RESUMEN

Pericoronitis is a common dental condition involving the inflammation of soft tissues around a partially erupted wisdom tooth, typically the lower third molars. It is most frequently diagnosed in young adults aged 20-29, with a higher prevalence in women. The condition often results from the accumulation of bacteria and food debris under the operculum, leading to infection and inflammation. Common symptoms include localized pain, gum swelling, trismus, and sometimes pus discharge. This study aims to discuss the types of clinical management of pericoronitis of the lower third molar as described in the literatureTooth extraction eliminates the source of inflammation, providing long-term relief but carries a higher risk of inferior alveolar nerve damage and greater postoperative discomfort compared to other methods.This minimally invasive procedure removes the gingival cap to prevent food and bacteria accumulation. It is suitable for patients with good oral hygiene and proper tooth angulation. Electrosurgery and laser methods reduce bleeding and swelling but have contraindications. Coronectomy, an alternative to extraction, avoids nerve damage by leaving the roots in place. Suitable for non-carious, pathology-free teeth, it shows lower risk of sensory disturbances and postoperative complications, though root migration may occur. Pericoronitis requires personalized treatment based on patient condition and tooth positioning. Thorough diagnostics and tailored approaches are crucial for effective management and improved outcomes.

RESUMEN

A bacterial infection is typically the source of gingivitis, a non-destructive condition that produces gum inflammation. Unlike chronic lesions, which have well-defined features and a gradual onset, acute lesions are unpleasant. Usually, the first symptoms are bleeding, swollen, and red gums. If gingivitis is not treated, it can lead to periodontitis, a more serious condition where the gums separate from the teeth. It seems that gingival disease-induced inflammation is a necessary condition for the breakdown of connective tissue attachment apical to the cementoenamel junction (CEJ). This may result in damage to the bone and soft tissue that support the teeth, leading to loosening and unstable teeth, and if the infection worsens, eventual tooth loss may occur. While one of the most prevalent inflammatory diseases in humans is plaque-induced gingivitis, there are several less common but frequently very significant non-plaque-induced gingival illnesses. Maintaining regular dental hygiene can help prevent gingivitis and make it reversible. Non-plaque-induced gingival lesions might be pathologic alterations restricted to gingival tissues, but they are also frequent signs of systemic disorders. Diagnosing patients with these lesions and creating treatment regimens for them must be the aim of the therapy.

RESUMEN

BACKGROUND: Pericoronitis, an inflammation near wisdom teeth, often occurs when they are partially emerged, especially in the lower jaw. Commonly, the gingiva partially envelops the tooth. Treatments vary from gingival surgery to extraction. This study assessed the efficacy of a mouthwash with Chlorhexidine, Benzydamine, Nanosilver, Amoxicillin, and Metronidazole for pain reduction and enhancement of maximum mouth opening in acute pericoronitis cases. MATERIALS AND METHODS: In this randomized controlled clinical trial conducted at the Gorgan Dental Faculty, 48 pericoronitis patients were randomized into two groups. The control group used a 0.12% chlorhexidine mouthwash, while the case group used a mouthwash containing Chlorhexidine, Benzydamine, Nanosilver, Amoxicillin, and Metronidazole. The study recorded Visual Analog Scale (VAS) scores for 7 days, and Maximum mouth opening (MMO) was measured at the start and after 7 days. The analysis was performed using SPSS v20. RESULTS: In this study, we compared the effects of a combined mouthwash with those of a chlorhexidine mouthwash on pericoronitis in 48 patients, with an average age of 21.56 years. No significant difference in pain reduction was observed between the groups; however, both groups exhibited decreased pain and improved MMO post-treatment. The gender distribution was balanced across both groups. CONCLUSION: The results indicate that both chlorhexidine mouthwash and combined mouthwash significantly improved maximum mouth opening. Nonetheless, there were no notable differences in efficacy between the two groups. These findings suggest that these mouthwashes may be beneficial for oral hygiene, warranting further in-depth research. TRIAL REGISTRATION: Registered on 12/03/2023, registration number IRCT20230104057046N1.

RESUMEN

INTRODUCTION: Pericoronitis of wisdom teeth along the jaw diffusion may be a rare diffusion pathway, which can cause osteomyelitis and maxillofacial space infection serious complications. PRESENTATION OF CASE: A 62-years-old male patient presented with swelling and discomfort of the right cheek for more than 1 year. The patient was previously healthy and denied various systemic medical histories. The patient's face was asymmetric, the right cheek was swollen, and the depressed edema was seen on the surface of the masseter area of the right parotid gland. Based on the preoperative cone-beam computed tomography (CBCT) imaging results, the initial diagnosis was: centralized osteomyelitis of the jaws. The surgical plan was minimally invasive extraction 48 and localized debridement of the lesion area. After three months of follow-up, the patient's symptoms were significantly improved without recurrence. DISCUSSION: Pericoronitis of wisdom teeth along the jaw diffusion is a rare diffusion pathway, which can lead to secondary jaw osteomyelitis, the treatment of which consists of lesion debridement, dead bone curettage and antibiotic therapy. CONCLUSION: Through literature review and summary of the diagnosis and treatment process of this case, such cases should be diagnosed as early as possible and conservative treatment should be actively used to avoid the occurrence of complications. In addition, the special diffusion pathway of this case may provide a new theoretical basis for the source of infection of central jaw osteomyelitis.

RESUMEN

PURPOSE: The factors related to pericoronitis severity are unclear, and this study aimed to address this knowledge gap. MATERIALS AND METHODS: In total, 113 patients with pericoronitis were included, and their demographic, clinical, and radiographic characteristics were recorded. The Patient-Clinician Pericoronitis Classification was used to score and categorize the severity of pericoronitis. Statistical analysis was conducted to examine the participants' characteristics, validity of the Patient-Clinician Pericoronitis Classification, and risk factors associated with the severity of pericoronitis. RESULTS: The demographic, clinical, and radiographic characteristics of males and females were similar, except for Winter's classification, pain, and intraoral swelling. The constructive validity of the Patient-Clinician Pericoronitis Classification was confirmed with three latent factors, including infection level, patient discomfort, and social interference. Ordinal logistic multivariate regression analysis revealed that upper respiratory tract infection was the sole risk factor associated with pericoronitis severity in males (odds ratio = 4.838). In females, pericoronitis on the right side (odds ratio = 2.486), distal radiolucency (odds ratio = 5.203), and menstruation (odds ratio = 3.416) were significant risk factors. CONCLUSION: This study demonstrated the constructive validity of the Patient-Clinician Pericoronitis Classification. Among females, pericoronitis in mandibular third molars on the right side with radiolucency in menstruating individuals was more severe. In males, upper respiratory tract infection was the sole risk factor associated with pericoronitis severity. CLINICAL RELEVANCE: Individuals with risk factors should be aware of severe pericoronitis in the coming future.

RESUMEN

Introduction: Timely and effective treatments of pericoronitis are very important. We aimed to evaluate the role of ornidazole in the treatment of pericoronitis, to provide insights for clinical pericoronitis treatment. Material and methods: The PubMed, Clinical trials, EMBASE, Science Direct, Cochrane Library, China National Knowledge Infrastructure (CNKI), Weipu and Wanfang databases were searched to find randomized controlled trials (RCTs) of ornidazole in the treatment of pericoronitis from the establishment of the database to March 15, 2023. Review Manager 5.3 software was used for meta-analysis. Results: A total of 16 RCTs involving 2004 patients were included. The results of the meta-analysis showed that the effective rate of ornidazole treatment was significantly higher than that of the routine treatment group (RR = 1.22, 95% CI (1.15, 1.29), p < 0.001). Ornidazole treatment was beneficial to reduce the oral bacterial density (MD = -26.13, 95% CI (-32.08, -21.51)), time to pain disappearance (MD = -0.64, 95% CI (-0.92, -0.17)) and time to disappearance of redness and swelling of the teeth crown (MD = -1.45, 95% CI (-2.43, -1.01)) compared to the routine treatment (all p = 0.05). No publication bias was found by the funnel plots and Egger test (p = 0.206). Conclusions: Ornidazole is effective in the treatment of pericoronitis, with more advantages. Still, the effects and safety of ornidazole in the treatment of pericoronitis need to be evaluated by more high-quality RCTs with larger sample sizes.

RESUMEN

Background: Pericoronitis is a common pathological condition related to mandibular third molar teeth (wisdom teeth). It is an inflammation of the soft tissue surrounding the crown of an erupted or partially erupted tooth that causes pain and discomfort. We aimed to investigate the relation between third molar impaction types and pericoronitis. Methods: This cross-sectional study assessed 60 patients referred to the Oral and Maxillofacial Surgery Department of Mashhad Dental School, Mashhad University of Medical Sciences, Mashhad, Iran in 2022 for totally and partially impacted mandibular third molar tooth surgery with pericoronitis. Their demographic data, including age and gender, was recorded. The impacted tooth's side and the symptoms of pericoronitis were identified using clinical examination and panoramic radiography imaging, based on the Pell & Gregory criteria and Peterson's classification. Third-molar tooth surgery was performed according to standard protocol. Patients' data were recorded and were analyzed using Excel 2019 and SPSS ver 21. Results: The prevalence of pericoronitis symptoms in women was higher than in men (P< 0.001). The Class B type of third molar teeth impaction had a relation with the majority of pericoronitis cases (P< 0.001). Pericoronitis and systemic symptoms were more likely to occur in Class II than in Class I type of third molar teeth impaction (P< 0.001). The most frequent kind of impaction linked to pericoronitis and systemic symptoms such as malaise was mesio-angular (P< 0.001). The symptoms of pericoronitis were substantially correlated with smoking (P< 0.001). Conclusion: Class B, Class II, and mesio-angular types of third molar impaction are linked with a higher risk of pericoronitis. This information might help in the early diagnosis and management of pericoronitis in patients with impacted third molar teeth.

RESUMEN

Background: There are limited number of studies about the lasers used for the treatment of pericoronitis infection. Aim: To compare the Er, Cr:YSGG laser and diode laser applications clinically in the treatment of pericoronitis infection. Patients and Methods: Sixty patients with pericoronitis infection were divided into three groups using block randomization: Er, Cr:YSGG + antibiotic group, n = 20 (mean age: 24.20 ± 6.13; 14 females, 6 males); diode group + antibiotic, n = 20 (mean age: 23.45 ± 2.96; 14 females, 6 males); and antibiotic, n = 20 (mean age: 22.45 ± 3.02; 11 females, 9 males). In addition, laser application was performed for patients in the Er, Cr:YSGG and diode laser groups on the 1st and 2nd days until the extraction day. Tooth extractions were performed on the 3rd day for all patients. Patients' pain (with visual analog scale [VAS]), lymphadenopathy, and local edema were clinically evaluated in the first 3 days and on the 7th day of treatment. Results: Pain score on the 2nd day of treatment was determined to be significantly lower in the Er, Cr:YSGG + antibiotic laser group as compared with the other two groups (P = 0.019). Although regression of lymphadenopathy on the 3rd day was highest (P = 0.025) in the Er, Cr:YSGG group, there was no significant difference between the groups regarding local edema. Conclusion: Er, Cr:YSGG laser improved the healing process in the treatment of pericoronitis and made an important contribution to the treatment.

RESUMEN

Paradental cyst is an odontogenic cyst associated with pericoronitis in partly erupted mandibular third molars. It is an inflammatory cyst common among the mandibular molars. The cyst is most commonly seen on the distal or distobuccal aspect of the third molars. The angle of tooth and food impaction has been postulated to be responsible for the development of the cyst in third molars. The source of the epithelium has been reported as reduced enamel epithelium. The paradental cyst is frequently misdiagnosed as a radicular cyst or dentigerous cyst. We report a case of paradental cyst in a patient with partially erupted mandibular third molar with food impaction and resulting hyaline ring granuloma.

RESUMEN

OBJECTIVE: This cross-sectional study evaluated the number and characteristics of third molars extracted in a single visit in primary care and their associations with patient's age and sex and operator's experience. MATERIALS AND METHODS: The data included all appointments where routine and surgical extractions of third molars were performed in 2016 in primary care of the City of Helsinki. Statistics included χ2 and Mann-Whitney U tests, and binomial logistic regression. RESULTS: In total of 10,894 appointments, the number of extracted third molars was 12,728, yielding an average of 1.2 third molars per visit. Mean age of patients (55% women, 45% men) at extraction was 32.2 years (range 12 - 97 years). Most appointments (83.7%, n = 9,118) comprised extraction of one, 15.8% two, 0.4% three, and 0.1% four third molars. Number of teeth extracted at a time did not differ by sex. Increasing age was associated with a reduction in the likelihood of several third molar extractions in a visit (OR 0.96; 95% confidence interval (CI) 0.96-0.97). Multiple third molars were extracted significantly more likely if the operator was experienced (OR 2.32; 95%CI 1.90-2.84). Multiple extractions were also associated with the mandible, operative extractions, unerupted teeth and caries. CONCLUSIONS: Third molars were typically extracted one at a time. In health care units, it is appropriate to consider extraction of several third molars in a single visit, if need for extraction of other third molars exist. Concentrating the extractions of younger patients on experienced operators would reduce the number of patients' visits.

RESUMEN

BACKGROUND: Mandibular third molar (M3M) removal and the management of postoperative complications represent a common matter of interest in oral and maxillofacial surgery. Pain represents a great symptom for patients affected by pericoronitis and it is the most common indication for third molar removal. The aim of the present article is to search for patterns of pre-operative pain in patients before undergoing third molar surgery and to test for a relation between some patterns of symptoms, such as pain intensity, site of symptomatic tooth, and referred area of pain. METHODS: This retrospective observational study enrolled a total of 86 patients, aged (mean ± SD) 34.54 ± 13.62 years (range 17-78 years), scheduled for outpatient third molar extraction at the Oral Surgery School, Department of Medical Biotechnologies, Policlinico "Le Scotte", University of Siena. Pericoronitis and pain were the symptoms of the patients and the indication of extraction. Inclusion criteria were the presence of partially impacted third molars, confirmed with a preoperative panoramic radiograph, and preoperative pain. Exclusion criteria were known neurological disease (such as previous trigeminal or facial nerve injuries), impaired communicative or cognitive disease, diagnosed diabetes mellitus, and oral surgical intervention within 30 days before data collection. Patients were visited and asked to answer a morphometric analytic questionnaire about their perception of pain referred to the third molar. Analyses were performed on statistical evaluation on age, age ranges, patient gender, prior third molar extraction, site of pericoronitis, pain score (1-10), and pain area. Two-tailed p values of less than 0.05 were considered significant if not otherwise specified. RESULTS: No correlations were found between age, gender, previous extraction, tooth site (maxillar on mandible), pain score, and pain area. Patterns of third molar pericoronitis pain among 86 patients were reported. A significant correlation was found between pain score and pain area (p = 0.0111, rs = 0.3131). CONCLUSIONS: Pain intensity has indeed some kind of responsibility in determining the orofacial distribution of pain. The pain area referral patterns of the present article could be considered as a pain model resulting from the pericoronitis of maxillar and mandibular third molars.

RESUMEN

Cervical necrotizing fasciitis is a very rare complication of a bacterial infection that can have a dental cause. This type of infection typically affects fascial plane, which has a poor blood supply and can affect soft tissue and cervical fascia and can spread quickly causing infection of mediastinum. Initially, in the first stage, the overlying tissues are unaffected, and this can delay diagnosis and surgical intervention. Incidence in children is extremely rare and can be frequently associated with various other general pathologies that decrease the immune system response. We present a case of a young 12-year-old boy diagnosed with this type of infection in the head and neck as a complication of a second inferior molar pericoronitis. The treatment and the management of the case was difficult not only due to the presence of the infection but also because of the prolonged intubation.

RESUMEN

BACKGROUND: Dental infections, which are the main cause of tooth loss, are known to be caused by bacteria. However, recent research suggests that other organisms, such as viruses, may also play a role. In this study, we aim to detect the presence of human papillomavirus (HPV)-16 and assess its prevalence in tissues infected with various dental infections, including aggressive and chronic periodontitis, pericoronitis, and periapical infection, as well as healthy gingival tissues, saliva, and gingival crevicular fluid, for comparison. METHODS: A cross-sectional study including 124 adult healthy patients presenting with dental infections requiring dental extractions were conducted to assess the prevalence of HPV-16 in saliva, infected, and healthy tissues using quantitative polymerase chain reaction (PCR) tests. Samples were collected and a categorical scale was used for the prevalence. Statistical analyses were performed using Chi-square for the prevalence of HPV-16. RESULTS: Among the HPV-16-positive PCR cases, the prevalence of HPV-16 was highest in periapical infection tissues as compared to chronic periodontitis, aggressive periodontitis, pericoronitis, and control tissues. CONCLUSION: The prevalence of HPV-16 in periapical infection samples was the highest among the studied dental infection samples. Thus, a primary conclusion can be drawn about the presence of an association between HPV-16 and the occurrence of periapical infection.

RESUMEN

Background: The aim of this systematic review was to analyse the published literature on dental infections leading to hospitalisations in Australia. It was hoped that understanding the patterns and trends would form a basis for improved preventive and management policies. Methods: An electronic search was performed using Web of Science, Medline via Ovid and Google Scholar. Inclusion and exclusion criteria were applied. The included studies were analysed for demographics, aetiology, management, length of hospital stay and outcome of dental infections requiring hospitalisation. Results: Nine retrospective studies were eligible for inclusion. A total of 2196 cases of dental infections leading to hospitalisations were reported, with a male predominance (55-67%). Mental health issues, illicit substance abuse and immunosuppression were the main associated comorbidities (up to 58%). Dental caries (59-90%) and pericoronitis (10-19%) were the leading causes of dental infections. Empirical antibiotics were utilised in up to 75% of cases prior to hospital presentation. Six mortalities were reported. Conclusions: The available published data show that dental infection is a significant public health problem. However, only general conclusions were possible due to the variably small sample size and data collection that was inconsistent and incomplete across studies. Improved data collection is required to develop policies for prevention and management.

RESUMEN

Background: Acute pericoronitis (AP) is a common cause of odontogenic toothache. Pain significantly affects the structure and function of the brain, but alterations in spontaneous brain activity in patients with AP are unclear. Purpose: To apply the amplitude of low-frequency fluctuations (ALFF) method in resting-state functional magnetic resonance imaging to investigate altered spontaneous brain activity characteristics in patients with AP in different frequency bands (typical, slow-4, and slow-5 bands) and assess their correlation with clinical scores. Patients and Methods: Thirty-four right-handed patients with AP and 31 healthy controls (HC), matched for age, sex, education, and right-handedness, were enrolled. All subjects underwent resting-state functional magnetic resonance imaging. DPABI software was used for data preprocessing and extracting the ALFF values in different frequency bands. Subsequently, differences in ALFF values in the three bands were compared between the two groups. Correlation between ALFF values in the differential brain regions and clinical scores was assessed. Results: In the typical band, ALFF values were higher in the left insula, left superior occipital gyrus, left inferior parietal lobule, left posterior cerebellar lobule, and right postcentral gyrus in the AP than in the HC group. In the slow-4 band, ALFF values in the left superior occipital gyrus, right superior occipital gyrus, and right middle occipital gyrus were higher, and those in the right cingulate gyrus and right superior temporal gyrus were lower in the AP than in the HC group. In the slow-5 band, the ALFF values in the left insula and left superior occipital gyrus were higher in the AP than in the HC group. The ALFF values of the typical bands in the left insula, left inferior parietal lobule, and right postcentral gyrus correlated negatively, those of the slow-4 band in the right middle occipital gyrus correlated positively, and those of the slow-5 band in the left insula correlated negatively with the visual analogue scale score in the AP group. Conclusion: Our results suggested that the intrinsic brain activity of AP patients was abnormal and frequency-dependent. This provides new insights to explore the neurophysiological mechanisms of AP.

RESUMEN

Pericoronitis is a common disease that impacts the quality of life of individuals during the eruption of the third molars. Among the main clinical signs and symptoms reported were the presence of gingival operculum, pain, difficulty swallowing, and trismus with functional impairment. The present study shows a case report of pericoronitis treated with antimicrobial photodynamic therapy (aPDT), using a new oral formulation (INPI BR 1020170253902) of methylene blue. A female patient, 27 years old, presenting initial pericoronitis, had her pain, mouth opening, and swelling evaluated. She was submitted to a protocol of irrigation with sterile saline and photodynamic therapy using the new MB at 0.005% concentration and irradiation with low-intensity laser λ = 660 nm, 9 J per point, and radiant exposure of 318 J/cm2. The variables were evaluated on 4th day after aPDT. There was a 100% improvement in pain and an increase of 1,3 cm in mouth opening. There was no difference in the edema before and after aPDT using the new MB formula. Although the results are based on a single case report, suggest the hypothesis that aPDT using the new MB formula is an efficient therapy in the treatment of pain and trismus caused by the early stage of pericoronitis. Well-conducted randomized clinical trials are needed to compare this new formulation with conventional aPDT for further generalization of results.

RESUMEN

Se presenta el caso de un paciente joven inmunocompetente, con antecedente de tuberculosis pulmonar, que acude al hospital por un cuadro clínico subagudo de fiebre persistente, baja de peso, disnea y abolición del murmullo vesicular. La tomografía de tórax mostró un extenso empiema en hemitórax izquierdo. Se le toman muestras para detección de gérmenes comunes y se le colocan un tubo de drenaje torácico y se inicia antibioticoterapia. La prueba de MALDI-TOF MS identificó a Parvimonas micra, una bacteria anaerobia, comensal de la flora oral, asociado a periodontitis severa, escasamente reportado en empiema pleural, especialmente, en personas inmunocompetentes. En la evaluación odontológica se realizó el diagnóstico de gingivitis y pericoronaritis de la tercera molar. El paciente evolucionó favorablemente. Se sugiere que, en casos de empiemas pleurales subagudos o crónicos, se debe considerar, además de las micobacterias, como agente etiológico al Parvimonas micra, y optar por exámenes como MALDI-TOF MS o secuenciamiento del 16S rRNA, colocación de tubo de tórax, cobertura antibiótica empírica y evaluación odontológica.

We present the case of a young immunocompetent patient, with a history of pulmonary tuberculosis, who attended the hospital with a subacute clinical picture of persistent fever, weight loss, dyspnea and abolition of vesicular murmur. Chest CT scan showed an extensive empyema in the left hemithorax. Samples were taken for detection of common germs. Then, a chest drainage tube was placed and antibiotic therapy started. The MALDI-TOF MS test identified Parvimonas micra, an anaerobic bacterium, commensal to the oral flora, associated with severe periodontitis, but rarely reported in cases of pleural empyema, especially in immunocompetent patients. Gingivitis and pericoronaritis of the third molar were diagnosed during oral evaluation. The patient progressed favorably. Parvimonas micra should be considered as a possible etiological agent in cases of subacute or chronic pleural empyema, in addition to mycobacteria. Tests such as MALDI-TOF MS or 16S rRNA sequencing, chest tube placement, empirical antibiotic coverage and an adequate oral evaluation should be considered in these cases.
