Purpose: To collect and evaluate the available evidence on existing tools used in research and clinical practice to assess and analyse the diet of children and adolescents for its cariogenicity. Materials and Methods: Multiple databases were searched up to October 2022, with no date, publication, or language restrictions, followed by a manual search. Study screening, data extraction, and risk of bias assessment were performed in duplicate. Dietary assessment tools and dental clinical parameters tested were retrieved for qualitative assessment and synthesis. Results: Of the 2896 papers identified, 9 cohort and 23 cross-sectional studies fulfilled the inclusion criteria. To assess dietary data, 13 studies used a 24-h recall, 11 used a food diary, and 7 used a food frequency questionnaire. For analysis, five studies reported using the Healthy Eating Index, ten used a score based on consumption of sugars, and the remaining analysed cariogenic diet based on the weight and frequency of sugars consumed, or the daily caloric intake from free sugars. Risk of bias assessment suggested that 65.7% of the studies were of moderate and 31.5% of high quality. Conclusion: Inconsistency exists regarding methods used for the assessment and analysis of dietary cariogenicity. Although every dietary assessment tool has different strengths and limitations, the 24-h recall was the most commonly used method for the assessment of dietary cariogenicity and the most consistent in detecting a positive relationship between sugary diet and carious lesions. A standardised method for cariogenic analysis of dietary data needs to be determined. Keywords: cariogenic diet, dietary assessment tools, food diary, 24-h recall

Purpose: With success rates comparable to that of root canal treatment, vital pulp therapy (VPT) has gained clinical interest and has been used in the management of young permanent teeth with inflamed pulps. The aim of the present study was to retrospectively evaluate the radiographic success of VPT in young first permanent molars 24 months post-treatment and correlate findings with tooth and treatment-related characteristics. Materials and Methods: Dental records of all patients with first permanent molars which received VPT in the Department of Paediatric Dentistry (National and Kapodistrian University of Athens) were retrieved. Demographic characteristics and data regarding the treatment performed were recorded. Patients’ radiographs were evaluated at 6, 12 and 24 months post-treatment by two qualified paediatric dentists blinded regarding the treatment performed. Radiographic success, reasons for failure and continuation of root development were evaluated. Differences were tested using the Χ2 and Student’s t-test, and possible correlations were determined by calculating the odds ratio. Results: Overall radiographic success rate at 24 months was 77%, ranging between 50% for direct pulp capping and 92% for full pulpotomy. Differences were not statistically significant. Continuation of root development was recorded in almost 1/3 of the teeth and completion in almost 1/5. No statistically significant association was recorded between the outcome and any tooth and treatment-related variables. Conclusion: VPT seems to be a reliable option in the long term for the treatment of deep carious lesions in young permanent molars.

Objective: To investigate the effect of a 5% sodium fluoride varnish with functionalized tri-calcium phosphate (fTCP) on post-orthodontic white spot lesions. A secondary aim was to study if the patients and their clinicians perceived clinical improvements. Method and materials: Fifty-nine patients with at least two visible WSLs on their maxillary incisors, canines, or first premolars present at the debonding of fixed appliances (baseline) were enrolled and assigned to a Varnish group (Clinpro White Varnish, 3M Espe) receiving topical applications at baseline and after 8 weeks, or a Control group treated with a fluoride-free mock product. The primary endpoint was white spot lesion appearance after 16 weeks, assessed from photographs using the modified ICDAS white spot lesion score (0 to 3). The patients and the dental examiners rated the white spot lesions subjectively with aid of a visual analog scale. Results: Fifty-seven patients completed the study. After 16 weeks, 62% of the white spot lesions in the Varnish group were completely reversed (score 0) compared to 39% in the Control group. The treatment effect was statistically significant (OR 0.22; 95% CI 0.08 to 0.59, P = .003) after adjusting for baseline oral hygiene index and type of tooth. A significant correlation (P < .05) was observed between patients' and orthodontists' perception of the lesions. Conclusion: The 5% sodium fluoride varnish with fTCP appeared clinically effective in reversing post-orthodontic white spot lesions 16 weeks after debonding. The patients and the clinicians agreed on the obtained esthetic improvements. Keywords: adolescents, orthodontics, remineralization, secondary prevention, white spot lesion

Purpose: White spot lesions (WSL) are common side-effects of orthodontic treatment with fixed multi-bracketed appliances. The aim of this review was to find all available literature and critically assess the evidence for the efficacy of bleaching as a method to treat or alleviate post-orthodontic WSLs in permanent teeth. Materials and Methods: Electronic databases were screened for relevant literature with the aid of predetermined search strategies. All types of studies, including randomised or nonrandomised controlled trials (RCTs or CCTs), prospective and retrospective studies, as well as in vitro studies were considered eligible for inclusion. The reference lists of all included articles were hand searched for additional studies. Two authors independently performed study selection, data extraction, and risk of bias assessment. Results: One RCT and 8 in vitro studies met the inclusion criteria. Seven studies were classified as having a high risk of bias while 2 in vitro studies were graded as having a moderate risk of bias. The results showed that bleaching of WSL can diminish colour disparities between carious and non-affected areas, but the certainty of the evidence was very low. The high degree of methodological heterogeneity precluded a valid interpretation of the results through pooled estimates. Conclusions: The findings from the present systematic review could not support or refute bleaching as an effective method for management of post-orthodontic WSLs. Because most of the studies in this field are in vitro and solid scientific evidence of low risk of bias is scare, further prospective in vivo studies are necessary.

Das dem Beitrag zugrunde liegende Positionspapier der European Academy of Paediatric Dentistry (EAPD) soll Zahnärzten bei der Entscheidung helfen, wann und wie sie die Lokalanästhesie bei Kindern, Jugendlichen und jungen Patienten mit Grunderkrankungen im Rahmen der zahnmedizinischen Versorgung einsetzen können. Die wichtigste Aussage aus den Empfehlungen ist, dass die Lokalanästhesie bei sachgemäßer Verabreichung, d. h. korrekter Wahl und Dosierung des lokalanästhetischen Wirkstoffs bzw. Vasokonstriktorzusatzes, sowie bei indikationsgerechter Applikationstechnik zum einen eine klinisch wirksame Schmerzkontrolle bei der Behandlung von Kindern ermöglicht und zum anderen ein sehr geringes Risiko für das Auftreten von lokalen oder systemischen Nebenwirkungen in sich birgt. Daneben wurden zahlreiche Wissenslücken identifiziert, die auf einen niedrigen Evidenzgrad und damit zukünftigen Forschungsbedarf hinweisen.
