Summary.  Chronic hepatitis C patients are advised not to share toothbrushes, razors, nail‐scissors or other personal articles that potentially may have been in contact with blood, with others. This study examines the contamination of toothbrushes in patients with chronic hepatitis C as a model for a possible unconventional way of transmission. In 30 patients with chronic hepatitis C, 2 mL of saliva (before and after toothbrushing) and the toothbrush rinsing water after toothbrushing were… 

HEPATITIS B AND C IN DENTISTRY

TLDR
Dentists were in a high risk of contracting this disease due to the procedures and instruments of dental treatment, and patients with liver disorders are of significant interest to the dentist because liver plays a vital role in metabolitic function.

Microbial Contamination of Toothbrush Bristles among Gingivitis and Periodontitis: An in vitro study

TLDR
From the study it can be inferred that microbial contamination was higher in periodontitis patients' bristles than the gingivitis, indicating increased microbial contamination after the initial use and increases with repeated usage.

MICROBIOLOGICAL ANALYSIS OF IN-USE TOOTHBRUSHES AND THEIR DECONTAMINATION USING DISINFECTION: A HOSPITAL BASED PILOT STUDY

TLDR
In-use toothbrushes become highly contaminated after use and can act as fomites for transmitting infections and proper instructions for use of toothbrushed should be given to patients and public.

Bacterial Contamination of the Toothbrushes

TLDR
The microbiological findings showed a high contamination of the used toothbrushes at 100% of the analyzed samples, with a domination of coliform bacilli, and Toothbrushes became highly contaminated after everyday use.

Highlights for Dental Care as a Hepatitis C Risk Factor: A Review of Literature

TLDR
In developed nations, general dental care does not appear to be a significant risk factor for HCV transmission in non-intravenous drug user patients; although, the improper use and reuse of anesthetics during procedures poses a rare potential risk for viral transmission.

Evaluation of microbial contamination and efficacy of antimicrobial agents in disinfection of handicapped patients’ toothbrushes

TLDR
Evaluated the contamination of toothbrushes used by patients with disabilities, by microbial culture and cariogenic biofilm formation, and to explore two methods of disinfection found both 0.12% chlorhexidine and cetylpyridinium chloride spray solutions can effectively be used for toothbrush disinfection to reduce contamination.

The Frequency of Hepatitis C and its Risk Factors Among Health Care Providers at Tehsil Headquarter Hospital, Hasilpur, Pakistan

TLDR
The frequency of HCV among health care providers is high and awareness programs and training workshops should be mandatory to increase knowledge about hepatitis C prevention to decrease the incidence of hepatitis C infection among health Care workers.

Hepatitis C virus and dental health workers: an update.

TLDR
A review of HCV epidemiology, natural history, transmission, diagnosis, treatment and prevention focusing on oral manifestations in and dental management strategies for HCV-infected individuals is performed.

Bacterial and viral pathogens in saliva: disease relationship and infectious risk

Research on the infectious aspects of dental diseases has focused on the internal development and the pathogenicity of dental biofilms, and comparably little attention has been given to the source of

Prevalence and risk factors for intrafamilial transmission of hepatitis C virus in Karachi, Pakistan

TLDR
The final multivariable conditional logistic regression model revealed that the HCV‐seropositive household contacts were more likely than HCV seronegative household contacts to have been bitten by the carrier or have shared a toothbrush with the carrier.

Hepatitis C virus infection in institutionalized psychiatric patients: possible role of transmission by razor sharing.

The objective of this study was to determine if HCV can be transmitted from patient to patient in psychiatric institutions and to determine possible routes of infection. We did a cross-sectional

Prevention of spread of hepatitis C

TLDR
The primary prevention of illegal drug injecting will eliminate the greatest risk factor for HCV infection in the United States and other prevention strategies that need to be widely implemented include risk reduction counseling and services and review and improvement of infection control practices in all types of health care settings.

Failure to detect hepatitis C virus genome in human secretions with the polymerase chain reaction

TLDR
Seroepidemiological studies indicating that nonparenteral transmission of hepatitis C through secretions is uncommon and probably much less efficient than hepatitis B virus infection are supported.

Detection of HCV-RNA in saliva of patients with chronic hepatitis C.

TLDR
These results provide a biological basis for saliva as a possible source of hepatitis C virus (HCV) infection, but do not necessarily imply transmission by this route.

TLDR
It was thought for many years that successful motivation in oral health should be based on the knowledge of epidemiology of caries and periodontal diseases and the methods of prevention, but these are not used by the majority although they provide a pronounced reduction of carie and gingivitis.

Classification of chronic hepatitis: Diagnosis, grading and staging

TLDR
Recombinant human alpha-interferon in patients with chronic nonA-nonB hepatitis and factors predictive of response to interferon alpha therapy in HCV infection are studied.
