objective: In Class I, Class II, and Class III cases, disc and condylar locations, as well as joint spaces were evaluated and compared. The goal of this study was to see how likely the three groups were to develop temporomandibular disorders (TMDs). Materials and Methods: Certain inclusion and exclusion criteria were used to select a sample of 90 cases, with 30 cases in each of the three classes (Class I, Class II, and Class III). In the sagittal plane, magnetic resonance imaging (MRI) was used to study the location of the articular disc, condyle, and joint spaces using a closed mouth approach. Results: The morphology of the temporomandibular joint (TMJ) was altered in both Class II and Class III patients, with the greatest disparity in Class II patients. In Class II patients, MRI revealed a tendency for anterior disc displacement with condyles positioned more anteriorly. In the Class III patients, the disparity was smaller. Conclusions: Class II patients are more likely to develop TMDs and it is advised to evaluate the TMJ before beginning orthodontic treatment to identify and stop an asymptomatic TMD from progressing to a more severe form.

ABSTRACT

Aim: The aim of this study was to assess clinically and radiographically the efficacy of the socket shield technique in maintaining facial contours and crestal bone after immediate implant placement, combined with PRF application.

Subject and Methods: Sixteens patients with 16 implants were divided into two groups, Group “1”: 8 Patients were subjected to socket shield procedure combined with immediate implant placement alone. Group “2”: 8 Patients were subject to socket Shield technique and immediate implant placement combined with PRF application. Clinical parameters were gathered at baseline, 6-, and 12-months post-operative.

Results: There was a statistically significant difference between (Group 1) and (Group 2) in (mSGI), There was a statistically significant difference between (Group 1) and (Group 2) at 6 months in implant stability, and there was a statistically significant difference between both groups at 6 months in peri-implant pocket depth, there was no statistically significant difference between (Group 1) and (Group 2) in modified plaque index. Also, there was no statistically significant difference between (Group 1) and (Group 2) at different periods in bone density, In addition, There was a statistically significant difference between (Group 1) and (Group 2) groups at 12 months in (MBL). While there was no statistically significant difference between (Baseline), (6m), and (12m) between the two groups in labial bone thickness.

Conclusion: The socket shield technique with or without PRF application was shown to be effective to achieve osseointegration without any inflammatory response. Using PRF with socket shield and immediate dental implants exhibited to be superior to immediate dental implants with socket shield alone in improving peri-implant conditions and dental implants.

Aim: Coronavirus disease (COVID-19) was first to appear in Wuhan, China, in 2019. Being highly contagious, it started to spread rapidly throughout the entire world causing fear and anxiety among all nations with a very high mortality rate. Dentists are considered at an extremely substantial risk to be infected among all health care workers because they are working in close contact with their patients and also because of being regularly exposed to the aerosols, droplets and saliva splashing out of the patients’ mouth. Subjects and Methods: This study was based on a questionnaire to assess the knowledge of the graduating dental students about the signs and symptoms of (COVID-19) infection and also to evaluate their awareness about the precautions and infection control measures required during the dental treatment to keep them safe and control the spread of the disease. A well-constructed and validated questionnaire was formed and its link was sent to dental students in all year grades at different universities in Upper Egypt. The data were collected, tabulated, and statistically analyzed by SPSS (Statistical Package for Social Sciences). Results: Result showed significant valued regarding that the dental students have a good understanding of COVID-19 and the precautions. Conclusion: As a result, it was concluded that the dental students have a good understanding of COVID-19 and the precautions that must be taken to provide adequate dental treatment for patients during the pandemic.

The aim of this study is to evaluate the efficacy of the use of superior repositioning splints in the management of Temporomandibular Joint Anterior Disc Displacement with Reduction cases in a one-year follow-up. The study included 60 patients who were selected from the TMJ outpatient clinic of the Oral and Maxillofacial Surgery Department, Faculty of Dentistry, Assiut University and all were treated with a superior repositioning splint. The entire sample was examined using unassisted mouth opening and the Visual Analogue Scale (VAS). The records were taken at three time points, pre-treatment (before using the splint), after 6 months and after 12 months of using the splint. There was a considerable significant improvement in the visual analogue scale report and the range of unassisted mouth opening. It was concluded that the use of superior repositioning splints is an effective strategy in the treatment of Temporomandibular Joint Anterior Disc Displacement with Reduction.

Background: Bone grafting of the cleft maxilla before eruption of the permanent cuspid has become an accepted part of the management of patients with clefts involving the maxillary alveolus. The reasons for performing a bone graft are to stabilize the maxillary segments and provide bony support for the teeth adjacent to the cleft. Objective: The aim of the present study is clinical and radiographic evaluation of the outcome and efficacy of sticky bone (mixture of autologous fibrin glue (AFG) and bovine bone graft) as a bone substitute for the treatment of alveolar cleft. Patients and Methods: 41 patients with a total of 58 alveolar clefts, 17 bilateral and 24 unilateral clefts, treated by alveolar bone grafts using sticky bone. Their age ranged from 6 to 18 years with a mean of 11.6. The follow-up was up to one year. Results: From a total number of 58 alveolar clefts. Adequate healing was resented in 47 of them [30 of them were class I (51.7%) and 17 were class II (17%)]. Inadequate bone healing occurred in 11 clefts [6 of them were class III (10.3%) and 5 were class IV (8.6%)]. Conclusions: Bone grafting of alveolar clefts is a mandatory step in the management of cleft lip and palate patients, sticky bone could be considered as promising and effective bony substitute and could be used efficiently for the treatment of cleft alveolus as an alternative to autogenous bone grafts to avoid harvesting bone of the patient and its complications and the earlier the grafting producers are done, the better quality of grafted bone.

Background: Post-operative nursing protocol for patients with partially edentulous has a vital role in improving oral health status and increase dental implant success rate. The current study aimed to evaluate the effect of postoperative nursing protocol on oral health status and dental implant success among patients with partially edentulous. Research design: Posttest only nonequivalent groups design was used to utilize this study. Setting: The study conducted at the outpatient clinics in the Oral& Maxillofacial Surgery Department at Assuit University Dental Hospital. Sample: 40 Dental implant in partially edentulous patients. Tools: Tool (I): Oral& maxillofacial interview assessment questionnaire. Tool (2): Observation check list for dental implant care. Tool (3): Probing depth scale. Tool (4): Pain assessment scale (VAS). Results: Two thirds of the patients in the study group were female, according to this study with age range from 30 > 40yrs old and showed significant decrease in average probing depths& demonstrated significant reduction in pain intensity when compared to the control group. In addition, all implant stability in both groups were stable. Conclusion: Implementation of post-operative nursing protocol among patients with partial edentulous showed an improvement on their oral health status and increase dental implant success rate. Recommendation: Continuous implementation of post-operative nursing protocol to upgrade dental implant success rate among patients with partial edentulous. As well encourage nurses to upgrade their information regarding dental care and to get dental nursing diploma or other academic dental nursing degree.
