They were divided into two groups based on decayed, missing, and filled permanent and deciduous teeth (DMFT\/dmft) scores and counts of mutans streptococci (MS) prior to treatment. One was the low caries risk group (n \u200a=\u200a 26) and the other was the high caries risk group (n \u200a=\u200a 16). Paraffin-stimulated whole saliva was collected for examination of salivary flow rate, buffer capacity, and MS and lactobacilli (LB) levels before treatment, 2 and 4 months after appliance placement, and 2, 4, and 8 months after appliance removal.<\/jats:p>\n        <\/jats:sec>\n        <jats:sec>\n          <jats:title>Results:<\/jats:title>\n          <jats:p>The pretreatment salivary flow rates, buffer capacity, and MS levels remained statistically unchanged during and after active orthodontic treatment in both groups. The levels of LB in the high caries risk group were significantly elevated by appliance placement, but upon appliance removal started to fall significantly and came a little short of the pretreatment levels. In the low caries risk group, the pretreatment levels of LB remained statistically unchanged during and after treatment. There were no significant differences in salivary flow rate or buffer capacity, but there were significant differences in MS and LB scores between the two groups at every measurement time.<\/jats:p>\n        <\/jats:sec>\n        <jats:sec>\n          <jats:title>Conclusions:<\/jats:title>\n          <jats:p>In children undergoing orthodontic treatment with sectional brackets, LB levels are an important part in making caries risk assessment.<\/jats:p>\n        <\/jats:sec>","DOI":"10.2319\/072909-431.1","type":"journal-article","created":{"date-parts":[[2010,1,5]],"date-time":"2010-01-05T15:19:40Z","timestamp":1262704780000},"page":"509-514","source":"Crossref","is-referenced-by-count":25,"title":["Caries Risk Factors in Children under Treatment with Sectional Brackets"],"prefix":"10.2319","volume":"80","author":[{"given":"Sugako","family":"Sanpei","sequence":"first","affiliation":[{"name":"Lecturer, Pediatric Dentistry, Nippon Dental University Niigata Hospital, Niigata, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toshiya","family":"Endo","sequence":"additional","affiliation":[{"name":"Professor and Department Chair, Orthodontic Dentistry, Nippon Dental University Niigata Hospital, Niigata, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shohachi","family":"Shimooka","sequence":"additional","affiliation":[{"name":"Professor and Department Chair, Pediatric Dentistry, Nippon Dental University School of Life Dentistry at Niigata, Niigata, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1164","reference":[{"key":"i0003-3219-80-3-509-b01","series-title":"J Orofac Orthop","first-page":"353","article-title":"Enamel demineralization during fixed orthodontic treatment\u2014incidence and correlation to various oral-hygiene parameters.","volume":"68","author":"Lovrov, S.","year":"2007","unstructured":"Lovrov, S., K.Hertrich, and U.Hirschfelder.
