Dose-response evaluation of a novel essential oil against Mutans streptococci in vivo

Research has demonstrated the need for identifying a novel antimicrobial agent for topical use in the pediatric dental population. The essential oil of Lippia sidoides Cham. (LSO) has been described as having favorable biological properties, and a broad in vitro and in vivo antimicrobial spectrum against bacteria and yeast infections. Our aim was to determine a dose and formulation of LSO, acceptable for clinical testing in a pediatric population with dental caries. Thirty-seven 6-12-year old children were selected to participate in this study, and randomly allocated to receive different concentrations of either a gel (0.8%, 1%, 1.2% and 1.4%) or a mouth rinse (0.6%, 0.8%, 1% and 1.2%) formulation. The highest percentage MS reduction was observed with 0.8% mouth rinse and 1.4% gel. The efficacy of these concentrations was compared with a Thy-Car mixture formulated as a mouth rinse and gel treatments in 11 children. Saliva was collected after a single application of the antimicrobial treatment to establish effectiveness against MS. Both rinse (p < 0.001) and gel (p = 0.02) formulations produced significant MS reduction. Mouth rinse concentrations above 0.8% were associated with a transient intra-oral burning sensation. In conclusion, mouth rinse and gel LSO formulations demonstrated effectiveness against MS and good acceptance among children. We suggest future randomized clinical trials to test its effectiveness against early childhood caries.

Log-linear analysis of dental caries occurrence in four skeletal series.

Four skeletal series (Corinth, Greece; Gran Quivira, New Mexico; Semna South, Sudanese Nubia, and a large group from scattered sites in England) were coded for sex, jaw, tooth group, dental attrition, dental caries, site and time period. Through thec concepts of a basal level of caries and a cariosity gradient, a single model was found which best described the occurrence of this disease in these samples. All factors were found to contribute significantly to the model. Within the possible subsamples the general characteristics are that the profiles of males, of the mandibulae and of those with light attrition are more likely to have lower overall dental caries levels and to be relatively more carious in the back of the mouth than the front when compared to the pooled sample of all teeth and caries. The opposite is also found to be generally true; the teeth of females, maxillae and heavy attrition are associated with more caries, especially toward the front of the mouth. These results imply that samples appearing otherwise homogeneous display much variation. They also reveal distinct regularities in the reactions of diverse human groups to dental caries.     

不同去龋技术在乳牙龋病治疗中的应用疗效分析

目的:比较传统机械切割法、非创伤性充填法(atraumatic restorative treatment,ART)和Carisolv化学法在临床乳牙龋病治疗中的应用效果差异。方法:选取2011年1月-2012年6月来我科就诊的5-8岁儿牙患者96名,患牙180颗,随机分为3个不同的治疗组:传统机械去龋组、ART组和Carisolv化学去龋组进行相应牙体充填治疗,通过去龋效果、去龋时间、术中疼痛发生率和术后长期疗效等方面比较不同去龋技术之间的差异。结果:常规机械去龋组和Carisolv组的去龋效果明显优于ART组(P0.05),二者之间无明显差异(P0.05);3种去龋方法的去龋操作时间无明显差异(P0.05);Carisolv组和ART组去龋治疗中患儿术中疼痛发生例数明显低于常规机械去龋组(P0.05),二者之间无明显差异(P0.05);治疗1年后的复诊发现,常规机械去龋组和Carisolv组中患牙继发龋发生率明显低于ART组(P0.05),二者之间无明显差异(P0.05);三种方法治疗后患牙充填物折断/脱落发生率无明显差异(P0.05)。结论:Carisolv化学去龋法能有效减轻术中疼痛和术后复发率,值得在临床乳牙治疗中推广应用;ART的去龋效果和远期疗效可能限制其广泛应用。

Investigating prevalence of dental anomalies in Eastern Province of Saudi Arabia through digital orthopantomogram

ObjectiveThe aim of this study was to investigate the prevalence of dental anomalies in the Eastern Province of Saudi Arabia using the digital Orthopantomography (OPG).MethodsA retrospective radiographic study was performed in which digital OPGs of 1189 subjects, ages ranging between 7 and 65 years were reviewed, and 1104 fulfilled inclusion criteria. Statistical analysis was performed. The OPGs were reviewed for congenitally missing teeth, impactions, ectopic eruption, supernumerary teeth, odontomas, dilacerations, taurodontism, dens in dente, gemination and fusion.ResultsOPGs of 1104 patients with mean age 35.32 ± 16.63 were included. The total prevalence of developmental anomalies in this study was 36.3% (401/1104). Male and female subjects with anomalies were 133 (33.2%) and 268 (66.8%) respectively. The prevalence of dilacerated teeth 300 (30.2%), congenitally missing teeth was 246 (24.7%), supernumerary teeth 18 (1.8%), talon cusp and taurodontism were seen in one patient each 1 (0.1%). Of these, a total of 15 (1.5%) anomalies were noted in pediatric patients.ConclusionsDilaceration was the most prevalent anomaly (30.2%) in the studied sample followed by congenitally missing teeth (23.4%). Talon cusp, concrescence/fusion, and taurodontism were the least prevalent anomalies.     

Secretor status and dental caries in Iceland

Abstract The proportion of non-secretors of ABH blood-group substances among Icelanders is one of the highest recorded for European countries. Dental caries prevalence is also very high. In this study of dental caries in young adults mean number of decayed, missing and filled teeth for secretors were 17.4 and for non-secretors 19.9 ( P < 0.05). A majority of patients seeking free dental treatment in the Dental School were non-secretors (62.7%) significantly more than the proportion of non-secretors in the general population (36%; P < 0.01). It is postulated that blood group substances may interfere with the adherence of Streptococcus mutants to teeth.     

Predictors of caries in old age

This study measured the incidence of dental caries for one year and identified factors associated with the risk of caries in a sample of 156 elderly subjects. The subjects were examined at baseline and after one year to record the number of missing, filled and decayed teeth, to measure oral hygiene and flow of saliva, and to estimate the numbers of Streptococcus mutans and Lactobacilli cultured from samples of saliva. All subjects were interviewed on both occasions for information on their use of medications and dental services and on their ingestion of sugar. At baseline the elders had a mean of 19 natural teeth with 5 decayed surfaces (DS), 38 filled surfaces and a mean Plaque Index (PI) of 1. The independent group, on average, had more teeth and fillings but a lower PI and less caries. At the end of the year more than two-thirds (71%) of the 98 institutionalised subjects and over half (59%) of the 58 independent subjects had at least one new decayed/filled surface (DFS). The mean net DFS increment per subject was 4.6 and 2.0 respectively. Regression analyses on multivariate models identified caries at baseline, residence in long term care facilities, high numbers of Lactobacilli, poor oral hygiene and frequent sugar consumption as the variables contributing most significantly to the risk of caries in old age.
