in the maxilla is 7 times greater than in the mandible and they are related to resorption of adjacent teeth.

Objective: The aim of this study was to evaluate and classify the degree resorption of teeth adjacent to upper canines with disturbance eruption by CT.

Materials and Methods: The images of 55 patients with 73 maxillary canines with eruption disorders were analyzed using a specific navigation software for cone beam CT scans in two planes, transverse and axial, looking for root resorption in maxillary incisors adjacent to canines with an eruption disturbance. For statistical analysis, the data were subjected to Student’s t-test for paired samples and Pearson’s correlation test (P < 0.05). The Kappa coefficient was used to evaluate the agreement between the first and second readings performed by the examiner (0.758).

Results: In the presence of retained canines observed increased risk of resorption in lateral incisors; most likely position of these elements is lingual; the reading of the cutting planes are indifferent diagnosis.

Conclusion: From the sample analyzed in this study, it is possible to conclude that when canines with eruption disorders exist, a tomographic analysis should be asked by the risk of reabsorption in surrounding tooth roots.

ABSTRACT

Objective: The aim of this study was to evaluate the efficacy of a bleaching material (hydrogen peroxide [HP]) in different concentrations (20% and 35%) as well as the susceptibility to staining after the bleaching procedure.

Materials and Methods: The root portions of 20 healthy bovine incisors were removed, and the crowns were sectioned, obtaining mesial and distal halves, totaling 40 specimens. The specimens were identified as 1-20 (G1) for the mesial half and 21-40 (G2) for the distal half. The specimens of G1 were subjected to staining with coffee and subsequently subjected to bleaching with HP 35% (specimens 1-10) and HP 20% (specimens 11-20). The specimens of G2 were stained with acai berry and later bleached with HP 35% (specimens 21-30) and HP 20% (specimens 31-40). After bleaching, the specimens were again subjected to staining with the same substances. The colorimetry system (CIELab) was carried out with a spectrophotometer at five different moments: Before the first staining, after the first staining and previously to the first session of bleaching, previously to the second bleaching session, previous to the second staining, and finally after the second staining.

Results: No difference was found between HP 35% and 20%, and both materials significantly promoted bleaching.

Conclusions: The acai solution resulted in more staining compared to the coffee solution, before and after bleaching. No increase was observed in susceptibility to staining after bleaching of the bovine teeth.

ABSTRACT

The direct anatomical posts (composite resin associated with prefabricated glass fiber posts) become a new treatment option for rehabilitation of weakened roots. From a literature review, this paper aims to prospect the indications, advantages, preparation technique illustrated by a step-by-step protocol and results of in vitro studies about this new proposal for restorative treatment of weakened roots, which is presenting itself as a suitable alternative to conventional cast metal post-and-cores. Clinical significance: In clinical practice, the dentist is faced daily with the need to restore teeth with weakened roots. In such cases, the technique of direct anatomical posts has been presented as a good alternative because it involves a technically simple procedure and allows to obtain biomechanical and esthetic favorable results.

ABSTRACT

Central giant cell lesion (CGCL) is an uncommon alteration of obscure etiology that, although benign, can be highly destructive. This paper presents the case of a patient with CGCL addressing its diagnosis and treatment. An 18-year-old male patient with facial asymmetry due to significant volumetric increase in the right parotidmasseteric and submandibular regions with 9 months of evolution attended the Department of Dentistry of Mato Grosso Cancer Hospital. After clinical and imaginological examinations, an incisional biopsy was performed leading to the diagnostic of CGCL. With the negative results for hyperparathyroidism, the lesion reduction was attempted with corticosteroids infiltrations. Due to the lesion extension and the lack of response to the infiltrations, the resection was performed. The patient is in attendance for 2 years without any symptoms of recurrence. Although more prevalent among female, young adults and elderly, the CGCL may present in other patients and the professional must be aware. The therapy of choice in this pathology varies with the aggressiveness and extension of the lesion. More aggressive lesions can lead to more extreme clinical management and involve the need for surgical resection.

ABSTRACT

Purpose: The aim of this study was to evaluate the epidemiological data, socioeconomic status and prevalence of patients with facial fractures treated at a hospital and an emergency room service from March to August of 2014.

Materials and Methods: This cross-sectional study analyzed the epidemiological and demographic data related to these patients. Data were subjected to statistical studies with a significance level of 5%.

Results: There were 1348 patients attended to during this period and of these, 144 patients presented facial fractures. Most patients involved were men, the mean age of 32.37 years, social Class C, married, living with more than three persons, and 52.1% from the interior of the state. The most affected bones were the mandible, zygomatic complex, nasal, maxillary, and frontal. Most cases involved automobile accidents (45.8%) of these, motorcyclists (38.9%), automobiles (6.3%), trucks (0.7%).

Conclusion: From the casuistry of this study, it was concluded that most patients consist of young adults, male, non-white, married, and with low education. The prevailing socioeconomic class is Class C, and most have their own house and are financially independent. A slight majority of the patients come from the interior of the state. Regarding etiology, most were from car accidents and the use of safety equipment was neglected in most cases. The bones fractured most often are the mandible and the bone of the zygomatic complex.

ABSTRACT

Dentin hypersensitivity (DH) is a common patient complaint in the dental surgery. This pain is associated to dentin exposure and non-carious cervical lesions. The knowledge of the lesions types, etiology, and characteristics has been a challenge for dental professionals.

Objective: This study aimed to compare the effectiveness of low-level laser therapy and a desensitizer containing strontium chloride on cervical DH.

Materials and Methods: Patients presenting non-carious cervical lesion caused by abrasion, erosion, abfraction or enamel, and cementum loss by the gingival recession were selected and divided into two groups: Group 1 (Desensibilize® - desensitizing agent) and Group 2 (Whitening Lase II® - laser therapy). The teeth were selected in pairs presenting no hypersensitivity and were compared to their homologous. The teeth were submitted to stimuli and the patient assessed using a pain subjective scale. The data were analyzed using the SAS statistical program and submitted to Kruskal–Wallis and Friedman tests at 1% significance level.

Results: Significant differences were found between the groups, Group 1 (Desensibilize®) presented 90% efficiency and Group 2 (Whitening Lase II®) 95% efficiency. After three sessions, both desensitizing methods effectively reduced the DH.

Full Text PDF | Abstract |

ABSTRACT

Introduction: There is a clear lack of knowledge among professionals about the use of local anesthesia during dental treatment in cardiac patients, coming to delay emergency care or to indicate the use of vasopressors erroneously since its use brings benefits to the patient and the professional.

Objective: To evaluate professionals’ perception of the use of local anesthetics with vasoconstrictors to perform dental procedures in patients with heart disease.

Methods: This study was conducted by the application of a questionnaire that contained 12 questions which 100 professionals answered from January to September 2014.

Results: 61% of professionals recommend that the use of local anesthesia associated with a vasoconstrictor to dental treatment for a cardiac patient. Half of them did not know to answer, “What is the concentration of vasoconstrictor recommended for use in a cardiac patient?” 81 professionals choose the lidocaine as the best anesthesia.

Conclusion: The professionals demonstrate to know about the use of vasoconstrictors associated with local anesthetics in dental procedures; however, the total amount and concentration of the vasoconstrictors are unknown.

ABSTRACT

The aneurysmatic bone cysts are uncommon bone injuries, but well-recognized occurring a more frequent in long bones and vertebrae of patients with <30 years. As a distinct entity, it was first described by Lichtenstein, they rarely occur in the maxillary sinuses, which may occur concomitantly with other injuries such as brous dysplasia, and central injury of giant cells. The etiology and pathogenesis of this injury are still not completely elucidated, and there is controversy whether injuries arise anew or represent some form of vascular accident in a preexisting injury. Their clinical characteristics such as fast growth, expansion, cortical destruction and osteoid formation can easily confuse the clinician about malignant injuries. This is a case report of a pediatric patient treated of an aneurysmal bone cyst (ABC) associated with juvenile ossifying broma in Buccal Maxillofacial Surgery of Service of Pedro Ernesto Hospital.
