Comparative Evaluation of Clinical Efficacy of Diode LASER and Cryosurgery for Gingival Pigmentation: A Split-Mouth Randomized Clinical Study

ABSTRACT Objective: To compare and evaluate the clinical efficacy of diode laser and cryosurgery for treating melanin pigmentation of gingiva. Material and Methods: A total of twenty-five subjects with physiological gingival pigmentation on the facial aspect of both maxillary and mandibular anterior arches (50 sites), both male and female, with an average age ranging from 18-35 years, participated in the study. The sites were randomly divided into Group I: depigmentation by Laser and Group II: depigmentation by Cryosurgery. The following parameters were assessed for the evaluation of treatment results: Melanin Oral Pigmentation Index (PI), Visual Analogue Scale (VAS) for pain evaluation and Healing index (HI). The data collected was statistically evaluated. Results: On intergroup comparison, there was no statistical difference in the score from baseline (p>0.05); however, a statistically significant difference was seen at the end of 1 year (p<0.05). Moreover, 57-60% of arches showed recurrence of pigmentation in the laser group whereas; only 12.7-17% recurrence was seen in the cryosurgery group at the end of the first year. Conclusion: Treatment of gingival hyperpigmentation with laser and cryosurgery shows a marked improvement of gingival pigmentation in both groups, but the cryosurgery depigmentation sites showed more sustainability.

A comparative study to evaluate the effects of antibiotics, plant extracts and fluoride-based toothpaste on the oral pathogens isolated from patients with gum diseases in Pakistan / Um estudo comparativo para avaliar os efeitos de antibióticos, extratos vegetais e creme dental à base de flúor sobre os patógenos orais isolados de pacientes com doenças gengivais no Paquistão

Oral diseases caused by various microorganisms are common around the world. Scientific research has now been focusing on novel medicines to overcome bacterial resistance and antibiotics side effects; therefore, the current study was designed to assess the efficacy of certain antibiotics, toothpaste, and medicinal plant extracts (Ajuga bracteosa and Curcuma longa) versus the bacterial pathogens isolated from the human oral cavity. A total of 130 samples were collected from Khyber Teaching Hospital Peshawar, Pakistan, among those 27 species isolated, and eight bacterial species were identified from the samples. Among all the bacterial species, Staphylococcus aureus (29.62%) and Proteus mirabilis (22.2%) were found to be more prevalent oral pathogens. In comparison, the least pervasive microbes were Proteus vulgaris, Shigella sonnei, Escherichia coli and Aeromonas hydrophila. The study also suggested that dental problems were more prevalent in males (41-50 years of age) than females. Among the eight antibiotics used in the study, the most promising results were shown by Foxicillin against A. hydrophila. The survey of TP1 revealed that it showed more potent antagonist activity against Proteus vulgaris as compared TP2 and TP3 that might be due to the high content of fluoride. The Curcuma longa showed more significant activity than Ajuga bracteosa (Stem, leaves and root) extracts. The data obtained through this study revealed that antibiotics were more effective for oral bacterial pathogens than toothpaste and plant extracts which showed moderate and low activity, respectively. Therefore, it is suggested that the active compounds in individual medicinal plants like Curcuma longa and Ajuga bracteosa could replace the antibiotics when used in daily routine as tooth cleansers or mouth rinses.

As doenças bucais causadas por vários microrganismos são comuns em todo o mundo. A pesquisa científica agora tem se concentrado em novos medicamentos para superar a resistência bacteriana e os efeitos colaterais dos antibióticos; portanto, o presente estudo foi desenhado para avaliar a eficácia de certos antibióticos, pasta de dente e extratos de plantas medicinais (Ajuga bracteosa e Curcuma longa) contra os patógenos bacterianos isolados da cavidade oral humana. No total, 130 amostras foram coletadas do Khyber Teaching Hospital Peshawar, Paquistão, entre essas, 27 espécies foram isoladas e oito espécies bacterianas foram identificadas a partir das amostras. Entre todas as espécies bacterianas, Staphylococcus aureus (29.62%) e Proteus mirabilis (22.2%) foram os patógenos orais mais prevalentes. Em comparação, os micróbios menos difundidos foram Proteus vulgaris, Shigella sonnei, Escherichia coli e Aeromonas hydrophila. O estudo também sugeriu que os problemas dentários eram mais prevalentes em homens (41-50 anos de idade) do que em mulheres. Entre os oito antibióticos usados no estudo, os resultados mais promissores foram mostrados pelo Foxicillin contra A. hydrophila. A pesquisa de TP1 revelou que ele mostrou atividade antagonista mais potente contra Proteus vulgaris em comparação a TP2 e TP3, o que pode ser devido ao alto teor de flúor. A Curcuma longa apresentou atividade mais significativa em relação aos extratos de Ajuga bracteosa (caule, folhas e raiz). Os dados obtidos neste estudo revelaram que os antibióticos foram mais eficazes para os patógenos bacterianos orais do que os dentifrícios e os extratos vegetais que apresentaram atividade moderada e baixa, respectivamente. Portanto, sugere-se que os compostos ativos em plantas medicinais individuais como Curcuma longa e Ajuga bracteosa possam substituir os antibióticos quando usados na rotina diária como limpadores de dentes ou enxaguatórios bucais.

Gingival state and presence of red complex bacteria in 12-Year-Old schoolchildren / Estado gingival y presencia de bacterias del complejo rojo en escolares de 12 años

Abstract The objective of this study was to determine the gingival state and presence of red complex bacteria in saliva samples of 12-year-old schoolchildren. A calibrated periodontist evaluated biofilm index (BI) (Silness and Löe, 1964), presence of calculus, and gingival index (GI) (Silness and Löe, 1967) in sixty two 12-year-old students of Carmen Lyra School. Saliva samples were collected from each student. The DNA of each sample was extracted and amplified by the polymerase chain reaction (PCR) technique, using specific primers. The BI was 1.18. Calculus was present in 40.40% of the schoolchildren examined; 19.4% was supragingival calculus and 21% both supragingival and subgingival calculus. The GI was 0.97, which according to Silness and Löe is mild gingivitis. Gingivitis was present in 96.8% of the children examined. Regarding the PCR tests: 18 of the samples (31.58%) did not present any of the bacteria analyzed and the remaining 39 samples (68.42%) were positive for at least the presence of red complex bacteria. Within the limitations of this study, it is concluded that the prevalence of gingivitis and calculus is high in the sample examined, and the gingival state observed in the study population, may be related to the presence of red complex bacteria.

Resumen El objetivo de este estudio era determinar el estado gingival y la presencia de bacterias del complejo rojo en muestras de saliva de niños de 12 años de la Escuela Carmen Lyra. Una periodoncista calibrada evaluó en 62 estudiantes de 12 años de la Escuela Carmen Lyra, el índice de biofilme (IB) (Silness y Löe, 1964), la presencia de cálculo y el índice gingival (IG) (Silness y Löe, 1967). Se recolectaron muestras de saliva de cada estudiante. El ADN de cada muestra fue extraído y amplificado por medio de la prueba PCR, empleando primers específicos, para determinar la presencia de bacterias del complejo rojo. El IB fue de 1.18. El cálculo estuvo presente en el 40.40% de la muestra, se encontró 19.4% de cálculo en supragingival y 21% tanto en supragingival como en subgingival. El IG fue de 0.97, que de acuerdo con Silness y Löe es una gingivitis leve. La gingivitis estuvo presente en el 96.8 % de los niños examinados. Con respecto a las pruebas PCR: 18 de las muestras (31.58 %) no presentaron ninguna de las bacterias analizadas y las 39 muestras restantes (68.42%) fueron positivas por lo menos a la presencia de las bacterias del complejo rojo. Dentro de las limitaciones de este estudio, se concluye que la prevalencia de gingivitis y cálculo es alta en la muestra examinada y el estado gingival observado puede estar relacionado con la presencia de bacterias del complejo rojo.

Granuloma piógeno oral. Serie de casos / Oral pyogenic granuloma. Case series

RESUMEN El granuloma piógeno es una lesión que se manifiesta en la piel y en la cavidad oral, relacionado con diversas causas, como irritación crónica, trauma y cambios hormonales. Clínicamente se muestra como una lesión hiperplásica altamente vascularizada, con un tamaño de 1-3 cm, de base pedunculada o sésil y de crecimiento lento. Predomina en el sexo femenino y tiende a aparecer, sobre todo, en la encía, con muy pocos casos reportados en zonas edentes, motivo por el que se realizó el reporte de tres casos de granuloma piógeno oral en pacientes femeninas, comprendidas entre 30 y 40 años de edad. Se presentaron lesiones que diferían en cuanto a su localización y apariencia clínica (AU).

ABSTRACT Pyogenic granuloma is a lesion that arises in the skin and oral cavity, related to various causes, such as chronic irritation, trauma and hormonal changes. Clinically it looks like a highly vascularized hyperplastic lesion, sized 1-3 cm, with a pedunculated or sessile base and slow growing. It predominates in the female sex and tends to appear, above all, in the gum, with very few cases reported in edentulous areas; that is why the authors reported three cases of oral pyogenic granuloma in female patients, aged between 30 and 40 years. The lesions differed in their location and clinical appearance (AU).

Non-surgical periodontal treatment for drug-influenced gingival enlargement: a four-year follow-up case report

ABSTRACT: Drug-influenced gingival enlargement is considered to be an important side effect related to the use of some medications and often produces important esthetic changes for patients, as well as clinical symptoms such as pain, bleeding, abnormal tooth movement and occlusion problems. Anticonvulsants, immunosuppressants and antihypertensive drugs have been reported as the main inducers of these periodontal disorders. This case report describes the 4-year clinical follow-up of a young patient with a history of excessive gingival enlargement as a consequence of drug therapy for epilepsy (phenytoin and phenobarbital); the nonsurgical periodontal treatment of the excessive gingival enlargement was associated with the replacement of the patient's epilepsy medications with valproic acid. We conclude that intensive mechanical control of bacterial biofilms, instruction on oral hygiene guidelines and behaviors and the substitution of alternative anticonvulsant medications are the best way to control the drug-influenced gingival enlargement.

Utilización de láser diodo en tejidos blandos: reporte de 3 casos / Use of diode laser in soft tissue: report of 3 cases

Existen diversas condiciones anatómicas o alteraciones mucogingivales que pueden afectar tanto el normal funcionamiento como la estética gingival de piezas dentarias e implantes dentales. Si bien los tratamientos de estas condiciones se han realizado tradicionalmente con bisturí, el desarrollo tecnológico ha permitido que actualmente se pueden realizar con láser. Existen diferentes tipos de láser, siendo el diodo uno de los más utilizados debido a su menor tamaño, portabilidad, fácil configuración y menor costo. El láser ha adquirido mayor popularidad en cirugías de tejido blando dado sus múltiples beneficios: menor tiempo operatorio, control del sangrado y de la hemostasia, reducción de la cantidad de anestesia, posibilidad de no requerir suturas y minimización del dolor e inflamación postquirúrgica. El propósito de este trabajo es presentar la resolución de tres casos clínicos a los cuales se les realizaron los procedimientos de frenectomía labial, remoción de melanosis gingival y resección de fibroma irritativo mediante el uso de láser diodo. Para desarrollar todos los procedimientos se utilizó un equipo de láser diodo de 940 nm (Biolase®, USA) con una potencia que varió entre 2 y 2.5 W en modo continuo utilizando una pieza quirúrgica con una punta de 300 µm (E 3-4), la que fue activada antes de empezar. Posterior a la cirugía se bioestimuló para disminuir el dolor y edema postoperatorio utilizando la punta de dolor a 4 W por 30 segundos a una distancia de 1 cm directo en la zona intervenida a todos los casos. La conclusión arroja que en todos los casos, el láser de diodo permitió un resultado exitoso. El procedimiento fue seguro, la técnica fue sencilla y de tiempo clínico reducido. El postoperatorio ocurrió con ausencia de dolor o molestias, generando una mayor satisfacción del paciente. Cabe señalar que la técnica depende de la habilidad del profesional que la realiza.

There are various anatomical conditions or mucogingival alterations that can affect the normal functioning and the gingival aesthetics of teeth and dental implants. Although the treatments of these conditions have been traditionally performed with a scalpel, technological development has allowed that they can be now performed with lasers. There are different types of lasers, being the diode one of the most used due to its smaller size, portability, easy configuration, and lower cost. The laser has become more popular in soft tissue surgeries due to its multiple benefits: shorter operating time, control of bleeding and hemostasis, reduction in the amount of anesthesia, possibility of not requiring sutures, and minimization of post-surgical pain and inflammation. The purpose of this work is to present the resolution of three clinical cases which underwent labial frenectomy procedures, removal of gingival melanosis and resection of irritative fibroma using diode laser. To develop all the procedures, a 940 nm diode laser equipment (Biolase®, USA) was used with a power that varied between 2 and 2.5 W in continuous mode, using a 300 µm tip (E 3-4), which was activated before starting. After surgery, biostimulation was carried out to reduce postoperative pain and edema using the pain tip at 4 W for 30 seconds at a distance of 1 cm directly in the operated area in all cases. In all cases, the diode laser allowed a successful result. The procedure was safe, the technique was simple, and the clinical time was short. The postoperative period occurred with the absence of pain or discomfort, generating greater patient satisfaction. It should be noted that the technique depends on the skill of the professional who performs it.

Perceptions of the Use of the Diode Laser in Dental Surgery: A Qualitative Study

Abstract Objective: To discover the perceptions of pediatric patients, their parents and undergraduate Dentistry students of the use of the diode laser in frenectomy surgeries. Material and Methods: A qualitative study was conducted through semi-structured interviews, recorded and transcribed with subsequent content analysis. Twelve healthy children (5-8 years old) who needed a frenectomy were selected and invited, together with their parents, to undergo laser diode surgery. In addition, 28 undergraduate dentistry students were invited to attend the procedures. One week after performing the surgical procedures, the children (Group 1), their parents (Group 2) and the students who attended the procedures (Group 3) were individually interviewed for the thematic analysis. Results: The analysis of the conversations identified three emerging contents: positive thoughts on the use of diode laser; frustrations from the use of diode laser; and aspects related to professional training. Conclusion: The results pointed to the acceptance of surgical laser use in pediatric dentistry; however, the feelings of frustration indicate that its use requires guidance from the child and his/her parents, in addition to careful handling and specific training.

Gingival Melanin Depigmentation With Diode Laser - Case Report / Despigmentación Melánica Gingival con Láser de Diodo - Relato de Caso

ABSTRACT: The pigmented lesions of the oral cavity may be endogenous or exogenous. Endogenous lesions are benign and usually caused by melanin, and they are called gingival melanin pigmentations. Among the options for depigmenting these areas, laser therapy stands out for being a minimally invasive procedure. This study aims to report a clinical case of the gingival depigmentation technique using a high-power diode laser in the anterior maxillary region, for the ablation of the pigmented tissue to improve gingival aesthetics. The patient had an aesthetic complaint of the darkened aspect of the gingiva in the anterior maxillary and mandibular portions. After local anesthesia, we started depigmentation with high-power diode laser and performed ablation from the attached gingiva toward the free marginal gingiva. The patient returned after 30 and 180 days presenting healthy gingiva and absence of melanin repigmentation. Thus, we concluded that the diode laser was a good alternative for melanin depigmentation because it is a procedure with lower morbidity and satisfactory postoperative results.

RESUMEN: Las lesiones pigmentadas de la cavidad oral pueden ser endógenas o exógenas. Las endógenas son benignas y generalmente causadas por la melanina, denominándose pigmentaciones melánicas gingivales. Entre las opciones para la despigmentación de estas regiones, se destaca la laserterapia, por ser un procedimiento poco invasivo. Este trabajo tuvo como objetivo relatar un caso clínico de la técnica de despigmentación gingival utilizando láser de diodo de alta intensidad en la región anterior de los maxilares para ablación del tejido pigmentado con la finalidad de mejorar la estética gingival. El paciente presentaba como queja estética el aspecto oscurecido de la encía en la región anterior de la maxila y de la mandíbula. Tras aplicar anestesia local, se inició la despigmentación con láser de diodo de alta intensidad, siendo que la ablación se realizó a partir de la encía insertada hacia la encía marginal libre. El paciente regresó tras 30 y 180 días, presentando encía saludable y con ausencia de repigmentación melánica. Así fue posible concluir que el láser de diodo mostró ser una buena alternativa para la despigmentación melánica, ya que se presentó como un procedimiento con menor morbidad y buen resultado postoperatorio.

Granuloma Periférico de Células Gigantes e Hiperparatiroidismo. Presentación de un Caso / Peripheral Giant Cell Granuloma and Hyperparathyroidism. Case Report

RESUMEN: Se presenta el caso de un paciente sexo femenino 31 años, insuficienciente renal crónica en hemodiálisis, hipertensa secundaria, consulta por aumento de volumen oral en relación a encía marginal vestibular izquierda, 6 meses de evolución. Al examen se observa aumento de volumen de 15 mm en relación a piezas. 3.6 y 3.7. Radiografía muestra compromiso periodontal pieza 3.7. Se realiza biopsia excisional y exodoncia pieza 3.7. Histopatología informa granuloma periférico de células gigantes. Se solicitan exámenes de laboratorio para estudio de hiperparatiroidismo (PTH elevada, calcemia fosfatemia normales). Evoluciona favorablemente. Sin signos de recidiva a los 3 meses. El diagnóstico histopatológico de lesión de células gigantes debe ser complementado con la clínica, exámenes de laboratorio e imagenología, el objetivo final es definir si tal diagnóstico corresponde a un tumor pardo, a un granuloma central de células gigantes o a un granuloma periférico de células gigantes. En la literatura los reportes de asociación entre granuloma periférico de células gigantes e hiperparatiroidismo son escasos. Este caso corresponde a granuloma periférico células gigantes, asociado a hipersecreción de paratohormona.

ABSTRACT: A 31-year-old female patient with chronic renal insufficiency in hemodialysis and secondary hypertension consulted due to an enlarging intraoral lesion in relation to the left marginal vestibular gingival, with 6 months of evolution. A 15mm mass in relation to mandibular left molars was noted. Radiograph showed periodontal involvement of mandibular left second molar. Excisional biopsy and tooth 3.7 extraction were performed. Histopathology reported a peripheral giant cell granuloma. Laboratory tests were requested for suspected hyperparathyroidism (aiding in the diagnosis) (high PTH, normal phosphatemia and calcemia). Evolution was favorable, without signs of reappearance after 3 months. The histopathological diagnosis of giant cell lesions should be complemented with clinical, laboratory and imaging tests. The final objective is to make the differential diagnosis between brown tumor, central giant cell granuloma and peripheral giant cell granuloma because the treatment varies considerably. There are few reports in the literature about the association between peripheral giant cell granuloma and hyperparathyroidism. This case corresponds to peripheral giant cell granuloma, possibly associated with parathormone hypersecretion.

Hallazgos Histopatológicos del Tejido Pericoronario de Terceros Molares Incluidos Sanos / Histopathological Findings of Pericoronary Tissue in Healthy Third Molars

RESUMEN: Este estudio se realizó para evaluar la presentación de cambios histopatológicos tempranos en sacos pericoronarios de terceros molares incluidos sanos. Sesenta y un tejidos pericoronarios de terceros molares incluidos, clínicamente asintomáticos y sin evidencia radiográfica de anomalía del saco pericoronario, se extrajeron por diferentes razones. Las muestras se fijaron y procesaron de forma rutinaria y se tiñeron con hematoxilina-eosina antes de la evaluación. Se estandarizaron los diagnósticos concluyendo que toda muestra que presente metaplasia escamosa del epitelio reducido del órgano del esmalte (EEE) se considerará cambio quístico temprano. De las muestras presentadas, el 28 % mostró metaplasia escamosa sugerente de cambio quístico temprano. Esta variación histológica del tejido pericoronario fue significativamente mayor en los pacientes menores de 20 años de edad, sexo femenino, terceros molares mandibulares, en inclusión ósea y en pacientes que no informaron sintomatología local previa (P = 0,05). Estos hallazgos sugieren que la ausencia de semiología clínica y radiográfica en terceros molares incluidos no necesariamente indica ausencia de alteraciones en el tejido pericoronario de los mismos.

ABSTRACT: This study was performed to evaluate the presentation of early histopathological changes in pericoronal healthy third molars. Sixty-one pericororonitis tissues third molars, without radiographic evidence of abnormality in pericoronary sack, extracted for various reasons. The samples were fixed and processed routinely and stained with hematoxylin-eosin before evaluation. Diagnostic standardized concluding that all this shows that squamous metaplasia of the reduced enamel organ (EEE) is considered cystic epithelium were early change. Of the samples submitted, 28 % showed squamous metaplasia early suggestive of cystic change. This histological tissue pericoronary variation was significantly higher in patients under 20 years of age, female gender, mandibular third molars, including in bone and in patients who reported no previous local symptoms (P = 0.05). These findings suggest that the absence of clinical and radiographic semiology third molars does not necessarily indicate the absence of alterations in tissue pericoronary thereof.

Complicaciones y cicatrización del injerto libre de encía y el colgajo de reposición coronal / Complications and healing of the free gingival graft and the coronally repositioned flap

RESUMEN La recesión periodontal se define como un trastorno de instalación lenta, progresiva y destructiva, en la cual, la encía adherida de uno o varios dientes se encuentra apical a la unión cemento-esmalte. Se realizó un estudio descriptivo y transversal desde enero 2014 a diciembre 2016, en la Facultad de Estomatología de Villa Clara, con el objetivo de describir las principales complicaciones y la cicatrización del injerto libre de encía y el colgajo de reposición coronal asociado a injerto de tejido conectivo subepitelial. La muestra fue de 45 pacientes y 54 zonas de injerto. Las complicaciones postoperatorias más frecuentes fueron: el dolor, seguido de la gingivorragia postoperatoria y el edema, en los casos donde se empleó el injerto libre de encía. La cicatrización de la zona donante y receptora, evaluada de buena, fue superior con el empleo del colgajo de reposición coronal asociado al tejido conectivo subepitelial.

ABSTRACT Periodontal recession is defined as a destructive and slowly progressive disorder, in which the attached gingiva of one or several teeth is apical to the cement-enamel junction. A descriptive and cross-sectional study was carried out from January 2014 to December 2016, in the Faculty of Dentistry of Villa Clara, with the aim of describing the main complications and healing of the free gingival graft and the coronally repositioned flap associated with subepithelial connective tissue graft. The sample consisted of 45 patients and 54 graft areas. The most common postoperative complications were pain, followed by postoperative gingival bleeding and edema, in cases where free gingival graft was used. The healing of the donor and recipient area, evaluated as good, was superior with the use of the coronally repositioned flap associated with subepithelial connective tissue.

Severity of periodontal disease in smokers

Introduction: The objective of the present study was to evaluate the severity of periodontal disease in a population of adults with gingival or periodontal disease who assist at the periodontics service of the Faculty of Dentistry of the National University of Rosario. Methods: The study evaluated the periodontal conditions in smokers and non smokers. The sample consisted of 400 individuals: 268 non-smokers (NS) and 132 active smokers (S). The classification of gingival and periodontal diseases was based on the criteria of the American Association of Periodontology (2017), recruiting patients with diagnoses of gingivitis, stage II, III and IV of periodontitis. Each one of these pathologies was related to the different age groups to assess the risks of clinical attachment loss. The periodontal variables studied were: probing depth (PD), attachment level (AL), number of teeth present (TP), oral hygiene index (OHI), tooth mobility (M) and bleeding on probing (BOP). A multivariate analysis was also carried out to determine the degree of responsibility of the different risk factors, such as age, gender, being a smoker and the years of that habit duration, in relation to the extent and severity of the periodontal disease . Results: Twenty-nine per cent of women and fourty percent of men were smokers. The periodontal variables in the groups of S and NS behaved in the following way: PD for NS 4.19 (± 0.67), and for S 5.37 (±0.64) ; AL for NS 3.43 (±1.28), and for S 4.30 (±1.43); BOP for NS 41 (±23.76), and for S 43.28 (±23.56); OHI for NS 1.75 (±0.61), and for S 1.82 (±0.53); TP for NS 21.38 (±6.13), and for S 21.20 (±6.60) ; and M for NS 1.65 (±0.74), and for S 2.10 (±0.65). Conclusion: Stage II and III of periodontitis behaved similarly in both groups, but when we analysed stage IV of periodontitis, it was more prevalent in smokers, regardless of their age. When the population was stratified according to the age of the individuals, stage IV of periodontitis was more prevalent in older people who did not smoke and in young individuals under 40 who had the habit. PD, CAL and M periodontal variables were found with more severe values in the S group.

Introdução : O objetivo do presente estudo foi avaliar a gravidade da doença periodontal em uma população de adultos com doença gengival ou periodontal que atende no serviço de periodontia da Faculdade de Odontologia da Universidade Nacional de Rosario. Métodos : O estudo avaliou as condições periodontais em fumantes e não fumantes. A amostra foi composta por 400 indivíduos: 268 não fumantes (SN) e 132 fumantes ativos (E). A classificação das doenças gengivais e periodontais foi baseada nos critérios da American Association of Periodontology (2017), recrutando pacientes com diagnóstico de gengivite, estágio II, III e IV de periodontite. Cada uma dessas patologias foi relacionada às diferentes faixas etárias para avaliar os riscos de perda de inserção clínica. As variáveis periodontais estudadas foram: profundidade de sondagem (DP), nível de inserção (AL), número de dentes presentes (TP), índice de higiene bucal (IOH), mobilidade dentária (M) e sangramento à sondagem (BOP). Uma análise multivariada também foi realizada para determinar o grau de responsabilidade dos diferentes fatores de risco, como idade, gênero, ser fumante e os anos de duração desse hábito, em relação à extensão e gravidade da doença periodontal. Resultados : Vinte e nove por cento das mulheres e quarenta por cento dos homens eram fumantes. As variáveis periodontais nos grupos de S e NS comportaram-se da seguinte forma: PD para NS 4,19 (± 0,67) e para S 5,37 (± 0,64); AL para NS 3,43 (± 1,28) e para S 4,30 (± 1,43); BOP para NS 41 (± 23,76) e para S 43,28 (± 23,56); OHI para NS 1,75 (± 0,61) e para S 1,82 (± 0,53); TP para NS 21,38 (± 6,13) e para S 21,20 (± 6,60); e M para NS 1,65 (± 0,74) e para S 2,10 (± 0,65). Conclusão : Os estágios II e III da periodontite se comportaram de maneira semelhante nos dois grupos, mas quando analisamos o estágio IV da periodontite, esta foi mais prevalente em fumantes, independentemente de sua idade. Quando a população foi estratificada de acordo com a idade dos indivíduos, o estágio IV da periodontite foi mais prevalente em pessoas idosas que não fumavam e em indivíduos jovens com menos de 40 anos que tinham o hábito. As variáveis periodontais PD, CAL e M foram encontradas com valores mais severos no grupo S.

Directriz sobre el cuidado de la salud oral en adolescentes / Guideline for oral health in adolescents

Promover la adecuada comprensión de la prevención primaria en salud oral dirigida hacia los adolescentes debería ser una parte crucial de la odontopediatría. Estos pacientes constituyen un grupo de riesgo, ya que por la etapa en que se encuentran demandan atención odontológica especializada. Empero, las medidas preventivas para mantener la salud oral dirigidas hacia este colectivo no han sido impulsadas de manera prioritaria. Por lo que los profesionales de la salud oral que se encargan de la atención de adolescentes deben garantizar que este grupo de la población tenga un óptimo nivel de atención. En este artículo se determinan las pautas sobre cómo mantener el cuidado de la salud oral en adolescentes (AU)
