Abstract Background: The occurrence of gingival recessions (GR) after orthodontic treatment (OT) is well described in the literature. However, there is a lack of information about changes to pre-existing GR during OT. Methods: The aim of this retrospective study was to examine the change of GR before and after OT. Intraoral photographs of 993 patients treated with fixed appliances between 2005 and 2017 were evaluated. Patients who had at least one GR on the vestibular surface of maxillary/mandibular teeth mesial to first molars were included. GR was measured on good quality plaster models before and after OT. The change of GR (T0-T1) was categorised into the three groups: worsened, did not change and improved (this group consisted of GR, which became better but did not disappear, and fully healed, which disappeared after OT)). The change of GR by ≥0.5 mm was recorded. Statistical analysis was performed using SPSS Statistics (Version 22.0. Armonk, NY). Results: Fifty-one (5.1%) patient had ≥1 GR before OT. Of them, 37 (72.5%) patients were included in the final analysis according to the inclusion criteria. GR before OT was found on 114 buccal/labial surfaces. The mean GR improvement was 0.51 (95% CI: 0.40, 0.63) mm (p<0.001). GR improved in 71 teeth (62.3%), did not change in 37 (32.4%), and worsened in 6 (5.3%). Of the 71 GR, which improved, full healing was observed in 15 (21.1%) teeth. GR had a greater chance of improvement in cases with a thick/normal gingival biotype compared with the thin biotype (OR 2.4; 95% CI: 1.07; 5.28) (p=0.03). There was a lower chance for GR improvement in cases with pre-treatment open bite (OR 3.29; 95% CI: 1.10; 9.81) (p=0.03) and Class III patients (OR 2.79; 95% CI: 1.14; 6.83) (p=0.03). Conclusions: Based on the results of this retrospective study, we conclude that orthodontic treatment may change and even influence the healing of GR.

Objective: To analyze the prevalence of malocclusion and occlusal characteristics in referred Nepalese orthodontic patients with respect to age, gender, Angle’s classification. Materials & Method: Study models of 464 orthodontic patients (165 male and 299 female) of the age ranging from 11 to 30 years were studied to evaluate the prevalence of malocclusion using Angle’s classification and occlusal characteristics of overjet, overbite, open bite, cross bite, displacement, and hypodontia according to the method of Dental Health Component of Index of Orthodontic Treatment Need. The association between DHC grades and Angle’s classification and gender were assessed using chi-square test (p < 0.01). Result: The malocclusion status among the Nepalese seeking orthodontic treatment was 54.7% Class I, 36.9% Class II, and 8.4% Class III. The occurrence of occlusal discrepancies were overjet in 43.8%, increased overbite in 20.7%, open bite in 8.2%, cross bite in 23.3%, displacement in 65.7% and hypodontia in 11.3%. Conclusion: 16.2 % required no/little treatment need, 20.4% required borderline treatment need, and 63.4 % required great/severe treatment need according to DHC scale. There was statistically significant association between DHC grades and distribution of malocclusion and gender of the Nepalese subjects.

Aim: To evaluate the periodontal status before and after orthodontic treatment and to analyze the confounding factors associated with it. Materials and Methods: The present retrospective study analyzed pre- and posttreatment records of a total of 60 patients. Intraoral digital photographs before and after the orthodontic treatment were used to measure the following three periodontal variables: (a) width of the keratinized gingiva, (b) gingival recession, and (c) the status of interdental papilla. The ImageJ 46 software imaging program was used to perform the required measurements. The clinical data were then analyzed in an association with the participants’ demographic data, the type of orthodontic tooth movement, and other confounding factors. The data obtained were manually entered into the statistical package and analyzed using a significance level set at P < .05. Descriptive statistics, paired t-tests, and Pearson’s correlation analysis were used to identify differences among the studied variables. Results: Among the 60 patients, the majority (66.7%) were females. Most cases of the treated malocclusion were Class II, and most patients underwent intrusion and retrusion movements. The width of keratinized gingiva increased for most sites of upper teeth. In contrast, the lower teeth showed a mix of improvement and compromised width of keratinized gingiva. As a measure of gingival recession, the difference of clinical crown height revealed the tendency toward a reduced clinical crown height for most sites. Upper left lateral incisors and canines showed significant values with regard to keratinized gingival width measurements and tooth movements such as extrusion and intrusion movements. Likewise, with regard to the clinical crown height, upper right central incisors showed significant differences when correlated with the interincisal angle, lower incisors to the mandibular plane, and upper incisors to the NA line. The upper lateral incisors also showed significant correlations to certain cephalometric measurements. Conclusions: The orthodontic treatment was found to exert a significantly positive impact on the surrounding periodontium, particularly in the upper canine areas. Likewise, various types of tooth movement were found to positively affect the periodontium.

Background: Hypodontia is one of the most common anomalies in dentistry. Hypodontia has a negative impact on oral health-related quality of life with patients best seen in a multidisciplinary clinic to improve treatment outcomes. Aim: To investigate the prevalence of hypodontia and its association with other dental anomalies, as well as malocclusion, and to investigate the treatment planned for patients attending the clinic and whether the type of missing teeth affected the proposed treatment. Materials and Methods: Analysis of consecutive patients attending the hypodontia clinic at a dental hospital between February and November 2020. A total of 100 patients who met the inclusion criteria were identified. Data collected included the following: age/sex; number and type of missing teeth; pre-treatment occlusion; presence of other dental anomalies; and planned treatment. Results: A total of 100 patients (55% female; age range = 7–41 years; mean age = 18 years) were included. Of the cohort, 47% had a class I skeletal relationship and participants were significantly less likely to have a class III skeletal or incisor relationship; 45% had another dental anomaly with the most common being microdontia. Space opening was the preferred treatment option for those managed by orthodontic treatment with resin-bonded bridges most likely to be used for restoration of spaces, 86%. Conclusion: Lower second premolars were the most commonly missing teeth. Participants were significantly less likely to have a class III incisor or skeletal relationship than class I or II. Space opening was the favoured approach for orthodontic treatment, particularly for maxillary lateral incisors.

Crossbite is one of the most prevalent malocclusion, posterior crossbite occurs in 8% to 22% of orthodontic cases and anterior crossbite has been seen in Class III cases, which accounts for 3.4% of orthodontic cases. The etiology of posterior crossbite can include any combination of dental, skeletal, and neuro muscular functional components, but the most frequent cause is reduction in width of the maxillary dental arch. Patients/cases seeking comprehensive orthodontic treatment in between 5 to 35 years were diagnosed for crossbite with diagnostic model and care record file. Out of 300 cases 163(54.3%) had crossbite, 90(30%) had anterior crossbite and 109(36.3%) had posterior cross bite. Among posterior crossbite 60(20%) had unilateral and 49(16.3%) had bilateral crossbite. Posterior crossbite was more prevalent than anterior crossbite. Cases with Class I molar relation showed more crossbite. Crossbite was more prevalent in cases with congenitally missing teeth.Bangladesh J Medicine Jan 2015; 26 (1) : 9-12

ABSTRACT Objectives The objectives were to evaluate and compare the presence of bone dehiscence before and after orthognathic surgery. Materials and Methods In this retrospective study, 90 cone-beam computed tomography (CBCT) scans from 45 patients were evaluated. Class II (n = 23) and Class III (n = 22) orthodontic patients who were being prepared for orthognathic surgery were measured. CBCT scans were obtained about 30 days prior to (T0) and 6 months after (T1) double jaw orthognathic surgery. The distance between the cemento-enamel junction (CEJ) and the alveolar bone crest was assessed at the buccal and lingual surfaces of all teeth, on both sides and arches, except for the second premolars and the second and third molars. A total of 1332 sites were measured for Class II (644) and Class III (688) patients. The software used was OsiriX (version 3.3 32-bit). Data were compared with Wilcoxon and McNemar tests at the 5% level. Results Bone dehiscence before surgery was present in 26% and 15% of the Class II and III groups, respectively. The presence of dehiscence increased to 31% in the Class II and 20% in the Class III patients after surgery (P &lt; .05). Conclusions The prevalence of dehiscence increased slightly in Class II and Class III surgical-orthodontic patients after orthognathic surgery. Temporary vascular supply reduction and oral hygiene difficulties may explain these results; however, more studies are needed.
