“…Bimaxillary dental protrusion or bimaxillary protrusion is a condition where the anterior teeth of the maxilla and mandible are protruded relative to the maxilla and mandible basal bones. [1][2][3] The characteristics seen are an incompetent lip in a resting position, an excessive effort to close the lips completely, thus creating lip strain and prominent lips. [1][2][3] Bimaxillary dental protrusion is affected by race and ethnicity.…”

Background: Management of bimaxillary protrusion can be challenging and should be used with maximum anchorage to prevent loss of anchorage and improve the facial profile. In addition, a patient with a missing molar is often found in a dental clinic. Space closure can cause tipping movement rather than bodily, so couple force should be used. Purpose: This case report aims to manage the bimaxillary protrusion with a missing molar using a T-loop and a transpalatal arch (TPA) as maximum anchorage for correction of the facial profile and couple force to create bodily movement for the space closure of a missing first molar. Case: A 21-year-old female patient complained about her protruding teeth. An intraoral examination indicated Angle’s Class I malocclusion on the left molar relation, with the lower-right first molar missing, mild crowding maxilla and mandible, 6 mm of overjet and 5 mm of overbite, and midline shift at the maxilla and mandible. Case Management: The treatment plan was the extraction of teeth 14, 24, 34; alignment with pre-adjusted McLaughlin Bennett Trevisi (MBT) 0.022; retraction of the anterior segment with a T-loop, TPA, and close spacing of the missing first molar with couple force on the buccal and lingual side and tip back. Retention was done with removable retainers. At the end of the treatment, normal incisive inclination and closed space of the missing first molar were achieved, along with an improvement of the facial profile. Conclusion: Bimaxillary protrusion can be successfully treated by means of extraction of the premolar(s), space closure for correction of the profile with T-loop and TPA, and closing the space of the missing molar with couple force on the buccal and lingual sides and tip back.

“…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.

Background/Purpose: Orthodontically induced apical root resorption is an inescapable consequence of fixed orthodontics. This root resorption causes post-orthodontic complications in some treated cases. To avoid these complications proper diagnosis of the site and amount of resorption is important. The aim of this study was to compare the diagnostic ability of Orthopantomogram (OPG) and Cone Beam Computed Tomography (CBCT) in detecting apical root resorption after en-masse retraction of maxillary anterior teeth in a sample of Saudi Arabian population.Materials and methods: The study sample comprised of 30 patients diagnosed with bimaxillary dentoalveolar protrusion. The treatment plan involved extraction of all first premolars followed by en-masse retraction of the anterior teeth. OPG images were obtained at the beginning of treatment and after the end of the retraction phase and a CBCT image were also obtained for the same patient at the same centre other than orthodontic reason like implant placement, temporomandibular joint (TMJ) problems, sleep apnea, etc. after orthodontic treatment completion. The scoring system of Levander and Malmgren was used to assess the degree and severity of root resorption in the maxillary incisors. Dalhbergs error and coefficient of reliability (ICC) were used to calculate the correlation between the two sets of readings. Pearson chi-square test was used to compare the difference in root resorption between OPG and CBCT images. A P-value of <0.05 was considered to be statistically significant.Results: No resorption was observed in 39.2% and 16.6% of incisors with OPG and CBCT respectively. Mild resorption was observed in 50% and 66.7% of incisors with OPG and CBCT respectively. Moderate resorption was found in 10% and 15% of incisors with OPG and CBCT respectively. Severe root resorption was found in 0.8% and 1.7% of incisors with OPG and CBCT respectively. Statistically, significant differences were found in both methods of evaluation in all grades of root resorption for all the maxillary incisors (P<0.05).Conclusion: OPG had consistently underestimated the amount of orthodontically induced apical root resorption when compared to CBCT. OPG is only useful for the primary evaluation of root resorption. CBCT can be used as an adjunct diagnostic tool on a case-to-case basis in patients with moderate to severe root resorption to manage post-orthodontic treatment complications.
