The mucosa of body is formed from the first pharyngeal arch and third pharyngeal arches; while the skeletal muscles develop from myoblast that migrate from occipital somite's. Aim Owing to its effect on the building structures all around and vital functions, this study was carried out to assess the tongue posture in vertical malrelations; in class I malocclusion. Materials and methods A cephalometric study was carried out on 153 adult patients (76 female, 75 male) from 17 to 22 years old) with skeletal class I. The sample was selected according to the mandibular plane angle (SN/GO-GN) and categorized according to vertical facial pattern into; high angle (SN/MP >37), low angle (SN/MP <27) and average angle (SN/MP 32 ± 5°); including 26 females and 25 males in each group. The tongue position was calculated along horizontal line passing through the incisal edge of the lower central incisor to the cervical distal third of the lower second molar and extending posteriorly. Taking the cervical area as a center, six angles will be drawn at 0°, 30°, 60°, 90°, 12°, and 150°. The contours of the dorsum of the tongue and the palate and six distances will be measured at 0°, 30°, 60°, 90°, 120°, and 150° between tongue and palate contour. Results Tongue positions were found to be higher in position in skeletal class I malocclusion in low and high mandibular plane (posterior part of the tongue); on the other, lower tongue position (anterior part) was found in increased mandibular plane angle without sex differences Conclusion Tongue position is affected by the position of the mandible in vertical plane; regarding the anterior or posterior part without sex differences.","PeriodicalId":22324,"journal":{"name":"Tanta Dental Journal","volume":"67 1","pages":"105 - 110"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89640726","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 Forty extracted human premolars with simple occlusal caries were used. The teeth were fixed with sticky wax to the base of plastic cylinder. The cylinder was filled with self-curing acrylic resin so that only root was embedded within the self-curing acrylic resin. The teeth were randomly divided into two main groups (n = 20) according to the preparation technique. Group I: class I cavity preparation was done by the conventional drill method using a #245 Carbide bur and contra angle high-speed hand piece with water coolant. Cavity design was restricted to remove caries with no undercuts, and no beveling. Group II: class I cavity preparation was done by Aquacut Quattro air hydro-abrasion unit which uses a gamma irradiated aluminum oxide particle as abrasives (29 μm), cutting fluid and a hand piece of 0.6 mm diameter tip. The preparation in both groups was restored by the same composite resin (Grandio) and adhesive systems (Futurabond U) following the manufacturer's instructions. All specimens were thermocycled. Impressions for each tooth was made using a polyvinyl Siloxane material. The impressions were then poured with epoxy resin. These replicas were examined under scanning electron microscope. Scanning electron microscope photographs of tested samples were used for the gap evaluation. Results It was found that, group I recorded higher mean value of marginal gap length (157.57 ± 35.15 μm) than group II that recorded (69.55 ± 20.02 μm). Also, group I recorded higher mean value of marginal gap length ratio (10.72 ± 2.47) than group II that recorded (7.44 ± 2.69). Conclusion Conventional drilling technique was faster than the hydro-abrasion technique for cavity preparation. Hydro-abrasion technique showed more marginal adaptation than conventional drilling technique.","PeriodicalId":22324,"journal":{"name":"Tanta Dental Journal","volume":"86 1","pages":"12 - 19"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79409740","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}

Methods Thirty-six teeth samples were artificially demineralized. The samples were randomly assigned to two groups: group 1: teeth restored with resin infiltration material (Icon) and group 2: teeth pretreated with GSE gel before resin infiltration with Icon. A scanning electron microscope was used to examine teeth samples before and after demineralization and after restoration. Energy dispersive radiograph analysis was employed to analyze the calcium and phosphorus weight percent of samples before and after restoration to detect remineralization. Both groups were subjected to a hardness test using a Vickers microhardness tester. Color change after the restoration of the two groups was detected using a spectrophotometer after 1 day and 1 month of immersion in deionized water. Results Group 2 exhibited occlusion of defect microporosity with a more uniform surface compared to group 1. Group 2 had significantly higher calcium weight %. Both groups showed significant improvement in hardness but a nonsignificant mean difference between the two groups. Color change after 1 day and 1 month were significant for both groups but ΔE values after 1 month are within the clinically acceptable range for a color change compared to intact enamel.

Materials and methods 30 intact, noncarious freshly extracted human premolars, were collected, cleaned from all soft debris and/or calculus and polished using prophy polishing paste. Each tooth was sectioned first at cement enamel junction (CEJ) to separate crown after removal of root. Each crown was mesiodistally sectioned to a thickness of 1–2 mm then stored in artificial saliva which was periodically changed. All the specimens were exposed to demineralizing solution at occlusal surface only (the surface of the study) for creation of enamel lesions. All the specimens were examined with, EDX and tested under PLM to evaluate enamel surface. After demineralization the specimens were divided randomly into three equal groups I, II and III consist of 10 specimens of each group. For group I Ozonized olive oil gel was used alone on occlusal surface for 1 min once daily, group II was treated as group I followed by application of 5% nanohydroxyapatite paste, while all specimens in group III were treated as group I followed by fluoride gel application. All the procedures at the three groups were repeated daily for 21 days.

Methods This was prospective randomized noncontrolled clinical study that was carried out on eight adult patients suffering from chin deformities as a result of unilateral temporomandibular joint ankylosis. Patients were selected from the outpatient clinic, Department of Oral and Maxillofacial surgery, Faculty of Dentistry, Tanta University. All cases were operated for genioplasty under general anesthesia. The incision was performed on the alveolar mucosa apical to the attached gingiva by 0.5 cm in two planes (mucosal and muscular), The cutting guide was seated to the mandibular dentition, the eight screw holes were then drilled, the cutting guide was temporarily fixed on the mandible by mini screws, once the osteotomy plane was marked by a surgical saw, the cutting guide was removed, osteotomy completed routinely and the customized reposition plates were installed to reposition the chin segment as planned. Finally, after the screws were placed and tightened, the chin segment was automatically moved to its final planned position and secured. Closure was done in two layers (the muscle layer followed by the mucosa). Results Genioplasty procedure using customized surgical guide and repositioning plates was performed in every case. Postoperative recovery was satisfactory for all patients. There were no intraoperative or postoperative complications, except self-limiting edema and some small hematomas with no clinical significance. Postoperative pain intensity measured by the Visual Analog Scale was acceptable for all patients. All cases reported full recovery from neurosensory disturbance after three months follow-up periods. Regarding patients' satisfaction, all the cases were very satisfied (grade I) with a percentage of 100% on the third month postoperatively. Conclusion The results obtained from this study show that using customized surgical guide and repositioning plates in performing genioplasty had advantages over conventional technique as they provided greater accuracy, safety, less complication during the surgery with decrease in surgery time, and made the results of genioplasty procedure more predictable. So, using customized surgical guide and repositioning plates simplified the genioplasty procedure.","PeriodicalId":22324,"journal":{"name":"Tanta Dental Journal","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135494627","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}

Methods 40 extracted human mandibular first molars were collected for the study. The teeth were mounted in acrylic blocks using a dental surveyor. All teeth were endodontically treated and prepared for endocrown restorations. All samples were divided into two groups according to the material used (n = 20): group (a) for lithium disilicate glass-ceramic (IPS e.max press) and group (b) for zirconia-reinforced lithium silicate glass ceramic (VITA Ambria). Specimens of each group were subdivided into two subgroups (n = 10): subgroup (1) for assessment of fracture resistance and subgroup (2) for assessment of marginal and internal adaptation. Waxing up all teeth was done using CAD/CAM technology. Endocrowns were fabricated with the heat press method. Bonded endocrown specimens were stored at 37°C and 100% humidity for 24 h in an incubator before testing. The fracture resistance of samples was tested using a universal testing machine. Marginal adaptation and internal adaptation were assessed using a SEM. Quantities variables were expressed as mean and standard deviation using one-way analysis of variance (ANOVA) followed by Tukey's post hoc test at (a = 0.05). Results The Vita Ambria mean values (2174.99 N±537.65) had more compressive strength than IPS e.max press mean values (1974.33 N±566.35). Considering the marginal adaptation test using SEM, there was no significant difference between both materials (P = 0.656) and there was also no significant difference between either of the materials (P = 0.855) after the internal adaptation test using SEM.
