Presence of and in the oral cavity of a Northern Thailand population that experiences stomach pain.

: To investigate oral diseases and microbiological conditions, such as the presence of ureolytic bacteria in dental plaque, in relation to experience of stomach pain in a remote adult Asian population. : Ninety-three adults, 40-60-years old, from the Karen Hill tribe in Northern Thailand with no regular access to dental care were examined. Clinical registrations were performed and interproximal gingival plaque samples were collected and analyzed with the checkerboard (CKB) method for the presence of 14 oral bacterial species.

Periodontal disease in a remote Asian population: association between clinical and microbiological parameters.

Objective: The aim was to clinically and microbiologically describe the periodontal conditions in a remote adult Asian population with poor oral hygiene.

Methods: The subjects were 30-60-year-old adults of Karen Hill tribes with no access to dental care. Eighty-six subjects were selected randomly.

pH and bacterial profile of dental plaque in children and adults of a low caries population.

Objective: This study compares pH and microbiological profile of dental plaque in children and adults of a low caries population.

Material And Methods: Thirty-nine children, 12-14 years of age and 45 adults between 20 and 39 years of age in 5 Karen villages of the Tak province, Northern Thailand were examined for plaque, calculus, caries (DMFT) and pH measurements in resting plaque and after a sucrose rinse. Information on dietary and oral hygiene habits was obtained through interviews using a fixed questionnaire.

Dental plaque pH and ureolytic activity in children and adults of a low caries population.

Objectives: The aim of this study was to evaluate the plaque pH level and ureolytic activity among children and adults of Karen Hill tribes.

Methods: Thirty-four children aged 6-10 years and 46 adults aged 20-38 years were interviewed regarding oral hygiene practices, sucrose intake and betel chewing. Caries experience (DMFT and DT), calculus, bleeding on probing (BoP) and Plaque index (PlI) were registered.

Oral microflora in betel-chewing adults of the Karen tribe in Thailand.

Objective: To study a possible influence of betel chewing on the composition of the oral microflora in plaque and saliva and on oral health parameters as well as a possible betel effect on oral bacteria in vitro.

Material And Methods: Thirty-two adults (16 betel chewers and 16 non-betel-chewing controls) of the Karen Hill tribe in Thailand were investigated. Saliva samples and 2 pooled supragingival plaque samples were taken from each individual for microbial analysis with culture and 4 subgingival samples for analysis with the DNA-DNA hybridization method against 12 periodontitis associated bacterial species.
