Invasive Management

Pits and fissures on the occlusal surfaces of posterior teeth are sites affected commonly by demineralisation caused by the caries process. Clinicians face daily challenges in detecting these lesions, accurately diagnosing their activity and choosing from a range of management options. Traditionally, the detection of an active (or potentially active) occlusal lesion invariably resulted in the preparation of a standardised occlusal cavity, often extending beyond the confines of diseased tissue, followed by the insertion of a direct restorative material, most commonly dental amalgam. The overwhelming weight of contemporary evidence now favours minimally invasive (MI) operative management when required (usually after non-operative prevention has failed), and a wide range of equipment, materials and operative techniques is available to help operators to preserve the maximum amount of healthy/repairable tooth tissue and to allow restoration with more biologically respectful, tooth-preserving materials. This paper aims to provide clinicians with practical guidance in the prevention, early detection, predictable diagnosis and minimally invasive management of early occlusal carious lesions.

Selective Caries Removal

Abstract Background Dental caries is one of the most prevalent non-communicable disease globally and can have serious health sequelae impacting negatively on quality of life. In the UK most adults experience dental caries during their lifetime and the 2009 Adult Dental Health Survey reported that 85% of adults have at least one dental restoration. Conservative removal of tooth tissue for both primary and secondary caries reduces the risk of failure due to tooth-restoration, complex fracture as well as remaining tooth surfaces being less vulnerable to further caries. However, despite its prevalence there is no consensus on how much caries to remove prior to placing a restoration to achieve optimal outcomes. Evidence for selective compared to complete or near-complete caries removal suggests there may be benefits for selective removal in sustaining tooth vitality, therefore avoiding abscess formation and pain, so eliminating the need for more complex and costly treatment or eventual tooth loss. However, the evidence is of low scientific quality and mainly gleaned from studies in primary teeth. Method This is a pragmatic, multi-centre, two-arm patient randomised controlled clinical trial including an internal pilot set in primary dental care in Scotland and England. Dental health professionals will recruit 623 participants over 12-years of age with deep carious lesions in their permanent posterior teeth. Participants will have a single tooth randomised to either the selective caries removal or complete caries removal treatment arm. Baseline measures and outcome data (during the 3-year follow-up period) will be assessed through clinical examination, patient questionnaires and NHS databases. A mixed-method process evaluation will complement the clinical and economic outcome evaluation and examine implementation, mechanisms of impact and context. The primary outcome at three years is sustained tooth vitality. The primary economic outcome is net benefit modelled over a lifetime horizon. Clinical secondary outcomes include pulp exposure, progession of caries, restoration failure; as well as patient-centred and economic outcomes. Discussion SCRiPT will provide evidence for the most clinically effective and cost-beneficial approach to managing deep carious lesions in permanent posterior teeth in primary care. This will support general dental practitioners, patients and policy makers in decision making. Trial Registration Trial registry: ISRCTN. Trial registration number: ISRCTN76503940.

Sealing the pits and fissures of posterior teeth represents a local and specific method of caries prevention. The aim of this study was to evaluate the adhesion of two materials used in sealing pits and fissures: Pitt and Fisure and Fissurit FX (Voco), with the help of the scanning electronic microscope (SEM). The results of the study revealed a much higher quality of the Fissurit FX (Voco) product both in terms of adhesion to the enamel and material homogeneity. The Pitt and Fisure product showed a high degree of detachment from the enamel, marginal infiltration, large particles and a high concentration of inorganic particles.

Posterior Ankle Arthroscopy

Background: Osteochondral lesions of the talus are frequent pathologies of the ankle joint. Especially through arthroscopy, the treatment is kept as minimally invasive as possible. However, there are some drawbacks as to the reachability because of the high congruency of the ankle joint. Here, either noninvasive distraction or maximal dorsiflexion may be an option for better access to the lesion. The purpose of this study was to evaluate maximal dorsiflexion compared to neutral position or noninvasive distraction of the ankle joint in the arthroscopic reachability of the talar dome. The hypothesis of this study was that maximal dorsiflexion would allow for greater accessibility of the talar dome compared to neutral position or noninvasive distraction of the joint. Methods: Twenty matched pairs (n=40) of anatomical ankle specimens were used. The effects of neutral position, maximal dorsiflexion, and noninvasive distraction of the ankle joint on arthroscopic accessibility of the ankle joint were tested. After disarticulation of the talus, reach was measured and compared between the 3 positions. Results: In neutral position, 13.7±1.2 mm of the talar dome was reached laterally and 14.0±1.0 mm medially. In maximal dorsiflexion, the distance was 19.0±1.1mm laterally and 19.8±1.4 mm medially, and in noninvasive distraction it was 16.1±1.5 mm laterally and 15.7±1.0 mm medially. The statistical comparison showed a significantly better reach in dorsiflexion laterally ( P = .003) and medially ( P = .026). Conclusion: Accessibility of the talar dome in maximal dorsiflexion was superior to that in neutral position or noninvasive distraction. Clinical Relevance: Results of this study may allow for better planning in arthroscopic treatment of osteochondral lesions of the talus.

Clinical Correlations

Medical curricula are continually evolving and increasing clinical relevance. Gross anatomy educators have tested innovations to improve the clinical potency of anatomic dissection and found that clinical correlations are an effective method to accomplish this goal. Recently, surgical educators defined a role for laparoscopy in teaching anatomy. We aimed to expand this role by using surgical educators to create clinical correlates between gross anatomy and clinical surgery. We held supplements to traditional anatomy open dissection for medical students, including viewing prerecorded operative footage and live laparoscopic dissection performed on cadavers. The main outcome measures were assessed through pre- and postsession surveys. Greater than 75 per cent of students found the demonstrations highly valuable, and students perceived a significant increase in their understanding of abdominopelvic anatomy ( P < 0.01). Additionally, 62 per cent of students with previous interest in surgery and 10 per cent of students without previous interest in surgery reported increased interest in pursuing surgical careers. Our demonstrations advance the use of minimally invasive surgical technology to teach gross anatomy. Live laparoscopic demonstrations augment traditional anatomic instruction by reinforcing the clinical relevance of abdominopelvic anatomy. Additionally, laparoscopic demonstrations generate interest in surgery that would otherwise be absent in the preclinical years.

Scissorbite correction of posterior teeth can often be challenging. For adolescent patients, they may occur due to late eruption of the second permanent molar teeth after appliances are removed, or due to operator preference not to include them on the appliance. This case report describes a 17-year-old patient who had previously been treated with fixed appliances but did not originally have second permanent molars bonded. Complete correction of the scissorbite on the UR7 was effectively achieved in 14 weeks using a minimal system comprising only a palatal mini-screw, molar band and elastomeric chain. CPD/Clinical Relevance: Mini-screws placed in a palatal position can provide an effective way to correct posterior scissorbites.

A New Technique

Background and aim: When a mandibulectomy causes discontinuity, the patient will need a rehabilitative prosthesis to achieve a proper occlusal relationship. Technique: This article describes step-by-step guidelines for measuring the patient-specific mandibular guide flange angulation. In the presented technique, the flange angulation is determined by dividing the horizontal overlap of the maxillary posterior teeth plus the maxillary buccal clasp thickness by the vertical distance of the mandibular continuous clasp up to the maxillary buccal clasp. Discussion: The mandibular guiding flange prosthesis must achieve an angulation that is appropriate for the particular circumstances of each patient to minimize the complications with mandibular deviation. Clinical relevance The introduced method for measuring the patient-specific mandibular guide flange angulation can help prosthodontists to prepare the mandibular guiding flange prosthesis with higher accuracy and predictability.
