Prevalence Of Crowding Research Articles

Prevalence of Dental Crowding in the Kabul Dental Hospital, Kabul-Afghanistan

Background: Dental crowding, also called overcrowding, is a condition in which there is not enough space in the mouth for the steady growth of permanent teeth. Common problems that crowding can cause for a person include difficulty chewing food, speech problems, tooth decay, enamel loss, premature tooth loss, pressure on the jaws and pain, gingival resorption, and tenderness. Crowding always creates an unpleasant appearance for a person and even causes a person to be isolated from society and reduce self-confidence due to an ugly appearance. Crowding raises serious functional and aesthetic concerns for many patients.
 Aims: Conduct a descriptive study in this field with 1000 patients of the (OPD) Outpatient Department of Kabul Dental Hospital on the prevalence of crowding and to finding the relationship between the incidence of crowding according to the upper and lower jaws and the anterior and posterior segments of each jaw.
 Methods and materials: The sampling method were systematic random sampling that 1000 people were randomly selected from all OPD service clients during nine months and were included in the study. The required information was obtained by clinical examination of patients above the dental unit, under adequate light and the kit of dental examination equipment with direct clinical examination of the patient, and a pre-prepared questionnaire was inserted.
 The information obtained from the questionnaire reached the coding page, and it was entered into IBM_SPSS-25 software, and its analysis was performed.
 Results: From the results of this study, it was found that the prevalence of crowding was 59.1%, with the highest incidence of 28.6% in the lower jaw. Also, the highest rate of crowding events was 44.9% in the anterior segment of the mandible. Crowding events were received in the upper jaw 12.7%, with the highest incidence of 29.3% in the anterior segment.

Prevalence of spacing and crowding in permanent dentition among patients visiting a private dental hospital

Malocclusion can be defined as an occlusion in which there is a mal relationship between the arches in any of the planes or one in which there are anomalies in tooth position beyond the normal limits. The literal meaning of malocclusion is a bad bite. People equate good dental appearance with success in many aspects. With the increasing demand for orthodontic treatment, the epidemiological data of malocclusion is essential in assessing the resources for orthodontic services. To assess the prevalence of spacing and crowding in the permanent dentition of patients visiting a private dental hospital. This study was based on data of patients who reported to the Department of Orthodontics, in a private teaching hospital in Chennai, India which was collected by reviewing patients records and analysing the data of 86000 patients. The data consisted of treatment done for spacing and crowding of permanent teeth in both arches in patients of age 12 to 25 years. Prevalence of crowding (64%) was more common than spacing (36%) indicating that crowding is the most common anomaly in both maxilla and mandible. Both maxilla and mandible showed statistical significance for age and gender. This study reveals that crowding is the most common anomaly in both arches.

Prevalence of crowding, boarding and staffing levels in Swedish emergency departments - a National Cross Sectional Study

BackgroundEmergency Department (ED) crowding occurs when demand for care exceeds the available resources. Crowding has been associated with decreased quality of care and increased mortality, but the prevalence on a national level is unknown in most countries.MethodWe performed a national, cross-sectional study on staffing levels, staff workload, occupancy rate and patients waiting for an in-hospital bed (boarding) at five time points during 24 h in Swedish EDs.ResultsComplete data were collected from 37 (51% of all) EDs in Sweden. High occupancy rate indicated crowding at 12 hospitals (37.5%) at 31 out of 170 (18.2%) time points. Mean workload (measured on a scale from 1, no workload to 6, very high workload) was moderate at 2.65 (±1.25). Boarding was more prevalent in academic EDs than rural EDs (median 3 vs 0). There were an average of 2.6, 4.6 and 3.2 patients per registered nurse, enrolled nurse and physician, respectively.ConclusionED crowding based on occupancy rate was prevalent on a national level in Sweden and comparable with international data. Staff workload, boarding and patient to staff ratios were generally lower than previously described.

Tek taraflı dudak ve damak yarığına sahip hastalarda alt çene ark boyu uyumsuzluğu: ortodontik model analizi

Objective: This study aimed to assess the lower arch length discrepancy in a group of patients with unilateral cleft lip and palate (UCLP). Materials and Method: Pretreatment dental casts and panoramic radiographs of 23 patients (aged 9–19 years) with a nonsyndromic complete UCLP, without having large restorations/crowns, tooth agenesis, impacted or supernumerary teeth in the lower arch, and previous orthodontic and/or prosthetic treatment, were evaluated. All patients underwent lip and palate repair. Lower arch discrepancies were determined using the Hayes-Nance analysis. Panoramic radiographs were used to estimate the size of permanent premolars for the patients with late mixed dentition. The positive discrepancy defined diastema, whereas the negative discrepancy defined crowding in the lower arch. Descriptive statistics were presented using frequencies and percentages, and the differences were evaluated using the binomial test. Results: One out of 23 patients had no discrepancy in the lower arch. For the remaining patients (n = 22), the prevalence of diastema was 47.8% (n = 10), with a mean value of 3.6 ± 1.9 mm, and lower arch crowding was observed in 52.2% (n = 12), with a mean value of –2.9 ± 1.4 mm. No significant difference was found between the prevalence of crowding and diastema (p = 0.832). Conclusion: In patients with a UCLP, diastema can be encountered approximately at the same frequency as crowding in the lower arch. Crowding was at a low to mid-level.

The prevalence of malocclusion and its gender distribution among Indian school children: An epidemiological survey

Context: Since antiquity malocclusion is a problem. People have different perception about the problem which varies according to their geographical location and cultural background. The problem of malocclusion is more severe in developing countries like India. It can compromise the oral health tissues and can lead to social and the psychological problems. Aims: To assess the prevalence of malocclusion and its gender distribution among the Indian school children. Settings and Design: School settings and Descriptive cross-sectional survey. Materials and Methods: A cross-sectional epidemiological survey was conducted in all the 30 districts of Karnataka, India. School children in the age group of 10-16 years were the target population. Population proportionate technique was employed for the sample size estimation. A total sample of 9505 was randomly selected from 102 schools all over Karnataka, India. Ackermann-Proffit classification of malocclusion was used to record the malocclusion. Statistical analysis used: Simple Descriptive statistics. Results and Conclusion: Prevalence of crowding is 50.4% in boys and 51.4% in girls. Cross-bite was reported in 17.8% and 18.3% in boys and girls, respectively. Angles class I malocclusion was reported in 78.4% of boys and 80.2% of girls. Angles class II malocclusion was reported in 21.5% of boys and 19.8% of girls and class III malocclusion was observed in 0.1% of boys.

Assessment of Malocclusion in school children of Karnataka State between the age groups of 10-12 years and 13-16 years. A Crosssectional Descriptive Survey.

Context: Malocclusion can compromise the oral health tissues and can lead to social and psychological problem. Hence an investigation of the malocclusion status at the developing stages of the dentitions to intercept the same is required.

Ackermann-Proffit classification of malocclusion was used to record the malocclusion. Statistical analysis used: Simple Descriptive statistics. Results and Conclusion: Prevalence of crowding is 52.3% in mixed dentition and 50.2% in permanent dentition. Cross-bite was reported in 17.4% and 18.3% in mixed and permanent dentition respectively. Increased over-jet was reported in 15.3% and 7.7% in mixed and permanent dentitions respectively.
