Childhood dental injuries: a resiliency model of adaptation
There is a paucity of research examining how children and their families adapt to traumatic dental injuries. This study examined how clinical and psychosocial factors influence adaptation to this oral stressor using a theoretical framework of resiliency and adaptation. Children with traumatised permanent teeth, who were attending a UK dental hospital, completed questionnaires at baseline and at...


Lactoferrin levels in gingival crevicular fluid and saliva of HIV-infected patients with chronic periodontitis
This study compared lactoferrin (LF) levels in the gingival crevicular fluid (GCF) and saliva between HIV-infected and noninfected patients with chronic periodontitis. For each subject, LF levels were analyzed in one shallow site (SS; PD ≤3 mm), one deep site (DS; PD >5 mm) and in resting whole saliva. Two groups, 28 HIV-infected and 10 noninfected, were selected. Although the salivary LF l...
Validation of Persian rapid estimate of adult literacy in dentistry
The aim of the present study was to establish the psychometric properties of the Rapid Estimate of adult Literacy in Dentistry-99 (REALD-99) in the Persian language for use in an Iranian population (IREALD-99). A total of 421 participants with a mean age of 28 years (59% male) were included in the study. Participants included those who were 18 years or older and those residing in Quazvin (a c...


Long-term follow up of post-surgical tooth autotransplantation: a retrospective study
The aim of the present retrospective study was to evaluate the long-term results of tooth autotransplantation using the survival and success rates of transplanted teeth as outcome variables. Thirty patients received a total of 44 transplants of immature teeth from 1987 to 1997. Seventeen of those patients with 25 transplants were recalled 10–20 years after tooth transplantation for complete ...
Effect of surface roughness on the hydrophobicity of a denture-base acrylic resin and Candida albicans colonization
The aim of the present study was to evaluate the effect of surface roughness (roughness average [Ra] μm) on the hydrophobicity of a denture-base acrylic resin and the initial adherence and biofilm formation of Candida albicans (C. albicans). Disk-shaped specimens were divided into six groups: Ra 0.05, Ra 0.2, Ra 0.4, Ra 0.8, Ra 1.5, and Ra 3.0. Water contact angles (WCA) were measured, and th...


Attitude toward rapid HIV testing in a Dental School Clinic
Detection of HIV infection provides an opportunity for transmission reduction and lifesaving treatment strategies. This study examined patients’ willingness to take a routine, rapid oral HIV test if offered at a dental school clinic. For fifteen days in 2011, an anonymous survey containing demographic information and willingness to be tested questions was offered to all patients awaiting trea...
Qualitative description of dental hygiene practices within oral health and dental care perspectives of Mexican-American adults and teenagers
The objectives of this study were to identify dental hygiene themes voiced by adults and teenagers of Mexican origin [or Mexican Americans (MAs)] and place these themes within the larger landscape of oral health and dental care perceptions. Interviews with urban-based MAs were analyzed to identify barriers, beliefs, and behaviors influencing engagement in dental hygiene practices. Adult (n =...

Associations of apolipoprotein E and low-density lipoprotein receptor-related protein 5 polymorphisms with dyslipidemia and generalized aggressive periodontitis in a Chinese population
Dyslipidemia is associated with aggressive periodontitis, a condition characterized by the rapid destruction of the periodontium. Apolipoprotein E (APOE) and low-density lipoprotein receptor-related protein 5 (LRP5) are involved in immunomodulation and inflammatory activity. We evaluated the association of LRP5 and APOE polymorphisms with serum lipid concentrations and generalized aggressive pe...
Cellular composition of long-standing gingivitis and periodontitis lesions
Insufficient information on the cellular composition of long-standing gingivitis lesions without signs of attachment loss makes an understanding of differences in cellular composition between “destructive” and “nondestructive” periodontal lesions difficult. The aim of the current study was to analyze differences in cell characteristics between lesions representing long-standing gingivit...

Occurrence and impact of xerostomia among dentate adult New Zealanders: findings from a national survey
We investigated the prevalence, associations and impact of xerostomia in a nationally representative sample of dentate adult community-dwelling New Zealanders aged 18 years and above. The data were collected from a representative sample of 2209 adults, as part of the 2009 New Zealand Oral Health Survey (NZOHS). Data were collected using face-to-face interviews, dental examinations and the short...
Effect of a novel bioactive glass-ceramic on dentinal tubule occlusion: an in vitro study
This in vitro study aimed to assess the ability and efficacy of HX-BGC, a novel bioactive glass-ceramic (SiO2-P2O5-CaO-Na2O-SrO), to reduce dentine tubule permeability. Dentine discs from human third molars were etched and randomly allocated into five groups: Group 1 – distilled water; Group 2 – Sensodyne Repair toothpaste (containing NovaMin®); Group 3 – HX-BGC toothpaste (containing 7....

The effect of lifetime fluoridation exposure on dental caries experience of younger rural adults
The aim of this study was to confirm whether the level of lifetime fluoridation exposure is associated with lower dental caries experience in younger adults (15–46 years). Data of the cohort born between 1960 and 1990 residing outside Australia's capital cities from the 2004−2006 Australian National Survey of Adult Oral Health were analysed. Residential history questionnaires were used to d...
Effect of QMix irrigant on the microhardness of root canal dentine
The aim of this study was to evaluate the effects of QMix, EDTA + CHX, EDTA + NaOCl and maleic acid on the microhardness of root canal dentine. Forty recently extracted human maxillary canine teeth were longitudinally sectioned into 80 segments and then embedded in an autopolymerizing acrylic resin. The microhardness of the dentine in the specimen was measured with a Vickers diamond indenter at...
Ameloblastoma: demographic data and treatment outcomes from Melbourne, Australia
There is a lack of published data on the demographics and treatment outcomes of ameloblastomas treated in Australia. Our objective was to collect this data and compare the findings to other international studies. A retrospective study of 42 patients with ameloblastoma was conducted at The Royal Melbourne Hospital, Australia. Data on the demographic features, management techniques (ablative and ...
Water fluoridation, dentition status and bone health of older people in Ireland
To examine some of the potential benefits and risks of water fluoridation for older adults. This study used ‘The Irish Longitudinal Study on Ageing’, to access a nationally representative sample of 4977 people aged 50 and older. The sample was used to estimate associations between the percentage of households in a respondent's local area with a currently fluoridated water supply and the pro...
