Abstract
OBJECTIVES To examine, in relation to changes in national guidance, trends in the provision of general anaesthesia for exodontia in children. DESIGN Retrospective analysis of hospital records. SETTING University Dental Hospital, Cardiff, UK. METHODS Data were drawn from records of services provided in each of four index months during 1989, 1991, 1997 and 1999 (the years immediately preceding/following the Poswillo Report of 1990 and the General Dental Council's revised guidance of 1998). RESULTS In the first year after publication of the Poswillo report, there was a 19.6% increase in use of 'chair case' general anaesthesia over the four index months. Subsequently, upon the emergence of additional providers, patient flow in 1997 had fallen to 65.8% of that seen at baseline. Following the General Dental Council's revised guidance of 1998, there was a further reduction in the provision of 'chair case' general anaesthesia (to 40.8% of that seen at baseline). CONCLUSIONS In this unit, throughput of children receiving general anaesthesia for exodontia has fluctuated in periods marked by changing national guidance. However, it is not possible to attribute such fluctuations in patient flow solely to this factor.

Abstract
OBJECTIVE To investigate trends in oral surgery in England and Wales 1991-2000. METHODS Oral surgery procedure data were derived from Dental Practice Board and Department of Health Hospital Episode Statistics. RESULTS There was a 6% increase in minor oral surgery (MOS) procedures, including ordinary extractions, extractions of special difficulty, apicectomies and third molar removals, carried out in the General Dental Services (GDS) but the number of third molars removed fell by 32% after 1997. General anaesthetics (GA) administered in the GDS fell by 77% and the number of sedations rose 54% after 1998. There was concentration of minor oral surgery in practices: in the year 2000, 88% of practitioners carried out less than five third molar removals. In the Hospital Dental Service (HDS) there was a 98% increase in day surgery, and a 53% decrease in ordinary admissions for minor oral surgery. HDS waiting times remained constant over the ten year period. CONCLUSIONS The principal trends were substantial decreases in apicectomies, third molar removals after 1997 and GAs after 1998; increases in extractions of special difficulty and concentration of MOS in the GODS. Numbers of ordinary extractions did not change. In the HDS there was a large shift from in-patient to daycase provision which has facilitated expansion of maxillofacial surgery. This is an important example of NHS reconfiguration. Perhaps the most important implication of these changes concerns the place of MOS in vocational training.

Abstract
PURPOSE Oral and maxillofacial surgeons devote a large portion of their practice to the removal of impacted teeth. Many of these teeth have associated soft tissue that is submitted along with or without the tooth for histopathologic examination. This study reports the histopathologic diagnoses of a large series of pericoronal lesions in adults submitted to an oral and maxillofacial pathology biopsy service. MATERIALS AND METHODS Two thousand six hundred forty-six pericoronal lesions received during a 6-year period were reviewed for location, age, and histopathologic diagnosis. RESULTS Retrospective evaluation showed that 67.1% of all submissions were nonpathologic follicular tissue. Pathologically significant lesions were diagnosed in 32.9% of cases. Among these lesions were 673 dentigerous cysts (28.4%), 79 dentigerous cysts with mucous cell prosoplasia, 71 odontogenic keratocysts (2.68%), 19 odontomas (0.7%), 13 ameloblastomas (0.5%), 6 carcinomas (0.23%), 6 calcifying odontogenic cysts (0.23%), 4 calcifying epithelial odontogenic tumors, and 1 odontogenic myxoma (0.04%). When stratified by age, the data showed pathologically significant lesions and age are related (chi(2), P <.0001). CONCLUSIONS Because of selection bias inherent in a study of this nature, population generalizations cannot be made. However, this study serves to show that the potential for the development of significant, even life-threatening, disease associated with impacted teeth is real and should be a factor in the decision-making process when oral surgeons and others are confronted with the dilemma of managing an impacted tooth.

Abstract
This study compares oral health status and its inequality among education groups across seven study sites in five countries: Erfurt, Germany; Lodz, Poland; Yamanashi, Japan; New Zealand; and Baltimore and the Lakota and Navajo Indian Health Service sites in the United States. The data, from the International Collaborative Study of Oral Health Outcomes, were collected through personal interviews and clinical examinations. The research group measured the study sites' overall oral health, examining the percentage of the population with five or more missing and two or more decayed teeth. The group also assessed the magnitude of inequality among education groups by using indices of excess morbidity. Baltimore had the lowest percentage (10.8 percent) of decayed teeth and second lowest percentage (17.3 percent) of missing teeth, but the greatest indices of excess morbidity (79.2 percent for missing, 73.1 percent for decayed). Lodz, by contrast, had the worst overall dentition status (75.3 percent for missing, 70.3 percent for decayed) but the lowest inequality indices (10.6 percent for missing, 13.8 percent for decayed). This study demonstrates the need for policymakers in the study countries to consider not only overall levels but also the distribution of oral health, and it presents various challenges for oral health professionals in designing and implementing oral health programs.

Abstract
The present study was carried out on 2005 school going children between 11-15 years of age, studying at Belgaum city. The sample was selected by stratified random sampling method. The examination was done under natural light and caries was diagnosed according to WHO criteria (1987). The prevalence of dental caries in the present population was 45.12%. The mean DMFT was 1.18. Males and low socio-economic groups showed a higher prevalence, though the difference was not significant. Intraoral distribution of caries pattern has also been discussed. The treatment needs showed that 57.94% of affected teeth required single surface restorations. The needs for other treatment modalities have been discussed in relation to the dental caries prevalence. The results of this study call for more emphasis on restorative care for these children at primary level.

Abstract
The objectives of the study were: 1) to describe the choice of dental care system among 16-year-olds, 2) to describe the utilization of dental services among 16-17-year-olds enrolled in either public or private dental care systems, and to compare the dental services provided by the alternative systems. The study comprised 1,245 adolescents from 3 municipalities; the historical cohort study design was applied; and data were collected from dental records (public dental service) and dental claims (private practice). At age 16, 12% preferred being enrolled in the private practice system, while 88% remained in the public dental care system. During the 2-year study period the attendance rate was 99% for the public system, while 90% attended the private practice system (P< 0.001). Preventive dental services were provided more frequently by the public than the private system (P< 0.001). Despite the fact that the economic barrier was eliminated a lower attendance rate was observed for patients transferred to the private practice system.

Abstract
Seventy-five Nigerian dentists were interviewed on their approach to the management of impacted third molars. The mean age of the dentists was 34.8 years, with a male/female ratio of 3.4:1. Most of the female dentists were found in the training institutions (p = 0.005). More than half of the dentists (58.7%) practiced in institutions with dental schools (training institutions), majority preferred the buccal approach (92%), and all the dentists (100%) preferred third molar disimpaction under local analgesia. Most dentists (88%) prescribe antibiotics following third molar surgery. Fifty dentists (66.7%) routinely reviewed all patients postoperatively while 12 dentists (16%) were of the opinion that all impacted third molars should be extracted. Only 21 dentists (28%) were aware of any protocol on the management of impacted teeth. More dentists in the training institutions performed third molar surgery less frequently than dentists in other hospitals (p = 0.07) who tend to employ chisels/mallet for bone removal (p = 0.0004). The need for continuing education and the formulation of guidelines in order to assist dentists to make informed decisions is emphasised. This will help conserve scarce resources and enhance the operation of the newly introduced National Health Insurance Scheme.

Abstract
OBJECTIVE To study predictors of dentists' recommendations to replace the teeth which they extracted for adult patients in Norway in 1998. DESIGN Cross-sectional postal questionnaire survey. PARTICIPANTS A systematic random sample of 1,500 Norwegian general dental practitioners and response rate of 67% after two reminders. After exclusions, 302 dentists who had extracted 822 permanent teeth for 587 patients (16-92 years old) over a period of two weeks, were accepted for the study. RESULTS According to the dentists, 30% of the patients were in definite need of a replacement for the extracted tooth or teeth, 29% were cases open to question and 41% had no need for a replacement. Model I: Tooth type extracted and the number of teeth extracted per patient were the most important predictors of the dentists definitely recommending a replacement after tooth extraction. Model II: When including the group of patients for whom a replacement was open to question, the odds of the dentists recommending a replacement for having an extracted anterior tooth or premolar increased from 13 (95% CI 6.16, 26.07) to 21 (95% CI 10.51, 40.69). Demographic characteristics had no significant effect on the dentists' decision. CONCLUSIONS The two most important predictors for recommending a replacement after extraction were the position of the tooth or teeth and the number of teeth extracted. The reason why the number of remaining teeth had no significant independent effect was possibly because this group of patients had a relatively high number of natural teeth.

Abstract
OBJECTIVES To analyse the antibiotic prescribing trends for exodontia and minor oral surgery in patients with a history of radiotherapy. Also, to evaluate the use of hyperbaric oxygen as a separate modality in the prevention of osteoradionecrosis. DESIGN A survey of antibiotic prescribing involving the analysis of a questionnaire which included the management of three patients with a history of head and neck malignancy. METHOD The heads of the departments in each unit in the UK were sent a closed-response questionnaire. Antibiotic prescribing was assessed in three case scenarios. Case one referred to a patient that had surgery alone as part of the management of head and neck cancer, who needed the surgical removal of second molar roots. Case two referred to a patient that had surgery and adjuvant radiotherapy as part of the management of head and neck cancer, and needed the same procedure as in case one. Case three included a patient with a history of surgery and adjuvant radiotherapy, who required the extraction of three mobile and periodontally-involved lower incisors. Consultants were also asked about the use of hyperbaric oxygen in the patients who had radiotherapy as part of their treatment strategy. RESULTS A total of 109 questionnaires were sent to all the Maxillofacial Units in the UK. The response rate was 73%. In patients with a history of radical surgery alone for the management of head and neck cancer, 20% of the surgeons advocated pre-operative antibiotics for the surgical removal of lower posterior teeth. In contrast, in the patient with a history of adjuvant radiotherapy 86% supported pre-operative antimicrobial use for the surgical removal of the same teeth. In the extraction of mobile and periodontally involved lower incisors in the previously irradiated patient, 63% of the clinicians supported pre-extraction antibiotics. Postoperative antibiotics were advocated in 52% in the first case, 89% in the second case and 71% in the third case. 34% of the clinicians advocated hyperbaric oxygen for surgical removal of posterior teeth and 15% for the extraction of mobile anterior teeth. CONCLUSIONS The use of peri-extraction antibiotics was favoured among oral and maxillofacial surgeons. There was little enthusiasm towards the use of hyperbaric oxygen as a prophylactic measure, alone or in conjunction with an antimicrobial regime. Control randomised trials that will measure the effectiveness of hyperbaric oxygen and the appropriate use of antibiotics for prophylaxis in pre- and post-operative regimes are necessary to evaluate the use of these modalities.

Abstract
Ninety-six patients, fifty-eight healthy patients and thirty-eight special needs patients, ranging in age from 3 to 31 yr (average age 6.9 yr) had received dental treatments under general anesthesia (GA) at Amiri Hospital. The mean number of dental procedures per child was 13.6 (SD+/-5.4) with a mean number of 15.6 procedures for healthy patients and 10.5 special needs patients. There was a statistically significantly higher number of dental procedures for healthy patients than for special needs patients (p<0.001). The number of pulpotomies and stainless steel crowns placed for healthy patients was significantly higher (3.5) than for special needs patients (1.3) with (p<0.001) The average number of extractions was similar for the two groups of patients, 2.8 for normal and 2.2 for handicapped. On the basis of these results, it was concluded that dental treatment under GA in hospital environment is beneficial for certain group of patients, such as very young children and those with special needs. Underlying medical conditions influenced the treatment provided.

Abstract
INTRODUCTION Most dental treatment for children in the United Kingdom (UK) is provided by general dental practitioners (GDPs) working in the National Health Service (NHS). A working party of the British Society of Paediatric Dentistry, in a special publication from the Dental Practice Board, has suggested that failure to provide restorative care for the deciduous dentition is unacceptable, yet GDPs are filling fewer teeth in young children. The study aimed to evaluate the health outcomes obtained from restoring carious deciduous molar teeth. METHOD The dental records of 677 children cared for by 50 GDPs in the north west of England were analysed. RESULTS The results showed that 18.8% of deciduous molars with unrestored caries and 17.0% with a history of restorative care went on to be extracted because of pain or sepsis. CONCLUSION The results suggest that the risk of carious deciduous molars being extracted is similar whether these teeth receive restorative care or not.

Abstract
Studies have suggested that formocresol has toxic and carcinogenic potential. A search for an alternative medicament for primary tooth pulpotomies has led to ferric sulfate as a possible alternative. A retrospective study was done in a multipractitioner IHS (Indian Health Service) clinic. Radiographic success or failure was determined for 202 primary tooth pulpotomies performed with either formocresol, ferric sulfate, or a combination procedure of formocresol and ferric sulfate. The post-operative period for the pulpotomies ranged from one month to thirty-six plus months. There was no statistical difference in radiographic failure rates between formocresol, ferric sulfate, or the combination procedure when results were analyzed regardless of post-op period. However, when post-op periods were considered, formocresol performed better at > 36 months and the combination procedure showed significantly more failures at > 36 months.

Abstract
The difference between paediatric dentistry and most other branches of dentistry is that in the child the occlusion is changing. Consequently 'Good Occlusal Practice' in children is a matter of making the right clinical decisions for the future occlusion. The clinician needs to be able to predict the influence that different treatment options will have on the occlusion when the child's development is complete.

Abstract
Selected outcomes following initial nonsurgical root canal treatment (NSRCT) procedures were retrospectively assessed using an insurance company database of 110,766 nonsurgical root canal procedures that were completed by endodontists and their referring general dentists. A subset of 44,613 cases, with a minimum required follow-up time of 2 yr, showed incidences of extraction, retreatment and periradicular surgery equal to 5.56%, 2.47%, and 1.41%, respectively. The incidence of subsequent extraction increased with patient age. Teeth that were not restored after root canal therapy were significantly more likely to undergo extraction than restored teeth. Although the practice pattern for endodontists consisted of a significantly higher proportion of molars (48% more; p < 0.001) and a smaller proportion of anterior teeth (43% less; p < 0.001) than general dentists, both groups of providers had comparable rates of untoward events. These data strongly support the hypothesis that the specialist practice provides similar rates of clinical success compared with other providers, even when treating significantly more complex NSRCT cases. Overall, 94.44% of nonsurgical root canal treated teeth remained functional over an average follow-up time of 3.5 yr. These results are an important indication of the benefits of endodontic treatment when provided in an integrated health care delivery system of endodontists and their referring general dentists.

Abstract
In 1999, an oral health survey was included in an assessment of the community oral health programme of the Tokelau Islands population. This provided a comparison with a similar survey in 1963. In a convenience sample of 386 children and adults, approximately 30 percent of the total population, the deciduous (number of df teeth) and permanent (number of DMF teeth) tooth scores across all age groupings were higher in 1999 compared with 1963. For 15- to 19-year-olds, the mean DMF scores were 8 and 1; and for 35- to 44-year-olds, the scores were 18 and 4 in 1999 and 1963 respectively. The prominent feature of the DMF scores for those over age 25 years was the numbers of missing (M) teeth. The mean number of M teeth at 20-24 years was 5 and 0, and at 35-44 years, 13 and 2 respectively in 1999 and 1963. Periodontal disease was endemic in adults in both surveys. A serious decline in oral health has occurred over the past 35 years.

Abstract
This study aimed to examine the relative importance of invasive treatment experiences in the acquisition of dental fear in children. For this purpose, the complete dental history of 401 children (5-10 years) from 2 dental practices was studied. The level of dental fear in these children was assessed using the Dental Subscale of the Children's Fear Survey Schedule (CFSS-DS). Differences in treatment variables between high fearful and low fearful children were analysed, and regression analysis was performed to determine significant predictors of dental fear. A significant though weak relation of dental fear with the number of experienced extractions was found, while no relation with the number of experienced fillings was found. The results indicate that within the (direct) conditioning pathway, objective dental procedures seem to play a minor role in children's fear acquisition. Clinical support for the 'latent inhibition' theory was provided: a history of neutral or positive dental visits seems to serve as a defence against the development of dental fear in children.

Abstract
Mobile clinics are a cost-effective method of meeting the dental needs of rural communities in South Africa. Phelophepa, the first primary health care train of its kind world-wide, provides eye care, education, medicine, basic health care and since June 1995 dental treatment to rural communities. All services are rendered by students under supervision of qualified staff. The aim of this study was to analyse and report the data for treatment performed in the dental clinic from June 1995 to May 2000. During its first five years of operation, dental services were provided at 183 towns in all provinces except Gauteng. Of the 42,073 patients treated during this time (an average of 229.9 per town), 67.4% were adults. 71.3% of the 103,283 procedures performed were extractions, 15.7% could be classified as preventive with the remaining 13% as restorative procedures. The average value of the service provided to each patient was R218.53. The exposure of dental, dental therapy and oral hygiene students to rural areas of South Africa serves the important purpose of sensitising students to the realities of oral diseases in these communities.

Abstract
OBJECTIVE The purpose of this study was to describe the presence and impaction status of people's third molars at age 18 years, as well as the observed changes in their clinical status between ages 18 and 26 years. STUDY DESIGN Eight hundred twenty-one participants in a prospective cohort study were dentally examined at ages 18 and 26 years, and panoramic radiographs were taken at age 18 years but not at 26 years. For each tooth, its radiographic impaction status at age 18 years was compared with the clinical status by age 26 years. RESULTS Of the 2857 third molars assessed at age 18 years, 92.8% were able to be followed up clinically at age 26 years. Approximately 54.9% of the teeth that were not impacted by age 18 had erupted by 26 years. Of the teeth that were impacted by age 18, 33.7% had fully erupted by age 26, 31.4% had been extracted, and 13.1% remained unerupted. Of the maxillary teeth that were categorized as "impacted" at age 18 years, 36.2% had fully erupted by age 26, whereas only 25.6% of the mandibular teeth had done so (P <.01). Fewer mandibular teeth than maxillary teeth remained unerupted by the time the patient was 26 years old (27.4% and 41.4%, respectively; P <.01), but there was no significant difference between the jaws in the proportion of impacted teeth at age 18 years that had been extracted by age 26 years (29.6% and 30.3%, respectively). For mesioangularly impacted third molars, 39.3% of maxillary teeth and 20.4% of mandibular teeth had fully erupted by age 26. Of the third molars that were mesioangularly impacted at age 18 years, 39.3% of maxillary teeth and 20.4% of mandibular teeth had fully erupted by age 26 years, whereas almost one-third of each had been extracted. Of the distoangularly impacted third molars, 20.4% of the maxillary teeth and one-third of the mandibular teeth had erupted by age 26, with 21.6% of the maxillary teeth and 31.6% of the mandibular teeth having been extracted. CONCLUSION Other than horizontally impacted third molars, a substantial proportion of other impaction types do erupt fully, and radiographically apparent impaction in late adolescence should not be sufficient grounds for their prophylactic removal in the absence of other clinical indications.

Abstract
OBJECTIVES The aim of this survey was to investigate the reasons for extraction of the various tooth types in Scotland. This study replicated one which was undertaken 15 years earlier. A further aim, therefore, was to identify any changes in the frequency of extraction of each tooth type in the 15 years between the two studies. METHODS The names of every fourth dentist on the list of the Scottish Dental Practice Board were obtained. Four hundred and twenty-five general dental practitioners were asked to record permanent tooth extractions for 1 week. Data requested for each extraction were: the patient's age, gender and dental attendance pattern, the type of tooth removed and the reason for the extraction. RESULTS Three hundred and fifty-two dentists participated (a response rate of 82.8%). There were 25% fewer teeth extracted per patient and 30% fewer per dentist than in the 1984 study. In 1999, more teeth of most types were extracted from regular attenders whereas, in 1984, more teeth of all types were extracted from irregular attenders. Premolars and first and second molars were the tooth types most frequently extracted in both surveys. In 1999 premolars were the teeth most commonly removed below 21 years of age, accounting for 57.5% of extractions in this age range. Molars accounted for 33.8% of extractions in this age range compared with 52% in 1984. Overall, caries was found to be the principal reason for loss of all tooth types apart from lower incisors which were extracted mainly for periodontal reasons. However, below 21 years, 84.5% of premolar extractions were performed for orthodontic purposes. CONCLUSIONS Over the last 15 years, the overall number of extractions has reduced and the proportion of extractions from regular attenders has increased. Proportionately more premolars and fewer molars were extracted from under-21-year-olds. This observation can be explained by an increase in orthodontic extractions or a decline in extractions for caries in this age group. However, when extractions from the population as a whole are considered, caries and its sequelae remains the principal reason for loss of all tooth types other than lower incisors which are extracted mainly for periodontal reasons.

Abstract
OBJECTIVES In recent years, several critical outcome studies concerning the prophylactic removal of mandibular third molars have been published. These would appear to motivate a more restrictive approach today as compared with 10 years ago. The aim of the present study was to examine dentists' decisions on the prophylactic removal of impacted mandibular third molars over a 10-year period. METHODS Thirty-six cases were selected so as to represent an equal distribution of males and females, ages, angular position and degree of impaction of the molar. Twenty-six general dental practitioners (GDPs) and 10 oral surgeons judged the same cases on two occasions 10 years apart. RESULTS Calculated for each category of dentists, there was no significant difference in the mean number of molars designated for removal between the two occasions. Two GDPs and three oral surgeons presented a higher removal rate, whereas five GDPs presented a lower removal rate on the second occasion as compared to the first one. The dentists presented a considerable interindividual variation in removal rate, between 0 and 22 molars on the first occasion and between 0 and 25 molars on the second occasion. CONCLUSION In the decisions on prophylactic removal of mandibular third molars, there has been no change over the last 10 years towards a more noninterventionist attitude. Thus, the dentists seem not to have been influenced by the evidence that this intervention is not cost-effective.

Abstract
In the Netherlands, first permanent molars with idiopathic enamel disturbances (IED) are called cheese molars. Though concern is expressed about their prevalence, adequate figures on the subject are missing. The porous enamel of cheese molars can be very sensitive to cold air and can decay rapidly. The aim of the present study was to investigate the prevalence in eleven-year-old Dutch children of cheese molars (IED). During an epidemiological study performed in four cities in the Netherlands, the first permanent molars and central incisors of eleven-year-old children were examined for hypoplasia, opacities, posteruptive enamel loss, premature extraction, and atypical restorations. The observation of a hypoplasia excluded the possibility of cheese molar. A total of 497 children were examined. Six percent (n = 128) of the molars (n = 1988) showed signs of IED (cheese molars), 10 percent of the children had cheese molars of which 8 percent two or more. Incisors (4 percent) with opacities were found in 3 percent in combination with two or more cheese molars. Among the four cities, no significant differences in occurrence were found. The results of this study showed that in 10 percent of the Dutch children eleven years of age, cheese molars (IED) were found. The cause for the phenomenon called cheese molars appears to be child centered. Further studies on prevalence, causes and prevention are mandatory.

Abstract
This study compared the treatment provided for patients with supernumerary teeth in Bristol Dental Hospital with those in Westmead Dental Hospital, Sydney, Australia. The records of 63 children referred for removal of a supernumerary tooth in Bristol and 96 children in Westmead were examined, involving a total of 215 supernumerary teeth. Differences in the treatment provided for these patients were found not only between the two centres but also within one centre. There appeared to be no standardised route by which these patients were seen and therefore no standardised pattern of treatment. Contact with all UK Dental Schools indicated that no formal treatment protocol existed for the treatment of children with supernumerary teeth. In addition, a permanent incisor associated with a conical supernumerary tooth was twice as likely to erupt spontaneously as one associated with a supernumerary of tuberculate form. The location of the supernumerary tooth also influenced the likelihood of spontaneous eruption of the associated permanent incisor. There is a need for a prospective randomised controlled trial in the future in order to develop a formal treatment protocol for the management of patients with supernumerary teeth. A multicentre trial is under development.

Abstract
AIMS Although Scotland has the highest proportion of edentulous adults in the UK, the frequency of edentulousness has fallen by 21% during the last 20 years. This study, carried out in 1999, was designed to establish whether the reasons for tooth loss have also changed since 1984 when they were last determined. METHODS The Scottish Dental Practice Board provided the names of every fourth dentist on its list among which 425 general dental practitioners were identified. They were asked to record permanent tooth extractions for 1 week, specifying the age, sex and dental attendance of patients who underwent extractions and the reasons for these extractions. 352 dentists took part: a response rate of 82.8%. RESULTS The study confirmed that there has been a reduction in the number of extractions between 1984 and 1999: there were 25% fewer teeth extracted per patient and 30% fewer per dentist per week. From 0-20 years of age, orthodontics has replaced caries as the commonest reason for extraction and in all age groups over 20 years, caries has become the commonest reason in contrast to 1984 when periodontal disease was the principal reason in patients over 40 years old. CONCLUSIONS Caries and its sequelae remain the most important cause of tooth loss throughout adult life in Scotland and, therefore, caries prevention and maintenance of restorations are of great importance at all ages.

Abstract
OBJECTIVES Patterns of attendance at the Dublin Dental Hospital's Accident and Emergency Clinic in 1996 were compared with figures from 1993 to look for changes, especially in the light of changing provision of public funding for dental treatment for medical card holders and dependants. METHODS An audit of patient clinical records for one month in 1996 was compared to previously published data relating to 1993. RESULTS While patient numbers were similar in the two time periods (718 in 1993 versus 708 in 1996), the proportion of attendances by medical card holders or their dependants dropped from 48 per cent to 36 per cent. The proportion of non urgent treatments had also dropped over the three years. CONCLUSIONS Changes in the provision of publicly funded dental treatment for medical card holders and dependants has reduced the proportion of such patients attending the clinic. However, their places have been taken by other patients.

Abstract
This epidemiological investigation was carried out among 524 handicapped children in the age group of 3-30 years, attending 8 different non-residential special schools in South Canara district, Karnataka. The examination procedure and criteria were those recommended by W.H.O. in 1997. The total caries prevalence was found to be 71.56%. The mean deft in the primary dentition was found to be 3.06 +/- 3.14. The mean deft and DMFT in the mixed dentition were 3.32 +/- 2.82 and 1.14 +/- 1.08 respectively. The mean DMFT in the permanent dentition was 4.51 +/- 3.17. The prevalence of dental caries was higher in the mentally subnormal and handicapped children. The decayed component constituted the majority of the dental caries index. Lack of conservative approach to the treatment had been confirmed in the study.
