ABSTRACTObjective: The aim of this study was to document the prevalence of hypodontia in the permanent dentition among a group of Turkish sample who sought orthodontic treatment and to compare present results with the specific findings of other populations. The occurrence was evaluated in relation to gender, specific missing teeth, the location and pattern of distribution in the maxillary and mandibular arches and right and left sides.Materials And Methods: Orthodontic files of 2413 patients (1557 females-mean age: 17.78±5.41 years old and 856 males-mean age:17.02±5.47 years old) which included orthopantomograms, study models, and anamnestic data were examined for evidence of hypodontia.Results: The prevalence of hypodontia was 7.54% (8.09% for female and 6.54% for male). Hypodontia was found considerably more frequently in the maxilla than in the mandible. Similarity in the distribution of missing teeth between the right and left sides was detected. The most frequently missing teeth were the maxillary lateral incisors, followed by the mandibular and maxillary second premolars. The majority of patients had one or two teeth missing, but seldom three or more.Conclusions: Present data for hypodontia were within the wide range reported in the literature. The findings of patients with hypodontia involving the anterior teeth and others missing more than two teeth in the same quadrant were an indication of a great need for orthodontic treatment. By early detection of missing teeth, alternative treatment modalities can be planned and performed with a multidisciplinary team approach. (Eur J Dent 2007;1:167-173)

Fractured and missing teeth within the aesthetic zone have always posed a clinical challenge for the dental team. Management and treatment requires the input from a number of dental specialists to guarantee a high quality result. A case report is presented to demonstrate an effective combined orthodontic/restorative approach that fully restored aesthetics and function. The report is of a 14-year-old girl who traumatized her maxillary central incisors, in a dentition that was already compromised as she had congenital absence of her maxillary left lateral incisor. Using fixed orthodontic appliances, the fractured teeth were extruded to bring the fracture line above the level of the alveolar bone. This movement allowed an immediate aesthetic improvement, using stainless steel prefabricated posts and composite resin buildups, which also facilitated further orthodontic tooth movement. Teeth, that would otherwise have been extracted, were salvaged and, utilizing a multidisciplinary team approach, a reasonable long-term prognosis has resulted. CPD/Clinical Relevance: This case report aims to demonstrate how a multidisciplinary team approach in Orthodontics can be utilized for management of severely handicapped dentitions that have sustained dental injury. It is not the aim of this case report to discuss the treatment of dental injuries but to demonstrate and provide an overview of the possible treatment modalities that can be effective in restoring function and aesthetics, with special consideration given to missing teeth and subgingival crown fractures within the aesthetic zone.

Abstract Objective To compare the accuracy of complete-arch scans and quadrant scans obtained using a direct chairside intraoral scanner. Material and methods Intraoral scans were obtained from 20 adults without missing teeth except for the third molar. Maxillary and mandibular complete-arch scans were carried out, and 4 quadrant scans for each arch were performed to obtain right posterior, right anterior, left anterior, and left posterior quadrant scans. Complete-arch scans and quadrant scans were compared with corresponding model scans using best-fit surface-based registration. Shell/shell deviations were computed for complete-arch scans and quadrant scans and compared between the complete-arch scans and each quadrant scans. In addition, shell/shell deviations were calculated also for each individual tooth in complete-arch scans to evaluate factors which influence the accuracy of intraoral scans. Results Complete-arch scans showed relatively greater errors (0.09 ~ 0.10 mm) when compared to quadrant scans (0.05 ~ 0.06 mm). The errors were greater in the maxillary scans than in the mandibular scans. The evaluation of errors for each tooth showed that the errors were greater in posterior teeth than in anterior teeth. Comparing the right and left errors, the right side posterior teeth showed a more substantial variance than the left side in the mandibular scans. Conclusion The scanning accuracy has a difference between complete-arch scanning and quadrant scanning, particularly in the posterior teeth. Careful consideration is needed to avoid scanning inaccuracy for maxillary or mandibular complete-arch, particularly in the posterior area because a complete-arch scan might have potential error than a quadrant scan.

ABSTRACT The aim of this study investigates mesiodistal crown size of the maxillary and mandibular incisors of patients with palatally impacted canines (PDC). Pretreatment dental casts of orthodontic patients with PDC of one or both maxillary canines (N: 33) were collected. This PDC sample was matched according to age and sex with pretreatment dental casts from unaffected orthodontic patients. For the PDC and matched control samples, maximum mesiodistal crown diameters were recorded for the four incisors on the right side only. The results showed that, on average, the mesiodistal crown diameters for the maxillary and mandibular incisors measured smaller in the PDC sample than in the control sample. These findings of statistically significant tooth-size reductions associated with PDC occurrence indicate a generalized pattern of reduced tooth size as a characteristic associated with the PDC anomaly. Further, the presence of generalized tooth-size reduction in cases with palatally displaced canines help explain why most orthodontic treatment plans for PDC patients are of the nonextraction type.

Two cases are presented where the odontomas had caused the impaction of the anterior teeth and required a combined surgical and orthodontic treatment to bring these teeth into the arch. In the first case a large a complex odontome had caused the impaction of the right central incisor, lateral incisor and canine. In the second case a compound odontome blocked the eruption pathway of the right central incisor. It is emphasised that radiographic examination of all pediatric patients that present clinical evidence of delayed permanent tooth eruption or temporary tooth displacement with or without a history of previous dental trauma should be performed. Early diagnosis of odontomas allows adoption of a less complex and less expensive treatment and ensures a better prognosis.

Summary Background and objectives The results from the literature regarding the influence of supplemental vibrational forces (SVFs) on orthodontic treatment are controversial. Therefore, this systematic review aimed to evaluate whether SVFs have positive effects, such as in accelerating tooth movement, alleviating pain, and preventing root resorption, in orthodontic patients. Search methods Searches through five electronic databases (PubMed, MEDLINE, EMBASE, Web of Science, and Cochrane Central) were complemented by hand searches up to January, 2019. Selection criteria Randomized controlled trials and controlled clinical trials reporting on the effects of SVFs in orthodontic patients in English were included. Data collection and analysis Study selection, data extraction, and a risk of bias assessment were independently performed by two reviewers. Study characteristics and outcomes were reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. A qualitative analysis of the effects of SVFs on orthodontic tooth movement, pain experience, and root resorption was conducted. Results Thirteen studies, including nine clinical trials, were eligible for inclusion in the systematic review. There was no significant evidence to support the positive effects of SVFs in orthodontic patients, neither in accelerating tooth movement nor in alleviating pain experience. According to the Grading of Recommendations Assessment, Development and Evaluation (GRADE) criteria, the quality of the evidence was very low for all the outcomes in the qualitative analysis. Limitations The results of this systematic review are based on a limited number of studies and the methodological heterogeneity and non-comparability of original outcomes made it difficult to conduct a meta-analysis. Conclusions There is insufficient evidence to support the claim that SVFs have positive clinical advantages in the alignment of the anterior teeth. The potential positive effects of vibrational forces on space closure, pain experience, and root resorption in orthodontic patients are inconclusive with no sufficient information at present. High-quality clinical trials with larger sample sizes are needed to find more comprehensive evidence of the potential positive effects of vibrational forces. Registration The protocol for this systematic review was registered on PROSPERO (CRD42018098788). Funding This study has not received any contributions from private or public funding agencies. Conflict of Interest None.

Introduction: The objective of this study was to determine the prevalence and the pattern of hypodontia among orthodontic patients in Klinik Pergigian Jalan Sultan Mahmud, Kuala Terengganu. Materials and Methods: A retrospective of 351 orthodontic patients record review study was conducted; comprised of 104 males and 247 females. The records were reviewed by trained dental officer between October 2016 and June 2017. The Chi-square and Fisher's Exact Tests were carried out for statistical analysis. Results: The prevalence of hypodontia was 10.8%. Thirty-eight patients were found to have at least single missing tooth. A significant difference was found between males and females of having hypodontia (p = 0.048). No significant difference was found for hypodontia patients by races (p = 0.829). The maxillary lateral incisor was the most frequently missing tooth followed by mandibular second premolars and mandibular lateral incisors. Hypodontia cases observed tended to be more likely occurred in the upper left arch compared to the lower arch. The majority of hypodontia patients had single missing tooth, but rarely more than 3 missing teeth. Hypodontia patients had mainly Class III malocclusion, however no statistically significant was found (p= 0.081). Conclusion(s): The prevalence of hypodontia of this study was within the range of what is being reported in the literature and showed gender significant. Hypodontia was mainly involved maxillary lateral incisors; more prevalent in the upper arch; and mostly observed in patients with Class III malocclusion in the study sample. Early detection and accurate diagnosis are essential. Therefore, alternative treatment modalities can be well planned under multidisciplinary team approach in restoring the aesthetic and function.

Abstract: A Glandular Odontogenic Cyst (GOC) is a rare developmental cyst of odontogenic origin. Occurrence rate is low, with less than 150 cases reported in the literature thus far. 1 GOCs can be misdiagnosed due to clinicopathological similarities to other odontogenic cysts, including those of a benign and malignant nature. A wide range of ages can be affected, with a mean age of 45.7. 2 The most commonly affected site appears to be the anterior mandible. An unusual presentation of a GOC affecting the right posterior mandible of a 42-year-old male is reported. CPD/Clinical Relevance: This article highlights the importance of appropriate special investigations for a glandular odontogenic keratocyst and treatment modalities.

Treatment of severe occlusal cant requires a combination of fixed orthodontic treatment with orthognathic surgery. This case report was aimed to describe the combined fixed orthodontic treatment of Le Fort 1 in maxillary occlusal cant of class III dentoskeletal malocclusion with facial asymmetry. Case report: A female patient aged 17 years seven months came to the private clinic, complained of oblique maxillary teeth, and the right posterior was unable to masticate comfortably. The patient wants to be treated for her teeth and jaw. Extraoral examination revealed facial asymmetry, sunken profile and slightly protruding chin. The intraoral examination resulted in the maxillary median line that shifted to the left, mandible shifted to the right, anterior crossbite, unilateral posterior crossbite, and retrusion of maxillary and mandibular anterior teeth. The lateral cephalometric analysis resulted in class III dentoskeletal malocclusion. The diagnosis was class III dentoskeletal malocclusion with maxillary occlusal cant, facial asymmetry, anterior crossbite, and posterior unilateral crossbite. The treatment plan was fixed orthodontic treatment combined with Le Fort orthognathic surgery. The treatment was carried out in 4 stages: decompensated orthodontic treatment, maxillary orthodontic treatment, post-orthognathic surgery orthodontic treatment, debonding, and retainer placement. Conclusion: Class III skeletal malocclusion with maxillary occlusal cant, facial asymmetry, anterior crossbite, and the unilateral posterior crossbite was successfully treated with a fixed orthodontic appliance and Le Fort 1 orthognathic surgery. The dental and skeletal relations were achieved for class I, the interdigitation of the maxillary and mandibular teeth was locked, the masticatory function was corrected, and the patient was very satisfied with her facial aesthetics.Keywords: Class III skeletal malocclusion, facial asymmetry, maxillary cant, anterior crossbite, unilateral posterior crossbite, orthognathic surgery.

ABSTRACT General dentists play an important role in intercepting the progression of malocclusion. The right stage of referral to specialist orthodontist is considered key to the success of orthodontic treatment. The objective of this study was to assess the preparedness of fresh dental graduates in dealing with orthodontic patients in general dental practice. A total of 80 general dentists who had recently completed the BDS program formed the study group. They were asked to respond to a self-administered questionnaire consisting of case scenarios to evaluate their knowledge of Angles classification, occlusal characteristics, the ideal stage of treatment and need for referral to specialist orthodontist. The response rate was 75% (n = 60). 87% (n = 52) correctly identified the Angles Classification of the presented cases. 87% (n = 52) and 100% (n = 60) correctly identified overbite and over-jet cases. Cross bite and deviated midline was correctly identified by 68% (n = 41) and 65% (n = 39) of the respondents respectively while 93% (n = 56) diagnosed median diastema correctly. Almost all the respondents (97%) identified the cases which have to be referred to the orthodontist while, more than half (55%) did not know the ideal time to initiate orthodontic treatment. The graduates recognized their limits of personal competence and successfully identified the cases that need to be referred to the orthodontist. Proper emphasis should be placed on the ‘the ideal time of referral and initiation of treatment’ during undergraduate orthodontic training. How to cite this article AlShahrani I.
