Pulp calcification in traumatized primary teeth: prevalence and associated factors.

AIM: To establish the prevalence of pulp calcifications in 946 patients at the Research and Clinical Center of Dental Trauma in Primary Teeth. STUDY DESIGN: The clinical and radiographic records of l675 traumatized primary teeth were evaluated. Statistical analysis was performed using chi-square and univariate logistic regression. RESULTS: 197 (20.8%) patients showed pulp calcification (PC). A total of 250 (14.9%) calcified teeth were observed In most teeth, PC appeared within the first 12 months following trauma. PC prevalence was higher in cases of repeated trauma (29.6%) than in single trauma (16.4%), p < 0.05, with a 2.14 chance of showing pulp calcification when a child suffered recurrent trauma. Most teeth showing calcified pulp, suffered trauma to the supportive tissue (67.4%), being statistically significant in relation to the trauma to dental tissue (p < 0.05). CONCLUSION: PC is a sequelae in cases of trauma to the primary dentition; teeth that suffered recurrent traumatic injuries show higher risk of presenting.

Oral manifestation associated with multiple pituitary hormone deficiency and ectopic neurohypophysis.

Multiple pituitary hormone deficiency (MPHD) is the diminished secretion of all the hormones produced in the anterior lobe of the pituitary gland. The oral manifestation of this condition includes delayed eruption and prolonged retention of primary teeth, delayed formation and eruption of permanent teeth, delay in development and growth of the jaws, tendency towards development of deep bite and enamel disturbances. This paper reports the case of an adolescent patient with MPHD. Clinical examination revealed partial ankylosis and prolonged retention ofprimary second molars, primary maxillary canines and deep bite. Dental treatment included extraction of all molars with prolonged retention preceded by the necessary medical care with clinical and radiographic follow-up afterwards. The patient was also referred to an orthodontist for orthodontic treatment. Patients' medical condition should always be investigated by clinicians when faced with cases of delayed tooth eruption and bone development.
