Regenerative endodontic therapy: a follow-up of 47 anterior traumatised teeth.

Eur Arch Paediatr Dent 2021 Jun 27;22(3):469-477. Epub 2020 Nov 27.

Paediatric REsearch Project (PREP), Barneveld, Nederland.

Purpose: To collect long-term survival data in anterior traumatised teeth on the outcome of Regenerative Endodontic Treatments (RET) with a network of dentists working in different clinics to overcome the problem of anecdotical evidence.

Methods: The seven dentists from Paediatric REsearch Project (PREP) performed RET treatments following the same protocol in five different secondary dental care clinics in the Netherlands. Treatment resulting in pain, apical problems, sinus tracts, resorption or fracture were considered as failure of treatment.

Results: 47 teeth in 38 children were treated between January 2009 and September 2017 and had at least 6 month follow-up (mean 35 months). Apical closure was seen in 27 teeth (25 cases) and root length growth in 6 teeth (6 cases). Thickening of the root walls was seen in 20 teeth (20 cases) and obliteration of the root canal in 30 teeth (25 cases). Of 38 teeth with apical inflammation at the start of treatment, no radiographic sign of apical inflammation was visible at 3 months in 13 of 28 teeth; taking up to 42 months for radiographic signs of apical inflammation to be not visible. Nineteen of 35 teeth showed discoloration at the beginning of treatment. After 18 months two teeth showed signs of ankylosis, but were still functional. After 36 months one more tooth showed signs of new apical inflammation and 2 months later it was extracted.

Conclusions: With three failures in 47 treated teeth, RET seems to be a promising treatment for difficult to treat anterior traumatised teeth with an open apex.

Barriers and opportunities to oral health in Dutch-Moroccan children in the Netherlands: a narrative report.

Eur Arch Paediatr Dent 2018 Oct 20;19(5):353-364. Epub 2018 Aug 20.

Department of Public health and Primary Care, Leiden University Medical Centre (LUMC), Postbus 9600, 2300 RC, Leiden, The Netherlands.

Introduction: Previous studies showed that 5-year-old Dutch-Moroccan children had significantly higher dmft scores compared to Dutch children of the same age, even after correction for socio-economic status. The mechanisms underlying this difference are little understood.

Aim: To explore cultural factors involved in poorer oral health of Dutch-Moroccan children by identifying knowledge, attitudes and behaviour of their mothers concerning their children's oral health.

Methods: In 2012 mothers of Dutch-Moroccan preschool children in two cities in the Netherlands were interviewed in two focus groups (n = 16) or individual semi-structured interviews (n = 13). Semi structured interviews were also c onducted with three oral health professionals, working with Dutch-Moroccan children, and one physician from an under-five-clinic. All interviews were voice recorded, transcribed and inductively coded. MAXQDA software was used for data analysis.

Results: All mothers mentioned pain complaints, swelling and black front teeth as oral health problems in their children. Although mothers were aware that brushing teeth and reducing sugary snacks are effective preventative strategies, they did not sufficiently implement these measures. This was due to lack of brushing skills, insufficient awareness of the daily sugar intake of their children and their childrearing concerning these measures. Most mothers indicated they felt empowered in making dental care decisions.

Conclusions: This research revealed the presence of knowledge on preventive strategies regarding their children's oral health in Dutch-Moroccan mothers, but an inadequate implementation of these measures in their daily lives. Additional qualitative research is needed to gain deeper insight for broader exposure of values, knowledge and culture.

A study of parental presence/absence technique for child dental behaviour management.

Eur Arch Paediatr Dent 2017 Dec 16;18(6):405-409. Epub 2017 Nov 16.

Department of Paediatric Dentistry, School of Dentistry, Aristotle University of Thessaloniki, Papafi 88, 54453, Thessaloniki, Greece.

Aim: To examine the effectiveness of parental presence/absence (PPA) technique on the dental behaviour management of children.

Materials And Methods: This randomised control study recruited 61 child dental patients with uncooperative behaviour (Frankl 1 or 2) managed with AAPD-endorsed non-pharmacological techniques at a post-graduate university clinic. PPA was only used in the test group (31 children). Using a mini video-tape device, recording commenced at the onset of uncooperative behaviour and this was later rated, minute by minute, by a blinded experienced paediatric dentist.

Statistical Analysis: Data were analysed with SPSS v.13.0. The Kolmogorov-Smirnov test was used for normality analysis. The Mann-Whitney U-test and Log Rank analysis were also performed.

Results: The mean point in time, after behavioural problems commenced that PPA or alternatives were applied was 1.82 ± 1.04 min. Behaviour improvement (technique success) was shown by 65.6% of all children. There was no statistically significant difference between the study and control groups in age, gender, mean Frankl score, in Frankl score 2 min before/after technique application or regarding the time point at which the technique was first applied. Behaviour improvement was seen in 17 patients (54.8%) in the PPA group and in 23 patients (76.7%) in the control group.

Conclusion: PPA applied to various dental sessions as a behaviour management technique showed no advantage over other basic, non-pharmacological techniques.

Dental fear and caries in 6-12 year old children in Greece. Determination of dental fear cut-off points.

Eur J Paediatr Dent 2017 Mar;18(1):45-50

Department of Cariology, Endodontology and Pedodontology, ACTA Amsterdam, The Netherlands.

Aim: To present: the normative data on dental fear and caries status; the dental fear cut-off points of young children in the city of Thessaloniki, Greece.

Methods: Study Design: This is a cross-sectional study with two independent study groups. A first representative sample consisted of 1484 children from 15 primary public schools of Thessaloniki. A second sample consisted of 195 randomly selected age-matched children, all patients of the Postgraduate Paediatric Dental Clinic of Aristotle University of Thessaloniki. First sample: In order to select data on dental fear and caries, dental examination took place in the classroom with disposable mirrors and a penlight. All the children completed the Dental Subscale of the Children's Fear Survey Schedule (CFSS-DS). Second sample: In order to define the cut-off points of the CFSS-DS, dental treatment of the 195 children was performed at the University Clinic. Children⁁s dental fear was assessed using the CFSS-DS and their behaviour during dental treatment was observed by one calibrated examiner using the Venham scale.

Statistics: Statistical analysis of the data was performed with IBM SPSS Statistics 20 at a statistical significance level of <0.05.

Results: First sample: The mean CFSS-DS score was 27.1±10.8. Age was significantly (p<0.05) related to dental fear. Mean differences between boys and girls were not significant. Caries was not correlated with dental fear. Second sample: CFSS-DS< 33 was defined as 'no dental fear', scores 33-37 as 'borderline' and scores > 37 as 'dental fear'. In the first sample, 84.6% of the children did not suffer from dental fear (CFSS-DS<33).

Conclusion: Dental fear was correlated to age and not to caries and gender. The dental fear cut-off point for the CFSS-DS was estimated at 37 for 6-12 year old children (33-37 borderlines).

Relationship between Child and Parental Dental Anxiety with Child's Psychological Functioning and Behavior during the Administration of Local Anesthesia.

J Clin Pediatr Dent 2016 ;40(6):431-437

Objectives: The aims of this study were to determine: 1) the relationship between children's psychological functioning, dental anxiety and cooperative behavior before and during local anesthesia, 2) the relationship of parental dental anxiety with all the above child characteristics.

Study Design: There was a convenient sample of 100 children (4-12 years). Child dental anxiety and psychological functioning were measured using the "Children's Fear Survey Schedule" (CFSS-DS) and the "Strengths and Difficulties Questionnaire" (SDQ) respectively. Parental dental anxiety was measured using the "Modified Dental Anxiety Scale" (MDAS). All questionnaires were completed by parents. Before and during local anesthesia, the child behavior was scored by one experienced examiner, using the Venham scale. Non-parametric tests and correlations (Mann-Whitney, Spearman's rho) were used for the analysis.

Results: The mean SDQ score was 10±5.6 for boys (n=60) and 8.3±4.8 for girls (n=40) (p=0.038), but there was no correlation with children's age. The mean CFSS-DS score was 33.1±11.86 and there was no correlation with age or gender. Children with higher levels in the pro-social subscale of the SDQ had significantly less anxiety and better behavior before local anesthesia. Higher mean CFSS-DS scores were significantly associated with uncooperative behavior during local anesthesia (p=0.04). There was no correlation between parents' and their children's dental anxiety, psychological functioning and behavior. 46% of the children had previous dental experience in the last 6 months. As time since the last dental treatment increased, an improvement was found in children's behavior during local anesthesia.

Conclusions: Child psychological functioning was related to dental anxiety and behavior during dental appointment involving local anesthesia.
