Congenital Insensitivity to Pain with Anhidrosis: A Case Report.

Hereditary sensory and autonomic neuropathy type 4 (HSAN4), or congenital insensitivity to pain with anhidrosis (CIPA), is a rare autosomal recessive disorder caused by mutations in the NTRK1 gene, resulting in pain insensitivity, anhidrosis, and temperature dysregulation. This report focuses on oral manifestations in an 11-year-old girl with CIPA, highlighting the need for early intervention and comprehensive care. The patient had a history of recurrent oral injuries and an unexplained fever, with a confirmed HSAN4 diagnosis through genetic analysis. Clinical features included pain insensitivity, anhidrosis, and intellectual disability. Dental history revealed emergency care, suboptimal oral hygiene, early tooth loss, and infections. Extra-oral examination showed nail-biting and injuries, while intra-oral assessment revealed ulcers and scars. Radiographic evaluation indicated mandibular alveolar bone thinning and periapical lesions in the lower incisors. This case emphasizes the complex challenges of CIPA, including pain insensitivity, recurring fever episodes, and self-inflicted injuries. Early diagnosis and specific dental care are vital to prevent orofacial trauma, necessitating a proactive interdisciplinary approach for comprehensive care.

Oral Facial Manifestations of Sanjad-Sakati Syndrome: A Literature Review.

AIM: To perform a comprehensive review of orofacial manifestations of Sanjad-Sakati syndrome (SSS). METHODS: A comprehensive electronic literature search was performed using PubMed, Scopus and Cochrane library databases. The search keywords included were "Sanjad-Sakati syndrome (SSS)", "dental manifestations", "dental management", "oral health", "dental care for patients with SSS", "dental health of people with SSS", "caries", and "oral hygiene". The inclusion criteria were papers published only in English, papers published by August 2021, and papers discussing orofacial manifestations of SSS and language. RESULTS: The search of the databases retrieved eleven case reports and three case series studies. Overall, 56 cases (11 case reports and 3 case series studies) were reported on Sanjad-Sakati syndrome in the published literature. The majority of the reports are from the Middle Eastern region. CONCLUSIONS: The reported orofacial manifestations of SSS include beaked nose, depressed nasal bridge, enamel hypoplasia, hypodontia, low-set ears, posteriorly rotated ears, deep-set eyes, microcephaly, microdontia, micrognathia, prominent forehead, retrognathia, and thin lips. The review paper also establishes the importance of the dental under general anesthesia in SSS individuals.

Oral Manifestations and Maxillo-Facial Features in the Acromegalic Patient: A Literature Review.

Background: Acromegaly is a chronic disease caused by an abnormal secretion of growth hormone (GH) by a pituitary adenoma, resulting in an increased circulating concentration of insulin-like growth factor 1 (IGF-1). The main characteristics are a slow progression of signs and symptoms, with multisystemic involvement, leading to acral overgrowth, progressive somatic changes, and a complex range of comorbidities. Most of these comorbidities can be controlled with treatment. The literature reveals that the most evident and early signs are those related to soft tissue thickening and skeletal growth, especially in the head and neck region. Methods: The authors reviewed the available literature on the clinical oro-dental features of acromegaly, selecting articles from PubMed and Google Scholar. The aim of this review was to summarize all the reported clinical oro-dental features of acromegalic patients. Results: The most common facial dimorphisms involved the maxillo-facial district, with hypertrophy of the paranasal sinuses, thickening of the frontal bones, and protruding glabella, which may be associated with joint pain and clicks. Regarding the oro-dental signs, the most frequent are dental diastema (40-43%), mandibular overgrowth (22-24%), mandibular prognathism (20-22%), and macroglossia (54-58%). These signs of acromegaly can be significantly reduced with adequate treatment, which is more effective when initiated early. Conclusions: Increased awareness of acromegaly among dentists and maxillo-facial surgeons, along with the early identification of oro-facial changes, could lead to an earlier diagnosis and treatment, thereby improving patients' quality of life and prognosis.

The role of the dentist and orthodontist in recognizing oro-facial manifestations of acromegaly: a questionnaire-based study.

PURPOSE: Oro-facial manifestations of acromegaly are among the earliest signs of the disease and are reported by a significant number of patients at diagnosis. Despite this high prevalence of acromegaly oral manifestation, dentists do not play a pivotal role in acromegaly identification and diagnosis. The aim of our study was to evaluate the ability of dentists and orthodontists in the early recognition of the oro-facial manifestations of acromegaly. METHODS: A telematic questionnaire was administered to dentists and orthodontists. The questionnaire included photos with facial and oral-dental details and lateral teleradiography of acromegaly patients (ACRO). RESULTS: The study included 426 participants: 220 dentists and 206 orthodontists. Upon reviewing the photos, dentists most often observed mandibular prognathism and lips projection, while orthodontists also reported the impairment of relative soft tissue. Orthodontists, who usually use photos to document patients' oral-facial characteristics, paid more attention to oral-facial impairment than dentists. During dental assessment, 90% of the participants usually evaluated tongue size and appearance, diastemas presence, and signs of sleep impairment (mainly orthodontists). Orthodontists were also more able to identify sella turcica enlargement at teleradiography. A total of 10.8% of the participants had ACRO as patients and 11.3% referred at least one patient for acromegaly suspicion. CONCLUSION: The study highlighted dentists' strategic role in identifying ACRO. Increasing dentists' awareness about acromegaly clinical issues may improve early diagnosis, potentially resulting in an increased quality of life and decreased mortality among ACRO.

Oral manifestations in children with mucopolysaccharidosis / Manifestações orais de mucopolissacaridose em crianças

BACKGROUND: Patients with mucopolysaccharidosis have several changes of the stomatognathic complex, representing a challenge for dentists. OBJECTIVE: The study aimed to evaluate and characterize oral health in patients with mucopolysaccharidosis in a reference center of Portugal. METHOD: The sample consisted of twelve participants with mucopolysaccharidosis followed in Metabolic Diseases Unit of the S. João Hospital Centre and twelve healthy participants followed at Faculty of Dental Medicine, University of Porto. The clinical oral evaluation was performed by a complete extra-oral and intra-oral examination to assess the presence of oral pathologies, gingival index and occlusion status. RESULTS: Mucoplysaccaridosis patients and controls presented similar age ranges and sex distribution. In comparison to controls, children with mucopolysaccharidosis presented a higher prevalence of tooth decay, gingival bleeding, macroglossia, dental hypoplasia, lingual interposition, delayed tooth eruption, anterior open bite, right and left posterior cross-bite, limitation of mouth opening, alteration on the size and shape of the teeth, diastemata and maxillary compression. CONCLUSIONS: Patients with mucopolysaccharidosis have a high prevalence eruption delay, teeth morphology alterations, occlusal problems, dental caries and bleeding gums, highlighting the need of oral health care providers to improve diagnostics and preventive protocols to overcome the factors that limit the oral health of these patients and promote together with parent/caregiver efficient oral care strategies.

CONCLUSÃO: Pacientes com mucopolissacaridose apresentam maior prevalência de erupção dentária atrasada, alterações morfológicas dentárias, problemas oclusais, cáries dentárias e gengivas inflamadas, reforçando a necessidade de prestadores de saúde oral para melhorar diagnósticos e protocolos preventivos para ultrapassar os fatores que limitam a saúde oral destes pacientes e promover em conjunto com pais/cuidadores estratégias de saúde oral eficientes.

Sturge-Weber syndrome: Continued vigilance is needed.

Sturge-Weber syndrome (SWS) is a non-hereditary congenital disorder due to somatic mosaic mutations in the GNAQ gene. The classical presentation relates to the brain lesion (cerebral angiomatous lesion of leptomeninges, which is responsible for epileptic seizures, hemiparesis and mental retardation), skin lesion (unilateral facial nevus), ocular and oral involvement. We present a 12-year-old boy who was referred to the Division of Pediatric Neurology, King Saud University Medical City, Riyadh, Saudi Arabia with left-sided hemiparesis. Physical examination showed a port wine stain involving the right side of the face, extending to the upper thorax, and enlargement of both the right eye globe and cornea (megalocornea), indicating the presence of glaucoma. Following urgent referral to ophthalmology service, his eye condition improved dramatically post surgery. Neuroradiological investigations, including cranial computed tomography (CT) and magnetic resonance angiography (MRI) revealed the classical brain lesions of SWS, as well as right leptomeningeal choroidal angioma. Ten months later, he developed focal-onset seizures which responded to treatment. His cognition is normal with good school performance. Continued vigilance is needed to identify and manage the complications of SWS.

Atendimento odontológico ao paciente diabético tipo 1: [revisão] / Dental care for type 1 diabetic patients: [review]

Diabetes mellitus (DM) é uma desordem metabólica caracterizada por uma alteração nos níveis de insulina. Há dois tipos principais de DM: tipo 1, onde há deficiência total de secreção de insulina, e tipo 2, onde há uma inadequada secreção compensatória. Dentre as alterações bucais destes pacientes estão: baixo fluxo salivar e aumento de seu pH e viscosidade, que são fatores de risco para cárie. A presente revisão da literatura tem por objetivo fornecer maiores informações sobre esta síndrome, assim, como orientar o clínico como proceder com estes pacientes.

Diabetes mellitus (DM) is a metabolic disorder characterized by deficient management of insulin. Two main types of DM exist: type 1, a total deficiency in insulin secretion, and type 2, a combination of resistance to insulin action and inadequate compensatory insulin secretion. Amongst the buccal alterations of these patients, there are reduction of the flow and increase of the saliva's acidity and viscosity, risk factors for caries. This review intends to provide not only general information about this syndrome, but also orientations how to preceed with these patients.

Dental manifestations in bariatric patients: review of literature

The rate of bariatric surgery has significantly risen in the past decade as an increasing prevalence of extreme obesity can be observed. Although bariatric surgery is an effective therapeutic modality for extreme obesity, it is associated with risk factors affecting also oral health. Based on an overview of the current literature, this paper presents a summary of dental manifestations in bariatric patients. Bariatric surgeries are associated with an increased risk for gastro-esophageal reflux which in turn might account for the higher amount of carious and erosive lesions observed in bariatric patients. As a result, also dentin hypersensitivity might be observed more frequently. The current data indicate that recommended postsurgical meal patterns and gastric reflux might increase the risk for dental lesions, particularly in the presence of other risk factors, such as consumption of sweet-tasting foods and acidic beverages. Further research is needed to evaluate the correlation of bariatric surgery and the development of dental diseases.
