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.","PeriodicalId":22324,"journal":{"name":"Tanta Dental Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88577557","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}

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.

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.","PeriodicalId":22324,"journal":{"name":"Tanta Dental Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91422898","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}

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.","PeriodicalId":22324,"journal":{"name":"Tanta Dental Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87867355","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}

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).

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.","PeriodicalId":22324,"journal":{"name":"Tanta Dental Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75720234","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}
