“…Performing a full orthodontic assessment to ascertain treatment need in various ethnic groups may be a more valid assessment. 12 This may be especially true in populations in which bimaxillary protrusion is more prevalent since several occlusal traits common to bimaxillary protrusion are not represented in the IOTN. 13 An additional critique of the IOTN is that it deals solely with dental malocclusion rather than facial aesthetics.…”

Objective The objective of this study was to assess the validity of the IOTN-AC in the assessment of aesthetic impairment in bimaxillary protrusion patients. Materials and methods A cross-sectional study was conducted and involved 110 patients comprising 52 males (47.3%) and 58 females (52.7%) who were accepted for fixed appliance treatment at The University of the West Indies Dental Hospital and provided consent for the use of their records. The mean age was 13.45 years. Participants were asked to complete a questionnaire regarding their reasons for seeking orthodontic treatment and score their self-perceived IOTN-AC. An orthodontist also scored the malocclusion using the IOTN (AC and DHC). Results Spearman’s correlation between patient IOTN-AC and orthodontist IOTN-AC was r = 0.435, (p < 0.001). However, the patient IOTN-AC and the ‘normative’ need (p = 0.198), as well as the orthodontist IOTN-AC and the ‘normative’ need (p = 0.334), were not correlated (r = 0.124 and r = 0.094, respectively). Both patient and the orthodontist IOTN-AC scores were not in agreement with ‘normative’ need (IOTN-DHC). Cohen’s kappa test determined an agreement between the patient’s IOTN- AC and an orthodontist’s IOTN AC score, k = 0.395, p < 0.001. The questionnaire revealed aesthetics as the primary reason for seeking treatment but there was poor correlation between the questionnaire items and the patient or orthodontist IOTN-AC score, an AC score of 3 being the most common score for both. Conclusion The IOTN-AC is not a valid tool to determine patient perception of the need for treatment in a bimaxillary protrusion population when scored by either patients or orthodontists.

“…14 In the present study, the participants presented a facial profile described as bimaxillary protruded as a result of bimaxillary prognathism (prognathic maxilla and mandible) and bimaxillary proclination (proclined upper and lower incisors). 12 The cephalometric norms for this sample had been previously published. 12…”

“…Trinidad and Tobago is a cosmopolitan society with a unique composition of people that epidemiologically has already demonstrated some distinctive characteristics because of its diverse genetic pool [7][8][9][10]. Therefore, it is thought that the degree of expression and prevalence of dental anomalies in this cosmopolitan society can provide vital information for clinical dentistry, genetic and phylogenic studies allowing for a better understanding of variations in the epidemiology of dental anomalies between and within different societies [11].…”

Background: Dental anomalies entail an extensive range of disorders. This study aimed to ascertain the prevalence of several anomalies detectable on orthopantomograms and determine associations with ethnicity and gender. Methods: A retrospective review of 581 orthopantomograms and patient files was conducted. The prevalence of various anomalies was determined and the differences in ethnicity and gender were calculated using the chi-square test.Results: The study comprised 269(50.2%) males and 267 (49.8%) females with an age range of 5 -16years. 264(49.3%) participants were Afro-Trinidadians, 146(27.2%) were Indo-Trinidadians, and 126 (23.5%) were of mixed ethnicity. The overall prevalence of dental anomalies was 75.2%. No statistically significant correlation was found between the occurrence of dental anomalies and gender. A correlation was found between ethnicity and missing canines, impacted molars and other impacted teeth, and microdontia, with the mixed population having more anomalies. The impacted canine was the most prevalent anomaly. 44% of participants presented with one anomaly, and 24.81% of participants had two anomalies. Conclusion: There was a high prevalence of dental anomalies in the Trinidad and Tobago population. There was an association with some anomalies and ethnicity and no association with gender. The presence of dental anomalies should be considered when assessing diagnosing and treatment planning treatment planning patients in this country.

Introduction Attitudes towards and willingness to accept alternatives for sustainable dentistry in Trinidad and Tobago have never been assessed. Market research aids in the understanding of the behaviours of people. Since change can be enacted by public pressure, it is worth engaging the public through research to understand their attitudes and which changes they are willing to accept. Method A self-administered questionnaire was distributed to private and public dental clinics. The questionnaire assessed attitude towards and willingness to accept alternatives which decrease the effect of dental treatment on the environment. Results The study consisted of 1267 participants. Participants were mostly female, older, employed and mainly of African descent. Participants reported a very positive attitude towards sustainable dentistry (Mean = 3.89, SD = 0.8). and were moderately willing to accept alternatives such as a longer appointment time (Mean 3.47, SD = 0.73) and pay more for their dental treatments (Mean=3.00, SD = 0.87). There was a strong positive correlation with attitudes to sustainable dentistry and participants willingness to accept alternatives such as a longer appointment time (r = 0.658, p < 0.05). Conclusion The adult population had an overall positive attitude towards sustainable dentistry and was willing to accept alternatives so that their dental treatment would have less impact on the environment.
