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

Incidence des troubles neuro-psychopathologiques sur l'etat bucco-dentaire. Enquete menee au centre neuro-psycho-pathologique CNPP) de l'universite de Kinshasa

Ce texte presente une etude menee au centre neuro-psychopathologique de Kinshasa au Zaire et concernant 98 malades des 2 sexes hospitalises qui revele que la grande majorite de ces sujets ont ont une hygiene buccale defectueuse. Outre les tartres; la carie dentaire et la gingivite qui constituent les pathologies orales les plus courantes; l'etude revele surtout une usure pathologique et inquietante des couronnes dentaires chez tous les malades : cette ablasion est imputable au bruxisme. Les auteurs estiment qu'il incombe aux psychiatres et neurologistes d'orienter periodiquement des malades mentaux vers les consultations odonto-stomatologiques
