Abstract

Globally, it is estimated that 2 billion people suffer from caries of permanent teeth and 520 million children suffer from caries of primary teeth. Bacteria such as Streptococcus mutans, and Lactobacilli are among the most common pathogens that mostly cause tooth decay. There are an estimated more than 1.5 million cases of tooth decay reported in Nigeria yearly, which occur in all individuals at apparently no age preferences. Tooth decay normally results in serious pain, infections, and loss of teeth if not properly treated. The present study aims to determine the presence of Streptococcus mutans causing tooth plaque from patients attending Murtala Muhammed Specialist Hospital, Kano State Nigeria. A total of 400 samples of oral dental plaque were collected and processed using standard microbiological procedure; include culture, Gram stain, catalase test, optochin susceptibility screening test and confirmed to the species level by Analytical Profile Index 20 Strep (API 20 Strep). Confirmed, S. mutan were subjected to antimicrobial susceptibility test against some common antibiotics. Of 400 samples enrolled 87.8% (351/400) shows positive bacterial growth and 87 was confirmed to be S. mutan. Great antimicrobial activity was observed to linezolid, clindamycin and ciprofloxacin against the isolated S. mutan.
