Root Surface Caries

We examined the skeletal remains of 1338 early Hawaiians (preserved in the Bishop Museum, Honolulu) to determine total caries and root surface caries prevalence. Specimens from seven islands were represented in the collection. Estimation of age at death was made by a combination of dental developmental staging for younger individuals and occlusal attrition and/or alveolar bone loss in adults. Museum records were also consulted for age estimation of adults which was primarily based on osteological criteria. The material was divided into six age groups. Predentate infants and edentulous adults were not included. A total of 19,425 teeth was examined. Caries lesions were observed in 462 individuals (34.5%) and 1895 teeth (9.8%). Coronal caries lesions in children and adolescents tended to be small and not particularly destructive of tooth structure. Root surface lesions in young adults were also small but increased progressively in size in the older groups, resulting in pulp exposure and coronal amputation. Although coronal caries was apparently not a significant dental health problem in children and young adults (compared with contemporary Hawaiians), root surface caries was an increasingly important source of tooth morbidity and tooth mortality in the older population groups. This age-related caries pattern was similar for all of the islands.

Relative glycogen synthetic abilities of resting cells of fresh clinical isolates of Actinomyces viscosus and Actinomyces naeslundii originating from dental plaque samples over root surface caries lesions and non-carious sites were studied under anaerobic conditions at a constant pH of 7.0, with U-(14C)-glucose used as the carbon source. Although the rates of glucose utilization and total acid formation were essentially the same, A. viscosus strains isolated from root surface caries lesions showed glycogen synthetic abilities approximately two to seven times higher than did A. viscosus strains originating from non-carious sites, and also two to four times higher than did A. naeslundii strains originating from both carious and non-carious sites.

The aim of this study was to measure the caries prevalence in the root surface in a group of Brazilian adults. The prevalence and their intraoral distribution of caries lesions of root surface were assessed in dental patients ranging in age from 35 to 44 and from 50 to 59 years of age of both sexes (n=360). A total of 98.9% had root surfaces with gingival recession and 78.1% had at least one root caries lesion. The prevalence of the disease was analyzed using the Root Caries Index (RCI). The average value was greater for women (18.6%) than for men (13.4%) (p<0.01) and similar in both age groups (p>0.01). The maxillary canines and first premolars and the mandibular molars presented the greatest RCI values. The RCI was greater in the proximal surface of the maxilla and buccal surface of the mandible. We conclude that caries of the root surface are present in the Brazilian population and deserve attention concerning their actual role in the epidemiology of principal oral diseases of the adult population.

Annual Application

Dental root caries is a common disease among elders. More efforts on preventing this disease are needed. Silver diammine fluoride (SDF) is known to prevent dental caries in primary teeth. However, clinical evidence of its efficacy in preventing root surface caries is limited. This clinical trial aimed to compare the effectiveness of SDF in preventing root caries among elders in a water fluoridated area. A total of 323 elders who had at least 5 teeth with exposed root surfaces and who had self-care ability were randomly allocated into 3 intervention groups: group 1 (placebo control), annual application of tonic water; group 2, annual application of SDF solution; group 3, annual application of SDF solution, immediately followed by potassium iodide (KI) solution. Oral hygiene instructions and fluoride toothpaste were provided to all subjects. Status of dental root surface was assessed every 6 mo by the same independent examiner. After 30 mo, 257 (79.6%) elders were reviewed. The mean numbers of root surface with new caries experience in the control, SDF, and SDF/KI groups were 1.1, 0.4, and 0.5, respectively (analysis of variance, P < 0.001). Scheffe’s multiple comparison showed that elders who received placebo developed more new root caries lesions ( P < 0.05), while the difference between the SDF and SDF/KI groups was not statistically significant ( P > 0.05). Moreover, elders who had higher visible plaque index scores at 30-mo examination (analysis of covariance, P < 0.001) and those who had higher baseline DMFT scores (analysis of covariance, P = 0.005) developed more new root caries. It is concluded that annual application of SDF or SDF/KI solution is effective in preventing root caries among community-dwelling elders in a fluoridated area ( ClinicalTrials.gov NCT02360124). Knowledge Transfer Statement: Annual topical application of silver diammine fluoride or silver diammine fluoride / potassium iodide solution is effective in preventing dental root surface caries among community-dwelling elders in a fluoridated area.

Successful use of atraumatic restorative treatment (ART) in children has been reported, but little information is available regarding its use in older adults. The hypothesis of this study was that survival rates of root restorations placed by both ART and the conventional technique were similar. Root-surface caries lesions in 103 institutionalized elders in Hong Kong were treated randomly by either: (1) the conventional approach—caries removed by dental burs, and the cavity filled with light-cured resin-modified glass ionomer; or (2) the ART approach—caries removed by hand instruments, and the cavity filled with chemically cured high-strength glass ionomer. In total, 84 conventional and 78 ART restorations were placed. After 12 months, 63 conventional and 59 ART restorations were reviewed, and the respective 12-month survival rates were 91.7% and 87.0% (p > 0.05). It is concluded that the survival rates of both types of root restorations were high and similar.

Root Surface Caries

After some problems resulting from the lack of standardized methods in the conduct of root caries studies and the lack of standardized reports of findings are reviewed, the prevalence and incidence of root surface caries in North America are reviewed through a combination of epidemiologic studies and large clinical trials. As part of this review, the available evidence on the relationship between root caries and missing teeth is presented. These data lead to the conclusion that the prevalence and, to some extent, the incidence of root caries are underestimated in adults with missing teeth. This review resulted in a number of observations regarding the status of root caries as an oral health problem. First, there is little evidence that would allow conclusions regarding the secular increase or decrease in the prevalence or incidence of root caries to be drawn. Other observations gleaned include the remarkably similar prevalence and incidence rates obtained from the studies reviewed, positive associations between root caries and age, negative associations between the prevalence and incidence of root caries and consumption of water containing fluoride, indications that root caries is a problem in adults with incidence rates that approach caries rates in children, and associations between the prevalence and incidence of root caries and a wide variety of oral, behavioral, and medical conditions. The final observation is the need for the acceptance of conventions for the definition of root caries as well as the reporting of findings in order for more firm conclusions to be drawn from future studies.

Demineralized Dentin

A dentin primer containing the antibacterial monomer 12-methacryloyloxydodecylpyridinium bromide (MDPB) has been shown to penetrate and kill the bacteria in artificially demineralized dentin. We hypothesized that an experimental adhesive system, which incorporates the MDPB-containing primer, would be effective in inhibiting the progression of root caries in vitro. Artificial caries lesions were prepared by either an acid-gel or a Streptococcus mutans culture technique on the roots of extracted human teeth. The progression of these lesions after the application of the experimental or proprietary adhesive system was examined. Further demineralization was completely prevented by the experimental adhesive system, while lesions managed with the proprietary materials showed limited ability to inhibit further demineralization. We conclude that the experimental adhesive system can inhibit the progression of root-surface caries in vitro, through a combination of its antimicrobial activity and sealing of the demineralized dentin.

Sucralose is an intensely sweet, chlorinated carbohydrate structurally similar to sucrose; thus, its cariogenic potential is of great interest. Four groups of 12 Sprague-Dawley rats were infected with Streptococcus mutans (sobrinus), caged in a Konig-Höfer programmed feeding machine, and fed diet 2000 or modified diet to contain sucralose at various concentrations instead of sucrose. Rats fed sucralose diet developed significantly fewer lesions than did the rats fed regular diet 2000. Animals fed diet 2000 also harbored more S. mutans (sobrinus) than did the other groups of animals. In a concurrent study, desalivated rats were inoculated with S. mutans (sobrinus) and Actinomyces viscosus. They were fed (ad libitum) either diet 2000 (contains 56% sucrose) or diet 2000 minus sucrose plus 93 mg% sucralose. The severity of caries lesions in the sucralose-fed rats after 35 days was significantly less than those in the sucrose-fed rats. The amount of root exposure was the same in both groups. However, root-surface caries did not develop in the sucralose-fed rats. These results show that sucralose is non-cariogenic in rats.
