Materials and Methods: The present retrospective study analyzed pre- and posttreatment records of a total of 60 patients. Intraoral digital photographs before and after the orthodontic treatment were used to measure the following three periodontal variables: (a) width of the keratinized gingiva, (b) gingival recession, and (c) the status of interdental papilla. The ImageJ 46 software imaging program was used to perform the required measurements. The clinical data were then analyzed in an association with the participants’ demographic data, the type of orthodontic tooth movement, and other confounding factors. The data obtained were manually entered into the statistical package and analyzed using a significance level set at P < .05. Descriptive statistics, paired t-tests, and Pearson’s correlation analysis were used to identify differences among the studied variables. Results: Among the 60 patients, the majority (66.7%) were females. Most cases of the treated malocclusion were Class II, and most patients underwent intrusion and retrusion movements. The width of keratinized gingiva increased for most sites of upper teeth. In contrast, the lower teeth showed a mix of improvement and compromised width of keratinized gingiva. As a measure of gingival recession, the difference of clinical crown height revealed the tendency toward a reduced clinical crown height for most sites. Upper left lateral incisors and canines showed significant values with regard to keratinized gingival width measurements and tooth movements such as extrusion and intrusion movements. Likewise, with regard to the clinical crown height, upper right central incisors showed significant differences when correlated with the interincisal angle, lower incisors to the mandibular plane, and upper incisors to the NA line. The upper lateral incisors also showed significant correlations to certain cephalometric measurements. Conclusions: The orthodontic treatment was found to exert a significantly positive impact on the surrounding periodontium, particularly in the upper canine areas. Likewise, various types of tooth movement were found to positively affect the periodontium.","PeriodicalId":43017,"journal":{"name":"Journal of Advanced Oral Research","volume":"84 1","pages":"296 - 303"},"PeriodicalIF":0.7,"publicationDate":"2021-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80444492","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Titanium-prepared platelet rich fibrin (T-PRF) is a third-generation platelet concentrate developed to overcome the harmful effects of silica in glass tubes and also has a longer resorption rate. The purpose of this case report is to present the effects of T-PRF applied to the bone defect that occurs after the enucleation of the radicular cyst. A significant increase in bone density was observed after eight months of follow-up. T-PRF has been shown to be effective in the treatment of bone defects.

Nanoparticles could prove to be advantageous because of their small size and increased surface area. The aim was to evaluate the effectiveness of a chitosan nanohydrogel as a periodontal regenerative material in the management of intrabony defects. Materials and Methods: Twenty patients within the age group of 30 to 60 years with intrabony defects >3 mm and clinical attachment levels >5 mm were selected. They were divided randomly into two groups: group-1, which received only open flap debridement with bone graft and acted as control, and group-2, which received open flap debridement, bone graft mixed with a chitosan nanohydrogel, and acted as the test site. Clinical and radiographic measurements were recorded at baseline, three months, and six months. Intragroup comparison was done using a paired t-test and intergroup comparison was done using an unpaired t-test with the statistical value set at P < .05. Results: Chitosan hydrogel incorporated bone grafts showed improved bone regenerative potential. The mean reduction in clinical attachment level in group-2 (8.7 ± 0.6 to 1.6 ± 0.8) was significantly higher than that of group-1 (8.6 ± 0.5 to 2.4 ± 0.7). The mean reduction in probing depths in group-2 (test group) was significantly higher (8.3 ± 0.9 to 1.6 ± 0.8) when compared to group-1 (8 ± 0.8 to 2.3 ± 0.7). Significant amount of defect fill was obtained in both the groups from baseline to six-month period.

Materials and Methods: In this cross-sectional study, a total of 60 patients (30 males and 30 females, 9 to 17 years of age) was included using randomization in strata and then divided equally (n = 15) into four groups according to the Angle classification. Photographs during frontal and lateral resting and also smiling were obtained from each patient before and after orthodontic treatment. A panel consisting 50 laypersons and 50 orthodontists was invited for the evaluation of the initial and final photos by using the visual analogue scale and a five-point scale to determine similarities and differences of their perspectives in the effects of orthodontic treatment on facial aesthetics. The data were analyzed by independent t-test, one-way analysis of variance, and Pearson’s correlation test. Results: The evaluation of facial aesthetics and treatment changes were not affected by the age and gender of the panel members (P <.05). Angle Class III patients were given lower scores by both orthodontists (P < .001) and laypersons (P < .05), but no significant differences were found between any of other classes (P >.05). Orthodontists reported greater improvement for Class III than in Class II Division 1 (P < .05) however laypersons did not notice the changes after orthodontic treatment for any of Angle classes (P >.05). Conclusion: Class III patients received lower scores for aesthetics from both panels. Laypersons may not be concerned about the effects of orthodontic treatment on facial aesthetics in patients with any Angle class. Orthodontists have seen more facial aesthetic changes after orthodontic treatment in Class III patients.","PeriodicalId":43017,"journal":{"name":"Journal of Advanced Oral Research","volume":"9 1","pages":"237 - 244"},"PeriodicalIF":0.7,"publicationDate":"2021-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73893113","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Materials and Methods: Two hundred fifty-two acrylic blocks were prepared in which cylindrical cavities of 4 × 2 mm 3 were formed. Pulp capping materials were placed in the cavities. Different adhesive systems were applied to each pulp capping material group. After applying the composite resin, the shear bond strength (SBS) values of the specimens were determined in the Instron test device. Fracture types were evaluated using a stereomicroscope and a scanning electron microscope. Data were analyzed by Shapiro–Wilk’s and Kruskal–Wallis H test. Results: There is a statistically significant difference between pulp capping materials in terms of SBS values (P < .05). Dycal’s SBS was found significantly lower than other materials, and the highest bond strength was observed in Calcimol LC material. Although there is no statistically significant difference (P > .05) between the adhesive agent groups in terms of SBS, Gluma 2 Bond showed the highest bond strength value. Conclusion: In traditional pulp capping materials such as Dycal, MTA, and Biodentine, using a two-step self-etch adhesive system can result in higher bond strength values. In resin-based TheraCal LC,, ApaCal ART, and Calcimol LC materials, it may be recommended to use a two-step etch and rinse adhesive system.","PeriodicalId":43017,"journal":{"name":"Journal of Advanced Oral Research","volume":"17 1","pages":"286 - 295"},"PeriodicalIF":0.7,"publicationDate":"2021-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83301077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study is to investigate the effects of proanthocyanidin and lycopene as pretreatment agents on the sound and caries-affected dentin surface on microtensile bond strength and microleakage. Materials and Methods: This study was designed as in vitro because of that 84 mandibular molar teeth were collected. Forty-two of the included teeth were carious teeth, while the other 42 were without caries. Sixty of them were used for microleakage and 24 for microtensile bond strength testing and scanning electron microscopy analysis. The samples were divided into six subgroups randomly according to dentin pretreatments: 5% proanthocyanidin, 5% lycopene, and no antioxidant application. After the restorative procedures, samples were attached to the microtensile tester. Samples were subjected to tensile stress in the load cell until they broke at a speed of 0.5 mm per min. Microtensile bond strength (µTBS) and microleakage test data were analyzed with two-way analysis of variance, Bonferroni correction, and Tamhane’s T2 tests. Results: Two-way variance analysis showed that dentin pretreatment applications, dentin substrate, and the interaction between these two parameters had statistically significant effects on µTBS values (P < .001). There was no difference between dentin pretreatment applications in terms of microleakage scores (P > .05). Conclusion: The application of dentin pretreatment with proanthocyanidin is a successful procedure that increases the bond strength in both dentin substrate, while pretreatment with lycopene in caries-affected dentin reduces it.","PeriodicalId":43017,"journal":{"name":"Journal of Advanced Oral Research","volume":"19 1","pages":"277 - 285"},"PeriodicalIF":0.7,"publicationDate":"2021-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81122796","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Disturbances in the neurotransmitters and their receptors in the central nervous system may play a significant role, particularly in sleep bruxism. Drugs that interfere normal secretion and function of neurotransmitters are documented to be capable of inducing bruxism. Such psychotropic drugs are being used in clinical practice chiefly for the management of mood disorders, anxiety, and depression.

Materials and Methods: A total of 160 specimens were fabricated using nanohybrid, nanofilled, flowable, and bulk-fill composites; conventional, light-curing, and low-viscosity glass ionomers; and compomers. Each material group was divided into four subgroups (n = 5) as follows: Control (C), fluoride toothpaste (FT), bromelain toothpaste (BT), and hydroxyapatite toothpaste (HT). Surface roughness values of all specimens were examined using an optical profilometer and a scanning electron microscope at 500, 1,000, and 3,500 magnifications. Results: The highest average roughness value (Ra; µm) was obtained from the conventional glass ionomer material (P < .001). While the mean Ra value was 0.155±0.116 µm at baseline, it was 0.262±0.203 µm in the fluoride group, 0.237±0.192 µm in the hydroxyapatite group, 0.260±0.293 µm in the bromelain group, and 0.198± 0.187 µm in the control group (P < .001).

Materials and Methods: A total of 200 disc-shaped samples (8 mm diameter × 4 mm depth) were prepared using four bulk-fill composites (SonicFillTM, Tetric® EvoCeram Bulk Fill, Beautifil-Bulk Restorative, FiltekTM Bulk Fill Posterior Restorative) and a microhybrid composite (FiltekTM Z250) (n = 40). Following the measurement of initial weights of the samples (m1), the surface roughness measurements were gauged using a contact-profilometer. The samples were stored in four different FSLs for 7 days, and then the second surface roughness values were recorded. The samples were stored in a desiccator to reach the constant mass and the values were recorded as m2, then the solubility levels were calculated. The Vickers microhardness values of the samples were determined. A total of 20 specimens were evaluated in terms of surface morphology with a scanning electron microscope (SEM). Data were statistically analyzed with the two-way ANOVA and Bonferroni tests (P < .05). Results: Beautifil-Bulk Restorative was affected at most in terms of surface roughness after storage in FSLs and citric acid caused the highest values in this group (P < .005). Beautifil-Bulk Restorative and Filtek Z250 showed the highest surface hardness values, while the Tetric EvoCeram group had the lowest. The highest solubility values were found in Beautifil-Bulk Restorative, and citric acid and ethanol yielded the highest solubility values for all of the composites.
