RESUMO

Aim: The aim of this study was to evaluate the gingival microleakage and internal voids in Class II composite restoration restored with precure and co-cure lining techniques using stereomicroscopic method. Materials and Methods: Forty-five freshly extracted permanent multirooted human molar teeth were collected and used in the study. After surface debridement and scaling of all teeth, standard Class II mesio-occlusal cavities were prepared. Forty-five samples were randomly divided into three experimental groups (n = 15), and filled according to manufacturer's instructions. Group I was precure group, Group II was co-cure group, and Group III was only bulk fill. The finishing and polishing of the restorations was done after 24 h. Then, all the specimens were subjected to thermocycling for 500 cycles. The gingival microleakage and internal voids of all the groups were evaluated using dye penetration method. Samples were then sectioned and examined under the stereomicroscope at ×40. Readings obtained were subjected to statistical analysis using SPSS ver 20.0 (IBM Corp, ARMONK USA) and Chi-square test. Results: The statistical analysis revealed that extent of microleakage was maximum in Group II (co-cure), followed by Group III (only bulk fill) and Group I (precure). The gingival voids were maximum in Group III (only bulk fill), minimum in Group II (co-cure), and least in Group I (precure). The cervical voids were maximum in Group II (co-cure) and Group III (only bulk fill), followed by Group I (precure). The occlusal voids were maximum in Group II (co-cure) and similar in Group I (precure) and Group III (only bulk fill). Conclusion: The precure lining technique was better than co-cure lining technique in terms of both microleakage and internal voids.

RESUMO

AIM: To assess the knowledge and perceptions of COVID-19 among pediatric dentists based on their dependent source of information. METHODS: A descriptive-analytical cross-sectional survey using a self-administered questionnaire with 23 questions was sent via Google forms to pediatric dentists. All participants were divided into three groups [postgraduate residents (PGs), private practitioners (PP), and faculty (F)]. The comparison of knowledge and perception scores was made based on occupation, source of information, and descriptive statistics used for the analysis using SPSS 21.0 (IBM, Armonk, NY, USA). RESULTS: A total of 291 pediatric dentists completed the survey, and the majority of them were females (65%). Overall, good mean scores were obtained for knowledge (9.2 ± 1.07) and perceptions (5.6 ± 1.5). The majority of the participants used health authorities (45%) to obtain updates on COVID-19, while social media (35.1%) and both (19.6%) accounted for the next two. A statistically significant difference (p < 0.05) was found among different pediatric dentists groups for relying on the source of information. CONCLUSION: Overall good pediatric dentists showed sufficient knowledge regarding COVID-19. The pediatric dentists' age, occupation, and source of information influenced knowledge regarding COVID-19, whereas perceptions were influenced by age and gender of the participants. Health authorities successfully educated pediatric dentists than the social media.

RESUMO

AIM: To analyze the comparative change in pretreatment and posttreatment La*b* values of color in initial nonpitted white spot lesions of fluorosed teeth after resin infiltration with DMG-Icon spectrophotometrically with VITA easy shade. MATERIALS AND METHODS: A total of 30 maxillary and mandibular permanent anterior teeth with mild, nonpitted white spot lesions (atleast one) of fluorosis [till grade IV of Thylstrup and Fejerskov (TF) index] in patients between 6 years and 14 years of age were included in the present study. Shade of selected tooth and its white spot lesion area was recorded using VITA 3D shade guide, both pre and postoperatively, i.e., after application of DMG Icon. This was followed by recording the change in corresponding La*b* values of tooth shade and white spot lesion spectrophotometrically using VITA Easy Shade. Results obtained were analyzed statistically. RESULTS: ΔE value of color change was found to be less than 3.7 in most of samples after resin infiltration and esthetically color change to naked eye was statistically significant (p value < 0.00001) postoperatively. CONCLUSION: Resin infiltration with DMG Icon can improve the color of non-cavitated white spot lesions. The esthetic effect of this treatment was evident immediately after treatment. Moreover, no cavitation occurred after etching, even when the surface layer had been eroded completely. CLINICAL SIGNIFICANCE: Achievement of esthetic results without loss of tooth structure and postoperative sensitivity. HOW TO CITE THIS ARTICLE: Dogra S, Goyal V, Gupta A, et al.

RESUMO

Background: The direct composite veneers follow the concept of no preparation or minimal preparation that has developed an appropriate enamel bonding procedure. The composite veneers can be easily repaired and thus they are economically favorable. The long-term clinical performance of direct composite veneers depends on a number of factors, with fracture resistance and marginal adaptation being one of the significance. Aim and Objective: The aim of the present study was to evaluate the fractural strength and marginal discrepancy of direct composite veneers using four different tooth preparation techniques (window preparation, feather preparation, bevel preparation, and incisal overlap preparation). Settings and Design: The present study is an in vitro study with the sample size of 75 participants. A total of 75 human extracted maxillary central incisors were collected and then divided into four experimental groups and one control group (n = 15 each). Materials and Methods: A total of 75 human extracted maxillary central incisors were collected and then divided into four experimental groups and one control group (n = 15 each). Four tooth preparation techniques were performed followed by direct composite veneering. All the study samples were then splitted into two equal halves. One half of all the samples was subjected to a cell load from 0 N to 100 KN at a crosshead speed of 1 mm at 90° angulation using universal testing machine to evaluate the fractural strength. The other halves were sectioned longitudinally, and the samples were then subjected under the travelling microscope at ×200 magnification to measure the marginal discrepancy at cervical, middle, and incisal locations. Statistical Analysis: The data obtained were subjected to statistical analysis using SPSS Version 20.0. Results: The fractural strength showed the maximum strength in Group V: Control group (273.33 ± 81.01), Group III: Bevel preparation (193.80 ± 66.59), Group IV: Incisal overlap preparation (188.93 ± 76.14), Group II: Feather preparation (160.33 ± 53.59), and least in Group I: Window preparation (147.74 ± 48.95). The marginal discrepancy showed maximum discrepancy in Group IV: Incisal overlap preparation (49.11 ± 6.33), Group II: Feather preparation (48.44 ± 6.01), Group III: Bevel preparation (46.67 ± 7.07), and least in Group I: Window preparation (45.33 ± 6.31). Conclusion: The fractural strength was maximum in Group V, followed by Group III, Group IV, Group II, and the least mean value score was found for the Group I, and the marginal discrepancy was maximum in Group IV, followed by Group II, Group III, and the least mean value score was found for the Group I.

RESUMO

Aim: The aim of the present study was to evaluate and compare the antimicrobial efficiency of different irrigating solutions against Enterococcus faecalis with or without the use of 980 nm diode laser in infected root canals. Materials and Methods: A total of 100 freshly extracted human single-rooted teeth were divided into three experimental groups (n = 30) and one control group (n = 10). Experimental group was subdivided into two subgroups A and B (n = 15), whereas control group was subdivided into positive and negative controls (n = 5). After access cavity preparation, the root canals were prepared using ProTaper rotary instruments. A volume of 5 ml of 5.25% sodium hypochlorite and 17% Ethylenediaminetetraacetic acid, 1.2 ml of 2% chlorhexidine gluconate, and 2 ml of neem solution was used for irrigation in Group I, II, and III, respectively. E. faecalis (ATCC 29212) was inoculated into each canal of experimental groups and incubated for 2 weeks under aerobic conditions at 37°C. In all the subgroups B, laser irradiation was performed, whereas, in subgroup A, no laser irradiation was done. In negative control, E. faecalis was not inoculated in samples, but in positive control, E. faecalis inoculation and incubation procedure was followed. With circumferential filing using #40 reamer, dentinal chips were collected using sterile paper points, vortexed in sterile saline, was then applied to UTI Hicrome agar culture plates and incubated at 37°C for 48 h. The cfu/ml for each plate was calculated using a bacterial colony counter. The data obtained were subjected to statistical analysis using SPSS software version 20.0. Results: The study showed that the least number of bacterial cfu/ml was observed in Group IB. The order of bacterial colony count (cfu/ml) was observed as Group IB

RESUMO

Background: A furcation perforation is mid-curvature opening into periodontal ligament space which is a worst possible outcome in root canal treatment. Perforations should immediately be repaired with a biocompatible material to seal the communication between perforation site and gingival sulcus. Aim: The aim of this study was to evaluate the push-out bond strength of glass ionomer cement, hydroxyapatite, mineral trioxide aggregate, and biodentine (BD) when used in repairing furcal perforations with and without blood contamination in permanent molars. Materials and Methods: A total of 120 human extracted molars were collected and divided on the basis of perforation repair materials and blood contamination status (n = 15). All the materials were subjected to universal testing machine to a load cell from 0 N to 100 KN at a crosshead speed of 1 mm/min. Statistical Analysis: The data obtained were subjected to statistical analysis using SPSS version 20.0. Results and. Conclusion: The push-out bond strength was maximum in BD contaminated with blood and least for the hydroxyapatite contaminated with blood. A significant difference was found between all the perforation repair materials.

RESUMO

Treatment of nonvital immature permanent teeth with calcium hydroxide is associated with few difficulties such as weakened tooth root, root canal reinfection, and long treatment time. Mineral trioxide aggregate (MTA) apical plug method is an alternative treatment method for open apices and has gained popularity in the recent times. This case report describes the management of a late-referral case of periapically involved, traumatized immature permanent incisor by endodontic treatment and the use of MTA apical plug. After preparing the access cavity, the working length was determined. The root canals were irrigated with 3% sodium hypochlorite and disinfected with metapex for 2 weeks. MTA was then placed in the apical 3 mm of the root canal. The remaining part of the root canal was filled with thermoplastic gutta-percha, and the coronal restoration was finished with composite resin. After 1-year follow-up, radiograph showed successful healing of periradicular radiolucency.

RESUMO

White opacities have always been a major concern of esthetics for patients and can have varying etiology. In general, white discolorations of enamel might be due to dental fluorosis, early caries (white spot lesions), developmental defects etc. Conventional treatment options available for such opacities include non-invasive and invasive approaches. Recently, a new "micro-invasive" technique has been introduced as an alternative therapeutic approach that improves such opacities esthetically, in a single sitting, is painless and exhibits no complications. This case series illustrates the use of resin infiltration to treat fluorosis stains and WSLs, exhibiting significant improvement in esthetics.

RESUMO

Cherubism, a pediatric disease, is a self limiting non-neoplastic autosomal dominant fibro-osseous disorder of jaws. It is a self limiting disease and rarely apparent before the age of two years. It occurs in children and predominantly in boys. It is characterized by clinical bilateral swelling of cheeks due to bony enlargement of jaws that give the patient a typical 'cherubic' look. Regression occurs during puberty when the disease stabilizes after the growth period leaving some facial deformity and malocclusion. Cherubism may occur in solitary cases or in many members of the family, often in multiple generations. Radiographically, lesion appears as bilateral multilocular radiolucent areas. Since it was first described by Jones in 1933, many cases have been documented. Here a case of 8 years old cherubic child, with his clinical appearance as well as radiological evaluation and discussion about clinical outcome are presented. The patient was diagnosed but not treated.
