Abstract Objective: To assess the frequency of maxillary ectopic canine both buccally and palatally displaced with incisor root resorption and dental agenesis. Methods: The cross-sectional study was conducted from April 8 to June 29, 2019, at the Department of Orthodontics, Dr. Ishrat Ul Ebad Khan Institute Of Oral Health Sciences, and Dow Dental College, Dow University Of Health Sciences, Karachi, and comprised orthodontic patients diagnosed with maxillary ectopic canine eruption. Root resorption and agenesis were diagnosed on panoramic films. Root resorption was further confirmed by periapical radiographs. Data was analysed using SPSS 21. Results: Of the 98 subjects, 86(87.8%) had buccally displaced canines of which 38(44.2%) were associated with root resorption, while 12(12.2%) patients had palatally displaced canines of which 10(83.3%) had root resorption (p=0.011). Overall, 30(30.6%) lateral incisors were resorbed, 7(7.1%) both central and lateral incisors, 5(5.1%) premolars, and 6(6.1%) both lateral incisors and premolars were resorbed. Agenesis was detected in 10 (10.2%) subjects (p=0.62). Conclusion: There was found to be no association of maxillary ectopic canines with incisor root resorption and dental agenesis. Key Words: Root resorption, Agenesis, Ectopic canine, Buccally displaced canine, Palatally displaced canine.
The aim of the study is to evaluate and compare the soft tissue chin thickness values among adult patients with different vertical growth patterns. A sample size of 180 adults patients (32 males and 148 females), with an average age of 21.42 years (range 17-32 years), was selected. The sample was divided into three groups according to the vertical growth pattern using SNMP angle (hypodivergent <27°, normodivergent 27-37° and hyperdivergent >37°). The soft tissue chin thicknesses in each group were measured at pogonion (Pog), gnathion (Gn), and menton (Me) and analyzed using the one-way analysis of variance and post-hoc Tukey test. The soft tissue chin thickness values were greater in hypodivergent group at Pog (12.71±2.10 mm), Gn (9.72 ± 2.55 mm) and Me (9.13 ± 2.88 mm) and smallest in hyperdivergent group (Pog 8.05 ±1.20 mm, Gn 6.07±1.47 mm, Me 5.91±1.21 mm). The soft tissue chin thicknesses were greater in men than women. Soft tissue chin thickness was greater in hypodivergent adults than those of normodivergent and hyperdivergent adults. In all the three groups, soft tissue thickness values were greater in men than women.
OBJECTIVE: The vast spread of COVID-19 not only affected the major businesses of the world but also the health care facilities like dentistry. Due to the unprecedented closure of dental services, on-going orthodontic patients also suffered the brunt. The aim of this study was to assess the at-home management approaches used by the patients to tackle the complications associated with orthodontic treatment. METHODOLOGY: It was a cross-sectional questionnaire-based study carried out from June 15 to September 15, 2020 in orthodontic OPD of Jinnah Medical and Dental College, Karachi. A total of 300 orthodontic patients, 208 females and 92 males between ages from 15 to 35 years completed a questionnaire on the complications faced by them and management techniques adopted by them during COVID-19 related office closures. Convenient sampling method was used for data collection. RESULTS: The majority of patients reported in this study were females. Approximately 69.33% (n = 300) of the responders were females and 31% were males. The highest numbers of complications reported during the lockdown period were loose brackets, loose bands and poking of archwire. The most common at-home hack used was removing the loose bracket/ bands and cutting of free end of arch wire with nail cutter like instrument. CONCLUSION: It is the responsibility of the clinician to keep in touch with their patients during pandemic like situation through telemedicine portal. In case of emergencies, patients should be provided with an adequate amount of information to tackle any complications with ease and without hurting themselves.
