    Mucosal sensitivity to chlorhexidine mouthwash is a rare occurrence and very few cases have been reported in the literature. The authors report 2 cases of oral sensitivity to chlorhexidine and discuss the side-effects, possible causes of sensitivity and the management of the cases.

    This is a retrospective study of 80 patients with major central and lateral middle third fractures of facial skeleton treated at University Hospital from 1981 to 1985. The most common was the fractures of zygomatic complex. The peak incidence was in the 20-29 year age group and males were involved more than females (ratio 9: 1). Road traffic accidents were to be blamed for most of the fractures which was 82.25%.

    The sugar content of twenty-four liquid medicines commonly prescribed for infants and young children were measured and the type of sugars present were also identified in four randomly selected samples. All the liquid medicines tested contained sugar, in the range of 29.4% to 61.2%. Sucrose appeared to be the most commonly used sugar. Whilst it is agreed that sucrose makes the medicine more acceptable to children, its continual use by the pharmaceutical industry should be discontinued due to its harmful effect on the dental health of children, particularly those taking these syrup-based medicines on prolonged basis. Sugar-free alternatives such as sorbitol or saccharin should be used instead.

    A sporadic case of Crouzon Syndrome without mental retardation is described. The patient, an 11 year old boy with grossly carious teeth and in severe pain was referred for dental treatment. A review of literature on Crouzon Syndrome is presented.

    Delayed replantation of an avulsed tooth with an open apex resulted in failure of revascularization, necrosis of the pulp and extensive external root resorption. Removal of the necrotic pulp and repeated intra-canal dressings of calcium hydroxide over a three year period arrested the inflammatory resorptive process. The process was replaced by replacement resorption leading to ankylosis and infra-occlusion of the affected tooth. As the tooth was asymptomatic, it was retained in the arch to act as a space maintainer. To improve aesthetics, the crown was recontoured using a light-cured resin.

    A case of an incomplete tooth fracture followed by a complete fracture was presented. The difficulty of diagnosing this condition was discussed as well as the possible histological explanation of the symptoms experienced by the patient. It once again points out to practising dentists, that whilst deep pockets can give rise to severe periodontal pain, intense and excruciating pain should be investigated with the cracked tooth in mind.

    Early-onset periodontitis in children, teenagers and young adults is quite rare. This form of periodontitis progresses very rapidly and cause massive destruction to the periodontium. Various names have been given to this condition since it was first recognised in the 1920s. Through time the nomenclature changed from one to the other. Currently 3 forms of early-onset periodontitis are recognised--i.e. prepubertal periodontitis (PPP), localised juvenile periodontitis (LJP) and rapidly progressive periodontitis (RPP). The clinical features of juvenile periodontitis as it was first described together with that of the present 3 clinical entities mentioned above are presented. Concepts on the aetiology of the disease have also changed through time, and include degenerative process, bacterial infection, defects in the host defense system and heredity. Current thought is that there is an interplay of most of these factors in pathogenesis of the disease. Treatment modalities changed too. At the moment, comprehensive periodontal therapy with meticulous oral hygiene measures seem to be the treatment of choice. Concurrently, systemic tetracycline administration might have some added benefits.

    Although the patterns of dental disease is gradually changing, caries and periodontal disease still account for the most important reason for extractions in most countries. However their relative contributions towards overall tooth mortality figures varies. The aim of this study is to investigate the types of teeth usually associated with extractions due to caries or periodontal disease and its relation to the age at which the tooth was lost. The highest proportion of extractions due to caries occurred between 21 to 30 years of age while that for periodontal disease occurred between 41 to 50 years. For caries, the greatest proportion of extractions involved the posterior teeth. The most frequently extracted teeth due to caries are the molars, in particular the first permanent molar. However, for periodontal disease a slightly greater proportion of anterior teeth were lost than the posteriors. This trend is more marked in the lower jaw than the upper. Overall, extractions related to caries tend to increase posteriorly, while that for periodontal disease tend to increase anteriorly.

    Many studies have been reported on radiographic lesion sizes of periapical lesions. However no studies have been reported on prevalences of subjective radiographic features in these lesions except for the early assumption that a periapical cyst usually exhibit a radiopaque cortex. This study is conducted to evaluate the prevalences of several subjective radiographic features of periapical cysts and granulomas in the hope to identify features that maybe suggestive of either diagnosis. The results showed that a regular (circular or semi-circular) radiographic outline is likely to be a periapical cyst while an irregular radiographic outline is not indicative of either a cyst or a granuloma. The association between the regular/irregular radiographic outline and the type of periapical lesion was found to be statistically significant (p less than 0.001). The associations of two other radiographic features and the type of periapical lesion were found to be just statistically significant (p less than 0.01). These features are the symmetry/asymmetry of the radiolucency in relation to the apex and the funnel-shaped/angular-shaped extension of the radiolucency. The widely accepted criteria that the possession of a radiopaque cortex surrounding the radiolucency can discriminate between a periapical cyst and granuloma cannot be statistically supported in this study.
