Clinical Approach of Ankyloglossia in Babies: Report of Two Cases

Ankyloglossia is a developmental anomaly of the tongue characterized by a short lingual frenum, resulting in restricted movement of the tongue. Its etiology is undefined and there is no gender preference. Few studies are available in the literature and the diagnosis and management of ankyloglossia in infants remains controversial. We report two cases of infants submitted to lingual frenectomy, emphasizing the management of ankyloglossia and its implications in breast-feeding.

Mucus extravasation and retention phenomena: a 24-year study

Background: Mucoceles are benign lesions related to the minor salivary glands and their respective ducts frequently affecting oral structures which are generally asymptomatic. Mucoceles are generally characterized by swollen nodular lesions preferentially located on the lower lip and differ from the so-called ranulas, which are lesions located on the floor of the mouth and related to the sublingual or submandibular glands.Methods: The objective of the present study was to analyze data such as age, gender, race and site of the lesion of 173 mucocele cases diagnosed at the Discipline of Stomatology, Sao Jose dos Campos Dental School, UNESP, over a period of 24 years (April 1980 to February 2003).Results: of the 173 cases analyzed, 104 (60.12%) were females and 69 (39.88%) were males. Age ranged from 4 to 70 years (mean +/- SD: 17 +/- 9.53) and most patients were in the second decade of life (n = 86, 49.42%); white (n = 124, 71.68%). The lower lip was the site most frequently affected by the lesions (n = 135, 78.03%), whereas the lowest prevalence was observed for the soft palate, buccal mucosa, and lingual frenum.Conclusion: In this study, mucoceles predominated in white female subjects in the second decade of life, with the lower lip being the most frequently affected site.

Clinical manifestations and oral findings in fraser syndrome

This article is the first known case report of Fraser syndrome in the dental literature. Its purpose was to present the clinical manifestations, oral findings, and dental treatment of a 14-year, 10-month-old female patient. Fraser syndrome is a rare recessive autosomal genetic disorder characterized by multisystemic malformation, usually comprising cryptophthalmos, syndactyly, and renal defects. The child presented with: (1) hydrocephaly; (2) face asymmetry; (3) low-inserted ears; (4) flat nose bridge; (5) cryptophthalmos; (6) bilateral absence of eyeballs; (7) hypertelorism; (8) syndactyly on the left fingers and toes; (9) skeletal defects; and (10) lower limb asymmetry. The intraoral examination revealed: (1) complete primary denture; (2) malocclusion; (3) tooth crowding; (4) ogival palate; (5) normal labial frena; (6) absence of lingual frenum (not compromising the tongue movements); (7) parched lips; (8) supragingival calculus adhered to all tooth surfaces; and (9) moderate gingivitis. The dental treatment consisted of periodic monitoring of the patient's oral health status and supragingival scaling associated with topical applications of 0.12% chlorhexidine digluconate gel at 2-week intervals to reduce gingivitis.

Freqüência de anquiloglossia em uma comunidade indígena brasileira

Objective: This study aimed to assess the prevalence of ankyloglossia in people of different age groups living in the native Brazilian community of Umutina, in the municipality of Barra do Bugres/Mato Grosso. Methods: The sample consisted of 291 native Brazilians who underwent clinical examination. Results: Ankyloglossia was observed in 108 (37.11%) individuals. There was a greater prevalence of ankyloglossia among males, with 57 cases (43.8%) against 51 cases (31.7%) in females. Age distribution was done after analyzing the hierarchical grouping, resulting in three age groups: 1- to 20-year-olds, 21- to 45-year-olds and 46- to 99-year-olds. Ankyloglossia was more prevalent in the youngest group, with 65 cases (40.6%). Conclusion: Although there is a high rate of ankyloglossia among the individuals who live in the Umutina Reservation, ankyloglossia does not seem responsible for the changes associated with phonation, mastication, presence of diastema and periodontal problems, since these changes were infrequent and generated no complaints.

Diferenças biomecânicas entre a técnica lingual e a labial

Pela sua característica essencialmente estética, o aparelho lingual vem despertando interesse por parte dos ortodontistas e da comunidade em geral. O crescente mercado dos serviços de beleza, em todos os setores (médicos, odontológicos, cosméticos), influencia o ressurgimento da técnica lingual. Biomecanicamente diferente da técnica convencional, a técnica lingual necessita de um conhecimento e treinamento diferenciado do profissional que a executa. Verificar as diferenças, encontradas na literatura, com relação às duas técnicas é o objetivo deste trabalho, como parte do processo de amadurecimento e treinamento profissional confirmando a técnica lingual como mais uma opção segura de tratamento ortodôntico.

Medidas operantes de limiar auditivo em crianças com surdez pré-lingual, usuárias de implante coclear

Limiares auditivos de crianças surdas pré-linguais usuárias de implante coclear foram avaliados com estimulação elétrica em um dos eletrodos mediais. A avaliação empregou um procedimento operante do tipo go/no go para ensinar uma discriminação simples, evidenciada por uma resposta motora, entre presença e ausência do estímulo auditivo. Estabelecida a linha de base, a manipulação na intensidade do estímulo foi implementada de acordo com o método psicofísico de escada modificado, começando por uma seqüência descendente. Os sete participantes do estudo mostraram perda da precisão no responder sob controle do estímulo quando a intensidade diminuía além de um certo valor e a precisão era recuperada quando a intensidade era novamente aumentada, o que permitiu a identificação de limiares individuais. Os resultados sugerem que o método psicofísico combinado com o procedimento operante pode ser uma alternativa viável para avaliar limiar auditivo de pessoas sem linguagem em situação clínica de regulagem do implante coclear.

Disfunção temporária do nervo lingual após uso de máscara laríngea. Relato de caso

BACKGROUND AND OBJECTIVES: The laryngeal mask has been frequently used in Anesthesiology. Although the rate of complications with this technique is smaller than that of the endotracheal tube, it is not devoid of risks, especially in cases of difficult airways. The objective of this study was to report a case of unilateral lingual nerve damage after the use of the laryngeal mask airway. CASE REPORT: A female patient underwent a surgical procedure for removal of bilateral breast prosthesis under general, balanced anesthesia, with a size three laryngeal mask. The balloon was inflated with 30 mL of air. After the first postoperative hour, she developed decreased sensation and pain in the oropharynx and posterior two thirds of the tongue, which evolved for loss of taste in the next 24 hours. A tentative diagnosis of lingual nerve neuropraxis secondary to the use of the laryngeal mask was made. After three weeks, her symptoms subsided. CONCLUSION: Although complications after the use of the laryngeal mask airway are rare, they do occur, and neuropraxis of the lingual nerve is one of them. The diagnosis is clinical and it has a good outcome, with resolution of the symptoms within a few weeks or months. © Sociedade Brasileira de Anestesiologia, 2007.

A practical method for lingual retainer fixation before direct bonding: Clinical suggest

The retention phase is initiated after orthodontic treatment completion to prevent orthodontic relapse. There are several techniques, direct and indirect, available for placing bonded lingual retainers, but none of them is considered as a standard clinical protocol. The best choice should be the association of simplicity and efficiency. This article presents a practical method sequence for fixation of the lingual retainer before direct bonding. © 2009 Elsevier Ltd and the Japanese Orthodontic Society.

In vitro lingual bracket evaluation of indirect bonding with plasma arc, LED and halogen light

Authors - Magno AFF, Martins RP, Vaz LG, Martins LP Objectives - Evaluate the shear bond strength (SBS) and the adhesive remnant index (ARI) of indirect bonded lingual brackets using xenon plasma arc light, light-emitting diode (LED) and conventional quartz-tungsten-halogen light. Material and Methods - Lingual brackets were bonded indirectly to 60 premolars divided to three groups according to the curing light used: Group 1, plasma arc for 6 s; Group 2, LED for 10 s; and Group 3, halogen light for 40 s. After bonding, the specimens were subjected to a shear force until debonding. The debonding pattern was assessed and classified according to the ARI scores. The mean shear bond strengths were accessed by anova followed by the Student-Newman-Keuls test for multiple comparisons. ARI scores were assessed using the chi-square test. Results - The three groups showed significant differences (p < 0.001), with the averages of group 1 < group 2 < group 3. Groups showed no differences regarding ARI scores. Conclusion - Bonding lingual brackets indirectly with plasma arc, during 60% of the time used for the LED, produced lower SBS than obtained with the latter. Using LED during 25% of the time of the halogen light produced lower SBS than obtained with the latter. These differences did not influence the debonding pattern and are clinically acceptable according to the literature. © 2010 John Wiley & Sons A/S.
