Caries experience and gingival health in children and adolescents with type 1 diabetes mellitus-A cross-sectional study.

AIM: To investigate the oral health of children and adolescents with type 1 diabetes (T1D) and its associations with diabetes-related and lifestyle factors. DESIGN: Cross-sectional study at a large tertiary hospital pediatric diabetes clinic. Oral examination determined dental caries experience and gingival health. Secondary outcome measures included salivary characteristics, oral hygiene and dietary practices, and diabetes-related factors. RESULTS: Eighty children and adolescents with T1D participated; mean (SD) age and HbA1c were 13.4(2.6) years and 7.7(0.9)%, respectively. Forty-seven (59%) participants had one or more decayed, missing or filled teeth; 75 (94%) participants had gingivitis. Half (50%) reported ≥3 hypoglycemic episodes necessitating rapid-acting carbohydrate in the previous week. Sixty-two participants (78%) had normal saliva flow, however, 42 (52%) had reduced salivary buffering capacity. Glycemic control (HbA1c ) was not associated with caries experience, gingival health or salivary characteristics. Increased frequency of tooth brushing (OR, 0.11; 95%CI 0.01-0.97, p = 0.05) and interdental flossing (OR, 0.31; 95%CI 0.12-0.81, p = 0.02) were associated with lower caries experience. Interdental flossing (OR, 0.31; 95% CI 0.12-0.80, p = 0.02) and good oral hygiene (OR, 0.06; 95% CI 0.01-0.22, p < 0.001) were associated with less gingivitis. CONCLUSION: Poor oral health is common in children with T1D, regardless of HbA1c. Given potential implications for short- and long-term systemic health, this study demonstrates the need for targeted strategies to improve oral health in children with T1D.

Medical and dental characteristics of children with chromosome 22q11.2 deletion syndrome at the Royal Children's Hospital, Melbourne.

BACKGROUND: Chromosome 22q11.2 deletion syndrome (22q11.2DS) is a multifaceted syndrome with a variable phenotype. Few studies have described the associated dental characteristics and their relationship with medical co-morbidities; and no Australian data exist. AIM: To determine the clinical manifestations and correlations between oral and medical conditions in children with 22q11.2DS. DESIGN: A retrospective observational study. Children genetically diagnosed with 22q11.2DS at the Royal Children's Hospital Melbourne were selected; their medical and dental characteristics were collated and analysed. RESULTS: The study population (n = 57; mean age 11.5 years, range 2-27 years) experienced a range of medical conditions involving multiple medical systems; of whom 44 (77.2%) had caries experience, 7 (12.3%) developmentally missing teeth, and 31 (54.4%) developmental defects of enamel (DDE). Smaller proportions of primary teeth were affected by DDE in children with congenital heart disease (2.2% vs 9.7%; P = .02), and cardiac surgery (0.2% vs 9%; P = .001). Conversely, children with hypoparathyroidism (n = 2) had significantly higher proportions of primary teeth affected by DDE (27.5% vs 4%; P = .02). CONCLUSIONS: Significant associations existed between medical conditions (congenital heart disease, history of cardiac surgery, and hypoparathyroidism) and primary dentition DDE in children with 22q11.2 DS.

Cutaneous Mastocytosis in a Pediatric Dental Patient: Multidisciplinary Approach to Oral Management.

Mastocytosis is a heterogeneous disease of bone marrow origin, characterized by local or diffuse increased growth and accumulation of clonal mast cells in the skin and/or in internal organs. The skin is the organ most frequently involved, but others may be affected as well. The purpose of this article is to present the oral management of a child with urticaria pigmentosa/maculopapulous cutaneous mastocytosis requiring dental treatment under general anesthesia. The multidisciplinary team approach involving the relevant medical specialists is discussed to emphasize the significance of coordinated patient management.

Pattern and severity of early childhood caries.

OBJECTIVES: The aim of this study was to investigate the association between selected social and behavioural variables and the pattern and severity of early childhood caries (ECC) within a community child population. METHODS: A cross-sectional sample of 2515 children aged 4-5 years were examined in a preschool setting using decayed, missing, filled teeth/surface (dmft/dmfs) indices and a self-administered questionnaire was used to obtain information regarding social, demographic, birth, infant feeding, oral and general health attitudes. Children with caries (847) were divided into anterior or posterior caries pattern groups and severe (dmfs score > or =6) or non-severe (dmfs score <6) caries groups. The data were analysed using a chi-square test and modelled using a logistic regression procedure. RESULTS: Significant variables associated with anterior ECC pattern were ethnicity other than Caucasian (OR = 2.1, 95% CI = 1.4-3.1), sipping from the bottle during the day (OR = 1.9, 95% CI = 1.3-2.7), male gender (OR = 1.6, 95% CI = 1.2-2.2) and sleeping with a bottle at night (OR = 1.5, 95% CI = 1.1-2.2). Significant variables associated with severe ECC form were sipping from the bottle during the day (OR = 2, 95% CI = 1.4-2.8), maternal age at birth < or =24 years (OR = 1.8, 95% CI = 1.3-2.7), ethnicity other than Caucasian (OR = 1.6, 95% CI = 1.1-2.5) and sleeping with a bottle at night (OR = 1.5, 95% CI = 1.1-2.2). CONCLUSIONS: Infant bottle-feeding habits (either allowing a child to sip from a bottle during the day or put to sleep at night) and ethnicity other than Caucasian were significant determinants for both anterior caries pattern and severity of ECC in 4-5-year-old Australian children.

Early childhood caries and infant feeding practice.

OBJECTIVES: Early childhood caries (ECC) has been suggested as a new term to describe the presence of caries on at least one primary tooth in children under six years of age. The prevalence and severity of ECC in low socio-economic, immigrant and indigenous communities is high. The purpose of this study was to investigate the association between selected social and behavioural variables, including previous infant feeding practice, and the presence of ECC in an Australian child population. METHOD: A cross sectional sample of 3,375 four to six-year-old children from the north Brisbane region were examined in a school based setting using dmft/s indices and a self-administered questionnaire obtained information regarding social background and past infant feeding practice. The data were modelled using a forward stepwise logistic regression procedure to explore a statistical model for ECC presence. RESULTS: Significant determinants for ECC presence were ethnicity other than Caucasian (OR=1.99, CI=1.37, 2.88), language other than English (OR=1.97, CI=1.35, 2.86), single parent status (OR=1.93, CI=1.47, 2.52), sweetened bottle contents (OR=4.29, CI=2.90, 6.38), going to sleep with the bottle (OR=1.73, CI=1.49, 2.00) and sipping from the bottle during the day (OR=1.58, CI=1.35, 1.84). CONCLUSIONS: A statistical model for ECC presence and previous infant feeding practice has been constructed. This study supports the adoption of the proposed case definition of ECC.

Baseline dental plaque activity, mutans streptococci culture, and future caries experience in children.

PURPOSE: The purpose of this study was to evaluate a chairside caries risk assessment protocol utilizing a caries prediction instrument, adenosine triphosphate (ATP) activity in dental plaque, mutans streptococci (MS) culture, and routine dental examination in five- to 10-year-old children at two regional Australian schools with high caries experience. METHODS: Clinical indicators for future caries were assessed at baseline examination using a standardized prediction instrument. Plaque ATP activity was measured directly in relative light units (RLU) using a bioluminescence meter, and MS culture data were recorded. Each child's dentition was examined clinically and radiographically, and caries experience was recorded using enamel white spot lesions and decayed, missing, and filled surfaces for primary and permanent teeth indices. Univariate one-way analysis of variance between selected clinical indicators, ATP activity, MS count at baseline, and future new caries activity was performed, and a generalized linear model for prediction of new caries activity at 24 months was constructed. RESULTS: Future new caries activity was significantly associated with the presence of visible cavitations, reduced saliva flow, and orthodontic appliances at baseline (R(2)=0.2, P<.001). CONCLUSION: Baseline plaque adenosine triphosphate activity and mutans streptococci counts were not significantly associated with caries activity at 24 months.

Easy come, easy go: a simple and effective orthodontic enamel anchor for endotracheal tube stabilization in a child with extensive facial burns.

Endotracheal tube stabilization in patients with facial burns is crucial and often challenging. We present a simple method of securing an endotracheal tube using two orthodontic brackets bonded to the maxillary central incisor teeth and a 0.08'' stainless steel ligature wire. Our technique is less traumatic, and is easier to maintain oral hygiene than with previously described methods. This anchorage system takes 5 min to apply and can be removed on the ward without the need for a general anaesthetic.
