ABSTRACT
@#Periodontitis is a chronic inflammatory disease that is initiated by bacteria. Pathogens and their virulence factors alter normal cellular metabolic activity and deteriorate periodontal microconditions. Owing to the complexity of tooth structure and the limitation of conventional treatment, we may not live up to all patients’ expectations, especially those with grade C and stage Ⅲ or Ⅳ periodontitis. With the advantages of bactericidal effects, high safety, inhibition of bacterial drug resistance and promotion of tissue healing, photodynamic therapy （PDT） seems to be an ideal technology in periodontal treatment. However, it cannot remove subgingival stones and still cannot replace mechanical treatment to preliminarily control periodontal inflammation. Therefore, near-infrared low-energy light combined with traditional photosensitizers is mostly used in clinical periodontal adjuvant treatment. In periodontal maintenance treatment on a regular basis, a single application can also reduce the sensitivity of patients and effectively control plaque, but its effect will be affected by the degree of periodontal inflammation, the concentration and type of photosensitizer, the energy of the light source, etc. With the further development of material science, the performance of photosensitizers to accelerate oxides and target bacteria will be optimized. In the future, parameters of PDT need to be designed in large-scale studies in accord with different stages and grades of periodontitis.
ABSTRACT
OBJECTIVES: This study aimed to contribute to the development of an oral health education program on organized professional toothbrushing by determining its effects on plaque control in patients undergoing orthodontic treatment. METHODS: The subjects in the experimental group participated in the professional toothbrushing and oral health education weekly for 4 weeks, and those in the control group participated in the same program without professional toothbrushing education. RESULTS: The difference in knowledge, attitude, and behaviors on oral health was higher among the experimental group who underwent professional toothbrushing and oral health education program than those in the control group. The effects of toothbrushing time on the plaque index were significantly lower in experimental group than those in the control group. CONCLUSIONS: It is suggested that adequate oral health and professional toothbrushing education program should be implemented to improve oral health.

Objetivo: Evaluar la eficacia de cuatro cepillos dentales de diferente diseño (Colgate Microsonic®, Colgate Twister Fresh®, Colgate 360 Sensitive® y Colgate 360®) para determinar si existe superioridad clínica en la remoción de placa bacteriana de alguno de ellos mediante la técnica de Bass modificado en estudiantes de salud oral de la ciudad de Cali. Materiales y métodos: Se trata de un ensayo clínico aleatorizado que compara la eficacia de cuatro diseños de cepillos dentales a través de diferentes técnicas de cepillado en 200 estudiantes de dos programas de entrenamiento de auxiliares de salud oral, de sexo femenino, con edades comprendidas entres los 15 y 43 años, escogidos por conveniencia y los cuales conformaron los grupos control (cualquier técnica de cepillado) e intervención (técnica de cepillado de Bass modificado). El seguimiento fue realizado durante 21 días a través de la aplicación del Índice de placa bacteriana de O´leary realizada por un odontólogo. Resultados: El cepillo Colgate Twister Fresh® (33%) tuvo mayor probabilidad de reducir el índice de placa bacteriana en cualquier momento del seguimiento cuando se comparó su eficiencia con la de los otros cepillos. La técnica modificada de Bass tuvo mayor probabilidad de reducir placa bacteriana que otras técnicas pero de igual forma esta diferencia no fue significativa. Conclusiones: No se encontró diferencia significativa entre las técnicas de cepillado tenidas en cuenta en este estudio. Ninguno de los cuatro diseños de cepillos empleados en este estudio presentó significancia estadística respecto a la eliminación de la placa bacteriana.
Aim: To evaluate the efficacy of four different designed toothbrushes (Colgate Microsonic®, Colgate Twister Fresh®, Colgate 360 Sensitive® y Colgate 360®) to determine the clinical advantage on removal of plaque using modified Bass technique in dental hygiene students in Cali. Methods: This is a controlled clinical trial to compare the efficacy of four toothbrushes designs with different tooth brushing methods in 200 female dental hygiene students with ages from 15 to 43. Control group used any tooth brushing technique whereas test group used modified Bass technique. Follow up was made daily for 21 days with O´Leary Plaque Index. Results: Colgate Twister Fresh® toothbrush had more probability to reduce plaque index at any time of follow up period than other toothbrushes. Modified Bass technique had more chance to reduce plaque than other techniques but with no significant differences. Conclusions: there were no statistically significant differences between tooth brush techniques. None of the four designs of studied toothbrushes showed differences in regard to plaque elimination.
