Factors associated with sealant outcome in 2 pediatric dental clinics: a multivariate hierarchical analysis.
ABSTRACT This study's purpose was to determine whether one-time sealants placed by pediatric dental residents vs dental students have different outcomes. The effect of isolation technique, behavior, duration of follow-up, and caries history was also examined.
Records from 2 inner-city pediatric dental clinics were audited for 6- to 10-year-old patients with a permanent first molar sealant with at least 2 years of follow-up. A successful sealant was a one-time sealant that received no further treatment and was sealed or unsealed but not carious or restored at the final audit.
Charts from 203 children with 481 sealants were audited. Of these, 281 sealants were failures. Univariate analysis revealed longer follow-up and younger age were associated with sealant failure. Operator type, child behavior, and isolation technique were not associated with sealant failure. After adjusting for follow-up duration, increased age at treatment reduced the odds of sealant failure while a history of caries reduced the protective effect of increased age. After adjusting for these factors, practitioner type, behavior, and type of isolation were not associated with sealant outcome in multivariate analysis.
Age at sealant placement, history of caries prior to placement, and longer duration of follow-up are associated with sealant failure.

ABSTRACT: INTRODUCTION: Pit and fissure sealants are indicated to prevent caries in occlusal surfaces. OBJECTIVE: The aim of this study was to evaluate pit and fissure sealants applied by Dentistry undergraduate students of the Regional University of Blumenau (FURB), Santa Catarina. MATERIAL AND METHOD: The retrospective descriptive study was developed in three stages: the analysis of the records of the Department of Screening, being used as an inclusion criterion the existence of X-rays of the sealed teeth. In the second step we analyzed the radiographs of selected records and medical history of the child. The third step was performed by clinical and radiographic examinations, when conditions of pit and fissure sealants were verified. RESULT: We analyzed 800 medical records, and selected 131 (16.37%) for the second step, where it was observed that 321 pit and fissure sealants were applied. 119 (90.84%) children attended the control dental appointment, when confirmed the application of 160 (49.85%) resin, 126 (39.25%) glass ionomer cement and 35 (10.90%) flowable composite. We observed 296 (92.21%) sealants in permanent teeth. The clinical examination revealed that 114 (35.51%) of the sealants were completely lost at different periods of time. No caries lesion was observed in 294 (91.59%) teeth sealed. CONCLUSION: It was found that the pit and fissure sealants applied by students of the FURB School of Dentistry were effective in maintaining the majority of tooth surfaces free of caries, even when they were partially or totally lost.Revista de Odontologia da UNESP. 10/2012; 41(5):324-329.
