MATERIALS AND METHODS: A cross-sectional study was done among 253 children of 5-, 12-, and 15-year-olds living in various orphanage houses of Selangor, Kuala Lumpur, Malaysia. Demographic data, and dietary and oral hygiene practices were collected through a structured questionnaire. Clinical examinations of children were conducted to assess oral health status and recorded in the World Health Organization oral health assessment form (1997). Stimulated saliva was collected for S. mutans and Lactobacilli levels. The statistical software, namely, Statistical Package for the Social Sciences version 19.0 was used for the analysis of the data.
RESULTS: The final data analysis included 253 children of which 116 (45.8%) were boys and 137 (54.2%) were girls. Overall, 140 (55.33%) children were caries-free and 113 (44.66%) children presented with caries (decayed/missing/filled surface >0). High levels of salivary microbiological counts (S. mutans and Lactobacilli), i.e., ≥105, stress the importance of necessary preventive oral health services. Treatment needs among orphan children showed that most of the children, i.e., 58 (22.9%), need preventive or caries-arresting care followed by 49 (19.4%) who require two-surface filling as an immediate measure.
CONCLUSION: From the results of our study, orphan children have low utilization of preventive and therapeutic oral health services. Urgent attention is required to plan a comprehensive dental health-care program to improve their oral health status.
CLINICAL SIGNIFICANCE: Parents are the primary caretakers of children, but woefully some of them have to lead their lives without parents, the latter either being dead or incapable of bringing up their children. Such a group of children is known as orphans. As oral health is an integral part of general health, it is essential for health-care policy makers to address oral health needs of this underprivileged group of society. This article highlights the risk factors and treatment needs among orphan schoolchildren.
MATERIALS AND METHODS: The literature search was performed for the studies published in the English language independently by all four authors (search team) in the Medline database through the PubMed search engine for the past 5 years. The study involved predetermined inclusion and exclusion criteria for the search. The final lists of clinical trials were analyzed to determine the existing evidence and suggested the mechanism of action.
REVIEW RESULTS: The search resulted in 117 titles. After application of inclusion and exclusion criteria, a total of seven studies were found eligible for this systematic review. Out of seven, two studies were found eligible for meta-analysis whereas remaining included for the systematic review.
CONCLUSION: The meta-analysis favors socket grafting compared to control in terms of preservation of existing bone height and width. The SHA grafting showed successful bone regeneration with less connective tissue component. The histomorphometric evaluation showed a good bone regeneration associated with SHA than xenograft. Within the limitations of this meta-analysis, the synthetic GSM can be used for socket grafting.
CLINICAL SIGNIFICANCE: In the wake of increasing graft materials in the market and different origin raw material sources for the preparation of graft materials, clinicians are in dilemma for selection and its use. The success of grafting depends on the selection of appropriate material with a suitable calcium/phosphate (Ca/P) ratio. The review provided available evidence for the use of SHA.
RESULTS: Minimal inhibitory concentration was determined at 0.625% of the concentration of ACV against S. mutans and E. faecalis and 1.25% of the concentration of ACV against L. casei with two-fold serial dilutions. A concentration of 5 × 10-1% with 10-fold serial dilutions was found to be the MIC value for all three bacteria. No significant differences were found when compared with the positive control (NaOCl) (p = 0.182, p = 0.171, and p = 0.234), respectively, for two-fold serial dilutions and (p = 1.000, p = 0.658, and p = 0.110), respectively for 10-fold serial dilutions. MBC was observed to be 5% ACV for both E. faecalis and S. mutans. However, positive microbial growth was observed on the agar plate when cultured with L. casei. An independent sample t-test showed no significant differences (p > 0.05) in the antimicrobial activities between 5% ACV and 5% pure AA. TEM revealed cell wall and cytoplasmic membrane disruptions on all three bacteria at MIC value.
CONCLUSION: Apple cider vinegar has antimicrobial activities against Enterococcus faecalis, Streptococcus mutans, and Lactobacillus casei at their respective MIC values.
CLINICAL SIGNIFICANCE: Apple cider vinegar can be an alternative antimicrobial dental pulp disinfectant to sodium hypochlorite. Apple cider vinegar can be used safely, especially in children's dental pulp therapy and deep caries management, when adequate tooth isolation is not readily achievable. Thus, adverse reactions commonly associated with other frequently used chemical disinfectants can be avoided.
MATERIALS AND METHODS: This prospective cross-sectional study comprised 78 growing children in the age range of 11-14 years with polysomnography (PSG)-proven OSA and 86 non-OSA corresponding controls. BMI, tonsil size (Friedman grading scale), and Mallampati score were determined for both groups, and related differences were assessed with a t-test, while their independent association with OSA severity was tested with a regression analysis. Statistical significance was set at p <0.05.
RESULTS: Male gender, BMI, tonsil size, and Mallampati score were significantly higher in the OSA group (p < 0.05). A significant correlation was recorded between the Mallampati score and OSA severity (p < 0.01), but not with BMI or tonsil size (p > 0.05). For every 1-point increase in the Mallampati scale, the apnea-hypopnea index (AHI) increased by more than five events per hour in the bivariate analysis and by more than three events per hour in the multivariate analysis.
CONCLUSION: Male gender, increased BMI, high tonsil, and Mallampati scores were clinical indicators of the presence of OSA. However, only Mallampati scale had a significant association with OSA severity. Clinical diagnostic indicators should be established and encouraged especially in community-based studies.
CLINICAL SIGNIFICANCE: Clinical diagnostic indicators are very useful in examining and screening children who are at risk of developing OSA as PSG is expensive and unsuitable for universal use in the pediatric population.
BACKGROUND: Literature lacks information on various unsplinted attachment systems and their effect on peri-implant tissue health. A focus question (as per PICOS) was set as follows: Does one particular unsplinted attachment system (I) compared with another (C) results in better peri-implant outcomes (O) in two implant-retained mandibular overdentures (P) using randomized controlled trials (RCTs) (S)? The literature search was conducted in the PubMed, MEDLINE and Cochrane Central Register of Controlled Trials (CENTRAL) databases between January 2011 and December 2021. The keywords used were "denture, overlay," "denture," "overlay" AND "dental prosthesis, implant supported," "dental implants," "dental implant abutment design" AND "jaw, edentulous," "mouth, edentulous" AND "mandible." Only RCTs on two implant-retained mandibular overdentures using unsplinted attachment systems measuring peri-implant tissue outcomes with minimum 1-year follow-up were selected. In total, 224 studies were identified in initial search, and 25 were shortlisted for full-text evaluation. Four studies were included for systematic review upon considering inclusion and exclusion criteria. The risk of bias was evaluated using Cochrane Risk of Bias Tool 2.0 (RoB 2.0).
REVIEW RESULTS: A total of 41 patients received ball attachments (in 3 studies), 36 patients received low-profile attachments (in 3 studies), 16 patients received magnet attachments (in 1 study), and 13 patients received telescopic attachments (in 1 study). All four studies used standard sized implants, however, differed in implant manufacturers. Two studies which compared ball attachments low-profile attachments revealed-similar peri-implant tissue health parameters but differed in crestal bone-level changes. One study compared ball with telescopic attachments and revealed similar results in crestal bone-level changes and all four peri-implant tissue health parameters. Single study compared magnets with low-profile attachments and shown lesser bone loss with magnet attachments. Single study was judged to have low risk of bias, single with some concerns, and remaining two to have high risk of bias.
CONCLUSION: Gingival index and bleeding index of the patients were not influenced by any of the unsplinted overdenture attachment (stud, magnet, telescopic) system. Inconclusive results found among the studies evaluated comparing crestal bone loss and plaque index.
CLINICAL SIGNIFICANCE: This review manuscript has simplified comparative analysis of different unsplinted attachment systems used in two implant mandibular overdentures to help clinicians choose correct system in such situation.
