Algumas más oclusões exigem do ortodontista capacidade de diagnóstico para decidir pela melhor maneira de tratar o paciente. O objetivo dos autores deste artigo foi apresentar casos clínicos e discutir alguns elementos de diagnóstico utilizados na elaboração do plano de tratamento, auxiliando na decisão de extrair dentes. Foi dada ênfase em cada elemento de diagnóstico: aspectos relacionados à cooperação, discrepância de modelo, discrepância cefalométrica e perfil facial, idade esquelética (crescimento) e relações anteroposteriores, assimetrias dentárias, padrão facial e patologias. Sugere-se que a associação dos aspectos citados é importante para a decisão correta. Todavia, algumas vezes, uma característica, por si só, pode definir o plano de tratamento.; Certain malocclusions require orthodontists to be capable of establishing a diagnosis in order to determine the best approach to treatment. The purpose of this article was to present clinical cases and discuss some diagnostic elements used in drawing up a treatment plan to support tooth extraction. All diagnostic elements have been highlighted: Issues concerning compliance, model discrepancy, cephalometric discrepancy and facial profile, skeletal age (growth) and anteroposterior relationships...

Background: Preventing ridge collapse with the extraction of maxillary anterior teeth is vital to an esthetic restorative result. Several regenerative techniques are available and are used for socket preservation. The aim of this study is to analyze by clinical parameters the use of acellular dermal matrix (ADM) and anorganic bovine bone matrix (ABM) with synthetic cell-binding peptide P-15 to preserve alveolar bone after tooth extraction. Methods: Eighteen patients in need of extraction of maxillary anterior teeth were selected and randomly assigned to the test group (ADM plus ABM/P-15) or the control group (ADM only). Clinical measurements were recorded initially and at 6 months after ridge-preservation procedures. Results: In the clinical measurements (external vertical palatal measurement [EVPM], external vertical buccal measurement [EVBM], and alveolar horizontal measurement [AHM]) the statistical analysis showed no difference between test and control groups initially and at 6 months. The intragroup analysis, after 6 months, showed a statistically significant reduction in the measurements for both groups. In the comparison between the two groups, the differences in the test group were as follows: EVPM = 0.83 +/- 1.53 mm; EVBM = 1.20 +/- 2.02 mm; and AHM = 2.53 +/- 1.81 mm. The differences in the control group were as follows: EVPM = 0.87 +/- 1.13 mm; EVBM = 1.50 +/- 1.15 mm; and AHM = 3.40 +/- 1.39 mm. The differences in EVPM and EVBM were not statistically significant; however...

Aim: To evaluate the influence of the presence of both adjacent teeth on the level of alveolar bony crest at sites where implants were installed into the socket immediately after tooth extraction. Material and methods: Six Labrador dogs were used. Extractions of all teeth from the second premolar to the first molar were performed in the right side of the mandible, after full-thickness flap elevation. In the left side of the mandible, an endodontic treatment of the mesial root of the third and fourth premolars was performed. Full-thickness flaps were elevated, the teeth hemisected, and the distal roots removed. Immediately after, implants were bilaterally installed with the margin flush to the buccal bony crest. The implants were placed in the center of the alveolus at the third premolars and toward the lingual bony plate of the alveolus at the fourth premolars. After 3 months of healing, the animals were euthanized. Results: All implants were integrated in mature bone. More bone resorption was observed at the test compared to the control sites. At the buccal aspect, a resorption of 2.8 +/- 0.5 and 1.6 +/- 0.4 mm at the third premolars and of 2.4 +/- 0.6 and 0.8 +/- 0.7 mm at the fourth premolars were found, at the test and control sites...

O objetivo deste trabalho foi investigar a influência do enxerto ósseo autógeno particulado no processo de reparo do alvéolo dental de ratos Wistar após exodontia. Os animais foram divididos em grupos controle e experimental. Os ratos controles foram submetidos à intervenção cirúrgica para exodontia do incisivo superior direito apenas, enquanto nos ratos experimentais foram realizadas a exodontia e enxertia óssea no alvéolo dental. A eutanásia dos ratos foi realizada no 5o, 15o, 21o e 28o dias de pós-operatório. As amostras obtidas foram processadas para análise histológica. A densidade de área ocupada por osso foi quantificada por um método de contagem diferencial de pontos e com auxílio de um programa de imagens. Os resultados mostraram que a densidade de área preenchida por tecido ósseo não apresentou diferenças estatísticas em nenhum dos tempos pós-operatórios nos grupos analisados. Concluiu-se que o enxerto ósseo autógeno não promoveu um aumento significativo da neoformação óssea no alvéolo dental após exodontia.; After tooth extraction a continuous bone resorption of the alveolar process is observed in the maxilla and in the mandible. The unfavorable anatomy of the reabsorbed bone ridge limits the rehabilitation of the edentulous area with prostheses over dental implants. Filling the dental alveolus after the exodontia with bone grafts and/or biomaterials is a procedure that tries to delay the physiologic resorption of the alveolar process and stimulates bone formation. The aim of this study is to investigate the influence of the particulated autogenous bone graft in the alveolar socket healing following tooth extraction in Rattus Norvegicus Albinus lineage Wistar. Sixty-seven male rats were used...

Introdução: A regeneração óssea guiada baseia-se no princípio de seletividade celular, utilizando membranas para impedir a migração de células indesejadas dos tecidos moles e guiar a proliferação de células osteogênicas. A MDA é um biomaterial que tem sido amplamente utilizado em procedimentos regenerativos periodontais, não somente por ser biocompatível, mas também pela sua capacidade reconstrutiva em proporcionar um aumento da faixa de tecido queratinizado. Em pesquisas recentes, foi demonstrado o envolvimento de uma cadeia de 15 aminoácidos do colágeno (P-15) na diferenciação celular de fibroblastos e osteoblastos. A associação de matriz óssea inorgânica bovina com o P-15 (MOI/P-15) tem apresentado bons resultados. O objetivo dessa pesquisa foi avaliar a eficácia da MDA associada à MOI/P-15 na preservação da crista alveolar após extração dentária em humanos. Metodologia: Foram selecionados 18 pacientes que necessitavam de exodontia de dentes anteriores da maxila com pelo menos dois dentes não contíguos. Foi adotado o modelo boca dividida. Após as extrações dentárias foram realizadas cirurgias regenerativas de preservação da crista alveolar utilizando MOI/P-15 (GT) em um alvéolo e o coágulo sanguíneo no outro alvéolo (GC). Após a inserção do substituto ósseo...

A exodontia é o procedimento cirúrgico odontológico bastante praticado pelo Cirurgião Dentista clínico geral e pelo especialista quando, por diversos motivos, o elemento dentário necessita ser avulsionado. Atualmente a literatura ressalta enfaticamente a importância da preservação do rebordo alveolar durante o planejamento cirúrgico da exodontia, no que tange ao uso de técnicas cirúrgicas minimamente traumáticas, bem como o tratamento dado ao alvéolo fresco. Este estudo caso controle verifica variações das dimensões alveolares horizontais em alvéolos de dentes homólogos anteriores superiores, onde se realizou a manobra de Chompret (controle) e alvéolos onde esta não foi realizada (teste), ao final de um intervalo de sete dias pós operatórios, e conclui que há uma alteração dimensional média de 6,2% em espessura na parte coronária do alvéolo (p=0,003), quando se faz a manobra, também conhecida por compressão alveolar bidigital pós exodontia. O paciente necessita e deve ser reabilitado para que possa, dentro dos limites protéticos, voltar a ter suas funções mastigatória, estética e dictiva restauradas, o que nos compromete a espoliar ao mínimo suas estruturas ósseas remanescentes.; Tooth extraction is a surgical dental procedure always performed by general dentists and specialists when a tooth requires extraction...

A terapia antiplaquetária dual, cada vez mais tem sido utilizada como uma forma de abordagem terapêutica em pacientes com doença arterial coronariana (DAC), e principalmente em portadores de stents farmacológicos. Drogas antiplaquetárias, quando associadas, aumentam o risco de sangramento, isto faz com que muitos profissionais recomendem a suspensão da medicação antes de qualquer procedimento cirúrgico odontológico, entretanto, a suspensão desta terapia expõe os pacientes portadores de stent coronariano à riscos adversos de eventos trombóticos. Por consequência, permanece desafiador e controverso o manejo odontológico cirúrgico de pacientes coronariopatas em uso de terapia antiplaquetária dual. Diante disso, foi realizado uma pesquisa clínica com o objetivo de avaliar quantitativamente o sangramento trans-operatório de extração dentária de pacientes em uso de terapia antiplaquetária dual (AAS + clopidogrel). Este estudo caso-controle, incluiu 38 pacientes com DAC sob terapia antiplaquetária dual com AAS e clopidogrel (grupo de estudo = GE) e 35 pacientes com doença cardiovascular sem nenhum uso de medicação antiplaquetária (grupo controle = GC), ambos com indicação de extração dentária. No dia do procedimento cirúrgico...

The influence of different non-resorbable suture materials on the healing of tooth extraction wounds was examined in 120 adult male albino rats. Nylon gave the best biological results for healing of the mucosa and dental socket. Silk and cotton produced considerable delay of socket healing. Healing was only mildly delayed by polyester suture, with a short moderate inflammatory reaction at the initial stage.

The interference of a blood clot in the first postoperative hours of dental extraction wounds was studied in rats. Sixty male albino rats were divided into two groups: Group I, immediately after extraction of right maxillary incisor the gingival mucosa was approximated and sutured; Group II, after 6 to 8 minutes postoperatively the blood clot was removed with saline irrigation and absorbent paper cones. The mucosa was then approximated and sutured. Six animals in each group were sacrificed after 12 hours, 1, 4, 7 and 10 days. There was a profound delay in healing in Group II since, although a new blood clot was later formed, it was not organized. The quality and the constitution, maintenance and retraction of the clot are the regulating factors in connective tissue formation during alveolar healing.

The aim of this study was to evaluate the expression of osteocalcin protein during the alveolar bone healing process in rats. Twenty four rats were used in this study and, after anesthetic induction, they had their right upper incisors extracted. At 7, 14, 21 and 28 days after the tooth extraction, the animals were injected 4% formaldehyde. The histological tissue pieces were colored in hematoxilin and eosin and the immunohistochemistry reaction for osteocalcin was performed. At seven days lesser neoformed trabeculae bone and a small quantity of osteocalcin labeling were observed. At 14 and 21 days a larger quantity of neoformed trabeculae bone and higher osteocalcin values were detected. At 28 days the largest quantity of neoformed trabeculae bone and a decrease on the amount of osteocalcin immunolabelling were noticed. According to our results and considering the limits of the present study it is possible to conclude that a greater osteocalcin expression is observed at 14 and 21 days postoperatively, characterizing the periods when intense mineralization of the bone tissue occurs during the alveolar bone healing process.

Aim: To evaluate the influence of deproteinized bovine bone mineral in conjunction with a collagen membrane, at implants installed into sockets in a lingual position immediately after tooth extraction, and presenting initial horizontal residual buccal defects <2 mm. Material and methods: The pulp tissue of the mesial roots of 4P4 was removed in six Labrador dogs, and the root canals were filled with gutta-percha and cement. Flaps were elevated, and the buccal and lingual alveolar bony plates were exposed. The premolars were hemi-sectioned, and the distal roots were removed. Implants were installed in a lingual position and with the margin flush with the buccal bony crest. After installation, defects resulted at about 1.7 mm in width at the buccal aspects, both at the test and control sites. Only in the left site (test), deproteinized bovine bone mineral (DBBM) particles were placed into the defect concomitantly with the placement of a collagen membrane. A non-submerged healing was allowed. Results: After 3 months of healing, one implant was found not integrated and was excluded from the analysis together with the contralateral control implant. All remaining implants were integrated into mature bone. The bony crest was located at the same level of the implant shoulder...

PURPOSE: To evaluate the antioxidant and antiperoxidative effects of oil mixes of high ratio Omega-9:Omega-6 and low ratio Omega-6:Omega-3 in the third day after tooth extraction in rats. METHODS: Thirty-two male Wistar rats (270-310g) were randomly distributed in two groups: Control (n=24) and Test (n=8). Control group was divided into three subgroups (n=8): G1: Sham-Saline; G2: Saline; G3: Isolipid. G1 and G2 animals received NaCl 0.9% while G3 rats were treated with an isolipid mixture (alpha-linolenic acid - ALA) containing -6/-3 oils (8:1 ratio) and-9/-6 (0.4:1 ratio). Test group animals (G4) received oily mixtures (alpha-linolenic acid - ALA, docosahexaenoic acid - DHA, eicosapentaenoic acid - EPA) of -6/-3 (1.4:1 ratio) and -9/-6 (3.4:1 ratio). Saline and oils were administered by gavage during four days before and three days after first mandibular molar extraction. Following, samples (arterial blood and alveolar mucosa) were collected for glutathione (GSH) and thiobarbituric acid reactive substances (TBARS) assays. RESULTS: Oil mixes induced a significant decrease in GSH and TBARS tissue and plasma concentrations in the third day post-surgery. CONCLUSION: Gavage administration of oil mixes of high ratio Omega-9:Omega-6 and low ratio Omega-6:Omega-3 after molar extraction in rats induces a significant decrease in lipid peroxidation.

The purpose of the present study was to investigate if diclofenac administration interferes with the time course of alveolar wound healing in rats. Forty-two Wistar rats were used, 21 rats received 10 mg/kg/day of diclofenac one day before and 4 days after extraction of the right maxillary incisors and 21 rats received saline. The animals were sacrificed 7, 14 and 21 days after tooth extraction. Progressive new bone formation and a decrease in the volume fraction of blood clot and connective tissue from 1 to 3 weeks after tooth extraction was quantified using the histometric point-counting method. Diclofenac treatment caused a significant delay in new bone formation in association with an impairment of blood clot remission/organization.

OBJECTIVE: To compare, through computed tomography, alveolar bone thickness changes at the maxillary incisors area during orthodontic treatment with and without tooth extraction. METHODS: Twelve patients were evaluated. They were divided into 2 groups: G1 - 6 patients treated with extraction of right and left maxillary first premolars, with mean initial age of 15.83 years and mean treatment length of 2.53 years; G2 - 6 patients treated without extraction, with mean initial age of 18.26 years and mean treatment length of 2.39 years. Computed tomographies, lateral cephalograms and periapical radiographs were used at the beginning of the treatment (T1) and 18 months after the treatment had started (T2). Extraction space closure occurred in the extraction cases. Intragroup and intergroup comparisons were performed by dependent and independent t test, respectively. RESULTS: In G1, the central incisor was retracted and uprighted, while in G2 this tooth showed vestibularization. Additionally, G1 presented a higher increase of labial alveolar bone thickness at the cervical third in comparison with G2. The incidence of root resorption did not present significant differences between groups. CONCLUSION: There were no changes in alveolar bone thickness when extraction and nonextraction cases were compared...

ObjectiveTo compare the sequential healing at immediately loaded implants installed in a healed alveolar bony ridge or immediately after tooth extraction.Material and methodsIn the mandible of 12 dogs, the second premolars were extracted. After 3months, the mesial roots of the third premolars were endodontically treated and the distal roots extracted. Implants were placed immediately into the extraction sockets (test) and in the second premolar region (control). Crowns were applied at the second and third maxillary premolars, and healing abutments of appropriate length were applied at both implants placed in the mandible and adapted to allow occlusal contacts with the crowns in the maxilla. The time of surgery and time of sacrifices were planned in such a way to obtain biopsies representing the healing after 1 and 2weeks and 1 and 3months. Ground sections were prepared for histological analyses.ResultsAt the control sites, a resorption of the buccal bone of 1mm was found after 1week and remained stable thereafter. At the test sites, the resorption was 0.4mm at 1-week period and further loss was observed after 1month. The height of the peri-implant soft tissue was 3.8mm both at test and control sites. Higher values of mineralized bone-to-implant contact and bone density were seen at the controls compared with the test sites. The differences...

The gauging of unerupted deciduous canine teeth occurs in approximately one in three children in some areas of Uganda. It is believed that such teeth are ‘maggots’ that cause fever, diarrohea and vomiting. Traditional healers use knitting needles, bicycle spokes, scissors or broken glass to extract the teeth. Post-ebino extraction complications include septicaemia, anaemia, difficulties in feeding and pain. Some children require hospitalization. Health is further compromised when multiple ebino extractions occur at one time, increasing the risk of human immunodeficiency virus/acquired immunodeficiency syndrome transmission. An ebino education initiative was developed in the southwest Ugandan province of Rukungiri, based on the findings of five community-based focus group discussions. The initiative involved role-plays, didactic presentations and discussion/debate workshops to 23 women's groups in 15 communities (total number of women exposed = 1874). After 1.5 years of the programme's inception, community awareness of the scientific causes and alternatives to ebino extractions had increased (as gauged by follow-up focus group discussion findings) and the number of hospital admissions for traditional tooth extraction complications had reduced. The appropriateness of the model in exploring and addressing ebino extraction beliefs and attitudes is discussed...

OBJECTIVES: This study was conducted to determine the changes in blood pressure and the pulse rate of patients with controlled hypertension having dental extraction under local anaesthesia utilizing 2% lignocaine with adrenaline, and to evaluate whether these changes in blood pressure were are attributable to addition of adrenaline. METHODS: This prospective study was carried out in 33 consecutive hypertensive patients who presented at the exodontia clinic of the Department of Oral and Maxillofacial Surgery, Lagos University Teaching Hospital (LUTH), Idi-Araba, Lagos, from December 2004 to August 2005 for intra-alveolar tooth extraction. Patients were randomly allocated to two groups according to the type of anaesthetic solution employed. Group A had tooth extraction done under 2% lignocaine with 1:80 000 adrenaline while group B had tooth extraction done under 2% lignocaine without vasoconstrictor (plain lignocaine). One tooth was extracted from each patient. Blood pressure and pulse rate measurements were recorded in the waiting room before surgery, in the surgery after local anaesthetic injection, during tooth extraction and 15 minutes after tooth extraction. RESULTS: The sample consisted of 20 females and 13 males age range 24 to 75 years (mean ± SD = 50.1 ± 11.7 years). There was no statistically significant difference between the systolic and diastolic blood pressure and pulse rate in the two groups after administration oflocal anaesthesia. However...
