Malocclusion is one of the common dental problems reported in children that refers to the malalignment of the teeth or improper relationship of the dental arches due to altered developmental systems of the orofacial complex. Several studies have reported on the relationship between malocclusion and dental caries in which the presence of malocclusion such as crowding and spacing may act as predisposing factors in the development of dental caries. The aim of this study is to evaluate the prevalence of dental caries among 12-16 years old school children with malocclusion. It is a retrospective study conducted by reviewing 86,000 patient case records of the Saveetha Dental College and Hospital, Chennai, India. A total of 313 consecutive case records of patients for a period of June 2019 to March 2020 with signed informed consent were retrieved and analysed. Patient’s name, patient’s identification number (PID), age, gender, malocclusion and dmft score were collected from the patients’ case records. Data collection and analysis were done using the SPSS version 23.0. Descriptive analysis was done for the assessment of age, gender, malocclusion and dental caries. Chi square test was used to evaluate the association of dmft score with malocclusion. A total of 134 children with malocclusion were affected by dental caries (42.81%). The overall dmft score was 1.5. Most of the children present with dental caries were within the 12-14 years age group (60.45%), followed by those within the 15-16 years age group (39.55%). High prevalence of dental caries was seen in males (52.24%) as compared to females (47.76%). Most of the children had Class I malocclusion (70.93%), followed by Class II malocclusion (29.07%). In terms of crowding, mandibular crowding (57.19%) was more common among the children when compared to maxillary crowding (38.98%). There is a statistically significant association between maxillary crowding and dental caries. No association of dental caries with mandibular crowding and dental malocclusion. Within the limits of the present study, dental caries is seen in 134 of the patients with an average dmft score of 1.5. There is a positive association between maxillary crowding and dental caries but no significant association of dental caries with dental malocclusion and mandibular crowding.

Numerous studies in the past have been conducted to determine the prevalence of malocclusion in different populations. These show extreme variations and it is only right to determine the prevalence in a referred population. Class III malocclusion even though it is the least common, treatment planning and treatment is quite difficult, thus characteristics of class III malocclusion need to be studied in detail.The aim of the study is to evaluate the prevalence of crowding among patients with class III malocclusion visiting Saveetha dental college and hospitals. A retrospective study was done using case sheets of patients visiting the university hospital from June 2019- February 2020. About 100 case sheets of patients visiting the department of orthodontics containing information on malocclusion type and crowding was retrieved and analysed using SPSS 20.0. The study included 100 patients out of which 74% were males and 26% were females.Crowding was observed in 51% of the patients with class III malocclusion. Out of which 62.75% of the patients were reported to have minimal crowding ,31.37% had moderate crowding and 5.88% had severe crowding of the mandibular incisors. There was no statistically significant association between age, gender, and severity of crowding as determined by pearson's chi-square tests.Within the limits of the study, it can be concluded that mild mandibular crowding was the most common finding in class III malocclusion patients.

In the earlier days orthodontics was more focused towards rectifying a malocclusion.But nowadays there is a shift towards maintaining the balance between functional efficiency ,structural balance and esthetic harmony. Understanding the perspective of a patient's orthodontic treatment needs helps in better treatment planning.The aim of this study was to identify the major chief complaint of the patient seeking orthodontic treatment.In this retrospective study records of 900 patients undergoing Orthodontic treatment were obtained .Their chief complaints were screened and were classified into esthetics, pain and functional. Esthetics chief complaints were further subdivided into crowding, proclination and spacing
.Results showed that majority of the patients seek orthodontic treatment for esthetic reasons.Among esthetics crowding was found to be the major chief complaint, followed by proclination and spacing
