In the last few decades, research in the area of periodontology has exploded, resulting in a better understanding of risks. Latest research has expanded our knowledge about the etiopathogenesis of periodontal disease. While bacteria are needed for periodontitis to evolve, the immune system of the host is responsible for the majority of periodontal disease destruction. Newer risk components are recognized and the pattern of periodontal condition may have been affected by environmental and genetic factors. Research over the past decades has demonstrated that oral hygiene impacts the general health and course of certain systemic illness. The overall objective of research progress is therefore the prevention of disease, the analysis of the continuing disease and the treatment of existing damage.

Background Accurate prediction of the mesiodistal widths of canines and premolars in children with primary dentition facilitates interception of malocclusion at an early age. Boston University (BU) approach is one, that is, based on primary teeth for predicting canine and premolar dimensions. Aim The aim was to evaluate the size of unerupted canines and premolars using BU approach in comparison to Tanaka and Johnston (T/J) analysis in a sample of Egyptian children. Materials and Methods A total of 300 children (150 boys and 150 girls) with an average age (7–10) years with existence of primary maxillary and mandibular canines and primary first molars and eruption of all permanent mandibular incisors, free from caries, restoration or any abnormalities in size, shape or structure of teeth. The mesiodistal widths of the required teeth were measured using digital caliper from which widths of permanent canines and premolars were predicted using both T/J analysis and BU approach. Results There was a strong positive correlation between BU approach and T/J analysis when used for children in mixed dentition stage. Conclusion Application of BU approach as a prediction method of permanent teeth dimension in a sample of Egyptian children from Tanta city in the mixed dentition stage revealed a strong correlation with the widely applied T/J analysis.

Objectives This research was designed to evaluate the effect of resin infiltration material (Icon) and remineralizing agents (n-HA, CPP-ACP) on micro hardness and surface roughness of enamel white spot lesion. Materials & Methods 120 sound non carious human anterior teeth were used in this study. The teeth were divided according to the test of evaluation into two main groups. Group H: for assessment of micro hardness and group R: for assessment of surface roughness (60 teeth each).Then each group was divided into four equal subgroups (15 teeth each) according to the treatments applied as follows: subgroup(C): control, subgroup (P): CPPACP, subgroup (I): Icon and subgroup (N): n-HA. Each subgroup was further subdivided into three equal divisions (5 teeth each) according to the storage times in artificial saliva; one week (S1), four weeks (S2) and eight weeks (S3). The crowns of all teeth were separated from the roots and embedded horizontally in middle of the mould leaving the labial surface projecting using self-curing acrylic resin. Al specimens were immersed in demenaralizing solution for artificial enamel white spot lesion formation. Then treated with each respective material as follow: In subgroup (I) Icons was applied on labial surface of specimens and then immersed in artificial saliva. In subgroup (P) the labial surfaces of specimens were brushed manually by a soft toothbrush and with gentle pressure; brushing procedures were carried out three times daily with CPP–ACP- containing paste for 3 minutes then immersed in artificial saliva. In subgroup (N) specimens were immersed in 10% n-HA solution for 3min then immersed in artificial saliva and these applications were repeated daily. While subgroup (C) did not receive any surface treatment, but it immersed in artificial saliva as a positive control subgroup, artificial saliva was changed daily. For assessment of microhardness and surface roughness the enamel white spot lesion specimens in the four different subgroups were examined three times (after one week, four weeks and eight weeks from the first time of treatment application) by Vickers micro hardness testing machine and none contact profilometer. Results The results of microhardness revealed that the subgroup (N) was provided the highest micro hardness mean value, followed by subgroup (I) group, then subgroup (P) group while subgroup (C) showed the lowest micro hardness mean value.The results of surface roughness revealed that the subgroup (P) group was provided the highest surface roughness mean value, followed by subgroup (C), then subgroup (N) while subgroup (I) showed the lowest surface roughness. Conclusions Resin infiltration material (Icon) had a positive effect on microhardness and surface roughness of enamel white spot lesion.
目的研究树脂浸润材料(Icon)和再矿化剂(n-HA、CPP-ACP)对牙釉质白斑病变体显微硬度和表面粗糙度的影响。材料与方法选用120颗健全无龋的人前牙进行研究。根据评价试验将牙齿分为两大类。H组:用于显微硬度评估，R组:用于表面粗糙度评估(每组60颗)。各组按治疗方法分为4个亚组(每组15颗牙):亚组(C):对照组，亚组(P): CPPACP，亚组(I): Icon，亚组(N): N - ha。每亚组按在人工唾液中的存放次数再分为3等分(每组5颗牙);1周(S1)， 4周(S2)和8周(S3)。使用自固化丙烯酸树脂将所有牙冠与牙根分离并水平嵌入模具中间，留下唇面突出。铝标本浸泡在脱晶石溶液中形成人工牙釉质白斑。然后分别用不同的材料进行如下处理:第(一)组，在标本唇面涂上图标，然后浸入人工唾液中。亚组(P)用软毛牙刷手刷唇面，用力轻;用含CPP-ACP的牙膏刷牙，每天3次，持续3分钟，然后浸泡在人工唾液中。亚组(N)标本在10% N - ha溶液中浸泡3min，然后浸泡在人工唾液中，每日重复。而亚组(C)不进行任何表面处理，但将其浸泡在人工唾液中作为阳性对照亚组，每天更换人工唾液。采用维氏显微硬度试验机和无接触式轮廓仪对4个不同亚组的牙釉质白斑病变标本进行显微硬度和表面粗糙度的测定(分别在第一次用药后1周、4周和8周)。结果显微硬度测定结果显示，亚组(N)的显微硬度平均值最高，亚组(I)次之，亚组(P)次之，亚组(C)的显微硬度平均值最低。表面粗糙度结果显示，亚组(P)组的表面粗糙度平均值最高，其次是亚组(C)，然后是亚组(N)，而亚组(I)的表面粗糙度最低。结论树脂浸润材料(Icon)对牙釉质白斑病变体的显微硬度和表面粗糙度有积极的影响。

Persistent soft tissue enlargement in the orofacial region is often considered a feature of a chronic disease, termed as orofacial granulomatosis (OFG). Systemic diseases like crohn's, inflammatory bowel syndrome present OFG as their oral manifestation, but it may also be seen in the absence of these diseases. To the best of the authors' knowledge and literature search, this is the first case of OFG with gingival deformity related to cigarette smoking. A 25-year-old male patient presented with chief complaint of swelling on his upper lip, increase in the size of gingiva and hypersensitivity in the maxillary anterior teeth region. After thorough history of disease initiation in response to cigarette smoking, clinical examination, histopathological findings, the diagnosis of OFG associated with cigarette smoking was made. Treatment included cessation of cigarette smoking, internal bevel gingivectomy, with proper medication. Single treatment modality may not be effective in such cases. Therefore, early and precise diagnosis with sequential treatment including elimination of etiological agent, anti-inflammatory drugs or even plastic surgeries may be required for improving patient's health, appearance and comfort.

Aim This study was intended to compare syringe irrigation versus two irrigation agitation protocols [manual dynamic agitation (MDA) and passive ultrasonic irrigation] regarding postoperative pain (PP) after chemo-mechanical preparation of mandibular first molars with irreversible pulpitis and symptomatic apical periodontitis using numerical rating scale. Participants and methods Ninety patients with mandibular first molars diagnosed as symptomatic irreversible pulpitis with apical periodontitis were included in this study. Teeth were classified into three groups (n = 30) according to the final irrigation agitation protocol used. Root canals were irrigated using 5.25% sodium hypochlorite using the following protocols; group A: NaviTip (31-G 27 mm) with double side-port irrigator tip (side vented needle). Group B: MDA with well fitted master cone. Group C: ultrasonic activation using Endo ultra. PP was evaluated after 6, 12, 24, 48, and 72 h and 1 week. Level of confidence at 95% was used for statistical significance. Results Severity of PP was significantly more intense at 6–12 and 24-h time intervals in group B patients than groups A and C (P < 0.05). There was no significant difference among all groups at the other time intervals (P > 0.05). Conclusion After chemo-mechanical preparation in mandibular first molars with symptomatic irreversible pulpitis and apical periodontitis, MDA caused greater PP in comparison with the other irrigation agitation protocols in the first 24 h. Severity of PP in all groups decreased over time.

Beginning from late December 2019, this spring of 2020 has been a testing time globally for every individual. Especially impacted are the health care educators of both medical and dental communities. New coronavirus disease 2019 or severe acute respiratory syndrome-CoV-2 is a highly contagious and lethal virus that has drastically influenced students, health care teachers, patients, and clinicians similarly. Numerous dental and medical schools/colleges have temporarily put on hold all clinical postings and placements along with classroom teaching to counter this virus's transmissibility. The onset of this disease may have profound and drastic consequences as colleges and universities have begun to conduct remote assessments while few are even considering deferring fresh students' related courses due to the inability in carrying out teaching and clinical postings. As health care systems shall be further stretched with an increasing burden of new coronavirus disease 2019, disruptions in medical education are expected across all countries and continents. Hence, necessary arrangements have to be made so that learning students can maintain their clinical skills as well as knowledge. Teleteaching or remote teaching technologies can potentially substitute in-person lectures and clinical training, particularly during the current pandemic era. These replacement approaches may be necessary as effective measures in the current medical education dilemma during this current health care crisis and shall also aid in laying the future foundation for teaching during similar confounding situations. In this review article, we shall discuss various modes of remote teaching that are available at this time.

Settings and design The study was conducted as a clinical trial. The clinical part was carried out at Pediatric Dentistry Department, Faculty of Dentistry, Tanta University and the laboratory work was carried out at Biochemistry Department, Faculty of Medicine, Tanta University. Patients and methods Sixty children of both sexes aged between 5 and 8 years old were included in the study. The selected children were divided into two groups; group 1 included 30 children received stainless steel crowns and group 2 included 30 children received band and loop space maintainers. Salivary and urinary samples were collected from the participating children at the beginning of the study and then after 1 week, 2 weeks, 1 month, 3 months, 6 months and 9 months of receiving the appliances. The samples were prepared and analyzed for measuring nickel and chromium ions release using inductively coupled plasma optical emission spectrometry. Statistical analysis used All test statistics were performed using the SPSS software statistical package and the significance was set at P value less than or equal to 0.001. Results Salivary metal ions release reached its peak on the first week then diminished with time and urinary release increased on the first week, nearly remained stable till the first month then it decreased with time. Ions levels were higher in urine than in saliva with statistically significant differences. The release is slightly higher in group 2 but without statistically significant differences between both groups. Conclusions The maximum levels of released ions were significantly below their average dietary intake levels and did not reach their upper tolerable intake levels.

Aim To evaluate the clinical performance of two glass ionomer restorative materials (EQUIA Forte Fil and IonoStar Molar) and a nanohybrid composite (Tetric EvoCeram) in class I cavities over 1 year. Patients and methods Twenty patients of age 25–40 years received 60 restorations. Each patient received three different restorations representing the tested materials. Class I cavity was prepared according to the caries extension. All the materials were applied following the manufacturer's instructions. Finishing and polishing was performed using finishing burs and polishing discs. Each restoration was evaluated clinically at baseline (24 h), 6 months and after 1 year using modified USPHS. Results The recall rate was 100% after 1 year. The alpha rating for retention and restoration fracture for EQUIA Forte Fil were 95%, IonoStar Molar 85%, Tetric EvoCeram 100% alpha ratings. For marginal discoloration for EQUIA Forte Fil were 95%, IonoStar Molar 80%, Tetric EvoCeram 95% alpha ratings. For marginal adaptation for EQUIA Forte Fil were 90%, IonoStar Molar 80%, Tetric EvoCeram 90% alpha ratings. For anatomic form for EQUIA Forte Fil 95%, IonoStar Molar 75%, Tetric EvoCeram 95% alpha ratings. For color match for EQUIA Forte Fil 85%, IonoStar Molar 80%, Tetric EvoCeram 90% alpha ratings. For surface texture for EQUIA Forte Fil 85%, IonoStar Molar 90%, Tetric EvoCeram 95% alpha ratings. For secondary caries for EQUIA Forte Fil 95%, IonoStar Molar 85%, Tetric EvoCeram 100% alpha ratings. Using χ2 test, there was no statistically significant difference between the tested groups for marginal discoloration, marginal adaptation, anatomic form, color match, and surface texture (P<0.05). Conclusion EQUIA Forte Fil Glass ionomer achieved clinically superior results after 1 year of service. IonoStar Molar Glass ionomer also achieved acceptable results.

Patients and methods Twenty patients of age 25–40 years received 60 restorations. Each patient received three different restorations representing the tested materials. Class I cavity was prepared according to the caries extension. All the materials were applied following the manufacturer's instructions. Finishing and polishing was performed using finishing burs and polishing discs. Each restoration was evaluated clinically at baseline (24 h), 6 months and after 1 year using modified USPHS. Results The recall rate was 100% after 1 year. The alpha rating for retention and restoration fracture for EQUIA Forte Fil were 95%, IonoStar Molar 85%, Tetric EvoCeram 100% alpha ratings. For marginal discoloration for EQUIA Forte Fil were 95%, IonoStar Molar 80%, Tetric EvoCeram 95% alpha ratings. For marginal adaptation for EQUIA Forte Fil were 90%, IonoStar Molar 80%, Tetric EvoCeram 90% alpha ratings. For anatomic form for EQUIA Forte Fil 95%, IonoStar Molar 75%, Tetric EvoCeram 95% alpha ratings. For color match for EQUIA Forte Fil 85%, IonoStar Molar 80%, Tetric EvoCeram 90% alpha ratings. For surface texture for EQUIA Forte Fil 85%, IonoStar Molar 90%, Tetric EvoCeram 95% alpha ratings. For secondary caries for EQUIA Forte Fil 95%, IonoStar Molar 85%, Tetric EvoCeram 100% alpha ratings. Using χ2 test, there was no statistically significant difference between the tested groups for marginal discoloration, marginal adaptation, anatomic form, color match, and surface texture (P<0.05). Conclusion EQUIA Forte Fil Glass ionomer achieved clinically superior results after 1 year of service. IonoStar Molar Glass ionomer also achieved acceptable results. Tetric EvoCeram composite achieved superior clinical results for all criteria of the evaluation. A longer evaluation period may be recommended to decide the use of these materials safely in class I cavities.","PeriodicalId":22324,"journal":{"name":"Tanta Dental Journal","volume":"34 1","pages":"49 - 59"},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80807095","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}
Aim The aim of the study was to evaluate the effect of different two mouthrinses and repolishing on the color stability of hybrid nanoceramic computer-aided design/computer-aided manufacturing (CAD/CAM) material. Materials and Methods Thirty specimens with dimensions of 1.5 × 12 × 12 mm3 were prepared from Cerasmart CAD/CAM blocks and divided into three groups according to the immersion solutions; distilled water, Oral B, and 0.12% chlorhexidine gluconate (CHX) for 2 min, twice for a day. Initial, 7th day, 14th day, and following repolishing color values were measured with a dental spectrophotometer according to the CIELab system and color changes were calculated (ΔE). Data were statistically analyzed with the Kruskal–Wallis test. Results Oral B and CHX groups showed significantly higher ΔE values than control groups (P ≤ 0.05). No significant differences were found between Oral B and CHX in both ΔE measurements (P ≥ 0.05). There were no significant differences among the 7th day, 14th day, and after repolishing color changes in control and CHX groups (P ≥ 0.05). However, color change after repolishing was significantly less than the 14th day color change (P ≤ 0.05). Conclusions Oral B and CHX caused discoloration on the CAD/CAM restorative material in clinically acceptable limits. Repolishing could provide a significant change only after 14 days of use Oral B.

The use of various hard tissue cutting instruments like micromotors and carbide burs pose a certain disadvantage such as excessive heat generation, smear layer formation, difficulty in controlling the bleeding of the operating field, etc. These disadvantages not only increase the intraoperative time but also affects the overall prognosis of the treatment. At present, the use of power ultrasonics has gained popularity over conventional techniques for procedures involving hard tissues. It overcomes the various disadvantages of traditional instruments as well as provides increased precision, protection of both soft and hard tissues as well as hastens the healing after osseous surgeries. The present review article aims to highlight the impact created by the piezoelectric devices in various dental procedures, specifically periodontal and implant related therapies, its mechanism of action and the advantages over conventional osseous surgeries.
