Oral health of children with type 1 diabetes mellitus: A systematic review

Ismail AF, McGrath CP, Yiu CK

Diabetes Res Clin Pract, 2015 Jun;108(3):369-81.
PMID: 25817182 DOI: 10.1016/j.diabres.2015.03.003

AIM: This systematic review investigated the oral health status of children with type 1 diabetes.
METHODS: A systematic search was conducted using PubMed/Medline, Web of Knowledge, SCOPUS and EMBASE. The search included all studies published from inception of database to January 2014. A total of 1179 abstracts were analyzed for selection in 2 phases. The first phase selection was based on the title and abstracts alone. The selected abstracts were then included for second phase, where full articles were obtained. The selection was carried out by 2 independent reviewers (Kappa value=0.809). Only 37 articles were included for final analysis in this review.
RESULTS: There is conflicting evidence in the caries experience between children with type 1 diabetes and healthy children. For periodontal health, most studies reported significantly greater plaque accumulation and higher gingival index in children with type 1 diabetes. Cohort studies reported no significant differences in perioodontal parameters over time.
CONCLUSIONS: There is conflicting evidence regarding the caries experience of children with type 1 diabetes, but they exhibit poorer periodontal health status with greater plaque accumulation compared to healthy children. Further studies are warranted to assess the oral health status of children with type 1 diabetes.

An in vitro study of a novel quaternary ammonium silane endodontic irrigant

Daood U, Parolia A, Elkezza A, Yiu CK, Abbott P, Matinlinna JP, et al.

Dent Mater, 2019 09;35(9):1264-1278.
PMID: 31201019 DOI: 10.1016/j.dental.2019.05.020

OBJECTIVE: To analyze effect of NaOCl+2% quaternary ammonium silane (QAS)-containing novel irrigant against bacteria impregnated inside the root canal system, and to evaluate its antimicrobial and mechanical potential of dentine substrate.
METHODS: Root canal was prepared using stainless steel K-files™ and ProTaper™ and subjected to manual and ultrasonic irrigation using 6% NaOCl+2% CHX, 6% NaOCl+2% QAS and saline as control. For confocal-microscopy, Raman spectroscopy and SEM analysis before and after treatment, Enterococcus faecalis cultured for 7 days. Raman spectroscopy analysis was done across cut section of gutta percha/sealer-dentine to detect resin infiltration. Indentation of mechanical properties was evaluated using a Berkovich indenter. The contact angle of irrigants and surface free energy were evaluated. Mineralization nodules were detected through Alazarin red after 14 days.
RESULTS: Control biofilms showed dense green colonies. Majority of E. faecalis bacteria were present in biofilm fluoresced red in NaOCl+2% QAS group. There was reduction of 484cm-1 Raman band and its intensity reached lowest with NaOCl+2% QAS. There was an increase in 1350-1420cm-1 intensity in the NaOCl+2% CHX groups. Gradual decrease in 1639cm-1 and 1609cm-1 Raman signal ratios were seen in the resin-depth region of 17μm>, 14.1μm> and 13.2μm for NaOCl+2% QAS, NaOCl+2% CHX and control groups respectively. All obturated groups showed an intact sealer/dentine interface with a few notable differences. 0.771 and 83.5% creep indentation distance for NaOCl+2% QAS ultrasonic groups were observed. Highest proportion of polar component was significantly found in the NaOCl+2% QAS groups which was significantly higher as compared to other groups. Mineralized nodules were increased in NaOCl+2% QAS.
SIGNIFICANCE: Favorable antimicrobial and endodontic profile of the NaOCl+2% QAS solution might suggest clinical use for it for more predictable reduction of intracanal bacteria.
Managing dental fear and anxiety in pediatric patients: A qualitative study from the public's perspective

Hamzah HS, Gao X, Yung Yiu CK, McGrath C, King NM

Pediatr Dent, 2014 Jan-Feb;36(1):29-33.
PMID: 24717706

PURPOSE:
Internet social media offers a rich source for soliciting the public's views on health issues. This qualitative research, using You-Tube as a platform, aimed to explore the public's perspectives on management of dental fear and anxiety (DFA) in pediatric patients.

METHODS:
Using three keywords ("dental fear," "dental phobia," and "dental anxiety"), YouTube videos were searched. Twenty-seven videos related to DFA in children and adolescents were reviewed by three investigators, including a nondental layperson. Inductive thematic analysis was adopted for interpreting the data.

RESULTS:
Several strategies were considered useful for controlling DFA in pediatric patients, including: verbal and nonverbal communication to establish closeness and effective guidance (explanation, permission-seeking, reassurance, and negotiation); desensitization to dental settings and procedures; tell-show-do; positive reinforcement; distraction by imagination and thoughtful designs of clinic; and parental presence and support. Some self-coping strategies adopted by patients alleviated their DFA, such as self-reasoning and trust-building through long-term connection. Dentists' clinical competence, favorable treatment outcomes, and state-of-the-art devices and technologies (dental lasers, intraoral camera, and adapted anaesthesia method) contributed to reducing DFA.

CONCLUSIONS:
Authentic testimonials in YouTube videos endorsed and interpreted a variety of strategies adoptable by patients, parents, and dental professionals for managing children's and adolescents' dental fears and anxieties.
