Supernumerary Teeth: A Retrospective Cross-Sectional Study from Palestine

Abstract Objective: To investigate the prevalence and characteristics of supernumerary teeth among patients attending the students' dental clinics at the Faculty of Dentistry of the Arab American University, Jenin, Palestine. Material and Methods: This is a descriptive, cross-sectional, retrospective study of 1970 digital panoramic radiographs of patients, age ranging between 12 and 50 years. The radiographs and dental records were reviewed for supernumerary teeth. For each patient with supernumerary teeth, were recorded the demographic variables, number, location, eruption status, type, and morphology, the developmental stages. Descriptive statistics were performed and results were tabulated. Results: Supernumerary teeth were detected in 17 subjects (0.86%), of which 13 were males and 4 were females with a male to female ratio of 3.25:1. Of the 17 patients, 64.7% had one supernumerary tooth while the others had two. The majority (78.3%) of the supernumeraries were located in the maxilla. Around 56.5% of the supernumeraries found in this study were located in the premaxilla. Half of the supernumeraries (52.2%) were erupted, and 47.8% were impacted. Mesiodens was the most frequently seen supernumerary teeth followed by distomolars and premolars. Most of the supernumeraries were fully developed, while 21.7% displayed only crown formation. Conclusion: The prevalence of supernumerary teeth in the study sample was found to be 0.86% and the most frequent type was mesiodens. Supplemental morphology was found to be the most common form of supernumerary teeth.

Reabilitação do incisivo central decíduo fusionado ao supranumerário: relato de caso clínico / Primary maxillary right central incisor fused to supernumerary: case report

diagnosticadas precocemente. Este trabalho teve como finalidade relatar o caso clínico de uma paciente de três anos, gênero feminino, cuja queixa principal era a estética dos dentes anteriores superiores,devido ao tamanho desproporcional de um elemento dentário, que se apresentava também com coloração alterada. Ao exame clínico e radiográfico diagnosticou-se uma anomalia denominada fusão dentária, união de dois dentes adjacentes, na região anteros superior. O tratamento consistiu na secção dos dois dentes e exodontia do supranumerário, seguida do tratamento restaurador do incisivo central direito que apresentava lesão de cárie. Concluiu-se que, por meio de adequado diagnóstico e planejamento, o tratamento proposto foi efetivo na reabilitação da função e da estética,assim como na prevenção de complicações clínicas e ortodônticas que poderiam advir da anomalia dentária descrita, caso não tratada. A autoestima da criança foi restabelecida.

Dental anomalies can cause serious disorders in the development of teeth if not diagnose dearly. This study aimed to report a case of a three-year-old patient, female, who together with her responsible, whose main complaint was the aesthetics of the upper front teeth due to disproportionatesize and altered staining. During the clinical and radiographic examinations, ananomaly called teeth merger, which is the union of two adjacent teeth, was diagnosed in the upper anterior region. The treatment included the sectioning of the two teeth and extraction of the super numerary, followed by restorative treatment of the right central incisor that had caries lesions. It was concluded that, through proper diagnosis and planning, the proposed treatment was effective in the rehabilitation of function and aesthetics, as well as in the prevention of clinical and orthodontic complications that could result from the dental anomaly described, ifuntreated. The child’s self-esteem was re-established.

Interferencias oclusales y su relación con las maloclusiones funcionales en niños con dentición mixta / Occlusal interferences and its relation with functional malocclusions in children with mixed dentition

Las interferencias oclusales son un problema frecuente en la dentición temporal y mixta, están asociadas a maloclusiones funcionales como mordidas cruzadas anteriores, mordidas cruzadas posteriores, así como anomalías faciales y afectaciones de la articulación temporomandibular. Se realizó un estudio observacional descriptivo de corte transversal, donde fueron examinados 820 niños pertenecientes a escuelas primarias, área de salud Contreras, del municipio de Matanzas, con la finalidad de identificar las interferencias oclusales que se relacionaron con la presencia de mordida cruzada anterior funcional, mordida cruzada posterior unilateral funcional. Del total de niños examinados, 138 presentaron interferencias oclusales, de ellos el 36,9 por ciento presentó mordida cruzada anterior, y un 63,0 por ciento mordida cruzada posterior. La detección precoz de las interferencias oclusales nos dará la posibilidad de la intercepción de maloclusiones dentarias, así como en la prevención de anomalías dentomaxilofaciales y alteraciones de la articulación tempomandibular.

The occlusal interferences are a frequent problem in temporal and mixed dentition. They are associated to functional malocclusions with anterior crossed biting, posterior crossed biting, and also to facial anomalies and affections of the temporomandibular articulation. We carried out a descriptive, observational, transversal study, where we examined 820 primary school children of the Contreras health area, municipality of Matanzas, to identify the occlusal interferences related to the presence of functional anterior crossed biting, functional unilateral posterior crossed biting. 138 of the examined children presented occlusal interferences; 36,9 percent of them presented anterior crossed biting, and 63,0 percent posterior crossed biting. The precocious detection of occlusal interferences will give us the possibility of intercepting dental malocclusions and also of preventing dentomaxillofacial anomalies and alterations of the temporomandibular articulation.

Evaluación del impacto del taller sobre lactancia materna y su rol preventivo en las anomalías dentomaxilofaciales: 2003 / Assessment of the impact of the Braest Feeding and its preventive role in tooh and jaw abnormalities workshop: 2003

A fin de evaluar el impacto del taller de capacitación integral para gestantes sobre la lactancia materna en la prevención de las anomalías dentomaxilofaciales, se realizó un estudio prospectivo y descriptivo en 42 gestantes ingresadas en el bloque ginecoobstétrico del Hospital Provincial Abel Santamaría, en el período comprendido del 1ro. de enero al 31 de marzo de 2003. Los datos se recogieron en un formulario que incluía un examen diseñado al efecto, con el objetivo de evaluar el grado de conocimiento que poseían las gestantes en relación con la importancia de la lactancia materna en la prevención de anomalías dentomaxilofaciales. Las variables analizadas fueron: edad, ocupación, procedencia y resultados de la calificación del examen. Una vez aplicado el examen, se impartió un taller acerca de este tema y posteriormente se les reaplicó a las gestantes el mismo examen. Se obtuvo que el nivel de conocimiento de las gestantes sobre la importancia de la lactancia materna y la función masticatoria en el desarrollo del sistema estomatognático fue inadecuado en los distintos grupos de edad y variables bio-psico-sociales estudiadas, antes de la capacitación. Las temáticas que mayor dificultad tuvieron fueron las relacionadas con el desarrollo adecuado de la mandíbula, la respiración nasal y la deglución. Se concluye que el taller de capacitación impartido a las gestantes tuvo un gran impacto, pues se logró que adquirieran los conocimientos básicos en el amamantamiento natural e introducción de la alimentación sólida y sobre la lactancia materna en la prevención de las anomalías dentomaxilofaciales(AU)

With the objective of assessing the impact of comprehensive training workshop on the role of breast-feeding in the prevention of tooth and jaw abnormalities aimed at pregnant women, a prospective descriptive study of 42 pregnant women, who were admitted to the gynecological-obstetric area of "Abel Santamaría" provincial hospital from January 1st to March 31st, 2003 was conducted. Data were collected into a form that included a test to evaluate the level of knowledge of these women about the importance of breast-feeding in the prevention of tooth and jaw abnormalities. Analytical variables were age, job, origin and test marks. Once the test was applied, participating pregnant women were given a workshop on this topic and later, they made the test again. Before the training course, their level of knowledge on the significance of breast-feeding and the masticatory function on the development of the stomatognatic system was poor at the various age groups and biological and psycho-social variables studied. The most difficult topics were those related with jaw, nasal respiration and deglutition development. It was concluded that the training workshop for pregnant women had a great impact since it succeeded in conveying basic pieces of knowledge about natural feeding and the introduction of solid feeding in addition to the role of breast-feeding in the prevention of tooth and jaw abnormalities(AU)
