A clinical case of treatment of two severe intrabony defects on the aesthetic zone is reported and followed for one year. The biomaterial of choice was enamel matrix derivative (Emdogain®; Straumann™) alone with a preservation papilla flap and a minimally invasive surgical technique. After surgical treatment, the patient was kept in a supportive periodontal therapy programme with 6-month interval between appointments. In the one year after surgery appointment, clinical and radiographic changes were observed, showing periodontal health and stability. 

Purpose: To evaluate changes in children with bilateral cleft lip and palate (BCLP) who premaxillary osteotomy and secondary alveolar bone grafting as compared to children with BCLP who are not indicated for surgery, and to determine variables that differentiate patients who do or do not require osteotomy. Material and methods: Twenty-four children with BCLP were included in the study: 12 who underwent osteotomy (intervention group) and 12 who had no surgery (control group). Radiographic and model values of the intervention group were compared before (T1) and after (T2) premaxillary osteotomy, and measurements were compared with those from the control group at T1. Results: Convexity, ANB (point A-nasion-point B), and maxillary depth was more diminished at T2 in children in the intervention group. Point A, anterior nasal spine, and pogonion were retroposed after surgery, and the anterior spine was higher. At T2, the upper incisors were proinclinated and intruded, and overbite was improved. Models revealed increased intermolar intercanine width as well as intrusion of upper incisor after surgery. Premaxilla and upper molars were more extruded, had a higher total maxillary height and increased extrusion of upper incisor in children who underwent osteotomy. Conclusion: After surgery, children who undergo surgery have a premaxilla that is more normalized and more level with the occlusal plane, as well as improved dental inclination. Variables that differentiate children who require osteotomy from those who do not include more extrusion and protrusion of the premaxilla, and a greater extrusion of the upper incisors.

Functional and aesthetic rehabilitation of an extremely worn dentition is one of the most challenging aspects of Prosthodontics. A thorough examination and diagnosis & selection of appropriate occlusal scheme are key factors to achieve optimal clinical outcome. Among the variety of techniques suggested in the literature, the twin-stage technique given by Hobo & Takayama has emerged as a popular choice for clinicians in recent times. Instead of the condylar path, it utilizes standard cuspal angle as the main determinant of articulation to produce predictable disocclusion in eccentric movements. It is relatively simple, does not require special armamentarium and can be incorporated easily with commonly used clinical techniques such as face bow transfer. The present case report describes the full mouth rehabilitation of a severely mutilated dentition using Hobo’s twin-stage technique to achieve a functionally and aesthetically favourable outcome.

Introduction: Temporomandibular joint (TMJ) ankylosis is one of the most disruptive anomaly that affects the masticatory system and is referred as permanent movement disfunction of the mandible caused by bilateral or unilateral fibrous or bony adhesions and create problems. The etiology is congenital or idiopathic and include trauma, arthritis, infection, previous TMJ surgery etc. Management requires extensive resection of the ankylotic mass and reconstruction of the ramus-condyle unit with autogenous or alloplastic grafts. Most of the time, combination of surgical treatment with physiotherapy is needed in order to achieve maximum rehabilitation and functionality of the mandible. Purpose: The aim of this study is to present the surgical management of an unusual case of unilateral TMJ ankylosis and recent of literature review. Case report: A thirty-seven-year old patient reported unable moving his lower jaw. Clinical examination revealed unilateral TMJ ankylosis of congenital cause and the lateral movement of the mandible was impossible. The patient surgical treatment included resection of the newly formed bone mass, replacement of the condyle with costo-chondral graft and replaced of articular disc with the temporal fascia. Since and for ten years after surgery the patient shows no signs of relapse. Conclusion: The development of TMJ ankylosis may be congenital or acquired etiology. In order to manage it required a comprehensive clinical and radiographic examination. Surgical resection of the bone and coronoid process on the entire side is necessary and a graft that mimics the articular disc is placed, while it is necessary the immediate postoperative kinesiotherapy.

Parry-Romberg syndrome is an uncommon condition, self-limiting with slow progressive hemifacial atrophy. This syndrome can lead to several progressive congenital and developmental deformities. It can cause severe facial asymmetry and subsequently lead to esthetic and psychological problems and adversely affect patient’s quality of life, so its treatment holds great importance. Still, there is no exact treatment protocol for this disease, treatment approaches are bounded and patient’s response to the treatment is imponderable. However, most of the patients can benefit from conservative treatments. In this paper, we have reported a moderate case of Parry-Romberg syndrome, with no familial history of any syndromes. We also have discussed about present anomalies and the steps of exerted conservative treatments.

Pierre Maria and Sainton syndrome or cleido-cranial dysplasia (CCD) is a rare syndrome presenting an autosomal pattern of inheritance, characterized by characterized by a triad: clavicular aplasia, delayed ossification of the fontanelles and sutures of the vault of the skull. To these may be added multiple dental inclusions.

Background: The present study was conducted to assess effect of cigarette smoking on different denture base material. Materials & Methods: The present study was conducted in the department of Prosthodontics. A total of sixty wax specimens in the shape of circular discs were prepared. These were divided into two groups. Group I (30) specimens were heat‑cured denture base materials and group II (30) specimens were flexible denture base materials. Both specimens were further divided into four subgroups of 15 each. Subgroup I was heat‑cured denture base material specimens (control group), subgroup II was flexible denture base material specimens (control group), subgroup III was heat‑cured denture base material specimens exposed to cigarette smoking (study group) and subgroup IV was flexible denture base material specimens exposed to cigarette smoking (study group). The initial (IRa) and final (FRa) surface roughness was measured before and after smoking test of the specimens. Results: It was observed that in group I, mean IR (µm) value was 0.182 and FR value was 0.572. In group II, mean IR (µm) value was 0.265 and FR value was 0.831. In group III, mean IR (µm) value was 0.195 and FR value was 1.892. In group IV, mean IR (µm) value was 0.291 and FR value was 1.892. The difference was significant (P< 0.05). Conclusion: The surface roughness of the specimens fabricated from the flexible denture base material was found to be more compared to heat‑cured denture base specimens after exposure to cigarette smoke. There is need to educate the patients regarding cleanliness of denture to avoid infection in the oral cavity.

Several articles have discussed mandibular condyle position after bilateral sagittal split osteotomies (BSSO). However, previous studies have sought to establish a relationship between orthognathic surgery and the improvement of temporomandibular joint (TMJ) signs and symptoms. Also, they have been limited to two-dimensional evaluation of condylar position considering only the condylar “sag” or improper inferior seating of the condyle. The purpose of this study was to investigate a relationship between changes in condylar position using three-dimensional computed tomography and the negative clinical impact of BSSO on the temporomandibular joint. 

In our past 200 years we have seen the advancing development of Dental Arts and Science though discoveries by its practitioners. Perhaps it will do some good to review the basis upon which fixed tooth replacement has evolved—that is the prosthetic crown.

Objective: To describe pathological fi ndings on pre-treatment dental panoramic tomograms of edentulous jaws taken before complete denture treatment. Design: Descriptive cross-sectional study. Setting: Prosthetic division, Department of Conservative and Prosthetic Dentistry. School of Dental Sciences, University of Nairobi. Results: Data was obtained from clinical records and OPGs of 163 edentulous patients seen at the prosthetic clinic between 2010 and 2016 for complete denture therapy. From history and examination alone, clinicians reported significant findings on 50.3% of records, while 43.6% had no such findings. Ten (10) (6.1%) records were unclear. Examination of OPGs revealed 79.1% of the films had no pathological findings while in 20.9% had. Most of the findings (70.0%) were retained roots, 6% were radio-lucencies, 12% were other radio-opacities, 9% were impacted teeth while 3% had both retained root and radio-opacity. Most pathologies (64%) were located in the posterior region of jaws while the other findings were evenly distributed in the anterior and posterior regions of the jaws. There was no predilection of pathological findings to any other factor other than gender. In 83.4% records, queries on clinical notes coincided with significant findings on OPGs; while 16.6% were either unclear or did not coincide. Most (71%) OPG findings led to modification of treatment plan. Conclusion: Pathological findings are common on pre-treatment OPGs. It may be good practice to take an OPG for edentulous patients prior to complete denture therapy where such services are available, to prevent complications from intra-bony pathologies. However, Most of the findings are either detectable by clinical exam or may not be of major consequence to the health of patients. Complete denture may be done without OPGs for new and old denture wearers where the service is not available.
