Type of Article: Retrospective
Main Purpose: To investigate the relationship between the dmft/DMFT score and the success of a Sealant
Overview of method of research: Children aged 5.5 to 15 years old, were examined twice by the school-based sealant program between 1997 and 2002, and had least one sealant placed on a permanent first molar were included in the study. The dentist diagnosed the need for a sealant, a hygienist (94%) or a senior dental student placed the sealants and all sealants were checked that day by the supervising dentist. Follow-up visits ranged from 6 months to 5 years. Teeth were then classified as a success if the tooth that was sealed initially now was still completely or partially sealed or was caries free, or a failure if the tooth appeared carious or restored on the second examination.
Findings: For the primary dentition and permanent dentition, for teeth that were examined within the first year of placement there was no difference between a dmft/DMFT of 0 or a dmft/DMFT>0. After a follow-up period of more than 1 year children with a dmft/DMFT of 0 were half as likely to have a sealant failure than children with a dmft/DMFT score of >0.
Key points/Summary: Children with a high caries risk are more likely to get caries on teeth that were sealed after the first year of placement and should be monitored regularly. Assessment of article: Interesting to note that if the sealant was partially present or no longer there it was still considered a success.

Main Purpose: Discuss decision making for caries management in children
Overview of method of research: Review
Findings: A few factors should be taken into consideration when treating caries: 1. Location and extent of the lesions, 2. patient’s age, 3. Assessment and reassessment of disease activity, 4. prior therapy outcomes, 5. natural history of caries progression, and 6. preferences and expectations of guardians and practitioners. Studies show that the earlier a child becomes colonized with s. mutans, the greater their caries risk. We can assess this with microbiological tests, but when carious lesions are already present in young children (especially on upper incisors and molar proximal surfaces) it goes without saying that these patients are high caries risk. When determining whether to take preventative measures or perform operative dentistry, one factor to consider is that buccal-lingual smooth surface lesions respond better to these regimens than cavitated fissure/proximal lesions. A few studies demonstrated the average growth rate of proximal enamel-only lesions, showing that in primary teeth it takes about a year for them to spread to the dentin. Permanent proximal lesions took from one to three years. Many different modalities are available for the diagnosis of dental caries, but although they may have high specificity (ability to rule out caries), none have a high sensitivity (ability to confirm the presence of caries. Interestingly, a study showed that bitewing radiographs showed better sensitivity than clinical exam in pit/fissure caries extending to the dentin. This paper mentions the fact that in in-tact sealant can seal-in and “deactivate” caries… as long as the integrity of the sealant maintains. This paper mentions risk factors for caries which include low birth weight, age of colonization, s.mutans levels, presence of visible plaque, and sociodemogaphic factors. Toothbrushing and avoiding sweets make sense on a microbiological level, but have yet to be proven in in vivo longitudinal studies. This paper recommends fluoride supplementation only in non-fluoridated communities in moderate-to-high risk patients whose parents understand risks and benefits. We should focus instead on the topical effects of fluoride. Toothbrushing is lauded mainly for its ability to deliver fluoride – moreso than for it’s plaque-reduction, interestingly enough.
Key points/Summary : This paper is best summed up by it’s recommendation that “dental care should be based on preventive services and supplemented by restorative therapy only when indicated.”
Assessment of article: Good position paper.
