Could polyhexanide and chlorine dioxide be used as an alternative to chlorhexidine? A systematic review

ABSTRACT BACKGROUND: Maintenance of oral microbiota balance is the simplest way to prevent infectious oral diseases, through controlling dental biofilm. Combined use of mouthwash and mechanical removal has been shown to be a very effective way for this. OBJECTIVES: To identify clinical studies comparing the antimicrobial effect and possible adverse effects and/or side effects of chlorhexidine-based mouthwashes with those of mouthwashes containing chlorine dioxide and/or polyhexanide, for controlling oral microbiota. DESIGN AND SETTING: Systematic review designed by the stomatology sector of postgraduation in applied dental sciences of Bauru Dentistry School, University of São Paulo, Brazil. METHODS: A systematic review was conducted using online databases (PubMed, Embase, Web of Science and Science Direct) up to April 8, 2020. The search was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. RESULTS: The studies included comprised eight articles published between 2001 and 2017. A total of 295 young adults, adults and elderly people were evaluated (males 44.75% and females 55.25%). Three articles compared polyhexanide with chlorhexidine and five articles compared chlorine dioxide with chlorhexidine. No studies comparing all three mouthwashes were found. The concentrations of the study solutions were quite varied, and all rinses had an antimicrobial effect. In four studies, it was stated that no side effects or adverse effects had been found. Three studies did not address these results and only one study addressed side effects and/or adverse effects. CONCLUSION: Mouthwashes containing chlorine dioxide and polyhexanide are viable alternatives to chlorhexidine, since they reduce oral biofilm and have little or no reported side or adverse effects.

Poor Oral Health Increases the Physical Pain, Psychological Discomfort and Social Incapacity of Individuals with Oncohaematological Diseases / La Mala Salud Oral Aumenta el Dolor Físico, el Malestar Psicológico y la Incapacidad Social de las Personas con Enfermedades Oncohematológicas

The objective of this study was to evaluate the relationship between oral health status and its impact on quality of life, and to suggest dental management strategies in patients undergoing antineoplastic therapy for onco-hematological diseases. A retrospective study including 33 individuals (age 9-79 yr) was conducted. It was observed that the dimensions related to physical pain, psychological discomfort, and social incapacity had statistically significant values. The most frequently performed dental treatments were periodontal treatment (45.45 %), dental restoration (36.36 %), tooth extractio n (33.33 %), and endodontic treatment (24.24 %). Thus, poor oral health directly affects the quality of life. Dental management should consider the aspects of the disease and antineoplastic treatment while aiming for safe and effective dental care.

El objetivo de este estudio fue evaluar la relación entre el estado de salud oral y su impacto en la calidad de vida, y sugerir estrategias de manejo odontológico en pacientes sometidos a terapia anti-neoplásica por enfermedades onco-hematológicas. Se realizó un estudio retrospectivo que incluyó a 33 personas (de 9 a 79 años de edad). Se observó que las dimensiones relacionadas con dolor físico, malestar psicológico e incapacidad social tuvieron valores estadísticamente significativos. Los tratamientos dentales realizados con mayor frecuencia fueron el tratamiento periodontal (45,45 %), la restauración dental (36,36 %), la extracción dentaria (33,33 %) y el tratamiento endodóntico (24,24 %). Así, la mala salud oral afecta directamente la calidad de vida. El tratamiento dental debe tener en cuenta los aspectos de la enfermedad y el tratamiento antineoplásico mientras se busca una atención dental segura y eficaz.
