National oral health survey on refugees in Germany 2016/2017: caries and subsequent complications.

OBJECTIVES: To assess oral health, caries prevalence, and subsequent complications among recently arrived refugees in Germany and to compare 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 representative 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.

How to intervene in the caries process: proximal caries in adolescents and adults-a systematic review and meta-analysis.

OBJECTIVES: For an ORCA/EFCD consensus, this systematic review assessed the question "How to intervene in the caries process in proximal caries in adolescents and adults". MATERIAL AND METHODS: Separating between the management of initial and cavitated proximal caries lesions, Medline via PubMed was searched regarding non-operative/non-invasive, minimally/micro-invasive and restorative treatment. First priority was systematic reviews or randomized controlled trials (RCTs), otherwise cohort studies. After extraction of data, the potential risk of bias was estimated depending on the study type, and the emerging evidence for conclusions was graded. RESULTS: Regarding non-invasive/non-operative care (NOC), no systematic reviews or RCTs were found. In cohort studies (n = 12) with a low level of evidence, NOC like biofilm management and fluoride was associated with a low proportion and slow speed of progression of initial proximal lesions. Minimally/micro-invasive (MI) treatments such as proximal sealants or resin infiltration (four systematic reviews/meta-analyses) were effective compared with a non-invasive/placebo control at a moderate level of evidence. Data on restorative treatment came with low evidence (5 systematic reviews, 13 RCTs); with the limitation of no direct comparative studies, sample size-weighted mean annual failure rates of class II restorations varied between 1.2 (bulk-fill composite) and 3.8% (ceramic). Based on one RCT, class II composite restorations may show a higher risk of failure compared with amalgam. CONCLUSIONS: Proximal caries lesions can be managed successfully with non-operative, micro-invasive and restorative treatment according to lesion stage and caries activity. CLINICAL RELEVANCE: Proximal caries treatment options like non-operative, micro-invasive and restorative care should be considered individually.

School-based oral health education increases caries inequalities.

OBJECTIVE: To evaluate the effect of one and half years of an oral health promotion program in primary schools. DESIGN: A cluster-randomized controlled trial. PARTICIPANTS: 740 students aged 9-12 years (48% female) recruited from the fifth grade of 18 different primary schools in West Pomerania, Germany. METHODS: General and oral health education was provided to the teachers in the intervention schools, which they conveyed to their students. No additional measures were conducted in the control schools. Medical and dental school examinations, as well as questionnaires for the students and their parents were conducted at baseline and follow-up. Data were analysed using Poisson regression models. RESULTS: A significant incident rate ratio between caries increment was found, with a 35% higher risk in the control group. However, parents' socioeconomic characteristics modified the effect of the program on their children, as high socio-economic status in the intervention group was associated with 94% reduction in the incidence risk ratio (p ⟨ 0.001). CONCLUSIONS: The program was effective in improving dental health among students with higher socio-economic status. No preventive effect could be found in low socio-economic status groups.

Treatment of Carious Lesions Using Self-Assembling Peptides.

Modern approaches in caries treatment involve lesion management without tissue removal. Regenerative medicine focuses on replacing damaged tissues with biologically similar tissues. This article discusses the scientific evidence and clinical results for self-assembling peptides in modern caries management. The biomimetic remineralization promoted by self-assembling peptide P11-4 has been proven in vitro as an effective therapy for initial caries. P11-4 was rationally designed to promote formation of hydroxyapatite on its surface. The formulation was optimized to ensure the ability of monomeric P11-4 to penetrate past the subsurface lesions and assembly into a biomatrix within. Furthermore, P11-4 has shown that it assembles into fibers within carious lesions, and promotes the remineralization thereof. In a recent clinical study, the safety and efficacy of P11-4 in treatment of initial caries were evaluated. The additional effect of the application of P11-4 (Curodont Repair) was compared to the application of fluoride varnish (Duraphat) alone in active occlusal initial caries lesions on erupting permanent molars. In the 3- and 6-month recalls, the test group showed, both in the laser fluorescence readings and in the clinical assessment of the caries stage and activity, significantly superior lesion regression compared to the control group. No adverse events, medical complications, or allergic reactions related to the treatments were reported. Clinical applicability of treatment was regarded as satisfactory. Patients were happy to receive noninvasive caries treatments. In conclusion, biomimetic mineralization facilitated by P11-4 in combination with fluoride may present a simple, safe, and effective noninvasive treatment for early carious lesions.

Managing Carious Lesions: Consensus Recommendations on Terminology.

Variation in the terminology used to describe clinical management of carious lesions has contributed to a lack of clarity in the scientific literature and beyond. In this article, the International Caries Consensus Collaboration presents 1) issues around terminology, a scoping review of current words used in the literature for caries removal techniques, and 2) agreed terms and definitions, explaining how these were decided.Dental cariesis the name of the disease, and thecarious lesionis the consequence and manifestation of the disease-the signs or symptoms of the disease. The termdental caries managementshould be limited to situations involving control of the disease through preventive and noninvasive means at a patient level, whereascarious lesion managementcontrols the disease symptoms at the tooth level. While it is not possible to directly relate the visual appearance of carious lesions' clinical manifestations to the histopathology, we have based the terminology around the clinical consequences of disease (soft, leathery, firm, and hard dentine). Approaches to carious tissue removal are defined: 1)selective removal of carious tissue-includingselective removal to soft dentineandselective removal to firm dentine; 2)stepwise removal-including stage 1,selective removal to soft dentine, and stage 2,selective removal to firm dentine6 to 12 mo later; and 3)nonselective removal to hard dentine-formerly known ascomplete caries removal(technique no longer recommended). Adoption of these terms, around managing dental caries and its sequelae, will facilitate improved understanding and communication among researchers and within dental educators and the wider clinical dentistry community.

Managing Carious Lesions: Consensus Recommendations on Carious Tissue Removal.

The International Caries Consensus Collaboration undertook a consensus process and here presents clinical recommendations for carious tissue removal and managing cavitated carious lesions, including restoration, based on texture of demineralized dentine. Dentists should manage the disease dental caries and control activity of existing cavitated lesions to preserve hard tissues and retain teeth long-term. Entering the restorative cycle should be avoided as far as possible. Controlling the disease in cavitated carious lesions should be attempted using methods which are aimed at biofilm removal or control first. Only when cavitated carious lesions either are noncleansable or can no longer be sealed are restorative interventions indicated. When a restoration is indicated, the priorities are as follows: preserving healthy and remineralizable tissue, achieving a restorative seal, maintaining pulpal health, and maximizing restoration success. Carious tissue is removed purely to create conditions for long-lasting restorations. Bacterially contaminated or demineralized tissues close to the pulp do not need to be removed. In deeper lesions in teeth with sensible (vital) pulps, preserving pulpal health should be prioritized, while in shallow or moderately deep lesions, restoration longevity becomes more important. For teeth with shallow or moderately deep cavitated lesions, carious tissue removal is performed according toselective removal to firm dentine.In deep cavitated lesions in primary or permanent teeth,selective removal to soft dentineshould be performed, although in permanent teeth,stepwise removalis an option. The evidence and, therefore, these recommendations support less invasive carious lesion management, delaying entry to, and slowing down, the restorative cycle by preserving tooth tissue and retaining teeth long-term.

[GeKo KidS--Health Literacy in School Children]. / GeKo KidS--Gesundheitskompetenz bei Kindern in der Schule.

The main goal of this study was the evaluation of an intervention programme for the promotion of health literacy in school-aged children (grade 5-6). The project and the programme were highly accepted, the extension of the annual dental health examination was suitable to collect data within evaluation projects in schools. In spite of positive outcomes, a longer supervision phase would be necessary in order to optimise and to implement other programme components fully.

Clinical safety, quality and effect of resin infiltration for proximal caries.

AIM: Resin infiltration of proximal lesions is a new approach to stop caries progression. The aim of this clinical trial was to assess its safety and quality, as well as the therapeutic effect. MATERIALS AND METHODS: In 47 children, adolescents and young adults, ten dentists applied the infiltration material ICON (DMG, Germany) on initial proximal lesions according to the manufacturer's instruction. One lesion with radiographic extension into enamel or the outer third of dentin per participant was allocated for the treatment. The clinical safety and quality of resin infiltration were assessed 1 week, 6 months and 12 months after the treatment and the evaluation of the therapeutic effect was analysed by pair-wise radiographs. RESULTS: The clinical safety and quality of the infiltration were assessed in 45 individuals after 12 months. The test surfaces showed no relevant changes in clinical status, plaque accumulation or gingival status (p > 0.05). A high quality of infiltration was found for the marginal adaptation. In contrast to the improvement of colour at the one-week recall (p = 0.005), the infiltrated surfaces showed a statistically significant increase in the discoloration within the following year (p = 0.014). Out of the 43 lesions which could be assessed radiographically, only two lesions showed progression to a different score (4.7%). CONCLUSION: Resin infiltration can be considered a safe and effective treatment to reduce progression of initial proximal caries.

The impact of bias of underlying literature in guidelines on its recommendations: assessment of the German fluoride guideline.

PURPOSE: The significance of the underlying literature in clinical guidelines can be weakened by the risk of bias, which could negatively affect the recommendations. Especially in controversial matters, such as fluoride use for caries prevention in children, biased results may be not reliable and lead to incorrect conclusions. This study was performed to detect bias in underlying literature of the German guideline for caries prevention using fluoride in children, where no consensus was reached between paediatricians and paediatric dentists. METHODS: Three tools used for risk of bias assessments of different study designs were RoB 2 for RCTs, ROBINS-I for non-randomized studies, and ROBIS for systematic reviews. For each study cited in the guideline two independent risk of bias assessments were performed. Disagreements were resolved by consensus. RESULTS: Out of 58 papers, 48.3% (n = 28) showed high risk of bias, with the majority in sections regarding fluoride tablets, fluoridated toothpaste, and paediatricians' recommendations. 9 out of 20 recommendations and statements were based on studies with high risk of bias, all of which were in these three controversial sections. 13 out of 29 RCTs showed high risk of bias (44.8%), as all 13 non-randomized trials did, while only 2 of 16 (12.5%) systematic reviews had high risk of bias. CONCLUSION: Considering risk of bias of cited studies in clinical guidelines may result in substantial changes in its recommendations and aid in reaching consensus. Efforts should be made to assess risk of bias of underlying literature in future clinical guidelines.

Predicting caries by measuring its activity using quantitative light-induced fluorescence in vivo: a 2-year caries increment analysis.

The aim of this study was to analyse the predictive power of several clinical baseline parameters and the de-/remineralisation properties of in vivo etched sites measured with quantitative light-induced fluorescence (QLF) for subsequent 2-year caries increment. At baseline, in 44 children (8.23 ± 1.5 years) two areas (diameter 2 mm) of the buccal surface of a primary posterior tooth were etched with 36% phosphoric acid gel for 1 and 4 min, respectively. The etched sites were analysed immediately after etching (ΔQ1) and 24 h (ΔQ2) later by QLF. Additionally, caries status (deft/DMFT and initial caries), approximal plaque, bleeding on probing, and the patient's current use of fluorides were recorded. In the 2-year follow-up, 29 children were re-assessed. After clinical examination, the caries increment was calculated (ΔDMFT) and correlated with the baseline clinical variables and the QLF readings. Results showed a significant positive correlation between ΔQ(1 min) and the ΔDMFT (r = 0.44, p = 0.02). The ΔDMFT was significantly correlated with the baseline deft (r = 0.56, p = 0.002), cavitated active caries lesions (r = 0.52, p = 0.003), and filled teeth (r = 0.53, p = 0.003). In a regression analysis the use of fluoridated salt (SC = -0.10) and fluoride gel (SC = -0.14) were negatively associated with ΔDMFT. In conclusion, these findings suggest that the demineralisation properties of the etched sites and the outcome of the 24-hour measurements with QLF are significantly associated with caries increment. Previous caries experience strongly correlated with caries increment in this group of children.

Impact of operators' experience and patients' age on the success of nitrous oxide sedation for dental treatment in children.

AIM: To evaluate the success rates and potential influencing factors of nitrous oxide sedation for dental treatment in a specialised paediatric dental service. MATERIALS: Medical records of all children treated under nitrous oxide sedation in a specialised pedodontics clinic between 2012 and 2017 were analysed retrospectively for parameters such as age of the patient, experience and change of operating dentists, treatment procedure and success or failure regarding the sedation and treatment. CONCLUSION: Given the high overall success rate of over 90%, nitrous oxide sedation can be a highly effective treatment option for performing dental treatment in pre-cooperative and/or anxious children and adolescents. With age of the children and experience of the dentist, success rates increased.

European core curriculum in cariology for undergraduate dental students.

As dental caries prevalence is still high in many populations and groups of both children and adults worldwide, and as caries continues to be responsible for significant health, social and economic impacts, there is an urgent need for dental students to receive a systematic education in cariology based upon current best evidence. Although European curriculum guidelines for undergraduate students have been prepared in other dental fields over the last decade, none exist for cariology. Thus the European Organisation for Caries Research (ORCA) formed a task force to work with the Association of Dental Education in Europe (ADEE) on a European Core Curriculum in Cariology. In 2010, a workshop to develop such a curriculum was organised in Berlin, Germany, with 75 participants from 24 European and 3 North-South American countries. The Curriculum was debated by five pre-identified working groups: I The Knowledge Base; II Risk Assessment, Diagnosis and Synthesis; III Decision-making and Preventive Non-surgical Therapy; IV Decision-making and Surgical Therapy; and V Evidence-based Cariology in Clinical and Public Health Practice and then finalised jointly by the group chairs. According to this Curriculum, on graduation, a dentist must be competent at applying knowledge and understanding of the biological, medical, basic and applied clinical sciences in order to recognise caries and make decisions about its prevention and management in individuals and populations. This document, which presents several major and numerous supporting competences, does not confine itself to dental caries alone, but refers also to dental erosion/non-erosive wear and other dental hard tissue disorders.

Dental trauma characteristics in the primary dentition in Greifswald, Germany: a comparison before and after German unification.

BACKGROUND: The data on the distribution and pattern of dental trauma in the primary dentition are very rare. AIM: To investigate primary dental trauma patterns in relation to gender, age, time and cause for a recent paediatric cohort and to compare this with a historic one before German unification. METHODS: This retrospective study compared the patterns of dental trauma injuries at the trauma centre at Greifswald University/Germany for a recent paediatric cohort (2014-16, 103 children) with a historic one (1974-1989, n = 120). The data contained details on etiology, injury types and treatment delivered for 450 injured teeth (247 historic, 203 recent). RESULTS: In both cohorts, the occurrence was more common in males than females (63%/55%, resp.) with an age peak from 2 to 6 years. Maxillary incisors were most affected (89.6%/88.6%, resp.) and periodontal ligament injuries dominated (77.8%/90.3%, resp.). Almost half of the injuries occurred at home (46.6%), mostly due to falling (48.5%) or during playing (37.8%) in the recent paediatric cohort which provided better forensic data due to insurance issues and potential concern about child abuse. Advice and follow up was the most common approach in the recent paediatric cohort (76%). CONCLUSION: Even after 30 years and a change in the health care system due to German unification, the patterns of dental traumatic injuries in the primary dentition were similar.

Parental acceptance of advanced behaviour management techniques in paediatric dentistry in families with different cultural background.

PURPOSE: To investigate the differences of parental acceptance of advanced behaviour management techniques (BMT) in different cultural backgrounds (Germany vs. Jordan). METHODS: A convenience sample of 100 parents each of paediatric patients at the University of Greifswald/Germany and Jordan University/Jordan completed a questionnaire to rate their acceptance of four advanced BMT (passive restraint, active restraint, nitrous oxide sedation, and general anaesthesia) using a five-point Likert scale. RESULTS: In both groups, nitrous oxide sedation was the most accepted advanced BMT (mean 3.78 ± 1.34/3.22 ± 1.50, respectively). The least acceptable technique in Germany was passive restraint (2.05 ± 1.18) and in Jordan general anaesthesia (2.11 ± 1.30). The parents in Germany are significantly more accepting of nitrous oxide sedation than are parents in Jordan (p = 0.010), while parents in Jordan are more willing to accept passive restraint (p = 0.001). The acceptance of all advanced BMT increased significantly in both groups when the treatment was urgent. CONCLUSIONS: Parental cultural background and the urgency of the treatment affect the acceptance of different BMT. Moreover, the parental attitude to the pharmacological technique has changed, as nitrous oxide sedation generally appears to be the most preferred advanced technique in both groups.

Ten-year trends in DMF-S and DMF-T in a northeast German adult population.

OBJECTIVE: The aim of this study was to assess 10-year trends in coronal caries in adults aged 20-83 years using data from the two-representative population-based Studies of Health in Pomerania (SHIP-0/SHIP-Trend-0). METHODS: Repeated cross-sectional data from 4,286 SHIP-0 and 3,913 SHIP-Trend-0 participants were analysed. Carious, filled and missing teeth/surfaces were recorded in a half-mouth design and the DMF-T/S scores and sound surfaces/teeth were calculated according to WHO criteria. Trends in DMF-T/S scores and its single components were presented stratified by age group and sex. RESULTS: A statistically significant decline in coronal caries experience (DMF-T and DMF-S) in adults aged 20 to 83 years as well as for D-T/S components was observed. The proportion of edentulous participants was almost halved from 8.7% (SHIP-0) to 5.1% (SHIP-Trend-0), while the number of M-T declined from 4.4 to 3.5 revealing an overall clear shift to a higher retention rate of teeth. In younger adults (25-34 years) 3.8 more sound teeth (17.2 sound surfaces) were found in average in the mouth and in elderly (65-74 years) a clear shift from extracted to filled teeth was observed (M-T reduced by 5.4, while F-T increased by 4). Regarding sex differences, females had consistently on average higher MF-T/S values, but lower D-T/S values than males. CONCLUSION: A clinically relevant drop in the severity of coronal caries experience in all adult age groups in Northeast Germany shows that not only reductions in caries experience in adolescence translated into adulthood but also later improvements led to long-term oral health.

Sealants in dentistry: outcomes of the ORCA Saturday Afternoon Symposium 2007.

Sealants are a successful tool in caries prevention, but their role in preventive strategies after the caries decline has to be discussed. A survey of paediatric departments across Europe revealed that indications for pit and fissure sealants vary considerably, both nationally and internationally. Evidence for effectiveness of sealants in controlling caries in posterior teeth implies that sealants should be an integrated part of management of pit and fissure caries. Still, the indication for occlusal sealants seems to be shifting from primary prevention to a therapeutic decision for caries management of lesions in enamel and the outer part of the dentine. Sealants are also an interesting concept for caries management in approximal surfaces. Clinical trials suggest that novel techniques of sealing or infiltrating approximal lesions show promise. However, approximal sealing techniques are as complex to apply and time-consuming as approximal fillings. The article proposes guidelines for teaching on the use of sealants.

[Pain and pain management for children in Greifswald and East Pomerania: comparison with the results of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS)]. / Schmerzen und Schmerzmanagement bei Kindern in Greifswald und Ostvorpommern: Vergleich mit den Ergebnissen des Kinder- und Jugendgesundheitssurveys (KiGGS).

AIM OF THE STUDY: Pain in children and adolescents in Germany is a common health problem which has a high socioeconomic impact. There have been no studies allowing a reliable estimation of the prevalence of pain in children in the 5 (th) grade (age range 9-13 years) in schools in the region of the city of Greifswald and the administrative district East Pomerania. This population-based cross-sectional study examined the prevalence of pain in children, the treatment of pain and compared these data with the results of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS). METHODS: Data were collected within the extended dental school examination in autumn 2007 including a self-completion questionnaire for the students. Also the parents answered a self-completion questionnaire containing questions on their children's socio-economic status. The pain and sociodemographic questions are compatible with those used in the "German Health Survey for Children and Adolescents" (KiGGS). RESULTS: Students from 19 schools completed a questionnaire on general pain (n=852, proportion of response: 93.2%, mean age: 10 years). Comparing to the KiGGS the overall 3-month prevalence is much higher (95.5%). For boys and girls headache is the pain associated with the most burden ("Hauptschmerz"). 1/4 of the girls (27.9%) and 1/5 (22.4%) of the boys reported their pain with the most burden during the last 3 months with a frequency of at least one time per week. Students with low socio-economic status took medication against pain ("Hauptschmerz") less frequently than students with high socio-economic status. Because of their pain ("Hauptschmerz") students with low socio-economic status visited a doctor less often than students with a mean or high socio-economic status. CONCLUSION: Compared to other epidemiological studies, pain is also a common health problem for children in the city of Greifswald and the administrative district East Pomerania. The data base enables comprehensive conclusions on the health-related state of students in Greifswald/East Pomerania. Further studies should examine additional factors on medication and the degree of doctor?s visits, e. g., parental attitudes towards medication and parental motivation towards the degree of visiting a doctor.

Choosing a paediatric dentist: Factors influencing parents' decision.

AIM: Choosing a paediatric dentist is an important decision for parents. The mechanisms of this selection have hardly been studied. This study assesses the factors influencing parents' decision choosing a specialised paediatric dentist for their child. MATERIALS AND METHODS: A questionnaire consisting of 30 items that could potentially be relevant to decision-making was sent nationwide in Germany to paediatric dentists to be given to the parents of new patients (n=450). Eighty-nine out of 102 returned questionnaires (response rate=22.7%) were evaluated. RESULTS: Parent's and children's experience in previous dental visits played an "important" or "very important" role in choosing a paediatric dentist (78.8% and 62.2%, respectively). The most frequently mentioned recommendation for the paediatric dentist was by friends and acquaintances (86.5%). Recommendations from other dentists were often included in the decision making (60.7%), while specialist journals or Internet portals were less important for the respondents (15% and 19%, respectively). Most of the parents used Internet search engines and the practice website to obtain information. CONCLUSION: Previous negative experience with general dentists was the main reason for visiting a specialised paediatric dentist. Recommendations came mostly from the close social environment and the qualifications were the most important feature for choosing a paediatric dentist.

Dental characteristics and according treatments of children under GA in Germany.

PURPOSE: Due to rising numbers of dental referral to general anesthesia, more specialized dental treatments under GA were needed in the last decades in Germany. However, there are few studies about it. Therefore, the present study aimed to assess dental treatment and characteristics of the children underwent GA at Greifswald University Clinic in comparison with specialized pediatric private practices in Germany. MATERIALS AND METHODS: This analytical comparative research reviewed the records of all children younger than 18 years old, whose underwent GA at the university dental clinic and three private practices in 2011. All cases were analyzed anonymously, including age, gender, caries levels, diagnostics and dental treatments. RESULTS: About 54% and 50%, respectively, of children who underwent GA at both the university clinic and private practices were under 5 years old. Dental caries were mostly diagnosed among referred children (47.4% and 33.8% at university and private practices, resp.) followed by irreversible pulpitis (19.2% and 22.4%, resp.) and ECC (14.1% and 20.1%, resp.). Dental extractions were often performed at university clinic (40.2%) followed by fillings (33.9%), while more restorations and less extractions were supplied at private practices (47.8% and 16.3%, resp.). CONCLUSIONS: Dental caries and its complications like pulpal problems were the most important reason for children who underwent GA combined with young age (< 5 years). Therefore, a primary preventive approach would be preferable to decrease the number of children in need of comprehensive dental treatment under GA.
