ABSTRACT
Deciduous dentition has significant importance to child’s aesthetics, phonation,
mastication and welfare. In addition, it maintains a gap that allows a favorable
eruption of the successor permanent tooth. Thus, dental pulp treatment becomes
essential to preserve deciduous teeth up to their exfoliation period. This study aimed
to evaluate clinical and radiographic success of deciduous teeth endodontically
treated with an antibiotic paste including chloramphenicol, tetracycline and zinc oxide
(CTZ), at Pediatric Dentistry Clinics, Federal University of Paraiba, completed in the
period between 2008 and 2010. Thirty-six teeth (25 low molars, 08 upper molars and
03 incisors) endodontically treated with such an antibiotic paste were clinically and
radiographically analyzed. Clinical examination has revealed changes in the
normality of the deciduous teeth and in their permanent successors. The main
variations detected were presence of pain, abscess, mobility and color changes in
the deciduous teeth crowns. In the permanent successors, changes affecting crown
color, size and shapehave also been observed. A periapical radiograph of each
dental element was obtained and then compared to the diagnosis radiograph on
viewing boxes, assessing suggestive images of bone resorption, external root
resorption and internal root resorption. Data were typed (feeding a database), and
processed quantitatively. Then, all records underwent descriptive analysis by using
SPSS 13.0.From the thirty-six teeth analyzed only five elements were found to
present clinical changes classified as unsuccessful, what represents a success rate
of 86% for endodontic treatments using CTZ paste. Pulp therapy using such paste
has showed excellent clinical and radiographic outcomes in teeth with unfavorable
prognosis, allowing therefore tooth maintenance up to the exfoliation period.
Nevertheless, its use in pulpotomies in primary teeth is promising, even though
further clinical trials are required.
