This pilot study aimed to implement and assess the performance of an experimental artificial intelligence (AI) mobile phone app in the real-time detection of caries lesions on bitewing radiographs (BWRs) with the use of a back-facing mobile phone video camera. The author trained an EfficientDet-Lite1 artificial neural network using 190 radiographic images from the Internet. The trained model was deployed on a Google Pixel 6 mobile phone and used to detect caries on ten additional Internet BWRs. The sensitivity/precision/F1 scores ranged from 0.675/0.692/0.684 to 0.575/0.719/0.639 for the aggregate handheld detection of caries in static BWRs versus the stationary scanning of caries in a moving video of BWRs, respectively. Averaging the aggregate results, the AI app detected—in real time—62.5% of caries lesions on ten BWRs with a precision of 70.6% using the back-facing mobile phone video camera. When combined with the AI app’s relative ease of use and speed and the potential for global accessibility, this proof-of-concept study could quite literally place AI’s vast potential for improving patient care in dentists’ hands.

Oral cancer (OC) is the 16th most common cancer worldwide. In Sri Lanka, OC is the most prevalent cancer among men and the eighth among women. In most instances, OC is preceded by clinically recognizable disorders appearing on the oral mucosa, termed oral potentially malignant disorders (OPMD). The distribution of OC among low- and middle-income socioeconomic groups contributes to various factors. Poor oral health literacy, a lower quality of higher education, and the economic burden results in neglected oral health. The further economic recession has led to the formation of risk habits, such as chewing betel quid, smoking and the consumption of alcohol, among these groups to minimize stress levels. But with a lack of oral health awareness, the incidences of OC increase in this category. This review elaborates on a few cross-sectional studies conducted in various locations in Sri Lanka, discussing the low awareness of neglected oral health, the usage of tobacco in a smokeless and non-smokeless manner, consuming alcohol, and the chewing of betel nuts. This review aims to overcome the barriers in these low- and middle-income socioeconomic groups in developing nations such as Sri Lanka by creating more awareness and minimizing the incidence and diagnosis and treatment at early stages to improve the quality of life as well as longevity.

Adverse drug reactions (ADRs) represent a significant threat to patients’ safety in dentistry, necessitating proactive measures for prevention and treatment. However, identifying ADRs of dental and oral interest can be challenging, and underreporting remains a persistent issue globally. This paper illustrates a smart system to help Italian healthcare personnel, including dentists, in identifying and reporting dental and oral ADRs. This educational program is within a larger multi-regional project financed by the Italian Agency of Drugs (AIFA). The proposed system comprises a free online questionnaire on ADRs of dental interest (including specific items about awareness and attitudes), and after the free consultation of an atlas of clinical images of dental and oral ADRs linked with a digital synopsis of drugs potentially related to ADRs. This section of the project was presented in April 2023 at the 30th National Congress of the Italian College of University Professors of Dental Disciplines, and the system appears to hold tremendous potential to improve the knowledge of healthcare professionals on oral and dental ADRs.

The aim of this study was to analyse if bracket systems could affect the incisors’ decompensation in a group of patients affected by dentoskeletal Class III malocclusion and on the duration of presurgical orthodontics. A single-centre retrospective study was carried out on two groups of patients affected by dentoskeletal Class III and who underwent orthognathic surgery. Group 1, comprising 25 subjects (13 males, 12 females; mean age, 27.4 y.o.), was treated with interactive self-ligating brackets; group 2, comprising 10 subjects (5 males, 5 females; mean age, 27.2 y.o.), was treated with conventional twin brackets. Bracket prescription and archwire sequence were the same for both groups. Data were collected about age, upper incisors’ axis (UI^ANS-PNS), lower incisors’ axis (IMPA), and the total duration of presurgical orthodontics and were then compared between the two groups. The variation in the upper incisor axis and the duration of presurgical orthodontics was not significant between the groups, while the difference in the IMPA was small but significant. The use of a self-ligating bracket did not influence the decompensation of the upper incisors or the duration of presurgical orthodontics when compared with conventional ligating brackets. The difference in the IMPA was significantly different but clinically negligible.

The increased number of adults seeking orthodontic treatment has led to the need for faster results as social limitations arise with the use of fixed or even removable appliances. Corticotomy-assisted orthodontic treatment (CAOT) has been proposed as a technique that accelerates tooth movement and leads to a substantial reduction in treatment time. This review was conducted by searching four databases for original articles about CAOT, review articles and articles about alternative techniques and periodontal effects up to 31 December 2022. The aim of the review was to present the historical and biological background of CAOT, the description of the technique and some alternative and less invasive techniques that have been proposed. Indications, contraindications and periodontal side effects are also discussed.

Aim: Our previous three-year randomized control trial showed that the application of MI Varnish™ (5% NaF/CPP-ACP) every 3 months reduced further caries development in 6- and 12-year-olds over a 3-year period. The purpose of this secondary analysis was to investigate whether MI Varnish™ had a differential effect on cumulative caries increment on different tooth surfaces. Methods: Group 1 (n = 48) (6-year-old children) and Group 3 (n = 47) (12-year-old children) received quarterly varnish applications, while Group 2 (n = 48) (6-year-old children) and Group 4 (n = 37) (12-year-old children) did not receive varnish applications. ICDAS caries scoring classified lesions as non-cavitated (n/c) lesions (ICDAS 1 and 2), cavitated (c) lesions (ICDAS II 3–6), non-cavitated lesions around restorations (CARn/c), and cavitated lesions around restorations (CARc). Thus, ‘decayed’ in DFS was calculated as (ICDAS 1–6 + CARn/c + CARc). The Chi-square test, Welch test (paired-t test), risk ratio test, and Pearson correlation coefficient were used for statistical analysis (α = 0.05). Results: After comparing baseline and 36-month data, in group 1, there was a significant (p < 0.01) reduction in caries in occlusal (23.11%) and proximal (21.35%) surfaces and a non-significant reduction in buccal/lingual surfaces (5.28%). In group 2, caries reduction was significant (p < 0.01) in occlusal surfaces (38.52%) but non-significant in proximal (7.78%) and buccal/lingual (7.12%) surfaces. In groups 3 and 4, significant (p < 0.001) increases in caries were observed in proximal (36.03% (group 3)/54.30% (group 4)) and buccal/lingual surfaces (51.02% (group 3)/45.98% (group 4)), and a non-significant increase was observed in occlusal surfaces (11.49% (group 3)/22.01% (group 4)). The relative risk had increased by 4% only on proximal surfaces in 6-year-olds. Conclusions: the application of MI Varnish™ every 3 months demonstrated a caries reduction effect on interproximal and occlusal surfaces among 6- and 12-year-old children. (Trial registration ISRCTN10584414).

Triethylene glycol dimethacrylate (TEGDMA) and 2-hydroxyethyl methacrylate (HEMA), two resin monomers often used in dental restorative materials, are leached due to insufficient polymerization and contact cells of the oral cavity. Despite reports on the cytotoxicity of these monomers on different oral cells, their effects on oral melanocytes remain unknown. This first report provides novel data on the impact of TEGDMA and HEMA monomers on melanocyte viability and functions by utilizing primary human melanocytes from lightly pigmented (HEMn-LP) foreskin as a representative model of oral melanocytes. Results show that TEGDMA induced higher cytotoxicity than HEMA and significant morphological alterations (increased dendricity) in melanocytes at the lowest concentration of 0.25 mM onwards. HEMA achieved similar effects but only at an 8-fold higher concentration (2 mM), while lower concentrations did not induce any change in cellular melanin or morphology. HEMA suppressed intracellular tyrosinase activity at 1 and 2 mM, while TEGDMA had no effect, although none of the monomers altered tyrosinase activity directly in an acellular system. TEGDMA and HEMA did not alter cellular ROS production. TEGDMA suppressed LPS-induced IL-6 cytokine secretion in cells to a greater degree than HEMA, indicating its greater capacity to dampen the immune response. Our findings demonstrate that TEGDMA and HEMA at different concentrations induce cytotoxicity to melanocytes, stimulate their dendricity and impair immune responses, indicative of altered melanocyte homeostasis. Furthermore, it is worth considering alternative monomers in light of the cytotoxicity exhibited by TEGDMA at lower millimolar concentrations compared to HEMA as well as its significant impact on melanocyte differentiation and immune function.

The study aimed to evaluate knowledge, awareness, and perception of tooth-supported and implant-supported prostheses among an adult sample in Sana’a city in Yemen. A cross-sectional descriptive–analytical study was conducted on a convenient sample of 509 participants. All participants were aged 18 years and above with at least 1 missing tooth. The participants visited the public or private hospitals or their outpatient clinics in the municipality of the capital, Sana’a, Yemen. Their chief complaints when visiting the hospitals were not related to dental problems but to general healthcare. The participants who agreed and signed the consent form were interviewed and examined. The data were then recorded and statistically analyzed. The levels of awareness and knowledge of implant-supported prostheses among the 509 participants were low (58.0%, 33.6%, respectively). A significant positive correlation was found between genders (p = 0.003 for males, p = 0.000 for females), but no significant differences were detected between genders related to the awareness and knowledge of tooth-supported prostheses (p = 0.690). Most of the respondents had a low level of awareness, knowledge, and perception of treatment options for tooth replacement modalities.

Background: Surveys in Tanzania show that pregnant women have a significant burden of oral disease, although there is still little literature on the variation of their intraoral electrolytes. The present study investigated changes in salivary calcium (Ca2+), phosphate (PO43−), and hydrogen (H) ions during pregnancy and the correlation between salivary pH and hemoglobin levels. Methodology: A cross-sectional study involved sixty (60) pregnant women stratified by trimester and twenty (20) non-pregnant women attending an antenatal clinic at Mnazi Mmoja Hospital. Consecutive sampling was used, saliva was collected, and electrolyte levels were measured. Gestation age was the independent variable, whereas saliva pH and calcium and phosphate ion concentrations and hemoglobin levels were the dependent variables. Results: A difference in calcium concentration (z = −3.145, p = 0.001) and salivary pH (t = −2.49, p = 0.014) was observed between pregnant and non-pregnant women. Kruskal–Wallis tests for saliva Ca2+ and PO43− and ANOVA for saliva pH revealed differences in concentrations of saliva Ca2+, PO43−, and pH levels between trimester groups (saliva Ca2+ (H = 9.91, df = 3, p = 0.019), saliva PO43− (H = 12.36, df = 3, p = 0.006), saliva pH (F (3.76) = (16.42); p < 0.001)). Pearson’s correlation tests showed no association between salivary pH and hemoglobin levels. Conclusions: Pregnancy is associated with a reduction in saliva pH and saliva calcium levels with a progressive increase in the magnitude of reduction from the first trimester to the third trimester. Saliva phosphate reduction was noticed during the third trimester only and saliva pH levels were independent of hemoglobin levels.
背景:坦桑尼亚的调查显示，孕妇有严重的口腔疾病负担，尽管关于其口内电解质变化的文献仍然很少。本研究探讨了妊娠期间唾液钙(Ca2+)、磷酸(PO43−)和氢(H)离子的变化以及唾液pH值与血红蛋白水平的相关性。方法:一项横断面研究涉及60(60)名按孕期分层的孕妇和20(20)名在Mnazi Mmoja医院产前诊所就诊的非孕妇。连续取样，收集唾液，测量电解质水平。孕龄为自变量，唾液pH、钙、磷酸盐离子浓度和血红蛋白水平为因变量。结果:孕妇和非孕妇的钙浓度(z = - 3.145, p = 0.001)和唾液pH (t = - 2.49, p = 0.014)存在差异。唾液Ca2+和PO43−的Kruskal-Wallis试验和唾液pH的方差分析显示，三个孕期组之间的唾液Ca2+、PO43−和pH水平存在差异(唾液Ca2+ (H = 9.91, df = 3, p = 0.019)、唾液PO43−(H = 12.36, df = 3, p = 0.006)、唾液pH (F (3.76) = (16.42);P < 0.001))。Pearson相关试验显示唾液pH值与血红蛋白水平无关联。结论:妊娠与唾液pH值和唾液钙水平的降低有关，并且从妊娠早期到妊娠晚期，降低幅度逐渐增加。唾液磷酸盐减少仅在妊娠晚期才被注意到，唾液pH值与血红蛋白水平无关。

The present study investigated changes in salivary calcium (Ca2+), phosphate (PO43−), and hydrogen (H) ions during pregnancy and the correlation between salivary pH and hemoglobin levels. Methodology: A cross-sectional study involved sixty (60) pregnant women stratified by trimester and twenty (20) non-pregnant women attending an antenatal clinic at Mnazi Mmoja Hospital. Consecutive sampling was used, saliva was collected, and electrolyte levels were measured. Gestation age was the independent variable, whereas saliva pH and calcium and phosphate ion concentrations and hemoglobin levels were the dependent variables. Results: A difference in calcium concentration (z = −3.145, p = 0.001) and salivary pH (t = −2.49, p = 0.014) was observed between pregnant and non-pregnant women. Kruskal–Wallis tests for saliva Ca2+ and PO43− and ANOVA for saliva pH revealed differences in concentrations of saliva Ca2+, PO43−, and pH levels between trimester groups (saliva Ca2+ (H = 9.91, df = 3, p = 0.019), saliva PO43− (H = 12.36, df = 3, p = 0.006), saliva pH (F (3.76) = (16.42); p < 0.001)). Pearson’s correlation tests showed no association between salivary pH and hemoglobin levels. Conclusions: Pregnancy is associated with a reduction in saliva pH and saliva calcium levels with a progressive increase in the magnitude of reduction from the first trimester to the third trimester. Saliva phosphate reduction was noticed during the third trimester only and saliva pH levels were independent of hemoglobin levels.","PeriodicalId":19616,"journal":{"name":"Oral surgery, oral medicine, oral pathology, oral radiology, and endodontics","volume":"36 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76673886","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
The purpose of this study was to report a rare case of an odontogenic keratocyst occurring in the edentulous jaw area. A 64-year-old man presented with a painful swelling of the right posterior mandibular vestibule that prevented him from wearing a complete lower denture. Upon intraoral clinical examination, the patient was totally edentulous and had two removable complete dentures. He had a fistula in the vestibular mucosa of edentulous site 48 that was painful upon palpation. Radiological examination revealed an unilocular radiolucent lesion with a continuous peripheral sclerotic border, centered on both the mandibular angle and right branch. Differential diagnosis mainly included a residual cyst and an odontogenic cystic tumor. The biopsy and the excisional material allowed a diagnosis of an odontogenic keratocyst to be made, the cyst being lined by a uniform parakeratinized squamous epithelium, corrugated in places, showing intercellular edema in places, with a well differentiated basal cell layer ranging from cuboidal to columnar in shape, a relatively thin, inflammation-free fibrous wall, and a cyst lumen that contained varying amounts of desquamated keratin. In this case, the surgical risk was represented by paresthesia of both the inferior alveolar and the lingual nerves. The lesion was enucleated without any complications, and the follow-up after 1 year did not reveal any nerve functional damage. Our case underlines the importance for the clinicians to consider a keratocyst in the differential diagnosis of cyst-like lesions presenting in an edentulous area.
