In the most severe form of the disease, recessive dystrophic EB (RDEB), the blister-inducing split occurs below the lamina densa. Extensive scarring of the oral mucosa results in limited mouth opening, making speech and mastication difficult. At the same time, oral mucosal blisters often lead to patients restricting their diets to soft, and generally cariogenic, foods, and battling with oral hygiene practices. This results in poor plaque control, a high caries burden and complex dental management. \u0000Aims and objectives: \u0000This paper presents a report on two siblings suffering from generalised RDEB affecting the oral cavity and their extensive dental treatment needs. \u0000Design/Methods: \u0000The siblings were referred to the University of Pretoria Oral Health Centre, complaining of painful teeth and oral mucosal discomfort. Their clinical features, dental condition and subsequent management are presented. \u0000Results: \u0000Restricted mouth opening, limited personal plaque control, and diets limited to soft, carbohydrate-rich foods because of oral mucosal discomfort, resulted in extensive dental decay that required multiple extractions. \u0000Conclusions: \u0000The dental and anaesthetic management of patients with RDEB is complex, and due to the friable tissues, requires the most atraumatic care possible. Ideally, patients with this condition need to have early dental intervention where preventive programmes can be implemented to reduce the need for later extensive and complicated dental interventions. Maintenance of the patient’s oral health is essential to ensure adequate nutrition, yet, reducing the consumption of soft cariogenic diets which increased their caries risk.","PeriodicalId":79721,"journal":{"name":"SADJ : journal of the South African Dental Association = tydskrif van die Suid-Afrikaanse Tandheelkundige Vereniging","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46366975","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}

Data collected included age, gender, aetiology of injury, site of injury, severity and extent of injury, fracture pattern and site, waiting period for treatment and month of injury. Chi-square test was used to evaluate the association between variables. The level of significant was set at p ≤ 0.05. \u0000Results: A total of 197 patients were seen in the two institutions with maxillofacial injuries for the years 2019 and 2020 with ages ranging from 1 to 81 years and a mean of 36.24. Most patients were males 167(85%). Many patients were seen in 2019 at 139(71%). There was no association between the fracture site and the aetiology. The mandible was significantly the most common site of injury and more conservative treatment was done as compared to other forms of treatment (p < 0.05). \u0000Conclusion: More Maxillofacial cases were seen in 2019 than in 2020 with more males as compared to females.

Many of these diseases are rare and the discipline less well known – making it essential to identify the obstacles this discipline faces. The purpose of this study was to describe the private and academic practice of Oral Medicine. A self-administered, internet-based, questionnaire was distributed to South African periodontists which questioned the clinician’s competency, diseases managed, special investigations performed, referral sources, proportional time and monetary distribution of the discipline, and perceived barriers to the practice. Twenty-six periodontists completed the questionnaire. In comparison to periodontology and implantology, periodontists generally feel less competent, spend less time on, and receive less money from Oral Medicine. Lack of awareness of the speciality (55.6% - 59.3%) was identified as the biggest constraint, with only 11.2% of referrals received from medical doctors. Immune-mediated diseases (29.3%) and benign neoplasms (26.5%) are managed the most, and surgical biopsies (80.2%) are used most regularly to diagnose oral mucosal disease. Oral Medicine is still a lesser-known clinical speciality. Despite the heavy burden of HIV-related oral disease and oral mucosal malignancies, this speciality remains underutilised.","PeriodicalId":79721,"journal":{"name":"SADJ : journal of the South African Dental Association = tydskrif van die Suid-Afrikaanse Tandheelkundige Vereniging","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44109922","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}

Although they are considered benign lesions, they are characteristically associated with pre-malignant or malignant lesions such as squamous cell carcinoma, actinic keratosis, keratoacanthoma, basal cell carcinoma and Kaposi sarcoma.

Zirconia has been tested for the marginal gap and internal fit; Enamic and Crios have not been tested for marginal gap and internal fit and no studies have tested the effect of different luting spaces. A standardised crown preparation on a typodont mandibular first molar tooth was scanned and imaged (CEREC CAD/CAM, Germany). The marginal gap was measured using a Reflex microscope in both two- and three-dimensions. The internal fit was calculated using the properties of the luting agent and the surface area of the preparation. The 3D measurements were significantly higher, but only on average 10µm higher. The marginal gaps of the crowns milled with a 200µm luting space were significantly smaller than for those milled with a 100µm luting space. The smallest mean gap was recorded by Enamic at 31.7µm followed by Crios at 32.5µm, and Zirconia at 33.1µm. All of these measurements are well within acceptable clinical limits. All crowns milled, regardless of the luting space used, provided excellent marginal and internal fit, well within clinically acceptable parameters. The 3D measurements are more clinically relevant than 2D measurements. The smallest marginal gaps were found in the crowns milled with a 200µm luting space.
