and in a Kenyan Maasai Adolescent Population and Inhibition of Leukotoxic Activity by Herbal Plants Used as Part of Oral Hygiene Procedures.

Background: A virulent genotype (JP2) of the periodonto-pathogen, (), is widespread in North and West Africa, while its presence in East Africa has not been thoroughly investigated. This JP2 genotype is associated with periodontitis in adolescents and has a high leukotoxicity. The aim of the study was to examine the prevalence of and its JP2 genotype, the prevalence of the oral, commensal in a Maasai adolescent population, and the effect of herbal plants for inhibition of leukotoxicity.

Prevalence of JP2 and Non-JP2 Genotypes of and Oral Hygiene Practice of Kenyan Adolescents in Maasai Mara.

is implicated in the etiology of periodontitis that affects adolescents. The monitoring and mapping of the geographic dissemination pattern of JP2 and non-JP2 genotypes of are of interest. In Africa, the highly leukotoxic JP2 genotype is known to be prevalent, particularly in north-west Africa.

Prevalence and impact of infant oral mutilation on dental occlusion and oral health-related quality of life among Kenyan adolescents from Maasai Mara.

Background: Infant Oral Mutilation (IOM) includes germectomy and early extraction of primary and permanent incisors and canines, primarily in the lower jaw. The aim of the present study was to examine the prevalence and impact of IOM, involving the removal of mandibular permanent incisors and/or canines, on dental occlusion and Oral Health-Related Quality of Life (OHRQoL) among Kenyan adolescents from Maasai Mara.

Methods: In a cross-sectional study, 284 adolescents (14-18 yrs.

Association of salivary RANKL and osteoprotegerin levels with periodontal health.

The aim of this study is to determine the association of salivary levels of the bone remodelling regulators (RANKL) and osteoprotegerin (OPG) with periodontal clinical status. One-hundred fifty-eight participants selected from a pool of adult patients via systematic random sampling were included in this descriptive cross-sectional study carried out at the University of Nairobi Dental Hospital. About 5 ml of unstimulated whole saliva was collected from each participant followed by periodontal clinical examination.

Transcriptomic analysis of three Veillonella spp. present in carious dentine and in the saliva of caries-free individuals.

Veillonella spp. are predominant bacteria found in all oral biofilms. In this study, a metatranscriptomic approach was used to investigate the gene expression levels of three oral Veillonella spp.
