- Periodontal regeneration in clinical practice(2006) Alpiste Illueca, Francisco M.; Buitrago Vera, Pedro José; Grado Cabanilles, P. De; Fuenmayor, Vicente; Gil Loscos, FranciscoThe regeneration or restitution of lost supporting tissue has always been considered the ideal objective of periodontal therapy. However, attempts to convert this intention into solid clinical practice can become tremendously complex, the results of which are very different from the original intention. The aim of this article is to offer an up-to-date, general perspective on periodontal regeneration, orienting the clinician within the global strategy for oral treatment. To this end, we revise the healing process of periodontal injury, the different therapeutic approaches, the interpretation of the results, and finally, limiting factors in periodontal regeneration.
- Oral health survey of the child population in the Valencia Region of Spain (2004)(2006) Almerich Silla, José Manuel; Montiel Company, José MaríaIntroducción (fundamento y objetivo): La finalidad de establecer una periodicidad sexenal para estudiar la evolución de salud oral infantil unido a importantes cambios demográficos asociados con la inmigración en la Comunidad Valenciana han motivado este trabajo. Material y método: Con una muestra seleccionada al azar de 509 niños de 6 años, 478 de 12 años y 401 de 15-16 años se ha realizado un estudio de corte transversal. Los exploraciones clínicas fueron realizadas por odontólogos calibrados (Kappa > 0.85). Resultados: La prevalencia de caries en dentición temporal a los 6 años es del 32% (Icod=1.08) y en dentición permanente es de 42.5% a los 12 años (ICAOD=1.07) y del 55.9% a los 15-16 años (ICAOD=1.84). Los niveles de caries en los niños inmigrantes son significativamente altos. La media de sextantes con sangrado fue de 0.16, de 1.58 y de 1.10, mientras que con cálculo fue de 0.15, 0.76 y 0.88 respectivamente. Conclusión: Los niveles de caries tanto en dentición temporal como permanente a los 6 y 12 años se mantienen estables, mientras que a los 15-16 años siguen descendiendo. Los niños inmigrantes, con altos niveles de caries, constituyen un grupo poblacional con importantes necesidades de tratamiento y de aplicación de programas preventivos.
- Aesthetic dentistry : chromatic appreciation in the clinic and the laboratory(2006) Pascual Moscardó, Agustín; Camps Alemany, IsabelAesthetic requirement in dentistry is getting more and more important every day. One of its basic principles is the correct selection of colour for the restorations. Colour is a quality which is modulated by a series of factors, environmental and individual, that the clinic must know. Colour measurement by the human eye can induce to an appreciation mistake if it doesn?t follow a correct protocol of light conditions and observation technique, checked by the authors, simplifying it with a practical focusing. Colour measurement instruments have appeared recently, trying to correct the problems of conventional technique.
- Telescopic crowns in adult case with lip and palate cleft : update on the etiology and management(2006) Mañes Ferrer, José Félix; Martínez González, Amparo; Oteiza Galdón, Begoña; Bouazza Juanes, Kheira; Benet Iranzo, Francisco; Candel Tomás, AnaLip and palatal clefts are among the most important congenital craniofacial malformations to be taken into account in general dental practice, due to their high incidence and important repercussions upon the oral cavity. The underlying causes are genetic and fundamentally environmental, and the disorders manifest as early as in the embryonic period. Males are predominantly affected, with a 7:3 ratio versus females. Our patient, a 20-year-old male, presented the most common association, i.e., total unilateral hare lip with palatal cleft. A description is provided of the treatment for his dental problem, together with an update on the etiology and management of adults with malformations of this kind.

- Antibiotic prophylaxis in pediatric odontology : an update(2006) Planells del Pozo, Paloma; Barra Soto, Mª José; Santa Eulalia Troisfontaines, EvaMost orofacial infections are of odontogenic origin, and are of a self-limiting nature, characterized by spontaneous drainage. The causal bacteria are generally saprophytes. On the other hand, invasive dental interventions give rise to transient bacteremia. When an oral lesion is contaminated by extrinsic bacteria, the required antibiotic treatment should be provided as soon as possible. In the case of pulpitis, such treatment is usually not indicated if the infection only reaches the pulp tissue or the immediately adjacent tissues. In the event of dental avulsion, local antibiotic application is advised, in addition to the provision of systemic antibiotics. The dental professional must know the severity of the infection and the general condition of the child in order to decide referral to a medical center. Prophylaxis is required in all immunocompromised patients, as well as in individuals with cardiac problems associated with endocarditis, vascular catheters or prostheses. Penicillin V associated to clavulanic acid and administered via the oral route is known to be effective against odontogenic infections. In the case of allergies to penicillin, an alternative drug is clindamycin. Most acute infections are resolved within 3-7 days. In recent years, the tendency is to reduce general antibiotic use for preventive or therapeutic purposes.
- A review of facial injuries due to dog bites(2006) Abuabara, AllanBite injuries to the head and neck region can result in facial disfigurement with distressing physical and psychological consequences. This article reviewed the causes and management of facial bite wounds due to dog bites. A PUBMED search of the National Library of Medicine from 1995 to December 2005 was conducted. Keywords used in the search were ?facial wound?, ?bite wound?, ?dog bite?. The results showed that the risk factors for dog attacks include: school-aged children, male, households with dogs, male dogs and certain breeds (german shepherds, bull terriers, blue/red heelers, dobermans and rottwellers). Early management of such complex injuries usually guarantees satisfactory outcome. Most of the cases involve a known dog (friends, neighbors) and family pet. Although animal bites are not the most accounted children injuries, deaths may a result of these attacks. Antibiotic therapy is indicated for infected bite wounds and fresh wounds considered at risk for infection, such as extremely large wounds, large hematoma, and cat bites, that appear be more infected than dog bites. Tetanus immunization status and the risk of rabies infection should be routinely addressed in bite wound management. Prevention strategies should be considered for preventing dog bites.
- Stafne bone cavity : magnetic resonance imaging(2006) Segev, Yoram; Puterman, Max; Bodner, LipaA case of Stafne bone cavity (SBC) affecting the body of the mandible of a 51-year-old female is reported. The imaging modalities included panoramic radiograph, computed tomography (CT) and magnetic resonance (MR) imaging. Panoramic radiograph and CT were able to determine the outline of the cavity and its three dimentional shape, but failed to precisely diagnose the soft tissue content of the cavity. MR imaging demonstrated that the bony cavity is filled with soft tissue that is continuous and identical in signal with that of the submandibular salivary gland. Based on the MR imaging a diagnosis of SBC was made and no further studies or surgical treatment were initated. MR imaging should be considered the diagnostic technique in cases where SBC is suspected. Recognition of the lesion should preclude any further treatment or surgical exploration.
- Incidence of oral sinus communications in 389 upper third molar extraction(2006) del Rey Santamaría, Marta; Valmaseda Castellón, E.; Berini Aytés, Leonardo; Gay Escoda, CosmeIntroducción. La incidencia de las comunicaciones bucosinusales (CBS) tras la extracción del tercer molar superior no se conoce con exactitud. Objetivos. El objetivo de este estudio fue identificar la incidencia de las CBS tras la extracción de 389 cordales superiores realizadas durante el año 2003 en el Máster de Cirugía Bucal e Implantología Bucofacial de la Universidad de Barcelona. Material y método. Se registraron diversas variables con el fin de determinar la relación de la extracción del tercer molar con la incidencia de las CBS: la edad y el sexo del paciente, la angulación del cordal, la técnica quirúrgica y la sospecha radiológica de proximidad con el seno maxilar. Resultados. Únicamente el 5.1% (IC 95%: 2.2-7.3%) de las extracciones quirúrgicas de los cordales superiores provocaron una CBS. El riesgo de producir una CBS fue similar en todos los grupos de edad, y aumentó con la profundidad de inclusión del tercer molar, la complejidad de la técnica quirúrgica y al efectuar ostectomía.
- Retrospective study of 145 supernumerary teeth(2006) Fernández Montenegro, Paula; Valmaseda Castellón, E.; Berini Aytés, Leonardo; Gay Escoda, CosmeObjective: The goal of the present retrospective study is to describe the distribution of the supernumerary teeth in a population of patients that have been attended at the Public Clinic of the Department of Oral Surgery. Background: Supernumerary teeth and multiple hyperdontia are usually associated with different syndromes, such as Gardner syndrome, or with facial fissures; however, they can appear in patients without any pathology. Their prevalence oscillates to 0.5-3.8% in patients with permanent teeth and to 0.35-0.6% in patients with primary teeth. Patients and Methods: A total of 36,057 clinical histories of patients that were admitted at the clinic between September of 1991 and March of 2003 were revised. The following data were extrapolated: age, sex, number of extracted supernumerary teeth, localization, morphology and type of supernumerary teeth. Consequently, 102 patients were included into the present study. Results: Of the 147 supernumerary teeth identified in the oral cavities of patients 145 were extracted. The most frequent supernumerary teeth identified were mesiodens (46.9%), followed by premolars (24.1%) and fourth molars or distal molars (18%). As for location, 74.5% of the supernumerary teeth were found in the superior maxillary bone and 46.9% of the supernumerary teeth were present in the palatine/lingual area. Heteromorphology was found in two thirds of the supernumerary teeth, with conical shape being the most frequent. Finally, 29.7% of the supernumerary teeth had occlusion with permanent teeth, and mesiodens were the predominating type of supernumerary teeth that showed this feature. Conclusions: Mesiodens very frequently cause retention of permanent incisors, which erupt spontaneously after the extraction of supernumerary teeth, if there is sufficient space in the dental arch and if they conserve the eruptive force. Generally, supernumerary premolars are eumorphic and are casually discovered during radiological exam, if not producing any symptomology
- Helicobacter pylori in the dental plaque : is it of diagnostic value for gastric infection?(2006) Chitsazi, Mohammad Taghi; Fattahi, Ebrahim; Farahani, Ramin Mostofi Zadeh; Fattahi, ShirinAim: The aim of the present study was the assessment of association of helicobacter pylori of dental plaque and stomach in a more homogenous population and also to determine the diagnostic value of dental plaque for gastric infection. Materials and Methods: Based on the results of Rapid urease test (RUT) on specimens from gastric antrum, 88 patients with symptoms of dyspepsia were assigned into two groups of infected and non-infected with helicobacter pylori. Supragingival plaque samples were collected from mandibular first and second molar area using and sterile curette and were investigated using RUT. Statistical analysis of data was performed using chi-square test and independent t-test. Results: H.pylori was detected in 34.1 % of dental plaque specimens. The prevalence of helicobacter pylori infection in dental was 31.8 % and 36.4 % in patients with and without gastric infection (P=0.6). Also the interaction of age and infection was not significant but the prevalence of H. pylori both in the dental plaque and the stomach of male patients was higher than female patients. Conclusion: there is not any significant association between the helicobacter pylori of the dental plaque and the stomach. Also the dental plaque can not be used as a primary diagnostic aid for gastric infection.
- Hamular Bursitis and its possible craniofacial referred symptomatology : two case reports(2006) Ramírez, Luis Miguel; Ballesteros, Luis Ernesto; Sandoval, Germán PabloThe diagnosis of craniofacial pain is conditioned by the interdisciplinary management of its presentation especially in the absence of unique and objective signs. Bursitis is a pathological entity recently found in the hamular area and should be included in the diagnosis for exclusion of temporomandibular disorders (TMD), ear-nose-throat pathologies, due to the similar symptomatology to other head and neck conditions. The hamular process bursitis is a painful condition that can easily be confused with glosopharinge or trigeminal neuralgia that generates an uncomfortable feeling in the oropharinge with ipsilateral referred ? heteretopic - symptomatology to the head. This pathology, in chronic states, can be responsible for the amplification of the pain perceived by the central excitation effect. In this report are presented two clinical cases of hamular bursitis and its conservative therapeutic management. The recognition of the inflammation of the bursa of the tensor veli palati muscle supplies the specialist with another tool in the management of craniofacial pain.
- Multiple oral fibropapillomatosis as an initial manifestation of Cowden Syndrome : case report(2006) Capitán Cañadas, L.M.; Salinas Sánchez, J.; Martínez Castillo, Sergio; Labrot Moleón, I.L.; Durán Moreno, David; Sánchez López, José Darío; Valencia Laseca, E.El síndrome de Cowden es una infrecuente enfermedad hereditaria englobada dentro de las poliposis gastrointestinales de tipo hamartomatoso. Se caracteriza por asociar anomalías cutaneomucosas y por la extraordinaria tendencia a desarrollar neoplasias malignas, principalmente de mama y tiroides. La importancia de un diagnóstico precoz del síndrome y de un adecuado screening tumoral en pacientes con lesiones papilomatosas cutaneomucosas, nos va a permitir adelantarnos en el diagnóstico de patologías con enorme morbimortalidad asociada en caso de una detección tardía. Presentamos el caso de una paciente diagnosticada de síndrome de Cowden tras consultar por lesiones papilomatosas labiales de largo tiempo de evolución y tratada posteriormente de cáncer de mama y riñón en estadios iniciales. El correcto diagnóstico de una patología banal de mucosa oral, nos ha permitido actuar de manera muy precoz frente a la patología neoplásica asociada a dicha enfermedad.
- Immunohistochemical evaluation of metallothionein in palatal mucosal cells of mice treated with 4NQO(2006) Aguiar, Maria Cássia Ferreira; Gomes Dos Reis, Daniela; Méricy da Silva, Linaena; Vitorino Cardoso, Sérgio; Alvarez Leite, Jackeline; Vieira do Carmo, María AuxiliadoraObjective: Metallothionein (MT) may play a preventive role in various carcinogenic process. 4NQO is an alkaline compound and potent mutagen that causes the formation of DNA adducts. The purpose of this study was to evaluate the immunoexpression of MT in palatal cells of mice submitted to the carcinogen 4NQO. Study design: C57BL/6 mice received applications of 4NQO to palate for periods of 8, 16, 20 and 24 weeks (experimental group). A control group received only applications of propylene glycol for the same periods. Subsequently animals of experimental and control groups were sacrificed and the palate was histologically analysed and MT immunohistochemistry performed. Results: Although morphological atypical features were scant, the expression of MT was higher in the experimental group in comparison to controls. There was an amplified induction of MT expression in oral epithelium of mice treated by 4NQO. Conclusion: These results suggest that MT may act as an endogenous defensive factor against 4NQO in early phases of oral carcinogenesis.
- Follicular adenomatoid odontogenic tumor : immunohistochemical study(2006) Vera Sempere, Francisco José; Artes Martínez, María José; Vera Sirera, Beatriz; Bonet Marco, JaimeAdenomatoid odontogenic tumor (AOT) is an uncommon benign odontogenic lesion that affects young patients, with female predominance, mainly in second decade, showing a radiolucent unilocular image associated with an unerupted tooth, usually a canine. In spite of previous and confusing denominations, such as adenoameloblastoma or adenomatoid ameloblastic tumor, AOT is a benign tumor with a very low rate of recurrence, that show a peculiar morphological picture (basaloid appearance with glandular-like structures, calcifying areas, and amiloid-like material) that allow its histopathological recognition. We present a clinicopathological analysis of a case of follicular AOT affecting the mandible in a 9 years-old female patient associated with unerupted lower left canine. Immunohistochemical study showed some data previously unrecognised. All cellular types that composed AOT showed nuclear positivity for p63 indicating a basal characterization in the different cellular components. According to its benign character and low potential for recurrence, AOT revealed a scant proliferative activity (2-3% nuclei showed Ki-67 positivity) limited to some epithelial nodules (AE1-3 +) of fusiform appearance. Absence of reactivity for hormonal receptors (RE and RPg) excluded a possible hormonodependence in AOT that could explain the observed female predominance.
- Structural and functional salivary disorders in type 2 diabetic patients(2006) Carda Batalla, María del Carmen; Mosquera Lloreda, Nezly; Salom, Lucas; Gómez de Ferraris, María Elsa; Peydró Olaya, AmandoDiabetes mellitus type 2 is the most common metabolic disorder and it causes an important morbimortality. The structural modifications in the parotid gland (sialosis) had already been described in these patients and could result in variations in the salivary composition, as well as an increase in periodontal and dental pathology. Objectives: to compare the biochemical findings in the saliva and to correlate these biochemical disturbances with the morphologic findings previously described. Patients and methods: clinical information were gathered about 33 patients, 17 had type 2 diabetes. Samples of whole saliva were obtained for biochemical analysis and serum samples to determine metabolic control. Results: in the diabetics saliva we found urea and total proteins increased and reduced levels of microalbumina. Salivary glucose was only augmented in patients with poor metabolic control. Clinical symptoms of xerostomia were present in 76,4% and dental and periodontal disease in 100%. The parotid gland was characterised by the presence of small acini, lipid intracytoplasmic droplets, as well as adipose stroma infiltration. The acinar cytoqueratins? expression was heterogeneous and very positive in the hyperplasic ducts. Conclusions: these biochemical disorders in the saliva of the type 2 diabetic patients would be related with the structural changes previously observed in parotid glands.
- Delayed contact sensitivity on the lips and oral mucosa due to propolis-case report(2006) Brailo, Vlaho; Vucicevic Boras, Vanja; Alajbeg, Iva Z; Vidovic Juras, DanicaWe report a rare case of a patient who was referred to the Department of Oral medicine in Zagreb, Croatia. The patient was 20 years old, otherwise healthy and not taking any medication. She presented with irregular erosions partially covered with pseudomembranes that involved both lips and retrocomissural mucosa. Discrete erosion was also noticed on her lower lingual gingiva in the area 42. She reported a propolis solution self-medication for treatment of recurrent aphthous ulcers. After ten days of propolis application, lip and oral lesions developed. Patch test to propolis was proven. We highlight the fact that some folk medicine medications, such as propolis, although being known for many decades to be helpful in various conditions, in some individuals might lead to unwanted side-effects due to its antigenic potential. Additionally, every colleague, during the differential diagnosis of the oral lesions must bear in mind unwanted reactions to folk medicine products.
