Overbite recognition and factors affecting esthetic tolerance among laypeople.

Objectives: To determine recognition ability and the levels of esthetic tolerance of deep bite and anterior open bite (AOB) among laypeople and investigate the factors affecting levels of tolerance.

Materials And Methods: Using a questionnaire, laypeople (N = 100) were examined, and overbite was measured. They were tested for whether they recognized deep bite and AOB.

Factors associated with burnout among dentists in public hospitals, southern Thailand.

Background/purpose: Physician burnout is now a public health crisis and dentist is a stressful professional health occupation. The purpose of this cross-sectional study was to determine the level of burnout and related factors among 423 Thai dentists working in public hospitals, southern Thailand.

Materials And Methods: A self-administered questionnaire was collected through an online platform and included 5 parts: general information, work information, 22-item Maslach Burnout Inventory-Human Services Survey (MBI-HSS), 23-item Thai Effort-Reward Imbalance Questionnaire (Thai ERIQ), and the Utrecht Work Engagement Scale-9 (UWES-9).

Self-perception of leadership style of dentists: heads of dental departments in community hospitals, Southern Thailand.

Introduction: Leadership is crucial in all professions and organisations, including the oral health profession.

Objectives: The aims of this analytical cross-sectional study were to evaluate the self-reported leadership behaviours and the factors influencing leadership behaviours among dentists who were heads of dental departments in community hospitals, southern Thailand.

Materials And Methods: The self-administered questionnaire was composed of four parts: personal data; a 45-item Multifactor Leadership Questionnaire version 5× short (MLQ 5× short); a 34-item organisational climate perception; and a 52-item emotional intelligence screening test.

Salivary lead in relation to caries, salivary factors and cariogenic bacteria in children.

Background: Saliva has been suggested as a useful biomarker of environmental contamination, including exposure to lead.

Aims: The study examined the associations between salivary lead level and the following factors: blood lead level, the number of decayed and filled surfaces (dfs) on deciduous and permanent teeth (DMFS), salivary flow rate, pH, buffer capacity, lactobacilli and mutans streptococci counts.

Materials And Methods: One hundred and twenty saliva samples of children living in a shipyard area (known to be an area contaminated with lead) were analysed for lead.

The periodontal health of lead-exposed children living in a shipyard industrial area.

In a cross-sectional design, 292 schoolchildren living around a shipyard area, known to be contaminated with lead from shipyard industry, were examined to verify the association between lead exposure and periodontal health. The probing pocket depth (PD), bleeding on probing, plaque and calculus, and the presence of Aggregatibacter actinomycetemcomitans (Aa) in subgingival crevices were recorded. Gingival inflammation was the most common (98%) among children in the area.

Chemical composition of enamel and dentine in primary teeth in children from Thailand exposed to lead.

Enamel and dentine in teeth of children with high blood levels of lead were analyzed by means of secondary ion mass spectrometry (SIMS) and X-ray micro-analyses (XRMA) and compare with teeth from children with low blood levels of lead. The SIMS analysis revealed detectable levels of Pb in dentine close to the pulp. The XRMA analyses could not detect any lead.

Microbiology in toothbrush samples from children exposed to lead in southern Thailand.

Objective: The purpose of this study was to evaluate the prevalence and level of selected oral bacterial species in association with dental caries in low versus high blood lead (PbB) children.

Material And Methods: With an observational cross-sectional design, a sample of 292 children aged 6-11 years from two primary schools around a shipyard, known to be an area contaminated with lead, were examined. The number of decayed and filled surfaces on deciduous teeth (dfs) and the number of decayed, missing, and filled surfaces on permanent teeth (DMFS) were recorded.

Morphology of enamel in primary teeth from children in Thailand exposed to environmental lead.

Lead is one of the major environmental pollutants and a health risk. Dental hard tissues have a capacity to accumulate lead from the environment. Eighty exfoliated primary teeth were collected from children residing around a shipyard area in southern Thailand, known for its lead contamination.

Lead associated caries development in children living in a lead contaminated area, Thailand.

In an observational cross-sectional design, a sample of 292 children aged 6-11 years from two primary schools around a shipyard area, known to be an area contaminated with lead (from the industry), were examined to verify the cariogenicity of lead. The number of decayed and filled surfaces on deciduous teeth (dfs), and the number of decayed, missing, and filled surfaces on permanent teeth (DMFS), the salivary flow rate, pH, buffer capacity, oral hygiene, Lactobacillus spp. and mutans streptococci counts were recorded.
