The Use of Hall's Technique Preformed Metal Crown (HTPMC) by Pediatric Dentists in Malaysia.

INTRODUCTION: Hall's technique preformed metal crown (HTPMC) has been used widely by pediatric dentists in developed countries as a new approach for managing decayed primary molars without local anesthesia, caries removal, and tooth preparation. Currently, inadequate information is available regarding the implementation of this technique (HTPMC) in Malaysia. This study is aimed at evaluating the implementation of HTPMC by Malaysia's pediatric dentists and identify the co-occurrence frequencies of the HTPMC implementation with the respondents' demographic profile. MATERIALS AND METHODS: A cross-sectional questionnaire-based research was conducted among 65 pediatric dentists in Malaysia. Online questionnaires were distributed to the pediatric dentists employed at public hospitals (MOH) and universities in Malaysia. RESULT: It was found that over half of the respondents (65.6%) employed HTPMC. The analysis of the co-occurrence network frequency revealed that a high frequency of female pediatric dentists who were within the age group of 31-40 years old had fulfilled their postgraduation overseas and was employed in the university mainly applied HTPMC. CONCLUSION: The application of HTPMC among respondent pediatric dentists in Malaysia was high. However, most respondents considered HTPMC a treatment option only to manage carious primary molar rather than a treatment of choice.

Oral necrotizing microvasculitis in a patient affected by Kawasaki disease

Kawasaki disease (KD) was first described in 1967 by Kawasaki, who defined it as “mucocutaneous lymph node syndrome”.KD is an acute systemic vasculitis, which mainly involves medium calibre arteries; its origin is unknown, and it is observedin children under the age of 5, especially in their third year.The principal presentations of KD include fever, bilateral nonexudative conjunctivitis, erythema of the lips and oral mucosa, changes in the extremities, rash, and cervical lymphadenopathy.Within KD, oral mucositis – represented by diffuse mucous membrane erythema, lip and tongue reddening and lingual papillae hypertrophy with subsequent development of strawberry tongue – can occur both in the acute stage of the disease (0-9 days), and in the convalescence stage (>25 days) as a consequence of the pharmacological treatment. KD vascular lesions are defined as systemic vasculitis instead of systemic arteritis. This study analyzed the anatomical-pathological substrata of oral mucositis in a baby affected by Kawasaki disease and suddenly deceased for cardiac tamponade causedby coronary aneurysm rupture (sudden cardiac death of a mechanical type)

Diagnostic evaluation of serial sections of labial salivary gland biopsies in Sjögren’s syndrome

No disponible

Objectives: Sjögren’s syndrome is a chronic inflammatory disease. The detection of chronic inflammatory infiltrates containing >50 lymphocytes (lymphocytic focus) per 4 mm2 tissue in minor salivary gland biopsies is a diagnostic parameter of the disease. The aim of the study was to examine if an increase in the tissue area of a single minor labial salivary gland biopsy through serial histological sections in patients affected by primary Sjögren’s syndrome could facilitate thedetection of the diagnostic focus score (grades >1 or >2).Methods: We observed 24 labial salivary gland biopsies from patients affected by primary Sjögren’s syndrome, diagnosed according to the clinical-laboratory criteria proposed by the American-European Consensus Group.The analysis was carried out on sections (n= 72) obtained at three different levels at 200 micrometers from one another.The serial sections regarding the 3 levels were reviewed by the same oral pathologist, who detected both the total number of foci, and their surface, calculating a cumulative focus score.Results: No significant correlation was found between the number of lobules per histological section and the focus score (Pearson correlation 0.363, p= 0.01). No significant variation in focus score distribution was identified in the three serial histologicallevels at 200 micrometers from one another. From the comparison between the number of lobules observed and the focus score grade, no direct proportionality between the amount of parenchyma analyzed and the focus score was found.Conclusions: The focus score remained unchanged in the serial sections at different depths (AU)
