General Thermography

James Stewart Campbell, M. Nathaniel Mead
Though much has been reported about the effectiveness of facial thermography in detecting dental disease, good-quality studies showing definite qualitative or quantitative data are lacking.84 As the bodies of the teeth are not directly adjacent to the external skin surface, being separated from the skin by the buccal cavity and cheek, localized tooth problems such as pain from a cracked tooth or a simple cavity in the tooth surface will not cause discernible thermographic findings. Thermography has been shown to be useful in detecting major or chronic dental infections, however (Figure 10.36).85 Persistent tooth root infection may create a minor (and often overlooked) warm area lateral to the infected area. A more developed dental abscess will cause localized soft-tissue swelling and warmth that is thermographically apparent. Herpes labialis (cold sores) may be detected in the prodromal and active stages as a warm area over the symptomatic site. Thermal findings return to normal on resolution of the viral attack.86

Thus, this tissue, together with cementum and bone around the tooth root exists at an interface. So, the challenge of gene therapy is identified and deliver multiple signals in the correct order to achieve the regeneration or maintaining these kinds of complex tissues (Scheller et al. 2012).
Oral cavity

Development of the crown always starts with the laying down of dentin. Dentin is formed from the dental papilla. Odontoblasts form a layer of dentin next to the inner dental epithelium. Dentin production continues towards the inside of the tooth.Enamel is formed from ameloblasts. The cells secrete enamel onto the surface of the dentin initially and then gradually build up the layer of enamel on top of the developing tooth.Cementum is formed by cementoblasts that form from the dental follicle. The cementum is laid down at the tooth root to assist in securing the tooth to the adjacent tissues.The periodontal ligament develops as a connection between cementum and the bone socket into which the tooth sits.
General dentists staffing requirement based on workload in the public dental health centers in Turkey
Published in International Journal of Healthcare Management, 2022
The findings relating to professional activities and the mean time required to perform these activities by the dentists working at PODHCs are given in Table 2. Table 2 presents the analysis results in detail regarding the annual number of activities and staffing requirement in the PODHCs. The number of dentists required for each activity was calculated separately. For example, the mean time required for a milk tooth extraction is 8 min, and this activity is performed 15,730 times annually; therefore, the exact number of dentists required for this activity is 1.23. A permanent tooth extraction takes 21 min on average and is performed 62,246 times annually; thus, the exact number of dentists required for this activity is 12.79. Finally, the milk tooth root canal treatment takes 38 min on average and is performed 395 times annually, which yields a dentist requirement of 0.15. All the activities were calculated in the same way as in the example.
A randomized clinical trial of hyaluronic acid gel pulpotomy in primary molars with 1 year follow-up
Published in Acta Odontologica Scandinavica, 2022
Gökçe Çiçek Ildeş, Batın Ilgıt Sezgin, Alexandre Rezende Vieira, Ali Mentes
The selection criteria included children without history of systemic diseases or allergic reactions, absence of requirement for general anaesthesia or sedation and who had good cooperation according to the Frankl Behaviour Scale. The criteria for the selection of treatment of primary molar was as follows: Clinically deep caries lesions without any (1) spontaneous, continuous pain in the tooth, (2) pathological or physiological mobility, (3) abscess and/or fistula, (4) tenderness to palpation or percussion, and (5) the tooth can be restored with a stainless steel crowns (SSC) or a composite filling material after treatment; and radiographically without any (1) the physiological resorption in the tooth root not exceeding 1/3, (2) pathological resorption in the tooth root canals internally and/or externally, (3) radiolucency in the periapical or furcation regions, (4) enlargement of periodontal ligaments. Exclusion criteria were families who were not willing to join the study; children who had any disorders or spontaneous pain; no restorable primary molars or may exfoliate soon and teeth with apical periodontitis, pulp necrosis, abscess, fistula, swelling or mobility.
Profile of intrusive luxation and healing complications in deciduous and permanent teeth – a retrospective study

Deciduous teeth may present several types of healing complications from dental intrusion, such as pulp necrosis, enamel discoloration, internal and/or external root resorption, ankylosis and pulp canal obliteration [6–8]. Furthermore, there is always a potential chance of some disturbance in the eruption or formation of the permanent teeth due to the close proximity of the deciduous tooth root to the developing permanent tooth germ [6,9]. Alternatively, when intrusion occurs in permanent teeth it could potentially lead to healing complications, such as pulp necrosis, inflammatory radicular resorption, ankylosis, loss of marginal bone support, pulp canal obliteration, paralysis or disturbance of the radicular development and gingival retraction [10,11]. In addition to the clinical and radiographic healing complications, dental trauma may cause pain, as well as aesthetic and functional problems that affect the quality of life of children [6,12,13].
