– The aim of this study was to investigate pre‐injury factors, causes of dental injuries and healing complications after traumatic injuries to permanent teeth. The analysed sample comprised 889 ...permanent teeth of 384 patients, who were treated in the Dentistry Department in Faculty Hospital in Pilsen. Enamel‐dentin fractures 233 teeth (26.2%) and lateral luxations 207 teeth (23.3%) were the most frequent injuries. The age of the patients at the time of injury varied between 7 and 65 years. Predominantly, children were affected 587 injured teeth (66.0%). The most frequent causes of injuries in patients older than 11 years were various sport activities, predominantly bicycling. Pulp necrosis was observed in 239 teeth (26.9%). It was the most frequent post‐traumatic complication in all types of dental traumas. Teeth with a completed root formation demonstrated a higher prevalence of pulp necrosis than teeth with an incomplete root formation in all types of luxation injuries. External root resorption was observed in 144 teeth. The rate of inflammatory resorption differed between the various types of luxation injuries (extrusive luxation 5.6%, lateral luxation 11.6%, intrusive luxation 33.3%). Following avulsion and replantation, active inflammatory resorptions were diagnosed in 13 (26.5%) of 49 replanted teeth and ankylosis/replacement resorptions were observed in 21 (42.9%) of 49 replanted teeth. After avulsion, primarily, immature teeth were affected by these complications. Within the observation period of 5 years, 39 teeth (4.4%) had to be removed (16 teeth with root fractures, 19 avulsed and replanted teeth, 3 luxated teeth, 1 tooth with crown‐root fracture).
Health problems of premature infants can affect both general and oral health. The enamel defects, poor dietary and oral hygiene habits may predispose these children to dental caries. This study was ...conducted to assess the impact of very low birth weight and prematurity on caries risk in early childhood.
The study cohort consists of 189 of one year old infants. Anamnestic data were obtained from hospital records, feeding practice, bed-time sugar drinks and oral hygiene onset from questionnaires. Saliva samples of children and their mothers were collected for the detection of cariogenic pathogens.
VLBW newborns had significantly shorter gestation age (29.6 vs. 38.8)) and lower mean birthweight (1124 g vs 3315 g) compared to NBW ones (p < 0.0001). Statistical significance has been found in the presence of early morbidity (p < 0.0001) and regular medication intake (p = 0.007). VLBW children got more frequently sweetened drinks during the day and night (p = 0.007). Regular oral hygiene practice was more frequent in full term group (p = 0.002). There was statistical difference in the presence of enamel hypoplasia in VLBW children (p = 0.033) but no statistical difference in the presence of hypomineralization (p = 0.0736) in comparison to NBW individuals. Proportional representation and count of S. mutans did not reveal statistical difference neither in both groups of children (p = 0.484) nor in both groups of mothers (p = 0.385).
The study confirmed anamnestic and medical differences between both groups. The proportional representation and count of S. mutans did not reveal statistical difference neither in VLBW and NBW children, nor in their mothers.
The aim of the present study was to evaluate the general and oral health status of a group of preterm one-year-old very low (VLBW) and extremely low birthweight (ELBW) infants and make a comparison ...with full-term one-year-old normal birthweight infants (NBW).
A cross-sectional study was conducted in 102 one-year-old preterm VLBW and ELBW infants, and the data obtained were compared to 87 one-year-old full-term NBW infants. The infants' medical histories were obtained from hospital records and interviews with the mothers. The oral cavities of all infants were examined under the same conditions. The chi-square test, Pearson's chi-square test of independence and Mann-Whitney test were used for the statistical evaluation, with P < 0.05 considered statistically significant. Relative risk (RR) and 95% confidence interval (CI) estimates for variables significantly associated with oral findings were calculated.
Both perinatal variables (gestational age, mode of delivery, birthweight, Apgar score, resuscitation, orotracheal intubation and presence of intraoral pathology) and neonatal variables (antibiotic treatment and infections) had a significant association with prematurity, VLBW and ELBW. The one-year-old preterm VLBW and ELBW infants frequently suffered from general diseases, frequently received regular medication and had fewer erupted primary teeth; they also had a higher prevalence of developmental defects of the enamel and deformations of the hard palate.
This study confirmed anamnestic, medical and oral differences between one-year-old preterm VLBW and ELBW and full-term NBW infants.
An ocular adnexal apocrine adenocarcinoma (OAAA) is an extremely rare, but potentially aggressive and life-threatening tumor with ill-defined management based only on recommendations from a limited ...number of reported cases. The development of cervical lymphocele following neck dissection is a very rare complication, but one with well established methods for prevention and treatment. Here we describe a previously unreported case of salvage surgery including neck dissection for OAAA in addition to an emergence of cervical lymphocele. A literature review of current knowledge on both pathological conditions is included.
A 58-year-old man suffering from OAAA, previously treated with multiple eye-sparing excisions and adjuvant proton therapy, underwent salvage surgery for locoregional recurrence of the tumor. A partial orbitectomy with orbital exenteration, primary reconstruction and left-sided neck dissection was performed. The procedure was complicated by a cervical lymphocele resolved after the surgical therapy. The patient remained disease-free during the one-year follow-up.
OAAA is a locally aggressive tumor with potential to local or distant metastatic spread. Whole-body staging, regular clinico-radiological follow-up and stage-dependent therapy with surgery as the first-choice treatment is required. A cervical lymphocele as a complication of especially left-sided neck dissection is managed with a conservative or surgical therapy according to the level of lymph leakage, extent and localization of lesions, presence of local or systemic disorders and the period from primary surgery.
Abstract
Objective
Preterm birth is connected to a delay in the development and eruption of primary teeth. The aim of the study is to present clinical findings, complications and management of ...prematurely erupted primary teeth.
Subjects
Three premature neonates with prematurely erupted teeth were examined during a 3-year period. The gender, gestational age, birthweight, mode of delivery and general health status were recorded. The literature search was conducted using several databases.
Results
The intraoral examination of three premature neonates revealed the presence of partially erupted lower central incisors. All teeth erupted between 4 and 6 weeks after preterm birth and were extracted due to their hypermobility. Two retrospective studies and 10 case reports concerning preterm infants with natal or neonatal teeth were found.
Conclusion
Careful examination of preterm infants with natal or neonatal teeth is very important not only for a treatment decision but also for the possible presence of syndromic conditions.
The colonization of the oral cavity by cariogenic and periodontal pathogens occurs earlier than previously thought. This study aimed to identify the presence and quantity of representative cariogenic ...and periodontal pathogens in the oral cavities of 6- and 12-month olds and to evaluate the influence of C-section delivery on early
Streptococcus mutans
(Sm) colonization of the oral cavity. The research cohort was composed of 59 infants (35 infants were delivered vaginally and 24 via C-section) and their mothers. At 6 months of age, the infants were examined, and unstimulated saliva samples were collected. Variables concerning mothers were DMF index and salivary levels of Sm. Repeated saliva samples were taken 6 months later. The representative cariogenic and periodontal microorganisms were identified, and their quantities were measured using a polymerase chain reaction-based method. The relationships between the presence of detected microbes, the mode of delivery, and maternal variables were evaluated using paired
t
tests, chi-squared test, and ANOVAs. High rates of cariogenic bacteria,
Aggregatibacter actinomycetemcomitans
(Aa) and
Fusobacterium nucleatum
(Fn), were found in both infant cohorts. An analysis of the differences between delivery methods revealed that the group of 6-month-old vaginally delivered infants had a significantly higher amount of Sm. We conclude that the cariogenic bacteria, Aa and Fn, are present in edentulous infants. This presence increases in the months following the eruption of the deciduous teeth. Results did not confirm the influence of C-section delivery on the early Sm colonization of the oral cavity.
The aim of this study is to evaluate the results of dentigerous cysts enucleation with preservation of cyst-associated teeth as a single procedure in a group of children and preadolescents. A ...retrospective case series of seven patients with 15 unerupted developing teeth associated with or adjacent to dentigerous cysts was conducted. Patients were treated using the uniform surgical protocol (cystectomy, preservation of cyst-associated teeth, without use of orthodontic traction, primary wound closure). The metric analysis of the cysts and unerupted teeth on CBCT and an evaluation of the state of involved teeth after the treatment was performed. The mean age of patients was 9.0 ± 2.1 years (range 5–12 years, median = 9 years). All teeth erupted spontaneously. No serious postoperative complications or recurrences of lesions were detected. The mean follow-up was 53.1 ± 15.7 months (range 25–71 months, median = 52 months). The cystectomy of dentigerous cysts with preservation of associated teeth may be considered an alternative to marsupialization in children and preadolescents.
Abstract Background Langerhans cell histiocytosis is a rare disease characterized by monoclonal proliferation and migration of special dendritic cells. This disease primarily affects bones, but ...occurs less frequently in other organ systems or may manifest as a multisystem disease. Case reports Extraoral and intraoral symptoms of Langerhans cell histiocytosis are described in a 13-month-old female and a 5-month-old male infant. Dermatitis was found on the scalp, abdomen, flexures and in intertrigineous areas in both patients. The intraoral examination of the 13-month-old infant showed premature eruption of all maxillary deciduous molars, loosening and significant damage of periodontal tissues (gingivitis with bleeding, swelling of palatal mucosa, periodontal pockets) resembling severe periodontitis. In the oral cavity of the 5-month-old predentate infant bilateral swellings of maxillary alveolar mucosa with deep ulcerations were seen. The oral and skin symptoms in both infants were indications for biopsy. Langerhans cell histiocytosis was confirmed histologically and immunohistochemically. Conclusion Oral findings in Langerhans cell histiocytosis may be the only clinical symptom of the disease; therefore the role of dentists in establishing diagnosis is very important.
