Leiomyomas are benign neoplasms of smooth muscle origin. They represent rare entities in the oral cavity. A case arising from the incisive papilla region of a 3-month-old infant is described and the histogenesis as well as the biologic potential of this tumor are discussed.
The objective of the study was to attempt to verify the cause of self-reported oro-facial pain among 12-yearold children, objectively via a clinical examination. This is a descriptive, cross-sectional survey using a combination of self-reported questionnaire, face-to-face interview and clinical oral examination. The children were first asked to answer a self-filled questionnaire about their oro-facial pain experience in the past 4- weeks. In order to verify its cause, a clinical examination and an interview followed. Normative oral health status data was also collected. The sample was 1492 Malay schoolchildren with diverse socioeconomic background from the states of Johore, Kelantan and Sabah. The sample size for each state was calculated to give a sampling error of not more than 5 %. In each state, quota sampling was done to achieve a balanced distribution between gender and location. The data collected were normative status for caries, periodontal disease and traumatized teeth. Orofacial pain experience represented the subjective status for oral well-being. The cause of pain was confirmed through a clinical examination. The normative oral health status data implies a very low untreated disease and good oral health among the schoolchildren. However the subjective health status, as reflected by the prevalence of pain suggested that oro-facial pain and suffering was high (27.3%) with about 49% "of moderate and severe" intensity. The two main causes were caries and mouth ulcers. However in about onequarter of pain cases, diagnosis cannot be confirmed in the field survey setting. More than one-half of those with pain experienced disturbed sleep and study. It was concluded that overall oral health status and well-being can be better described if normative data is complemented with subjective data such as pain prevalence. The study shows that the majority (more than 75 %) of cases of subjective pain can be objectively verified in a field epidemiology survey setting. The reliability of the subjective data can be improved by a clinical examination as compared to unverified self-report. The study also confirms that the major source of oro-facial pain among the 12 year-olds were caries and mouth ulcers.
Most prosthetic joint infections originate from wound contamination or haematogenous seeding from distant sites of infection. Bacteraemia may follow dental treatment but there is little evidence of it related to prosthetic joint infection. Nevertheless, controversy continues with regards to the effect of dental treatment in patients with prosthetic joints. This article reviews current English literature regarding the use of antibiotic prophylaxis in the dental management of patients with prosthetic joints. Routine antibiotic prophylaxis is not recommended for every patient with prosthetic joints when receiving dental treatments. However, antibiotic prophylaxis may be prescribed for high-risk groups with predisposing factors to infection when undergoing dental treatment with high risk of bacteraemia.
This study evaluated the effectiveness of demineralized freeze-dried bone xenograft in reducing post-surgical pocket depth in moderate to advanced adult periodontitis in patients. Nine patients with a total of eighteen intrabony defects were selected for this study. The bony defects were matched for tooth type, location and pocket depth. Following an initial non-surgical treatment, only pockets of 5 to 7 mm deep were indicated for surgery. Periodontal pockets were measured pre-operatively and at 3, 6 and 9 months post-surgically. The study protocol included a split mouth design, where surgical treatment was carried out at both test and control sites. The test sites were assigned demineralized freeze-dried bone xenograft and the control sites were subjected to debridement alone without the use of demineralized freeze-dried bone xenograft. The results from this study showed a statistically significant difference in the mean pocket depth at 6 and 9 months post-operatively for both test and control groups, but there was no statistically significant difference at 3 months. In conclusion, demineralized freeze-dried bone xenograft was ineffective in reducing periodontal pocket depth in patients with moderate to severe periodontitis, as compared to surgical debridement alone.
Twenty-one patients who underwent ablative surgery for head and neck cancer at Bristol Dental Hospital and School, England between the years 1996 and 2002 were enrolled in the study. A self-completed questionnaire based on Head and Neck Specific measures was addressed to the patients. The overall post-operative quality of life among these patients is acceptable. About half of the patients complained of moderate to severe difficulty in opening mouth wide (55%) and dry mouth (45%) and about one-third had major problems in swallowing solid food (36%), sleep disturbance (32%), trouble eating and enjoying meals (32%) and speech problems (32%). The study shows a tendency for the quality of life to improve steadily with increasing post-operative interval. It is hoped that the results will provide an insight into the patients' functional and psychological recovery, which will in turn help to facilitate the planning of appropriate strategies to improve their quality of life.
This study is conducted to compare two resin luting cements (Rely XTMARC,3M and Compolute™ESPE) on their microleakage with one composite inlay system (Filtek™ Z250 Universal Restorative Materials, 3M). Thirty conventional inlays, Class II MOIDO cavity with gingival margin I mm above the cementoenamel junction, were prepared in premolar teeth. The composite inlays were fabricated directly on the prepared teeth using layering technique. Fifteen of the inlays were cemented with RelyTMX ARC and fifteen with Compolute™ (ESPE). The specimens were kept at 370 C for 10 days before thermocycling and immersed in methylene blue 2% solution for 24 hours. The teeth were sectioned mesio-distally. The site and degree of leakage of each section was scored using a visual scoring system under a stereomicroscope at a magnification of 1.5X. Results showed that there was no significant difference in'leakage extent (p>O.05), between Rely X™ARC and Compolute™. For both materials, leakage occurred most commonly within the enamel surface and between the cement-tooth interfaces. None of the leakage occurred between inlay - cement interface. There is no significant difference in the extent of leakage between Rely XTMARC compared to Compolute™.
The controversy on malignant transformation of oral lichen planus has always intrigued researchers. We present a case of lichenoid lesion and squamous cell carcinoma of the tongue, occurring in a middle aged Indian lady. The diagnosis and timing of these lesions is discussed.
Simulated canals in clear resin blocks have been widely used in pre-clinical endodontic teaching. The artificial canal provides direct visualisation of procedures in root canal treatment. Stanuardised simulated root canals have been produced in the Faculty of Dentistry, University of Malaya for dental education and research. The canals are easy and inexpensive to construct. An outline of the method of construction of resin simulated canals is presented in this paper.
The ultrastructure of the odontoblast reflects the certain phases that the cell undergoes in their lifecycle. Ultrastructure studies of the odontoblasts have often been carried out using young teeth. In this study, teeth from an older individual have been used to study the odontoblasts from the crown and root area. The odontoblasts from the crown area retain their columnar shape while odontoblasts from the root area appeared to be flattened. The organelles present in the odontoblasts either from the crown or root area was observed to be reduced.
Craniofacial superimposition methods are employed for the identification of unknown skulls or living persons. There are many such methods and of particular interest is that technique developed by Furue which is inexpensive to set-up. A study was undertaken to ascertain the validity of this technique and to correlate our findings with other researchers.
The role of smoking as a contributory factor in the progression of the periodontal disease process has long been suspected and recently a large number of studies have been published in the dental literature regarding this possible role. Much of the literature has also indicated that smokers affected with periodontitis respond less favorably to periodontal treatment be it non-surgical, surgical and regenerative. This paper will review the current literature regarding the effects of smoking on various aspects of the periodontal disease process and present an explanation for the possible association between smoking and the progression of periodontitis.
