A case report of cleidocranial dysplasia: A noninvasive approach

Ayub NAFM, Hamzah SH, Hussein AS, Rajali A, Ahmad MS

Spec Care Dentist, 2021 Jan;41(1):111-117.

Cleidocranial dysplasia (CCD) is a rare bone disorder. The main dental features are the presence of multiple retained deciduous teeth and supernumerary teeth, as well as unerupted permanent teeth. To date, CCD is managed by a combination approach, which consists of the extraction of deciduous and supernumerary teeth, followed by orthodontic traction of unerupted permanent teeth. This case highlights the management of a girl with CCD, who refused the recommended protocol. A 15-year-old Malay female presented with a complaint of retained deciduous teeth. Intraoral examination revealed multiple retained deciduous teeth. Radiographs showed numerous impacted supernumerary and unerupted permanent teeth. The patient opted to improve her facial appearance with a less aggressive treatment option. A composite build-up on all anterior maxillary deciduous teeth was carried out until the patient was ready to undergo surgical intervention.

Salvaging a Periodontally Compromised and Endodontically Involved Three-Rooted Mandibular First Molar With Cervical Enamel Projection

Western JS, Gupta VV, Ramachandra SS

Compend Contin Educ Dent, 2019 Mar;40(3):172-177.

PMID: 30829499

This case report describes the management of a mandibular first molar with an additional distolingual root (radix entomolaris) and grade III cervical enamel projection through a multidisciplinary approach. Diagnosis for the case was endodontic-periodontal lesion due to non-vitality and associated advanced periodontal destruction. The patient was treated with drainage of the periodontal abscess with adjunct antibiotics, phase I periodontal therapy, endodontic therapy, radiculoplasty, regenerative periodontal therapy, replacement of the missing right mandibular second molar, and long-term maintenance. Follow-up of the patient up to 9 months has been uneventful. Cases of advanced periodontal destruction typically show some degree of tooth mobility, which was absent in this case. The article discusses the tripod effect as well as the increased surface area for periodontal attachment provided by the additional root contributing to the non-mobility of the involved tooth.

Talon cusp in Malaysia

Rusmah, Meon

Aust Dent J, 1991 Feb;36(1):11-4.

PMID: 2029226

Five hundred and thirty-six patients were examined for the presence of talon cusps. The anomaly was observed in 28 patients (5.2 per cent). There was no sex predilection in the occurrence. Only two patients had a bilateral occurrence, with the maxillary lateral incisors being the most commonly affected. Radiographic evidence of pulpal extension into the cusp was observed in five patients. Many of the affected teeth presented with deep developmental grooves some of which were carious and/or occlusal interference leading to malocclusion.

Unusual Dental Morphology in a Chimpanzee: A Case Report Utilizing Cone-Beam Computed Tomography

Al-Amery SM, Nambiar P, John J, Purmal K, Ngeow WC, Mohamed NH, et al.

J Vet Dent, 2018 Jun;35(2):96-102.

PMID: 29865987 DOI: 10.1177/0898756418776448

This case report illustrates the teeth morphology of a chimpanzee and its anatomical variations. A well-preserved skull of a male Pan troglodytes troglodyte chimpanzee was scanned using a cone-beam computed tomography machine. Measurements included tooth and crown height, root length, root canal length and width (posterior teeth), and pulp cavity length (anterior teeth). Nonmetrical parameters included number of canals and foramina per root of every root. Interestingly, the mandibular central incisor was longer than the lateral incisor, and all the mandibular anterior teeth presented with a solitary flame-shaped or conical-calcified structure in their pulp cavity. The premolars are usually dual rooted except for the first maxillary premolar that displayed 3 roots. Other unusual discoveries were the presence of bilateral radicular dens invaginatus in the mandibular first premolars and the possibility of having 2 canals and 2 foramina in the roots of the posterior teeth. The presence of conical stone mineralizations at the pulp cavity and the presence of dens invaginatus were of particular interest.

Fulltext Supernumerary tooth: report of a case

Fazliah, S.N.

Archives of Orofacial Sciences, 2007;2(1):54-58.

MyJurnal

Supernumerary tooth (ST) is a developmental anomaly and has been argued to arise from multiple etiologies. These teeth may remain embedded in the alveolar bone or can erupt into the oral cavity. When it remains embedded, it may cause disturbance to the developing teeth. The erupted supernumerary tooth might cause aesthetic and/or functional problems especially if it is situated in the maxillary anterior region. A case of supernumerary teeth is presented where the teeth have been left in place and which later gave rise to some problems. The patient had history of trauma and requested orthodontic treatment for the misalignment of his anterior teeth. The treatment options are further discussed.

Dental anomalies affecting the teeth are relatively common. Simultaneous occurrence of multiple dental abnormalities in a single tooth is uncommon and relatively rare. One such abnormality routinely encountered in dental clinics is the talon cusp. It is also referred to as dens evaginatus, characterized by the presence of an accessory cusp-like structure projecting from the cingulum of anterior teeth. It has an increased predilection for maxillary teeth and permanent dentition. Although numerous cases of talon cusp have been reported in the literature, occurrence of multiple talon cusps in maxillary central incisors has not been found in the literature. This case report highlights the presence of talon cusps in maxillary anterior teeth with multiple impacted supernumerary teeth.

Zaman JQ, Yahaya N, Razali M, Ibrahim N, Nor GM, Ramli R

Singapore Dent J, 2007 Dec;29(1):41-5.

PMID: 18472529

Obstruction remains as an important cause of failure in the eruption of a tooth. In this article, a 15-year-old girl was presented with retained upper left primary canine (63) and first primary molar (64), while the contralateral permanent canine (13) and premolars (14 and 15) have erupted. Upon radiographic examination, a mass which was diagnosed later to be compound odontome was detected. The treatment consisted of surgical removal of the odontome, extraction of the primary canine (63) and left permanent canine (23), and transplantation of the permanent canine (23). The management of this case and the literature related to autotransplantation are discussed.

Fulltext Prevalence of Third Molar Agenesis: Associated Dental Anomalies in Non-Syndromic 5923 Patients

Sujon MK, Alam MK, Rahman SA

PLoS One, 2016;11(8):e0162070.

PMID: 27580050 DOI: 10.1371/journal.pone.0162070

The aim of this study was to investigate the prevalence of third molar agenesis and other associated dental anomalies in Bangladeshi population and to investigate the relationship of other dental anomalies with the third molar presence/agenesis. A retrospective study was performed using panoramic radiographs of 5923 patients, who ranged in age from 10 to 50 years. All radiographs were analyzed by Planmeca Romexis® 3.0 software (Planmeca Oy, Helsinki, Finland). Pearson chi-square and one way ANOVA (Post Hoc) test were conducted. The prevalence of third molar agenesis was 38.4%. The frequency of third molar agenesis was significantly higher in females than males (p <0.025). Third molar agenesis was significantly more prevalent in maxilla as compared to mandible (p <0.007). The prevalence of other dental anomalies was 6.5%, among them hypodontia was 3.1%. Prevalence of third molar agenesis varies in different geographic region. Among the other dental anomalies hypodontia was more prevalent.

Fulltext Dental anomalies and their treatment modalities/planning in orthodontic patients

Roslan AA, Rahman NA, Alam MK

J Orthod Sci, 2018;7:16.

PMID: 30271761 DOI: 10.4103/jos.JOS_37_18

OBJECTIVE: This study was carried to study the prevalence of dental anomalies and treatment modalities/planning among the orthodontic patients.

MATERIALS AND METHODS: A total of 370 orthodontic records including their pre-treatment orthopantomographs (OPG) and study models of orthodontic patients in permanent dentition who attended dental clinic were assessed for impaction, hypodontia, supernumerary, supraocclusion, infraocclusion, and any other anomalies excluding the third molars. The association of anomalies with gender status and racial status was analyzed using Pearson's Chi-square test. A P value of <0.05 is considered as significant. The confidence interval at 95% (CI) was set.

RESULTS: Among the 370 subjects, 105 (28.4%) presented with at least one anomaly. Eighty-five (23%) demonstrated a single anomaly and 20 (5.4%) with more than one anomaly. The most prevalent anomaly was impaction (14.32%), followed by hypodontia (7.03%). The less common anomalies were microdontia (1.08%), dilacerations (0.27%), and generalised enamel hypoplasia (0.27%). Maxillary right lateral incisors and canines were the most common affected teeth and these are located on the maxillary right quadrant. It was evident that dental anomalies were statistically dependant on race (P = 0.025), but independent of gender. The most common treatment planned for these patients was fixed appliance.

CONCLUSIONS: Impaction was predominant among 28.4% subjects observed with anomaly and most patients with anomaly are treated with fixed appliances (49%).

CLINICAL RELEVANCE: These anomalies play a great role in occlusion and alignment in treatment planning and relapse for orthodontic treatment.

Fulltext Can we confidently diagnose pilomatricoma with fine needle aspiration cytology?

Wong YP, Masir N, Sharifah NA

Malays J Med Sci, 2015 Jan-Feb;22(1):84-8.

PMID: 25892955 MyJurnal

Pilomatricomas can be confidently diagnosed cytologically due to their characteristic cytomorphological features. However, these lesions are rarely encountered by cytopathologists and thus pose a diagnostic dilemma to even experienced individuals, especially when the lesions are focally sampled. We describe two cases of histologically confirmed pilomatricoma. The first case is of a 13-year-old boy with posterior cervical 'lymphadenopathy', and the second one is of a 12-year-old girl with a lower cheek swelling. Both aspirates comprised predominantly atypical basal-like cells, with prominent nucleoli. 'Ghost cells' were readily identified by cell block in case two, but cell block in case one yielded no diagnostic material. In case two, pilomatricoma was accurately diagnosed pre-operatively. A cytological suspicion of a neoplastic process was raised in case one. Despite being diagnostically challenging, pilomatricoma can be diagnosed with careful observation of two unique cytological features of the lesions: (1) pathognomonic 'ghost cells' and (2) irregular, saw-toothed, loosely cohesive basaloid cells, with prominent nucleoli. The role of thorough sampling of the lesion, with multiple passes of various sites, cannot be overemphasized.

Dental abnormalities of a long-term survivor of a childhood hematological malignancy: literature review and report of a case

Zarina RS, Nik-Hussein NN

J Clin Pediatr Dent, 2005;29(2):167-74.

PMID: 15719924

The treatment of haematological malignancy is multimodal and involves chemotherapy, radiotherapy and/or bone marrow transplants. With the advancement in cancer therapy, there is an increase in the survival of many children with childhood haematological malignancy. In addition, the late effect of the oncology treatment to the orofacial and dental development becomes significant in terms of the potential clinical impact that may affect the quality of life of the survivor. The severity of the long-term effects is dependent on the age of the child at initiation of treatment and whether chemotherapy is combined with radiation or not. The dental treatment may become more complex if the patient requires advanced restorative dental care and the roots malformation may complicate orthodontic treatment. Therefore these patients may require a scheduled careful preventive programme, long-term follow up, with prophylactic treatment and intervention at appropriate time to minimize the consequences of the disease and the given therapy.

Williams syndrome is a multisystemic rare genetic disorder caused by deletion of 26-28 genes in the long arm of chromosome 7. It is characterized by developmental and physical abnormalities including congenital cardiovascular abnormalities, mental retardation, neurological features, growth deficiency, genitourinary manifestations, gastrointestinal problems, musculoskeletal problems, unique behavioral characteristics, and dental problems. Dental abnormalities include malocclusion, hypodontia, malformed teeth, taurodontism, pulp stones, increased space between teeth, enamel hypoplasia, and high prevalence of dental caries. Authors report a 17-year-old female patient with underlying Williams syndrome. Oral features and problems seen in the patient are listed. Malocclusion and screwdriver shaped teeth were noticed. Generalized widening of the periodontal ligament space with vital teeth was seen. This finding has not been reported in cases of Williams syndrome earlier. Precautions taken during dental treatment in patients with Williams syndrome are also discussed.
