RESUMEN
AIM: The aim of this study was to investigate the role of pyridoxal-5-phosphate (PLP) level on the oral health status as a predictive marker in patients with hypophosphatasia (HPP). MATERIALS AND METHODS: Throughout a systematic retrospective assessment both bone metabolism and oral health status were analyzed. The oral health status was assessed by the decayed/missing/filled teeth index (DMFT), clinical attachment level (CAL), probing pocket depth (PPD), and the periodontal screening index (PSI). RESULTS: A total of 48 HPP patients (81.3% female) with a mean age of 42.21 years was included in this retrospective study. The study population was divided into two groups using the mean PLP level (87 µg/l) as a cut-off. Patients with a PLP level ≥ 87 µg/l (n = 14) showed a significantly poorer oral health status regarding DMFT index, CAL, PPD and PSI compared to patients with a PLP level < 87 µg/l (n = 34). No significant group differences for tooth loss were found. CONCLUSION: The results of the present study indicate that the PLP level is a suitable diagnostic predictor for the oral health status in HPP patients. HPP patients with PLP levels ≥ 70 µg/l should be included into a regular dental preventive program. CLINICAL RELEVANCE: The oral health status in HPP and its correlation with laboratory parameters (i.e. PLP) has been understudied. For clinical practice, the findings of the present study clearly demonstrated that high PLP levels correlate with a worse oral health status in HPP patients. Therefore, these patients should receive an intensive dental treatment and/or inclusion in a strict maintenance program in a specialized dental practice/university hospital with a PLP level ≥ 70 µg/l.

BACKGROUND/AIMS: The COVID-19 (Coronavirus Disease-2019) pandemic confronted the global healthcare system with a variety of challenges. The pandemic and the associated lockdowns also had an impact on multiple medical disciplines (i.e. delay of surgery, change of hospital admissions). The aim of this study was to analyze the impact of the COVID-19 pandemic on mandible fracture patterns/distributions and circumstances in a German cranio-maxillofacial trauma center. MATERIALS AND METHODS: This retrospective study compared the mandible fracture patterns of patients in the PreCOVID (PC) era (February 2019-January 2020) with patients in the IntraCOVID (IC) era (February 2020-January 2021). In addition to baseline characteristics, the number/type of mandible fractures, location of the mandible fracture, circumstances leading to mandible fracture, and hospital admissions/treatments were analyzed. RESULTS: A total of 127 patients was included in this study. In the IC period, the absolute frequencies of mandible fractures decreased (PC = 72 vs. IC = 55). There were minor changes in the mandible fracture locations. An increase of concomitant facial soft tissue injuries (IC = 69.1% vs. PC = 58.3%), as well as higher rates of traumatic tooth loss (IC = 32.7% vs. PC = 22.2%), was observed. Regarding the causes/accidents leading to mandible fractures, there were significant increases in falls and significant decreases in sports accidents as well as interpersonal violence during the IC period. A significant increase in accidents at home and domestic violence during the COVID-19 pandemic, with a simultaneous decrease in weekend and night-time trauma leading to mandible fractures was observed. Furthermore, a significant increase in days from trauma to surgery was recorded. CONCLUSION: The COVID-19 pandemic had a significant impact on mandibular fracture patterns. The locations and types of mandibular fractures changed slightly. However, significant differences in the circumstances leading to mandible fractures (increased falls, decreased interpersonal violence) were recorded.

Background: Osteomyelitis is a serious entity that can occur in many different locations. Especially in the mandible, osteomyelitis can show different clinical courses, which differ clearly from other anatomical regions in terms of severity and treatment. Osteomyelitis in the mandible is often caused by mixed species of the oral cavity. A species causing subacute/chronic osteomyelitis can be actinomyces. Actinomycotic osteomyelitis of the jaw represents a diagnostic and treatment challenging disease. Conclusion: This article describes our perspective on the therapy pillars treating actinomycotic osteomyelitis. The rapid introduction of the two therapeutic elements (antibiosis/surgical therapy) is crucial regarding the outcome of this entity.
RESUMEN
BACKGROUND/AIM: The treatment of squamous cell carcinoma (SCC) in the oral cavity for operable patients usually consists of surgical tumor resection, unilateral or bilateral neck dissection and defect reconstruction. In addition to local flaps, multiple, particularly microsurgical, distant flaps have been developed, which are mainly considered state of the art reconstruction. However, depending on previous operations and individual patient factors, microsurgical reconstruction is sometimes not suitable. CASE REPORT: A 54-year-old male presented to the Department of Oral and Maxillofacial Surgery with leukoplakia-like changes in the area of the soft palate. Radiological and histopathological findings revealed SCC of the soft palate. Due to the patient's reduced general condition, pronounced vasosclerosis and the patient's negative opinion towards microsurgical reconstruction, the indication for tumor resection with simultaneous temporalis flap reconstruction was made. The temporalis flap showed sufficient healing throughout the follow up. CONCLUSION: For patients who are unsuitable for microsurgery (previous operations, radiation, patient's request), well-known local flaps such as the temporalis flap represent more than an alternative treatment for defect reconstruction. The temporalis flap is particularly suitable for defect reconstruction of the maxilla and palate due to its easy flap raising and low complication rates. This case report shows the step-by-step flap raising of temporalis flap for soft palate reconstruction.

BACKGROUND: The surgical removal of impacted third molars is considered a routine procedure for oral and maxillofacial surgeons. However, the distribution of impacted molars varies among different populations. A study into impaction patterns in the German population is currently not described. The aim of this retrospective study is to determine patterns of impacted third molars in a sample of German population, to identify gender and age specific differences as well as further risk factors for impacted molar extraction and to compare these results with other studies. MATERIALS AND METHODS: The clinical findings and digital panoramic radiographs of 84 patients with a total of 243 impacted third molars that had been subjected for tooth extraction, from January to September 2023, were collected and analyzed. All third molars were analyzed according to Winter´s angulation, Pell and Gregory Score of depth and relationship to ramus. Furthermore, inferior alveolar nerve and maxillary sinus proximity were identified through a newly developed risk score and an analysis of patient´s gender and age regarding impaction patterns was performed. RESULTS: No significant gender specific differences were found regarding the impaction patterns. Third molar angulations significantly differed regarding patient´s age (cut-off 26 years). In comparison, third molar depth, bone coverage, nerve approximity and angulation patterns differed from the results of other populations. CONCLUSION: The results of this study can serve as a baseline for further studies of third molar impactions in the German population to minimize perioperative complications in impacted third molar surgery.
RESUMEN
BACKGROUND: The surgical removal of impacted third molars is usually carried out by an oral/maxillofacial surgeon. Two specific risks of surgical removal of impacted third molars are oroantral communication (OAC) when extracting ââupper third molars and hypesthesia of the inferior alveolar nerve (IAN) ââwhen extracting lower third molars. The aim of this study is to determine the distribution of complications in deeply impacted third molar surgery, to identify specific risk factors influencing the most common perioperative (OAC, IAN hypesthesia) and to compare these results with other studies. MATERIALS AND METHODS: The clinical findings, digital panoramic radiographs, intra- and postoperative data of 80 patients with a total of 232 impacted third molars that had been subjected for tooth extraction, from December 2022 and August 2023, were collected and analyzed. Perioperative complications (IAN hypesthesia, OAC, hypesthesia lingual nerve, postoperative bleeding, postoperative infection) were identified. A risk analysis for OAC and IAN hypesthesia was performed regarding perioperative data. RESULTS: Overall, the rate of OAC for the right upper third molar was 12.8% and for the left upper third molar 15.6%. The complication rates regarding transient hypesthesia were 8.1% for the left IAN and 7.3% for the right IAN. The distance to maxillary sinus, the depth score according to Pell and Gregory, the bone coverage score, the operation time, the tooth's angulation and the type of surgeon (oral surgeon, DMD) were identified as significant risk factors for the occurrence of OAC. The minimum distance to IAN, the bone coverage score, the total operation time and the operation by an oral surgeon (DMD) were identified as significant risk factors for hypesthesia of the IAN. CONCLUSION: Next to the risk factors from above, the present study is one of the first showing that patients who were primarily operated on by an oral surgeon (DMD) and not a maxillofacial surgeon (MD, DMD) showed higher rates of OAC and IAN hypesthesia in impacted third molar extraction. The results of this study can serve as a baseline for further studies to investigate complication patterns in impacted third molar surgery.

BACKGROUND/AIM: The styloid process (SP) becomes clinically relevant when it shows enlargement (>30 mm) in the sense of an elongated SP (ESP) and/or increasing calcification leading to Eagle Syndrome (ES). Panoramic radiograph (PR) or computed tomography (CT) are part of the routine diagnostics in ES. Currently, CT is considered the gold standard. The aim of this study was to investigate the accuracy in the diagnostics/measurements of SP/ESP throughout a comparative study between PR and CT. Furthermore, in addition to measuring established parameters, this study aimed to determine the currently unexamined width in the base and tip of the SP. PATIENTS AND METHODS: The present study examined the radiological findings of bilateral SP in 100 patients who received both PR and CT on the same day. Measurements of the length of the SP and width at the basis and tip were performed. Furthermore, calcification patterns, Langlais classification and the prevalence of ESP were analyzed. RESULTS: There was a highly significant correlation between PR and CT measuring SP for every parameter. Males showed significantly longer SP than females among the age group between 18-75 years. The results of the length measurements of the SP (male: right SP=32.98 mm; left SP=35.21 mm; female: right SP=30.31 mm; left SP=30.92 mm) significantly exceeded the values of comparable studies. CONCLUSION: Consequently, it can be concluded that PR provides accurate measurements when compared to CT for measuring and diagnosing SP/ESP/Eagle syndrome. This study was one of the first to examine the width of the SP in the base and tip, thus these measurements can serve as a baseline for further studies. Since the mean lengths of SP exceeded 30.0 mm in the present study, these findings raise the question of whether the cut-off of 30.0 mm is adequate for the diagnosis of ESP.

BACKGROUND: In 2020, the coronavirus SARS-CoV-2 led to a pandemic that had a major impact on the global health care systems. The aim of this study was to analyze the impact of the Covid-19 pandemic on nasal bone (NB) fracture patterns/distributions and circumstances in a German cranio-maxillofacial trauma center. MATERIALS AND METHODS: This retrospective study compared the nasal fracture patterns of patients in the PreCovid (PC) era (February 2019 - January 2020) with patients in the IntraCovid (IC) era (February 2020 - January 2021). In addition to baseline characteristics, the type of NB fractures, the circumstances leading to NB fracture and hospital admissions/treatments were analyzed. RESULTS: The present study showed a significant decrease in the total number of NB fractures during the Covid-19 pandemic. In the IC period, a significant increase in falls and virus-/flu associated syncopes leading to NB fractures was detected. At the same time, a significant decrease in sports accidents, road traffic accidents and interpersonal violence leading to NB fractures was observed in the IC period. Under the influence of the Covid-19 pandemic, a significant increase in accidents at home, accidents during the weekdays and closed reductions under local anesthesia was detected when being compared to the PC period. The daytime of trauma leading to NB fractures also changed significantly from night-time (PC) to morning-time (IC). CONCLUSION: The Covid-19 pandemic had a significant impact on the NB fracture circumstances and treatment modalities. Therefore, the results of this study can serve as a baseline for further studies of the impact of the Covid-19 pandemic on NB fracture patterns among different countries.
