Aesthetic and functional rehabilitation in a patient with anterior skeletal open bite using lithium dissilicate glass-reinforced ceramic: a case report

The aim of this clinical report is to present the replacement of unsatisfactory metal-ceramic crowns of elements 12, 11, 21 and 22, by lithium disilicate glass-reinforced ceramic crowns in a patient with skeletal anterior open bite. A patient sought care at the Dental Hospital at the School of Dentistry of UFU, complaining of odor between the metal-ceramic crowns of the antero-superior teeth. After clinical and radiographic examination, invasion of the biological space was noticed, surgery was indicated in order to restore the biological space. After healing, the pre-existing cast metal posts were masked using an opaque composite resin and the teeth were reprepared for full all-ceramic crowns. Impressions were taken in two steps, using PVS associated to retraction cords. The ceramic copings were obtained in lithium disilicate ceramic, and the veneering was performed by stratification. After testing the ceramics crowns in relation to, fit, function and aesthetic results, cementation was completed using modified absolute isolation, followed by prophylaxis of preparations with pumice and saline, surface treatment of the ceramic restorations and luting using self-adhesive resin cement. Finally, an occlusal splint was produced to control the effects of bruxism and orofacial pain symptoms. The anterior open skeletal bite was a challenging factor for the rehabilitation of this patient; however, one must consider the entire process that the patient would undergo if choosing for orthognathic surgery, and the patient should be aware of the case limitations. In addition, the use of lithium disilicate glass-reinforced ceramics proved the versatility of this material for anterior aesthetic restorations.

Prevalence of Dental Caries, its Associated Risk Factors and Treatment Needs among School Aged Children at Kimironko II Primary School, Kigali, Rwanda

BackgroundDental caries is still a health problem worldwide, its prevalence and incidence are associated with various factors like age, sex, social status, dietary patterns and oral hygiene habits.MethodologyA Secondary data collected from outreaches done by UR CMHS, School of Dentistry at Kimironko II Primary School was analyzed. This secondary data had been obtained using structured questionnaires with close ended questions. Clinical examination had also been done to gather information. SPSS statistical software package version 22 was used to analyse data from Community outreach done at Kimironko Primary School in August 2019.ResultsThe prevalence of dental caries of 42.4% was found among children aged 6-12 years old of Kimironko II Primary School. The researchers found the following to be statistically significantly associated with prevalence of dental caries: gender (p=0.042), dental visits (p=0.001), and use of chew sticks or miswaks (p=0.041). Females were 1.4 times more likely to develop dental caries (OR: 1.462; 95% CI: 1.16-2.017; p=0.021) and children who did not use toothpick were 2 times more likely to develop dental caries (OR: 2.149; 95%CI: 1.251-4.395; p=0.036), whereas visiting a dental practitioner was protective against dental caries (OR: 0.362, 95% CI: 0.251-0.516; p=0.001).ConclusionDental caries is prevalent among children of Kimironko II Primary School. Appropriate preventive measures should be taken to protect those found to be exposed.Rwanda J Med Health Sci 2021;4(3):341-346

A Qualitative Look at Faculty Perspectives on Ergonomics in Dental Education

Due to the high-risk nature of musculoskeletal disorder development in dentistry, ergonomic education and evaluation are needed in predoctoral programs. The purpose of this pilot study is to investigate perceptions of ergonomics within the School of Dentistry (SOD), current ergonomic clinical practices among third- and fourth-year dental students, and dental students' level of knowledge of ergonomics. The study was conducted utilizing an explanatory sequential mixed methods design to collect both quantitative and qualitative data. While the data collection occurred in three phases, this article will primarily focus on Phase III. The three phases of data collection were: Phase I consisted of a questionnaire distributed to all dental students; Phase II consisted of clinical observations of third- and fourth-year dental students' ergonomic postures during patient care, and Phase III consisted of SOD faculty focus groups to determine perceptions of ergonomic education with the predoctoral curriculum. Data revealed three overarching themes: (1) Didactic to clinical disconnect, (2) Elective impacts, and (3) A ready commitment. Phase I yielded a response rate of 84% (n=135). Phase I responses noted that 81.5% (n=110) of the dental students reported experiencing musculoskeletal pain. Ninety-three dental students reported receiving one or two lectures on ergonomics; however, 60% (n=27) failed to implement proper ergonomic postures while caring for patients in the clinical environment during Phase II. Phase III, revealed faculty support of ergonomic evaluation and correction among dental students. The results indicated a need to establish and implement an ergonomic evaluation and corrective program within the SOD

Patients Satisfaction With The Dental Treatment Provided At The University of Jordan Students Clinics

Objectives: To assess patients' satisfaction with the dental care provided to them by the undergraduate students at Jordan University Hospital. Methods: The Dental Satisfaction Questionnaire (DSQ) developed by the RAND Corporation was used to measure patient satisfaction. The questionnaire was translated to Arabic the native language of the country and it consisted of 14 questions, which measure the overall satisfaction and the subscales of access, convenience & availability, continuity of treatment, and quality of dental care provided.Results: A total of 94 patients (58.5% female, 41.5% male) answered the DSQ, the Overall Dental Satisfaction Index (DSI) was found to be 86.2%, and there was no correlation between gender or age groups with the DSI (P<0.05). The lowest score (3.7/5) was given to the question about whether the school building and dental units being modern and well equipped. Conclusions: Patients who were treated at the student clinics at the University of Jordan, School of Dentistry were mostly satisfied about the treatment provided, the main cause for dissatisfaction was the clinics building that is very old and crowded, and the lack of modern dental units and equipment.

Assessment of Skeletal Discrepancies by Determining R Angle in Lateral Cephalograms in Navi Mumbai Population

There is considerable interest in the area of orthodontics in malocclusions caused by vertical discrepancies because of their causes, diagnosis, treatment planning, and tendency to return after treatment. Hence, this study aimed to assess, evaluate and check reliability for vertical skeletal discrepancy by establishing a parameter ‘R angle’ in Navi Mumbai population. In this study, the lateral cephalometric radiographs of 135 orthodontic patients between the age group of 18-30 years of age were selected from the database of the Department of Orthodontics and Dentofacial Orthopaedics in D Y Patil University School of Dentistry, Navi Mumbai The study found that the R angle is clinically and statistically important when examining vertical skeletal discrepancies. So with the above results it is observed that R angle can be used to assess vertical skeletal discrepancy in Navi Mumbai population. Along with other parameters it can be important and valuable tool for orthodontist to determine skeletal discrepancies in vertical plane.

Dysplasia in Papilloma at the Tip of the Tongue; A Rare Entity-Importance of on Time Prevention

Background: Oral papilloma is benign lesion while there is concern about high-risk types of Human Papilloma Virus (HPV) for cancer. Case Presentation: The patient was a 30-year-old woman who presented to the School of Dentistry, Semnan University of Medical Sciences for orthodontic treatment. Intraoral examinations revealed a prominent white papule on the tip of the tongue. Histopathologic exanimation revealed the proliferation of hyper keratinized stratified squamous epithelium arranged in projections with fibrovascular connective tissue cores, cell irregularity with hyperchromatic nucleus and koilocytes within the epithelium which confirmed the diagnosis of squamous papilloma (SP) with mild to moderate dysplasia. The patient was instructed to take care of the sexual behaviors and the injection of Gardasil vaccine was recommended. A month later, there was no evidence of a lesion. Conclusion: Though SPs are common lesions in the oral cavity, occurrence of dysplasia on SPs on the anterior part of the mouth is rare. Surgical removal supplemented by administration of Gardasil vaccine can be the treatment of choice in these cases. The significance of close attention to the oral lesions and consultation with an Oral and Maxillofacial Medicine Specialist is highly recommended in order to accurate diagnosis and timely treatment.

Use of a Knowledge-Based Governance Approach to Plan a Post-COVID-19 Predoctoral Dental

COVID-19 abruptly changed dental education, forcing educators out of their comfort zones and into using new technologies and teaching approaches. At the University of Washington School of Dentistry, a task force evaluated the curricular changes that resulted from COVID and made recommendations for the future predoctoral dental curriculum. This manuscript reports the process employed, the findings of the task force, and how these findings will impact the curriculum. A knowledge-based governance (KBG) approach was employed. KBG focuses on gathering all relevant information and identifying all choices. It separates dialogue from deliberation. Information was gathered via literature review, focus group interviews, electronic surveys, and other metrics. The task force evaluated: (1) delivering didactic content remotely; (2) administering assessments remotely; (3) duplicating preclinical simulation lab courses due to social distancing; and (4) the conversion from a numerical to a credit/no credit grading scale. Key recommendations resulted from focus groups and electronic surveys that allowed any student or faculty member an opportunity to provide input. Some topics were relatively non-controversial and strong recommendations were evident. The most controversial issue was which grading scale should be utilized. A KBG approach is an effective means to address mega issues in the dental school environment.

Well-Being and General Anxiety Among University of Michigan Dental Students

BackgroundAnxiety is one of the most prevalent mental health conditions, affecting approximately 1 in 9 people worldwide. More specifically, dental students have been considered vulnerable to anxiety despite the fact that dental students have also reported high levels of well-being. Therefore, we hypothesize that University of Michigan School of Dentistry (UMSOD) dental students pose high levels of well-being but suffer from anxiety. Our objective is to measure anxiety and well-being levels among UMSOD dental students for 2 consecutive academic years.MethodsDental students (N = 609) were surveyed for well-being and general anxiety levels. To assess well-being and anxiety levels we used the World Health Organization–Five Well-Being Index (WHO-5) questionnaire and the General Anxiety Disorder 7-item (GAD-7) scale, respectively. Surveys were sent through Qualtrics. For statistical analysis, chi-square and t test were used at p &lt; 0.05.ResultsThe mean well-being score among dental students was 12.26 (SD = 1.14). In the first survey moment for anxiety, which coincided with the week before the spring break in 2017, approximately 39% of the respondents (n = 255) scored 10 or higher on the GAD-7, which means moderate anxiety. In the second survey moment, the week after the spring break week in 2017, we found a slight but not significant reduction in anxiety levels, with approximately 32% of the responses (n = 109) of the dental students scoring 10 or higher on the GAD-7. Incoming first-year dental students before starting the dental school program presented well-being mean of 18 (SD = 0.60). Only 13% of incoming first-year dental students scored 10 or higher on anxiety before starting the school program. By the fall term, the well-being mean among incoming first-year dental students dropped to 13.29 (SD = 1.32), and 22% of the incoming first-year dental students scored 10 or higher in the GAD-7.ConclusionsUniversity of Michigan School of Dentistry dental students posed poor well-being and moderate anxiety. Incoming first-year dental students posed higher well-being and lower anxiety levels before starting the dental education program. However, as the academic year developed, incoming first-year dental students suffered a decrease in well-being and an increase in anxiety levels. Our study indicates a trend of poor well-being and high anxiety among UMSOD dental students.

Oral soft-tissue sarcomas diagnosed in an oral pathology service: a 16year experience

Objective: This study analyzed the prevalence and clinic-pathological features of soft-tissue sarcomas diagnosed in a single-center of oral pathology from a School of Dentistry in Brazil. Materials and methods: All consecutive cases of intra-oral soft-tissue sarcomas diagnosed between January of 2002 and December of 2018 were retrieved from the files; patient data (sex, age and race) and characteristics of the lesions (site, size, clinical aspect and duration of injury) were collected. Results: Among a total of 62,255 biopsies diagnosed in the studied period, soft-tissue oral sarcomas comprised 76 cases (0.12%). Kaposi sarcoma, rhabdomyosarcoma, leiomyosarcoma encompassed 64.5% of the cases, and 53% of these were diagnosed as Kaposi Sarcoma. Male patients were more affected (59.2%) and white patients comprised 50%. In general, 39.4% of the patients were between 21-40yo. Conclusion: Soft-tissue sarcomas are rare in oral soft-tissue and in our pathology service, they comprised only 0.12% of all diseases diagnosed in the studied period. Kaposi sarcoma was the most frequent, followed by leiomyosarcoma and rhabdomyosarcoma. Thus, it is important for stomatologists and pathologists to be aware of their characteristics when examining oral mucosa, mainly their peculiarities regarding patient’s age, clinical appearance, and site of occurrence.

Prosthetic rehabilitation of a hypohidrotic ectodermal dysplasia patient: A case report

Aim: Ectodermal dysplasia is a rare hereditary disease that arises from a developmental disorder of 2 or more ectoderm-derived tissues. Ectodermal dysplasia is seen in 3 different types: anhidrotic, hypohidrotic, and hidrotic. Its anhidrotic and hypohidrotic types are the most common. This study presents the intraoral findings and dental treatment approach of a case diagnosed with hidrotic ectodermal dysplasia that demonstrates the typical characteristics of the disease, such as anodontia, hypohydrosis (reduced sweating), hypotrichosis (sparse hair), and loss of vertical dimension. Methodology: A 5-year-old male patient presented to the clinic of the Prosthetic Dental Treatment Department of the School of Dentistry at Dicle University on 25.10.2020 with complaint of missing teeth. A genetic analysis conducted in 2016 showed that he was a homozygous carrier of the p.Cys148Arg (c.442 T>C) mutation on the 5th exon of the ectodysplasin-A receptor (EDAR) gene. The mutation detected in the patient was associated with ectodermal dysplasia. An extraoral clinical examination revealed sparse hair, eyebrows, and eyelashes; soft, smooth, and dry skin; thin, linear wrinkles around the eyes and the lips; drooping, thickened lips; a sunken nose; fractured nails; hyperthermia due to lack of sweat glands; hyperkeratosis in the skin and soles of the feet; 2 nipples on one side of the chest; and reduced vertical facial height. An intraoral examination revealed anodontia; there were no teeth on the maxilla or the mandible and no radiographically identified tooth germ. Dry mouth due to a lack of sufficient saliva was another finding. Conclusion: In this case report, in the presence of anodontia, a removable total prosthesis, which is a non-invasive treatment option, was applied. Production of endosseous implants was postponed for a later time following the patient’s growth and development. How to cite this article: Gökçe D, Ayna E, Seyfioğlu Polat Z.
