Potential of nitrous oxide sedation in pedodontics to reduce the need of dental general anesthesia
(2022)
Aim: To investigate the possible reduction of the need for dental general anesthesia (DGA) through nitrous oxide sedation (NOS), when is used in combination with behavior management techniques among patients younger than 12 years of age referred to a specialized pedodontics practice due to the high dental treatment need and poor cooperation level.
Materials and methods: Retrospective analysis was performed of the digital medical records of all children treated under NOS in a specialized pedodontics clinic between 2012 and 2017. The potential reduction of the need for dental general anesthesia was assessed depending on the success rate of NOS on patient-level with relations to multiple related factors such as age, reason of referral and treatment need.
Results: out of 510 patients, 228 meet the inclusion criteria. Nitrous oxide was used in 406 dental treatment sessions on 228 pre-cooperative and/or anxious patients aged 3-12 years (mean 6.4±1.7; 43.4% female). 91.9% of the NOS sessions were successful in achieving the intended dental treatment. Complete oral rehabilitation was possible for 84% of the patients using NOS without the need of DGA. Regarding the age, DGA reduction among pre-school children was lower than in schoolchildren (77.8% and 87.9%, respectively).
Conclusion: A high fraction of anxious or semi-cooperative children with high dental treatment needs can be treated without the use of DGA when a comprehensive concept of caries management is combined with the use of NOS and behavior management techniques. NOS should, therefore, always be considered as an option for dental treatment of semi-cooperative children with high dental treatment needs before making a decision towards DGA.
Objective: To compare the effectiveness and complications of intraligamentary anesthesia
(ILA) with conventional inferior alveolar nerve block (IANB) during injection and dental
treatment of mandibular posterior teeth.
Materials and Methods: In this randomized, prospective clinical trial, 72 patients (39 males, 33
females) patients scheduled for dental treatment of mandibular posterior teeth, were randomly
allocated to ILA group (n=35) received ILA injection or IANB group (n=37) received the
conventional IANB. Our primary outcome was to assess pain and stress (discomfort) during the
injection and dental treatment, using the Numeric Rating Scale (NRS) from 0 to 10 (0 = no
pain, 10= the worst pain imaginable). Whereas; recording 24 hours postoperative complications
were our Secondary outcomes.
Results: Patients in ILA group reported significantly less pain during injection when compared
with IANB group (p=0.03). While pain during dental treatment was similar in both groups
(p=0.2). Patients in both groups also reported similar low values of discomfort during treatment
(p= 0.7). Although no signs of nerve contact or any other postoperative complications were
observed, five patients in IANB group (none in ILA group) reported temporary irritations
Conclusion: This study showed equivalent effectiveness of both intraligamentary anesthesia
and conventional inferior alveolar nerve block, for pain control during routine dental treatment
of mandibular posterior teeth. Nevertheless, ILA showed significantly less pain during
injection. No major postoperative complications in both groups were observed.
Clinical Relevance: ILA could be considered as an effective alternative for routine dental
treatment.
National oral health survey on refugees in Germany 2016/2017: caries and subsequent complications
(2020)
Objectives To assess oral health, caries prevalence, and subsequent complications among recently arrived refugees in Germany and to ompare these findings with the German resident population. Methods This multicenter cross-sectional study recruited 544 refugees aged 3–75+ years; they were examined at ten registration institutions in four federal states in Germany by two calibrated dentists. The refugees were screened for caries (dmft/DMFT) and its complications pufa/PUFA); this data was compared to the resident population via the presentative national oral health surveys). Results The deciduous dentition of the 3-year-old refugees had a mean dmft value of 2.62 ± 3.6 compared with 0.48 dmft in the German resident population, and caries increased to 5.22 ± 3.4 for 6–7-year-olds (Germany: 1.73 dmft). Few refugee children had naturally healthy teeth (7% in 6–7-year-olds, Germany: 56%). In the permanent dentition, the gap in caries prevalence between refugees and the German population decreased with age (35–44-year-olds: 10.55 ± 7.1 DMFT; Germany: 11.2), but refugees exhibited more caries defects (35–44-year-olds DT = 3.13 ± 3.0; Germany: 0.5). German residents had more restorations (35–44-year-olds FT = 4.21 ± 4.6). Regarding complications, the 6–7-year-olds exhibited the highest pufa index (0.86 ± 1.4) which decreased in adolescence (13–17-year-olds, 0.18 ± 0.6) and increased in adults (45–64-year-olds, 0.45 ± 0.8). Conclusion The refugees had high caries experience, often untreated caries teeth and more complications compared with the German resident population, especially in children. Closing this gap by extending preventive systems to the refugees would decrease future treatment needs. Clinical relevance European countries should be prepared for the higher dental treatment needs in recent refugees, especially in
children.
