Prevalence and Analysis of Factors Related to Occurrence of Pulp Stone in Adult Restorative Patients

Background: Pulp stone; though of an unclear aetiology; is clinically common. It potentially poses procedural difficulty to the endodontist and may also be a marker of an underlying systemic condition. Objectives: The study investigated pulp stone occurrence in adult restorative patients. It also highlighted the relationship between pulp stone and pristine posterior teeth; chronic periodontitis and posterior teeth with abrasion; as well as the effect of age and gender on pulp stone occurrence. Method: Three hundred subjects; aged 18-60 years participated in the cross sectional study. Pristine teeth; teeth with chronic periodontitis and those with abrasion were recruited. Result: Pulp stone was seen more often in the 41-50 years age band; in molars and in teeth with chronic periodontitis but less often in teeth with abrasion. In addition; coronal and free form of pulp stone were more popular. Conclusion: It is recommended that researchers should pay special care in case selections; and during biomechanical coronal instrumentation

Perceived Visual Deterioration among a Selected Group of Dental Surgeons in Nigeria

To assess the perceived visual deterioration and the determinants among selected dental surgeons in Nigeria. A cross-sectional survey of Resident doctors attending the Revision course of Faculty of Dental Surgery of the National Postgraduate Medical College of Nigeria in Lagos University Teaching Hospital; Lagos; Nigeria was conducted in October; 2008. The 21-item self-administered questionnaire was used to obtain demographic information; medicated eyeglass use; self-rating of vision on start of dental practice; self-rating of vision presently; self-rating of illumination in dental operatory; procedure that can be done without adequate illumination and procedures that need light enhancers. Majority of the respondents were male; in the 31-35 year age group; had less than 10 years post-graduation experience and are specializing in oral and maxillofacial surgery. Perceived visual deterioration was reported by 22 (36.1) of the respondents. Respondents who are 46-50 years; male; with _ 10 years of experience; using medicated eyeglass and specializing in Restorative dentistry reported higher perceived visual deterioration. The prevalence of use of medicated eyeglass was 22 (36.1). The illumination of dental operatory was good by 35 (57.4) of the respondents using a self-rating scale.The predominant procedures performed under limited illumination were oral surgical 16 (26.2) and orthodontic 16 (26.2). Light enhancers were advocated by respondents mostly during restorative procedures. Perceived visual deterioration in this study was high. This justifies the need for assessment of vision at employment and longitudinal assessment of vision annually inorder to objectively ascertain the level of visual deterioration
