“…This study is also perfectly balanced with both sides of impacted canines. The difference between these two studies [17][18] Gender-wise canine impaction is also narrated in a number of studies and most of them suggest the more prevalence in females due to the diminution of facial bones and jaws which lead to more impaction of canine. However, the large number of female involved in the study suggest a drift of more female having orthodontic therapies.…”

Background: Maxillary canines are considered as the keystone of mouth. It plays main role in supporting the upper lip and biting and tearing of food. Canines are also called as cuspids, the upper one is second most common teeth. The purpose of this research was to find the pattern and prevalence of the maxillary canine. Study design: It is a retrospective study conducted for the duration of six months from April 2022 to September 2022 at the dental department of Karachi Medical and Dental College, Karachi. Material and Methods: The study was conducted on 200 subjects visited the dental sciences department of the hospital. The patients who willingly participated in the study was included. The CBCT data was collected and sorted for the further use. Results: Out of the 200 subjects, the 96 (48%) males and 104 were females. The left buccal quadrant of impaction was observed in the 21 males and 15 females. The 5 male and 10 female subjects have the both buccal impaction position. The 8 male and 10 female have the both platal position of impaction. The prevalence of subtype l was 55% in the female and 44% in the males. The subtype II was observed in the 44% females and 55% males. There was no case of type IV subtype. The type VII prevalence was also higher in female 66% as compared to males 33%. Conclusion: The maxillary canine impaction is higher in the female as compared to the males. The impaction prevalence is most commonly observed on the left side as compared to the right side. It was also observed that the buccal and palatal impaction are predominant than other impactions. Keywords: cuspids, maxillary canine, palatal impaction

“…In the general population, the frequency of root dilaceration varies in different ethnic groups, between 0.3 and 27.2%, with no gender predilection. (Cao et al, 2021; Nabavizadeh et al, 2013; Sultan, 2015; Topouzelis et al, 2010; Weckwerth et al, 2016). However, in patients with NSOC, the prevalence ranged from 7.5% to 31.2% in CL; 6–29.6% in CLP and 8.3–26.3% in CP.…”

“…In anterior teeth, dilaceration can be related to trauma during tooth development (intrusion or avulsion of the deciduous tooth) and to the presence of OC, with involvement of the alveolar bone, in which there is not adequate space for tooth development (Weckwerth et al, 2016). In posterior teeth, the etiological factors involved are ankylosis of a primary tooth (premolar teeth), heredity; supernumerary teeth; insufficient space for dental development; interference of anatomical repairs (nasal fossa, mandibular canal, and maxillary sinus cortical bone), (Cao et al, 2021; Topouzelis et al, 2010) ectopic tooth germ development (Malcić et al, 2006), or even the presence of a dentigerous cyst or a compound odontoma (Nabavizadeh et al, 2013). Another hypothesis that could explain this change is related to the bone remodeling gradient (plasticity gradient) (Standerwick, 2014) that could be the cause of a tooth root displacement (Fuentes et al, 2018).…”

“…The large differences between the findings on the prevalence of root dilaceration, in the various populations studied, may be due to the different ethnic groups evaluated in the different studies and due to the methodological criteria established by each of the researchers (Akcam et al, 2010; Al Jamal et al, 2010). As for the clinical aspect, dilaceration is of great importance for orthodontics, as dilacerated roots are difficult to move orthodontically; have greater risk of impaction; external resorption and also prevent the favorable insertion of mini implants (Cao et al, 2021). Knowledge of the presence of root dilacerations is essential for surgical planning of extractions, especially in lower third molars (Weckwerth et al, 2016).…”

Dental anomalies in non‐syndromic orofacial clefts: A clinical approach

et al. 2022

View full text Add to dashboard Cite

Orofacial clefts (OC) represent some of the most common congenital malformations and affect multiple structures in the craniofacial region. There are a wide range of morphological OC types within the spectrum of both non‐syndromic OC (NSOC) and syndromic OC, including cleft lip (CL), cleft lip and palate, (CLP), and cleft palate (CP). Here, we describe the most frequent dental anomalies seen in the permanent dentition of individuals with NSOC, comparing them between the three main cleft types (CL, CLP, and CP). We present these findings from the perspective of prevalence relating to each anomaly, as well as the clinical characteristics and potential impact on the rehabilitation process. The investigation of dental anomalies associated with NSOC is important, helping to expand the phenotypic characterization of NSOC, improve the initial diagnostics, and establish appropriate rehabilitation and counseling.

“…2 The position of the bend or curve can make it difficult for the tooth to be moved and presents a high risk of complications related to root resorption, bony fenestration, and perforation of a cortical plate. 1,3,4 The majority of the current research has defined dilaceration as an angle of 90° or more affecting the long axis of the tooth while some studies have considered root deviation greater than 20° constitutes dilaceration. 5 Due to the unusual crown-root morphology, root dilaceration has been further considered as the most common cause of impaction of maxillary central incisors in children and adolescents.…”

The clinical management of impacted incisors affected by root dilaceration is challenging. This case report presents the treatment of an adolescent female patient who presented with a deeply impacted, rotated and dilacerated maxillary central incisor and also reviews the current literature on the definition, prevalence, aetiology, diagnosis, and treatment of the anomaly. The impacted and dilacerated incisor was successfully orthodontically treated following a two-stage surgical exposure and after being rotated 100 degrees in the sagittal plane (due to the deep impaction and severe displacement). A Ballista spring and piggyback appliance technique were used to elevate the tooth. The dilacerated incisor was successfully preserved and relocated in the dental arch. The pre-operative and post-operative CBCT scans showed no significant root resorption of the repositioned tooth.
