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.
Cerebral palsy (CP) remains one of the most common debilitating diseases in the world.
Factors such as neuromuscular incoordination, use of soft diet and delayed oral
clearance of food make maintenance of optimum oral hygiene a challenging task in
these children. The compromised oral hygiene in turn make these children highly
vulnerable to dental disease. Maintaining optimal oral/dental health in CP children is of
utmost importance as these children usually suffer from several associated general
health problems in addition to their primary condition. Poor dental health further
compromises their general health. Nevertheless, CP children often suffer from dental
diseases including dental caries more than healthy children. This underscores the need
for improvement in oral health of the CP children. The CP children are dependent on
those around them for their oral hygiene maintenance and dietary intake. CP children
spend most of their time with health care workers in special centers for them or with
their parents/care takers at home. Therefore, the attitude of special health care workers
and parents towards their dental health is of prime importance. The purpose of this
project included to determine the attitude of special health care workers towards their
dental health and oral health comprehension by parents of CP children. In addition, a
study on caries experience of CP children and associated risk factors was also completed.
The final objective was to identify various potential areas of improvement with ultimate
goal of improving dental health of the CP children.
The study involving special health care workers in a Disabled Children’s Center revealed
that oral health knowledge and practices among the workers could generally be labeled
as satisfactory, however some weak areas (such as trend towards symptom-oriented
utilization of oral health care and lack of knowledge about fluoridated water) were
identified. There is a need to enhance the workers’ knowledge in these areas.
The study involving parents of the CP children showed mixed results. Some areas of
strong oral health comprehension (such as importance of good dental health, harmful
effects of sweetened foods), others satisfactory (such as need for routine dental visits,
use of fluoride) and some weak areas (use of flavored fizzy drinks, bottled/canned juices
and sweetened/flavored milks, seeking early treatment) were identified among parents
of CP children. The results strongly indicated a need for enhanced efforts towards
improvement of oral health comprehension in the parents of the CP children.
The study about caries experience and risk factors in CP children has provided useful
information in an area where literature has been scarce. Almost all the studied children
had clinical dental caries, and most of the caries were untreated. Very few children in
the present study had optimal oral hygiene. This study confirmed the strong correlation
between high dental caries experience and poor oral hygiene. Routine dental check-up
visits and topical fluoride application clearly resulted in lower caries experience. Bottled
juices and crispy potato chips were the two predictors for high caries experience.
As stated before, the goal of the project was to identify various potential areas of
improvement in oral health attitude of special health care workers, oral health
comprehension of the parents of CP children and risk factors for dental caries in CP
children. It is contemplated that by addressing the identified weak areas, an
improvement in dental health and care of the CP children is expected. It is also expected
that the collected information will help in improvement of clinical preventive as well as
restorative services for the CP children. CP children and their parents lead a challenging
life. This project was an effort to assist these children and their parents/care takers with
ultimate goal of improving their oral health and in turn their overall quality of life.
Despite a plethora of therapeutic approaches, the injection of local anaesthetics itself remains one of the most painful and dreadful procedures among children. Stimulation of acupoint LI4 is associated with analgesic effects in dentistry. Goal of the study To investigate whether stimulation of LI4, added to standard therapy (ST), reduces pain and distress during injection of local anaesthetic (LA) in comparison with ST alone. Materials and Methods Children, scheduled for dental treatment in local anaesthesia on 2 separate days were enrolled in this trial, approved by local ethics commission. On one day each child received bilateral acupuncture of LI4 point, using indwelling fixed “New Pyonex” needles (0.2 x 1.5 mm; Seirin, Japan). The parents of the children were asked to stimulate the needles by massage. Standardized injection of LA was performed 5 min following acupuncture. The needles were withdrawn at the end of dental treatment. On the other day of treatment children received LA injection without acupuncture. The order of treatment days (acupuncture first or vice versa) was randomised. Primary endpoint was the pain intensity during LA injection reported by children on Visual Rating Scale from 0=no pain to 10=maximal pain imaginable (VRS-11). Secondary endpoints were parent- and dentist-assessed pain intensity (measured on Numeric Rating Scale 1-10), patients’ heart rate before and during dental treatment and satisfaction with received therapy (measured on Numerical Rating Scale 1-5.) Side effects of LI4 stimulation were also recorded. Results and Discussion The data of 49 children (22 females; age 10 ± 4 yrs; mean ± SD), who completed both visits, were analysed. Children reported less pain with than without acupuncture: 2.2 ± 2.5 vs. 3.9 ± 2.7; mean ± SD, p<0.001. Heart rate decreased after LI4 stimulation compared to ST alone throughout the dental treatment (p<0.05). LI4 stimulation was safe and raised better satisfaction with the treatment among children and parents, than ST alone (p<0.05). Other secondary endpoints were comparable between both sessions. Conclusion Stimulation of acupuncture point LI4 reduces pain and autonomous stress during injection of local anaesthetics in paediatric dentistry.
The aims of this study were to 1) determine if continuous eruption occurs in the maxillary teeth, 2) assess the magnitude of the continuous eruption, and 3) evaluate the effects of continuous eruption on the different periodontal parameters by using data from the population-based cohort of the Study of Health in Pomerania (SHIP). The jaw casts of 140 participants from the baseline (SHIP-0) and 16-y follow-up (SHIP-3) were digitized as 3-dimensional models. Robust reference points were set to match the tooth eruption stage at SHIP-0 and SHIP-3. Reference points were set on the occlusal surface of the contralateral premolar and molar teeth, the palatal fossa of an incisor, and the rugae of the hard palate. Reference points were combined to represent 3 virtual occlusal planes. Continuous eruption was measured as the mean height difference between the 3 planes and rugae fix points at SHIP-0 and SHIP-3. Probing depth, clinical attachment levels, gingiva above the cementoenamel junction (gingival height), and number of missing teeth were clinically assessed in the maxilla. Changes in periodontal variables were regressed onto changes in continuous eruption after adjustment for age, sex, number of filled teeth, and education or tooth wear. Continuous tooth eruption >1 mm over the 16 y was found in 4 of 140 adults and averaged to 0.33 mm, equaling 0.021 mm/y. In the total sample, an increase in continuous eruption was significantly associated with decreases in mean gingival height (B = −0.34; 95% CI, −0.65 to −0.03). In a subsample of participants without tooth loss, continuous eruption was negatively associated with PD. This study confirmed that continuous eruption is clearly detectable and may contribute to lower gingival heights in the maxilla.
Background: Despite of the remarkable caries reduction in permanent dentition, caries levels of primary teeth has stagnated in Germany. Early Childhood Caries (ECC) or also known as baby bottle tooth decay is the most vulnerable form of caries in young children, but minimal data and information from different German states are available to determine the appropriate preventive programs. Aim: The purpose of the current study is to find the prevalence of ECC among young children in the state of Mecklenburg-Vorpommern (North-East Germany) and to optimize an intervention on ECC prevention in a community setting. In addition to education, fluoride varnish is evaluated on young children with active ECC. Design: In this cross-sectional study, a total of 4283 children living in the state of Mecklenburg-Vorpommern were examined. Four age groups - with an accuracy of one day - were formed as follows: less than one year (n=8), one year (n=293), two years (n=1618) and three years (n=1888). The examination was carried out by community dental service’s examiners whom are calibrated to ECC diagnostic criteria of Robke and Buitkamp (2002), and dmf-t values for caries diagnosis. These data are compared by those of children (n=5355) of same age group for the year 2011-2012. In addition, a structured questionnaire on the starting preventive programme on ECC was filled out by the community dentists and for the city of Greifswald, fluoride varnish (Duraphat®, 5% NaF = 2.26%F, Colgate-Palmolive, Germany) was applied for 32 children previously diagnosed with active ECC (ECC1: n=15, ECC2: n=17). Lesions are identified as active or non active according to texture and luminosity, and oral hygiene index (OHI-S) is measured and re-evaluated at three months follow up. Results: The percentage of children under three years old in 2012-2013 with ECC was comparatively low (4%) which possibly reflects the very young age of the children and a restriction for ECC on the upper incisors. The overall caries prevalence in Mecklenburg-Vorpommern varied from 9% to 15%. Most cavitated lesions are untreated. These results are comparable with the results from other German counties. The interventions of the ECC programme vary considerably among the different counties. There was no significant difference in the oral hygiene index (OHI-S) prior and post fluoride varnish application (p-value = 0.25). The use of fluoride varnish resulted in an 81%, statistically significant decrease of active ECC lesions in Greifswald (p < 0.001). Conclusion: The prevalence of caries among young children was considerable in Mecklenburg-Vorpommern. A preventive intervention in nurseries and fluoride varnish applications for active ECC lesions seems to be a feasible approach in controlling caries in early childhood. However, further quality management and standardization of the program should be reinforced.
Background: Referral to specialized pediatric treatment seems to rise in Germany, especially for children under 5 years of age and mostly due to behaviour management problems, rampant caries and the need for comprehensive dental treatments. There are indications that more dental treatments under general anesthesia were needed in last decade, but there are very few studies on this topic in Germany. Aim: The objectives of this research were to investigate the characteristics and dental features of referred children to Greifswald university dental clinic in 2008 and 2011 as well as to assess dental treatment and characteristics of the children who underwent general anesthesia in 2011 at Greifswald University Clinic in comparison with three specialized pediatric private practices in Germany. Materials and methods: This retrospective analytical comparative study examined the records of all children younger than 18 years of age, whose were referred to the university dental clinic in Greifswald between 2008 and 2011. In addition, all cases that underwent general anesthesia at the university dental clinic and three other private practices in 2011 were analyzed anonymously. All data including age, gender, dental status and caries levels (dmft/DMFT), as well as diagnosis, referral/GA reasons and the dental treatments were collected and then analyzed using the Statistical Package for the Social Sciences program (SPSS, Ver. 16 for Windows). Descriptive analysis was performed, along with univariate analysis of variance (ANOVA) and Chi square tests. Differences between groups were tested through Mann-Whitney U test and Student’s t-test as appropriate. Results: The final study sample for children and adolescents referred to the university consisted of 389 under 18 years old (205 males and 184 females) with a mean age of 8.75 years in 2008 and 7.38 years in 2011. In addition, 297 children (160 males and 137 females) with a mean age of 4.77 years had been treated under general anesthesia in the three specialized private practices (n= 219, age: 4.81±2.06 years) and in the university (n=78, age: 4.65±2.59 years). More patients of age group 1 (5 yrs or younger), as well as, patients residing within a distance of 31-40 km away from the clinic were referred in 2011 (47.2% and 35.9% resp.) in comparison with 2008 (37.1% and 22.7% resp.) Panoramic and intraoral dental x-rays (46.7%, 11.8% resp.) have been widely carried out in 2011 compared to 2008 (29.9%, 6.5% resp. P = 0.002). Statistical analyses have shown that, younger children with higher values of dental caries indices (dmft, DMFT) were referred in 2011 (5.4 and 2.15 resp.) than in 2008 (5.16 and 1.57 resp.) with increasing demand for comprehensive dental treatment under GA. Whereas, more patients were diagnosed to have rampant caries (42.1%) in 2011 followed by orthodontic/oral surgery problems (16.9%) in comparison with 2008 (29.3%, 10.1% resp. P < 0.001). Non-invasive treatment was much more delivered (63%) in first dental visit for referred patients in 2011 followed by dental consultation (23.6%) compared to 2008 (53.6% and 21.3% resp.). While, on the other hand, considerably more fillings were supplied in 2008 (11.5%) compared to 2011 (2.6%). Further dental treatment pattern revealed more treatment under GA (27%) and a slightly more extractions (16.1%) were done in 2011 compared to 2008 (20.9%, 15.5% resp.). On the contrary, less fillings and preventive procedures were performed in 2011 (26.3% and 4.4% resp.) in comparison with 2008. Sixty-one percent of children were referred back to their family dentists in 2011 which was more than it in 2008. Indeed, about a half of children aged 5 years or younger preferred to stay at the University Clinics in 2011, while, the vast majority of children older than 12 years continued their dental care outside the University Clinics. About eighty percent and seventy percent of children underwent GA at both the university clinics and private practices respectively were under five years old. In total 7.1% mental disabilities and 2.4% preterm birth were detected in children treated under GA, as well as, dental caries were mostly diagnosed (37%) among them followed by irreversible pulpitis (21.5%) and Early Childhood Caries (ECC) (18.5%), where only 4.38% of all examined children had no carious lesions. More panoramic radiographs (41%) and less dental films (26.9%) were conducted at the university clinics as in the private practices (15.1% and 52.1% respectively) with a significant reduction in using x-rays at the university (69.2%) compared to private practices (94.1%). Dental extractions were often performed at university clinic (40.2%, 3.14±2.4) followed by fillings (33.9%, 2.65±2.7), while, more restorations and less extractions were supplied at private practices (47.8%, 5.47±3.1 and 16.3%, 1.86±2 resp.). Both of long (106-120 Min) and short (0-15 Min) treatment’s durations were needed in the university clinics to carried out the adequate dental therapy under GA, while, most of the GAs at private practices have lasted between 45 and 90 minutes. Conclusion: There is a growing definite need for specialized pediatric dentistry in Germany, especially for children under 5 years of age being referred with rampant caries and behaviour management problems to specialized pediatric dentistry. This results in a high number of extensive treatment performed under GA. In contrast to other countries, this seems to be a singular event for most children in Germany indicating a solid treatment under GA and possibly also improvements in the caries activity of the affected children afterwards. The range of dental treatment and its outcome at Greifswald University and in the examined three specialized private practices is very similar reflecting in both the profile of the children a valid indication for GA and the subsequent treatment up to date approaches in pediatric dentistry. Thus, the very professional treatment and effective secondary preventive strategies achieve better oral health and reestablished quality of life for these children, but a primary preventive approach would be preferable decreasing the number of children in need of dental treatment under general anaesthesia.
40-Year Longitudinal Caries Development in German Adolescents in the Light of New Caries Measures
(2019)
This study assessed the 40-year longitudinal caries development in German adolescents in the light of the sixth National Oral Health Survey in Children (NOHSC, 2016) employing initial DMFT (IDMFT), Significant Caries Index (SiC) and Specific Affected Caries Index (SaC). On the basis of the current NOHSC (randomized cluster selection using school list or regional community school surveys, 55,956 12-year-old sixth-graders examined by 482 calibrated community/study dentists) DMFT, SiC, a novel IDMFT including initial lesions (IT) and the recently introduced SaC were calculated and also recalculated for national and international surveys from the last 4 decades. In 2016, 78.8% of children were caries-free (DMFT = 0), 65.5% including IT lesions. The mean DMFT was 0.44 (single components: DT = 0.14, MT = 0.02, FT = 0.29, IT = 0.52) showing a clear association with the school type as marker for the socio-economic status. The mean number of affected teeth in children with DMFT >0 was 2.07 (SaC) in comparison to almost 9 teeth in the 1970s. The current care index on the tooth level was 66.3%, leaving only 7.7% of children with restorative treatment needs. Longitudinally, a continuous caries decline of more than 80%, including the risk groups (SiC/SaC), to an internationally extremely low level was observed. In conclusion, the National Oral Health Surveys reveal a continuous caries decline to a very low caries level in 12-year-old 6th-graders in Germany even if IT lesions are included (IDMFT). In spite of proportional reductions in the risk groups (SiC/SaC), the polarized caries distribution according to socio-economic parameters reveals the need for targeted preventive programmes.
This paper reviews the first part of the outcomes of the ORCA Saturday Afternoon Symposium 2014 dealing with ‘caries epidemiology and community dentistry: chances for future improvements in caries risk groups'. After the caries decline in many countries, there are remaining pockets of higher caries levels, mostly in the primary dentition and/or linked to a low socio-economic status (SES). The review into the evidence of caries-preventive measures clearly points to the use of fluorides, especially toothbrushing with fluoridated toothpaste and collective measures such as water fluoridation. In contrast to several unsuccessful high-risk approaches, community and public health programmes seem to be able to ensure a population-wide access and compliance in risk groups. Their simple and evidence-based measures mostly combine regular plaque removal and fluoride applications via toothbrushing, at least for children and adolescents. For the future, the common risk factor approach which addresses associations between oral health, social deprivation, diet, hygiene, smoking, alcohol use and stress should lead to combined efforts with other community health and education specialists. Further engagement with public policy, community leaders and administration is needed in order to strengthen healthy choices and behaviour, e.g. in ‘healthy' schools and kindergartens. It seems advisable that these population programmes also aim at improving upstream factors.
Background: Early childhood caries remains an unsolved problem in children under three worldwide. Midwives are important health care persons around birth and can shape behavior. They possibly can play a positive role in preventing early childhood caries in young children. Objective: to assess how involved midwives are in early childhood caries prevention, what preventive measures they recommend and what knowledge they have about early childhood caries, as well as to study the potential differences between the various federal states or due to their work experience. Materials and Methods: An online survey targeted midwives in Germany regarding their knowledge about early childhood caries as well as the preventive measures they recommended. Participants were members of the German Association of Midwives (DHV). The survey invitation was published with the monthly newsletter and in the association journal of the DHV. Data was collected anonymously. Results: 191 midwives nationwide responded to the questionnaire. Most midwives were aware about ECC prevalence, consequences, causes and the teeth mainly affected. Midwives gave excellent recommendations regarding diet, oral hygiene and avoiding prolonged bottle feeding. However, only 40.8% of midwives recommended the first dental visit with the eruption of the first tooth. 71.7% recommended a fluoride tooth paste with the eruption of the first tooth. The rest advised a later use or non-fluoridated toothpaste. Regional differences were minimal. Conclusion: Midwives have good oral health knowledge, but there is some variability in recommendations on the first dental visit and the use of fluoride toothpaste which reflects an inconsistency of professional recommendations delivered by different health care institutions in Germany.
The aim of this study has twofold. First, to investigate characteristics of paediatric patients seeking emergency dental care and the according treatment in a specialised dental service. The second aim, to propose a data-based guidance for management of dental emergency in children including pain management without traumatizing the child and with a clear differentiation of dental emergency patients.
Records of the demographic and clinical characteristics of 332 children (mean age 8.2 ±4.2 years) who attended the Department of Preventive and Paediatric Dentistry at the University of Greifswald in 2018 without an appointment seeking emergency dental care were collected. Statistical analysis was carried out using descriptive statistics and Chi-square tests. Based on the data a proposal for management of emergency/pain patients was performed.
Pain patients were high caries risk children (mean: 4.59 ±3.65 dmft, 1.65 ±2.73 DMFT). The main clinical diagnoses of pain patients in all different age groups were dental caries and caries-related complications such as reversible and irreversible pulpitis or periapical periodontitis (63.6%), while dental trauma contributed (8.4%). In general, the most frequent treatment was extraction (41.0%), most of these extractions needed to be rendered under either nitrous oxide sedation or general anaesthesia (57.3%).
This study has shown a clear association between the dental emergency management plan (delay of the dental treatment) and other factors such as, the required treatment (invasive or not invasive) P < 0.05, the need of sedation P < 0.05 and child’s previous dental experience (first visit to the dental clinic) P < 0.001. Most of the extraction procedures were not rendered immediately in the emergency/pain visit, rather they were delayed to be performed in the next treatment session (70%), with the majority of these procedures planned to be rendered under sedation. On the other hand, most of the restorations (65.5%) were performed in the emergency/pain visit, with need of sedation for only (8.3%) of these procedures. In addition, the majority of treatments of children who were visiting the dental clinic for the first time were postponed (71.6%; n=63). The correlation analysis shows a higher tendency to postpone the treatment when the required treatment is invasive, need to be rendered under sedation or when
it was the child’s first visit to the dental clinic. These findings indicate the strong impact of child’s cooperation on the emergency management plan.
Based on these data the guidance for management of peadiatric dental emergency patients was developed including pain management without causing negative affect of the child’s future cooperation
