Multiple Developmental Dental Anomalies in a Nonsyndromic Patient: A Rare Case Report.

The present case report illustrates a rare occurrence of multiple dental anomalies in a healthy 12-year-old patient including anomalies of shape and number of teeth. The developmental dental anomalies noticed in the present case scenario are dens invaginatus, taurodontism, radix entomolaris, supernumerary teeth, and pulp stones seen in multiple teeth. It is not rare to notice these anomalies individually, but their combination is rare in a single, non-syndromic patient. This report also signifies the importance of thorough extra-intra-oral and radiographic examinations of patients with dental anomalies.

A Prospective Study on Assessment of Microbial Contamination of Toothbrushes and Methods of Their Decontamination.

BACKGROUND: Toothbrushes may get contaminated by the oral cavity, environment, hands, storage containers, or aerosol contamination. The present study was conducted to assess the microbial contamination of toothbrushes and methods of their decontamination. MATERIALS AND METHODS: The current study included 160 subjects of both genders. All the subjects were provided with a toothbrush and paste with complete hygiene instructions for the oral cavity. After one month, all the brushes were collected. The samples were categorized into four groups of 40 each. Group I was treated with 0.2% chlorhexidine gluconate, group II with Listerine, group III with Dettol, and group IV with tap water. Finally, these toothbrushes were placed in 5 mL of neutralizer broth and then evaluated to study the efficacy of four disinfectants. All the data were analyzed using the statistical package for social science (SPSS) version 23 software (IBM, Armonk, NY, USA). For all analyses, p < 0.05 was considered to be statistically significant Results: Aerobic bacterial growth before disinfection in Groups I, II, III, and IV was 91.6%, 75.84%, 75%, 81.67%, respectively (p = 0.01). After disinfecting the brushes aerobic bacterial growth was reduced to 34.17%, 30.84%, 24.17% & 74.17% in Groups I, II, III, and IV, respectively (p = 0.002). Klebsiella, Micrococci and Escherichia coli survived the most even after disinfection was done. CONCLUSION: Most effective agent for the disinfection of toothbrushes was Dettol followed by Listerine and 0.2% chlorhexidine gluconate. Tap water was found to be ineffective in the decontamination of toothbrushes.
