Abstract

AIM

To evaluate the dental and salivary density of mutans streptococci among Iasi schoolchildren.

MATERIAL AND METHODS

This study cross-sectional included 533 schoolchildren aged 7-12 years. The density of mutans streptococci on dental surface (mesial and occlusal surfaces of teeth 1.6 and 3.6) and in saliva was assessed using Dentocult SM Strip mutans kits (Orion Diagnostica Oy) according to manufacturer's instructions. Subjects were given one of the following scores: 0 = < 10(4) CFU/ml; 1 = < 10(5) CFU/ml; 2 = 10(5)-10(6) CFU/ml; 3 = > 10(6) CFU/ml.

RESULTS

A mutans streptococci density score 3 was predominant both in saliva and on the mesial and occlusal surfaces of the first permanent molars. Scores 2 and 3 were predominant in younger children, while in 12-year-old children the four scores were in similar percentages.

CONCLUSION

High levels of mutans streptococci prevail among Iasi schoolchildren, highlighting the need to implement complex caries prevention programs.

摘要

目的

评估雅西学童口腔和唾液中变形链球菌的密度。

材料与方法

本横断面研究纳入了533名7至12岁的学童。按照制造商的说明，使用Dentocult SM Strip变形链球菌检测试剂盒（奥立安诊断公司）评估牙齿表面（第1、3恒磨牙的近中面和咬合面）及唾液中变形链球菌的密度。受试者被赋予以下分数之一：0 = < 10(4) CFU/ml；1 = < 10(5) CFU/ml；2 = 10(5) - 10(6) CFU/ml；3 = > 10(6) CFU/ml。
