Authors: Souza Karin Faust , Miranda Carla , Almeida Izabel Cristina Santos
Published: March 2017

The purpose of this study was to evaluate in vitro the effect of APF, gel and foam, for 1 to 4 minutes, on artificial enamel caries-like lesion of primary teeth submitted to the pH cycling. The specimens with medium values of initial superficial enamel micro-hardness between 272 and 331KHN were selected for the formation of the artificial caries lesion. Later, they were randomly divided into 6 groups (n=15): no pH cycling control, cycled control, gel 1min, gel 4min, foam 1min and foam 4min.The no pH cycling control group was maintained in an humid environment, while the application of APF and the pH cycling were accomplished. After, the specimens were sectioned at the center for the enamel cross-sectional micro-hardness test. The values of micro-hardness of the depths from 20 to 180mm were converted into percentile of mineral volume (%Vol) and the area of mineral recovery (∆ZR) was calculated.  In spite of there is no statistically significant differences, it was observed through the analysis of the ∆ZR a difference in the values for the groups gel 1min and foam 4min (p>0.05). The evaluation of %Vol indicated a significant difference only at 60mm depth (p=0.005). This study concluded that a single application of APF gel or foam, for 1 or 4 minutes, do not remineralize artificial enamel caries-like lesion of primary teeth

Published: March 2017

This study evaluated the effect of the addition of 5% calcium chlorite (CaCl2) on pH values in calcium hydroxide pastes (CH), with or without 2% chlorhexidine digluconate (CHX) used as vehicle, in several periods analysis. Polyethylene tubes were filled with CH mixed with water (G1), 2% CHX solution (G2) or gel (G3), or CHX solution  or gel with 5% CaCl2 (G4 and G5, respectively). All tubes were individually immersed in distilled water. After 12, 24 hours, 7, 14 and 28 days, pH value was evaluated directly in water which the tubes were stored. Data were submitted to ANOVA and Tukey tests (α=0.05). In 24 hs and 14 days, pH values were similar to all groups. In 12 hs, the G1 presented lower pH value than other groups except to G4 (p < 0.05), and G4 presented lower pH value than G5 (p < 0.05). In 7 days, G1 presented lower pH value than G4 and G5 (p < 0.05). In 28 days, G1 and G5 presented lower pH values than G2 and G4 (p < 0.05) and among other groups there are no statistical differences (p > 0.05). The pH values increased in long-term analysis to all CH pastes. The association of 5% calcium chloride with 2% CHX solution as vehicle of CH paste provided a pH value increase in relation to CH mixed with distilled water. The CHX gel interfered negatively on pH value in comparison to CHX solution when mixed with CaCl2.

Purpose: The aim of this in vitro study was evaluate the microhardness in dental composites photo activated in a distance of 8mm, what simulates the first composite increment in a restoration class II. Thereunto, 45 specimens were confectioned using a nanopaticulate composite (Filtek Z350 – 3M Espe. The specimens were divided randomly in 9 groups (n=5). Each group differed in the photoactivation mode used (1600 mW/cm2 Bluephase 16i (BLP); 800 mW/cm2 Ultralume 5 (ULT); 500 mW/cm2 XL3000 (XL)) and in the temperature of composite in the moment of polymerization (23°C, 54°C or 60°C). After the preparation of specimens, they were submitted to the microhardness Knoop test (KHN) on the surfaces and bottom, and the results were charted and submitted to the statistical analysis. There were no significant statistical differences in relation to the photoactivation modes used for all the surfaces and temperatures tested. For ULT, there was no significant statistical hardness in relation to the temperature of the composite. For XL and BLP modes, the increase in the temperature (56◦C and 60◦C) provided a hardness rise in the composite on both surfaces; for XL the temperature 56◦C did not differ from the control (23◦C); for BLP the temperature 60◦C did not differ from the control. For all the situations tested, the top surface presented greater hardness than the bottom.

AIM: The aim of this work was evaluate the insertion and removal torque for orthodontic mini-implants inserted in different inclination. MATERIALS AND METHODS: Ten self-drilling mini-implants from the brand SIN (Sistema de Implantes Nacional, São Paulo/SP, Brazil), and the surgical kit for their insertion were used. Two plaques of synthetic bone of 120 mm x 170 mm x 41,5 mm were used (Sawbones, Pacific Research Laboratories Inc, Vashon, Wash), with 1,5 mm height, simulating the cortical bone (density 40 pcf) and 40 mm simulating the medullary bone (density 15 pcf). In each block, five areas were demarcated for each mark, totalizing ten areas. The ten mini-implants were inserted by the same operator, previously calibrated; five of them at 900 and five at 600, using the manual key kit. After the insertion of all the mini-implants, the final threading and the reading of insertion torque value were carried out with a manual torque wrench digital Lutron TQ-8800 (Lutron Electronic Enterprise Co., Ltd, Taipei, Taiwan) until the trans-mucosal profile achieve the cortical bone. The maximum insertion torque value was registered in N/cm. After all the implants inserted, the measurement of removal torque was started, performed in the same way of insertion, but in the opposite anticlockwise. The results were submitted to the T test (parametric) and to a Mann-Whitney test (non-parametric). RESULTS: The results demonstrated that the insertion torque was lower than the removal one in both insertion degrees, with statistically significance. Despite insertion torque at 90 degrees had been lightly higher than that inserted at 60 degrees, they were not statistically significant. CONCLUSION: In view of the results, it was possible conclude that insertion at 60º angulation does not offer advantages to the primary stability for orthodontic mini-implants.

Published: March 2017

AIM: The aim of this study was to verify two different types of interfaces in Morse taper connection implants, relating the mechanical resistance to a loosening torque that is required to separate or move the prosthetic abutment. MATERIAL AND METHODS: Ten Morse taper connection implants and their respective abutments were divided into two groups (n = 5), DH (double hexagon) interface and OI (octagonal implant) interface. A standard insertion of implants was performed in a stainless steel base, where each abutment received a sequence of two consecutive tightening torques at a 10-minute interval, followed by a loosening torque, which was measured using a digital torque gauge. The Student’s t-test with a 5% significance level was used for data analysis. RESULTS: The results showed a statistically significant difference in the loosening torque values compared with DH torque values (p < 0.05). However, the difference between tightening and loosening torque values was not statistically significant in the OI group (p = 0.465). CONCLUSION: The study concluded that there was a difference in the torque required to loosen the abutment screws between the DH group and the OI group, with the latter showing better results.

AIM: The aims of this study were to assess the penetration of two endodontic sealers (salicylate and epoxy resin-based sealers) into dentinal tubules using CLSM; and to evaluate the bacterial leakage of roots filled with the same sealers associated with gutta-percha. MATERIAL AND METHODS: For sealer penetrability assessment, thirty bovine roots were instrumented and divided into three groups: AHP: EDTA + filling with AH Plus and gutta-percha (n=10), MTAF: EDTA + filling with MTA Fillapex and gutta-percha (n=10), control group: canals were not irrigated with EDTA and were filled with gutta-percha and AH Plus (n=5) or MTA Fillapex (n=5). Rhodamine B was added to the sealers in order to provide adequate fluorescence. The roots were transversely sectioned 3mm from the apex to enable CLSM analysis. Leakage was evaluated for turbidity of the broth in a split chamber model system for 30 days, using Enterococcus faecalis as a microbial marker. Thirty roots were instrumented and divided in four grupos: AHP: filling with AH Plus and gutta-percha (n=10); MTAF: filling with MTA Fillapex and gutta-percha (n=10); positive control: filling with gutta-percha without sealer (n = 5); negative control: sealing with cyanoacrylate to test the seal of the system (n = 5). RESULTS: The medians for dentinal tubule penetration were 6.8% (AHP) and 6.6% (MTAF) (P = 0.82). The average time for bacterial leakage was 8 days in both experimental groups (P = 0.79). CONCLUSION: MTA Fillapex and AH Plus presented similar behavior regarding dentinal tubule penetration and bacterial leakage.

Odontogenic myxoma in children: case report
Authors: Naves Neto Valdor , Sartori Ivete , Oliveira Laudimar , Bugarin Júnior João , Souza Danilo , Cardoso Frederico , Coutinho Helio
Published: March 2017

Odontogenic myxoma is a rare tumor, often diagnosed during routine radiographs or when it is so severe that it causes pain, a noticeable increase in volume or tooth displacement and mobility. Young adults (25-30 years of life) are more often affected by the lesion but all ages are vulnerable. The mandible is more commonly involved than the maxilla and the tumors usually grow slowly and silently. However, growth can be rapid and destructive. The radiographic aspect of a myxoma is that of a uni or multilocular, radiolucent lesion reminiscent of honeycomb or soap bubbles, depending on its size. It is an expansive tumor that may cause displacement or resorption of the teeth involved. Microscopically, the tumor is composed of round and spindle cells, with a star arrangement, arranged in a loose abundant myxoid stroma, containing only a few collagen fibrils. The treatment of choice is radical surgical excision because myxomas are not encapsulated and tend to infiltrate the surrounding bone. However, small tumors can be treated by curettage. Periodic reassessment is required for at least five years due to the high rate of recurrence. Larger tumors may need to be treated using a more extensive resection with a safety margin. This study reports a clinical case of odontogenic myxoma in a child aged 7 years. The tumor was located in the posterior region of the mandible and was surgically treated with an en bloc resection with preservation of the base of the mandible. The follow-up of the case is ongoing and no recurrence has been observed to date.

Published: March 2017

AIM: To evaluate the esthetic attractiveness of the Sky Hook type of maxillary protractor, available in different colors. MATERIAL AND METHODS: Eight Sky Hook type of maxillary protractors of different colors were evaluated. Images were obtained of the same patient, and standardized with the aid of an image manipulation program (Adobe Photoshop software from CS) to obtain the colors: white, gray, green, yellow, blue, pink, brown and black. After acquisition the images were printed on photographic paper and incorporated into a specific and personalized questionnaire. The questionnaire was distributed among children of both genders, in the age-ranges from 7 to 8, and 9 to 10 years, at public and private schools (n=200). Fro the scores attributed to each image, the Mann-Whitney test was used, and among groups, Spearman’s Correlation. The level of significance adopted was 5%. RESULTS: The scores attributed to the color green presented significant difference between the schoolchildren from public and private schools. In a comparison between genders, the boys awarded better scores to the colors gray and black, whereas the girls awarded better scores to the color pink. When the age groups examined were compared, only the color blue presented statistical differences. CONCLUSION: The color of the Sky Hook type of maxillary protractor has an influence on the esthetic attractiveness to children from 7 to 10 years, and preference determined by colors is also influenced by gender and the type of school (public or private) and age group.
Non surgical management of large periapical lesion using mta: report of 2 cases
Authors: Noushad MC , Niyaz Mohammed , Peedikayil Faizal C , Pradeep CV , Sebastian Anish , Arafath Muhammed Yazar
Published: March 2017

In the past, cases with open apices were often treated over several appointments, using calcium hydroxide, with the hope of creating a ‘‘calcific’’ barrier against which gutta percha could eventually be placed. The treatment could be as long and the prognosis is questionable. These roots were often thinner and, therefore, more brittle; extending treatment over a long period of time without providing a permanent restoration increased the chances of losing these teeth due to fracture. With the favorable histologic response of MTA, this material is the best current choice for this procedure. Completion of these cases in an effective and efficient way allows for permanent restorations to be done in a timelier manner, prolonging the longevity of these teeth. The following case report demonstrates the use of MTA as an obturating material to promote periapical healing with an open apex.

Published: March 2017

AIM: This research evaluates the dimension characteristics of jaw and the inter arches relation in children with reduction of nasopharynx space by hypertrophy of the pharyngeal tonsils in the mixed dentition stage. MATERIAL AND METHODS: the sample was composed by initial orthodontic documents of 25 patients of both genders, from 6 to 10 years old, diagnosed with nasopharynx obstruction by two specialists (one orthodontist and one otorhinolaryngologist) based on anamnesis, medical history, clinical tests, face photos and evaluation of the respiratory airways through lateral telereadiography. In this early moment, occlusal characteristics were not considered during the diagnosis. The sample was composed by only the cases in which both professionals considered presenting significant obstruction of airways (isthmus ≤ 4mm), able to provide changes on growth and occlusion and that presented the inclusion criteria. The cases selected had their initial plaster models evaluated by means of a digital caliper (brand Vonder) previously calibrated. The intra arches and inter arches included in this study were: intercanine and intermolar distance; anterior and total length of dental arch, depth of the dental arch overjet, overbite and terminal plan/molar and canine relation. RESULTS: It was not found correlation among the isthmus values and variable analyzed. Intra arches measurements presented similar behavior among them, showing their severity. CONCLUSION: Intra arches and inter arches analyzed showed values similar to them reported in the literature, evidencing the influence of nasopharynx space reduction on the morphology of arcade and on occlusion.

AIM: A retrospective clinical analysis evaluated the clinical behavior of the prosthetic restorations, screw joint stability, peri-implant bone level and soft tissues, implant survival rate and patient satisfaction. MATERIAL AND METHODS: Data was collected from follow-up visits of 444 patients, aged from 26 to 88 years, that were rehabilitated with 2,244 implants placed between 2005 and 2010. RESULTS: The implant survival rate was 99.73%, 94.78% for prosthetic screws, and 96.70% for abutment screws. Peri-implant bone levels remained stable (bone loss equal or less than 1 mm) in 96.21% of the implants. Plaque accumulation was present in 275 patients and was associated with gingival bleeding in 66 patients. Three hundred and thirty patients were satisfied, 103 were somewhat satisfied, 7 patients expected more from their restorative treatment, and 4 patients were dissatisfied. CONCLUSION: Continuous follow-up of patients with implant restorations provides essential information on the behavior of implants and prosthetic components, enbling the early intervention in minor prosthetic complications (e.g. screw loosening) to avoid future major complications (e.g. implant failure).

Published: March 2017

Invasive cervical resorption is entirely an uncommon entity in dental community that is not well understood. Accurate diagnosis of the situation and immediate treatment execution are prerequisites for long term retention of the tooth. Treatment procedure includes elimination of the resorptive tissue followed by restoring the defect with a suitable biocompatible material. The necessity of endodontic treatment depends on whether the defect had invaded the root canal or not. This case report elaborates the surgical management of a class IV invasive cervical resorption in the central incisor followed by restoration of the defect with biodentine.

AIM: The aim of this study was to evaluate the efficacy of different lengths of time of passive ultrasonic irrigation (PUI) in removing calcium hydroxide (CH) paste from root canal, using scanning electron microscopy and energy dispersive spectrometry (SEM/EDS). MATERIAL AND METHODS: Fifty-four human premolars were used. After coronal access, a size #15 K-file was used to obtain apical patency. Root canal preparation was performed using WaveOne 40.08 instruments. CH paste was placed into the root canal. Specimens were stored in a humid environment, and after seven days, they were divided into five groups (n=12) according to the irrigation protocols: Manual– a size #40 K-file; PUI/1– 1 min; PUI/2– 2 min; PUI/3– 3 min; and Control– without CH paste. An elementary chemical microanalysis (SEM/EDS) was performed to quantify the presence of calcium on the dentinal walls. RESULTS: The percentage of calcium was higher in all experimental groups when compared to the control group (P < 0.05); but no differences among them were found (P > 0.05). CONCLUSION: The amount of calcium hydroxide paste on the dentinal walls was not dependent on length of time of ultrasonic activation. SEM/EDS analysis seems to be a reliable method to assess CH paste removal from the root canals.

The WHO Oral Health Assessment Form was used to record the oral health status. The Simplified Oral Hygiene Index and Gingival Bleeding Index were also included. Unstimulated saliva was collected. Immunoglobulin A levels in saliva was estimated by Turbidimetric Immunoassay. Salivary Cortisol was analysed using ELISA method. For TAC thiobarbituric acid reactive from Fenton’s reaction. RESULTS: Since the absolute difference of the salivary parameters between the pairs of twins was not symmetrically distributed, we report median and interquartile range to describe these differences. There were no observed significant variations in the above salivary parameters. CONCLUSION: The similarity in their environmental factors as well as perhaps the similar genetic predisposition on salivary factors has led to the similarity in the dental caries experience in these twin children.

AIM: This study aimed to report a case in which the technique used was the atraumatic Restorative Treatment (ART) in patients with fear of conventional treatment. MATERIAL AND METHODS: This procedure consisted in the treatment of carious lesions in the patient associated with the program of educational and preventive measures which the patient has undergone. The technique described here was performed on tooth 85, which presented atypical carious lesion cavity, through the removal of softened carious tissue with the use of hand instruments, without anesthesia and use of direct restorative material with fluoride release (glass ionomer cement). RESULTS: As a result of this technique, there was greater patient cooperation and decrease of anxiety initially revealed. CONCLUSION: Thus, it might be concluded that the Atraumatic Restorative Treatment is a technique already established that showed clinical effectiveness in controlling the evolution of the carious process and that being well indicated, was able to induce more cooperation from the patient, leading to the success of therapy restorer. The conventional glass ionomer cement showed excessive surface wear and therefore should not be used to restore atypical cavities.

AIM: This research aims to investigate the development of this habit’s appearance, which may be observed even at the intrauterine stage and which also persists for a long time. MATERIAL AND METHODS: 25 gestations that presented children practicing intrauterine digital sucking habits were followed-up. The initial analysis was accomplished through routine ultrasound examination, using pregnant women between the 4th and 8th gestation months who visited João de Barros Barreto University Hospital. Detecting this habit, every quarter an afterbirth accessory was carried out,over a 1 year period, in order to observe the habit’s persistence. This phase was developed in the Dental Office of the Brasil Sorridente Program. Statistical analysis were carried out regarding the obtained outcomes using the described statistics and inferential methods, and the Chi-square test with 5% significance level was applied. RESULTS: This research observed that 72% of babies were male gender and 28% female gender, 68% of babies persisted with the digital sucking habit 1 month afterbirth, 72% until the second month, 56% until the fifth month and 48% until one year old. Assessing the habit’s post natal persistence according to gender, the binominal test was applied which was significant (p=0.0186). It was concluded that the number of male babies with digital sucking habit was above the female gender (p=0.0455), the habit’s persistence was reduced by 50% when compared with the first month, however, the p=0.2474 indicates that the reduction was not significant. CONCLUSION: Our outcomes cannot be generalized; however they can be used as a base for future research in this area.

AIM: The purpose of this study was to describe the external and internal anatomy of the mandibular premolars. MATERIAL AND METHODS: 100 extracted human permanent mandibular first and second premolars teeth were collected. The length of the tooth from the cusp tip to root apex was measured with the help of Vernier calliper. In case of curved roots, ligature wire was adapted to the root and then straightened and measured. Each tooth was examined for the number of roots, curvature of root, presence of root canal invagination. India ink was injected into the pulp chamber through the access opening with a no.27 gauge needle mounted on a disposable syringe. The ink was then drawn through the root canal system by applying negative pressure to the apical end of tooth with the use of central suction system. RESULTS: The average (mean) length of mandibular first premolar was 22.25 mm. Average (mean) length of mandibular second premolar was 21.90 mm. Mandibular first premolar had a ribbon shaped root canal orifice in 35% of teeth. Mandibular second premolar had a ribbon shaped of root canal orifice in 44% teeth. Mesial invagination of the root was found in 18% of first and 8% second mandibular premolar teeth. 78% had a Type I canal pattern with Type II, Type IV, Type V, Type VI and Type VII canals being identified in 1%, 2%, 13%, 2% and 1% of the teeth respectively. CONCLUSIONS: Complex root canal anatomy frequently found with mandibular premolars among which more common with mandibular first premolars in Indian population.

Immune thrombocytopenic purpura (ITP) is a disease associated to the decrease of platelet count in peripheral blood, with repercussion on the oral cavity, due to the potential risk of spontaneous bleeding or provoking it. The aim of this work was evaluate the relation between the platelet count of chronic IPT patients and their periodontal condition. Thereunto, 31 patients were evaluated; 15 with this pathology (group 1) and 16 Dentistry students with no hematologic disease (group 2). Both groups were examined in their periodontal condition through gingival condition index (G), periodontal attachment loss (P) and gingival recession (R), as well as blood tests were performed to verify the platelet count, further a questionnaire on the socioeconomic aspects, access to dentistry services and mouth health self-perception. It was observed that 68.8% of IPT patients’ mouth sextants presented some degree of gingivitis, despite some 16.8% manifested loss of periodontal insertion. Gingival retraction occurred in only 2 patients of the group 1, and the average measure for this event in this group was 0.22mm. The questionnaires applied allowed characterizing the sample of the group 1 as low income and low education in relation to the group 2, but with need of dental treatment. We concluded, therefore, there was no direct relation between the platelet count of IPT individuals when the intraoral test was performed, and their periodontal conditions received the indexes “G”, “P” e “R”.

Published: March 2017

Background: Internal anatomy of maxillary first premolars is particularly multifaceted on account of the variation in number of roots and canal configuration. Maxillary first premolars with 3 roots are called as small molar or “radiculous” because of their similar anatomy to the maxillary first molars. The most demanding step in endodontic treatment is identification and proper access to pulp canals of certain teeth with atypical canal configurations. Methods of identification of such premolars can be by various aides.Case Presentation: The present case describes the application of Cone Beam-Computed Tomography in the diagnosis of extra root with extra canal in a three rooted maxillary right first premolar.Conclusions: Proper knowledge of the anatomical variations is a must for an endodontist to make a treatment successful. Utilizing the latest technology along with the traditional concepts can surely rule out the inaccuracy in the treatment involved in such cases.

Aim: The purpose of present study is to assess the attitude of general dental practioners towards use rotary instruments and hand instruments for root canal treatment.Material and Methods: It was a cross-sectional questionnaire study conducted in the private clinics in Lucknow city, Uttar Pradesh. A total of 400 clinics were visited and face to face interview schedule was conducted. Questionnaire consists of demographic details of dental professionals. Information regarding the years of experience, OPD details and number of root canal treatment done per week by dental professionals was obtained. Use of rotary and hand instruments by dental professionals was inquired. Years of experience with Rotary instruments, procedural problems with rotary instruments faced by dental professionals and reasons for not using the rotary instruments if any was also recorded.Results: 102 (33%) of the total study samples were using rotary instruments for root canal treatment and 100 (32%) using both rotary and hand instruments for root canal treatment. Dentists who are using rotary instruments are facing the procedural problem of file breakage {70 (36%)}. And those dental professionals using hand instruments are facing the problem of ledge formation {82(40%)}.Conclusions: The main procedural failure of the rotary instruments in root canal treatment, faced by dental professionals was file breakage and with hand instrument is ledge formation. Lack of expertise is the main reason which restricts dental professionals from using rotary instruments.
